UPDATE: The Environmental Protection Agency Provides Further Guidance Regarding the Previous Suspension of All Sales and Application of Dicamba Products

June 10, 2020

BROOKINGS, S.D. - On June 3, the United States Court of Appeals for the Ninth Circuit issued a decision to vacate the registration of three dicamba products including Xtendimax, Engenia, and FeXapan for over the top use on soybeans. As of June 8, the Environmental Protection Agency (EPA) provided the following information regarding the court order:

  • Producers with approved dicamba products currently on-hand are allowed to apply them 
  • Commercial applicators with approved dicamba products currently on-hand are approved to apply them for customers 

South Dakota applicators should follow and adhere to all requirements of the previously registered 24c label for Xtendimax, Engenia and FeXapan products. Soybeans can be sprayed up to 45 days after planting or before the R1 growth stage, or by June 30, whichever comes first. Read, understand, and follow all label information.

For more information on soybean chemical recommendations, refer to the 2020 South Dakota Soybean Pest Management Guide.
