The Tennessee Department of Agriculture is taking measures to mitigate the risk of drift of herbicides containing dicamba.

State and federal laws mandate applicators strictly follow label directions and consider the weather and potential for temperature inversions when applying any herbicide. Any suspected misapplication should be reported immediately to TDA at 800-628-2631 or 615-837-5148. The department will take appropriate enforcement action for any misapplication, including but not limited to suspension or revocation of a certificate and state penalties up to $1,500 per violation per acre where application occurred, in addition to federal penalties and possible criminal prosecution.

To purchase and apply a Restricted Use Pesticide (RUP), you must become commercially certified by testing in 1 of the 15 certification categories or privately certified by taking the initial training through the University of Tennessee Agricultural Extension Service. You must also submit the $25 fee, including a copy of the triplet form verifying the private applicator training.

In addition, if you are applying dicamba products you would need to provide a copy of your certificate for the dicamba training to:
