Gramoxone Phaseout Leaves Growers Reviewing Paraquat Weed Options

Growers should work with local agronomists, check state registrations, and follow all restricted-use label requirements.

NASHVILLE, TENN. (RFD NEWS) — Growers who rely on Gramoxone for burndown, desiccation, and contact weed control may need to review supply plans before the end of 2026. South Dakota State University Extension says Syngenta will stop global production of Gramoxone by June 30 and end sales when current supplies are depleted or by December 31.

Gramoxone contains paraquat dichloride, a non-selective Group 22 herbicide used in row crops, orchards, rights-of-way, and pre-harvest desiccation in many row crops.

The change does not remove all paraquat products from the market. SDSU says other manufacturers still have paraquat products registered, meaning availability may continue where registrations remain active.

Regulatory pressure is still part of the story. California says Syngenta voluntarily canceled Gramoxone SL 3.0 registration there, effective April 1, while other paraquat products remain under reevaluation.

Growers should work with local agronomists, check state registrations, and follow all restricted-use label requirements.

Farm-Level Takeaway: Gramoxone is being phased out, but paraquat planning now depends on product availability, state registrations, and safe-use requirements.
