Pesticide Enforcement

Stefan P. Parnay, Agriculture, Weights and Measures - Marin County

The Marin County Department of Agriculture/Weights and Measures oversees the use of pesticides in Marin County. We are committed to protecting our community and beautiful environment by ensuring pesticides are handled and stored properly, and commercial applicators are trained and licensed.

  • Whenever pesticides are being used (or stored) at our homes, along our roads, or on our farms, we have the authority to go there and conduct inspections. These inspections help ensure that California-approved pesticides are being used safely and stored properly.
  • We make sure that commercial pesticide users are trained and licensed to conduct their work safely.
  • We immediately investigate pesticide related complaints and potential illnesses to determine what happened so that we can help prevent it from happening again.
  • “Pesticide” is a general term that includes “Herbicides” (weed control), “Insecticides” (insect control), “Fungicides” (for fungus control), “Rodenticides” (rodent control), etc.
