Procedures for Investigating Possible Pesticide Misuse

The Missouri Department of Agriculture is responsible for regulating the use of pesticides in the state of Missouri. This is established in Sections 281.005 to 115 (RSMo) of the Missouri Pesticide Use Act.

Due to the volume of dicamba-related complaints, the Department may limit the number of complaints formally investigated.

Investigations may include:

  1. Taking a statement from the person that filed the complaint regarding possible pesticide misuse.
  2. Taking a statement from the person(s) accused of possible pesticide misuse.
  3. Collecting physical samples of items possibly contaminated by the pesticide as well as documentary evidence such as written papers, invoices, contracts, photographs, audio recordings, and video or printed emails. (NOTE: Laboratory analysis of physical samples can take 30-60 days or longer).
  4. Submitting a narrative report and documentary evidence related to an alleged pesticide misuse incident for review of case.

The Missouri Department of Agriculture does NOT determine yield loss or property damage loss and does NOT order payment of any kind regarding damages or losses. Once the investigation is closed, any party involved in the investigation may submit a written request for a copy of the investigation report.

Any questions may be directed to the Bureau of Pesticide Control at (573) 751-5504. Written requests must be submitted to:
