Louisiana Regulations on Applications of 2,4-D Herbicide
The applications of 2,4-D herbicide in certain parishes, in accordance with the current regulations and labels, have not been sufficient to control drift onto non-target areas.  Drift onto non-target areas has adversely affected other crops, particularly cotton.  Therefore, the Louisiana Dept. of Agriculture and Forestry has determined that rules implementing further state restrictions on the application of 2,4-D herbicide and products containing 2,4-D are necessary to alleviate adverse affects from drift onto these non-target areas. 
The complete regulation on the state restrictions of 2,4-D herbicide and other listed pesticides in listed areas in Louisiana can be found at Sec. 143, page 24 in the Pesticide Rules and Regulation.
The application of 2,4-D herbicide at certain times and in certain areas of Louisiana requires issuance of a waiver, permit, or written authorization from the Louisiana Dept. of Agriculture and Forestry.  For detailed information on the different 2,4-D herbicide restriction, click on one of the maps listed below.
