ARDEN HILLS, MINN. (AUGUST 18, 2025) – When growers make herbicide applications, they are looking for a clear return on their investments (ROI). While that comes primarily in the form of effective weed control, factors such as enhanced convenience and broad compatibility also can weigh heavily when determining return.
Growers now have a new tool that helps deliver all three: SuperLock™ adjuvant, a new premium adjuvant proprietary to WinField® United. This novel solution includes both drift reduction technology (DRT) and a high surfactant crop oil concentrate (HSCOC) to help ensure herbicides hit their intended targets and penetrate plant surfaces to increase yields and profitability through better weed control. SuperLock adjuvant qualifies as a drift mitigation option within the Environmental Protection Agency (EPA) Herbicide Strategy, under the Endangered Species Act.
“For growers, adding SuperLock adjuvant to their herbicide tank mixes means getting enhanced drift control, weed control and crop safety efficiently from one product,” said Joe Vaillancourt, strategic marketing manager for adjuvants with WinField United. “And it’s backed by extensive research at the WinField United Innovation Center, including more than 3,600 wind tunnel measurements and 100,000 data points in our plant phenotyping lab, so growers can be confident when adding it to their preferred tank mix.”
Vaillancourt says SuperLock adjuvant is a particularly strong fit for growers who are looking to get more from their crop oil concentrate tank mixes, mitigate crop response with specific tank mixes, and/or are already choosing to mix a DRT with a crop oil concentrate.
SuperLock adjuvant is highly compatible across a wide variety of crops and tank-mix partners, including glufosinate, 2,4-D, clethodim, glyphosate and many others, and it is approved as a required oil system for tank-mix applications of Liberty® Ultra and Enlist® One herbicides.
Retailers also will see benefits in offering SuperLock adjuvant, Vaillancourt notes.
“SuperLock adjuvant enables easier warehouse management by requiring less storage space and delivers retailers a multifunctional, differentiated solution to offer their customers,” he says. “There are so many herbicide options available, and SuperLock is the simple solution to help improve performance potential.”
