Dicamba Herbicide Information

The information below contains links to various locations to provide you with additional information for the use of certain dicamba herbicide formulations. To apply Engenia, Tavium, and/or XtendiMax you must have valid pesticide certification and have attended an approved dicamba training program. Annual training is required to use the dicamba products designated for use on Dicamba Resistant crops.

In regard of the May 15th dicamba rule.  For May 15-October 1 dicamba rule is no longer a rule as of 2024.  It was redacted from the Tennessee Pesticide Rules and Laws late last year.  Please refer to and follow all label instructions for all dicamba products and over-the-top dicamba products.  If you have any questions, please contact Chad Hayes at the Tennessee Department of Agriculture email:chad.hayes@tn.gov or call 615-837-5148.
