2021 Cutoff Date

The Environmental Protection Agency (EPA) has set June 30 as the application cutoff date for the dicamba herbicides XtendiMax, Engenia and Tavium in 2021. The federal label prohibits applications of these three dicamba products after June 30th.

From 2018 to 2020, the MDA set June 20 as the annual cutoff date for registered dicamba products to curb off-site movement. This date was based on research and pesticide misuse complaints. At the time, there was not a cutoff date included on the federal label.

In addition to the June 30 cutoff date, Xtendimax and Tavium have crop growth stage cutoffs.

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.
