Adjuvants have a greater impact on our spray application and performance than we appreciate. They overcome water quality concerns, leaf deposition, leaf uptake of product, and some even assist with translocation throughout the plant. However, environmental conditions have one of the most significant impacts on herbicides, insecticides, fungicides, fertilisers, biological and most adjuvants. Wash-off, degradation, and leaf surface crystallisation can severely impact the performance of foliar-applied products.
Agspec’s unique range of pine-resin polymer adjuvants, Hygro-Stic®, Flextend® and Flexstic®, not only assist with leaf deposition, coverage, and uptake, but they also play an important role in minimising the negative environmental impact on our foliar spray program.
With protectant fungicides, e.g. copper and mancozeb, these adjuvants help with coverage, re-distribution, and, importantly, retaining more product on the leaf surface even following overhead irrigation or rainfall events. Commonly used wetting agents are renowned for increasing wash-off from the leaf. Hence, Hygro-Stic, Flextend and Flexstic are preferred adjuvants when applying protectant fungicides.
Hot, dry conditions (high delta-T) cause spray droplets to evaporate before reaching the leaf, or the spray droplet dries so rapidly that it limits the leaf uptake of the product. Hygro-Stic, Flextend and Flexstic all extend droplet lifetime, allowing greater uptake of products similar to glufosinate and translocation of systemic products like glyphosate, systemic fungicides, and foliar nutrients.
With the heat comes high UV conditions. Nearly all biologicals are highly sensitive to rapid UV breakdown. Hygro-Stic, Flextend and Flexstic adjuvants have the ability to filter UV light, protecting biologicals from breakdown.
Phil Lintern, our seasoned Adjuvant Manager with over 40 years of expertise, affirms, “Hygro-Stic, Flextend, and Flexstic stand out being excellent in the wet and but even better in the dry spraying scenarios”.
