This new active ingredient will help farmers control weeds
The Environmental Protection Agency (EPA) is proposing registrations for two products containing a new active ingredient called diflufenican.
Diflufenican, a Group 12 selective contact and residual herbicide from Bayer Crop Science, would help corn and soybean growers control weeds like waterhemp, Palmer amaranth, and other pigweed species.
“This new active ingredient would give farmers an additional tool to help manage crops and increase yields in order to provide a healthy and affordable food supply for our country,” the EPA says in a June 5 statement.’
Diflufenican could also be part of integrated pest management and resistance management programs, the EPA added.
The ingredient is registered for use in the United Kingdom and European Union where farmers use it to manage weeds in lentils and winter cereal crops.
American ag industry organizations are confident diflufenican could be a valuable tool for producers.
The ingredient, which would be sold under the tradename Convintro in North America, “demonstrates effectiveness as an integrated wed management strategy for multiple-herbicide resistant waterhemp control,” the Weed Science Society of America said in June 2024.
The EPA is providing opportunities for the public to comment on the potential registration.
The public comment period will be open until July 7, 2025.
