EPA Approves 2022 Minnesota-specific restrictions for dicamba herbicide

The U.S. Environmental Protection Agency (EPA) has given approval to the Minnesota Department of Agriculture’s (MDA) state-specific use restrictions for three dicamba herbicide products during the 2022 growing season in Minnesota. The restrictions are aimed at curbing off-site movement of the products. The affected dicamba formulations are Engenia by BASF, Tavium by Syngenta, and XtendiMax by Bayer. These are the only three dicamba products labeled for use on dicamba-tolerant soybeans.

Date and temperature restrictions were added to the dicamba label as follows:

DATE CUTOFF: No application shall be made south of Interstate 94 after June 12, 2022. North of Interstate 94, use is prohibited after June 30, 2022.

TEMPERATURE CUTOFF STATEWIDE: No application shall be made if the air temperature of the field at the time of application is over 85 degrees Fahrenheit or if the National Weather Service’s forecasted high temperature for the nearest available location for the day exceeds 85 degrees Fahrenheit. Forecasted temperature must be recorded at the start of the application.

The product label with these EPA approved Minnesota-specific restrictions will be available on the product manufacturer’s website (Bayer, BASF, or Syngenta). Check the company’s website to download the restrictions prior to application of any of these three dicamba products.

The restrictions will also be promoted through the mandatory dicamba specific training, required for anyone applying one of the approved products, on the manufacturer’s website. Compliance with these Minnesota-specific restrictions and other restrictions listed on the product label is mandatory. Information about dicamba use and training is available on the product label and product manufacturer’s website at (Training dates will be updated as they become available):

BASF - Information on training can be found at

Bayer link for the mandatory training options is available at the following site under the Training and Stewardship section

Other federal requirements for the products that appear on the 2022 labels include:
  • Requiring an approved pH-buffering agent, also known as a volatility reducing agent, be tank mixed with dicamba products prior to all applications
  • Requiring a downwind buffer of 240 feet and 310 feet in areas where listed endangered species are located
  • Additional recordkeeping items (record keeping forms are available for download at company websites)
  • In addition to the cutoff date, Xtendimax and Tavium have crop growth stage cutoffs.
In Minnesota, Engenia, Tavium, and XtendiMax formulations of dicamba are approved for use on dicamba-tolerant soybeans only and are “Restricted Use Pesticides.” The dicamba products are only for retail sale to and use by certified applicators.

Pesticide product registrations are renewed on an annual basis in Minnesota.
