Paraquat dichloride (paraquat) is a restricted use pesticide due to its extreme acute toxicity. Only certified pesticide applicators may legally mix, load, or apply paraquat products; use by uncertified persons is prohibited, even under the supervision of a certified applicator.
Paraquat is the active ingredient in products such as Gramoxone, Firestorm, Helmquat, and Parazone, among others.
Because accidental ingestion, dermal exposure, and inhalation have resulted in fatalities and severe injuries, EPA issued the Paraquat Dichloride Human Health Mitigation Decision, which requires:
- Stronger label warnings and supplemental toxicity materials
- Mandatory paraquat‑specific training for certified applicators
- Closed‑system packaging for non‑bulk (<120‑gallon) containers
- Certified applicator‑only use (no supervised use by uncertified individuals)
Training Requirement
Certified applicators must complete EPA‑approved paraquat training before mixing, loading, or applying paraquat, and every three years thereafter.
The training covers toxicity, label requirements, safe handling, and consequences of misuse.
Online Paraquat Training (EPA‑Approved)
EPA‑approved online training is available through Syngenta Crop Protection’s Paraquat Training platform.
