On Oct 27, 2020, The United States Environmental Protection Agency (USEPA)
announced a new 5-year registration for XtendiMax® and Engenia, and re-registered
Tavium (a premix of dicamba and S-metolachlor).
To reduce off-target movement of dicamba, USEPA’s 2020 registration features important control measures, including:
- Requiring a downwind buffer of 240 feet and 310 feet in areas where endangered species are located. The use of hooded sprayers during application may reduce certain buffer requirements.
- Requiring an approved pH-buffering agent (also called a Volatility Reduction Agent or VRA) be tank mixed with dicamba products to reduce volatility.
- Prohibiting dicamba application in Roundup Ready 2 Xtend® soybean after June 30, regardless of soybean growth stage.
- Simplifying the label and use directions so that growers can more easily determine when and how to properly apply dicamba.
