40 CFR Part 171 · Restricted Use Pesticides

Pesticide applicator certification:
the license behind the restricted label

5 YR FEDERAL CLOCK · EXAM OR CE TO RENEW

To use or supervise restricted use pesticides you need applicator certification: private if you produce an agricultural commodity, commercial in one of 16 federal categories for everyone else. You must be 18, pass a written exam (or an approved training program for private applicators where your state allows it), and renew within five years by exam or continuing education. The framework is federal, your state lead agency runs it, and every fact on this site is verified against 40 CFR Part 171.
