EPA requests updated dicamba data in preparation for registration decision

The EPA is collecting in-depth information for their next decision on dicamba registration.

The agency sent letters to the four dicamba registrants; BASF, Bayer, Corteva and Syngenta requesting all information recorded on the adverse effects of dicamba products in the past year, to ensure EPA has all relevant information to decide on re-registration of dicamba and label restrictions.

EPA cites news reports indicating that even with the more restrictive label and registration requirements implemented in October 2020, approved dicamba products for over-the-top application on dicamba tolerant soybeans and cotton continue to appear in reports of alleged adverse accidents.

The companies have been given ten days to provide all studies and reports on adverse effects including plant damage which occurred in any country since October 2020. The agency has also requested all information on effects to non-dicamba tolerant species, total quantities sold, and all data and in-progress studies on off-target movement, toxicity, and development of plant resistance to dicamba. All is subject to reporting under FIFRA, the nation’s pesticide law. Any information already reported to EPA need not be submitted again.

Although Corteva stopped selling their dicamba product FeXapan in February, they received the letter because the company’s registration is still current with EPA.
