WY Pesticide Applicator case studies

WY Pesticide Applicator · Put your knowledge to work in context.

Wyoming pesticide applicator certification is the state credential that allows you to legally apply restricted-use pesticides and, for commercial work, to apply pesticides for hire or as part of your job. The Wyoming Department of Agriculture administers the program under a state plan approved by the U.S. Private applicators - typically farmers and ranchers applying restricted-use products on their own or rented land - and commercial applicators, including government and institutional staff, both need certification, and commercial operations also need a certified immediate supervisor. In most cases you first pass a CORE exam covering the fundamentals that apply to every application: pesticide laws and recordkeeping, label comprehension and safety data sheets, pest identification and integrated pest management, formulations and compatibility, personal protective equipment and human safety, equipment calibration and application technique, environmental protection and off-target movement, and storage, transport, spill response, and disposal. The WY Pesticide Applicator case studies are 5 cases and about 2,236 words.
