Pesticide Applicator: FIFRA, OAR, ORS, and WPS - The ABC's of Pesticide Law in Oregon

One of the primary responsibilities of a pesticide applicator is to know, understand, and comply with federal and state regulations regarding pesticide use. Legal requirements today are designed to allow industry professionals to maximize the benefits of sensible pesticide use while minimizing the harm that pesticides can cause to humans, wildlife, and the environment.

Sometimes, state regulations are more restrictive than federal standards, and therefore an examination of state law is necessary to have a complete understanding of the legal obligations of pesticide applicators in Oregon. In this course, you will examine the federal laws and regulations that protect yourself, the public, and environment from the adverse effects of pesticides. You will also examine the state laws in Oregon.

If you are currently a licensed pesticide applicator or consultant, you will earn one (1) continuing education credit by completing this course.

This course can also help you prepare for your certification exams if you seek to become a licensed apprentice, a commercial applicator, a private applicator, a public applicator, or a pesticide consultant. Learning materials in this course include information covered in the National Pesticide Applicator Certification Core Manual.
