As of March 15, 2022, the US Environmental Protection Agency (EPA) has registered three dicamba products for postemergence application in dicamba-tolerant (DT) soybean and dicamba-tolerant cotton. The registrations expire in December 2025 and apply to the following products:
- XtendiMax (EPA Reg. # 264-1210);
- Engenia (EPA Reg. # 7969-472);
- Tavium (EPA Reg. # 100-1623).
This new use of dicamba herbicide provides another post-emergence control option for broadleaf weeds in DT soybeans in Minnesota. This is especially important for control of weeds resistant to glyphosate and other herbicides.
