The U.S. Environmental Protection Agency (EPA) recently announced a new five-year registration for two dicamba products — XtendiMax with VaporGrip Technology and Engenia Herbicide. Through this action, EPA also extended the registration for Tavium Plus VaporGrip Technology.
All three registrations include new control measures to ensure products are used effectively while protecting the environment. Measures protect non-target plants and animals, as well as other crops intolerant to dicamba. Registrations expire in 2025.
Alabama Farmers Federation’s Carla Hornady, divisions director for cotton and soybeans, said farmers appreciate the certainty these new registrations provide as harvest wraps up and planting season steadily approaches.
“Dicamba is the most effective control for invasive plants, like pigweed,” Hornady said. “Because of the results, cotton and soybean farmers have invested in dicamba-resistant crops as part of their conservation tillage practices.”
Important EPA control measures include:
- Requiring an approved pH-buffering agent be tank mixed with over-the-top dicamba products prior to all applications to control volatility.
- Requiring a downwind buffer of 240 feet and 310 feet in areas where listed species are located.
- Prohibiting over-the-top application of dicamba on soybeans after June 30 and cotton after July 30.
- Simplifying the label and use directions so growers can more easily determine when and how to properly apply dicamba.
