Serving the citizens of Arkansas and the agricultural and business communities by providing information and unbiased enforcement of laws and regulations set by the Arkansas State Plant Board
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 Alleged Pesticide Misuse/Drift Investigation or call 501-225-1598 and ask to speak to the Pesticide Division.
