Late Tuesday, the Environmental Protection Agency announced five year registration approval for two dicamba products and extension of a third. Bayer’s Extendimax and BASF’s Engenia received five year approvals while Syngenta’s Tavium’s registration was extended. SDSU Extension Weed Science Coordinator Paul Johnson says it’s positive the agency has approved those.
EPA Administrator Andrew Wheeler says the approval means that farmers now have the certainty they need to make plans for their 2021 growing season. The EPA dicamba registration includes some important control measures. Johnson says producers need to be aware of those and follow them.
One of the control measures requires a downwind buffer of 240 feet and 310 feet where listed species are located. Johnson doesn’t see that as much of a problem in South Dakota because of the limited number of those species.
The EPA registration for dicamba tolerant soybeans will expire in 2025. To view the new registration requirements you can go to EPA’s website.
