Dicamba OTT Update 3/1/2025
On February 6, 2024, the U.S. District Court of Arizona vacated the federal registrations of three over-the-top (OTT) dicamba products, XtendiMax® (EPA Reg. No. 264-1210), Engenia® (EPA Reg. No. 7969-472), and Tavium® (EPA Reg. No. 100-1623). These products were previously registered with the Environmental Protection Agency (EPA) for over-the-top (OTT) use on dicamba-tolerant (DT) soybeans and cotton. The court decision makes it illegal to sell, distribute, or use these products in the United States for the 2025 growing season.
As a result of the court decision, XtendiMax®, Engenia®, and Tavium® products are no longer registered for use in Georgia in 2025. Georgia’s Pesticide Control Act prohibits the sale, distribution, or use of pesticides that are not registered within the state (Georgia Pesticide Control Act O.C.G.A 2-7-62). Violations may result in enforcement actions.
No dicamba herbicide has been approved for use in-crop for the 2025 spray season at this time. Other dicamba products currently registered with the Georgia Department of Agriculture (GDA) for use in agricultural and non-agricultural sites, including fallow cropland and pastures are not impacted by the court ruling.
Following the 2024 court ruling that vacated previous registrations, the pesticide registrants submitted new product proposals that include OTT application of dicamba. The revised labels propose new use patterns and stricter restrictions aimed at reducing off-target movement and crop damage. Because the applications involved a new use pattern for dicamba, the EPA opened a 30-day public comment period on these proposed products. With the public comment periods for these applications now closed, the EPA is now reviewing the submitted comments and evaluating the submissions with the proposed label changes. Should EPA determine that these applications meet the standard for registration under the Federal Insecticide, Fungicide, and Rodenticide Act, the EPA will provide a separate opportunity for public comment on the proposed decision at a future time. The future availability of these products will depend on EPA’s re-registration decisions.
