Why are people suing paraquat manufacturers?

Paraquat dichloride, or “paraquat,” is a chemical compound that has been commonly used as an herbicide since the 1960s. This substance is highly toxic, and consuming even one tablespoon by mistake could be fatal. Paraquat has been classified as a Restricted Use Product by the Environmental Protection Agency (EPA), and only licensed herbicide applicators can purchase it for commercial use.

In 2011, the National Institutes of Health published an academic study showing a link between paraquat exposure and Parkinson’s disease. This study would later inspire the first product injury lawsuit against big-name paraquat manufacturers like Syngenta and Chevron in 2017, and thousands more claims would follow close behind.

How to qualify for the paraquat lawsuit

To qualify for the Paraquat lawsuit and receive a settlement, you’ll need to prove two things: that you previously used an herbicide product with paraquat as the main ingredient, and that you were diagnosed with Parkinson’s disease. Claim eligibility expires 20 years after your initial diagnosis.


Any brand of herbicide with paraquat as the primary ingredient will qualify, but we’ve included a few of the more common brands and companies being sued in the lawsuit:

  • Gramoxone, made by Syngenta & distributed by Chevron, Inc.

  • Firestorm, made by Chemtura Corporation

  • Parazone 3SL, made by AMVAC Group Company
  • Quick-Quat, made by Drexel Chemical Company
  • Para-SHOT 3.0, made by Sharda USA
  • Helmquat 3SL, made by Helm Agro US, Inc.

Frequently asked questions about the paraquat lawsuit

If you have anything else you want to ask, reach out to us.

Are any other illnesses able to qualify for the paraquat lawsuit?

Yes! Though the primary illness involved in the paraquat lawsuit is Parkinson’s disease, people who have developed either Progressive supranuclear palsy (PSP) or Multiple system atrophy (MSA) after paraquat exposure may also be able to qualify for the lawsuit.

Is paraquat used in Roundup, and are the lawsuits related?

No, paraquat is not used in any Roundup weed killer products, and the two lawsuits have no relation to each other.


Though paraquat and Roundup are both herbicides, they are made with different active ingredients that have been linked to unique health effects. Roundup is made with an herbicide called glyphosate, which has been linked to an increased risk of developing blood cancers like Non-Hodgkin’s Lymphoma.

How much can I expect to win from a paraquat settlement?

Since this is a relatively new lawsuit that has not yet made it to trial due to delays, legal proceedings have not reached any settlements or verdicts as of 2024.

We’ll keep you updated on any future developments about this lawsuit and the average payouts that claimants receive once trials have begun.
