Sale, distribution, or use of existing stock of XtendiMax®, Engenia®, and Tavium® is no longer allowed. However, the EPA issued an order. on February 14, 2024 (revised on March 12, 2024), that allows existing stocks of these products to be distributed solely for the purpose of returning them to the registrants or for proper disposal, with no end date. Individuals and entities, including end users possessing these stocks (excluding the registrants), are allowed to return them to the registrants or dispose of them in accordance with all applicable federal, state, and local waste disposal regulations.
If you have OTT dicamba products (i.e., XtendiMax®, Engenia®, and Tavium®) that need to be disposed of, check with your dealer, co-operative, or ag retailer to see if they will take back products. If they will not, please use the MDA's Waste Pesticide Collection Program. For larger volumes (over 300 pounds), call the MDA’s Jane Boerboom at 612-214-6843.
OTT dicamba was used to control broadleaf weeds, particularly those resistant to glyphosate and other herbicides, in DT soybeans in Minnesota. The loss of this tool emphasizes the need for diversified weed management, including a combination of preemergence residual and postemergence herbicides with multiple sites-of-action to reduce resistance development and broaden weed control. While not specific to Minnesota, the University Extension crop and pest management guides below provide valuable information on various weed control options. Always consult the MDA's registered product search tool to verify that any pesticide products you plan to use is registered in Minnesota. Always read and follow label instructions carefully before using any pesticide. The Label Is The Law!
Both the MDA and Minnesota Pollution Control Agency (MPCA) have roles in regulating land application of biosolids (PDF | MPCA) and industrial byproducts (PDF | MPCA). MPCA performs all the permitting and site approval (when applicable) for land application of these materials. The MDA registers products comprised of these materials to be sold in the state of Minnesota. These processes are separate, and both may be required for products sold in Minnesota to be compliant with state laws.
Land application of biosolids (MPCA) is a common practice in Minnesota. Biosolids are a nutrient-rich component of municipal wastewater treatment commonly used as a soil amendment. During wastewater treatment liquids are separated from solids. The solids portion of wastewater treatment are then further biologically or chemically treated to produce a semisolid known as biosolids. When biosolids are applied to the land at appropriate rates, they provide a nutrient addition and improved soil structure.
An industrial byproduct (MPCA), also known as an IBP, is a byproduct of an industrial, commercial, mining, or agricultural operation. IBPs from food, beverage, and agricultural operations such as vegetable, dairy, and meat processing wastes typically contain nutrients that make them good candidates for land application.

Application Fee
- The annual application fee for registration of a specialty fertilizer is $100 for each brand and grade to be sold or distributed.
- Application fees are nonrefundable. Therefore, we recommend that copies of labels or proposed labels be submitted to us for review and comment prior to submission of a registration application. This may prevent the loss of fees in case a product registration is denied
Registration Period
- The registration period is effective until January 1 following the date of issuance or approval. The application for renewal of a registration of a product must be filed with us on or before December 31 the previous year or an additional application (penalty) fee of one-half of the application fee ($50) is due.
- A product registration is not transferable from one person to another or from the ownership to whom the registration is issued to another ownership
Registration Discontinuation
Specialty fertilizers are given two years to clear the channel of trade. Use one of the following two options to discontinue the registration of specialty fertilizers:
- Complete the two-year discontinuation process by registering a specialty fertilizer for two years after distribution or sale has ceased.
- Provide documentation showing that no specialty fertilizer product has been distributed or sold into or within the state for the last two years.
