Adjuvant Research That Proves Itself in the Tank

Darrin Holder
Agronomist, WinField United
Every spring, you probably make a significant investment in crop protection products. But are they performing as well as they could be? Adding a quality adjuvant to your tank mix can help more product reach its target and be more effective once it gets there.
 
Finding answers
Researchers at the WinField United Innovation Center use state-of-the-art technology to evaluate the entire crop protection product application process, resulting in the creation of leading-edge adjuvants, herbicides, insecticides and fungicides to help you be successful in the field.
 
During the growing season, we run field trials to see exactly how our adjuvants perform with a variety of crop protection products. Year-round, our staff runs many compounds through our Spray Analysis System to observe how different combinations of adjuvants and active ingredients affect spray quality. Spray chambers at the Innovation Center allow products to be tested much like they would be in the field, with the same size nozzles and nozzle orientation as a full-size sprayer.
 
Laboratory testing, as well as research conducted under regulated growing conditions in greenhouses and growth chambers, lets us test products without the unpredictability of the external environment. This leads to greater efficiency, consistency and precision. Determining product specifics such as shelf life and mixing capabilities helps WinField United bring a more complete product to market.
 
The numbers tell the story
Research indicates that WinField United adjuvants help increase the efficacy of crop protection products, giving you the opportunity to increase yield and ROI potential. Here are just a few data points.
  • MasterLock® adjuvant helps improve fungicide response on corn, increasing yields by an average of 5.7 bushels per acre.1
  • Class Act® NG® adjuvant doubles the amount of glyphosate uptake over ammonium sulfate (AMS).2
  • StrikeLock® adjuvant is as good as or better than other high-surfactant oils in weed control, outperforming them approximately 14 percent of the time.3
 
In addition, InterLock® adjuvant delivers more droplets in the ideal droplet diameter spectrum, increases droplet speed without thickening the spray and helps get more active ingredient deeper into the plant canopy.
 
The way I think about applying a crop protection product is, If I don’t do this right, I’m in a respray situation. And nobody makes money in a respray situation. You’ve got to start with the correct amount of active ingredient per acre, then use a quality adjuvant to get as much of that active ingredient as possible to the target.

Manage for More Yield on Non-Rotational Acres

Jonathan Zuk
Regional Agronomist
The advantages of crop rotation have been well documented over the years. But market conditions and on-farm needs are pushing more farmers to skip rotations and opt for continuously cropped acres instead. If you’re one of those farmers, here are some considerations to maximize productivity on non-rotated acres.
 
Continuous corn acres
Research has shown that continuous corn yield penalties were more severe in areas with low moisture and low yields.1 With that in mind, it makes sense to choose high production acres for corn-on-corn rotations, if possible. Here are some other tips to maximize yield potential.

 
  • Choose stable hybrids. Strive to find balance with a high-yielding hybrid that also carries defensive traits like strong disease and insect resistance. Trait packages that protect against above- and below-ground pests, including corn rootworm, are also a good investment for corn-on-corn acres.
  • Evaluate seed treatments. The right treatment helps protect against early-season fungal diseases and insects that might be more prevalent due to the extra plant residue and added moisture in continuous cornfields.
  • Apply foliar fungicides and insecticides. As insect and pathogen populations accumulate in soil and crop residue, the potential for damage and yield loss increases.
  • Manage residue. Extra corn residue can result in additional challenges at planting, including wetter, cooler soils. Excess residue can also have implications for nitrogen cycling.
 
Continuous soybean acres
Pests seem to be one of the biggest yield-limiting factors for soybean-on-soybean acres. Soybean cyst nematode (SCN) is historically one of the main concerns, although many farmers aren’t testing for the pest in their fields. Here are some management practices to reduce the yield penalty associated with continuous soybean cropping.
 
  • Alternate genetics. Choosing diverse seed varieties each year helps ensure common weed, insect and disease pests don’t become resistant to management strategies. WinPak® soybeans from CROPLAN® seed include a unique combination of two varieties that work together and confer different levels of protection against common diseases to help mitigate risk.
  • Treat seed. Selecting soybean varieties with the right seed treatments can provide up to 40 days of protection against early-season diseases including rhizoctonia, Pythium and sudden death syndrome.
  • Watch nutrient levels. Multiple years of soybean production can remove nutrients including phosphorus and potassium from the soil.
  • Apply foliar fungicide and insecticide. Applications at the R2/R3 growth stage can provide extra protection against late-season pests.
Strategic production practices can help you get more from non-rotational acres. Consult with your local WinField United retailer to develop a comprehensive management plan that includes the proper seed choices, crop protection products and fertilization needs for your acres.
