Tractor applying pesticide in a field of soybeansDicamba is a selective and systemic herbicide that is used for post-emergence control of broadleaf weeds in a variety of food and feed crops, as well as turfgrass.

On October 27, 2020, the US Environmental Protection Agency (EPA) registered two end-use dicamba products and extended the registration for one dicamba product for over-the-top (OTT) application in dicamba-tolerant soybean and dicamba-tolerant cotton until December 2025. The products include:

  • XtendiMax (EPA Reg. # 264-1210), new registration;
  • Engenia (EPA Reg. # 7969-472), new registration;
  • Tavium (EPA Reg. # 100-1623), extended registration.

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.
