ID Pesticide Applicator study guide
ID Pesticide Applicator · Work through your exam, one topic at a time.
The Idaho Pesticide Applicator credential is issued through the Idaho State Department of Agriculture (ISDA), whose Pesticides division administers applicator licensing and certification and publishes exam information, study materials, and a list of approved online modules. It is intended for people who apply pesticides as part of their work - farm and ranch operators, crop consultants, grounds and right-of-way crews, nursery and ornamental applicators, and the technicians who apply under their direction - and who must show they can handle pesticides lawfully, safely, and effectively. The ID Pesticide Applicator study guide has 5 sections and about 2,067 words.
