EPA’s Failure to Ban Glyphosate Keeps Burden of Protection with Consumers and Local and State Governments

(Beyond Pesticides, September 30, 2022) In late September, the U.S. Environmental Protection Agency (EPA) announced the withdrawal of its Interim Decision on glyphosate, the active ingredient in multiple herbicides, most notably Monsanto’s (now Bayer’s) Roundup. The action follows a slew of developments related to the herbicide, including: the 2015 International Agency for Research on Cancer’s declaration of its carcinogenicity; legal judgments and massive rewards to victims who developed cancers after chronic exposures; advocate efforts to get EPA to recognize the dangers of, and curtail, its use; and pushback from industry — most of the latter two coming in the form of litigation. The withdrawal of that Interim Decision means, on the ground that this harmful compound can continue to be used until a next regulatory review decision by EPA. Beyond Pesticides has long been engaged in education on and advocacy against glyphosate use, and was a plaintiff in the 2020 lawsuit, with the Center for Food Safety (CFS), et al., against EPA for this 2020 Interim Decision (ID). Under FIFRA (the Federal Insecticide, Fungicide and Rodenticide Act) each pesticide must be reviewed by EPA every 15 years “to ensure that existing pesticide products continue to perform their intended function without […]

New Evidence Shows Roundup Damages the Nervous System

(Beyond Pesticides, August 30, 2022) Minuscule amounts of the weed killer Roundup and its active ingredient glyphosate can result in damage to the nervous system, finds research led by scientists at Florida Atlantic University, published in Scientific Reports. As hundreds of millions of pounds of glyphosate continue to be sprayed on hundreds of millions of acres of land throughout the United States each year, recent data indicate that four out of five U.S. children and adults contain detectable levels of glyphosate in their bodies. The pesticide industry and its paid supporters tell Americans that although contamination is widespread, the levels found in humans are not cause for concern. This latest research significantly undermines that specious argument, finding impacts on critical nervous system processes at levels 300 times less than the the lowest suggested amount on the Roundup label. “It is concerning how little we understand about the impact of glyphosate on the nervous system,” said Akshay S. Naraine, MSc., coauthor and a PhD student at Florida Atlantic University. “More evidence is mounting for how prevalent exposure to glyphosate is, so this work hopefully pushes other researchers to expand on these findings and solidify where our concerns should be.”  To investigate […]

As Thyroid Cancer Cases Rise, Study Finds Pesticides Link

(Beyond Pesticides, August 26, 2022) New research from a team in California finds one-third of pesticides it reviewed — including glyphosate, paraquat dichloride, and oxyfluorfen — to be associated with the development of thyroid cancer. Researchers investigated the links between exposure to pesticides — including 29 that cause DNA cell damage — and the risk of this cancer. The researchers also find that in all the single-pollutant models they employed, paraquat dichloride — a widely used herbicide — was linked to this cancer. In 2021, Beyond Pesticides covered research by the U.S. National Institutes of Health (NIH) that demonstrated that exposures to lindane and metalaxyl also cause heightened risk of thyroid cancer. These study findings add to the already considerable concern about pervasive pesticide exposure — not only among farmers and applicators, but also in the general population. It is worth noting that, in addition to elevated thyroid cancer risks, multiple pesticides can cause other health damage. Paraquat is also acutely toxic, and can cause longer-term reproductive, renal, and hepatic damage to humans; it is toxic to birds, fish, and other aquatic organisms, and slightly so to honeybees. Glyphosate, as Beyond Pesticides has written frequently, is carcinogenic, and is associated […]

Glyphosate Weed Killer Crosses Blood-Brain Barrier, Linked to Alzheimer’s and Other Neurodegenerative Diseases

(Beyond Pesticides, August 4, 2022) An Arizona State University (ASU) study shows that the popular herbicide glyphosate can infiltrate the brain through the blood (blood-brain barrier), increasing neurological disease risk. The blood-brain barrier filters various molecules entering the brain from the circulatory system. However, the permeation of glyphosate molecules elevates the expression of TNFα and the accumulation of soluble beta-amyloid (Aβ) proteins in the brain and has associations with immune, inflammatory, and neurodegenerative diseases like Alzheimer’s disease (AD). More than 6 million people in the U.S. are living with Alzheimer’s, and cases are expected to double by 2050. Although Alzheimer’s research has focused heavily on finding genetic causes of the disease, fewer than half of cases are genetic. Thus, researchers are now evaluating how environmental contaminants may increase disease risk. Over 300 environmental contaminants and their byproducts, including pesticides, are chemicals commonly present in human blood and urine samples and can increase neurotoxicity risk when crossing the brain barrier. Therefore, studies like this highlight the importance of understanding how chemical accumulation in the body can impact long-term health and disease prognosis. The study notes, “Brain glyphosate correlates with increased TNFα levels, suggesting that exposure to this herbicide may trigger neuroinflammation in the brain, which may […]

Inspector General Finds Secret EPA Meetings with Industry and Use of Untested Science to Lower Cancer Risk for Dangerous Fumigant

(Beyond Pesticides, July 26, 2022) Secret meetings with industry, the elevation of unqualified individuals to decision-making roles, using an untested scientific approach, failing to conduct a simple literature review, and an overall absence of public transparency. This is how the U.S. Environmental Protection Agency’s (EPA) conducted its cancer review for the potent fumigant pesticide 1,3-Dichloropropane (1,3-D; brand name: Telone), according to a report from EPA’s Office of Inspector General (OIG). EPA’s actions allowed a product once considered to pose a 1 in 10,000 risk of cancer to Americans to increase exposure by 9,000% (from 7.7 ÎĽg/m3 to 690 ÎĽg/m3). “These departures from established standards during the cancer assessment for 1,3-D undermine the EPA’s credibility, as well as public confidence in and the transparency of the Agency’s scientific approaches, in its efforts to prevent unreasonable impacts on human health,” the OIG report states. Yet, even with the agency’s failings laid out in clear view, EPA’s lackluster response to OIG’s corrective actions in this case add insult to its injurious actions against public health. OIG initiated a review of EPA’s cancer assessment for 1,3-D after the submission of multiple complaints. 1,3-D is a highly toxic fumigant used on a variety of crops, […]

Four Out of Five People in U.S. Contaminated with Glyphosate

(Beyond Pesticides, July 12, 2022) More than four out of five U.S. children and adults over the age of six have detectable levels of glyphosate in their bodies, according to data recently published by the Centers for Disease Control and Prevention (CDC). With strong evidence implicating this chemical as a carcinogen, and emerging data associating it with adverse birth outcomes, the findings raise broad concerns for public health. As the U.S. Environmental Protection Agency (EPA) continues to permit widespread public exposure to toxic chemicals based on obscure economic arguments over the claimed benefits of pesticides, advocates say it is time for a change that embraces health and the environment over the profits of pesticide manufacturers. CDC’s testing data was developed as part of its National Health and Nutrition Examination Survey (NHANES), a long-running program that began in the early 1960s and has since become a continuous program focused on American health and nutrition measurements. Data from this program are subsequently analyzed to help inform the prevalence of disease in the U.S. population and are used to develop public health policies. A total of 2,310 urine samples retained from studies conducted in 2013-2014 were analyzed by NHANES researchers for the presence […]

Supreme Court Permits Large Jury Verdicts on Roundup, Appeals Court Finds EPA Registration Unlawful

(Beyond Pesticides, June 22, 2022) Bad news is piling up for Bayer (Monsanto) and its carcinogenic flagship weed killer, glyphosate (Roundup). Last week, the Court of Appeals for the Ninth Circuit handed down a ruling that held the U.S. Environmental Protection Agency’s (EPA) 2020 approval of its notorious weed killer glyphosate unlawful. Then, yesterday, the U.S. Supreme Court declined to consider (deny certiorari) Bayer’s “Hail Mary” petition attempt to save the company from being held accountable to those diagnosed with cancer after using Roundup (glyphosate) herbicides. In both cases, the courts are acting as a check on a company, while EPA regulators charged with stopping this behavior continue to rubber stamp the agrichemical industry’s dangerous decisions. This is not the first time that the Supreme Court has upheld the rights of victims of the pesticide industry. In 2004, Bates v. Dow Agrosciences (U.S. Supreme Court, No. 03-388), the court found: “The long history of tort litigation against manufacturers of poisonous substances adds force to the basic presump­tion against pre-emption. If Congress had intended to deprive injured parties of a long available form of compen­sation, it surely would have expressed that intent more clearly. See Silkwood v. Kerr-McGee Corp., 464 U. […]

Glyphosate Weed Killer Disrupts Bumblebees’ Nest Temperature, Leading to Colony Failure

(Beyond Pesticides, June 7, 2022) Bumblebee colonies exposed to low levels of the weed killer glyphosate are unable to adequately regulate nest temperature, imperiling the next generation of bumblebees and long-term colony growth and survival. This latest finding, published this month in the journal Science, is a stark reminder that a pesticide does not have to kill an animal outright in order to create effects that ultimately result in death and population declines. “Sublethal effects, i.e. effects on organisms that are not lethal but can be seen, for example, in the animals’ physiology or behaviour, can have a significant negative impact and should be taken into account when pesticides are approved in future,” said Anja WeidenmĂĽller, PhD, of the University of Konstanz, Germany. With regulators at the U.S. Environmental Protection Agency (EPA) refusing to adequately account for sublethal impacts, and myopically focused on the acute effects of pesticide exposure, bumblebee populations in the United States are in free fall and require urgent protective action. To better understand how glyphosate exposure affects bumblebee colony growth and brood (young larval bee) development, researchers first split colonies in two. One side of the colony was fed sugar water containing 5mg/liter of glyphosate, while […]

Environmental Pesticide Exposure Alters Gut Microbes, Increasing Urgency for Organic Transition

(Beyond Pesticides, May 12, 2022) A report published in Environmental Health finds that exposure to environmentally relevant concentrations of pesticides can alter gut microbial communities, as demonstrated through fecal samples. Over 300 environmental contaminants and their byproducts, including pesticides, are chemicals commonly present in human blood and urine samples. Ample evidence demonstrates that environmental contaminants, including pesticides, negatively affect the human mouth and gut microbes. However, fecal samples provide an accurate representation of the microbial community existing in the gut. These toxicants can alter hormone metabolism, which adversely affects health outcomes. Adverse health effects of environmental contaminants include reproductive and developmental defects, diabetes, cardiovascular disease, liver disease, obesity, thyroid disorders, and improper immune operation. Although studies show how chemical exposures affect human health, more research is now questioning how these toxic chemicals influence gut health. Therefore, studies like these highlight the importance of evaluating how chemical contaminants deregulate normal bodily function through microbiome changes. The report notes, “Our results highlight the need for future dietary intervention studies to understand effects of pesticide exposure on the gut microbiome and possible health consequences.” Researchers examined dietary exposure to 186 common pesticide residues in the fecal excrement to determine impacts on the microbiome among 65 twins in the United Kingdom.

Chemical No-Till Failure Due to Herbicide Resistance Increases Greenhouse Gas Emissions

(Beyond Pesticides, May 10, 2022) Widespread weed resistance on chemical corn and soybean farms is leading farmers to till their fields more often, significantly increasing greenhouse gas (GHG) emissions. These findings were published late last month in the journal Nature Food by a team of Iowa State University researchers. With agricultural practices accounting for roughly 10% of U.S. GHG emissions, and 25% of worldwide releases, farming practices that preserve soil health and sequester GHGs are essential for the future of food production. Tillage is a farming practice that can provide a range of benefits for crop production, but only in the right conditions. A range of tillage practices exist, ranging from yearly conventional tillage, where most crop residue is plowed into the soil, to conservation tillage where some residue remains, and no-till systems where the soil remains covered. Repeated tillage causes significant harm to soil structure and biology, and result in erosion and the release of GHGs like carbon dioxide, methane, and nitrous oxide from soil into the atmosphere. The harms of tillage have led both chemical and organic farmers toward no-till or reduced tillage systems. Organic no-till farming, as practiced by farming groups like the Rodale Institute, employs the […]

Glyphosate Breakdown Product, Associated with Oxidative Stress and DNA Damage Among Children

(Beyond Pesticides, April 28, 2022) A study in Environmental Research finds that glyphosate’s primary metabolite (breakdown product), aminomethylphosphonic acid (AMPA), induces DNA damage through oxidative stress among subpopulations of primary school children. Although pyrethroid and chlorpyrifos metabolites can induce oxidative stress, this study is the first to investigate AMPA’s association with adverse health effects, rather than solely the effects of the active ingredient, glyphosate, in Roundup and other formulations. Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulations, readily contaminating soil, water, food, and other resources. Chemical use has been increasing since the inception of crops genetically modified to tolerate glyphosate. However, studies demonstrate glyphosate is among the most prevalent pesticide contributors to human, biotic, and ecosystem harm. According to research, herbicide toxicity to invertebrates has doubled since 2004. Although research links glyphosate exposure to cancer, specifically non-Hodgkin lymphoma, much less research considers the effects that metabolites have on children who are more vulnerable to chemical exposure. Ecological and health risk assessments primarily focus on active ingredients in pesticide products, overlooking the potential impacts of metabolites. Thus, studies like these highlight the need to assess the implications of metabolite exposure to protect human, animal, and environmental health. The study notes, “Our […]

EPA Overlooks Glyphosate and Roundup Ingredients’ Cancer, DNA Damage, and Multigenerational Effects

(Beyond Pesticides, March 10, 2022) Glyphosate and glyphosate-based herbicides (GBH) like Roundup® induce DNA damage and alter biological mechanisms (gene regulatory microRNAs [miRNAs or miRs]) associated with cancer development. According to the study published in Toxicological Sciences, DNA damage mainly occurs through oxidative stress from GBH exposure. Moreover, DNA damage and other biological mechanisms that cause carcinogenicity (cancer) occur at doses assumed “safe” by pesticide regulators such as the U.S. Environmental Protection Agency (EPA). Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, not just Bayer’s (formerly Monsanto) Roundup®. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in food and water commodities. In addition to this study, literature proves time and time again that glyphosate has an association with cancer development, as well as human, biotic, and ecosystem harm.  Study lead author Michael Antoniou, Ph.D., cautions, “Our results are the first to simultaneously show glyphosate and Roundup toxicity in a whole mammalian animal model system and provide a mechanism – oxidative stress – by which DNA damage has been observed in other systems, such as mammalian […]

Pesticide Use on Crops for Meat and Dairy Feed Further Threatens Endangered Species

(Beyond Pesticides, March 1, 2022) A report by the Independent finds chemical-intensive farming of crops for animal feed puts thousands of endangered species at risk. U.S. farmlands use more than 235 million pounds of pesticide (i.e., herbicides and insecticides) solely for animal feed production, many of which are highly hazardous pesticides (HHPs). Several HHP hazard categories include acutely toxic, chronic health hazards, and environmental hazards. Therefore, animal feed production intensifies global pollution, increases pesticide exposure, and degrades human, animal, and ecological health.  Although the report demonstrates a need to eliminate toxic pesticide use for the sake of human, animal, and ecosystem health, it will take more than eliminating the worst chemicals to address the impending biodiversity collapse and the climate crisis. Experts highlight the need for an urgent shift to organic land and agricultural management practices. The study notes, “These pesticides are taking a toll on our environment and biodiversity. Endangered species like the highly imperiled whooping crane, monarch butterflies, all species of salmon, the rusty-patched bumble bee, the San Joaquin kit fox, and the northern long-eared bat, as examples, all face significant threats from industrial agricultural operations and the chemicals applied. In order to conserve biodiversity and better protect vulnerable species and their habitats, […]

One-Third of Americans Have Hazardous Weed Killer in Their Bodies

(Beyond Pesticides, February 15, 2022) A synthetic weed killer linked to cancer, endocrine (hormone) disruption, reproductive harm and birth defects can be found in the bodies of 1 in 3 Americans, according to research published in Environmental Health by scientists at George Washington University. The chemical in question is not glyphosate (though current data indicate similar results are likely) but 2,4-D, an herbicide that is increasingly used when weeds growing near genetically engineered  (GE) crops have developed resistance to the repeated use of Roundup and other glyphosate-based weed killers. “Our study suggests human exposures to 2,4-D have gone up significantly and they are predicted to rise even more in the future,” Marlaina Freisthler, a PhD student and researcher at the George Washington University, said. “These findings raise concerns with regard to whether this heavily used weed-killer might cause health problems, especially for young children who are very sensitive to chemical exposures.” Researchers conducted their analysis based on data from the National Health and Nutrition Examination Survey, which includes urinary concentrations of 2,4-D from 14,395 participants spanning 2001 to 2014. Between those years, the use of 2,4-D increased rapidly from its relative low point at the beginning of the century. “Roundup […]

Manatees in Florida Seriously Threatened from Pollution, Pesticides, and Other Human-Induced Stressors

(Beyond Pesticides, January 27, 2022) Wildlife officials in Florida have resorted to supplementing starving manatees with cabbage and lettuce in an attempt to keep their rapidly dwindling populations alive. Massive Red Tides exacerbated by runoff from urban and agricultural pollution have directly killed off dozens of manatees over the last several years, but the indirect effects of these harmful algae blooms have been most catastrophic, resulting in significant loss of the seagrass beds upon which manatees rely. While Florida Governor Ron DeSantis has announced plans to spend $481 million on water quality improvement projects, conservationists note that the funds are primarily directed toward point source wastewater treatment, and more is needed to address nonpoint source herbicide and fertilizer runoff from agricultural, and urban and suburban yards. Florida manatees, a subspecies of the West Indian manatee, can live as long as 60 years old, weigh up to 1,200 lbs, and have no natural predators within their range. The biggest threat to these peaceful marine mammals is human activity and environmental stressors. Unfortunately, the former is well-known to exacerbate the latter. Humans harm manatees primarily through boat strikes, but the animals can also die from eating or becoming entangled in fishing equipment, […]

Review Shows that Monsanto/Bayer Claims of Glyphosate Safety Not Supported by Credible Science 

(Beyond Pesticides, December 21, 2021)  A research team undertaking a review of industry-conducted glyphosate safety studies submitted to EU (European Union) regulators shows that most of the research fails to meet current international standards for scientific validity. The researchers find that of the 11 reviewed studies, which were submitted to regulators by Bayer AG (now owner of the Monsanto “Roundup” brand of glyphosate herbicide) and several other chemical companies, only two are scientifically “reliable”; six others are deemed “partly reliable,” and the remaining three, “not reliable.” These results go, in part, to the age of some of the studies (see below); but they also underscore the point Beyond Pesticides has made for years. Regulators, whether in the UK, the U.S., or anywhere else, ought not be relying solely and without adequate auditing on industry-generated and -funded safety research in making safety determinations that underlie regulations impacting the well-being of millions of people (and other organisms), never mind the environment writ large. The report, from a team working out of the Institute of Cancer Research (ICR) at the Medical University of Vienna, is timely: the European Food Safety Authority (EFSA) and European Chemicals Agency (ECHA) are currently considering whether or not […]

CA Supreme Court Upholds $87M Award in Glyphosate Damage Lawsuit, Bayer/Monsanto Challenge Fails

(Beyond Pesticides, November 30, 2021) The chronicle of developments in the glyphosate saga has just grown longer: the California Supreme Court has rejected a request by Bayer AG for review of the August 2021 First District Court of Appeal (San Francisco) ruling, for the plaintiffs, that Monsanto knowingly marketed a product — Roundup — whose active ingredient (glyphosate) could be dangerous. The $87 million in damages awarded to the plaintiffs in the litigation, Alberta and Alva Pilliod, has thus survived Bayer’s challenge. This highest state court decision racks up another loss for Bayer (which now owns the Monsanto “Roundup” brand) — despite its dogged insistence, throughout multiple lawsuits (with many more still in the pipeline), that glyphosate is safe. Beyond Pesticides has covered the glyphosate saga extensively; see its litigation archives for multiple articles on glyphosate lawsuits. Glyphosate has been the subject of a great deal of public, advocacy, and regulatory attention, as well as the target of thousands of lawsuits — particularly since the 2015 declaration by the IARC (International Agency for Research on Cancer) that the compound is a likely human carcinogen. In June 2020, facing approximately 125,000 suits for Roundup’s role in cancer outcomes, Bayer announced a $10 billion […]

Cover Crops Attract Pest Predators which Reduce Pesticide Use

(Beyond Pesticides, November 2, 2021) Cover crops create habitat that draw in pest predators and help mitigate crop injury, finds research published in the journals Agroecosystems and Biological Control from scientists at the University of Georgia. Expanded predator diversity can reduce pest pressure that drives conventional chemical farmers to apply toxic pesticides, and the authors of the study find the practice to be economically viable within these cropping systems. “There’s a motion of change going on where growers are thinking more about using natural systems instead of just using pesticides,” said co-author Jason Schmidt, PhD in a news release. “Producers must use all tools available to make a profit, so if they can promote beneficial insects in the system to aid in pest control,  fewer inputs are needed and that should lead to reduced costs of production. ” To determine how beneficial cover crops were to cotton production, researchers began with experimental crops established over two years in 2016 and 2017 in Georgia. Twelve cover crops plots were established with crimson clover and rye, while a plot not planted with cover crops was used as a control. Researchers planted the cover crop in early November after the previous cotton crop […]

Glyphosate Kills Microorganisms Beneficial to Plants, Animals, and Humans

(Beyond Pesticides, October 28, 2021) A study published in Frontiers in Environmental Science finds the popular herbicide glyphosate negatively affects microbial communities, indirectly influencing plant, animal, and human health. Exposure to sublethal concentrations of glyphosate shifts microbial community composition, destroying beneficial microorganisms while preserving pathogenic organisms. Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, including Bayer’s (formerly Monsanto) Roundup®. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in both food and water commodities. In addition to this study, the scientific literature commonly associates glyphosate with human, biotic, and ecosystem harm, as a doubling of toxic effects on invertebrates, like pollinators, has been recorded since 2004. The authors caution, “[O]utbreaks of several animal and plant diseases have been related to glyphosate accumulation in the environment. Long-term glyphosate effects have been underreported, and new standards will be needed for residues in plant and animal products and the environment.” With an increasing number of reports on the relationship between glyphosate and human health, including potential effects on the human gut microbiome, advocates are calling on global leaders to eliminate chemical […]

Stopping the Use of Toxic Pesticides in State Parks and Transition to Organic Land Management 

(Beyond Pesticides, October 18, 2021) The most recent science on pesticides raises serious health and environmental effects associated with pesticide use for lawn and landscape management. While the data is often not assembled in one place, updated factsheets bring together the science on the 40 commonly used pesticides used for conventional landscape management. Governors have the authority to stop the use of these hazardous materials that are used on parks and playgrounds, either by executive order or through their work with their state legislature, and transition land management to organic practices. Tell your governor to stop hazardous pesticide use on state lands and transition to organic land management. The new factsheets document with scientific citations a wide range of diseases and ecological effects linked to pesticides.

Commonly Used Neurotoxic Pesticide Exposure Increases ALS Risk to Workers and Residents

(Beyond Pesticides, September 30, 2021) Individuals working or living in areas with frequent neurotoxic pesticide use experience more amyotrophic lateral sclerosis (ALS) incidences than the general population. The study, published in NeuroToxicology, finds a positive association between sporadic (non-genetic, spontaneous) ALS incidences among individuals exposed to neurotoxic pesticides.  Amyotrophic lateral sclerosis (or Lou Gehrig’s disease) is a neurodegenerative disease that affects the nerves in the brain and spinal cord. As many as 16,000 – 20,000 Americans live with this condition, which weakens muscle/motor function leading to loss of muscle control for walking, talking, eating/swallowing, and breathing. Severe ALS progression is fatal and has no current cure. Although research supports genetic factors play a role in disease etiology (cause), most ALS cases do not result from genetic inheritance. Several research studies demonstrate exposure to environmental or work-related toxicants (i.e., pesticides) predispose humans to the disease. With researchers predicting a global ALS incidence increase of 69% by 2040, identifying ALS’s causal factors are important to future research. Therefore, research like this showcases the importance of assessing aggregate health risks associated with toxic chemical exposure, especially for illnesses, which are not curable. In this study, the researchers note, “[W]e identified pesticides applied to crops in the area of […]

EPA Urged to Stop Use of Misbranded “Minimum Risk” Pesticides, Step Up Oversight and Enforcement

(Beyond Pesticides, September 22, 2021) Health and environmental organizations are urging the U.S. Environmental Protection Agency (EPA) and state pesticide regulators to immediately stop the use and sale of dangerous and misbranded Eco-MIGHT and W.O.W. (Whack Out Weeds!) products, falsely labeled as 25(b) minimum risk. Recent laboratory testing by the state of California found the presence of hazardous pesticides, including glyphosate, bifenthrin, permethrin, cypermethrin, and carbaryl in these products. “From organic farmers to municipal landscapers and home gardeners, consumers employing minimum risk products are working intentionally to avoid the dangers associated with toxic pesticide exposure,” said Jay Feldman, executive director of Beyond Pesticides. “It is critical that EPA and state regulators coordinate to ensure the integrity of the minimum risk program.” Coordination is critical yet reports indicate that EPA is falling down on the job. The issue first came to light in late July, when the California Department of Food and Agriculture’s (CDFA) State Organic Program issued a Stop Use Notice to farmers alerting them to adultered Eco-MIGHT and W.O.W products. The products make a range of claims, marketed as “organic,” “natural,” “glyphosate-free,” and “non-toxic and safe.” As CDFA Secretary Karen Ross noted, “It is imperative that we alert California […]

(Beyond Pesticides, September 15, 2021) Toxic pesticide use, and glyphosate in particular, degrades the health of freshwater ecosystems by harming species that form the basis of aquatic food chains, according to research published by scientists at McGill University. In a series of studies, scientists investigated how freshwater bacteria and zooplankton were affected by varying levels the weed killer glyphosate, the neonicotinoid insecticide imidacloprid, and nutrient levels. “Because plankton form the foundation of the food chain in freshwater ecosystems, it is very important to understand how plankton communities respond to widely used pesticides,” said Jesse Shapiro, PhD, an Associate Professor in McGill’s Department of Microbiology and Immunology. “Our research shows that the structure of these communities can be impaired under currently acceptable North American water quality guidelines.” Two separate experiments were conducted under similar conditions in order to properly investigate the effects of pesticide exposure on either zooplankton or freshwater bacteria. For both studies, target species were exposed to varying rates of glyphosate, imidacloprid, or both chemicals at either high or low water nutrient levels. Researchers conducted this study by establishing a series of outdoor experimental ponds, intended to mimic freshwater ecosystems by using Lake water and evenly distributing organisms throughout […]
