Published January 12, 2026 · Parkinson's Lawsuit Help
Paraquat and Roundup are the two most prominent herbicide mass torts in the United States. They are often conflated. They are different cases, against different defendants, for different injuries — though some claimants may have both.
Injury
Paraquat litigation centers on Parkinson's disease. Roundup litigation centers on non-Hodgkin lymphoma (NHL). Different organ system, different disease, different evidence.
Defendants
Paraquat: Syngenta AG (manufacturer) and Chevron U.S.A. (U.S. distributor). Roundup: Monsanto (now owned by Bayer AG).
MDL
Paraquat: MDL 3004 in the Southern District of Illinois. Roundup: MDL 2741 in the Northern District of California.
State court hubs
Paraquat: Philadelphia Court of Common Pleas mass tort program (~1,799 cases). Roundup: California state court (San Francisco Superior Court) has hosted major trials.
Settlement history
Roundup: Bayer agreed to a multi-billion-dollar settlement framework starting in 2020, with significant ongoing trial activity. Paraquat: Syngenta announced a settlement framework in April 2025, with the first Philadelphia bellwether settling on the courthouse steps in January 2026.
Can you have both claims?
Yes, if you were exposed to both herbicides and have both injuries. Many farmworkers used both. The claims are evaluated separately — eligibility for one does not affect the other.
