Published March 5, 2026 · Parkinson's Lawsuit Help
In March 2026, Syngenta announced that it would discontinue U.S. production of paraquat. The company framed the decision in commercial terms. Plaintiffs' counsel framed it in litigation terms. Both are right — and neither changes the fact that anyone exposed before March 2026 and diagnosed with Parkinson's disease retains a claim.
What was announced
Syngenta's announcement covers U.S. manufacturing of paraquat. The company did not concede liability for past exposures, and it did not commit to a global voluntary withdrawal. Existing stocks of paraquat-based herbicides will continue to be sold and applied in the United States until exhausted, subject to EPA Restricted Use rules.
Why now
Industry analysts point to mounting litigation costs, reputational pressure, and falling demand as paraquat alternatives proliferate. The April 2025 settlement framework and the January 2026 Philadelphia bellwether settlement made the U.S. paraquat business meaningfully less attractive on a forward-looking basis.
Liability impact for existing claims
Discontinuation of production does not extinguish liability for past exposures. The Parkinson's claims pending in MDL 3004 and the Philadelphia mass tort program all involve historical exposures — most claimants were exposed decades before diagnosis. The discontinuation is forward-looking and does not provide a defense to backward-looking claims.
What it means for new filings
Statutes of limitations vary by state and by accrual rule. Many paraquat cases run on discovery rules — the clock starts when the claimant knew or should have known of the link between exposure and disease. New filings remain timely in most jurisdictions, but the safe move is to confirm with counsel as soon as possible.
