Dicamba damage on soybeans as part of a research and demonstration plot at the UT West Tennessee AgResearch and Education Center in Jackson.


The Tennessee Department of Agriculture (TDA) has filed new rules with the Secretary of State to mitigate the risk of drift of herbicides containing dicamba. 

Among the new rules: 

*Anyone applying dicamba products must be certified as a private applicator or licensed as a pest control operator in the category of Agricultural Pest Control (AGE), and is required to keep records for such applications.

*The use of older formulations of dicamba products for the remainder of this agricultural growing season is prohibited.

*To minimize the potential for off-target movement of the product due to temperature inversion, dicamba may only be applied from 9 a.m. to 4 p.m. in the respective time zone for the location of application.

*Applying dicamba over the top of cotton after first bloom is prohibited.
