1. WEATHERWATCH.The following weather information summarizes data collected at various Ohio Agricultural Research Development Center (OARDC)Weather Stations spanning the dates from May 1-18, 2010, with the exception of the soil temperatures which are readings from Tuesday,May 18, 2010 at 6:00 p.m.

Joe Rimelspach kicked of his weekly report by saying, "it has been pretty nice weather if you are an infectious disease." A common wordexpressed by BYGLers across the state on this week's conference call was "rain." Wet weather has been experienced by many and soilsare soggy.

2. PLANTS OF THE WEEK.*ANNUAL - SWEET ALYSSUM (Lobularia maritima). Sweet alyssum is a wonderfully fragrant annualused as a border plant or in containers and hanging baskets. Tiny clusters of flowers cover the entireplant during most of the growing season. However, during the heat of the summer, flower productionslows only to resume again with cooler temperatures. When flower production slows and plants appearleggy, shearing or a good "hair cut" helps to rejuvenate the plant and keep it looking great the rest ofthe season.

The plants grow around 6-8" tall and in a mound around 1' wide. Several cultivars are available andflower colors are white, purples, and pinks. A recent Proven Winner introduction, 'Snow Princess' is abreakthrough in Lobularia breeding for heat tolerance and season-long performance. In OSUE field

trials in Clark County, 'Snow Princess' bloomed and was outstanding the entire summer, garnering it high ratings in the trials.

*PERENNIAL - BLUE STAR (Amsonia hubrichtii). This underused, US native packs a 2-season punch, offering powdery blue flowersin spring and then wonderful golden-yellow fall color! Blue star (sometimes called Arkansas amsonia, Arkansas blue star or Hubricht'samsonia) has delicate, feathery, light green foliage topped with pale blue star-shaped flowers in April-May.

The plant is easily grown in average, medium, well-drained soil in full sun to part shade. The shape is a rounded-mound that growsaround 2-3' tall and as wide. Consider cutting back the stems by about 6" after flowering to help keep stems upright and to shape plantsinto a nice foliage mound. There are no serious insect or disease problems.

Blue star is an excellent choice in borders, rock gardens, cottage gardens, native plant gardens, or massed in groups for a greater effect.

*WOODY - DOUBLEFILE VIBURNUM (Viburnum plicatum f. tomentosum). Doublefile viburnum arebeautiful large deciduous shrubs that provide multi-season interest for the landscape. Flowers appear inspring and are white. The doublefile viburnum flowers are on a 4-6" diameter flat-topped cyme. Theinner circle of fertile flowers are not showy, while the outer ring of sterile flowers are very attractive.June through August, beautiful deep red stalks develop small red fruits that birds love to eat. In the fall,the doublefile stalk turns either a light red or deep maroon and leaves turn dark green. Besidesoccasional stem dieback, found to be more prevalent in wet areas, they have no significant disease orinsect problems. The plant should be located in part shade, but will tolerate full sun if providedadequate water in July and August. Avoid locations with poorly drained or heavy soils. Several cultivars

to check out are, 'Lanarth,' 'Mariesii,' and 'Shasta.'

Illinois Home Landscape Shrub Selector

*VEGETABLE - EDAMAME OR EDIBLE SOYBEAN (Glycine max). Edamame is a relatively new crop to gardeners in the UnitedStates. However, it's an ancient Asian vegetable growing in popularity. These specialty varieties of soybeans are harvested in the greenstage and have high nutritional value and health benefits. There are 100 calories, 4 grams of fat and 10 grams of protein in a 1 cupserving.

Edamame are very easy to grow and are similar to field soybeans in their needs. They take up to 90 days to mature so plant now. Plantthem in rows 2-3" apart and the rows 15-30" apart. Protect them from rabbit and deer if these critters are a problem. Pick when pods fillout but are still green.

The edible varieties are different from field soybeans as they are more suitable for fresh eating. They are generally larger-seeded,sweeter, and easier to digest than field soybeans. There are several cultivars available including 'Green Pearls' (early variety, 65 days),'Butterbeans' (90 days with a sweet buttery taste), and 'Black Jet' (104 days to maturity with jet-black soybeans).

*THE WEEKLY WEED - QUACKGRASS (Elytrigia repens). This week's weed is an invasive perennial, establishing itself in densemats, and reproducing by seed and underground rhizomes. The name 'quack' is a variation of the German 'quecke', which means 'tolive', referring to the persistent nature of this weed. Quackgrass (also known as: Agropyron repens, Elymus repens, Triticum repens,couch grass, devils-grass, knot-grass, quick grass, quitch grass, scutch-grass, twitch, and wheat grass) is one of the most troublesomeperennial grassy weeds. Quackgrass is a creeping, perennial grass, with auricles that clasp the stem, rhizomes, and a long, narrow spiketopped with a wheat-like seedhead. It is typically found in crop fields, roadsides, river banks, turfgrass, lawns, nurseries, andlandscapes. Growing in a variety of soil types, it also has a high tolerance for drought and salinity, reaching an unmowed height 3 1/2'.

Quackgrass can quickly dominate a lawn.

To control quackgrass chemically, a non-selective herbicide is required, when the lawn is growing actively appling according to the

manufacturer's instructions. The application will kill the lawn grass and all monocots (daylilies, iris, gladiolus, lilies) once it contacts theleaves as well as the quackgrass. It may take more than one application to completely eradicate quackgrass. Control of quackgrass shallmean preventing production of viable seed and destroying the plant's ability to reproduce by vegetative means. Rhizomes may be handdug as much as possible without breaking them off in the soil, then dried and disposed of. Any newly germinated plants can be easilyhoed out and they will dry up and die rapidly on a sunny day. Quackgrass is a tough weed to eliminate, but by using the proper methodsit can be eradicated successfully.

3. HORT SHORTS.A. GROWING DEGREE DAYS (GDD).

GDD is a measure of the daily maximum and minimum temperature and directly relates to growth anddevelopment of plants and insects. The GDD of any zip code location in Ohio is estimated using theGDD of ten OARDC weather stations and available on the web at: [ http://www.oardc.ohio-state.edu/gdd/ ].

The range of GDD accumulations in Ohio from north to south is 359 to 658. Following is a report ofGDD for several locations around Ohio as of May 19, 2010: Painesville, 359; Cleveland, 405; Toledo,487; Canfield, 425; Findlay, 499; Wooster, 460; Coshocton, 532; Columbus, 596; Springfield, 565;Dayton, 571; Cincinnati, 606; Ironton, 627; Portsmouth, 631; and Piketon, 658.

To put these GDD accumulations into perspective, the following is an abbreviated listing of plant and insect species with their respectivephenological event and average GDD accumulations at which these events occur. Due to variations in weather, temperature, humidity,etc., these events may occur a few days earlier or later than predicted by the average GDD. By looking at a city, town, or village nearbyon the above list, or visiting the above website, one can see what is taking place in the landscape.

B. TO PLANT OR NOT TO PLANT? THAT IS THE DILEMMA! All good horticulturists know that one doesn't plant in wet clay soil, right?However, spring means the job has to be done, and sometimes planting in wet soils is unavoidable. If at all possible, try to avoid plantingin wet clay soils as this leads to compacted soil and clod formation that is very difficult to repair. Working in wet soils compacts airspaces leading to problems for plant root growth.

The basic way to check for soil wetness is to grab a handful of soil and press; if the soil crumbles, it's good to go. If the soil stickstogether and stays molded, it's too wet. Another way to tell is if the soil sticks to your boots or the shovel, it's too wet! BYGLersrecommend waiting if at all possible for the soil to dry out. However, BYGLers also know that Mother Nature doesn't always play fair and

"you gotta do what you gotta do!"

C. WILT PREVENTION OF CUCURBITS REVISITED. Jim Jasinski (OUS Extension Vegetable IPM Specialist) wrote to comment on thearticle on wilt prevention in cucurbits. Jim wrote, "True, conventional insecticides can help reduce the beetles (sic STRIPED CUCUMBERBEETLES (Acalymma vittatum)) and therefore the wilt, but there are other cultural options as well ranging from row covers, delayedplanting, transplanting, trap crops, and the use of Surround (kaolin clay) as a feeding deterrent instead of relying on the hard stuff."BYGL thanks Jim for providing the additional alternative management suggestions. For more information on this topic, see OSUExtension FactSheet HYG-2205-09, "Integrated Pest Management for the Home Vegetable Garden" which can be found on OhioLine athttp://ohioline.osu.edu/hyg-fact/2000/pdf/2205.pdf .

Striped Cucumber Beetle

D. FRUIT THINNING CAN HELP IMPROVE FRUIT QUALITY. At times most fruit trees may set too many fruits which can reduce fruitsize, color, and quality due to competition for resources between the developing fruits. Too heavy of a fruit load can also reduce coldhardiness of fruit trees by reducing the amount of reserves sent to the roots before the onset of winter. Large tree limbs can also bebroken off by the weight of an excessive fruit load. Peaches and certain cultivars of plums usually set too many fruits when they are notthinned by a spring frost. Excess fruits should be removed by hand when young developing fruits are about 3/4" in size, around June 1-15, leaving 4-6" between peaches and 2-3" between plums. Apples do not usually set heavy crops every year.

Some apple cultivars will not bear fruit the year following a year of an excessive crop. This phenomenon is called "alternate yearbearing." When a heavy set does occur, the fruits should be thinned to 6" apart during early June. Use the thumb and forefinger to snapthe apples from the stem, leaving the stem on the tree. When there is more than one apple in a cluster, remove the smaller fruits andkeep the largest apple, which is called the "king apple." If this is done no later than 50 days from when the trees are in full bloom, treesare more likely to produce a good crop the following year. Refer to OSU Extension Bulletin 940, "Midwest Home Fruit Production Guide"for additional information.

Midwest Home Fruit Production Guide

E. WHAT IS IN COMMERCIAL FERTILIZER? Nitrogen (N) is the plant nutrient most often in short supply in the soil. It is usuallynecessary to supply this element each season. Phosphorus (P) and potassium (K) are also required in large amounts. Nitrogen isessential for vigorous vegetative growth and development. Phosphorus is necessary for good root development, and for fruit and seedproduction. The role of potassium is not as well understood, but is important for overall plant development. For this reason, these are thethree nutrients that are almost always found in commercial fertilizers. Commercial fertilizers, whether organic or inorganic, always havethree numbers printed on the bag or container. These numbers represent an analysis of the percentage of nitrogen (N), phosphorus(P2O5) and potassium (K2O) in the product. For example a fertilizer with an 8-16-16 analysis contains 8% N, 16% P and 16% K. Therest of the product is usually an inert carrier material unless otherwise stated on the label. A complete fertilizer will have a number for allthree nutrients.

Some fertilizers are incomplete, that is, they contain only one or two of the nutrients. Urea, for example, has an analysis of 45-0-0, and

contains 45% N with no P or K. Inorganic or chemical fertilizers usually have a higher analysis than most organic fertilizers and are lessexpensive. The nutrients in chemical fertilizers are in a form that is readily available to plants. Organic fertilizers contain nutrients informs that must be chemically changed in the soil before the plants can use them. These nutrients, although not immediately available,are usable to the plants over a longer period of time. Some chemical fertilizers will contain nutrients in both readily available and slow-release forms. Organic fertilizers are less likely to burn plants and often contain several micronutrients in addition to N, P and K. Someinorganic fertilizers also contain micronutrients.

F. DEADLEAFING TULIPS AND DAFFODILS.

Many gardeners have heard of deadheading, which is the removal of spent flowers. What about"deadleafing"? Deadleafing is the removal of yellow, brown, or dead leaves. The leaves of tulips areturning yellow and brown in central Ohio this week. The yellow leaves are going to die soon and can beremoved by hand pulling. Deadleafing can be performed on other plants too. The dying and deadleaves can be a source of damaging insects and diseases. Removal of yellow leaves from tulips shouldhelp tidy up the gardens as well. Do not cut or braid foliage, but allow it to die down naturally. Foliagecan be removed when it has yellowed, fallen over, and comes loose when slightly tugged.

Of all the bulbs, tulips are "heavy feeders" and require fertilization as foliage emerges and again afterflowering. Fertilize other bulbs after flowering to support foliage and increase bulb size. Use a complete fertilizer, such as 12-12-12, atrate of 1 lb per 100 sq. ft.

4. GREEN SHORTS.A. LOOK UP IN THAT ASH TREE - WHAT DO YOU SEE? Sunday, May 23, 2010 is the official kick-off of Emerald Ash Borer (EAB)Awareness Week. This week has been designed to raise awareness about the exotic invader already responsible for killing millions ofash trees, and to urge individuals not to spread this deadly pest faster and further through artificial movement (i.e., firewood, ash trees,or ash logs). The timing of the week leads to the unofficially start of the camping season, just prior to the Memorial Day weekend and awebsite called "Stop the Beetle" has been designed to encourage people to buy firewood near the location where it will be burned. Checkout the website at http://stopthebeetle.info/ and make a promise, and encourage others, not to spread EAB.

While BYGLers have observed the beginning of adult emergence in recent weeks, this is a shout out to readers to see what is beingseen across the Buckeye State. While adult emergence coincides with the blooming of black locust, beetles will continue to emergethroughout the summer, likely peaking later next month. Adult beetles are normally present through most of the summer, with activitywinding down usually in August.

Let us know what you are seeing when you look up into the canopies of ash trees in your area. If you see EAB or evidence such as D-shaped exit holes, BYGLers want to know. Send an e-mail to Amy Stone at stone.91@cfaes.osu.edu and describe what you are seeingand the actual location. Specimens can also be submitted for confirmation to the Ohio Department of Agriculture (ODA) along with theirSpecimen of Determination Form. This form is on their website and can be downloaded at:http://www.agri.ohio.gov/public_docs/forms/Plant/EAB/Plnt_4207-001.pdf . By submitting samples, county and state infestation maps canbe updated and give a clearer picture of where EAB infestations area.

B. MASTER GARDENER (MG) VOLUNTEERS CELEBRATE MGV WEEK IN OHIO.

Anyone who works with or knows an MG volunteer is encouraged to give them a big pat on the back and a thank-you this week.Governor Strickland proclaimed the 3rd week in May to be Ohio MGV week in order to recognize the volunteers and their service as wellas to promote the program. Ohio has more than 3,500 volunteers who gave over 151,000 hours of service to their communities in 2009.

C. GOVERNMENT "GREEN" MANADATES ARE POTENTIAL LANDSCAPE INDUSTRY OPPORTUNITIES AND CHALLENGES.Virtually all levels of government now have substantial "green" mandates. Most of those are now based on the US Green BuildingCouncil (USGBC) Leadership in Energy and Environmental Design Program (LEED). For example, on September 27, 2007, the OhioSchool Facilities Commission (OSFC) passed Resolution #07-124, approving the incorporation of energy efficiency and sustainabledesign features into all future and some previously approved school projects. All K-12 public school projects approved by the OSFC arerequired to meet a minimum of LEED for Schools Silver certification, with strong encouragement to achieve the Gold level. There isadditional emphasis on maximizing Energy & Atmosphere credits. The resolution directs OSFC to cover all LEED registration andcertification fees and to provide a supplemental allowance to project budgets for the incorporation of sustainable, green strategies.

While most of the LEED program is currently directed towards facilities, some pertain to the landscape. That could present bothsignificant sales opportunities and challenges for the landscape industry. LEED points are awarded for permanent erosion controls suchas terracing, retaining walls and planting trees, shrubs, and groundcover and the management of runoff from roofs through systems suchas swales, rain gardens, rainwater cisterns, and vegetated roofs. On the other hand there are significant limitations on the use of turf. Forexample, any turf must be drought tolerant and cannot be used in densely shaded areas or on slopes greater than 25 degrees. If morethan 60% of the designed landscape softscape area is conventional turf, no points are given (up to 3 points are given if 20% or less ofthe softscape area is conventional turf). Note that conventional turf is defined as any turf that requires regular mowing, watering, and/orchemicals. Native grass mixes that do not require regular maintenance are not considered conventional turf.

Look for the continued discussion of this topic in next week's BYGL. For more information on USGBC LEED Public Policies, visit thefollowing website: http://www.usgbc.org/DisplayPage.aspx?CMSPageID=1852 .

5. CLINIC CLIPS.This past week at the Clinic, clinicians have seen boxwoods with Volutella leaf and stem blight and boxwood psyllid damage. Astrawberry plant was diagnosed with angular leaf spot (bacterial blight), which is a bacterial disease of strawberry leaves. Angular leafspot (Xanthomonas fragariae) usually appears during periods of rain in the spring and can overwinter on the previous year's leaf debris.The bacteria spread through water splash and can become systemic in the plant. If an infection becomes established a grower shouldremove infected plants and replant with less susceptible varieties. Hot, dry weather and healthy vigorous plants are the bestmanagement tools for this disease.

On the insect side of the Clinic, a European hornet was found on top of the frames of a bee hive, under the inner cover. The hornet waslarger than several pinned specimens in a reference collection and very dark. It may have been stung to death by the honey bees andhad already begun to rot. Although not often encountered in central Ohio this early in the season, European hornets are known to attackhoney bee hives and eat the workers. The beekeeper stated that he has seen them flying around the last few weeks on warm sunnydays.

Raspberry canes submitted to Celeste Welty from a grower south of Columbus had been tunneled by small carpenter bees (Ceratinasp.). Damage from these small solitary bees is sometimes encountered by raspberry growers however their pollinating service usually

compensates for the loss of some raspberry canes. Sadly, the grower of this sample reported that 20% of the canes were showing thesymptoms (wilting and dying back of canes). The female tunnels the entire pith of the stem (1-8" deep) then makes individual chambersprovisioned with pollen and nectar for each developing larva. The first adults to eclose from pupation are at the base of the stem. Instead of chewing a way out horizontally, these new adults crawl upward through the stem, carefully moving the "floors" of eachchamber, and shifting the pupa, then replacing the pupa and chamber floor as it crawls up to the next floor. The small, iridescent blue orgreen bees of this genus are very different from the other member of the subfamily Xylocopinae, the large carpenter bee, known to chewperfectly round holes of exposed wood.

6. BUGBYTES.A. OYSTERSHELL SCALE.

Curtis Young reported observing a heavy infestation of oystershell scale (Lepidosaphes ulmi) causingbranch dieback on a maple in western Ohio. This armored scale has been reported on over 130 hostplants including a wide range of trees and shrubs. It is particularly common on ashes, cotoneaster,dogwoods, lilacs, maples, poplars, roses, and willows. Dave Shetlar noted that although this scale hasonly one generation per year in Ohio, infestations can rapidly build within 1-2 years to levels that causesignificant plant injury including branch dieback and even plant death.

As with all armored scales, oystershell scale feeds by inserting their piercing-sucking mouthparts intoplant stems to withdraw nutrients from non-vascular stem cells. Since they do not extract juices from

vascular tissue, oystershell scales do not exude the sugary, sticky "honeydew" that is associated with "soft" scales. The scale has onlyone generation per year in Ohio.

Mature females are the most obvious stage of this scale and they are found on the bark of their host plant. The females are around 1/16"long and like all armored scales they are protected by a hard waxy covering. The shiny covering is noticeably convex in shape and darkgray to brown in color. The scale has been described as resembling miniature clam shells or oyster shells; thus the common name. Theirsize, color, and slight banding cause the mature females to blend-in with the bark making low populations difficult to detect. However,dead females scales may remain attached to their hosts for several years before peeling off.

The scale spends the winter as eggs beneath the bodies of dead females. Eggs hatch over a period of about two weeks in mid-to-latespring. The resulting mobile first instar nymphs (crawlers) are pale yellow and smaller than a pin head. However, they may be detectedusing double-sided sticky tape attached to the bark. Standard control recommendations focused on using contact insecticides includingsoaps and oils to target the crawler stage. However, if the infestation is heavy, the bodies of dead females may protect some crawlersfrom contact with the insecticide. Dave recommended making an application of the systemic insecticide dinotefuran (e.g. Safari). Thishighly soluble insecticide moves rapidly into plants and has been particularly effective against armored scales as well as soft scales.

B. DECIDUOUS TREE SAWFLIES.

Dave Shetlar reported observing BLACKHEADED ASH SAWFLY (Tethida barda) on its namesake hostand SPINY OAK SAWFLY (Periclista albicollis) on white oak in central Ohio. Joe Boggs noted that hefound SPINY ASH SAWFLY (Eupareophora parca) on green ash in the southwest part of the state. Theleaf-feeding damage caused by these sawfly larvae may mimic leaf symptoms caused by variouslepidopteron caterpillars. Thus, it is very important for developing effective management strategies toproperly identifying these sawflies.

The larvae of these three sawflies share several characteristics. They have black head capsules("heads") and are light green to yellowish-green although their semi-transparent bodies allow their

digestive tracts to be clearly visible. Blackheaded sawfly larvae are free of spines whereas the larvae of the spiny ash and spiny oaksawflies are covered in short, bifurcated (twin-pointed) spines. The spines on spiny ash sawfly larvae are white while the spines on spinyoak sawfly larvae are black and arise from black spots on the body. Once the sawfly larvae complete their development, they drop to theground to pupate and spend the winter in the soil. The sawflies have one generation per year.

The larvae of the three sawflies feed gregariously side-by-side in groups of 4-20. Eggs hatch whileleaves are still expanding and early instar larvae feed by producing small holes in leaflets. Later instars

consume entire leaves. The leaf damage may mimic the leaf symptoms created by the caterpillars ofseveral lepidopteron defoliators including SPRING CANKERWORM (Paleacrita vernata), FALLCANKERWORM (Alsophilia pometeria), FOREST TENT CATERPILLARS (Malacosoma disstria), orGYPSY MOTH (Lymantria dispar). The naturally occurring bacterium, Bacillus thuringiensis (Bt), is veryeffective against the lepidopteron caterpillars if applied to early instar stages, but Bt will not kill sawflylarvae. Conversely, the systemic insecticide imidacloprid (e.g. Merit) is effective against sawflies but noteffective against lepidopteron caterpillars.

C. WOOLLY BOOLLY BEECH LEAVES.

Joe Boggs reported that the leaves on some European beech (Fagus sylvatica) trees in southwest Ohioare becoming festooned with the white, waxy, flocculent material exuded by the nymphs of the woollyaphid, Phyllaphis fagi. The aphid has no approved common name, but entomologists generally refer toit as the WOOLLY BEECH LEAF APHID. The aphid is a European native that retains its preference forEuropean beech in the U.S.

The woolly aphid appears to avoid American beech (F. grandifolia); however, it is sometimes mistakenfor the similar looking BEECH BLIGHT APHID (Grylloprociphilus imbricator) that prefers Americanbeech. Nymphs of the blight aphid also exude white, waxy filaments, and the aphid forms large colonies

that first appear on twigs and branches, then on leaves. The blight aphids wiggle their abdomens in unison when disturbed, giving rise tothe unapproved common name "boogie-woogie aphid." Woolly beech leaf aphid colonies appear on leaves and occasionally creep ontosurrounding twigs. The nymphs also wiggle when disturbed, but their "dance" is very subdued and less organized.

Reports from Europe indicate the woolly beech leaf aphid can cause significant injury to its beech host;however, such reports are rare in the U.S. The primary impact on European beech in the U.S. is thereduced aesthetics caused by the high contrast between the brilliant white aphid colonies and thelustrous dark green or dark purple beech leaves. The aphids also exude copious quantities ofhoneydew and droplets of this sugary, sticky substance creates a gummy mess on underlying beechleaves, sidewalks, building decking, slow-moving gardeners, etc. The deposited honeydew maybecome colonized with black sooty molds adding to the unsightly appearance of the goo. Honeydewdeposits can be washed away with a coarse stream of water, and most insecticides labeled for use onEuropean beech will reduce aphid populations if control is considered necessary.

D. EUROPEAN HORNETS.

Barb Bloetscher reported that she received a dead European hornet (Vespa crabro) collected by abeekeeper from inside a beehive in central Ohio. Apparently, the hornet had been stung to death whileattempting to grab bee larvae from the hive. European hornets were first found in the United States inNew York State around 1840. Since that time, the hornets have spread to most states east of theMississippi and a few states to the west. European hornets are impressively large, measuring 1-1 1/4"in length. Their black and yellow markings on their abdomen make them look like yellowjackets onsteroids; however, their head and thorax have distinct chestnut colored markings. Yellowjackets haveblack and yellow markings on the head and thorax.

Technically, this non-native is the only true hornet found in Ohio. Taxonomically, our native bald-faced hornets are grouped withyellowjackets. Finding the European hornet in a beehive is not unusual since our native yellowjackets and wasps will occasionally

attempt ill conceived forays into beehives to grab honeybee larvae; however, the hornet was a worker. This is unusual since our nativeyellowjackets and wasps are all primarily queens at this time of the year; they have just started to build their annual nests.

Finding a European hornet worker at this time of the year demonstrated one of two unusual traits that are not shared with our nativewasps and yellowjackets. European hornets construct paper nests similar to bald-faced hornets; however, they prefer to nest in hollowtrees and will occasionally nest in the walls of homes. Dave Shetlar noted that the European hornet nests will occasionally survive thewinter if they are sufficiently protected. Indeed, Dave once observed a nest that had made it through three winters in Ohio. Our nativeyellowjackets and wasps spend the winter as queens located away from their nests in protected locations. They build new nests in thespring; old nests are not re-used.

The second unusual trait of European hornets involves their feeding behaviors. Like our native yellowjackets and wasps, they will killcaterpillars and sawfly larvae and grind them up with their powerful mandibles to feed their young. However, unlike our natives,European hornets will also use their mandibles to cause significant girdling damage to twigs and branches of trees and shrubs bystripping bark to the white wood. It is speculated they extract sugar from the consumed phloem tissue. The non-native hornets havebeen observed causing damage to a wide range of trees and shrubs including ash, birch, boxwood, horse chestnut, lilac, rhododendron,and viburnum.

E. A FIERY PREDATOR.

Localized populations of several general defoliating caterpillars have been high this season in southernand central Ohio. Inevitably, meat-eaters in the form of predaceous insects such as the FIERYSEARCHER CATERPILLAR HUNTER (Calosoma scrutator) are attracted to the herds of free rangingcaterpillar meat. Unfortunately, it is common for the predators to appear in unexpected places in searchof food once the caterpillars vacate the scene by completing their development. Joe Boggs noted thathe has received phone calls from homeowners and businesses reporting breaking and entering byhungry fiery searcher caterpillar hunters.

The fiery searcher is in the beetle family Carabidae, or "Ground Beetles." Measuring over 1 1/4" inlength, it is one of the largest ground beetles found in Ohio. The front end of the beetle, the business end, sports sickle-shapedmandibles used to reduce hapless caterpillars into beetle fodder. The beetle has long, purplish-black legs and antennae. The abdomen isalmost rectangular, with the posterior end slightly pointed. The hardened front wings (elytra) covering the abdomen are metallic greenwith fine longitudinal grooves. The outer edges of the elytra are reddish-orange; a striking feature that is responsible for the fiery commonname.

The fiery searcher lays eggs in the soil and the resulting elongated larvae also sport impressive mandibles that are likewise used togrind-down the bodies of their insect prey. The life cycle of the searcher is usually completed within one year; however, adults may livefor 2 to 3 years, spending the winter beneath bark or in the soil.

The searchers hunt at night and hide during the day; however, they are strongly attracted to lights which may draw them towards andinto homes. Given the extremely beneficial nature of the fiery searcher, such wayward intruders should be gently coaxed outdoors ...very gently, since they can bite and emit a foul odor when mishandled!

Clemson University Entomology Museum Note

F. WINDSHIELD WIPES.

BYGLers also ran into a few other insects this week including:

*Dave Shetlar reported that FOREST TENT CATERPILLARS (Malacosoma disstria) have largelycompleted their development on the OSU Columbus campus and are being supplanted by GYPSYMOTH (Lymantria dispar) caterpillars. Most of the gypsy moth caterpillars are in the 4th instar stage witha few reaching the early 5th instar stage. Dave noted that defoliation caused by both species issporadic with the gypsy moth caterpillars causing less damage.

*Dave also noted that the distinctive "windowpane effect" caused by the feeding activity of variousmembers of the "roseslug sawfly complex" is becoming very evident on rose leaves in central Ohio. Thepossible culprits include the BRISTLY ROSESLUG SAWFLY (Cladius difformis), the ROSESLUG(Endelomyia aethiops), and the CURLED ROSE SAWFLY (Allantus cinctus). Early instar larvae ofthese sawflies feed as leaf skeletonizers on the lower or upper leaf surfaces, depending upon thespecies. The corresponding epidermis on the opposite side of leaf remains intact and eventually turnswhite producing the "windowpane" symptom. Later instars feed between the main veins producing "see-through" leaves. Bristly roseslug is a "season-long" pest with as many as six generations occurring inOhio. The curled rose sawfly has two generations per season, and the roseslug only one generation.

7. DISEASE DIGEST.A. MUSHROOM MANIA.

A few of the participants in the BYGL conference call noted the profusion of mushroom developmentaccompanying the cool, wet weather this past week in Ohio. At a recent meeting with many of theBYGL writers in Columbus, Ohio, all noted the fabulous display of mushrooms or "fruiting bodies" of theAgrocybe species of fungi. These spore dispersing structures appeared by the thousands, literallymasking the mulch in a landscaped bed of daylilies. Most of our landscape evident mushrooms aresaprophytic in nature. Saprophytes are an organism that feeds on dead organic material, usually bydecomposing and absorbing it, thereby assisting in its decay. More than likely the fungus had colonizedthe mulch, its bounty of detritus, and then produced the fruiting bodies (mushrooms) to further populatethe exquisite meal of mulch.

Many species of mushrooms grow or expand rapidly, to seemingly appear out of nowhere overnight and astound all who notice theaddition to the landscape. These fruiting bodies can pop up anywhere in the landscape, including in middle of the lawn growing from aburied dead tree root hidden underneath the turf. All that is required is a stash of dead organic matter. In reality, most species ofmushrooms take several days to form and develop the mushroom-like fruiting body, although they are able to expand rapidly byabsorbing fluids. This is why the cool, moist weather seems to bring out the best—in mushroom formation!

8. TURF TIPS.A. 2010 FUNGICIDE RECOMMENDATIONS FOR TURFGRASS. Fungicide recommendations for 2010 for turfgrass are now available.This year's revisions on turfgrass fungicide recommendations can be found on the OSU Turf Disease website at: http://turfdisease.osu.edu . Look under the publications section for the latest version of "Management of Turfgrass Diseases." Be advisedthat the OSU Extension Bulletin L-187, "Management of Turfgrass Pests: Weeds, Diseases, and Insects 2004" available on Ohioline isan old version and some recommendations are not complete.

B. LAWN AND HIGH CUT TURFGRASS DISEAES. Joe Rimelspach reported that several turfgrass diseases have been highly favoredby the recent weather conditions that Ohio has experienced over the past couple of weeks. Those turfgrass diseases include thefollowing:

*RED THREAD. This relatively superficial disease has become active in many parts of the state, especially on ryegrass and fine fescue.Red thread can be found on all cool season grasses depending on the situation. However, it is most common on perennial rye, finefescue, and to some degree on Kentucky bluegrass. The disease can be identified form the pinkish to reddish colored patches. The colorand texture can vary considerably. Often, the patches will appear to give a pink color to the leaf blades or to resemble pinkish globs ofbubble gum or cotton candy on the leaf blades.

This disease is strictly a superficial problem and one that will not kill the turf. Under serious conditions, it can reduce the overallappearance of a lawn. Make sure the lawn has adequate nitrogen and phosphorus to manage a healthy robust stand of turf. A deficiencyof either significantly increases disease severity. Fungicide programs can be considered in unusual situations where the disease needsto be prevented.

*LEAF SPOT - MELTING OUT. Several weeks ago, leaf spot was reported to be active. On lawns that are susceptible to the disease,there may be extensive thinning of the turf. This problem is primarily on common Kentucky bluegrass lawn areas and can be quitedecimating to the turf. The leaf spotting stage will continue with cool, wet weather conditions. With the advancement of warmer and dryerconditions, the disease progresses down the stem tissue and into the crown which can cause the turf to thin.

To manage the disease, properly mow the turf high to allow long leaf tissue for maximum photosynthesis and food production for theplant and to prevent stressing the turf from scalping. A sound fertility program is also beneficial to maintain the plants during this diseaseperiod but avoid high rates of nitrogen which will increase severity. Application of a fungicide would not produce quick results since thedisease has become firmly entrenched in the turf plants. Fungicides may help in recovery; however, progress will be slow. Often theexpense of the program is not warranted.

*PATCH DISEASE ALERT. If you are managing lawns that have had a history of necrotic ring spot or summer patch now is the time toconsider the first application of a preventative fungicide program. There are various rules of thumb. However, once the soil temperaturesreach approximately 60F or slightly warmer at a 3" depth for several days in a row, research indicates that this is an ideal time to applythe first fungicide application. These materials must be applied with high volumes of water so that they will be drenched into the crownand upper root system to be the most effective. Since the disease is a crown and root disorder, the fungicides must reach this part of theplant to be highly effective. If there are questions about this, refer to our summer patch fact sheet for more information.

Look under publications at http://turfdisease.osu.edu for the "Management of Turfgrass Diseases Bulletin" for the latest fungiciderecommendations for 2010.

C. GOLF COURSE DISEASE UPDATE. The follow diseases and disorders are active and have been reported or identified on samplesto the C. W. Ellett Plant and Pest Diagnostic Clinic:

DOLLAR SPOT on fairways and tees.RED THREAD mainly on perennial ryegrass and fine fescue may be seen on bentgrass.MICRODOCHIUM PATCH (Pink snow mold) this week has been PERFECT weather conditions for this disease. At this time ofyear the disease is primarily on annual bluegrass (Poa annua). The spores are easily move in water, symptoms may follow waterrunoff patterns, and tracked by mowers.LEAF SPOT on creeping bentgrass greens has occurred at 3 different golf courses. The annual bluegrass is usually normal andonly the bentgrass affected which seems to slowly thin and turn a dark brown rust color.FOLIAR/LEAF DAMAGE on greens from mower damage and/or aggressive sand top dressing and dragging into the canopy.Check the quality of cut and leaf conditions by carefully examining the greens with a hand lens.

9. INDUSTRY INSIGHTS.A. FIRST DETECTOR TRAINING FOR OHIO, EDUCATE TO DETECT. Have you ever looked at a plant in the landscape and thought"That doesn't look normal" or "I've never noticed that insect before"? If you have then you may want to consider becoming a FirstDetector for Ohio. The First Detector program is part of the National Plant Diagnostic Network (NPDN), a national program connectingLand Grant Universities and state and federal regulatory agencies such as Ohio Department of Agriculture (ODA) and the United StatesDepartment of Agriculture (USDA). As a First Detector, one will help promote awareness and early detection of possible exotic pests andbe a key component of NPDN. Anyone can be a First Detector from homeowners and Master Gardeners to Certified Crop Advisors andCounty Educators.

To become a first detector, one needs to complete a series of on-line training modules or sessions. The training modules can be done atone's own pace online by going to http://cbc.at.ufl.edu/ , creating a user account, selecting the "Go to the NPDN On-Line CropBiosecurity Course," and working through each module. One can request a certificate upon completion of the 6 on-line modules. Onceone becomes a First Detector, they can choose to receive the monthly First Detector newsletter.

If web-based training doesn't suit you, training sessions are offered by the C. Wayne Ellett Plant and Pest Diagnostic Clinic inconjunction with other Ohio State University educational events. Check the clinic's website http://ppdc.osu.edu, under the First Detectortab, for up-to-date training session opportunities and links.

10. COMING ATTRACTIONS.A. EMERALD ASH BORER (EAB) AWARENESS WEEK. Ohio will once again be participating in this year's EAB Awareness Week,along with 15 other states. This year's dates are May 23-29, 2010. The purpose of the weeklong observation is to increase theawareness about this invasive pest and the importance of not artificially spreading this pest further and faster.

The United States Department of Agriculture (USDA) Animal Plant Health Inspection Service (APHIS) has created a "Burn It Where YouBuy It" campaign to get the word out about importance of not moving firewood. Information can be found on [ http://stopthebeetle.info ]
