Do you suffer from Parkinson’s disease or related symptoms after possible exposure to the weed killer known as paraquat? You may be entitled to compensation.


Paraquat dichloride (“paraquat”) is a commercial herbicide so toxic that the EPA has had to issue warnings to users that “one sip can kill.” Unlike RoundUp, paraquat is not a residential product that anybody can purchase from their local home and garden store. It is only sold to commercial growers. Users must receive EPA-approved training every three years to mix, load, apply, and handle paraquat.

Several studies have shown that exposure to paraquat significantly increases the risk of Parkinson’s. Farm workers and nearby residents can be exposed to paraquat through the air. Paraquat can also be transferred onto clothing, finding its way into peoples’ homes. This puts entire communities in farm country at risk.

Paraquat is found in lots of commercial weed killers, including:

  • Gramoxone
  • Cyclone
  • Cyclone Star
  • Firestorm
  • Helmquat
  • Parazone
  • Quick-Quat
  • Purgatory
  • Willowood Paraquat
  • Bonedry
  • Blanco
  • Devour
  • Para-Shot 3.0
  • Ortho Paraquat
  • And many others

Many countries, including those in the European Union, China, and Brazil are either phasing out its use or have banned it completely. Yet here in the United States, the use of paraquat in on the rise, and was reapproved by the EPA in October of 2020 for continued use.
