Dicamba Updates

The Arkansas State Plant Board (ASPB) investigates in response to complaints or allegations filed by citizens. Each year, the ASPB handles a significant number of complaints relating to alleged chemical misuse; the complaints may name a suspected chemical, but until inspectors are able to get on site and diagnose based on symptomology and collect records, there is no way to make a determination on the chemicals used. Since 2015, the ASPB has worked to investigate and in some cases prosecute for a higher than normal volume of dicamba-related complaints.

Dicamba is a selective herbicide in the chlorophenoxy family of chemicals. It comes in several salt formulations and an acid formulation. It is a common herbicide used in getting rid of weeds and woody plants.

Official statement from the Arkansas Agriculture Department regarding Arkansas dicamba regulations, 4/30/2018: Following Orders issued by the Arkansas Supreme Court, the Agriculture Department’s State Plant Board will enforce Arkansas dicamba-related regulations in all counties. The use of dicamba products is prohibited in Arkansas through October 31. Regulations include exemptions for the use of dicamba in pastures, rangeland, turf, ornamental, direct injection for forestry, and home use. Find Arkansas dicamba-related regulations, which are part of the Arkansas Pesticide Use and Application Regulations, here.
