ForewordWhat’s new?The new structure for horticulture within the NSW Department of Primary Industries (NSW DPI) has been bedded down, positioning us as the premier organisation delivering research and development (R&D) outcomes to the horticultural industries of NSW.
As a key component of that change we have appointed seven new industry-facing Development Officers (DOs) to work alongside our research teams and help deliver on the goals and strategies of the horticultural industries.
These positions will be aligned with those industries that are a major focus for us under the National Research Framework for R&D.
The following DOs have been appointed:
Leader Horticulture Myles Parker, Orange Development
Viticulture Jason Cappello, Griffith
Blueberries Phillip Wilk, Wollongbar
Citrus Steven Falivene, Dareton
Macadamias Jeremy Bright, Wollongbar
Protected Cropping Jonathan Lidbetter, Ourimbah
Temperate Fruit Kevin Dodds, Tumut
Vegetables Tony Napier, Yanco
The DOs will be responsible for working within R&D programs and taking the outcomes and delivering them to industry.
The role of the DOs is primarily to support capacity building and industry growth through the adoption of new information and technologies. These are positions with state-wide responsibility for their respective industries.
The Grapevine management guide 2013–2014 is one of NSW DPI's flagship publications. Such publications are a crucial means of packaging information for producers, and as such I recommend this current edition to you.
Full contact details for the recently appointed DOs and Leaders are provided in this guide.

Managing fungicide resistance in Australian vineyardsBARBARA HALL (PROJECT LEADER), SOUTH AUSTRALIAN RESEARCH AND DEVELOPMENT INSTITUTE, ADELAIDESUZANNE MCKAY, SOUTH AUSTRALIAN RESEARCH AND DEVELOPMENT INSTITUTE, ADELAIDESANDRA SAVOCCHIA, NWGIC, WAGGA WAGGA
What is fungicide resistance?Fungicide resistance occurs when a plant-disease-causing organism is able to survive exposure to doses of a fungicide that would normally control it.
Resistance is usually due to a genetic mutation that enables the fungus to overcome the activity of a fungicide. Each fungal population may contain a very small number of individuals that have this mutation and can survive the application of a particular fungicide.
If the same fungicide or fungicides from the same activity group are used repeatedly and exclusively, the susceptible individuals are killed but those with natural resistance survive, multiply and become dominant. Fungicide-resistant populations add to the cost of managing a vineyard owing to reduced fungicide efficacy and failure of spray programs to manage disease.
Although industry is advised to follow recommended anti-resistance strategies, there is confusion over which compounds are best to use as mixtures or in alternation. More information on managing fungicide resistance can be found on the web site of CropLife Australia (www.croplifeaustralia.org.au).
Fungicide resistance in AustraliaBotrytis bunch rot, powdery mildew and downy mildew are the three most economically important diseases in Australian vineyards.
Fungicide resistance in the pathogens causing these diseases have been reported within the grape industry, including Botrytis cinerea (botrytis bunch rot) resistance to the fungicide groups dicarboximide (e.g. Rovral®) and anilinopyrimidine (e.g. Scala®), Plasmopara viticola (downy mildew) resistance to metalaxyl, and Erysiphe necator (powdery mildew) resistance to the DMI (demethylation-inhibiting) group of fungicides.
The most recent report of fungicide resistance was of E. necator to the QoI (strobilurin) group of fungicides. As this group of fungicides is also used to control downy mildew, it is vital to determine whether resistance also occurs in P. viticola populations in Australia.
Future project to understand fungicide resistance in Australian vineyardsIt is important to establish the occurrence and geographical distribution of fungicide resistance so that spray programs can be adapted to maintain optimum efficacy.
The viticulture industry needs access to tests for rapid and accurate detection of fungicide resistance. Apart from those used for B. cinerea, tests are currently not available for routine testing at a population level owing to the time and resource demands of conventional phenotyping and genotyping methods.
The genetic basis of resistance is known in some cases and not in others, so this project will combine both phenotypic and genotypic tests to monitor fungicide resistance development in the three pathogens of greatest economic importance to the Australian wine grape industry.
A collaborative project funded by the GWRDC has been established among researchers in SA, NSW and WA. It aims to:
• determine the occurrence and distribution of populations of E. necator, P. viticola and B. cinerea resistant to at-risk fungicides within Australia
• validate high-throughput genotypic testing by using established DNA markers and next-generation DNA sequencing techniques to develop rapid and accurate tests to detect resistance in pathogen populations
• develop and evaluate effective and sustainable resistance-management strategies for the at-risk fungicides
• disseminate the information to industry.
Sample collectionSamples collected from the main viticultural regions of Australia, with collaboration from industry and agrochemical representatives, will be sent to, and processed by, one of three research organisations.
Powdery mildew samples will be processed by the South Australian Research and Development Institute (SARDI), downy mildew by the National Wine and Grape Industry Centre (Charles Sturt University, NSW) and botrytis bunch rot by the Australian Centre for Necrotrophic Fungal Pathogens (Curtin University, WA).
Industry Groups, companies and representatives are invited to participate in this project by supplying sample materials for analysis. Interested people can contact the key people below for further information and instruction.

SummaryThis GWRDC-funded project is a collaboration among SARDI, Charles Sturt University, Curtin University, the Department of Agriculture and Food Western Australia, the Australian Wine Research Institute, the University of Adelaide and other industry partners.
This project will provide comprehensive information on the fungicide sensitivity and distribution of the key pathogens affecting Australian vineyards. It will also
improve our knowledge of the mechanisms of fungicide resistance.
All of the information will contribute to improved fungicide resistance management strategies through collaboration with CropLife, agrochemical companies and industry.
Maintaining effective use of all of the fungicide groups will help substantially to reduce the economic and environmental impacts of disease in Australian viticulture into the future.

The recommendation for export wine is ‘Use no later than E-L 31, berries pea-size (7 mm diameter).
Resistance management strategyThe CropLife Australia powdery mildew resistance management strategy for Group 11 fungicides now comprises the following points: • Apply Group 11 and other systemic fungicides
preventively. • DO NOT apply more than two sprays per season of
Group 11 fungicides. • Where Group 11 products have been routinely used
for many seasons, field research indicates there is an increased risk of powdery mildew resistance to Group 11 fungicides occurring. To ensure continued protection against powdery mildew in these circumstances, either abstain from using Group 11s or mix Group 11 fungicides with a registered rate of a compound from an alternative chemical group for the control of powdery mildew in grapes.
• Alternatively, if applied alone, Group 11 fungicides should be used in strict alternation with fungicides from an alternative chemical group for the control of powdery mildew.

New requirements for the movement of Phylloxera Exclusion Zone winegrapes for accreditation under ICA-33BEV ZUBBO, SENIOR PLANT BIOSECURITY OFFICER, NSW DPI, WAGGA WAGGA
IntroductionThe requirements for movement of wine grapes between Phylloxera Exclusion Zones within NSW and interstate have changed.
For regular updates visit www.dpi.nsw.gov.au/biosecurity/plant/phylloxera-winegrapes-ica-33
NSW DPI, Biosecurity South Australia, the Department of Environment and Primary Industries Victoria (DEPI Vic) and the Wine and Grape Industry have worked together to simplify the documentation required for movements of the 2013 wine grape vintage and for grape movements into the future.
Put simply, only 1) NSW grape growers sending to South Australia and 2) NSW wineries receiving Phylloxera Risk Zone grapes need to be accredited under Interstate Certification Assurance (ICA)-33, Movement of Winegrapes.
Producers and wineries will need to familiarise themselves with Cart Notes, Queensland fruit fly outbreak areas and Phylloxera zones (see below) to meet the new requirements.
Note that the information supplied here is subject to change without notice. Before they consign produce, growers should always contact the responsible government department in the destination state to confirm that state’s entry requirements.
Cart NotesThe Cart Note must travel with each consignment. It must be kept by the winery for a minimum of 2 years and must be made available to an inspector upon request.
The Cart Note must contain at least the following information:
• grower’s name, contact details and the (physical) address of the property on which the wine grapes were grown
• name and physical address of the receiving winery
When using a cart note to enter any part of NSW, you must ensure at least the following information is captured on the cart note:
Figure 1. An example of a Cart Note and the minimum information required.
Vineyard m
anagement

• quantity of wine goods supplied to the winery
• variety of the grapes
• name and signature of the signatory
• date the document was endorsed.
Figure 1 is an example of a Cart Note. It shows the minimum information required to meet NSW certification requirements.
Please note that although ICA-33 is still required for grapes to enter South Australia, an option for issuing Cart Notes under ICA-33 for entry into South Australia from NSW is being pursued. Cart Notes issued under ICA-33 are likely to require more information than those required to enter NSW; growers should contact Biosecurity South Australia for further information.
Queensland fruit fly outbreak Grape growers and wineries should check to see whether the grapes are being loaded within, or will pass through, a Queensland Fruit Fly outbreak. For outbreak information see the following web sites:
• NSW: www.dpi.nsw.gov.au/responses/qff
• Victoria: www.depi.vic.gov.au/agriculture-and-food/pests-diseases-and-weeds/pest-insects-and-mites/queensland-fruit-fly
Phylloxera zone mapGrape growers and wineries should check to see where the Phylloxera exclusion, risk and infested zones (www.phylloxera.com.au) are located (Figure 2).
Information for growersMovement conditionsWine grapes moving into the NSW and Victorian Sunraysia Pest Free Area (PFA) need to be securely transported and processed within 24 hours of arrival. Note: No changes have occurred for wine grapes originating from Phylloxera Risk Zones; these wine grapes must still be certified under ICA-33 and be received by an ICA-33 accredited winery.
Certification requirements for Phylloxera Exclusion Zone wine grapesIn addition to being securely transported and processed within 24 hours, wine grapes moving into the NSW portion of the PFA must be accompanied by at least a Cart Note, depending on where the consignment originates from (see Table 1).
If you are moving locally within the Victorian Northern and Southern suspension zones, there are no requirements. Please contact DEPI Vic for information on the areas covered by these zones or any other queries in relation to movement conditions for wine grapes moving into Victoria from NSW.
Figure 2. Current Phylloxera management zones of Australia

Loads going from NSW into Victoria can also be moved under a Cart Note without ICA-33 accreditation. Contact DEPI Vic for further information.
As a general rule for NSW growers, if you ensure your load is securely transported and the grapes are accompanied by a Cart Note and processed at the winery within 24 hours, then you can send wine grapes anywhere in NSW and Victoria.
Loads going from NSW into South Australia still require full certification under ICA-33 and must meet the conditions of that arrangement. South Australia is considering an allowance for issuing Cart Notes under ICA-33 in place of a Plant Health Assurance Certificate. Cart Notes issued under ICA-33 will require more information than that required to enter NSW. Please contact Biosecurity South Australia to confirm movement conditions and certification requirements for wine grapes moving into South Australia from NSW.
See Table 1 for a full explanation of movement conditions and certification requirements by origin and destination in NSW.
Information for wineriesFirst, you are required to keep all Cart Notes that arrive with consignments of wine grapes for at least 2 years and to make them available to a DPI inspector upon request. Please remember that Cart Note information must also be kept in accordance with the Commonwealth Wine Australia Corporation Act 1980 as part of the Label Integrity Program.
Second, you need to be accredited under Part B of ICA-33 only if you receive grapes from the Phylloxera Risk Zone. Grape growers in the Phylloxera Risk Zone still need to be accredited under Part A of ICA-33 and must follow all conditions of this arrangement.
Lastly, wine grapes grown in Phylloxera Infested Zones are still prohibited from entry into, or movement within, NSW.
What do growers do in the following situations?I am a grower who sends some or all of my wine grapes to South Australia.You need to be accredited under ICA-33 and follow all conditions of this arrangement. Make sure that you reapply before your current accreditation expires. Contact Biosecurity South Australia for the specifics of consigning wine grapes under ICA-33 to South Australia.
I am a grower outside the NSW Phylloxera Exclusion Zone (e.g. Hunter Valley), and I send all of my wine grapes to NSW and Victorian wineries.Good news, you don’t need to be accredited under ICA-33 and you don’t need to send a Plant Health Assurance Certificate or Plant Health Certificate with your wine grapes. However, if you send into the PFA you will need to secure your loads and send a Cart Note with each load. You may continue to use ICA-33 if you wish.
I am a grower inside the Phylloxera Exclusion Zone, and I send all of my wine grapes to NSW and Victorian wineries in the Victorian Suspension Zones.Good news, there are no requirements for this movement. Please contact DEPI Vic for more details regarding the location of the Victorian Suspension Zones.

The conditions specified in this table apply only to movements of wine grapes originating from a Phylloxera Exclusion Zone.* A Cart Note must travel with each consignment of wine grapes and be kept by the receiving winery for at least 2 years and made available to a NSW DPI inspector upon request. Growers may continue to use a Plant Health Assurance Certificate issued under ICA-33 or a Plant Health Certificate issued by an Inspector in place of a Cart Note.‘Secure Load’ means secured so as to prevent spillage during transport. This is left to the discretion of the transporter/vineyard.

Tocal College – specialised training to rural industries
rto number 91166
Tocal College is a leading Australian Provider of specialised training to rural industries. It consists of CB Alexander Campus at Paterson and the Murrumbidgee Rural Studies Centre at Yanco, with education staff also located at Camden, Gosford, Tamworth and Wagga Wagga.
Tocal offers adult education through delivery of PROfarm short courses and external courses and through skills recognition (life experience) programs.
Skills Recognition (Life Experience) ProgramSkills recognition is sometimes referred to as Recognition of Prior Learning (RPL). Skills Recognition gives formal credit for the knowledge and abilities you have already gained through life, in formal course work at recognised institutions, or by attending workshops and short courses.
Skills recognition is available for a range of qualifications, including the nationally recognised Diploma in Horticulture and the Diploma of Agriculture. It reduces the number of units you need to study to complete these qualifications. Skills recognition gives you a flying start and allows you to build knowledge and skills gained through short courses towards a full qualification.
PROfarm Short CoursesThe PROfarm program consists of over 100 specialist courses in agriculture, conservation and land management, natural resource management, farm business management and other rural industry areas.
Courses range in length from one to five days and are designed to meet the needs of farmers, primary industries, agribusiness and the community. The courses focus on real-world issues and are delivered throughout New South Wales by specialist extension and education staff of NSW Department of Primary Industries. For details see www.profarm.com.au
External Courses Tocal College offers external courses at diploma level in agriculture and in conservation and land management. These courses provide the opportunity for specialisation in areas such as integrated weed management, farm business management and vertebrate pest management.
Tocal’s external courses feature a blend of skills recognition (see above) and structured study units.
TraineeshipsThe College provides industry traineeships in agriculture, horticulture, irrigation and wine industry operations. Trainees are expected to attend training on a part time basis.

Herbicide resistanceMARCEL ESSLING, SENIOR VITICULTURIST, AUSTRALIAN WINE RESEARCH INSTITUTE, URRBRAE SA
There have been reports of herbicides failing to control weeds in vineyards. To minimise the chance of resistance, the following integrated weed management principles should be incorporated into all herbicide programs.
• Don’t rely solely on chemical techniques for weed control. Grazing, mulching, cultivation, slashing and adding a competitive cover crop can reduce weed pressure.
• Rotate mode-of-action groups within and across years. Consider using tank mixes of different actives if labels recommend this.
• Read and follow label directions carefully, making note of the correct doses and timings.
• Identify and monitor your surviving weed populations, and check for resistant weeds.
• If you suspect failure, don’t use the same product or group again.
• Control weed escapes before the weeds set and shed viable seed.
The greatest resistance problem in vineyards is with glyphosate-resistant ryegrass. Tests by the University of Adelaide’s Weed Science Group have found resistance in 20 ryegrass samples from vineyards in South Australia, and the total number of confirmed cases of glyphosate resistance in ryegrass in that state is now 150. It is likely that there are hundreds more unconfirmed cases. The herbicide activity groups that are registered for viticulture and that carry an increased risk of causing resistance are listed below.
HIGH RESISTANCE RISK herbicidesGroup A (fluazifop, haloxyfop and quizalofop). The key recommendation for preventing Group A resistance in grass weeds is not to use them two seasons in a row, irrespective of how well they worked the previous season.
MODERATE RESISTANCE RISK herbicidesGroup C (simazine, diuron, propanil and bromoxynil). Resistance to this group is known to exist in a range of weeds in horticulture. Always use the label rate, apply to weeds at the critical growth stage (as stated on the label) and ensure that no weeds set and shed viable seed.
Group D (oryzalin, pendimethalin and trifluralin). Resistance is known in an increasing number of populations of annual ryegrass, so where possible avoid this group where ryegrass is dense. Rotate Group D with other groups.
Group F (diflufenican). Resistance is known in wild radish and mustards. Avoid applying this group in consecutive years unless one application is a mixture with another group that is active on the same weed, or unless a follow-up spray (with a different group) is applied to those weeds that are not controlled.
Group J (2,2-DAP). Resistance is possible in a range of weeds (especially annual ryegrass). To delay resistance, rotate groups and don’t cut herbicide rates. Use the maximum rate for annual ryegrass.
Group K (napropamide). Avoid use on dense populations of annual ryegrass. Consider using alternative methods of weed control to reduce weed numbers before applying herbicides.
Group L (diquat and paraquat). Resistance exists in a range of weeds such as ryegrass, barley grass and capeweed. Vineyards are considered a high resistance risk where frequent applications are made each season or cultivation is not used. Rotate group L with other knockdown herbicides. Where possible, use residual herbicides that are effective on the same weeds and use alternative modes of action to selectively control grass and broadleaf weeds. Consider following a glyphosate application 1 to 7 days later with a full-cut cultivation or spraying with a paraquat-based product.
Group M (glyphosate). Resistance to this group occurs commonly when there has been intensive (year-to-year) use, lack of rotation of other herbicides, or little or no cultivation following the glyphosate application.
Group Q (amitrole). Annual ryegrass resistance is rare in Australia but has occurred. Alternate Group Q with herbicides with other modes of action, and consider alternative methods of weed control before applying herbicides.
The Australian Wine Research Institute (AWRI) acknowledges CropLife Australia’s Herbicide Resistance Management Strategies. You should consult the full document at www.croplifeaustralia.org.au. The AWRI is grateful for the help of Dr Peter Boutsalis and Andrew Weeks in reviewing this document.

Herbicides for use in vineyardsJASON CAPPELLO, DEVELOPMENT OFFICER – VITICULTURE, NSW DPI, GRIFFITHGREGORY MOULDS, SENIOR LAND SERVICES OFFICER – HORTICULTURE, LOCAL LAND SERVICES, BURONGA
Herbicide groups (see following tables)
• High Risk: Groups A
• Moderate Risk: Groups C–Q
Remember:
• Read and follow the label directions of registered herbicide products before using.
• Calibrate spraying equipment and provide sufficient agitation of herbicide in tank, especially when using WP – wettable powder WG – wettable granules DF – dry flowable SC – suspension concentrate.
• Consult the label for recommendations for use of wetting agents.
• Practise herbicide-resistance minimisation strategies.
Check withholding periods of herbicides before use, as well as rainfast times.
Table 3 lists post-emergent herbicides registered in NSW for use in vineyards. Table 4 lists the residual herbicides registered for use in vineyards, and Table 5 shows non-selective post-emergent herbicides registered for grapevine sucker control in vineyards.
Remember: Read the product label before using a herbicide.

Root knot nematode and grapevine resistanceLOOTHFAR RAHMAN, FORMER PLANT PATHOLOGIST, NWGIC, WAGGA WAGGAJASON CAPPELLO, DEVELOPMENT OFFICER VITICULTURE, NSW DPI GRIFFITHMELANIE WECKERT, RESEARCH PLANT PATHOLOGIST, NWGIC, WAGGA WAGGA
BackgroundRoot knot nematode species (Meloidogyne javanica,
M. incognita, M. arenaria and M. hapla) are considered
the most important and damaging grapevine plant
parasitic nematodes in Australia. Of them, M. javanica is
predominant in most grape-growing regions in Australia.
The second-stage juveniles (J2) of the nematode live in
the soil and initiate infection in the young feeder roots.
Once it enters the roots, the nematode establishes a
feeding site within the root tissues and starts drawing
the root cell contents from the site into its body.
As a result, rapid cell division and enlargement occurs at
the feeding site of an infected root cell. Thus the infected
cells swell to form a characteristic ‘gall’ or ‘knot’ in the
roots, which may contain one or several females.
The ‘galls’ can be seen if the roots of an infected vine
are dug out from soil. Inside the galls, the nutrient-
conducting tissues are damaged and thus the roots are
unable to take up or transport nutrients or water from
the soil to the aboveground parts of the vine.
Once the nematode become well established inside the roots over time, external symptoms such as stunted growth, leaf yellowing and yield decline become evident.
Yield loss can range from 7% to 20% in most cultivars but may increase up to 60% over time, depending on the susceptibility of the cultivars and the duration and severity of nematode infection. In severe cases of infection, a vineyard will require replanting with a resistant rootstock.
Life cycleBecause root knot nematode species are internal parasites of roots, they develop and reproduce inside the roots.
There are six developmental stages: the eggs, four juvenile (J) stages and an adult stage. The J1 stage develops inside the egg and hatches out as the J2 stage. The J2 stage lives in the soil, enters the young feeder roots and develops into the J3 and J4 stages (immature females) and adult female stage inside the roots.
The adult females lay eggs into a gelatinous matrix, where they are protected and can survive under adverse conditions. The female nematodes with the egg masses

protrude through the outer cell layer of the roots; thus the eggs are released into the soil.
These developmental phases are repeated again and again. The average generation is about 3 to 5 weeks, depending on the environmental conditions.
A single female nematode may produce several hundred eggs at a time; thus a low population at planting can build up to a high population over time. This population increase will also increase yield loss gradually in a vineyard planted with a susceptible cultivar. The nematode is less active in winter.
Management optionsComplete eradication of the root knot nematode from a newly planted or established vineyard is very unlikely.
However, application of chemicals (e.g. Nemacur®) in the soil, cultivation of biofumigation crops (e.g. mustard, turnip) in the inter-row space and incorporation of organic amendments (e.g. mustard seed meal, chicken litter, biochar) into the undervine and/or inter-row soil for a few consecutive years may reduce the population density to below the damage-risk threshold (<200 J2 individuals/kg dry soil).
Alternatively, despite its high initial cost, planting resistant rootstocks is a sustainable and long-term
solution to overcome the root knot nematode problem in an infested vineyard.
Several root-knot-nematode-resistant rootstocks have been developed and are commercially available in Australia (see below). In contrast, it is believed that all own-rooted cultivars are susceptible to root knot nematode. However, the degree of susceptibility may vary between cultivars.
Recently, at NWGIC we tested six rootstocks and 14 varietal clones to verify their susceptible or resistant reactions to root knot nematode (M. javanica) under glasshouse conditions.
All the tested clones are popularly grown across grape-growing districts. We classified the tested rootstocks and varietal clones on the basis of the number of galls present in each root system and the number of J2 stage and female nematodes per gram of roots (Table 6).
On the basis of this classification, Ramsey A11V2 and Dogridge A6V8 were rated as highly resistant (HR), 5C Teleki 10-48-49 Gm and K-51-40 Lider D13V15 as resistant to highly resistant (R-HR), and 1103 Paulsen 200HT and 140 Ruggeri Q45-3A as moderately resistant to resistant (R).
All the tested varietal clones showed susceptible (S) to highly susceptible (HS) reactions (Table 6).

Some suggestions to consider• Before planting, test your vineyard soil for the
presence of nematodes. • Take appropriate nematode control measures before
planting with rootstocks or own-rooted cultivars (if your vineyard soil is infected).
• Check that rootlings are free from any root knot nematode galls before planting.
If you purchase rootlings with root knot nematode galls, ask the nursery whether they have been hot-water-treated, or return them to the nursery. For confirmation, send some root samples to a testing laboratory to examine them for the presence of any live nematodes

in the galls. Contact details can be found in the AWRI Research to Practice guide Nematodes: A sampling method for nematode monitoring at www.awri.com.au/wp-content/uploads/nematodes_sample_method.pdf
Monitor your vineyard soil and vine roots from time to time if you have planted an own-rooted cultivar in an infested vineyard.
Contact your nearest NSW DPI office to ask where to send your samples for nematode testing.

Grapevine berry ripening and wine aroma ALAIN DELOIRE, DIRECTOR, NWGIC, WAGGA WAGGA
Optimal maturity of grapes depends on multi-faceted criteria. Several important classes of compounds are biosynthesized during the berry growth period, before and/or after veraison (e.g. aromatic precursors, phenolics, hormones and organic acids), whereas others are provided by roots and/or leaves (e.g. water, minerals and sugar). Several of these compounds change during the ripening stage of the grape berry. These changes do not occur in a highly coordinated fashion; instead, they suggest a series of independently regulated pathways of synthesis. Each pathway is influenced by seasonal climatic factors, vineyard practices, and cultivar. To add to this complexity, each berry within a bunch has its own dynamic of growth and maturation.
The question therefore is how to capture this complexity and to decide on or predict the appropriate harvest dates in relation to wine styles and categories?
How are today’s harvesting decisions made by viticulturists and winemakers? There are several methods:
• harvest according to knowledge of a specific cultivar and vineyard, without any analysis but through visual observations (building up personal experience as a vigneron)
• harvest according to one criterion that requires simple, routine analysis, such as Brix (the most commonly used indicator in the wine industry today)
• harvest according to berry tasting, which can be very subjective. The decision is related mainly to the personal experience and training of the taster.
• harvest by using a series of indicators and appropriate analysis methods. This implies that the necessary apparatus is available on the estate or at an appropriate laboratory nearby. Knowledge in interpreting analytical results to take the appropriate decision is therefore required. The cost per hectare also has to be considered.
• harvest by using new decision-making tools and taking into consideration new scientific results. This implies the ability to access the information, understand and assimilate it, and then implement it successfully by using an extension and adoption process. In addition, the ability to afford this new technology, which may be expensive, has to be considered.
This list is not complete. It is important that those responsible for deciding on a harvest date also acquire the necessary skills and information. Such skills include, for example, being able to interpret the analytical data, to use the analytical tools properly according to a standard protocol, and to sample properly in the first place.
Optimal grape ripeness is defined according to the wine style goal, which in turn is dictated by market demand or by the objective of producing a wine that respects the expression of a typical terroir-related character. (‘Terroir’ refers to a combination of local geography, geology and climate.)
Professionals working within the sector are therefore obliged to accurately characterize the grapes in order to make an informed decision about optimum harvest date; they also need to adapt fermentation and winery practices to obtain a target wine style.
One of the most important and difficult parts of the viticulturist’s and winemaker’s job is to predict the wine style from the berries and the enological process. Classical indicators such as Brix, malic and tartaric acid levels, titratable acidity, and levels of tannins and anthocyanins are strongly related to the perception of the taste of the wine (mouth feel). Therefore, it is also highly useful to be able to predict or predetermine the future wine style, in terms of aroma, from the fruit itself.
Berry ripening, wine flavours, and the production of low alcohol wines are, today, among the priorities of the wine industry worldwide, mainly in the context of climate change (i.e. increases in temperature and evapotranspiration) and scarcity of water.
The harvest-decision-making method that we are calibrating to suit red cultivars in the Australian wine industry uses the concept of berry sugar loading. The method that is being adapted to suit white cultivars uses berry colour evolution.
Berry sugar loading in red cultivarsThe method used to evaluate ripening in red cultivars is based on the fact that, from veraison onwards, the berry aromatic sequence that occurs when sugar per berry reaches a plateau seems to be stable and therefore can be predicted (Figure 3). This aroma sequence consists of fresh, neutral/spicy, mature, and over-ripe or ‘jammy’ stages (Figure 3).

is determined by using optical technologies, as an indicator of berry ripening versus wine aromatic profile. This method is based on an indirect relationship between the evolution of the berry tint angle (according to the HSL model – Hue, Saturation, Luminescence; Figure 5) and the wine sensorial analysis (Table 7). It has potential to be very useful for profiling berry maturation and harvest potential and for selecting the most appropriate harvest dates for white cultivars.
Table 7. Thresholds of berry hue (in degrees) according to the HSL model of colour representation and expected styles of wine for most of the white cultivars. Simplified thresholds (berry colour evolution occurs irrespectively of Brix and titrable acidity) are:
> 80 = green/asparagus/citrus/unripe < 80 and > 70 = tropical/grapefruit/citrus/boxtree < 70 = fermentative/neutral/terpene
Berry hue thresholds (in degrees) Expected wine aromatic profile
> 90 Green/unripe
90–85 Green/asparagus
85–80 Asparagus/citrus
80–75 Asparagus/tropical fruit/grapefruit/citrus
75–70 Tropical fruit
70–65 Fermentative/terpene
65–60 Phenolic/neutral/terpene
For white cultivars, no direct relationship has yet been established between berry colour development from veraison to harvest and Brix and titrable acidity values.
No doubt climate change will influence berry ripening, and this may have repercussions for time of harvest and style of wine produced.
As the world becomes more technologically advanced, more advanced technology is being developed to monitor berry ripening. Such decision-making tools are rapidly being adopted by large estates and co-operatives to enhance their marketing edge. The National Wine and Grape Industry Centre, in collaboration with the Australian Wine Research Institute and other partners, aims to calibrate these tools for the Australian wine industry and to improve their efficiency. The methods presented in this article are not exclusive: new methods or decision-making tools are likely to be developed in parallel with these ones.

However, there is no direct relationship between fruit Brix (i.e. fruit sugar content) or titratable acidity level and the berry aromatic sequence stages (e.g. see Figure 4), meaning that the fresh, neutral/spicy (or pre-ripe), and mature stages can be reached at the same Brix value, although this depends to a certain extent on the individual situation. Thus the berry aromatic sequence model shows that using the Brix value alone cannot help us to predict harvest date and wine style.
Berry colour evolution in white cultivarsBerry colour is a new and important indicator of ripening in white varieties, because a possible relationship exists between berry colour and berry aromatic potential. Carotenoids, which are phyto-protective pigments produced by photosynthesis, are localized in the skin and are considered to be biogenetic precursors of C13-norisoprenoid glycosides. Certain aromas are derived from the degradation of such skin pigments.
A technology for measuring berry skin colour has been developed by the Vivelys Society in France and is currently being used in both the Northern and Southern Hemispheres. The method uses the development of the berry tint angle (berry colour evolution), which

Botrytis fungicide evaluation trialRICHARD HILDER, NSW WINE INDUSTRY ASSOCIATION R&D COMMITTEEMELANIE WECKERT, SENIOR RESEARCH SCIENTIST, NWGIC, WAGGA WAGGA
Because of above-average rainfall in 2011–12, Botrytis infection of mature grapes resulted in them not being harvested in vintages 2011 and 2012. This placed financial strain on producers and caused losses of premium wine.
Rainfall from veraison to harvest is the factor most likely to cause losses from Botrytis infection. Moreover, rain during flowering can cause latent Botrytis to show up as the grapes approach maturity. The incidence of Botrytis is influenced by site selection, canopy management, crop load, vineyard floor management and whether protective spray programs are used.
To reduce the incidence of Botrytis, the NSW Wine Industry Association R&D Committee nominated trials and extension as a number 1 priority. Funding from the GWRDC Innovative Committee has been granted to implement these for the 2013 and 2014 seasons.
Since 2011, a number of Hunter Valley growers have adopted the use of products containing the fungus Trichoderma for Botrytis control. This natural predator of Botrytis is now available in sprays for Botrytis suppression and can be used as an alternative to conventional synthetic chemicals registered for Botrytis control. Anecdotally, these growers have had encouraging results using Trichoderma sprays in accordance with the manufacturer’s recommended protocols rates and timing.
The Trichoderma that is present within the grape bunches consumes Botrytis, but it is annihilated by other Botrytis fungicides. No doubt this partly explains why organic vineyards where the Trichoderma fungi are not endangered often have lower rates of Botrytis infection, even when the prevailing conditions favour its occurrence.
With the help of Dr Greg Dunn and Dr Melanie Weckert at NWGIC Wagga Wagga, a Botrytis Fungicide Trial was designed to compare an organic botrytis spray program with a conventional Botrytis spray program.
DesignThe treatments (30 vines per treatment) were:
T1: Conventional Botrytis spray control
T2: Trichoderma products (Colonizer® and Antagonizer®)
T3: Potassium salts of fatty acids (i.e. soap salts; Ecoprotector®)
T4: Control (no Botrytis fungicides).
The experiment was conducted in a 4.35-ha, 12-year-old block of Chardonnay at Glenesk Vineyard at Denman in the Upper Hunter Valley of NSW.
ApplicationFor each treatment we used a separate dedicated hand-spraying knapsack. The conventional spray treatment was applied by knapsack at the same time as it was applied to the rest of the Chardonnay in the block.
Colonizer® (Trichoderma koningii) was applied at >20% capfall (on 28 September 2012), with a second spray at >80% capfall on 6 October. Care was taken to ensure that fungicides for powdery mildew and downy mildew were not applied to the whole block within 7 days either side of applying the Trichoderma sprays.
As a continuation of the Trichoderma treatment, Antagonizer® (Trichoderma harzianum) was applied after veraison on 28 December, and again after rain on 24 January in the New Year (2013).
Ecoprotector® was applied at <5% capfall, at pre-bunch closure, and after veraison on 28 December 2012 and on 24 January 2013.
The block was picked on 7 February 2113 at >12.8 Baumé or 23° Brix.
MeasurementsMethod of monitoring for latent Botrytis infectionThe treated plots were monitored for Botrytis infection of the leaves before flowering: the presence of infection in the leaves could increase the spore load, especially if spores became trapped within a bunch.
We assessed the four middle vines of the middle row of each treatment (i.e. row 2, vines 4, 5, 6, 7 of 10 treated vines).

One week after the 80% capfall spray, four inflorescences per vine from each treatment were randomly selected, secured in four separate ziplock plastic bags, and despatched to Dr Weckert for microscopy.
At inspection of the trial on 25 January 2013 there was no visible evidence of Botrytis infection in any of the treatment plots.
On 4 February, 3 days before harvest and after 117 mm of rain had fallen in the previous 3 days, the vines were inspected again for Botrytis rot.
A day later, three bunches from each treatment plot were randomly selected, secured in separate ziplock plastic bags, and then placed on a bench in the vineyard’s recreation room for later observation of Botrytis development.
Bunches were collected only from treatments T2, T3 and T4 at harvest; they were sent to Dr Weckert for analysis.
Laboratory resultsInfection on inflorescencesFour inflorescences (immature bunches) were collected from each of six replicates of every treatment 1 week after 80% capfall and sent to Melanie Weckert for fungal analysis.
The inflorescences were frozen for 2 weeks to disrupt the plant cells. The frozen inflorescences were thawed, placed in ziplock plastic bags and incubated for 2 weeks at room temperature.
The inflorescences were then weighed, placed in phosphate-buffered saline (pH 7), and shaken well to dislodge most microbes from their surfaces. The phosphate-buffered saline was serially diluted a number of times, and the diluted washes were spread over DRBC (dichloran rose-bengal chloramphenicol) and Botrytis Selective Medium (BSM) and incubated at 25°C in darkness. After 5 days, Melanie counted all of the colonies at the 10–3 and 10–5 dilutions. BSM agar turns brown around Botrytis colonies. As none of the fungal colonies was surrounded by a brown zone, this indicated that there was no Botrytis on the inflorescences.
This meant that it was highly unlikely that there was any latent infection at that stage (Table 8).

As expected, inflorescences from treatment T2 (Trichoderma Colonizer® and Antagonizer® products) contained significantly higher levels of Trichoderma spp., and higher percentages of the total fungi were Trichoderma spp. (Table 8).
Infection on berries at harvestBunches were collected only from treatments T2, T3 and T4 at harvest. Bunches were frozen at –20°C for 7 days before incubation.
Freezing bunches terminates host resistance and promotes development of the fungal pathogen within the plant tissues, giving a more realistic estimation of bunch rot severity and incidence under the most adverse conditions.
After being frozen, these bunches were incubated at 25ºC for 10 days in ziplock plastic bags containing moist paper towels to increase humidity.
Bunches were scored for coverage of Botrytis bunch rot (i.e. severity). The incidence was 100% (i.e. every bunch had some Botrytis bunch rot). The percentage rot per bunch was significantly decreased by the T2 Trichoderma treatments (43% decrease) and by the T3 Ecoprotector® treatment (97% decrease), although the difference between these two treatments was not statistically significant (Table 9).
Conclusions from laboratory investigationsThere was no latent Botrytis cinerea in the inflorescences. The combined Colonizer®–Antagonizer® Trichoderma

treatment successfully increased Trichoderma spp. colonisation of the inflorescences.
Both the Trichoderma and the Ecoprotector® treatment decreased colonisation of grape bunches by Botrytis cinerea later in the season, although there was no statistically significant difference in the effectiveness of these two treatments.
Results of field observations Severity and incidence of BotrytisTable 10 shows the severity and incidence of Botrytis as assessed in the field for each treatment on 4 February (3 days before harvest and after 117 mm of rain had fallen in the previous 3 days).
Table 11 shows the severity of Botrytis infection in the four treatment groups after three bunches from each had been left in ziplock bags on the recreation room benches for 7 days.
Unlike with the method used to obtain the results in Table 9, these bunches were not frozen before incubation; this explained the lesser degree of Botrytis severity in Table 11 than in Table 9.
Season 1 final conclusionsApart from a few light showers during flowering, rainfall was not a predisposing factor for Botrytis infection until the rain events beginning on 20 January 2013.
The laboratory results indicated that the light rain during flowering at the trial site did not cause latent infection.

floor management, and the use of protective spray programs. Attention to these details helps immensely in reducing losses from Botrytis.
This trial will be continued next season. As a result of this year’s findings we plan to introduce several extra treatments, including a combination of Trichoderma and Ecoprotector® together in one program.
These products cannot be tank mixed, and the Trichoderma products need to be sprayed at least 7 days after the Ecoprotector® spray so as not to kill the living spores.
On the basis of our preliminary results, a suggested combination program would be:
1. Ecoprotector® at 5% to 10% capfall
2. Colonizer® at 80% capfall
3. Ecoprotector® at pre-bunch closure
4. Antagonizer® at veraison
5. Ecoprotector® up to 14 days before harvest (before the 14-day withholding period)
6. Antagonizer® if required because of rain (Antagonizer® has a 1-day withholding period).

At visual inspection of the trial site on 25 January 2013 there was no evidence of Botrytis infection in any of the treatment plots.
However, the 117 mm of rain over a 3-day period before harvest caused Botrytis infection in all treatment plots before the harvest (on 7 February), although the entire trial block was harvested within the winery tolerance of <4% Botrytis incidence.
Recommendations for the future: looking forwardThe severity and incidence of Botrytis are influenced by site selection, canopy management, crop load, vineyard

Trial of alternative varieties reworked on Chardonnay in the MurrayGREGORY MOULDS, SENIOR LAND SERVICES OFFICER – HORTICULTURE, LOCAL LAND SERVICES, BURONGA APRIL WINCKEL, MURRAY VALLEY WINEGROWERS’ INCORPORATED, MILDURA
‘‘Alternative varieties’ has been a buzz word in the industry, but how climatically or economically suitable are these alternatives?
This trial investigated the best way to change over to an alternative variety. It also compared the performances of a range of alternative varieties with those of traditional varieties in the Murray Valley.
The trialA trial was established at the Dareton Research Institute, near Mildura, to demonstrate the suitability of alternative varieties to this region and evaluate two methods of reworking that can be used to establish the new varieties on existing vines.
The trial site was 0.6 ha planted to Chardonnay on Ramsey in 1995. The block also contained two rows of Chardonnay on six different rootstocks used in a previous trial, giving us the opportunity to examine the effect of rootstock on the performance of the alternative varieties we tested.
The vines were planted in 3.3-m rows with 2.4-m vine spacing on a two-wire vertical trellis, and they were box-pruned.
The soil was a sandy loam varying in depth from 70 to 105 cm, with an active root depth of 40 to 75 cm. The vines were irrigated with drippers spaced every 50 cm. Nutrition was applied by fertigation and a routine foliar program.
Two methods of reworking were used: grafting a bud of the new variety into the original rootstock (mostly Ramsey) and grafting a bud of a new variety into the Chardonnay trunk (see photos). The losses were highest in vines reworked into the rootstock.
Grafting observations• Savagnin and Montepulciano had the greatest
number of vines that had to be re-budded because of graft failure.
• Pinot Gris, Lagrein, Pinotage, Montepulciano and Tannat suffered the most canopy roll in the first two seasons of establishment and required the most training during the season.
• In the first season, the yields of Muscat Gordo, Arneis, Pinot Gris and Montepulciano grafted into the Ramsey rootstock were less than 50% of those of the same varieties bud-grafted into the Chardonnay trunk.

Varietal growth and maturity observationsSixteen varieties were selected for establishment (eight reds and eight whites). The varieties, which included standard varieties for comparison, were:
• White grapes: Arneis, Fiano, Vermentino, Sauvignon Blanc, Savagnin (formally Albarino), Viognier, and Muscat Gordo Blanco
• Red grapes: Pinot Gris, Graciano, Lagrein, Montepulciano, Pinotage, Tannat, Tempranillo, Shiraz and Cabernet Sauvignon.
Below is a summary of the alternative varieties tested.
Arneis
Arneis has erect growth and high vigour, with thin spindly shoots and medium-sized leaves. This variety grew well after a slow start in the first season. The fruit was spread evenly throughout the canopy and was easy to harvest. Bunches were compact, and yield was in the high range and better than expected. Bunches were very susceptible to rot damage.

FianoThis variety is erect and highly vigorous, with long shoots and large leaves. It appeared to be well suited to the Murray Valley climate. Some vines showed hen and chicken (mixed berry size) and also a second crop on the lateral shoots. Fiano had loose bunches with small berries of consistent quality and good disease resistance.

Vermentino Vermentino is an erect, highly vigorous variety producing long shoots with large wavy leaves. It appears well suited to Murray Valley climatic conditions. The vines have grown well in the very hot spring and summer. In our trials the variety produced the highest yield and the largest bunches of all varieties in both seasons.

Tannat This variety is slightly erect and highly vigorous, with long canes and medium to large leathery leaves that roll backwards. Tannat was the most difficult to train and develop a full canopy owing to its tendency to roll. Problems of excessive vigour, vine death and low yield may indicate that Ramsey is not a suitable rootstock for Tannat.

Production yieldsThe first-year yield was drastically reduced by botrytis infection following abnormal mid-summer rain.
On the basis of the second year’s results (2011–12, Figure 6), varieties were categorised into low (purple), medium (blue) and high (orange) -yielding.
The lowest-yielding varieties were Pinot Gris, Tannat and Montepulciano. In general, the yields obtained would be considered lower than district averages for similar red varieties.
Tannat and Pinot Gris produced low yields owing to poor canopy development, and they seemed to suffer from waterlogging of the soil and the root zone.
The medium-yielding varieties included Fiano and Tempranillo; they produced yields comparable to that of Cabernet Sauvignon. There was no reduction in Fiano yield through bunch rot.
Of the remaining, high-yielding varieties, Graciano and Vermentino had the lowest percentages of fruit with sunburn or fruit rot.
RootstocksIn addition to being planted on Ramsey, Pinot Gris and Fiano were reworked into the trunks on the following rootstocks: Ramsey, Schwarzmann, Ruggeri 140, K51-40 and SO4.

Our observations revealed that Fiano was a vigorous variety. Careful consideration is therefore required in selecting a suitable rootstock for this highly vigorous variety. In our early results the Fiano yield did not differ significantly among the different rootstock selections (see Figure 7).
Pinot Gris yield differed by 88% (Figure 8) between the best and worst rootstock combinations, suggesting that a highly vigorous rootstock is important for this variety.
Not enough vines were measured to reliably assess rootstock combinations, so rootstock choices should not be based on these early results.
Some suggestions to consider• Reworking of alternative varieties directly into the
Chardonnay vines on the Ramsey rootstock has been successful.
• Muscat Gordo, Tannat, Montepulciano and Shiraz reworked directly onto the Ramsey rootstock performed poorly.
• Cropping levels returned two seasons after the reworking.
• From observations over the past two seasons we can make the following conclusions:
— Fiano, Vermentino and Graciano are the varieties most suited to the area. Graciano has performed very well and is a good prospect for the Murray Valley.
— Fiano appears to be suitable for use with lower vigour rootstocks, although more work will be required to confirm this observation.
— Graciano required more water applications from veraison till harvest to maintain fresh fruit in good physical state.
— Sauvignon Blanc, Savagnin, Arneis, Lagrein and Tempranillo are considered less suitable because of the high costs associated with managing vegetative growth and the susceptibility of these varieties to bunch rots.

Grape marc mulching in Riverina vineyardsJASON CAPPELLO, DEVELOPMENT OFFICER VITICULTURE, NSW DPI, GRIFFITH
IntroductionGrape growers in the Riverina are wanting to know the benefits and impacts of applying grape marc to their vineyards. To answer this question a demonstration trial was established at the NSW DPI Hanwood vineyard, near Griffith. The aim of the trial is examine soil chemical properties, vine health, grape and wine composition and grape yield to find out what happens when grape marc is used as mulch.
Trial background• The Riverina has over 70 000 t of aged grape marc
available for use. In other regions across South Australia, grape marc is used annually to improve soil conditions.
• Locally, because of previous negative experiences and supply problems, vineyards have not favoured the regular use of grape marc, and hence there are only a small number of vineyards using it.
• This trial tested the use of grape marc applied beneath the vine in a drip-irrigated vineyard in the Riverina.
The treatmentsSix treatments were applied at the NSW DPI Hanwood vineyard, using Shiraz PT23 on Ramsey rootstock:
• Treatment 1: Control, i.e. no treatment to vines
• Treatment 2: Grape marc applied to the soil surface at about 100 t/ha to achieve a mulch layer between 3 and 4 centimetres thick, with mixed NPK fertiliser added at 250 kg/ha applied before the grape marc
• Treatment 3: Grape marc applied to the soil surface at about 100 t/ha to achieve a mulch layer between 3 and 4 centimetres thick
• Treatment 4: Grape marc applied to the soil surface at about 50 t/ha to achieve a half-rate mulch layer
• Treatment 5: Grape marc with added chicken manure or litter applied to the soil surface at about 50 t/ha
• Treatment 6: Mixed NPK fertiliser applied to the soil surface at 250 kg/ha, with no grape marc applied.
Results from the first seasonSoil moisture levelsWe monitored soil moisture with an Enviroscan Sentek system. The monitoring showed an increase in soil moisture retention under the thick grape-marc mulch (treatments 2 and 3).
Soil temperature levelsTemperature sensors were installed in the soil to measure temperature within the top 10 cm of the soil, based on past mulching projects.
All of the data has not yet been analysed, but examination of the mid-season data revealed a reduction in soil temperature in treatments 2 and 3 (Table 12).Table 12. Soil temperature analysis 10 cm below the soil surface from 1 October 2012 to 18 December 2012 at Hanwood

The soil temperature results showed that there was a buffering effect in the soil covered thickly with grape marc mulch (treatments 2 and 3). Mulch insulates the soil surface, regulating the temperature in the root zone (Figure 9) so that roots are able to survive better in the top 200 mm of soil. Mulch also improves soil structure by adding organic matter and increases water infiltration (Compost for Soils, 2011).

Nutrient analysis of treatmentsTable 13 shows the nutrients in the various products used in the trial.
Petiole and soil chemical analysisPetiole samples were collected at 80% capfall and sent away for analysis. We found no statistically significant differences among treatments.
Soil samples were collected from the plots in September 2012, before any of the treatment applications. We found no statistically significant differences among treatments. Soil samples will be collected again, in September 2013, to view changes in the nutrient levels within the soil over the first 12 months since application of the treatments.
Maturity and yield analysisSamples consisted of 10 bunches selected randomly from each plot, with five bunches taken on the western side of the vine and five bunches taken on the eastern side.
Baumé. We tracked fruit maturity from 20 January 2013 (average 10.3 Baumé) until 26 February 2013 (average 13.8 Baumé). At harvest 1 week later, on 4 March 2013, the average Baumé value was 14.5 across all the treatments and there were no significant differences. Figure 10 shows the average Baumé changes between sample dates across all replicated plots in each treatment.
Berry juice pH. A decline in berry pH occurred in week 4 (15 February 2013) in most treatments, with the exception of treatment 5. A subsequent increase the following week was observed in all treatments. Figure 11 shows the average pH change between sample dates across all replicated plots in each treatment.

All analyses are by dry weight. Samples were dried at 40°C for 24 hours before being finely ground.2. Samples were digested on a hotblock digestor by using Aqua Regia acid and then analysed by ICP-MS.3. Carbon, nitrogen and sulfur were quantified with an LECO CNS2000 analyser.4. mg/kg = ppm; 1% = 10,000 ppm* There were slight increases in nitrogen and sulfur levels due to ammonium sulfate fertiliser runoff from a nearby stockpile.
Titratable acidity. Titratable acidity declined over time across the sampling period. No treatment effects were observed (Figure 12).
Bunch weight. Bunch weight rose between the first two sampling dates, declined for 3 weeks and then increased after this, although it did not recover to week 2 levels. When averaged across dates, bunch weight for treatment 1 was lower than those for all the other treatments, and bunch weight for treatment 6 was lower than for treatments 5 and 3 (Figure 13).

Berry weight. There were no treatment effects on berry weight, which declined over time (Figure 14). Berry weight measurements were not obtained on 30 January 2013 or 15 February 2013.
Anthocyanin colour (mg/g berry weight). There were significant effects of both treatment and date. Treatment 6 gave the highest colour averaged over all dates (Figure 15). Measurements were not obtained for anthocyanin colour on 30 January 2013 or 15 February 2013.
For the analyses we used the wet chemistry method in the Australian Wine Research Institute 2009 factsheet Measuring total anthocyanins (colour) in red grape berries (see www.awri.com.au/wp-content/uploads/anthocyanins_fact_sheet.pdf ).
Harvest yield. ANOVA analysis indicated that on the basis of this one year’s worth of data we do not have enough evidence to be 95% confident of the treatment differences. Further investigation in future years of the variability of the different treatments is needed to confirm a difference in harvest yield between treatment 6 and treatment 3.
Figure 16 shows the combined yields of the harvested plots for each treatment and the estimated yields per hectare.
Wine analysis and potassium levels. Small-lot wines were made from the grapes from all treatments. This was done at the NWGIC’s experimental winery at Wagga Wagga. The wines were made by collecting all the fruit harvested from each replicate plot of the treatment and then crushing them to obtain three replicates of 60-L wine batches.

At the time of bottling a final analysis was done to observe any chemical differences between the wines (Table 14). Also a potassium ion concentration analysis was done to determine whether the first year of using the grape marc in the vineyard had caused any elevation in potassium ion concentrations. Potassium ion concentrations did not differ greatly from those of commercial wines.

Undervine weed managementWeeds have become established under all treatments of the trial. In those plots where thicker grape marc has been applied, the weed count has been reduced to one or two plants per metre, whereas in plots with exposed soil there are more than 10 plants per metre.
Costing for applications as at September 2012The delivery and application cost for using the grape march in this project was estimated at $15/tonne (freight was $10/t and spreader/loader hire was $5/tonne), not including labour and tractor-running costs.
Hire rates generally work out at about $300/day for a spreader. Loader fees may be included or additional to the spreader hire.
Freight can cost between $5 and $10 a tonne, depending on the distance and the quantity of material to be moved.
The loading fee charged by Tarac Technologies near Griffith, the supplier of the marc, is about $2 or $3 a tonne to recover operational costs.
Other information of interestTarac Technologies at Beelbangera, near Griffith, has the only major distillation processing facility in NSW and presently has a large quantity of aged marc that could be put to use.
Work done in Western Australia by the Grape and Wine Research and Development Corporation’s (GWRDC’s) regional Grassroots Solutions program has resulted in the development of updated information guides on composts and mulching for industry. To view these documents, visit www.perthregionnrm.com/media/57989/grapevine_nutrition_amended.pdf (Managing grapevine nutrition and vineyard soil health) or www.perthregionnrm.com/media/65488/utilising_mulch_and_composts_in_vineyards.pdf (The use of mulch and compost in vineyards).

Take-home message and things to think about before using mulches undervine• Compared with the results in bare earth soil, using
grape marc mulch improved soil moisture retention under thick levels of mulch and reduced soil temperature fluctuation within the top 10 cm of the soil.
• Greater amounts of fine vine roots were observed with the use of grape marc mulch than with bare earth soil.
• It is important to have a clean soil free from weeds and prunings before you apply thick layers of organic material: fresh prunings can take root and need to be sprayed out with herbicide.
• Ensure that the source material has been subjected to a recent nutrient analysis test. This allows you to identify whether there are any issues with the material, such as a high pH or carbon to nitrogen (C:N) ratio.
• If the organic material has a high C:N ratio (>25:1), add a nitrogen fertiliser before you apply the organic material to the soil. This will reduce the drawdown of soil nitrogen stocks.
• It may be more economical to use high rates of mulch to target poorer areas of a vineyard (i.e. poorly designed irrigation setups or lighter soil types in a vineyard patch) rather than the whole vineyard.
• Consider using pre-emergent herbicides before marc application to improve weed management, unless you are applying thick mulch layers (between 5 and 7 cm thick).

IntroductionGrape growers would like to have more detailed information on the optimal timing and rate of fertiliser applications in vineyards.
We have established a trial in the Murray Valley to address this need through field observations of root growth under different conditions and with different varieties of wine grapes.
Periodicity of root growthGrapevine roots do more than just anchor the vines. Roots absorb water and minerals, store carbohydrates and nitrogen, and produce hormones to control plant development (Comas et al. 2010).
The study of root growth is difficult, as roots are not easily measured or observed without damaging the environment in which they grow. Most studies have used root chambers to examine the pattern of root growth over the growing season. The perennial root system develops over a period of 5 to 7 years after planting, and the morphology and density of the roots that develop depend on the soil structure, depth and moisture and also on the rootstock if the variety is grafted.
New roots are produced on a yearly or seasonal basis from perennial structural roots: they are white when they are growing and become brown over the season. The new root system formed yearly, namely the fine roots, is very important for vine function. The number of fine roots affects vine water status (water adsorption) and vine mineral balance (mineral adsorption). The growth pattern of the fine roots has been determined by numerous studies (e.g. Freeman and Smart 1976; Van Zyl 1984, 1988) and is shown in Figure 17. Studies of root production on Chardonnay and Shiraz at Wagga Wagga
have indicated that the major flush of root growth occurs at about the time of flowering (Holzapfel et al. 2009).
Root growth appears to be regulated by soil temperature, moisture and mineral composition (‘exogenous’ factors) and carbohydrate and nitrogen reserves (‘endogenous’ factors).
Under different climatic conditions and with different soil structures, moisture (or irrigation management) levels, temperatures and mineral compositions, the periodicity of root growth could vary. The structure of the canopy could play a role as well.
Root growth is greatest when the nutrient demand of vines is at its highest (Holzapfel et al. 2012). This suggests that the most effective time to apply nutrients to improve grape production is when the roots are growing. Actively growing roots are white, and when they are this colour they are most active in nutrient uptake.
Why study root growth?Studying root growth in the Murray Valley region will help us to understand how the conditions at individual sites interact with the cultivar and the rootstock to influence the fine root growth profile. This can help us to make recommendations on soil management (including cover crop choice and the need for mulching), irrigation and fertilisation (e.g. whether to choose a soil or foliar fertiliser).
Measuring root growth in root chambersA number of options are available to measure root growth; they include using minirhizotrons, digging soil pits, sampling roots, planting into clear pots, digging up whole plants and using root chambers.
A root chamber is a non-destructive means of monitoring root growth (Anderson et al. 2003). The advantage of root chambers is that they require no specialised equipment. However, the limitations are that their large size makes them difficult to install, and at shallow depths the number of roots tends to be underestimated (Glinski et al. 1993). Because in this study we are interested in observing the timing of root growth, not the root density, we did not regard this latter characteristic as an issue.
Root chambers and locationsA root chamber is a box with perspex and plastic sides; it has no bottom and a solid wooden or metal lid. The chambers are installed within the vine row midway between two vines.

We selected six sites to cover the two main types of irrigation and three grape varieties. The sites are:
• Chardonnay grafted on Ramsey under drip irrigation and with no cover crop
• Chardonnay grafted on Ruggeri 140 under low-level sprinklers and with an active cover crop and mulch
• Shiraz (non-grafted) under drip irrigation and with a cover crop
• Shiraz (non-grafted) under low-level sprinklers and with a cover crop
• Cabernet Sauvignon (grafted on Schwarzmann) under drip irrigation and in a light soil
• Cabernet Sauvignon (grafted on Schwarzmann) under drip irrigation and in a heavy soil.
First-season resultsRoots were photographed from the start of the growing season in August, through to October, and then again after harvest until May, when root darkening indicated that growth had ceased.
In addition, soil temperatures were recorded with loggers placed in the base of each root chamber to evaluate whether there was a correlation between local soil temperature conditions and the timing of root growth.
TemperatureAverage air temperatures fluctuated greatly over the season, whereas the soil temperature was more stable. Figure 18 compares the soil temperature averaged over all root chambers with the air temperature.
One study of Thompson seedless grapes has shown that roots grow at soil temperatures of 15°C to 30°C (Callejas et al. 2009). We, too, observed that root growth stopped once the soil temperature dropped below 15°C.
Soil temperature varied only slightly among root chambers. This variation may have been due to differences in the position of the data logger, the location of the chamber, the vineyard soil type or vineyard management techniques. In the case of Cabernet Sauvignon drip-irrigated in a heavy soil, the soil temperature was consistently cooler during the season
(Figure 19). The soil was generally warmest in the case of Shiraz irrigated by drip and Cabernet Sauvignon drip-irrigated in sandy (i.e. light) soil.

Root growth timingThe flush of root growth, as shown by the growth of fine white roots, depend on various parameters, and the results of scientific studies vary (Van Zyl 1988; Callejas et al. 2009). Roots continue to grow throughout the year but at a slower rate during the winter.
The root chambers were installed late in August and therefore had been in the ground only for a short time before budburst. At the trial sites, budburst started on about 3 September for Chardonnay, on 12 September for Shiraz, and not until 21 September for Cabernet Sauvignon, and there was no root growth evident. In the Riverina, a few white roots have been seen before budburst on own-rooted Shiraz, but not on Chardonnay grafted on Ramsey; Cabernet Sauvignon was not included in that study (Holzapfel et al. 2012). In future studies it would be useful to see the canes bleeding (i.e. losing water through pruning wounds; this indicates that the root system is pumping water even if there is no root growth) so as to differentiate between root growth and root functioning.
In our study, flowering occurred on 23 October for Chardonnay, 30 October for Shiraz and 5 November for Cabernet Sauvignon, by which time there was root activity in all of the root chambers (see photos). Root activity ceased close to fruit set.
Post-harvest roots began to actively grow (see photos) in Shiraz and Cabernet Sauvignon but not in Chardonnay. Shiraz roots continued to grow for longer than did those of the other two varieties. These results are the reverse of
the 2007–08 Riverina study results, in which white roots were observed on Chardonnay but not Shiraz during the post-harvest period (Holzapfel et al. 2012).
Soil typeSoil hardness strongly affects root growth. Plants growing in hard soil that is very loose have poorly developed and often stunted roots (Bassoi et al. 2003). In coarse-textured soils the root density is low in the top 20 cm, possibly because of soil moisture availability issues (Smart et al. 2006).
In the first season of our project the roots in the lighter soils displayed more growth than those in the heavier soils; moreover, the soil temperatures were higher in the former.
First-year challengesThe initial installation required us to dig a hole for placement of the root chamber, thus causing root damage. Because of differences in root density, soil type and digging accuracy, the extent of root damage varied among sites. This problem will not be an issue in future observations because the chambers will already be in place.
PerspectivesAs new research continues to be done, it appears that our current understanding of root activity is incomplete and that root activity is far from simple. Climatic region and seasonal variation (Comas et al. 2010) have substantial influences on root growth and functioning, and new fine root growth vary according to soil type, structure, moisture, pH, temperature and mineral composition.
Continued examination of root growth is needed before recommendations can be made about the best time to apply nutrients. We intend to do further work using the root chambers this season (2013–14). Observations will start before budburst, at which time we will also observe the vines for cane bleeding.

Growing grapes for export wine?… choose the right chemical
Governments around the world set limits for the amount of residue of a fungicide, insecticide or herbicide that is legally allowed in a food, such as grapes or wine. These limits for agrochemicals are commonly referred to as MRLs (maximum residue limits), and for Australia they are listed in the Australian New Zealand Food Standards Code.
Over the past year, Australian wineries have exported wine worth more than $1.85 billion, mostly to countries that have MRLs vastly different to, and sometimes lower than, those set by our own government. In fact, some chemicals commonly used by Australian grapegrowers do not have MRLs in some of our major export markets. Often this is because grapes are not grown commercially in these countries and, therefore, there is no need to register products for use on grapes. As a result no MRL is set, which means that the importing country will either not allow any detectable residue of the agrochemical in wine, or only permit ‘safe’ amounts of it.
To ensure that wine meets these requirements, it is necessary to restrict the application of certain chemicals or to avoid their use altogether. Since 1991, some wineries have provided their grapegrowers with a list of recommended fungicides and insecticides and the associated ‘export harvest interval’ (the minimum number of days before the last application and harvest). The export harvest interval is sometimes much longer than the withholding period stated on the chemical label, and it has been calculated to minimise the likelihood of residues affecting fermentation, affecting sales of the wine and to reduce the exposure of the public to pesticides.
The following tables list the preferred agrochemicals for use in the production of grapes for export wine, and any restriction on their use, for the 2013/2014 season. Some biological control agents are also listed. The recommendations have been developed to satisfy the lowest MRL for any of Australia’s major wine markets after considering available data on the persistence of the chemical, both on grapes and through winemaking. Many of these data were gathered as a result of a large, multi-agency research effort, funded by the Grape and Wine Research and Development Corporation and the Dried Fruits Research and Development Council. A list of current MRLs and supporting information can be obtained by visiting the AWRI’s website: www.awri.com.au, or by contacting Marcel Essling on telephone (08) 8313 6600.

AWRI Agrochemical search app and online search facility The AWRI agrochemicals online search facility and agrochemcial search app allows the user to rapidly access information contained in the current ‘Agrochemicals registered for use in Australian viticulture’ booklet (often called the Dog Book). These tools also contain additional information derived from the AWRI database i.e. they allow the user to search for products registered for use on targets that are not listed in the Agrochemical booklet. Visit www.awri.com.au/agrochemicals/ or scan the QR code below to download the app.
Frequently asked questions Why does The Australian Wine Research Institute recommend that the application of some products (for example Scala) be restricted to before 80% capfall? The recommendations in the tables have been developed to satisfy the lowest maximum residue limit (MRL) for any of Australia’s major wine markets after considering available data on the persistence of the agrochemical, both on grapes and through winemaking.
In the case of Scala (pyrimethanil), it is known that if it is sprayed onto grapes after 80% capfall, residues might be detectable in the resultant wine. Some of the markets to which Australia exports wine have a very low MRL for pyrimethanil, or alternatively, have not announced their position on the course of action they would take if pyrimethanil was detected in wine. To ensure that Australian wine meets MRLs set by all of these markets, the 80% capfall restriction is suggested.
Are there exceptions to these restrictions? Yes. Products may be used closer to harvest than the suggested restriction period in consultation with the winery/grape purchaser.
A winery may choose to ignore the restriction if the wine made from the grapes will be sold in Australia alone, or to an export market that has an MRL greater than the expected residue or if the market otherwise permits residues of the agrochemical. In this case, the label withholding period is the minimum delay that should be observed between spraying the grapes and harvest.
Can I use a product that is not listed? Yes. Provided that it is in consultation with your winery and used according to the label specifications.

Important points
• Ask your winery if they have specific chemical recommendations. These might differ from the recommendations suggested below.
• Grapevine growth-stage can be variable across a block. When assessing grapevine phenology for the purpose of applying agrochemicals, base the assessment on the most advanced vines in the block to minimise the possibility of residues at harvest.
• When spraying, ensure that the amount of chemical applied never exceeds the rate specified on the manufacturer’s label (unless otherwise specified).
• If you are unable to keep to these recommendations, or if you need to spray closer than 30 days before harvest, contact your winery or The Australian Wine Research Institute for advice.
• Avoid spraying some types of foliar fertilisers closer than 60 days before harvest, as wine quality might be affected.
• Always read the label on the chemical container. The products mentioned in the table might not necessarily be registered for use in your State.
• Keep a record of agrochemical applications. Some wineries might not accept delivery of grapes without receipt of a signed spray diary from the producer. An industry accepted spray diary template can be downloaded from the AWRI agrochemical website www.awri.com.au/agrochemicals/
• These recommendations have been developed as a general guide and assume that the wine will be sent to a range of overseas markets, each with differing MRLs. If you only sell wine in Australia, or to only a few countries, contact The Australian Wine Research Institute to discuss how the recommendations might differ. We can also provide advice regarding the persistence of a chemical on grapes or through winemaking, and MRLs for most major export destinations.

Agrochemicals registered for use in Australian viticulture
The following products are registered by the Australian Pesticides and Veterinary Medicines Authority for use in wine grape production in Australia. Always read the label on the chemical container as the products listed in the table might not necessarily be registered for use in your State.
To avoid the development of chemical resistance, it is necessary to know how the product works. Most chemicals have been allocated an ‘activity group’ based on their mode of action. The activity group appears on the product label as a number (or letter and number) for fungicides, a letter for herbicides and a number and letter or only a letter in the case of insecticides and miticides. Sometimes the resistance management strategy is also shown on the label. Management strategies to avoid the development of fungicide resistance have been published by CropLife Australia, and are described on page 19. More information regarding activity groups can be found on the CropLife Australia website: www.croplifeaustralia.org.au
In the past, the export restriction on use for many of the insecticides listed in the table below has not been provided. Due to international pressures, the use of agrochemicals belonging to chemical groups such as the organophosphates and carbamates is not encouraged. The recommended restriction on use for all 1A, 1B, 2B and 4A insecticides listed in this booklet is ‘Use no later than 80% capfall’. In addition, it is recommended that any 3A insecticides that are not restricted to use during dormancy only (label withholding period), should not be used later than 80% capfall. However, it is essential that you contact your winery/grape purchaser prior to the application of any 1A, 1B, 2B, 3A or 4A insecticide.
The CropLife resistance management strategies on page 20 are a guide only and do not endorse particular products, groups of products or cultural methods in terms of their performance. Always follow the product label for specific use instructions. While all effort has been taken with the information supplied in this document no responsibility, actual or implied, is taken for the day to day accuracy of product or active constituent specific information. Readers should check with the Australian regulator’s (APVMA) product database for contemporary information on products and actives. The database can be sourced through www.apvma.gov.au. The information given in the resistance management strategies is provided in good faith and without any liability for loss or damage suffered as a result of its application and use.

Chemical resistance management strategies
What is 'chemical resistance'? Chemical resistance is the inherited ability of an organism, be it a disease, weed or insect to survive doses of an agrochemical that would normally control it. Resistance may develop after frequent use of one chemical, or chemicals from the same activity group. Incorrect chemical use such as under or over dosing or application at the wrong time in the life cycle of the target can also promote resistance.
How does resistance develop? Any population might contain a very small number of individuals which are naturally able to survive the application of a particular chemical. If the same chemical, or chemicals from the same activity group are used repeatedly, and exclusively, the susceptible individuals continue to be removed, and those with natural resistance survive and multiply to essentially dominate the population. The chemistry then ‘fails’ in the field.
It has been observed in vineyards that despite several herbicides being used over a season, they are often applied at the same time each season. As such, the weed species peculiar to that time are treated with the same herbicide each year, therefore promoting resistance.
Resistance countering measures Manage unwanted pathogens, weeds and insects using non-chemical means when possible.
When using chemicals, get the most out of them by: timing them to when the target is most susceptible; using the correct dose; adding suitable adjuvants; and, applying when the conditions are right.
Minimise chemical selection pressure by not overusing chemicals from the same activity group.
CropLife Australia maintains Resistance Management Strategies for fungicides, insecticides and herbicides. These are available at www.croplifeaustralia.org.au.
Fungicide resistance status Resistance to fungicides is a serious problem worldwide and Australia has not been spared. Resistance to many of the commonly used fungicides now exists.
CropLife Australia incorporates two initiatives in fungicide resistance management which ensures the best control with least risk of developing resistance. These are:
1. All fungicides have been classified by activity group, which appears as a number or letter and number code on the fungicide product label; and
2. Strategies have been developed for the use of fungicides in crops where resistance by a particular organism is already evident or considered a risk. See following page.
The advice given in the CropLife strategies is valid at the time of going to print. Current versions of the strategy are available from the CropLife Australia website: www.croplifeaustralia.org.au.

Grey mould (Botrytis bunch rot)
Fungicide activity groups: Group 2 (dicarboximide); Group 9 (anilinopyrimidine); Group 12 (phenylpyrroles); Group 17 (hydroxyanilide); Group 7 (carboxamide)
1. If three or fewer bunch rot sprays are applied in a season, use no more than one spray from the same fungicide group during the season, for any Group 2 or 9 (including combinations with Group 12), Group 17 or 7 fungicides.
2. If four or more bunch rot sprays are applied in a season, use no more than two sprays from the same fungicide group during the season, for any Group 2 or 9 (including combinations with Group 12), Group 17 or 7 fungicides.
3. DO NOT apply more than two consecutive sprays from the same fungicide group, for any Group 2 or 9 (including combinations with Group 12), or Group 17 fungicides, including from the end of one season to the start of the following season.
4. DO NOT apply consecutive sprays of Group 7 fungicides, including from the end of one season to the start of the following season.
5. Late season fungicide treatments should be applied before Botrytis infection reaches unacceptably high levels in the vineyard.
Downy mildew
Fungicide activity groups: Group 4 (phenylamide); Group 11 (quinone outside inhibitor); Group 40 (dimethomorph)
1. Start disease control sprays using a protectant or non-phenylamide fungicide and continue spraying at 7-21 days depending on disease pressure and rate of grapevine growth, typically when the shoots are 10 cm (E-L 12 stage) or longer.
2. When conditions favour disease development, apply two consecutive sprays of a Group 4 product. DO NOT apply more than two consecutive sprays of a Group 4 product. DO NOT apply more than four sprays of a Group 4 product per season.
3. DO NOT apply more than three consecutive sprays of a Group 40 fungicide, and no more than a total of six sprays per season.
4. DO NOT apply more than two sprays per season of Group 11 fungicides. If two consecutive applications of Group 11 fungicides are used, then they must be followed by at least the same number of applications of fungicide(s) from a different group(s), before a Group 11 fungicide is used again, either in the current or following season.
5. Apply Group 11 fungicides preventatively. 6. Apply a maximum of two consecutive applications in alternation with fungicides from a different MOA group with
satisfactory efficacy against the target pathogen/s.
Powdery mildew
Fungicide activity groups: Group 3 (DMI); Group 5 (amine); Group 7 (carboxamide); Group 11 (quinone outside inhibitor); Group 13 (quinoline), Group U8 (actin inhibitor)
1. DO NOT apply more than two consecutive sprays of a Group 3 fungicide.DO NOT apply more than three Group 3 sprays per season.DO NOT use Group 3 fungicides curatively.
2. DO NOT apply more than two consecutive sprays of a Group 5 fungicide.DO NOT apply more than three Group 5 sprays per season.
3. DO NOT apply consecutive sprays of Group 7 fungicides, including from the end of one season to the start of the following season. DO NOT apply more than four Group 7 sprays per season.
4. Apply Group 11 and other systemic fungicides preventatively.5. DO NOT apply more than two sprays per season of Group 11 fungicides.6. Where Group 11 products have been routinely used for many seasons, field research indicates there is an increased
risk of powdery mildew resistance to Group 11 fungicides occurring. To ensure continued protection against powdery mildew in these circumstances, either abstain from using Group 11s or mix Group 11 fungicides with a registered rate of a compound from an alternative chemical group for the control of powdery mildew in grapes.
7. Alternatively, if applied alone, Group 11 fungicides should be used in strict alternation with fungicides from an alternative chemical group for the control of powdery mildew.
8. DO NOT apply more than two consecutive sprays of a Group 13 fungicide.DO NOT apply more than three Group 13 sprays per season.
