Weed Scientist Peter Dotray, Texas Tech Univerisity and Texas A&M AgriLIfe Extension, Lubbock, discusses how the dicamba herbicide Tavium differs from the three banned dicambas. He also discusses the future of weed management.
The United States Court of Appeals for the Ninth Circuit issued a ruling June 3 vacating the federal registration for Xtendimax, FeXapan, and Engenia. June 8, an EPA order addressed the sale, distribution, and use of existing stocks of dicamba.
The order first states that the distribution or sale by any person is generally prohibited except for ensuring proper disposal or return to the registrant.
The order also states that growers and commercial applicators may use existing stocks that were in their possession on June 3, 2020, the effective date of the court decision. Such use must be consistent with the products' previously approved labels, and may not continue after July 31, 2020.
