The Idaho State Department of Agriculture registers all pesticide for use and distribution in the state of Idaho.
The registered pesticide database is on the ISDA webpage. You can search that database with several options.
ISDA also registers pesticides for special circumstances:
- Special Local Needs (SLN or Section 24C registrations)
- Emergency exemptions from FIFRA also called Section 18 registrations
The U.S. Environmental Protection Agency regulates pesticides. Their website has information on pesticide science and policy.
