The ban on Paraquat in United States — Vermont, the first US state to do so, is expected to have a limited direct impact on the overall agricultural chemicals market due to the state's small usage. However, it sets a significant precedent that could lead to similar bans in other states, potentially impacting major manufacturers like Syngenta and increasing demand for alternative herbicides. Farmers in United States — Vermont, particularly apple and berry growers, may face increased costs and competitive disadvantages compared to those in states where Paraquat remains legal, affecting their profitability.

United States — Vermont has become the first US state to ban the herbicide Paraquat, effective November 1, with exemptions for fruit growers until 2030. This decision, driven by concerns over a potential link between Paraquat and Parkinson s disease, was widely supported by public health advocates like The Michael J. Fox Foundation and State Representative Esme Cole, who sponsored the bill. While the Guyana — Guyana Environmental Protection Agency has not found a clear link, research from the United States — National Institutes of Health suggests a strong association. Syngenta, a major manufacturer, has ceased global production and sales of Paraquat and faces thousands of lawsuits, though it maintains the chemical's safety. Farmers like Greg Burtt, who rely on Paraquat as a cost-effective tool, express concerns about competitive disadvantages and increased labor costs with alternative methods. The ban is seen as a significant step by the Parkinson's community, with calls for other states and the federal government to follow United States — Vermont's lead.
