Paraquat Lawsuits


Paraquat, also known as Gramoxone, is a popular herbicide used in the United States for weed killing that has been linked to many side effects, including Parkinson’s disease. Due to its high toxicity, Paraquat is restricted to commercial use only by licensed applicators. Farmers, agricultural laborers, and those who live near industrial or commercial farms are at risk of Paraquat exposure. If you or a loved one have been diagnosed with Parkinson’s disease due to Paraquat exposure, you may be eligible for financial compensation, including the cost of medical bills, treatments, loss of income, and other out of pocket expenses incurred in your recovery. Our product liability attorneys are available to speak with you today, and we offer free consultations. 

Nationwide, lawsuits are being filed against Syngenta and Chevron Phillips Chemical Co. for their role in manufacturing and selling Paraquat throughout the United States. 

Spraying Plants with Herbicide


Paraquat was first produced for commercial purposes over 60 years ago by Imperial Chemical Industries. Paraquat is popular amongst farmers in the United States due to being quick-acting and non-selective in killing green plant tissue. Paraquat is also effective in killings weeds that have developed resistance to glyphosate, which is the active ingredient in Roundup. Exposure to Paraquat has been linked to the development of Parkinson’s disease. Due to its high toxicity, the EPA has banned the use of Paraquat for residential use in the United States and Paraquat is banned entirely in more than 32 countries. In light of these concerns and in accordance with its 15-year evaluations, the EPA reapproved its restrictions against residential use of Paraquat in October 2020. According to the EPA, one sip of Paraquat is potentially enough to kill an individual.  

Sygenta is the major manufacturer of Paraquat under the trade name Gramoxone. In 2017, China National Chemical Corp. (“ChemChina”) bought Syngenta and Syngenta now manufacturers Paraquat as a ChemChina subsidiary. While the UK and China have banned use of Paraquat for its citizens, the herbicide is produced at Sygenta facilities throughout these countries and exported to the United States. 

Paraquat is sold under multiple names including: 

  • Gramoxone 
  • Blano
  • Bonfire Herbicide
  • Devour
  • Firestorm
  • Helmquat 3SL
  • Para-Shot 3.0
  • Parazone
  • Quik-Quat
  • Bonedry
  • Cyclose SL 2.0 

For decades, thousands of Americans in the forestry, lawn care, and agriculture industries have used Paraquat as part of their daily work routine. Between 2006 and 2016, the total amount of Paraquat usage in the United States doubled. This has led to an increased risk of Paraquat exposure not only for those working on farms, but also for those individuals who live near farms or spend significant time on farms. Those most at risk for developing Parkinson’s disease from Paraquat use include: 

  • Commercial farmers 
  • Commercial landscapers 
  • Agriculture workers
  • Pickers
  • Groundskeepers
  • Individuals who live nearby a commercial farm 


Parkinson’s disease is a progressive nervous system disorder that affects movement. Symptoms start gradually and often include tremors, stiffness, slowness of movement, rigid muscles, impaired posture or balance, loss of automatic movements, speech changes, or writing changes. Although it is classified as a movement disorder, Parkinson’s disease can cause non-movement symptoms as well including, but not limited to, cognitive impairment, depression, sleep disorders, and constipation. Parkinson’s affects nearly 1 million people in the United States. Parkinson’s is a degenerative disease and there is no known cure. 

Over the past few years, a growing body of scientific evidence has linked exposure to Paraquat to Parkinson’s disease. While this news has only been discovered recently by the consumers who use Paraquat, the manufacturers of Paraquat have allegedly known of the significant dangers associated with their product for many years. As detailed by investigative reporting performed by Greenpeace UK, hundreds of secret company documents have been revealed throughout the pending litigation that show Paraquat manufacturers worked to hide and conceal the dangers of Paraquat exposure since it was first introduced commercially in the 1960s.   

According to studies quoted by The Unified Parkinson’s Advocacy Council, people exposed to Paraquat during their teenage or young-adult years have an increased Parkinson’s disease risk between 200 and 600 percent. In the lawsuits filed against the manufacturers and wholesalers of Paraquat, epidemiologists have been cited as finding that individuals exposed to Paraquat on the job have a 2 to 5-fold or greater increase in the risk of developing Parkinson’s disease following exposure. An Agricultural Health Study, which was conducted in part by the National Institutes of Health and the National Institute for Occupational Safety and Health, looked at the health of United States farmers over several years also discovered that Paraquat use increased their risk of developing Parkinson’s disease.


Currently, there are more than 100 cases pending in the Paraquat multi-district litigation before Judge Nancy Rosenstengel in the Southern District of Illinois. These cases were consolidated in June 2021 and it is expected that there will be a large number of additional claims filed.  

In June 2021, a trial is set to take place in St. Clair County Circuit Court in Illinois where farmers have sued Paraquat manufacturers and distributors, including Syngenta and Chevron, alleging that exposure to Paraquat led to their development of Parkinson’s. At this trial, it is expected that the Plaintiffs’ lawyers will put on proof related to the manufacturers’ concealment of their knowledge of the dangers of Paraquat.  

If you or a loved one developed Parkinson’s, you understand the toll it can take – physically, emotionally, and financially. People who suffer from Parkinson’s disease caused by exposure to Paraquat can pursue legal action for their losses, including medical bills, treatment, lost wages, pain and suffering, and loss of enjoyment of life. If the victim passed away, a wrongful death claim can be pursued in court. In addition to recovering compensatory damages, victims may be entitled to punitive damages, which are a special class of damages designed to punish a defendant for egregious conduct, such as knowingly hiding risks of using a consumer product from prospective users. There are certain time limitation requirements associated with filing these claims and a claim can be barred forever if not timely filed. 

The success of a lawsuit brought by victims and their Paraquat lawyers can depend largely on expert witnesses. Syngenta and Chevron are denying all wrongdoing in these cases, but expert doctors and researchers have found links between Paraquat exposure and Parkinson’s disease. In your case, medical experts and qualified scientists can review medical records and studies to determine if a causal link between Paraquat and the diagnosis exists. Expert witnesses can also testify about the cost of future medical treatment needed or a victim’s loss of income. Our law firm has the experience and resources to consult with qualified experts in order to properly pursue your product liability case.
