EPA's Recently Announced Changes to Dicamba Label 2019

Among the changes is a new definition of who is legally allowed to handle dicamba. Under federal law, only LICENSED APPLICATORS can handle or apply dicamba. The applicator requirement on the dicamba labels means that the person doing the application must be certified by the State of South Dakota as a licensed Commercial Applicator or Private Applicator. Non-certified personnel, may NOT perform any activities with dicamba products, including mixing or loading.

Further state-specific guidelines are coming from the South Dakota Department Agriculture (SDDA). The South Dakota label will read: CUTOFF DATE: DO NOT apply this product in dicamba tolerant soybeans after either June 30, 45 days after planting, or R1 (beginning bloom), whichever comes first. SDDA is requesting a 24C for the cutoff date since 40% of the 2018 dicamba drift investigations had application dates after July 1st. In addition, a short exam will be required as part of the annual Dicamba training.

Please help spread the word. Many applicators incorrectly believe that last year's dicamba training suffices for this year and IT DOES NOT. The labels require applicators to attend annual training. The dicamba registrants also plan to have on-line training available at some point, but the classroom training enables interaction and Q & A on the new label requirements.

Information about Dicamba products and labels can be found on the SDDA website at https://sdda.sd.gov/ag-services/dicamba/default.aspx and the EPA’s Frequently Asked Questions here.
