New 2019 State-Specific Restrictions

The MDA has a state-specific restriction for the use of the herbicide dicamba in Minnesota for the 2019 growing season.

  • Cutoff date: Do not apply after June 20, 2019. Setting an application cutoff date of June 20 is again expected to help reduce the potential for damage to neighboring crops and vegetation.
  • There will be no temperature application restriction in 2019.

In Minnesota, the XtendiMax, Engenia, and FeXapan formulations of dicamba are “Restricted Use Pesticides” for retail sale to and for use only by Certified Applicators.

What is Dicamba?

Dicamba is a selective herbicide used for post-emergent control of broadleaf weeds in corn, soybeans, and a variety of other food and feed crops in Minnesota. It can also be used for weed control in residential areas.

Dicamba is a highly volatile chemical that can damage non-target plant species through spray drift and/or volatilization (vapor drift). Misuse of products containing this active ingredient may cause serious damage to non-dicamba-tolerant (non-DT) soybeans and to other sensitive crop and non-crop plants.
