LOVELAND Products is a world leader in adjuvant know-how. Its lecithin based technology is the foundation of many of its adjuvants and it’s been able to bring to Australia a range of new lecithin based adjuvants that offer significant benefits for better pesticide application.

According to Justin Lynn, Region Fertiliser, Farm Services and Seed Manager for Landmark, Loveland has more than 40 years of adjuvant experience.

The product distributed by Nufarm in Australia - LI700, is a Loveland adjuvant. The LI in LI700 stands for Loveland Industries, a previous trading name of Loveland Products. LI700 is reputably the largest selling adjuvant globally and the unique benefits that LI700 provides are shared by the more recently introduced Loveland adjuvants Liberate and MSO® LECI-TECH®.

MSO with Leci-Tech is a methylated seed oil containing the highest quality components. Premium emulsifiers, along with Leci-Tech chemistry, deliver uniform mixing properties for excellent performance along with drift reduction, enhanced droplet adhesion and spray penetration.

“MSO with Leci-Tech is designed for use with post-emergent herbicides and has consistently demonstrated increased penetration over conventional crop oil concentrates,” Mr Lynn said.

“Liberate is an oil and surfactant product that also contains the highest quality components. Again with all the Leci-Tech chemistry benefits, Liberate is suitable for a broader range of purposes including summer spraying, knockdown and post-emergent applications.”

“Liberate is an odourless, neutral pH, 100% active adjuvant derived from soybean based materials. It contains 40% more lecithin than LI700 and gives

Coverage is one of the primary objectives with pesticide applications. The spreading and adhesion properties of Leci-Tech are ideal for maximising droplet contact area and keeping the droplets on the target. As the droplet makes contact with the target, the combination of the right sized droplets along with the adhesion properties of Leci-Tech chemistry, ensures that the droplet hits the target and stays there to provide more consistent results.

Leci-Tech chemistry a force behind Liberate and MSO

superior droplet modification properties. With Leci-Tech inside, it presents to growers an adjuvant that is ideal to use with commonly applied products such as clethodim, glyphosate, paraquat, atrazine, Velocity and many others.

“Our own trials backup the strong performance of these new adjuvants, as shown in trials at Geraldton and York with Velocity and clethodim. Along with excellent crop safety, these two adjuvants with Leci-Tech inside help; • more spray to reach the plant by

reducing spray drift; • droplets to be retained better on

the leaf by improving adhesion and spreading;

• product into the plant by increasing penetration without cuticle disruption.“Leci-Tech chemistry reduces

fine droplets without increasing the number of large droplets.

“The result is more of the right sized droplets, which not only reduces the risk of droplet drift, but also reduces shatter and bounce for optimised nozzle performance,” Mr Lynn said.

The drift reduction properties of Leci-Tech chemistry are displayed above (Leci-Tech right).

The figure below demonstrates the effect of Leci-Tech chemistry on penetration and translocation of glyphosate into and throughout the plant.

The figure below left demonstrates the effect of Leci-Tech chemistry on spray solutions by retaining more of the ‘right size’ droplets on the waxy leaf surface of common lambsquarters. Clay solution was used for a visual indicator.

The York site had some level of resistance to clethodim.Note: At this site all adjuvants provided a better level of ARG control when they were used at higher rates. Numerous Landmark trails have indicated that the level of weed control with clethodim is increased as the rate of adjuvant increases. Landmark recommends the use of 1% adjuvant rate when using clethodim.

“Using Liberate keeps things simple and gives me great flexibility as it’s the most versatile adjuvant around. I can use it pretty much all year round and not forego performance. It’s ideal for drift reduction over my RR canola which gives me peace of mind. It’s cost effective and from what I’m seeing in the field, it out performs anything I’ve used to date.”Corey Mincherton, Ballidu, WA

“In terms of drift reduction and getting product to the target, Liberate is one of the best products I have used. I have been looking for a multipurpose product like Liberate that can be used as a surfactant in summer, pre-em and post-em. Low use rates also make Liberate a cost effective option.”Nick Duane, Yandanooka, WA

A COMMON misconception is that the use of ammonium sulphate negates the effects of water hardness and that it works on all cations. This is just not the case.

Common cations found in spray water can include calcium, magnesium, iron, potassium and sodium. When certain herbicide chemistries are added to hard water the negative charges in the herbicide molecules attract the cations.

They bind together in a strong complex which can prevent or hinder the uptake of the herbicide into the plant, reducing herbicide performance.

If the spray water contains cations other than calcium, the use of ammonium sulphate to negate the binding effect is very limited.

Choice Weather Master is a water conditioning agent from Loveland Products that is effective on all types of cations. Choice Weather Master contains multiple sequestering and chelating agents that bind to ALL cations in the spray water solution to help maximise performance from herbicide applications.

Choice Weather Master should always be added to the spray tank before the addition of pesticides.
