'This Is the PFAS Presidency': Trump EPA Approves Another Forever Chemical Pesticide
"The Trump administration's EPA is once again showing its disdain for Americans' health and the natural world."
Jul 01, 2026
Environmental and public health advocates on Wednesday ripped the US Environmental Protection Agency's fifth approval of a "forever chemical" pesticide during the current term of President Donald Trump, who campaigned on a promise to "Make America Healthy Again."
Despite that pledge, Trump's second administration—much like his first—has served the pesticide industry in various ways, including by putting out a MAHA report that echoes industry talking points, installing a former industry lobbyist in a key EPA post, backing Bayer-owned Monsanto over cancer patients at the US Supreme Court, and issuing an executive order that mandates the production of glyphosate.
Under Trump, the EPA has also approved or reapproved various controversial pesticides, from atrazine and dicamba to trifludimoxazin, which was approved late Tuesday. Like diflufenican and epyrifenacil, which were authorized by the EPA earlier Tuesday, as well as cyclobutrifluram and isocycloseram, which got a green light from the agency last November, trifludimoxazin is what some scientists and campaigners call a forever chemical pesticide.
Per- and polyfluoroalkyl substances (PFAS)—which have been used in not only pesticides but also fabrics, firefighting foam, nonstick cookware, and other household products—are widely known as forever chemicals because they don't break down naturally. They're also linked to a range of health issues, including various cancers.
"This is the PFAS presidency brought to you by Donald Trump and EPA Administrator Lee Zeldin," Nathan Donley, environmental health science director at the Center for Biological Diversity, declared Wednesday.
As with his Tuesday critique of the Trump EPA approving diflufenican and epyrifenacil, Donley pointed to the Supreme Court's recent ruling in favor of Trump-backed Bayer, rather than the thousands of Americans who argue that Monsanto's glyphosate-based weedkiller Roundup caused their cancer.
"Waiting to open the floodgates on new pesticide approvals until after the Supreme Court granted immunity to pesticide companies takes a special kind of callousness," he said.
Bill Freese, science director at Center for Food Safety (CFS), similarly said Wednesday that "with yesterday's pesticide approvals, the Trump administration's EPA is once again showing its disdain for Americans' health and the natural world."
"The EPA's pesticide division is seemingly no longer able to recognize evidence that a pesticide causes cancer, even when it's the pesticide company's own studies that show it," he continued. "And as per usual, EPA dismisses out of hand incriminating independent studies by scientists not affiliated with the pesticide industry."
In addition to the PFAS pesticides, the EPA is under fire this week for approving new uses for chlormequat, a non-PFAS pesticide tied to reproductive issues, and the fungicide fluoxapiprolin.
CFS co-executive director Sylvia Wu pointed out that the agency dismissed studies showing that fluoxapiprolin and epyrifenacil both produce tumors in laboratory rodents and classified both as "not likely to be carcinogenic to humans."
"The EPA's illegitimate rejection of the evidence that these two pesticides cause cancer is very similar to the tricks it pulled in denying glyphosate could cause cancer," Wu said. "These blatant violations of the agency's own cancer guidelines are unacceptable."
As for chlormequat, Freese said that "EPA should never have approved this endocrine-disrupting pesticide, particularly since its persistence and potential for widespread use on wheat and other widely consumed grains will mean universal exposure."
Already, "chlormequat is found in the urine of 90% of Americans, thought to come mostly from residues on imported foods where the pesticide has been used," the Center for Biological Diversity noted Wednesday. Like Freese, the group warned that "approval of its use on US wheat and oats ensures that exposure to the US population will increase dramatically."

EPA Ripped for 'Routinely' Failing to Label Cancer-Causing Pesticides
"If the agency is going to allow such chemicals to be freely sold at Home Depot, Walmart, and farm supply stores, the very least the EPA must do is require a clear cancer warning on the label," said one critic.
Mar 30, 2026
The US Environmental Protection Agency has repeatedly failed to warn consumers of the cancer risks posed by pesticides—even when its own research has found those products to be carcinogenic, a pair of green groups said Monday.
The Center for Food Safety studied the EPA's permitted risk level in active components of both currently approved and legacy pesticides. CFS researchers found that the EPA allowed pesticides with a cancer risk "as high as 1 in every 100 people exposed, a far greater level than the EPA’s benchmark of a 1-in-a-million chance of developing cancer."
"Of the 570 unique pesticide chemicals that EPA’s Office of Pesticide program has classified for carcinogenic potential since 1985, over one-third (200, or 35%) are either possible human carcinogens (127) or likely to be carcinogenic to humans (73)," the CFS report notes. "The status of 62 others (11%) is uncertain, because EPA lacks sufficient data to make a determination.
A second report, from the Center for Biological Diversity (CBD), shows that of the 200 pesticides that are possible or likely human carcinogens, 125 are still registered for use.
CBD analyzed the labels of every pesticide currently approved by the EPA and found that the agency has placed cancer warnings on just 69 of 4,919 pesticide labels (1.4%) "containing an active ingredient that the agency has designated a 'likely' human carcinogen." Additionally, the EPA has put cancer warnings on just 242 of the 22,147 pesticide labels (1.1%) that "contain an ingredient the agency has designated as a 'possible' human carcinogen."
CFS science director Bill Freeses said in a statement Monday: “It’s bad enough that the EPA approves cancer-causing pesticides. But if the agency is going to allow such chemicals to be freely sold at Home Depot, Walmart, and farm supply stores, the very least the EPA must do is require a clear cancer warning on the label. Warnings save lives by incentivizing users to wear protective equipment that reduces risk."
Lori Ann Burd, director of environmental health at the CBD, said on Monday that “it's dumbfounding that the EPA has failed to require any cancer warning on thousands of pesticide products sold to the public that the agency itself has linked to cancer."
“Why should anyone have confidence in the EPA’s ability to keep tabs on the pesticide industry and protect us all from harmful poisons when it won’t even compel companies to put long-term health warnings on pesticides it knows are really dangerous?" she added.
Last month, CFS, CBD, and others denounced the EPA's reapproval of the pesticide dicamba—which scientific studies have linked to increased risk of cancer and hypothyroidism in high-dose exposure—for certain cotton and soybean crops.
The new CFS and CBD analyses come ahead of next month's oral arguments in Monsanto Company v. John L. Durnell, a case before the US Supreme Court in which Bayer, the Germany-based pharma giant that bought Monsanto in 2018, is seeking substantial immunity from future lawsuits filed by people in the United States who used glyphosate-based products like Roundup weedkiller and were then diagnosed with rare pesticide-linked cancers. The company has paid out billions of dollars to settle such suits.
CBD and other advocacy groups have also warned that the industry-backed Farm Bill currently advancing in the Republican-controlled Congress weakens or delays pesticide safety regulation, preempts state-level cancer warning rules, and shields chemical companies from lawsuits.

'Industry Cronies' at Trump's EPA Reapprove Dangerous Pesticide Dicamba
"It’s hard to see how Making America Healthy Again was anything but another broken campaign promise," said one critic.
Feb 06, 2026
The US Environmental Protection Agency on Friday announced its anticipated reapproval of dicamba for two key crops, a move which, given the pesticide's proven health risks, places the EPA at apparent odds with President Donald Trump's vow to "Make America Healthy Again."
“The industry cronies at the EPA just approved a pesticide that drifts away from application sites for miles and poisons everything it touches,” Nathan Donley, environmental health science director at the Center for Biological Diversity, said in response to Friday's announcement.
“With the EPA taking aggressive pro-pesticide industry actions like this, it’s hard to see how Making America Healthy Again was anything but another broken campaign promise," Donley added. "When push comes to shove, this administration is willing to bend over backward to appease the pesticide industry, regardless of the consequences to public health or the environment.”
The EPA said in a statement that the agency "established the strongest protections in agency history for over-the-top (OTT) dicamba application on dicamba-tolerant cotton and soybean crops," and that "this decision responds directly to the strong advocacy of America's cotton and soybean farmers."
While scientific studies have linked exposure to high levels of dicamba to increased risk of cancer and hypothyroidism and the European Union has classified dicamba as a category II suspected endocrine disruptor, the EPA said Friday that "when applied according to the new label instructions," it "found no unreasonable risk to human health and the environment from OTT dicamba use."
This is the third time the EPA has approved dicamba for OTT use. On both prior occasions, federal courts blocked the approvals, citing underestimation of the risk of chemical drift that could harm neighboring farms.
The agency highlighted new restrictions on dicamba use it said will reduce risk of drift.
"EPA recognizes that previous drift issues created legitimate concerns, and designed these new label restrictions to directly address them, including cutting the amount of dicamba that can be used annually in half, doubling required safety agents, requiring conservation practices to protect endangered species, and restricting applications during high temperatures when exposure and volatility risks increase," it said.
Critics noted that the EPA during the Biden administration published a report revealing that during Trump’s first term, senior administration officials intentionally excluded scientific evidence of dicamba-related hazards, including the risk of widespread drift damage, prior to a previous reapproval.
Others pointed to the recent appointment of former American Soybean Associate lobbyist and dicamba advocate Kyle Kunkler as the EPA's pesticides chief.
"Kunkler works under two former lobbyists for the American Chemistry Council, Nancy Beck and Lynn Dekleva, who are now overseen by a fourth industry lobbyist, Doug Troutman, who was recently confirmed to lead the chemicals office following endorsement by the chemical council," the Center for Food Safety (CFS) noted Friday.
The Trump EPA has also come under fire for promoting the alleged safety of atrazine, a herbicide that the World Health Organization says probably causes cancer, and for pushing the US Supreme Court to shield Bayer, which makes the likely carcinogenic weedkiller Roundup, from thousands of lawsuits.
CFS science director Bill Freese said that “the Trump administration’s hostility to farmers and rural America knows no bounds."
“Dicamba drift damage threatens farmers’ livelihoods and tears apart rural communities," Freese added. "And these are farmers and communities already reeling from Trump’s [Immigration and Customs Enforcement] raids on farmworkers, the trade war shutdown of soybean exports to China, and Trump’s bailout of Argentina, whose farmers are selling soybeans to the Chinese—soybeans China used to buy from American growers.”
