Indiana Pesticide License Practice Test (Free Core Exam Questions)

Preparing for the Indiana pesticide applicator exam? In Indiana, applicator certification and licensing are handled by the state pesticide regulatory agency, generally the Office of Indiana State Chemist. Like every state, Indiana requires applicators to show competency in the core (general standards) areas set out in federal rules: label comprehension, safety, environmental protection, pests, pesticides, equipment, application methods, laws, supervision, and professionalism. Most candidates also take a state laws section and one or more category exams.

Confirm current exam requirements, manuals, fees, and testing locations directly with the Office of Indiana State Chemist. This site is unofficial and not affiliated with any Indiana agency.
