Paraquat is one of the most acutely toxic herbicides ever used in commercial agriculture. Banned in more than 30 countries — including the European Union, China, and Brazil — it remains in widespread use across the United States, where the EPA classifies it as a Restricted Use Pesticide. A growing body of scientific evidence links paraquat exposure to Parkinson's disease, and Syngenta is now facing thousands of consolidated lawsuits in federal court. Farmers, agricultural workers, and rural residents who developed Parkinson's after exposure may be entitled to compensation.
Decades of peer-reviewed research, unsealed corporate documents, and a growing federal multidistrict litigation have brought Syngenta's most controversial product into court.
Multiple peer-reviewed studies — including research funded by the National Institutes of Health — have documented a significantly elevated risk of Parkinson's disease in people exposed to paraquat, particularly those exposed over years and at higher concentrations. Paraquat is toxic to dopamine-producing brain cells, the same neurons destroyed in Parkinson's.
Internal documents unsealed in litigation suggest Syngenta, the herbicide's primary manufacturer, was aware of paraquat's neurological risks for decades while continuing to market it to American farmers. Plaintiffs allege the company failed to warn users, downplayed safety risks, and worked to delay regulatory action.
Thousands of paraquat lawsuits have been consolidated into a multidistrict litigation in the Southern District of Illinois. Bellwether trials and global settlement negotiations are advancing, and plaintiffs continue to file new cases as more people learn of the link between their work history and their diagnosis.
Licensed pesticide applicators, agricultural workers, farmers, and people who lived or attended school near sprayed fields face the highest exposure risk. Even people who never mixed or applied paraquat directly — but lived near treated land — have developed Parkinson's at elevated rates.

We work with attorneys who have litigated paraquat and other agricultural exposure cases — lawyers who understand the science, the regulatory record, and Syngenta's defenses.
Parkinson's progresses over years. Our intake team takes the time to understand your full exposure history, diagnosis, and how the disease has affected your life and family.
Paraquat cases are handled on contingency. You pay no upfront costs, no hourly fees, and no attorney fees unless your case results in a settlement or verdict.
Settlements help cover the long-term cost of Parkinson's care — medication, therapy, in-home support — and hold an industry accountable for what it knew. We're focused on real results.
It takes less than two minutes. There's no obligation. If your case qualifies, we'll connect you directly with an attorney handling paraquat claims.
