2023 Minnesota Specific Restrictions
Minnesota-specific Dicamba Herbicide Restriction to Remain in Place for 2023
2022 Minnesota Specific Restrictions
- EPA Approves 2022 Minnesota-Specific Restrictions for Dicamba Herbicide
- Date and temperature restrictions added to label
- XtendiMax With VaporGrip Technology Herbicide (EPA Reg. No: 264-1210) Minnesota Specific Label (PDF)
- Engenia Herbicide (EPA Reg. No: 7969-472) Minnesota Specific Label (PDF)
- Tavium Plus VaporGrip Technology Herbicide (EPA Reg. No: 100-1623) Minnesota Specific Label (PDF)
2022 Cutoff Date and Cutoff Temperature
Dicamba is an important tool in combating herbicide resistant weeds in Dicamba Tolerant (DT) soybeans. Products containing dicamba can cause serious damage to non-dicamba-tolerant soybeans and to other sensitive crops and non-crop plants. The MDA received more than 300 dicamba drift related reports during the 2021 growing season.
For the 2022 growing season, the MDA has worked with the U.S. Environmental Protection Agency (EPA) and the registrants of the three dicamba products, XtendiMax®, Engenia®, and Tavium® to include the following restrictions on the product labels.
- Cutoff date: Do not apply south of interstate 94 after June 12. Do not apply north of interstate 94 after June 30.
- Cutoff temperature for the entire state: Do not apply if the air temperature of the field at the time of application is over 85 degrees Fahrenheit or 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 EPA has approved these restrictions and have amended the product labels for these three dicamba products for the 2022 growing season. The amended product labels with Minnesota-specific restrictions are available on the product manufacturer’s website (Bayer, BASF, Syngenta). Check the company’s website to download the restrictions prior to application of any of these three dicamba products. The restrictions are also 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 on mandatory dicamba training can be found at the manufacturer (BASF, Bayer, Syngenta) website.
The new cutoff date (June 12th south of Interstate 94) is based primarily on the pattern of drift complaints observed in 2021 and previous years.
The federal label prohibits applications of XtendiMax, Engenia and Tavium on DT soybeans after June 30th.
In addition to the 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.
