(Beyond Pesticides, July 1, 2024) Comments on proposed new dicamba uses are due Friday, July 5 The U.S. Environmental Protection Agency (EPA) is accepting public comments until July 5 on whether it should allow the expanded use of the weed killer dicamba, which has been associated with adverse impacts related to its propensity to drift off of the target application site. The comment period addresses a BASF chemical company proposal for additional food use of a dicamba product on dicamba-tolerant cotton and dicamba-tolerant soybeans. (See Beyond Pesticides’ comments.) This application is similar to Bayer CropScience’s application for XtendiMax®, for which Beyond Pesticides submitted comments in June. The proposed label for BASF’s Engenia® allows for application preplant, at-planting, preemergence, and postemergence (in-crop) for broadleaf weeds. >> Tell EPA to ban use of dicamba and other drift-prone pesticides. The U.S. Supreme Court Reversal This proposal is under consideration on the heels of a U.S. Supreme Court decision on June 28 that reverses a 40-year old decision in Chevron v. Natural Resources Defense Council, which created a deference to federal agencies in the rulemaking process. In the dissent to this 6-3 decision of the court, the dissenters focus on the role of executive […]

With elections coming up in European Union Parliament and EU member state nations across the continent, advocates believe in the importance of proactive actions local governments and towns launch to address the cascading crises of climate change, biodiversity deterioration, and public health fragility. In the U.S., Beyond Pesticides is working with communities nationwide, providing hands-on technical assistance in the adoption of organic land management practices. “In recent years, our municipality has begun to explore the possibility of tackling an increasing number of city management problems with environmentally friendly solutions,” says Sándor Elek, mayor of Törökbálint in a public statement announcing the city’s membership. “We are phasing out chemical treatments in public areas and working on the continuous information and awareness-raising of the public. We are also working to promote the public acceptance of environmentally friendly mosquito control.” In joining the European Pesticide Free Towns Network, each […]

(Beyond Pesticides, June 24, 2024) National Pollinator Week ended last week, but the crisis associated with pollinator decline and biodiversity collapse continues. If there were not enough data to prove that regulators are woefully behind the curve in protecting pollinators, yet another study was published during Pollinator Week that reminded regulators, elected officials, farmers, gardeners, all eaters, and lovers of nature that federal, state, and local environmental laws in place have been an abject and unconscionable failure in protecting the biodiversity that supports all life. The study, “Insecticides, more than herbicides, land use, and climate, are associated with declines in butterfly species richness and abundance in the American Midwest,” published in PLOS ONE, cries out as a further warning that the U.S. Environmental Protection Agency’s (EPA) “mitigation measures,” which tinker with limited pesticide restrictions, represent a catastrophic disregard for the scientifically documented facts, according to environmental advocates. Daily News will cover this study in more detail in a later piece, however, the abstract of the journal piece is worth reprinting here in reflecting on Pollinator Week: “Mounting evidence shows overall insect abundances are in decline globally. Habitat loss, climate change, and pesticides have all been implicated, but their relative effects […]

(Beyond Pesticides, June 21, 2024) A recent review of the scientific literature, published in Science of The Total Environment, analyzes multiple species of bees on a molecular level to better understand the poisoning mechanisms that could, as the authors see it, inform chemical risk assessments with more precision. The mechanisms “implicated in the tolerance of bees to specific pesticides, and thus as determinants of insecticide sensitivity, … include metabolic detoxification, insecticide target proteins, the insect cuticle and bee gut microbiota,” the authors write. This review references more than 90 studies performed over the last 30+ years, with most being published in the last 5-10 years, as the understanding and importance of molecular determinants of bee sensitivity has emerged. Pollinators, such as bees, provide crucial ecosystem services by pollinating both wild plants and essential crops. The exposure these insects are subjected to threatens their existence, which occurs through pesticide contamination that can lead to impacts on growth and development or even colony collapse.    “While bees have only been exposed to human-made pesticides over the recent past (last 80 years) they have co-evolved with plants and fungi which produce a range of xenobiotics, including plant allelochemicals and mycotoxins,” the authors state. […]

(Beyond Pesticides, June 18, 2024) As part of its update to the proposed U.S. Environmental Protection Agency (EPA) Endangered Species Act (ESA) Workplan, the agency held a public webinar on June 18, 2024, which provided an overview of the agency’s “Mitigation Menu Website” for “reducing pesticide exposure to nontarget species from agricultural crop uses.” [Check back to see webinar when posted by EPA.] After court decisions forced EPA to develop a strategy to meet its statutory responsibility to protect endangered species from pesticide use, the agency recognized that it is, in its own words, “unable to keep pace” with its legal obligations. Despite this acknowledgement, the agency said it would “provide flexibility to growers to choose mitigations that work best for their situation.” In this spirit, a range of people, including grower groups, gathered earlier in the year for a series of workshops in the Pacific Northwest to discuss possible mitigation measures. According to a report written by commercial beekeeper Steve Ellis (more background), concrete decisions were not reached at the workshops as participants recognized the complexities in crafting pesticide product label restrictions to protect endangered species. Mr. Ellis concluded: “If it’s so complex that it’s impossible, then no one […]

Calls for Holistic Environmental Justice and a Shift Away from Societal Dependence on Petrochemical Pesticides and Fertilizers (Beyond Pesticides, June 18-19, 2024) Juneteenth (June 19) commemorates the date in 1865 when the enslavement of Black Americans ended in the westernmost Confederate state of Texas, over two and a half years after the Emancipation Proclamation of 1863 and the defeat of the Confederacy on April 9, 1865. On June 19, 1865, Union Major General Gordon Granger brought federal troops to Galveston, Texas and finally, and belatedly, implemented the Emancipation Proclamation, which proclaimed on January 1, 1863 freedom from slavery across the nation. Carl Mack, PhD, a historian and former President of the Seattle-King County NAACP, reminds us that there were still 225,000 enslaved Black Americans in Kentucky and Delaware after June 19, 1865 and the end of the Civil War until December 6, 1865 when Georgia became the 27th state to ratify the 13th amendment. “That is the day in which Georgia ratified the 13th amendment,” Dr. Mack goes on to discuss the remaining three former border states on their progress in adopting the 13th amendment. “As it applies to Delaware and Kentucky, Delaware did not ratify the 13th amendment until […]

(Beyond Pesticides, June 17, 2024) Every year, Beyond Pesticides announces National Pollinator Week—this year beginning today, June 17—to remind eaters of food, gardeners, farmers, communities (including park districts to school districts), civic organizations, responsible corporations, policy makers, and legislators that there are actions that can be taken that are transformative. All the opportunities for action to protect pollinators, and the ecosystems that are critical to their survival, can collectively be transformational in eliminating toxic pesticides that are major contributors to the collapse of biodiversity. This is why Beyond Pesticides starts most discussions and strategic actions for meaningful pollinator and biodiversity protection with the transition to practicing and supporting organic. In launching National Pollinator Week, Beyond Pesticides makes suggestions for individual actions to increase efforts to think and act holistically to protect the environment that supports pollinators. The impact that people have starts with grocery store purchases and the management of gardens, parks, playing fields, and pubic lands. The introduction of pesticides into our food supply and our managed lands has contributed to a downward spiral that is unsustainable. The good news is that it is now proven that we do not need toxic pesticides to grow food productively and profitably […]

(Beyond Pesticides, June 14, 2024) The influence of the chemical industry over public policy and regulation, especially in agriculture, is glaringly obvious and has little popular support, yet no one can seem to do anything about it. Numerous analyses have detailed the ways this influence is applied—through lobbying and political donations including dark money; industry experts named to regulatory agency scientific advisory boards; and the massive public relations machines that create and sustain public uncertainty using the tobacco industry playbook revealed by Naomi Oreskes and Erik Conway in their 2010 book Merchants of Doubt. A more insidious tendril of industry influence is explained in U.S. Right to Know’s (USRTK) report, released this month, on pesticide manufacturers’ infiltration of the Entomological Society of America (ESA). The report, “Anatomy of a science meeting: How controversial pesticide research all but vanished from a major conference,” examines the ESA’s 2023 annual meeting—its program, sponsorships, presentations, panelists, poster sessions, meet-and-greets, budget, revenue sources, and other aspects of the event. What is revealed is a systematic and comprehensive industry presence throughout the society and its meeting. A direct consequence is the near-elimination of any scientific presentations addressing the effects of neonicotinoid pesticides on insects, particularly bees. […]

(Beyond Pesticides, June 13, 2024) A study published in Conservation Letters, a journal of the Society for Conservation Biology, exposes critical shortcomings in the U.S. Environmental Protection Agency’s (EPA) ecological risk assessment (ERA) process for modeling the risks that pesticides pose to bees and other pollinators. For the study, “Risk assessments underestimate threat of pesticides to wild bees,” researchers conducted a meta-analysis of toxicity data in EPA’s ECOTOX knowledgebase (ECOTOX), an EPA-hosted, publicly available resource with information on adverse effects of single chemical stressors to certain aquatic and terrestrial species. The meta-analysis found that the agency’s approach, which relies heavily on honey bee data from controlled laboratory studies, drastically underestimates the real-world threats from neonicotinoid insecticides (and likely other pesticides) to native bees and other pollinators. The study “challenges the reliability of surrogate species as predictors when extrapolating pesticide toxicity data to wild pollinators and recommends solutions to address the (a)biotic interactions occurring in nature that make such extrapolations unreliable in the ERA process.” Beyond Pesticides executive director Jay Feldman remarked, “EPA’s ecological risk assessment process is fundamentally flawed and puts thousands of bee species at risk of pesticide-caused population declines and extinctions.” Mr. Feldman continued, “This underscores the urgent […]

(Beyond Pesticides, June 10, 2024) Expanding the planting of genetically engineered crops is the major focus of “The Coordinated Framework for the Regulation of Biotechnology – Plan for Regulatory Reform under the Coordinated Framework for the Regulation of Biotechnology” (Framework), released in May by three federal agencies. In its Framework, the U.S. Department of Agriculture (USDA), the Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA) use the words “exempt” or “exemption” in reference to federal safety regulations 21 times. Then, another 21 times the agencies identify their efforts to “streamline” the process for bringing genetically engineered “plant-incorporated protectants” (PIPs) to market. Without including the word “resistance” even once, the Framework advances the interests of the biotech and allied industries, ignoring the serious scientific issues regarding health and environmental effects and the economic failure for farmers facing crop loss. Meanwhile, the issue of resistance is not new to EPA, which has for years acknowledged the resistance problem despite allowing continued weed resistance to weed killers used with herbicide-tolerant crops and insect resistance to the pesticides incorporated into plants.   >> Tell USDA, FDA, and EPA to replace agricultural provisions in the Framework with policies that discourage GE crops […]

(Beyond Pesticides, June 7, 2024) This week, climate scientist and former mayor of Mexico City Claudia Sheinbaum shattered a proverbial glass ceiling, emerging as the first woman president of Mexico.   The election of a woman with a background in environmental protection— who signed an accord promising Mexican farmers to uphold the ban on transgenic corn and replace glyphosate with safer alternatives this past April—did not happen in a vacuum. According to an article by CBS News, President-elect Sheinbaum shared the following wisdom in the middle of a downtown hotel as her polling lead became definitive:  “I do not make it alone. We’ve all made it, with our heroines who gave us our homeland, with our mothers, our daughters, and our granddaughters.” As the new president-elect steps into the leadership of a country grappling with the ravages of the climate crisis, we reflect on the leadership of women in advancing Beyond Pesticides’ mission to end the use of petrochemical pesticides and fertilizers.  Leading the Fight for Farmworker Justice—Dolores Huerta    Earlier this year, Acting Governor Eleni Kounalakis of California honored the lifelong efforts of 94-year-old social justice activist Dolores Huerta, joining Washington State in recognizing Huerta’s decades of leadership in the […]

(Beyond Pesticides, May 24, 2024) Even allegedly “low-toxicity” pesticides such as flupyradifurone (insecticide), azoxystrobin, and difenoconazole (fungicides) pose adverse health effects to solitary ground-nesting squash bees (Xenoglossa pruinose), according to a study published in Biological Sciences. Fungicide exposure led to less pollen collected per flower, while exposure to flupyradifurone (FPF) produced larger offspring (which make it more challenging for them to fly). Simultaneous exposure to the three pesticides “induced hyperactivity in female squash bees relative to both the control and single pesticide exposure, and reduced the number of emerging offspring per nest compared to individual pesticide treatments.” With United Nations Food and Agriculture Organizations-sponsored World Bee Day earlier this week, now more than ever advocates are calling for the elimination of toxic insecticide classes, such as neonicotinoids and butanolides, and their wholesale replacement with organic land management principles. This study was written by Sabrina Rondeau, PhD, postdoctoral Fellow in the Department of Biology at the University of Ottawa, and Nigel E. Raine, PhD, professor at University of Guelph’s School of Environmental Science. Published on March 20, 2024, the researchers delve into the individual and co-exposure impacts of two fungicides and one insecticide, which is important, given the documented synergistic effects […]

(Beyond Pesticides, May 23, 2024)  A study recently published in the journal Nature compared the impact of organic and conventional food production using eight environmental health indicators and found that organic food has a significantly lower environmental impact than conventional food production for six of the eight indicators, including a lower potential for contributing to acidification of the environment, energy use, and biodiversity loss. For the analysis, scientists reviewed 100 different “life cycle assessments” (LCA) of organic and conventionally grown food products from cradle-to-farm gate.    LCA is a commonly used methodology to estimate food production system impacts on the environment through resource depletion and pollutant emissions. The results—that organic food production is less impactful on the environment—add to the robust body of research that underscores the importance of organic farming to the development of a sustainable global food system while addressing climate change. Beyond Pesticides has long argued that one of the most powerful tools in fighting global warming is organic agriculture, as it sequesters atmospheric carbon, eliminates the use of fossil fuel-based synthetic fertilizers and synthetic pesticides, and provides environmental and human health benefits. This study and most of the 100 studies it evaluates, do not recognize that conventional […]

(Beyond Pesticides, May 16, 2024) In a recent study at the Institute of Biochemistry and Molecular Biology at Ulm University in Germany, published in Current Research in Toxicology, scientists exposed embryos of South African clawed frogs (Xenopus laevis) to three neonicotinoids (NEOs), which led to developmental effects down to a molecular level. These frogs are a well-established model species often used in ecotoxicology studies as bioindicators for overall environmental and ecosystem health. When amphibian species like Xenopus laevis are exposed to contaminants in the water, it leads to negative impacts in the food chain and harms biodiversity. The study concludes that exposure to NEOs directly or through contaminated water leaves entire ecosystems vulnerable.    The NEOs that the embryos were subjected to include imidacloprid (IMD), thiamethoxam (TMX), and its metabolite clothianidin (CLO). NEOs are a class of insecticides that target the central nervous system of insects and lead to death. These insecticides pose a potential hazard to nontarget organisms, such as animals and humans, since they are persistent in the environment and “are found in natural waters as well as in tap water and human urine in regions where NEOs are widely used,” this study states. The authors continue by […]

(Beyond Pesticides, April 26, 2024) Researchers build on existing research when assessing the relationship between long-term exposure to organophosphorus pesticides—widely used in food production and homes and gardens—and the human gut microbiome. In a new study published in Environmental Health, an interdisciplinary research team from University of California, Los Angeles determined, “that exposure to [organophosphorus pesticides] is associated with changes in the abundance of several bacterial groups and differential functional capacity in metabolic pathways supported by the human gut microbiome.” The study draws upon data from a “Parkinson’s, Environment and Gene study (PEG)” in which 190 participants were asked to submit fecal samples and answer interview questions. “[The study] was initially designed to investigate the etiology of Parkinson’s disease (PD) and participants were recruited in two study waves [‘over the full 10-year exposure window’]: 2001–2007 and 2012–2017. At baseline, [Parkinson’s disease] patients were diagnosed within the past 5 years and randomly selected community controls were also recruited,” the research team shares in their Methodology section. “Since 2017, we invited previous study participants who could be contacted to enroll in a pilot study of the gut microbiome. In addition, we invited a household or community member of [Parkinson’s] patients to participate.” […]

(Beyond Pesticides, April 25, 2024) In a study from earlier this year, “Pesticides: An alarming detrimental to health and environment,” scientists compiled research from 154 articles regarding pesticide use and the adverse effects they have on the environment and human health. Among the effects of the harmful pesticides described is genotoxicity—the alteration of genetic material that results in the mutations in DNA that cause cancer.  The authors state that “genotoxins are mutagenic chemicals, and exposure to them increases the risk of developing tumors, hormonal changes, DNA damage, and changes in the ovaries and eggs, all of which leading to cancers… The risk of DNA damage surges with increased genotoxicity in people exposed to pesticides.” In addition, the National Institute of Health states that all “pesticides are highly biologically active chemicals. They may interact with DNA and damage its structure.” Despite these documented risks, pesticide use continues to surge.  While phased out to a considerable extent after being widely used in agriculture and residential areas, organochlorine pesticides (OCPs) like dichlorodiphenyltrichloroethane (DDT) or its breakdown compound dichlorodiphenyldichloroethylene (DDE) continue to show up as residues in the environment and food supply. Symptoms in humans that have been exposed to these chemicals include: seizures, […]

(Beyond Pesticides, April 24, 2024) On April 16, 2024, the U.S. Environmental Protection Agency (EPA) posted an “update” to the Draft Herbicide Strategy Framework (Draft Herbicide Strategy Framework to Reduce Exposure of Federally Listed Endangered and Threatened Species and Designated Critical Habitats from the Use of Conventional Agricultural Herbicides) that was released last summer, weakening aspects of the agency’s efforts to “protect” endangered species from herbicide use. The update outlines three types of modifications to the Draft Strategy, including “simplifying” its approach, increasing growers’ “flexibility” when applying mitigation measures, and reducing the mitigation measures required in certain situations. By reducing the stringency of the Strategy, advocates are again questioning EPA’s commitment to fulfilling legal requirements under the Endangered Species Act (ESA) or protecting endangered species and their habitats in the midst of an unprecedented rate of global extinction. ESA is celebrated as one of the most far-reaching conservation laws globally, credited with preventing the extinction of 99 percent of those species the government targets for protection, according to the U.S. Fish and Wildlife Service (USFWS). ESA establishes a framework to categorize species as “endangered” or “threatened,” granting them specific protections. Under ESA, EPA is required to consult with relevant agencies […]

(Beyond Pesticides, April 10, 2024) Researchers in a 2024 Chemosphere study find synergistic relationships in certain chemical mixtures, particularly heptachlor and triallate and trifluralin and lindane at lower concentrations, respectively. “Investigators should consider additional binary data for acute toxicity and potential chronic health impacts on these mixture…which showed synergism at low levels,” the researchers conclude. “According to a Centers for Disease Control (CDC) assessment, more than 50 pesticides are detected in blood or urine samples from the US population,” Researchers point to a cause for concern. The findings come as no surprise to advocates who have urged an assessment of the potential synergistic impacts of pesticide mixtures in the regulation of pesticides. Researchers “used the exposure data from a complex operating site with legacy pesticide pollution to evaluate if Inhalation of pesticide mixtures released from such contaminated sites could pose a risk to human health, The component-based risk assessment approaches that rely on additivity can predict the actual risk of pesticides in a mixture, and The legacy organochlorine pesticides banned many years ago interact with registered and supposedly safe herbicides in a mixture.” The study site is “a pesticide packaging and handling facility” contaminated with the following pesticides (“historical and […]

(Beyond Pesticides, April 8, 2024) When Mexico in 2020 decided to protect its traditional varieties of corn for reasons of health, safety, environmental protection, and food sovereignty with the banning of the importation of genetically engineered (GE or GM-genetically modified) corn by 2024, the powerful biotech industry and the U.S. government began a concerted campaign to stop the country’s efforts. With the opposition spearheaded by BIO, “the world’s largest trade association representing biotechnology companies, academic institutions, state biotechnology centers and related organizations across the United States and in more than 30 other nations” (as described in its March 15 press release), including companies like Bayer/Monsanto, the U.S government is calling Mexico’s action a trade barrier. The U.S. is invoking the U.S.-Mexico-Canada Agreement (USMCA), the trade agreement that replaced the North America Free Trade Agreement (NAFTA) in 2020. This is just one of the latest examples of corporate power reigning over U.S. environmental and economic policies. Mexico has already announced a delay in the planned April 1 ban on the importation, production, distribution, and use of glyphosate. Interestingly, this is all happening despite reports that the Biden administration is seeking to “tackle corporate abuses,” which is apparently limited  to tax reform and […]

(Beyond Pesticides, March 20, 2024) A report by CBAN unpacks the ecosystem and wildlife health impacts of genetically engineered (GE) corn in the context of Mexico’s 2023 decision to stop its importation into the country. The phase out of genetically modified (GM) corn imports into Mexico was immediately challenged by the U.S. and Canadian governments as a trade violation under the 2020 U.S.-Mexico-Canada Agreement (USMCA), which replaced the North American Free Trade Agreement (NAFTA) as the primary vehicle for North American trade policy. In August 2023, the U.S. Trade Representative set up a dispute settlement panel under USMCA to stop Mexico from going forward with its ban. There has been no public update from the Office of the U.S. Trade Representative as of this writing. The CBAN report highlights the scientific rationale underpinning Mexico’s decision to “safeguard the integrity of native corn from GM contamination and to protect human health” with this ban. In 2020, Mexico announced a four-year phase-out of the weed killer glyphosate, which along with other petrochemical herbicides is integral to GM corn production. When Mexico’s Minister of the Environment announced the phase-out, he said it is part of an effort to transform the country’s food system […]

(Beyond Pesticides, March 11, 2024) Inside a recent disagreement between the Office of the Inspector (OIG) and the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs (OPP) on the agency’s review of pet flea and tick collars—leading to thousands of deaths and poisonings—is a basic question of the adequacy of pesticide regulation. The disagreement is over the cause of 105,354 incident reports, including 3,000 pet deaths and nearly 900 reports of human injury, and the February 2025 OIG report’s conclusion that “[EPA] has not provided assurance that they can be used without posing unreasonable adverse effects to the environment, including pets.” While the disagreement focuses on a number of EPA process failures, Beyond Pesticides urges that the findings advance the need for the agency to address a key element of chemical mixtures in pesticide products not currently evaluated, potential synergistic effects—the increased toxic potency created by pesticide and chemical combinations not captured by assessing product ingredients individually.  Key to the dispute is what many see as a foundational failure of EPA to evaluate the effect of pesticide mixtures and full formulations of pesticide end products, a longstanding criticism of the agency’s pesticide registration process, which focuses on pesticide products’ active […]

(Beyond Pesticides, March 6, 2024) With over 2,500 pet deaths and 900 reports of adverse effects to people, an Office of Inspector General (OIG) report, published on February 29, 2024, reveals multiple systemic failures by the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs (OPP), citing inadequate safety reviews of Seresto pet collars. The report, The EPA Needs to Determine Whether Seresto Pet Collars Pose an Unreasonable Risk to Pet Health, concludes, “The EPA’s response to reported pesticide incidents involving Seresto pet collars has not provided assurance that they can be used without posing unreasonable adverse effects to the environment, including pets.” At the time the animal effects made headlines in 2021, the agency defended the product’s registration, telling the media that, despite these incidents, EPA deemed Seresto collars “‘eligible for continued registration’ based on best available science, including incident data… No pesticide is completely without harm, but EPA ensures that there are measures on the product label that reduce risk.” Despite the scathing criticism, EPA maintains the position that it conducted an adequate review of the two active insecticide ingredients in the pet collars—the neurotoxic insecticide flumethrin, and the notorious neonicotinoid imidacloprid—proven to have adverse effects on the endocrine system as […]
