Abstract
(HB6114 · 103rd Legislature) Agriculture: pesticides; use of herbicides that contain paraquat dichloride; prohibit. Amends 1994 PA 451 (MCL 324.101 - 324.90106) by adding subpt. 3 to pt. 147. Latest action (2026-06-23): Bill Electronically Reproduced 06/18/2026
Why this matters
Paraquat dichloride is a restricted-use herbicide linked to acute poisoning and, in epidemiological studies, to Parkinson’s disease, and it is already banned in the EU and several other jurisdictions. A Michigan statutory prohibition would shift growers to alternative weed-control chemistries and add the state to a small but growing group restricting the compound beyond federal EPA rules. The measure sits at the intersection of agricultural practice, pesticide regulation, and public/environmental health policy in Michigan.
