Paraquat Parkinson's Lawsuit in Texas

What Texas residents should know

Texas residents are not necessarily limited to filing only in Texas state court. Many mass tort claims may be evaluated by national firms, filed in federal court, coordinated through MDL proceedings, or handled through another legal process.

State law may still matter for deadlines, damages, claim evaluation, and certain procedural issues.

What stands out about Paraquat litigation in Texas?

Texas matters for paraquat litigation primarily because of cotton. Per the USDA NASS 2021 Cotton Chemical Use survey, Texas accounted for roughly 56.7% of U.S. cotton planted acreage (about 6.37 million acres), and paraquat was applied to about 27% of surveyed U.S. cotton acres (~1.7 million pounds applied) as a pre-plant burndown and harvest-aid desiccant. That makes Texas one of the largest documented paraquat-use environments in the country.

Federal paraquat cases filed by Texas residents in any of the four Texas federal districts are transferred by the JPML into MDL-3004 (S.D. Illinois, Chief Judge Nancy J. Rosenstengel) for coordinated pretrial proceedings. Texas administers the federal restricted-use pesticide program rather than maintaining a state RUP list.

As of mid-2026, a review of Texas Attorney General announcements did not surface a state-level paraquat action against Syngenta or Chevron; this is an absence-of-evidence statement rather than a guarantee. Texas's product-liability statute of limitations is generally two years (Tex. Civ. Prac. & Rem. Code § 16.003), and Texas applies a 15-year statute of repose to many product-liability claims (§ 16.012).

Possible eligibility factors

Texas residents may want to speak with a lawyer if they used or were exposed to Paraquat herbicide products and later experienced Parkinson's disease.

• Neurology records, movement-disorder specialist notes, medication history, and Parkinson's diagnosis records.
• Co-worker names, witness statements, photos, calendars, safety training, and documents tying exposure to a product and season.

What is the filing deadline for Paraquat lawsuits in Texas?

For a Texas resident researching Paraquat claims, the starting point is usually Texas's general personal injury period: 2 years under Tex. Civ. Prac. & Rem. Code § 16.003. That is only a starting point, not a final legal deadline for every person.

The real filing deadline can depend on diagnosis date, when the injury and possible cause were discovered, exposure location, wrongful-death issues, prior claim paperwork, and whether the case is filed directly, transferred to an MDL, or handled through another process.

Discovery-rule note: Texas recognizes a discovery rule in limited circumstances involving inherently undiscoverable injuries.

How long do Texas residents have to file?

Texas's personal injury statute of limitations applicable to product liability claims is 2 years (Tex. Civ. Prac. & Rem. Code § 16.003). Accrual timing, tolling, and repose periods can still change the real deadline in an individual case.

• Filing period: 2 years — Tex. Civ. Prac. & Rem. Code § 16.003.
• Discovery rule: Texas recognizes a discovery rule in limited circumstances involving inherently undiscoverable injuries.
• Statute of repose: Texas applies a 15-year statute of repose to many product liability claims (§ 16.012).

Because the controlling deadline depends on diagnosis date, discovery facts, exposure history, wrongful-death rules, and how the claim is filed, only a licensed attorney can confirm the deadline that applies to a specific situation. This page is general legal information, not legal advice.

What should Texas residents ask a lawyer?

• What proof do you need to connect my farm, applicator, or bystander exposure specifically to paraquat?
• How do Parkinson's diagnosis date, symptom history, and neurology records affect review?
• Does the confidential settlement program affect whether my claim can be evaluated?
• How do state filing deadlines affect my exposure and diagnosis timeline?
• Would my claim be handled locally, nationally, or through the MDL?
• Are there upfront costs?
