As a result of the February 6, 2024 ruling by the U.S. District Court of Arizona, and the February 14, 2024 order issued by the U.S. Environmental Protection Agency (EPA), the federal and state registrations of dicamba herbicide products that are labeled for over-the-top use have been revoked in New Mexico, Arizona and Texas. The last day allowed for the sale and distribution of XtendiMax, Engenia or Tavium for use on dicamba-tolerant soybeans is May 31, 2024. These products cannot be used on dicamba-tolerant soybeans after June 30, 2024. The last day allowed for the sale and distribution of XtendiMax, Engenia or Tavium for use on dicamba-tolerant cotton is June 30, 2024. These products cannot be used on dicamba-tolerant cotton after July 30, 2024. Growers should contact their pesticide distributor to determine the return policy for excess dicamba products.
For restrictions on the sales, distribution, and use of these formerly registered products, visit EPA’s Existing Stocks Order for Dicamba Products Previously Registered for Over-the-Top Use on Dicamba-Tolerant Cotton and Soybean.
