(Beyond Pesticides, November 29, 2011) New research shows that women who drink water containing the widely used herbicide atrazine may be more likely to have irregular menstrual cycles and low estrogen levels, even at concentrations far below federal drinking water standards considered safe by the U.S. Environmental Protection Agency (EPA). Researchers compared women living in Illinois farm towns where atrazine is used regularly to women living in Vermont where the herbicide is used sparingly, and found that the women in Illinois were almost five times more likely to report irregular menstrual cycles, including more than six weeks between periods. Consumption of over two cups of unfiltered Illinois water daily was associated with increased risk of irregular periods. The study, entitled “Menstrual cycle characteristics and reproductive hormone levels in women exposed to atrazine in drinking water,” was published in the journal Environmental Research earlier this month, and is based on municipal tap water tested between July and September of 2005. In the study, participants maintained menstrual cycle diaries, answered a questionnaire, and provided daily urine samples for analyses of luteinizing hormone and estradiol and progesterone metabolites. To measure exposure, analysts looked at the state of residence, concentrations of atrazine and chlorotriazine […]

(Beyond Pesticides, November 23, 2011) A Federal Court of Canada has ordered Health Canada -the nation’s public health department- to take a second look at the impacts on amphibians of glyphosate-based pesticides, one of the most widely-used pesticides in Canada and the U.S., which includes products like Monsanto’s Roundup. The decision was the result of an action brought by a pesticide-activist and pediatrician, Josette Wier, M.D., and orders Health Canada to address requests by the public for a review of the safety of a pesticide where there is serious scientific concern about its risks. Dr. Wier’s legal challenge focused on wetlands that provide critical habitat for many species of frogs and amphibians. The original request for a special review of glyphosate-pesticides, especially those containing the “inert” ingredient polyoxyethyleneamine (POEA), and a subsequent 2009 legal challenge was brought because of her concern about possible aerial spraying of Monsanto’s pesticide in the forests near her community in Smithers. In her suit, Dr. Weir stated that the evidence “challenges the scientific validity of the previous evaluations” that led to the registration of the glyphosate herbicides containing POEA. Judge Michael Kelen of the Federal Court of Canada in his decision wrote, “[Dr. Wier] is […]

(Beyond Pesticides, November 8, 2011) The Environmental Protection Agency (EPA) published a petition to ban the endocrine (hormone) disrupting herbicide atrazine on September 14, 2011, opening a 60-day comment period for the public to weigh-in on the issue that ends Friday. Tell EPA that because atrazine poses unacceptable risks to humans and wildlife, the agency should remove this hazardous pesticide from the market immediately. Submit comments directly to EPA’s atrazine petition docket by November 14, 2011 or sign your organization or business onto Beyond Pesticides’ comments by Friday, November 11. According to its Federal Register notice, EPA received a petition from the non-profit organization Save the Frogs that includes over 10,000 signatures and select statements from the public, as well as two brief summaries of published literature, one by Jason Rohr, PhD (University of South Florida), and one by Tyrone Hayes, PhD (University of California, Berkeley), that is co-authored by 39 other scientists. In conjunction with the petition, EPA received nearly 50,000 emails from supporters of the Center for Biological Diversity and the Natural Resources Defense Council requesting that EPA “immediately take steps to phase out atrazine use in the United States,” stating that atrazine poses an unreasonable risk to […]

(Beyond Pesticides, October 26, 2011) A new report highlights scientific research and empirical experiences around the globe that demonstrate the failure of genetically modified (GM) seeds and crops to deliver on their advertised promises to increase yields, reduce pesticide usage, and tolerate drought with “climate ready” traits. A Global Citizens Report on the State of GMOs, “The GMO Emperor has no Clothes,” states that the on-the-ground experience in many countries discloses that GM technology has failed on all fronts, contrary to industry claims. The examples from around the globe include the financial burden borne by farmers. The report describes the cultivation of GM cotton in South Africa where the majority of farmers growing GM cotton are now in debt due to the high costs of seed, chemical, and other farm inputs. The Global Citizens Report confirms that such experiences are repeated in many countries and regions. The stories of Indian farmer indebtedness and increased suicides further emphasize the tragic costs of failed GM technology and its promises. The prevalence of Roundup Ready GM crops has led to the increases of Roundup resistant weeds in the environment. Farmers and agronomists throughout the world are alarmed by the growing epidemic of “superweeds” […]

(Beyond Pesticides, October 20, 2011) The Center for Biological Diversity filed a lawsuit yesterday against the Environmental Protection Agency (EPA) and U.S. Fish and Wildlife Service (FWS) for failing to evaluate and act on threats to the threatened California red-legged frog posed by more than 60 toxic pesticides used in and near its habitats. The Center had announced its intent to sue the two agencies back in December 2010. A 2006 legal settlement secured by the Center requires EPA to assess the impacts of harmful pesticides on red-legged frogs and formally consult with the Fish and Wildlife Service to address those impacts. EPA determined that widespread use of more than 60 pesticides is likely harming red-legged frogs, but since the agency and the Fish and Wildlife Service have failed to complete the required evaluations, no permanent protections for frogs have been put in place. “Federal agencies acknowledge that scores of pesticides may harm California’s rare red-legged frogs, but for years now they’ve neglected to complete biological evaluations of the effects of these chemicals,” said Jeff Miller, a conservation advocate with the Center. “California’s imperiled frogs are suffering as a result.” “Biological opinions,” the evaluations required by the Endangered Species Act, […]

(Beyond Pesticides, October 18, 2011) The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) recently announced the availability of a draft environmental impact statement (EIS) that evaluates the potential environmental effects of deregulating (commercializing) sugar beets genetically engineered (GE) to be resistant to the herbicide glyphosate, commonly referred to as Roundup Ready (RR) sugar beets. APHIS considered three alternatives in the draft EIS: deny the petition seeking a determination of nonregulated status (prohibit commercial planting), make a determination of nonregulated status (allow commercial planting), or extend the partial deregulation of RR sugar beets for the root crop, with mandatory conditions and restrictions. Comments will be accepted until December 13, 2011. APHIS originally deregulated RR sugar beets in 2005. A coalition of environmental groups and organic seed companies, led by the Center for Food Safety, challenged the USDA approval in 2008. It argued that GE sugar beets would contaminate organic and non-GE farmers of related crops, such as table beets and chard, as well as increase pesticide impacts on the environment and worsen the current Roundup-resistant “superweeds” epidemic in U.S. agriculture. In September 2009, Judge Jeffrey S. White in the federal district court in San Francisco agreed, […]

(Beyond Pesticides, September 16, 2011) The U.S. Environmental Protection Agency (EPA) announced earlier this week that it is seeking public comments on a petition to ban atrazine, one of the most widely used herbicides in the United States. The call for comments was prompted by a petition submitted earlier this year by the group SAVE THE FROGS!, to ban the highly toxic chemical. The group, along its allies, delivered over 60,000 petition signatures and emails to EPA requesting an immediate ban. The group organized a rally at the steps of the EPA’s headquarters in Washington, DC back in April to raise awareness of the disappearance of amphibians and call for a federal ban on atrazine on the occasion of the international Save The Frogs Day. Amphibian populations worldwide have been declining at unprecedented rates, and nearly one-third of the world’s amphibian species are threatened with extinction. “Now that we have the EPA’s attention, we are a large step closer towards protecting our food supply, our drinking water and our wildlife from this known endocrine-disruptor,” says Kerry Kriger, PhD, founder and executive director of SAVE THE FROGS! “However, only a few percent of Americans have ever heard of atrazine, so raising […]

(Beyond Pesticides, August 4, 2011) At least 21 different species of weeds are found to be resistant to the herbicide glyphosate, commonly sold as Roundup and used across thousands of acres of “RoundUp Ready” genetically engineered (GE) crops, according to a series of studies in the current issue of Weed Science. Palmer amaranth, one of the weeds discussed in the journal, can reduce yields of cotton by more than 50 percent if there is a density of at least 10 of these weeds per row. Fifty-two counties in the state of Georgia had infestations of glyphosate-resistant Palmer amaranth last year. Studies confirm that the weed, which also competes with soybean, corn, grain sorghum and peanut crops, is also resistant to the herbicide phrithiobac in addition to glyphosate. Over-application and over-reliance by farmers on glyphosate to solve all of their weed problems has led to the proliferation of so-called “super weeds,” which have evolved to survive the treatments through repeated exposure. The most common species which have evolved these traits include pigweed (palmer amaranth), mare’s tail, and ryegrass. The spread of resistance is what has led farmers to increasingly rely on more toxic alternative mixtures, including weed killers like atrazine. There […]

(Beyond Pesticides, July 19, 2011) According to a U.S. Department of Agriculture (USDA) study published in the Journal of Environmental Quality, the volatilization of atrazine and metolachlor, two herbicides known to contaminate surface and ground water, consistently results in herbicide movement off the target site that exceeds nontarget field runoff, varying widely depending upon weather conditions. Linked to endocrine disruption, cancer, developmental effects, and more, increased levels of these hazardous pesticides in the air is cause for concern. When averaged over the two herbicides, loss by volatilization is about 25 times larger than movement from surface runoff, despite low vapor pressures. Agricultural Research Service (ARS) soil scientist Timothy Gish, PhD and ARS micrometeorologist John Prueger, PhD led the investigation, which looks at the field dynamics of these two herbicides commonly used in corn production. Prior to this field study, many experts believed that volatilization was not a contributing factor to water contamination because atrazine and metolachlor had a low vapor pressure. However, the monitoring of both herbicide volatilization and surface runoff at the field-scale over multiple years had never been done. So the team set up a 10-year study in an experimental field in Beltsville that is equipped with remote […]

(Beyond Pesticides, July 6, 2011) After 27 years of fighting invasive weeds without the high-powered help of toxic chemicals, the Eugene district of the U.S. Bureau of Land Management (BLM) wants to add herbicides back into the toolkit. Eugene district BLM officials are proposing to use four herbicides to kill weeds along roadsides and in rights-of-way. The BLM stopped using herbicides in Oregon in 1984 after a court injunction in response to a lawsuit filed by the Northwest Coalition for Alternatives to Pesticides. The coalition had argued that the agency had not followed federal procedures in approving the use of herbicides on public lands, and a judge agreed. The BLM eventually wrote an environmental impact statement (EIS) on its proposal to use herbicides, but a final management plan wasn’t completed until last year. The BLM said it will only be doing ground application and not spraying herbicides by helicopter or plane. The management plan permits the agency to use 17 different herbicides to control weeds but only in limited circumstances. Now individual districts, including Eugene, are developing site-specific proposals for using chemicals. Locally, four herbicides are under consideration. Glyphosate, imazapyr, triclopyr, and clopyralid are effective on a range of plants, […]

(Beyond Pesticides, June 21, 2011) More than 130 groups in 35 states, representing public health, food-security, sustainable-farming, farmworker and conservation interests called on the Environmental Protection Agency (EPA) to use all the tools at its disposal to protect public health and imperiled wildlife from toxic pesticides. The June 16th letter to EPA, which was signed by Beyond Pesticides, cites significant flaws in the pesticide registration process. To see which conventional crops may be grown with pesticides linked to impacts on wildlife and human health, see Beyond Pesticides’ Eating with a Conscience food guide. “Pesticides pose a clear and preventable danger to our health and the environment. It’s time for EPA to ensure pesticides no longer jeopardize human health, wildlife, the water we drink or the air we breathe,” said Jeff Miller, a conservation advocate with the Center for Biological Diversity. “Congress must do its part by stopping legislation sponsored by chemical corporations and their allies to strip important laws that safeguard future generations, farmworkers and wildlife from pesticide harms.” The groups cite undue pesticide industry influence over EPA’s pesticide decisions under the Federal Insecticide Fungicide Rodenticide Act (FIFRA)””as well as documented pesticide impacts such as endocrine disruption, cancers and reproductive […]

(Beyond Pesticides, May 24, 2011) Last Friday, the U.S. Court of Appeals for the Ninth Circuit issued a summary order upholding a landmark legal decision requiring the U.S. Department of Agriculture (USDA) to conduct an Environmental Impact Statement (EIS) before approving the planting of genetically engineered (GE) crops. The decision upholds previous court rulings in favor of farmers and conservation advocates in a case on the future commercial uses of GE sugar beets, engineered to be resistant to Monsanto’s Roundup herbicide. “Today’s order cements a critical legal benchmark in the battle for meaningful oversight of biotech crops and food,” said Center for Food Safety (CFS) attorney George Kimbrell. “Because of this case, there will be public disclosure and debate on the harmful impacts of these pesticide-promoting crops, as well as legal protections for farmers threatened by contamination.” CFS, Organic Seed Alliance, High Mowing Organic Seeds, and the Sierra Club, represented by CFS and Earthjustice, challenged the USDA approval in 2008. They argued that GE sugar beets would contaminate organic and non-GE farmers of related crops, such as table beets and chard, as well as increase pesticide impacts on the environment and worsen the current Roundup-resistant “superweeds” epidemic in U.S. agriculture.

(Beyond Pesticides, May 9, 2011) The Endocrine Disruptor Exchange Inc. (TEDX), founded by Theo Colborn, PhD, has released a list of chemicals with the potential to affect the endocrine system. According to TEDX, every chemical on the TEDX List has one or more verified citations to published, accessible, primary scientific research demonstrating effects on the endocrine system. Endocrine disruptors are chemicals that impact traditional endocrine glands, their hormones and receptors such as estrogens, anti-androgens, and thyroid hormones. To date there are approximately 800 endocrine disruptors on the TEDX List. Download the TEDX List (Excel) Many everyday chemicals that people are exposed to can wreak havoc on the body’s endocrine system. Pesticides such as triclosan, atrazine, permethrin and many others have been associated with effects on the body’s hormone system. Visit the Pesticide Induced Disease Database for more on the chemicals linked to endocrine disruption. Endocrine effects include direct effects on traditional endocrine glands, their hormones and receptors such as estrogens, anti-androgens, and thyroid hormones, as well as signaling cascades that affect many of the body’s systems, including reproductive function and fetal development, the nervous system and behavior, the immune and metabolic systems, the liver, bones and many other organs, glands […]

(Beyond Pesticides, May 5, 2011) Over 70 international organizations, including health and environmental groups, landscapers and farmers are proclaiming tomorrow, Friday, May 6, 2011, Lawn Pesticide Awareness Day in honor of Dr. June Irwin’s leading role in passage of North America’s first lawn pesticide ban in Hudson, Quebec, on May 6, 1991. “The town of Hudson, Quebec, and particularly the actions of June Irwin, M.D., have sent a clear signal to communities all across North America that the use of lawn and landscape pesticides is both harmful and unnecessary,” said Jay Feldman, the founder of Beyond Pesticides of Washington, D.C. “Chemical lawn pesticides are scientifically linked to cancer in people and pets, and are known to be toxic to the nervous and immune system, endocrine disruptors, and tied to respiratory effects such as asthma. Alternative practices that rely on maintenance techniques and soil health that prevent unwanted insect and weeds are far more effective than their chemical counterparts.” Now, for 80 percent of Canadians and a growing number of Americans, synthetic chemical lawn pesticides are becoming a habit of the past. In 1991, exactly six years from the first day she voiced her concerns at a town meeting, May 6, […]

(Beyond Pesticides, April 28, 2011) In recognition of the 3rd annual Save the Frogs Day, a “Save the Frogs/Ban Atrazine Rally” will be held tomorrow, Friday, April 29th in Washington, DC. The rally will take place at the steps of the U.S. Environmental Protection Agency (1200 Pennsylvania Ave, NW), and is intended to raise awareness of the rapid disappearance of frog species worldwide, and bring attention to the harmful effects of the endocrine disrupting herbicide atrazine. Amphibian populations worldwide have been declining at unprecedented rates, and nearly one-third of the world’s amphibian species are threatened with extinction. Up to 200 species have completely disappeared in recent years. Amphibians are faced with an onslaught of environmental problems, including climate change, infectious diseases, habitat loss, invasive species, and over-harvesting for the pet and food trades. Numerous studies have definitively linked pesticide use with significant effects on amphibians. Pesticides can cause abnormalities, diseases, injury and death in these frogs and other amphibians. Because amphibians breathe through their permeable skin, they are especially vulnerable to chemical contamination. Frog eggs float exposed on the water surface, where pesticides tend to concentrate, and hatched larvae live solely in aquatic environments for five to seven months before […]

(Beyond Pesticides, April 14, 2011) Researchers at the University of South Florida have discovered that the most widely used fungicide in the U.S., chlorothalonil, is lethal to frogs even at low doses. Chemical pollution, according to the researchers, is considered the second greatest threat to aquatic and amphibious species in the U.S. Because many vital systems of amphibians are similar to those in humans, researchers believe that amphibians may be an underused model for studying the impacts of chemicals in the environment on human health and set out to quantify amphibian responses to chlorothalonil. The study, lead by Teagan McMahon, PhD, was published in Environmental Health Perspectives and opens the door for researchers to quantify the effects of the chemical on other species as well as other toxic pesticides on amphibian populations and human health. Researchers looked at Rana sphenocephala (Southern leopard frog) and Osteopilus septentrionalis (Cuban treefrog) in outdoor aquatic mesocosms (experimental water enclosures) with and without the expected environmental concentration as well as twice the amount of chlorothalonil. They also conducted two dose-response experiments on O. septentrionalis, Hyla squirella (squirrel treefrog), H. cinerea (green treefrogs), and R. sphenocephala, evaluating the effects of the fungicide on the stress hormone […]

(Beyond Pesticides, March 30, 2011) The Maryland House of Delegates passed the Fertilizer Use Act of 2011 (HB 573) on March 23 to limit ferilizer use on lawns, while a new report published by Environment Maryland Research and Policy Center finds that turf grass management, not agriculture, is the leading cause of fertilizer-based nitrogen runoff that pollutes the Chesapeake Bay. The report recommends an additional 30 percent reduction in nutrient levels in order to achieve a clean, sustainable Bay. The Maryland legislation would set limits on the amount of phosphorus and nitrogen in lawn-fertilizers and prohibit the application of lawn fertilizers within 15 feet of a waterway, when the ground is frozen, or between November 15 and March 1. the Maryland Senate version, SB 487, is now under consideration. Pollution in the Chesapeake Bay – which supports over 3,600 species of plants, fish, and other animals – increases when nutrients wash into its waters from snow and rainfall. And many synthetic lawn fertilizers, including ”˜weed and feed’ products, have an excess of two problematic nutrients, nitrogen and phosphorous. Maryland requires cities and farms to keep a close eye on nutrient runoff in the Chesapeake Bay, but the report, “Urban Fertilizers […]

(Beyond Pesticides, March 29, 2011) According to a French study published March 2, 2011 in the online edition of Environmental Health Perspectives, prenatal exposure to the herbicide atrazine is linked to small head circumference and fetal growth restriction. The authors say the study “raises particular concerns for countries where atrazine is still in use.” Atrazine is a widespread contaminant in drinking water and is linked to various birth defects, endocrine disruption and cancer, even at concentrations below EPA standards. Although it has been excluded from re-registration in the European Union because it is found above allowable thresholds in groundwater, it is still one of the most widely used herbicides in the U.S. and around world. The study, “Urinary Biomarkers of Prenatal Atrazine Exposure and Adverse Birth Outcomes in the PELAGIE Birth Cohort,” used a case-cohort design nested in a prospective birth cohort conducted in the Brittany region from 2002 through 2006. It collected maternal urine samples to examine pesticide exposure biomarkers before the 19th week of gestation. Quantifiable levels of atrazine were found in urine samples from 5.5% of 579 pregnant women, and various metabolites were identified in 20-40% of samples. The presence versus absence of quantifiable levels of atrazine […]

(Beyond Pesticides, March 10, 2011) The American Public Health Association (APHA) recently adopted 17 new policies at its 138th Annual Meeting in Denver, addressing a broad range of public health concerns, including a new policy calling for greater government action to protect the public from endocrine-disrupting chemicals (EDCs). The policy statement follows official positions released earlier in 2010 by both the American Medical Association (AMA) and the Endocrine Society in that more needs to be done to protect the public from endocrine-disrupting chemicals, or those that interfere with hormone action. Specifically, APHA urges: ”¢ Support for the Endocrine Society and the American Medical Association in proclaiming that more needs to be done to protect the public from potential health risks of exposure to EDCs. ”¢ That given the magnitude and urgency of the public health threat and the recognition that collectively EDCs likely will have common or overlapping effects on the endocrine system, steps should therefore be taken by federal agencies with regulatory oversight for various individual EDCs to coordinate and find synergies among themselves to coordinate and find synergy among federal agencies with regulatory oversight over various individual EDCs. ”¢ Health professionals and scientists with expertise in various aspects […]

(Beyond Pesticides, January 24, 2011) Citing the U.S. Environmental Protections Agency’s failure to protect over 200 endangered species from pesticides under the Endangered Species Act (ESA), two national environmental groups filed on January 20, 2011 a lawsuit to force agency implementation of the act. In what is penned by the groups, the Center for Biological Diversity and Pesticide Action Network North America (PANNA), as the most comprehensive legal action ever brought under ESA, the lawsuit specifically challenges EPA’s failure to consult with the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service on the impacts of hundreds of EPA-registered pesticides that are known to be harmful to endangered and threatened species. “For decades, the EPA has turned a blind eye to the disastrous effects pesticides can have on some of America’s rarest species,” said Jeff Miller, a conservation advocate with the Center. “This lawsuit is intended to force the EPA to follow the law and ensure that harmful chemicals are not sprayed in endangered species habitats.” According to EPA, the Endangered Species Act requires federal agencies, in consultation with FWS and/or the NOAA Fisheries Service, “to ensure that actions they authorize, fund, or carry out are not likely […]

(Beyond Pesticides, December 16, 2010)The Center for Biological Diversity notified the U.S. Fish and Wildlife Service (USFWS) and U.S. Environmental Protection Agency (EPA) December 15 of its intent to sue the agencies for failing to study and act on threats posed by more than 60 pesticides to the threatened California red-legged frog. A 2006 legal settlement secured by the Center required the EPA to assess the impacts of pesticides on the frog, then consult with the U.S. Fish and Wildlife Service (USFWS) under the Endangered Species Act to address those impacts, by 2009. The completed assessments were submitted to the Wildlife Service between March 2007 and October 2009. Although EPA determined that 64 registered pesticides are likely to harm the frogs, the Service has not completed any consultations or adopted protective measures. “The EPA acknowledges that scores of pesticides may be dangerous to California’s rare red-legged frogs, but nothing’s been done about it,” said Jeff Miller, a conservation advocate with the Center. “This three-year delay violates the Endangered Species Act and jeopardizes the future of the largest native frog in California.” Historically abundant throughout California, red-legged frogs have declined in numbers over 90 percent and have disappeared from 70 percent […]

(Beyond Pesticides, December 8, 2010) A new study finds that oral contraceptives are not the main culprit in estrogenic pollution of U.S. rivers and drinking water. Instead, the contribution of contraceptives is quite small compared to other human, industrial and agricultural sources, including pesticides. Recent observed feminization of aquatic animals has raised concerns about estrogenic compounds in water supplies and the potential for these chemicals to reach drinking water. Public perception frequently attributes this feminization to oral contraceptives (OCs) in wastewater and raises concerns that exposure to OCs in drinking water may contribute to the recent rise in human reproductive problems. Studies have suggested that long-term exposure to low levels of estrogens in water may adversely affect human health. This new information eases concerns that contraceptives are a major factor contributing to feminized fish and frogs. This study, “Are Oral Contraceptives a Significant Contributor to the Estrogenicity of Drinking Water?” reviews the literature regarding various sources of estrogens, in surface, source and drinking water, to determine whether OCs were the source of estrogen in surface waters, with an emphasis on the active molecule that comes from OCs. The authors find that industrial and agricultural sources not only discharge estrogens, but […]

(Beyond Pesticides, July 21, 2010) Alaska’s Supreme Court halted plans to use glyphosate to kill weeds along track owned by the Alaska Railroad, which is believed to be the only herbicide-free stretch of rail in the country. This decision is in response to an emergency petition filed by Alaska Community Action on Toxics (ACAT) and others against the Alaska Department of Environmental Conservation and the Alaska Railroad Corporation (ARC) who requested the use of glyphosate for weed control. On June 2, 2010, ACAT joined with other community groups in challenging a permit that would allow the Alaska Railroad to spray toxic herbicides along the railbelt from Seward to Indian for the first time in 26 years. On July 14, 2010, the court ordered a temporary temporary restraining order and prelminary injunction for the planned spray program, in response to an emergency petition (and memorandum of points and authorities) filed by Alaska Community Action on Toxics, Alaska Center for the Environment, Alaska Survival, Cook InletKeeper and the Native Village of Eklutna. The Alaska Railroad Corporation requested permission to use the herbicide glyphosate, the active ingredient in Roundup and Agri-Dex, along a 90 mile stretch of its track between Seward and Indian. […]
