Private Pesticide Applicators

The goals of the Pesticide Applicator Program are to ensure that private and commercial pesticide applicators have the requisite knowledge to handle and apply pesticides, and to ensure that pesticides are applied in a manner which reduces unnecessary associated hazards. The program covers the certification of private pesticide applicators who use restricted use pesticides, commercial applicators, and some businesses and public agencies that do their own pesticide applications. All persons in the state who use pesticides are regulated by the Colorado Department of Agriculture.


To meet the goals of the program, the Department conducts exams, issues licenses, and requires technician training and continuing education. In addition, the Department enforces the federal Worker Protection Standard; conducts pesticide use inspections checking for proper maintenance of equipment, proper application, storage, and disposal of pesticides; and investigates complaints about the misapplication of pesticides.
