Dicamba Training and Resources

This past fall The Environmental Protection Agency announced the re-registration of several in-season dicamba products, with important label updates that affect your options for managing Roundup Ready 2 Xtend® and XtendFlex® soybeans systems in 2021. Click here to see what you need to know to manage your 2021 season’s acres.

From 2018 to 2020, the MDA had placed an annual June 20 cutoff date on registered dicamba products based on research and pesticide misuse complaints – a cutoff date that was not included on the federal label – to curb off-site movement; however, the EPA has now limited states’ abilities to impose further application restrictions.

New federal label requirements for the products include:

• An application cutoff date of June 30 (unless growth stage cutoff comes first)
• 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

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

The MDA is also requiring product makers provide approved education and training of applicators and provide more Minnesota-specific data on the use of dicamba to inform future department decisions.
