Paraquat Lawsuit FAQ

Paraquat dichloride is a non-selective contact herbicide first commercialized by Imperial Chemical Industries (now Syngenta AG) in the 1960s. It is sold under brand names including Gramoxone, Blanco, Devour, Firestorm, Helmquat, Para-Shot 30, Parazone, and Tota-col. The U.S. EPA classifies paraquat as Restricted Use — only certified applicators may purchase or apply it.

Paraquat is a redox-cycling compound that generates reactive oxygen species inside cells. Dopaminergic neurons in the substantia nigra of the brain are unusually vulnerable to oxidative stress, and progressive loss of these neurons is what defines Parkinson's disease. Both animal studies and human epidemiology (including the Agricultural Health Study) support a causal link.

Farmers, hired farmworkers, licensed pesticide applicators, mixers, loaders, crop-dusting pilots, equipment maintenance workers, and people who lived near treated agricultural fields who have been diagnosed with Parkinson's disease — or who have a strong clinical suspicion of Parkinson's — may qualify. Eligibility is fact-specific.

No. Pennsylvania's consent-by-registration jurisdiction (upheld after the U.S. Supreme Court declined to review Syngenta's challenge in October 2025) permits non-PA residents to sue Syngenta and Chevron in Pennsylvania state court. Pennsylvania residents always qualify.

Multidistrict Litigation No. 3004 — In re: Paraquat Products Liability Litigation — is the federal consolidation of paraquat Parkinson's cases pending before Chief Judge Nancy J. Rosenstengel in the Southern District of Illinois. Thousands of cases are pending. An MDL is not a class action; each plaintiff retains an individual claim and an individual recovery.

The Philadelphia Court of Common Pleas operates a Complex Litigation Center that administers mass tort dockets. Its paraquat program before Judge Joshua Roberts currently hosts approximately 1,799 active cases and has become the most influential state-court paraquat docket in the country.

The first paraquat bellwether case in the Philadelphia program settled confidentially on the courthouse steps in January 2026, minutes before jury selection began. The dollar figure is sealed. Defendants do not settle bellwether cases on the courthouse steps when they like their odds.

In April 2025 Syngenta publicly announced a settlement framework covering a substantial portion of pending federal paraquat claims. The framework operates through a qualified settlement fund with points-based allocation. It does not extinguish liability for cases that opt out and does not bind Chevron.

Yes — in March 2026, Syngenta announced it would discontinue U.S. production of paraquat. Existing stocks continue to be sold and applied. The discontinuation does not extinguish liability for past exposures.

Nothing upfront. Reputable paraquat firms work on contingency — typically one-third of any recovery — and only get paid if you win. The case review itself is always free and confidential.

Typically 12 to 36 months from filing to disbursement for cases that settle, longer for cases that go to trial. Pennsylvania state court generally moves faster than federal MDL.

It varies by state and by accrual rule. Pennsylvania applies a two-year limitations period for personal injury actions, subject to the discovery rule. The clock starts when the cause of action accrued — usually when diagnosis is made and the link to paraquat exposure becomes reasonably knowable.

Surviving family members may have wrongful death and survival claims. These have their own — often shorter — statutes of limitations. Call promptly.

Documented exposure (employer records, applicator license records, supplier records, photographs, witness statements) and a Parkinson's diagnosis from a qualified neurologist. Your legal team can reconstruct exposure history even when your memory is fuzzy on brand names or dates.

Yes. Brand recall is helpful but not required. Employer records, supplier invoices, and applicator records can reconstruct what you handled.

No. The U.S. EPA permits paraquat under Restricted Use rules. More than 60 countries — including the EU, China, Brazil, and Switzerland (Syngenta's home country) — have banned paraquat. The U.S. has not.

Paraquat (paraquat dichloride) and Roundup (glyphosate) are different herbicides, made by different companies, with different mechanisms and different injury profiles. Roundup is associated with non-Hodgkin lymphoma; paraquat is associated with Parkinson's disease. The two litigations are unrelated though sometimes confused.

Yes — particularly if you have suggestive symptoms (resting tremor, slowness of movement, muscle rigidity, micrographia, loss of smell, REM sleep behavior disorder). Even without a confirmed diagnosis the case review is worth doing.

Most cases settle without trial. If your case does go to trial, your attorney will prepare you thoroughly. Most of the litigation work happens through documents, depositions, and negotiation — not courtroom appearances.

Filed lawsuits are public record, but settlements are typically confidential. Your case review and intake conversation are always confidential.

Three structural reasons: faster pace through the Philadelphia Complex Litigation Center, juries with a documented history of higher verdicts in toxic tort cases, and broader jurisdiction under Pennsylvania's consent-by-registration statute. Defendants pay more to resolve Philadelphia cases because their downside risk at trial is higher.

Most paraquat plaintiffs were exposed 20 to 40 years before diagnosis. Long latency is the expected pattern, not a defense. The discovery rule generally applies to long-latency Parkinson's claims.

Residential drift exposure can support a claim with additional documentation — proximity to treated fields, application records, and a clean differential diagnosis. Drift cases are harder than occupational cases but not impossible.

Movement disorder specialist diagnosis is preferred for case value and for clean differential diagnosis. A general neurologist diagnosis is acceptable; we can help arrange a confirmatory referral if needed.

Essential tremor is a different diagnosis and does not currently support a paraquat claim. Distinguishing essential tremor from Parkinson's is one of the reasons movement disorder specialist evaluation matters.

Spousal loss of consortium claims are available in some states. Wrongful death and survival claims are available when the exposed person has died from Parkinson's-related complications.

Successor liability and exposure documentation through other sources (applicator license records, supplier records, OSHA records) can fill the gap. Don't let a defunct former employer stop you from calling.

Workers' compensation is a parallel system. Liens from comp carriers can attach to your recovery, but a skilled lien resolution team can negotiate these down. Comp benefits do not bar a product liability claim against Syngenta or Chevron.

Medicare and Medicaid both have lien rights against personal injury recoveries that paid for related medical care. A Medicare set-aside may be required to fund future Parkinson's care. Your attorney's lien resolution team handles this.

Eligibility analysis is fact-specific. For most claimants with strong facts, Pennsylvania state court offers higher expected recovery, faster pace, and broader procedural protections. For some claimants, the federal settlement framework offers faster certainty. Discuss the trade-off with your lawyer.
