Extension Programs
- Pesticide Applicator Program - involves education and training of Montana's 8,000 farmers and ranchers who need a license to purchase and apply restricted use pesticides. To facilitate implementation of this program county Extension agents and specialists are involved to provide up-to-date information on various aspects of the selection and use of pesticides for the myriad pests that attack crop and range.
- Pesticide Impact Assessment Program - this program acquires data on pesticide usage in Montana and determines which pesticides are important for protecting, crop, range, and livestock. Pesticide use surveys have been conducted on a number of commodities inthe state and these data are used to support registrations of these pesticides.
