The Trump administration is appealing a federal court ruling that ordered the U.S. Environmental Protection Agency (EPA) to ban chlorpyrifos, a widely used pesticide tied to brain damage and other health problems in children.

In August, the Ninth Circuit Court of Appeals ruled the EPA must ban the pesticide within 60 days based on strong scientific evidence that chlorpyrifos—which is applied on dozens of fruit, nut and vegetable crops—is unsafe for public health.

Wine makers in West Texas are reeling from herbicide drift injuries on their grapevines, an emerging threat to the state's $13 billion a year industry, NPR's Morning Edition reported Tuesday.

The damage likely originates from use of Monsanto's dicamba and Dow's 2,4-D formulations on nearby cotton fields. The companies sell cotton seeds that are genetically modified to withstand applications of the weedkillers. If farmers use the products improperly, the highly volatile chemicals can get picked up by the wind and land on off-target crops. When exposed to the herbicides, the leaves on non-target plants are often left cupped and distorted.

Conservation and public health groups sued the Trump administration and U.S. Environmental Protection Agency (EPA) chief Scott Pruitt on Wednesday for failing to protect endangered wildlife and the environment from the dangerous pesticide malathion.

The lawsuit, filed in the U.S. District Court for the Northern District of California, alleges that the EPA and the U.S. Fish and Wildlife Service have failed to complete the legally required steps to fully assess and limit the dangers of the neurotoxin.

From Scott Pruitt to Betsy DeVos, President Donald Trump has notoriously appointed a slew of individuals with serious conflicts of interests with the departments they oversee.

The latest is Michael L. Dourson, Trump's pick to head the EPA's Office of Chemical Safety and Pollution Prevention, the government's chemical safety program. Media reports reveal that the toxicologist is under intense scrutiny for his extensive ties to the chemical industry and a resumé dotted with some of the biggest names in the field: Koch Industries Inc., Chevron Corp., Dow AgroSciences, DuPont and Monsanto.

In late March, U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt decided that his agency would not place an outright ban on a pesticide manufactured by Dow Chemical called chlorpyrifos.

The decision came after a federal court ordered the EPA to make a final decision on whether or not to ban the pesticide, which the Obama administration had proposed banning in 2015. The chemical has been on the market in the U.S. since 1965 under the brand name Lorsban and indoor use of the chemical has been banned for more than a decade.

U.S. Environmental Protection Agency (EPA) administrator Scott Pruitt met with Dow Chemical CEO Andrew Liveris before deciding to reverse an earlier EPA decision to ban the company's toxic and widely used pesticide, chlorpyrifos.

According to records obtained by the Associated Press, the EPA boss met with Liveris for about 30 minutes at a Houston hotel on March 9. Later that month, Pruitt announced that he would no longer pursue a ban on chlorpyrifos from being used on food, ignoring his agency's own review that even small amounts of the pesticide could impact fetus and infant brain development.

In March, EPA chief Scott Pruitt scrapped his own agency's proposal to ban chlorpyrifos.

More than 50 agricultural workers southwest of Bakersfield, California in Kern County were inadvertently exposed to pesticide drift from a nearby field earlier this month. According to local reports, 12 farmworkers reported symptoms of vomiting, nausea and one person fainted due to exposure to Vulcan, an organophosphate-based chemical.

Wineries in Texas are worried that federal approval of two highly volatile and drift-prone herbicides used on neighboring genetically modified (GMO) cotton fields will cause widespread damage to their vineyards, The Texas Tribune details.

The herbicides in question are Monsanto's dicamba-based XtendiMax with VaporGrip Technology, which was approved in November by the U.S. Environmental Protection Agency (EPA), and Dow AgroSciences' 2,4-D-based Enlist Duo, which the EPA also proposed to register for use on GMO cotton seeds. Enlist Duo is already used on GMO corn and soybean crops in 15 states.

"The approval of these formulations will wind up affecting every vineyard up there," explained Paul Bonarrigo, a Hale County vintner who believes that his withering grapevines have been damaged by the illegal spraying of dicamba and 2,4-D on nearby cotton farms. Bonarrigo believes that the state's $2 billion wine industry is in jeopardy.

The debacle is yet another chapter in the expanding issue of herbicide-resistant weeds, or superweeds, that have evolved to resist the herbicide glyphosate, or Roundup. In response to weeds such as pigweed that have infested farms across the U.S., agribusinesses such as Monsanto and Dow have developed ever stronger weedkillers to help farmers.

As noble as that might sound, Monsanto was especially criticized when it decided to sell its dicamba- and glyphosate-resistant soybean and cotton seeds to farmers before securing EPA approval for the herbicide designed to go along with it. Bollgard II XtendFlex cotton was introduced in 2015 and Roundup Ready 2 Xtend soybeans was introduced earlier this year.

Without having the proper herbicide, cotton and soy farmers resorted to spraying older versions of dicamba on their crops. But dicamba, as well as the herbicide 2,4-D, are extremely prone to drift, meaning the chemicals can be picked up by the wind and land on neighboring fields that cannot withstand the chemical damage. When exposed to the herbicide, leaves on non-target plants are often left cupped and distorted.

Researchers from Ohio State University published a study in September showing that herbicide spray drift from the 2,4-D and dicamba can severely damage wine grape plants near agronomic crops.

Although Monsanto said it warned farmers against illegal dicamba spraying, this past summer, dicamba drift caused 10 states to report widespread damage on thousands of acres of non-target crops such as peaches, tomatoes, cantaloupes, watermelons, rice, cotton, peas, peanuts, alfalfa and soybeans.

Last month, Missouri's largest peach grower filed a lawsuit against Monsanto over claims that dicamba drift damaged more than 7,000 peach trees on the farm, amounting to $1.5 million in losses. This year, the farm said it lost more than 30,000 trees, with financial losses estimated in the millions.

Regulators assured to The Texas Tribune that the new pesticides are less likely to vaporize and drift, and the risk of damage will lessen if farmers follow safety precautions.

"I don't see this as being any more of an issue than what we have today," Steve Verett, executive vice president of the Plains Cotton Growers, told the publication. "I understand there are other sensitive crops as well. No matter what the product is or the farmer that's spraying, they need to make sure that the product they're spraying stays on their farm."

Kyel Richard, a spokesman for Monsanto, added that the company has conducted training exercises and education efforts to minimize "the opportunity for movement off- site and ensuring those herbicides are staying on target and controlling those weeds on the field that they're intended for."

State wineries, however, are worried that with the EPA's approval, use of dicamba and 2,4-D will expand to include 3.7 million acres of cotton fields.

"I could see it basically killing the [wine] industry, honestly," Garrett Irwin, owner of Cerro Santo vineyard in Lubbock County, countered. "If we get the levels of damage that I'm afraid we'll get, vineyards will not be able to recover or produce grapes at any sustainable level, and we're just going to have to go away."

Irwin also commented that cotton and soy farmers are likely to stick with old dicamba and 2,4-D herbicides because the new formulations are more expensive. Additionally, farmers have to upgrade their equipment with anti-drift nozzles to use the new products.

"I honestly don't think farmers will buy the new formulations when older labels that cost less are available and just as effective as the new labels," he said. "In short, I think farmers will buy generic chemicals without the additives to save money because the cotton won't know the difference."

And if they do buy the new herbicides, there will still be some farmers who "will do nothing to correct for negligence in spraying," Irwin said.

Pheasant Ridge Valley winery owner Bobby Cox told The Texas Tribune that he is worried that cotton farmers will have no choice but to switch to the new seeds system.

Cox said that 2,4-D drift in 2015 caused the amount of sugar in his grapes to be about 5 percent less than ideal.

"It will be catastrophic not only to vineyards but to oak trees, to pecan orchards, to shrubs," Cox said. "If they apply the amount of 2,4-D that they did Roundup and are equally irresponsible with that, it will kill everything green up here. I wish people would understand how important wine growing is for this area, how wonderful of a crop it is on the High Plains. It would be a shame to lose it when we're starting to get recognized."

Not only that, environmental experts worry about dicamba's threat on biodiversity and wonder if pesticide-makers are just creating another cycle of herbicide resistance.

"Once again the EPA is allowing for staggering increases in pesticide use that will undoubtedly harm our nation's most imperiled plants and animals," said Nathan Donley, a scientist with the Center for Biological Diversity, after the EPA approved the Xtend weedkiller. "Iconic species like endangered whooping cranes are known to visit soybean fields, and now they'd be exposed to this toxic herbicide at levels they've never seen before."

"We can't spray our way out of this problem. We need to get off the pesticide treadmill," he continued. "Pesticide resistant superweeds are a serious threat to our farmers, and piling on more pesticides will just result in superweeds resistant to more pesticides. We can't fight evolution—it's a losing strategy."
