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.
To request an investigation due to suspected dicamba symptomology, complete the Request for Suspected Dicamba Investigation or call 501-225-1598 and ask to speak to the Pesticide Division.
