Office of Indiana State Chemist - Pesticide Section


The pesticide section of OISC regulates the distribution and application of pesticides in the State of Indiana. The pesticide section is charged with the administration and enforcement of Indiana pesticide laws (I.C. 15-16-4 and I.C. 15-16-5) and also represents the U.S. Environmental Protection Agency (EPA) in Indiana for the purpose of enforcing many provisions of federal pesticide law.

The mission of the Office of Indiana State Chemist Pesticide Section is to protect the public and the environment by ensuring that pesticide products distributed within the state are properly formulated and labeled and that individuals who apply pesticides have met minimum competency standards, when required, and apply those pesticides without causing harm to people or property.
