I'm not sure exactly what materials you want. If you are looking to find out how to be a certified pesticide applicator, here is a link to our general certification brochure.
This brochure will explain the differences between private, commercial, and public applicators and what you need to do to become an applicator. Also included is information on how you need to maintain your certification. Contact information for the Pennsylvania Department of Agriculture is provided.
