In Minnesota, waterhemp has evolved resistance to several herbicide classes (for example, glyphosate, ALS, PPO herbicides). Growers can use this technology in DT soybeans to control herbicide-resistant weeds such as waterhemp.
Dicamba is a highly volatile chemical that can damage non-target plant species through spray drift and/or volatilization (vapor drift). Dicamba products have the potential to cause serious damage to sensitive plants species such as non-dicamba-tolerant soybeans, grapes, trees, ornamentals, etc.

During the 2022 growing season, the MDA worked with the 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 the three dicamba products listed above since 2022. These restrictions are valid until December 2025. The amended product labels with Minnesota-specific restrictions are also available on the product manufacturer’s website (Bayer, BASF, Syngenta). If the restrictions are not part of the container label, 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.
If you are planning to use one of the RUP dicamba products, you must attend auxin/dicamba mandatory training offered by dicamba registrants (Bayer, BASF, Syngenta). In addition, applicators must also follow the requirements of the Minnesota Pesticide Control Law. Other important control measures include:
- Requiring an approved pH-buffering agent (also called a Volatility Reduction Agent or VRA) to be tank mixed with the dicamba products prior to any over the top (post emergence) application.
- Requiring a 240 feet downwind buffer between the last treated row and the nearest downwind field/area edge.
- Tavium application is prohibited after V4 growth stage and XtenidMax application is prohibited after R1 growth stage.

Federal label requires, a 310 feet buffer downwind buffer between the last treated row and the nearest downwind field/area edge in areas where listed endangered species are located. In addition, a 57 ft buffer on all other sides of field must be maintained in areas with listed endangered species. The applicator must also follow the measures contained in the Endangered Species Protection Bulletin for the area in which applicator is applying the product. They must obtain Bulletins no more than six months before using the product.
It is a federal offense to use any pesticide in a manner that results in the death of an endangered species.

The MDA encourages reporting of any suspected pesticide damage. You can begin the formal complaint process by calling 651-201-6333 between 8:00 AM and 4:00 PM Monday through Friday or by submitting an online dicamba complaint form.
To submit a report of dicamba damage to the manufacturers use the following contact information:
- Bayer (XtendiMax) – 1-844-RRXTEND (779-8363)
- BASF (Engenia) – 1-800-832-HELP (4357)
- Syngenta (Tavium) – 1-866-Syngent(a) (866-796-4368)

Dicamba is a selective, systemic, and plant growth regulator herbicide primarily used for post emergence broadleaf weed control (for example, waterhemp, ragweed, horseweed) in a variety of crops, residential areas, and other sites. Dicamba herbicide belongs to Group 4 site-of-action.
Dicamba has long been used in agricultural and nonagricultural herbicide products. In Oct 2020, the United States Environmental Protection Agency (EPA) registered two end-use dicamba products XtendiMax® with VaporGrip® Technology (EPA Reg. No. 264-1210, Bayer), Engenia® (EPA Reg. No. 7969-472, BASF) until 2025 and extended the registration for dicamba product Tavium® Plus VaporGrip® Technology (EPA Reg. No. 100-1623, Syngenta) until 2025. These products are for applications to dicamba-tolerant soybeans and dicamba-tolerant cotton only.
