Welcome to Pesticide Safety Education! OSU Extension is directly involved with private pesticide applicator training in Ohio. As a new, county OSU Extension educator, you will be helping farmers obtain their private pesticide applicator license to purchase restricted use products for their farm. You'll also be conducting recertification training every year for farmers who already have their private pesticide applicator license. Our goal is to protect human health and the environment by providing education programs on the safe and effective use of pesticides.
