Vermont becomes first US state to ban paraquat herbicide over Parkinson’s fears
Vermont banned paraquat, citing research tying the herbicide to Parkinson’s disease. The law starts Nov. 1 and includes limited permits for some crops through 2030.
Intelligence analysis by GPT-5.4 Mini
Vermont has become the first US state to ban paraquat, a widely used herbicide linked by lawmakers to Parkinson’s risk. The law still allows limited permits for certain fruit crops and adds reporting and study requirements.
Vermont decided to stop using a weedkiller called paraquat because some studies say it may raise the chance of getting Parkinson’s disease, a serious brain illness. Think of it like a warning sign on a tool that might hurt people more than it helps.
The state did not make the rule all at once for every use. Some farmers can still get special permission for certain crops for a few years while they look for other options.
The bigger fight is about safety versus farming needs. Some people say the weedkiller helps crops; others say the possible harm is too serious to ignore.
Analysis
What Vermont did
Governor Phil Scott signed legislation making Vermont the first US state to ban paraquat herbicide. The ban takes effect on 1 November, but the law leaves room for regulators to issue special permits for use on fruit-producing tree orchards, berries, and other small fruit crops until 31 December 2030.
Why lawmakers backed it
Supporters pointed to studies, including ones cited from the National Institutes of Health, that they say link paraquat exposure with a substantially higher risk of Parkinson’s disease. The bill also references research connecting paraquat with non-Hodgkin lymphoma and childhood leukemia. Lawmakers who supported the ban argued that the health risk outweighed the cost to farmers.
The political and agricultural trade-off
Some legislators worried that Vermont growers would be at a disadvantage if paraquat remains legal in other states. To address that concern, the law requires annual reporting on paraquat use in Vermont and a state-funded study on alternatives for farmers.
Wider context
Paraquat has been used in the US since 1964 and is one of the country’s most widely used herbicides, despite bans in several other countries. Syngenta, a key maker of the chemical, has denied credible evidence linking paraquat to Parkinson’s, but it has also faced thousands of US lawsuits over those allegations. The company said in April it would stop making paraquat and would no longer try to sell paraquat products in the US and other countries, though generic versions remain available. The move in Vermont adds momentum to similar efforts in other states and at the federal level.
Key points
- Vermont is the first US state to ban paraquat herbicide.
- The ban starts on 1 November, with limited permits allowed for some fruit crops until 2030.
- Lawmakers cited studies they say link paraquat exposure to Parkinson’s disease and other illnesses.
- The law also requires annual reporting and a state-funded study of alternatives for farmers.
- The move adds pressure for wider state and federal restrictions on paraquat.
