(Beyond Pesticides, December 19, 2025) While still the exception rather than the norm, a growing movement of Christmas tree farmers across the United States is demonstrating that organically managed systems can also be applied when choosing a tree during this holiday season. Health and environmental advocates across the country are calling for a transition away from toxic pesticide dependency during the holiday season. Beyond Pesticides maintains a webpage, Christmas Trees and Pesticides, and Center for Biological Diversity and Alliance of Nurses for Healthy Environments urged the U.S. Environmental Protection Agency and U.S. Department of Health and Human Services to conduct a “special review of pesticides used on Christmas trees.” The groups sent a letter on December 4, the day the National Christmas Tree was lit at the White House, specifically citing the need to review the pesticides chlorpyrifos, carbaryl, dimethoate, bifenthrin, chlorothalonil, glyphosate, hexazinone, imidacloprid, simazine, and 2,4-D, among others. Christmas is one of the most celebrated holidays in the United States, with Christmas trees grown on Christmas tree farms being brought into homes as part of the celebration. On average, Americans purchase 25 to 30 million Christmas trees annually, according to the National Christmas Tree Association; however, certified organic […]

(Beyond Pesticides, December 12, 2025) A study concluding that the weed killer glyphosate did not cause cancer was retracted last week after it was revealed in lawsuit documents that the authors did not disclose their relationship with Monsanto/Bayer. The editor-and-chief, Martin van den Berg, PhD of Regulatory Toxicology and Pharmacology, which published the article 25 years ago, wrote in the journal, “Concerns were raised regarding the authorship of this paper, validity of the research findings in the context of misrepresentation of the contributions by the authors and the study sponsor and potential conflicts of interest of the authors.”  The study, titled “Safety Evaluation and Risk Assessment of the Herbicide Roundup and Its Active Ingredient, Glyphosate, for Humans” and coauthored by three researchers in New York, The Netherlands, and Canada, was referred to as a “Landmark glyphosate safety study” in a recent article by U.S. Right to Know.   While this retraction not only sheds light on Monsanto’s influence through ghostwriting, it adds to the wide body of evidence regarding the regulatory deficiencies currently in place. The revelation is a reminder of related incidents in which Monsanto (Bayer) and other companies have wielded excessive influence at the U.S. Environmental Protection Agency (EPA), undermining the integrity of the science needed to inform the regulatory decisions that safeguard health and the environment. (See Daily News Corruption Problems Persist at EPA.)  EPA Deficiencies  In addition to the initial registration process, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires that EPA conduct a registration review of all pesticide […]

(Beyond Pesticides, December 5, 2025) A study published this month in Environmental Pollution analyzes the role of neonicotinoid insecticide exposure on bird populations, finding a significant negative effect of imidacloprid use on insectivorous bird abundance. In comparing the effects of the insecticide imidacloprid on bird abundance in France before and after the 2018 ban, the researchers show a weak recovery of bird populations after 2018. The persistent nature of imidacloprid, however, as well as the continued use of other petrochemical pesticides that have adverse effects on bird species, continues to impact populations of all types of birds and other wildlife, leading to cascading impacts on biodiversity.    “Our study shows that imidacloprid is a major covariate of the abundance of birds, in addition to other pesticides that are also negatively related to bird populations, and that these effects are not uniform across species,” the authors report. They continue in saying that the relationship between neonicotinoids and bird abundance varied across bird diets, as “the abundance of insectivorous birds was consistently lower under increasing pesticide use, in particular imidacloprid.” Background As shared in the study and on Beyond Pesticides’ Birds page, bird species can be exposed to pesticides directly through ingestion […]

(Beyond Pesticides, November 20, 2025) Recent scientific literature finds heightened toxicity associated with pesticide metabolites, the transformation/breakdown products of the parent compounds, that threaten the health of the soil, wildlife, and humans. This research stresses the importance of the U.S. Environmental Protection Agency (EPA) evaluating metabolites, which is currently insufficiently included in regulatory processes. In a literature review in Global Change Biology, the researchers point out multiple areas in which regulations fail to address key criteria, including metabolites, saying: “Pesticide risk assessments currently rely on surrogate species and focus primarily on acute lethality metrics, failing to capture the broader impacts on non-target organisms and thus biodiversity. Under the directives of regulatory agencies worldwide, this traditional approach overlooks the complex interactions between multiple stressors, including climate change, land-use shifts, and pesticide transformation products. Pesticide risk assessments must therefore undergo a paradigm shift to account for these complex interactions, which disproportionately affect insect pollinators, other non-target species, and biodiversity at large.” A metabolite is a breakdown product that forms when a pesticide is used in the environment and mixes with air, water, soil, or living organisms. All metabolites fall under the category of transformation products, which is the broader term for any […]

(Beyond Pesticides, November 19, 2025) In the book, Biological Control Systems and Climate Change, published this month, Danilo Russo, PhD—a speaker during the first session of our 42nd National Forum, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature—and other researchers add to the existing literature on the climate change threat to ecosystem services. Dr. Russo’s chapter, entitled “Impact of Climate Change on Bats Involved in Biological Control,” explains one of the lost benefits of ecological balance attributable to the climate crisis. As explained in the book: “In conservation biological control, habitats surrounding and within crops are managed to favour an increase in natural enemy populations while suppressing pest populations. These agroecological systems can be complex, and are affected by climate change.” The ability of climate change to influence the effectiveness of biological control systems is explored, showing the “effects on the large diversity of macro- and microorganisms involved in biocontrol, and the possible increase or decrease in pest outbreaks following changes in characteristics (morphology, physiology, behaviour….), distribution or phenology.” Dr. Russo is a full professor of ecology at the University of Naples Federico II, an international leader in bat research, and coauthor of A Natural History […]

(Beyond Pesticides, November 17, 2025) Beyond Pesticides ramped up its campaign to transition parks, playing fields, and schoolyards to organic land management after the release of a study showing synergistic effects of glyphosate (Roundup) and urea fertilizers on earthworms and soil health. The organization’s network is asking Mayors nationwide to lead the transition, pointing to the inadequacy of the current system of regulating pesticides based on risk assessments of individual chemicals or individual chemical families. Chemicals interact, causing increased impacts on human, ecological health, and biodiversity. Moreover, humans, other species, and the biosphere rarely experience exposure to single chemicals or chemical families; exposure to multiple chemicals is the rule, not the exception.   Synergistic effects associated with the use of the weedkiller glyphosate have been implicated in several studies showing magnified adverse impact in soil organisms and in mixture with other chemicals:  The extensive use of glyphosate is linked to effects on nontarget soil organisms, with the risks to soil ecosystems widely studied. (See here, here, here, here, and here.)   One study shows that frequent application in tropical systems of glyphosate “reduced soil macroarthropod richness by 21% and altered community composition.   “A recent global risk assessment of glyphosate further estimated that 67−93% of soils pose high risks to Collembola [springtails] and 43−67% pose medium to high risks to […]

(Beyond Pesticides, November 11, 2025) A study published in Cardiovascular Toxicology (July 2025) finds significant associations between Gulf War deployment-related toxic chemical exposure hazards and various adverse health outcomes, including heightened risk of atherosclerotic cardiovascular diseases (ASCVDs), such as “heart attack, coronary heart disease, stroke, transient ischemic attack, and peripheral vascular disease.” While there were no significant associations found directly between pesticide products and these adverse health effects, researchers attribute this to limited sample sizes and wide confidence intervals as part of the study methodology. Further research is necessary to build on this study, given the preponderance of scientific evidence linking pesticide exposure to heightened health risks to the cardiovascular system. On the issue of statistical significance, the authors state the following: “There may be difficulty [for survey respondents] remembering the[ir] military exposure history since the survey was completed nearly 25 years after the Gulf War.” While it is difficult to pinpoint pesticide exposure as a cause of illness among the toxic mixtures to which service members are exposed, there has been recognition by the Veterans Administration (VA) of diseases that are directly related to military service. Beyond Pesticides previously reported that the VA has established 20 burn pit and […]

(Beyond Pesticides, November 10, 2025) With a small but growing organic beer market, Beyond Pesticides is urging breweries to align with ecological farming practices and to seek out organic sources for their ingredients. In a June 2025 release, the marketing research firm Data Bridge reports that, “The global organic beer market size was valued at USD 7.24 billion in 2024 and is expected to reach USD 11.90 billion by 2032, at a CAGR [Compound Annual Growth Rate] of 6.4% during the forecast period.” The company attributes the growth to “health-conscious and environmentally-aware consumers” and finds “rising consumer preference for organic and clean-label beverages,” with consumers “actively seeking beer options made with organic hops, malt, and natural ingredients, free from synthetic pesticides or GMOs  [genetically modified organisms].” Harmful pesticides, including glyphosate, 2,4-D, and other toxic herbicides, insecticides, and fungicides, are used in the production of the ingredients of beer. Residues may remain in barley, oats, wheat, and hops used to make beer. Not only do the residues pose a risk to beer drinkers, but growing these crops nonorganically threatens farmworkers, waterways, wildlife, and pollinators.   More than 800 million pounds of pesticides are used each year in U.S. agriculture, with devastating impacts on soil life, pollinators, and ecosystem health. Harm to the soil microbiome and invertebrates like worms and beetles is magnified by synergistic interactions with chemical fertilizers, undermining the foundation of […]

(Beyond Pesticides, October 29, 2025) The latest research on bats and beavers, ecosystem services, and biodiversity adds to a wide body of science on the importance of a balanced ecosystem. In both the Bulletin of the National Research Centre and Journal of Animal Ecology, the researchers highlight the interconnectedness not only between wildlife species but to broader ecosystem functioning and human health implications. Researchers in the Journal article add to the growing body of science connecting an abundance of bat species in areas with established beaver dams, highlighting how interconnected wildlife is. The reporting on this recent research coincides with Beyond Pesticides’ 42nd National Forum, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature, scheduled for today, October 29. As the author of the article in the Bulletin of the National Research Centre, entitled “The complex web between environmental disruption, pesticide use, and human health: lessons from the bat crisis,” states: “The close relationship between environmental balance, biodiversity, and human health has long been a concern of science and public policy. Disruptions in ecosystems often trigger cascading effects that extend far beyond the original ecological imbalance, affecting agricultural practices, food security, and public health.” Bat Declines and […]

(Beyond Pesticides, October 27, 2025) With the confluence of science and law, the spotlight is on sewage sludge fertilizer and its contaminants, including per- and polyfluoroalkyl substances (PFAS). Sewage sludge (biosolids) is a byproduct of sewage treatment and is used as a source of organic matter for amending soil in nonorganic agriculture and landscaping. In light of a recent settlement in a lawsuit filed by Beyond Pesticides against ScottsMiracle-Gro, ongoing litigation against GreenTechnologies, LLC, and a major study identifying 414 contaminants of emerging concern (CECs), Beyond Pesticides’ network is calling on Governors and local officials to ban the use of biosolids on farms and parks, until there is adequate testing of toxic residues—which does not currently exist.   The lawsuits against producers of sewage sludge fertilizer cite test results showing PFAS residues in the companies’ products and numerous scientific studies on the adverse effects of PFAS to public health, wildlife, and pollinators. (See settlement statement recently reached with ScottsMiracle-Gro.)  A literature review published in Frontiers in Environmental Chemistry identifies CECs in soils, untreated and treated sewage sludge (biosolids), and dust, across 151 peer-reviewed studies released between 2018 and 2023—emphasizing the range of potential exposure pathways across various products, including classes of pesticides like neonicotinoid insecticides. […]

(Beyond Pesticides, October 22, 2025) The release of scientific studies on contaminants in sewage sludge (biosolids) used as fertilizers coincides with two lawsuits filed by Beyond Pesticides against ScottsMiracle-Gro and GreenTechnologies, LLC, in which the organization alleged that each defendant engaged in false and deceptive marketing and sale of fertilizer products that were marketed as environmentally friendly, despite containing per- and polyfluoroalkyl substances (“PFAS”). PFAS have been linked to cancer and other adverse effects. (See settlement statement recently reached with ScottsMiracle-Gro.) Biosolids are widely used in agricultural production and nonagricultural land management, including parks and playing fields, but  prohibited from use in certified organic agriculture under the Organic Foods Production Act. Two recent studies raise serious concerns about a range of contaminants in treated sewage sludge. While widely advanced as supplementing organic matter with macro- and micro-nutrients, treated sludge “harbor[s] a concentrated presence of contaminants that have adsorbed onto the soil post-wastewater treatment,” according to a literature review published in Frontiers in Environmental Chemistry. The researchers identify 414 contaminants of emerging concern (CECs) in soils, untreated and treated sewage sludge (biosolids), and dust, across 151 peer-reviewed studies released between 2018 and 2023—emphasizing the range of potential exposure pathways across various […]

(Beyond Pesticides, October 14, 2025) With escalating environmental, health, climate crises tied to petrochemical pesticides and fertilizers, Beyond Pesticides is calling the transition to organic land management a mandate, not a choice. Additionally, as a solution, organic agriculture has returned competitive yields with chemical-intensive farming and higher profitability. In this context, Beyond Pesticides and its network are supporting the Organic Science and Research Investment (OSRI) Act, S.1385 and H.R. 5703, to help grow the organic sector and are asking members of Congress to cosponsor the legislation. If passed, OSRI will make strategic investments into the U.S. Department of Agriculture’s (USDA) organic agriculture research, assisting farmers to meet the growing demand for organic products and keep organic dollars circulating in rural and regional economies. The House and Senate bills include the same legislative language.  As the health, biodiversity, and climate crises escalate, Beyond Pesticides views organic agriculture and nonagricultural land management as a social good, necessary to a sustainable future. Given the dismantling of many federal environmental programs and the weakening or undermining of pesticide regulation, the transition to the organic alternative has taken on increased importance, according to public health and environmental advocates. The true cost of conventional, petrochemical pesticide and fertilizer use is integral to any calculation of the […]

(Beyond Pesticides, October 9, 2025) The 42nd National Forum Series, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature—scheduled to begin on October 29, 2025, 1:00-3:30pm (Eastern time, US), will focus on aligning land management with nature in response to current chemical-intensive practices that pose a threat to health (see Pesticide-Induced Diseases Database), biodiversity, and climate. The virtual Forum is free to all participants. ➡️ Register here. The Call to the Forum, states: We are all affected by how land is managed, food is grown, and nature is protected. Different experiences and perspectives may bring us to care about health and the environment and the devastating adverse effects of pesticides and toxic substances. However, ensuring a livable future requires us to cultivate a collective concern about daily decisions on the management of our personal and community spaces, the practices used to grow the food we buy, and the care that we as a society give to complex and fragile interrelationships that sustain the natural world on which we depend.   The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature challenges participants—as concerned families, community residents, purchasers of products, advocates for policy, decision makers, and workers—to think […]

(Beyond Pesticides, October 8, 2025) A study, Pesticides detected in two urban areas have implications for local butterfly conservation, published in partnership with researchers at Xerces Society for Invertebrate Conservation, University of Binghamton (New York), and University of Nevada, reports widespread pesticide residues in the host plants of butterflies located in green spaces in the cities of Sacramento, California, and Albuquerque, New Mexico. Just 22 of the hundreds of collected samples had no detectable residues, with all other samples containing some combination of 47 compounds of the 94 tested pesticides in the plant tissue. Of the 47 compounds, 4 are neonicotinoid insecticides linked to adverse effects for bee and pollinator populations based on previous peer-reviewed research. The fungicide azoxystrobin and the insecticide chlorantraniliprole were detected at lethal/sublethal concentrations, according to the report authors. “Residential landscapes have high conservation potential for butterflies and other invertebrates,” says Aaron Anderson, co-lead author of the report and pesticide program specialist at Xerces Society for Invertebrate Conservation. He continues: “But, these findings show how pervasive pesticide contamination can be in towns and cities, and underscore that protecting wildlife in these areas includes addressing pesticides.” The report’s results underscore the pervasiveness of pesticide drift and dispel the myth […]

(Beyond Pesticides, October 2, 2025) This year marks an advancement of various state-level neonicotinoid laws and regulations, including in Maine, Vermont, and Connecticut—emphasizing surging public support for pesticide reforms. The Maine legislature passed, and Governor Janet Mills (D-ME) signed into law on July 22, 2025, LD 1323, which commissions the Board of Pesticide Control to study the impacts of neonicotinoids and neonicotinoid-treated seeds, which advocates hope will help advance future legislation to prohibit the use, distribution, and sale of neonicotinoid insecticide products. Meanwhile, after years of grassroots advocacy, the Connecticut legislature advanced, and Governor Ned Lamont (D-CT) signed SB 9 into law, which will partially restrict the nonagricultural use of neonicotinoids on turfgrass, starting in 2027. There was a more comprehensive effort that failed to move forward (HB 6916), which would have gone further by restricting or prohibiting the use of neonicotinoids on trees, shrubs, and treated seeds (see here for Beyond Pesticides comments). Maine and Connecticut join eleven other states (California, Nevada, New Jersey, Massachusetts, Maryland, Minnesota, New York, and Vermont) in taking steps to restrict or prohibit the use of neonicotinoids. (See Daily News here.) Whether it is a campaign to ban glyphosate, paraquat, chlorpyrifos, atrazine, or any […]

(Beyond Pesticides, September 29, 2025) With the theme “Our Home Outdoors,” the National Environmental Education Foundation (NEEF) launched National Public Lands Day this past Saturday—defining this year’s event as follows: “Our public lands are more than just places to visit—they are woven into the fabric of our everyday lives. From the trails we hike to the parks where we gather with family and friends, these spaces are our collective backyard, our shared front porch, our natural playground.” At the same time, people are asking their local governments whether they are using petrochemical pesticides and fertilizers on their parks and playing fields that are known to threaten the health of children, pets, wildlife, and the environment. Beyond Pesticides led a nationwide action to “Tell your local officials to make your parks organic.”  For those engaging with their local elected officials and parks departments, Beyond Pesticides, through its Parks for a Sustainable Future program, offers technical support to transition parks to organic land management through analysis of soil health, development of a plan to improve soil biology to cycle nutrients for healthy plants, training of staff to implement the organic plan, and ongoing consultation for plan adjustments when necessary. Organic systems focus […]

(Beyond Pesticides, September 26, 2025) National Public Lands Day on Saturday, September 27—first established in 1994 and held on the fourth Saturday of September—is organized by the National Environmental Education Foundation (NEEF) in partnership with the U.S. National Park Service and participating federal agencies. Events are planned at neighborhood, state, and national parks nationwide, and entrance to National Parks will be free for the day. Coinciding with National Organic Month, this year’s theme, ”Our Home Outdoors,” is explained by NEEF as: “Our public lands are more than just places to visit—they are woven into the fabric of our everyday lives. From the trails we hike to the parks where we gather with family and friends, these spaces are our collective backyard, our shared front porch, our natural playground.” Beyond Pesticides began its work on organic land management in national parks nearly a decade ago at National Historic Sites in Arkansas, Kansas, and Iowa. The program, now the Parks for a Sustainable Future program, partners with local communities in pursuit of a future where (1) public lands, from parks to playing fields, are managed without toxic pesticides, (2) children and pets are safe to run around on the grass, and (3) […]

(Beyond Pesticides, September 24, 2025) A novel study of chronic toxicity of the neonicotinoid insecticide thiamethoxam to honey bees (Apis mellifera), published in Insects, finds sublethal effects that threaten the survival of bee larvae and the health of bee colonies. “We evaluated the effects of thiamethoxam on the entire larval development cycle of reproductive bees and conducted a comparative analysis, demonstrating that thiamethoxam significantly alters ecdysone [a hormone that controls molting in insects] and juvenile hormone titers [hormones for insect growth] in both queen and drone larvae, impairing metamorphosis and reproductive development,” the authors state. Risk assessments and scientific literature focus primarily on honey bee workers, rarely including how pesticides can impact queen and drone bees that are necessary for stable colonies. In focusing on this data gap, the researchers reveal that the survival rate of bee larvae decreases gradually with increasing doses of thiamethoxam, adding to the wide body of science on pesticide-related threats to honey bee health. (See Beyond Pesticides’ What the Science Shows on Biodiversity page for more information, as well as Daily News coverage on risk assessments here, here, and here.) Honey bees provide crucial ecosystem services as pollinating insects and play a vital role in […]

(Beyond Pesticides, September 17, 2025) A study in Environmental Science & Technology finds additive effects of a synthetic pyrethroid insecticide (cypermethrin) and two fungicides (azoxystrobin and prochloraz) on biological control, biomass of major invertebrate trophic groups (position in food web), and soil ecosystem processes in arable systems (land suitable for growing crops). The study authors further highlight the failure of pesticide regulations to consider elaborate trophic interactions and pesticide mixtures, as well as additive and synergistic effects within their assessments, calling attention to the complexity of real-world exposures and the lack of research to fully understand the implications of chemical use for agricultural and land management purposes. “Arable systems have a high dependence on diverse natural biota to support pest control, soil bioturbation, and nutrient recycling,” the researchers write. These communities rely on a balance of organisms within various trophic levels in order to function and provide vital ecosystem services. Disruptions caused by environmental contaminants, such as pesticides to nontarget organisms, impact entire ecosystems and overall biodiversity. As the authors state, current risk assessments underestimate the real-world risks of petrochemical pesticides and synthetic fertilizers that, despite a wide body of science connecting exposure to deleterious health and environmental effects, are […]

(Beyond Pesticides, September 16, 2025) As reported in the Daily News on August 28, the U.S. Environmental Protection Agency (EPA) announced that it “will hold a public webinar [today], September 16, 2025, at 2:00 PM ET to provide information on the ecological runoff/erosion and spray drift mitigation measures that can be used to protect endangered species from pesticides.” This follows closely behind an earlier announcement of a newly released Pesticide App for Label Mitigations (PALM) mobile tool to assist in implementing these mitigation measures. Despite boasting that the PALM tool is a “one-stop shop” for farmers to use EPA’s mitigation menu, which the agency claims helps to protect nontarget species, environmental critics say that self-directed mitigation without a rigorous reporting and enforcement apparatus fails to meet the level of protection that is necessary under the Endangered Species Act (ESA). As Beyond Pesticides has often reported, mitigation measures are not enforced through recordkeeping, inspections, and certification, and require no accountability from farmers and pesticide applicators. At the same time, EPA assumes compliance with mitigation measures as the basis for meeting statutory standards of reasonable risk from harmful chemicals, despite documented health and environmental harm. As a Daily News article earlier this […]

(Beyond Pesticides, September 15, 2025) With residues of the widely used weed killer glyphosate (Roundupᵀᴹ) in the food supply long documented, scientific attention has turned to the synergistic effects of the weedkiller— a magnified effect greater than the individual chemical effects added together. The authors of an article in World’s Poultry Science Journal write, “The synergistic toxic effects of commercial glyphosate formulations and their bioaccumulation in animal tissues are often overlooked in current safety assessments.” Following up on a previous action, Beyond Pesticides is telling Congress and the U.S. Environmental Protection Agency (EPA) that the agency must consider the effects of pesticides in the context in which they are used and promote the organic alternative.  Glyphosate residues in animal feed, as well as in water and through other exposure routes from food generally and residential areas, pose risks to both animal and human health, as these residues can bioaccumulate. As previously examined by Beyond Pesticides, the effects of pesticides are not limited to the crops to which they are applied. Synergistic effects of multiple chemical exposures are the rule, rather than the exception.   With poultry, the herbicide enters the production system through residues in genetically engineered feed. An earlier article in Scientific Reports concludes that glyphosate’s […]

(Beyond Pesticides, September 10, 2025) Published earlier this year, a review of over 1,700 studies in Nature Communications finds pesticides affect a diverse range of nontarget organisms and contribute to global biodiversity loss. The authors* reveal “negative responses of the growth, reproduction, behaviour and other physiological biomarkers within terrestrial and aquatic systems” for nontarget plants, animals, and microorganisms. “To our knowledge, there has been no systematic and overarching synthesis of how different types of pesticides affect the diversity of multiple non-target eukaryotic and prokaryotic organisms across all trophic levels,” the researchers write. They continue, “Furthermore, current syntheses have not considered how the impacts of pesticides differ globally across climatic zones or for major mechanisms of exposure, such as those acting in aquatic or terrestrial environments.” In particular, pesticide regulatory risk assessments analyze a limited range of model species, including rats, zebrafish, clawed frogs, honeybees, and earthworms, among others. As such, they are unlikely to capture the variety of responses to pesticide exposure seen across the diversity of species and communities found in both managed and natural systems,” the authors state. *Authors include Beyond Pesticides 2023 National Forum speaker Dave Goulson—see the Daily News on his keynote address here. Research Results […]

(Beyond Pesticides, September 8, 2025) Beyond Pesticides today called on Congress to require the U.S. Environmental Protection Agency (EPA) to incorporate real world science into its evaluation of pesticide safety calculations by recognizing that daily exposure involves multiple chemicals and synergistic interactions— a magnified effect greater than the individual chemical effects added together. The organization cites numerous scientific studies that call public attention to this issue; that a realistic assessment of the human and environmental harm potentially caused by pesticides cannot be evaluated based on single-chemical, single-species tests. Given the numerous complexities associated with this type of assessment, the group points to organic land management in agriculture and residential areas as a more cost-effective approach, sending this message to Congress: EPA must consider the effects of pesticides in the context in which they are used and with reference to the organic alternative. A recent study, covered by Beyond Pesticides in its Daily News, found that the presence of Varroa mites in combination with the neonicotinoid insecticide imidacloprid increases the risk of bee mortality and disrupts the larval gut microbiome. The study found synergy (a greater combined effect) between Varroa destructor, a parasitic mite that attacks and feeds on honey bees, and imidacloprid. The findings were published last […]
