Vermont Applauded for Banning Parkinson's-Linked Neurotoxic Herbicide Paraquat
Noting that "70+ countries and one US state" have banned the chemical, the Michael J. Fox Foundation said that "this is a clear and critical message" to federal and state lawmakers that "the time to ban paraquat is now."
May 26, 2026
In a move cheered by advocates for public health and the environment, Vermont on Tuesday became the first US state to ban paraquat, a neurotoxic herbicide banned in over 70 countries but protected by the Trump administration despite being linked to Parkinson's disease.
Democratic Vermont Gov. Phil Scott signed H. 739, which bans the sale and use of paraquat, after the legislation was passed by the state Legislature with strong bipartisan support. The ban—which contains a provision allowing for limited use of the chemical on fruit orchards through the end of 2030—is set to take effect on November 1.
As Public Interest Research Group (PIRG) campaigner Liam Sacino recently noted, the US Environmental Protection Agency [EPA] acknowledges that "even a small amount" of paraquat "can be fatal, and there is no known antidote."
"The agency has also decided that due to health risks, it should never be used around home gardens, schools, recreational parks, golf courses, or playgrounds," Sacino added. "Regardless of these conclusions, the EPA still allows paraquat to be sprayed on farms, posing a potentially increased risk to those who work on the farms and live nearby."
The EPA paradoxically calls paraquat "an important tool for the control of weeds in many agricultural and non-agricultural settings," a stance promoted by the chemical industry, some of whose highly toxic products the pesticide-friendly Trump administration has designated as vital to US national security.
Ban advocates point to mounting evidence that paraquat exposure greatly increases the risk of developing Parkinson's disease, a neurodegenerative illness. One recent UCLA study found that the odds of developing Parkinson's could more than double for people living within 500 meters of paraquat application.
That study added to a body of research linking paraquat to Parkinson's that dates back to at least 2011, when National Institutes of Health researchers concluded that the brain disorder is “positively associated” with the herbicide. A 2013 paper published in the peer-reviewed journal Neurology found that exposure to paraquat roughly doubled the risk of developing Parkinson’s. In 2020, four of the world’s leading neurologists published a book citing paraquat as a cause of the ailment.
Parkinson's advocacy groups, including the Parkinson's Foundation and Michael J. Fox Foundation, hailed the Vermont ban.
The Michael J. Fox Foundation noted that "70+ countries and one US state have now banned paraquat."
"This is a clear and critical message to other states and our federal government: The time to ban paraquat is now," the group added.
Environmental groups also cheered the ban.
"We applaud Gov. Scott and the champions in the Legislature that made this moment possible that will protect all Vermonters, including farmers and children, from being exposed to this dangerous chemical,” Environmental Working Group legislative director Geoff Horsfield said in a statement.
“With Vermont leading the way, states across the country now have a clear path to end the use of one of the most toxic herbicides still on the market,” Horsfield added. “This is a turning point in the effort to protect public health from a chemical that has been tied to devastating neurological harm.”
Other states including California, New Jersey, New York, and Pennsylvania have either introduced bills to ban or strictly limit paraquat, or are considering doing so.
"We should not wait for federal action when we can act now to protect farmworkers and families," PIRG's Sacino said Tuesday.

The Truth About Roundup Herbicide
For decades Roundup has been sold as an effective herbicide, one that was safe for humans and the environment. It isn't.
Mar 01, 2026
Mark Twain supposedly once said, "Never let the truth get in the way of a good story," but there is a difference between a good story told in fun and a story (supposedly backed by independent scientific research) that people are led to believe because, well, science is supposed to be true. And so we come to the story of Roundup, the herbicide developed by Monsanto that swept the world because it worked and was the “safe” alternative to widely used weedkillers like Dicamba and 2,4-D,—it was said to be safer than table salt!
Roundup was developed in the 1970s as a non-selective herbicide, meaning it would kill almost any growing plant it touched. It was an effective burn-down herbicide farmers could apply prior to planting, and it assured an almost weed-free field at the beginning of the growing season. Roundup could be used in non-agricultural situations as well, to kill weeds and grass growing in sidewalk and patio cracks, around buildings, etc, but care was needed because, as noted, it was non-target and could kill whatever plant it touched.
For farmers, it worked well, except while it did kill growing weeds, buried weed seeds were not harmed, so a weed-free field at planting time did not ensure a weed-free field throughout the growing season. Weeds would continue to sprout, and more herbicide applications would be needed during the growing season.
Then Monsanto developed their big fix released in 1996, genetically engineered (GE) soybeans resistant to Roundup, followed by GE versions of other commodity crops: corn, cotton, sugar beet, and canola. Over-the-top spraying of these GE crops would kill everything but the crop, and Roundup became one of the most widely used herbicides in the world and GE crops came to dominate world commodity crop production.
Companies like Bayer have to protect their product and their profit even if they have to tell a few lies to do so.
While Monsanto sold Roundup with the slogan, “One spray is all you’ll ever need,” in time, it became clear that some weeds were developing resistance to Roundup and farmers were right back where they started, looking for herbicides that worked consistently. More genetic modifications were made to commodity crops making them resistant to other herbicides, like Dicamba and 2,4-D, the herbicides Roundup was supposed to have replaced. These multiple GE or “stacked” crops could be sprayed with a cocktail of herbicides, hopefully ensuring weed-free fields for the entire growing season.
Farmers are using more herbicide, even on the GE crops, and costs for GE seed have risen much faster than non-GE seed. Of course, the motive was never to reduce the farmer’s production costs or agricultural herbicide use but to increase it—that's where the profit is.
For farmers who didn’t jump on the GE bandwagon, finding non-GE seed is often difficult. Even more onerous, some farmers have found it necessary to plant GE seed as a preventative measure because non-GE crops can be damaged by chemical drift from neighboring GE fields.
So much for effectiveness, what about the safety of Roundup? In 2000 a study was published in the journal Regulatory Toxicology and Pharmacology that deemed the active ingredient in Roundup (glyphosate) was safe and not a human health risk. Since then, that study has been cited consistently as proof of Roundup’s safety. Numerous other studies have shown that glyphosate could cause cancer and that the inert ingredients that are part of the patented Roundup formulation increase the toxicity of glyphosate. Further, the practice of using Roundup as a desiccant on small grain crops (oats, wheat, and barley) prior to harvest puts Roundup directly on grain that enters the human food chain.
Since acquiring Monsanto in 2018, Bayer has paid out about $11 billion to settle almost 100,000 cancer-related lawsuits with approximately 61,000 still pending. In December of 2025 another blow to the claimed safety of Roundup came when the Regulatory Toxicology and Pharmacology journal withdrew the 2000 article that had touted Roundup’s safety. While the study claimed to be independent and peer reviewed, it has come to light that Monsanto's scientists played a significant role in conceiving and writing the article. Oops.
For decades Roundup has been sold as an effective herbicide, one that was safe for humans and the environment, and without which “consequences would be dire.” Companies like Bayer have to protect their product and their profit even if they have to tell a few lies to do so. They claim to produce safe products that help farmers thrive—real independent research refutes that. Bayer and the agribusiness industry may be thriving, but farmers are not and in these times, too few people seem to care that lies are accepted as truth.

'Life-Threatening Catastrophe': Trump Gutting of USAID Halts Agent Orange Cleanup Work
"The damage this administration has already done throughout the world is pretty staggering."
Mar 17, 2025
The Trump administration's unlawful dismantling of the U.S. Agency for International Development has ground to a halt critical Agent Orange cleanup efforts in Vietnam, which American forces sprayed extensively with the toxic, cancer-linked chemical between 1961 and 1971—impacting an estimated 3 million people.
ProPublica reported Monday that "workers were in the middle of cleaning up the site of an enormous chemical spill, the Bien Hoa air base, when Secretary of State Marco Rubio abruptly halted all foreign aid funding" last month.
"The shutdown left exposed open pits of soil contaminated with dioxin, the deadly byproduct of Agent Orange," the investigative outlet noted. "After Rubio's orders to stop work, the cleanup crews were forced to abandon the site, and, for weeks, all that was covering the contaminated dirt were tarps, which at one point blew off in the wind."
"And even more pressing, the officials warned in a February 14 letter obtained by ProPublica, Vietnam is on the verge of its rainy season, when torrential downpours are common. With enough rain, they said, soil contaminated with dioxin could flood into nearby communities, poisoning their food supplies," the outlet continued, observing that hundreds of thousands of people live around the air base.
Officials who sounded the alarm didn't receive a response from the Trump administration, according to ProPublica. The officials in Vietnam warned their colleagues in Washington that "we are quickly heading toward an environmental and life-threatening catastrophe."
The Vietnamese Red Cross estimates that more than 150,000 children in the country have been born with ailments attributable to Agent Orange.
Last month, as U.S. President Donald Trump and billionaire Elon Musk took aim at USAID, The New York Times spotlighted the story of Nguyen Thi Ngoc Diem, who the newspaper noted was "born with a malformed spine and misshapen limbs—most likely because her father was exposed to Agent Orange."
"It makes no sense," Diem told the Times in response to the Trump administration's assault on USAID. "Agent Orange came from the U.S.—it was used here, and that makes us victims. A little support for people like us means a lot, but at the same time, it's the U.S.'s responsibility."
In the wake of Trump's illegal funding freeze at USAID, the Times noted that "bulldozers that were cleaning up contamination at a former American air base in southern Vietnam—which both countries might eventually want to use—have gone silent."
"Around 1,000 mine-removal workers in central Vietnam have been sent home," according to the Times. "Even if funding returns, in a year meant to mark recovery from the darkness of a cruel war, fundamental damage has already been done in ways that feel—for partners and victims in both countries—like a knife shoved into old wounds."
ProPublica stressed Monday that the Trump administration has not just ordered cleanup work to stop. It has also "frozen more than $1 million in payments for work already completed by the contractors the U.S. hired."
Jan Haemers, the CEO of Haemers Technologies—a company that has worked on Agent Orange cleanup in Vietnam—told ProPublica that "halting a project like that in the middle of the work" amounts to "an environmental crime."
"If you stop in the middle," Haemers said, "it's worse than if you never started."
