(Beyond Pesticides, July 2-3, 2026) Our call on Independence Day for freedom from the toxic chemicals that tear apart our families and the ecosystems on which all life depends is proclaimed this July 4th with even greater urgency than last year. The decision by the U.S. Supreme Court last week in Monsanto v. Durnell—releasing Monsanto-Bayer of liability for failing to warn those harmed by pesticides—enshrines in our daily lives the power of chemical companies to poison and contaminate with impunity. What did the majority of the Supreme Court justices say in supporting the right of chemical companies to poison without warning? The justices opined that, if they were to support the original plaintiff diagnosed with non-Hodgkin lymphoma after using the Monsanto weedkiller RoundupTM without any cancer warning on the label, it would “expose manufacturers to potentially massive tort liability for doing what EPA required.” And that is exactly what happened when juries across the U.S. issued verdicts against Monsanto amounting to billions of dollars since 2018. The justices could not let that stand. Instead, the justices, in putting the freedom of chemical companies to poison for profit without notification above the rights of people to be warned, have codified a […]

(Beyond Pesticides, June 29, 2026) With the release of the Republican Farm Bill in the U.S. Senate on June 23 and passage of a bill with nearly identical provisions in the U.S. House of Representatives on April 30, Beyond Pesticides and allies are calling on U.S. Senators to reject the GOP Farm Bill as drafted, citing an undermining of public and environmental health. In addition to severe criticism of the bill language, the Chair of the Senate Agriculture, Nutrition, and Forestry Committee, Senator John Boozman (R-AR), is being criticized by farm, farmworker, health, and food security groups for characterizing the House bill as “bipartisan” and a “significant achievement” because both the House and Senate bills were drafted without input from Democrats.  U.S. Senator Cory Booker (D-NJ), a Senate Agriculture Committee member, said: “The draft Farm Bill released today by Senate Republicans fails to meet this moment of crisis that American farmers and families are facing. . . [I]nstead, it goes backward, by undermining USDA support for regenerative agriculture and creating loopholes for pesticides to avoid safety oversight. I will not vote for a Farm Bill that leaves small farmers without a functioning safety net, does not make healthy, clean food more […]

(Beyond Pesticides, June 25, 2026) In a study comparing pesticide active ingredients (isolated single chemicals) with full pesticide product formulations containing added ingredients (the packaged products that can contain carriers, sticking agents, emulsifiers, etc.), researchers find the full formulation to be generally more toxic. The research evaluates acute and chronic exposures of four mosquito adulticide active ingredients (AIs), three product formulations, and one biological larvicide pesticide formulation containing Bacillus thuringiensis israelensis (Bti) on honey bee larvae in vitro and finds that three of the four exceed levels of concern (LOCs) set by the U.S. Environmental Protection Agency (EPA). EPA publishes Guidance for Assessing Pesticide Risks to Bees in which it identifies levels of harm. The scientists who conducted the study, published in Environmental Challenges, are based at the University of Florida and Auburn University. This study references Bti (Vectobac12AS) as the least toxic product, since the acute LD50 (lethal dose that kills 50% of the test population) is well below EPA-set LOCs. However, the study only focused on whether Bti harms honey bees. In contrast, there are some indications of its potential adverse effects on other beneficial insects, moths, and butterflies (see fact sheet here) and aquatic life, including studies […]

(Beyond Pesticides, June 24, 2026) Yesterday, Senator Boozman (R-AK), chair of the Senate Agriculture, Forestry, and Nutrition Committee, released the Senate GOP Farm Bill, the Agricultural Act of 2026, with provisions that undermine public and environmental health, according to farm, farmworker, and environmental advocates. Rather than investing sufficiently in organic agriculture and supporting farmers’ transition to nontoxic practices—in response to health, biodiversity, and climate crises, as well as the high cost of synthetic fertilizers—the bill reduces oversight of organic production by loosening inspection and certification requirements. “The bill, drafted without input from Senate Democrats, redefines underlying statutory standards, increasing dependency on petrochemical pesticides and fertilizers in agriculture at a time when we urgently need to shift to sustainable and cost-effective agricultural and land management practices,” said Jay Feldman, executive director of Beyond Pesticides, a national public interest group representing farmers, consumers, and environmentalists. “We are facing health and environmental crises, demanding leadership—not exhibited in this Republican Farm Bill—that ensures a livable future,” Mr. Feldman said. The text is largely the same as the version passed by the U.S. House of Representatives in April, the Farm, Food and National Security Act of 2026 (H.R. 7567). The House vote made history when 73 […]

Image: Art of Life Page submission from Jesse Yow, “Honeybee Pollinating Citrus Blossom.” (Beyond Pesticides, June 22, 2026) National Pollinator Week, June 22-26, 2026, celebrates all pollinators and the ecosystem services they provide. With a theme of “Life on a Leaf… From Bloom to Buzz! An Organic Solution for Plants and Pollinators” and in recognition of the importance of pollinators and biodiversity to a healthy environment and healthy people, Beyond Pesticides announces a week of activities and actions!  Pollinators—bees, butterflies, birds, bats, and other organisms—make a critical contribution to plant health, crop productivity, and the preservation of natural resources, but their existence is threatened by pesticide-contaminated habitats! Throughout the week, we will suggest actions that you can take to promote the health of pollinators.   The first step is providing a safe place for pollinators to live, eat, reproduce, and take refuge from predators and adverse weather, which can include establishing pollinator-friendly plants as both habitats and food sources.  Monday—Juneteenth and Environmental Justice  Dr. Martin Luther King Jr. famously stated, “All life is interrelated.” Justice for all people converges with the protection of biodiversity, health, and climate. If we are not protecting the most vulnerable in society, we ultimately adversely affect the entire society because all people are intricately linked through the web of life. By […]

(Beyond Pesticides, June 11, 2026) A study of honey bee colonies in Florida and California, published in Environmental Toxicology and Pharmacology, finds elevated mortality from pesticide residues, including those that have been documented to threaten pollinators. As the authors describe, “While bees die from multiple, often interacting, stressors, here we show single contributors at levels capable of causing acute harm.” The presence of miticides, fungicides, herbicides, and insecticides within the bee colonies, including in the bodies of dying bees, further highlights pesticides as drivers of bee declines. By sampling both dying bees and in-house bees for chemical residues, the researchers are able to compare symptomatic colonies and control colonies. The authors note, “Our findings differ from previous screenings, which cast a broad net, screening agrochemicals in colonies nationwide, and not necessarily from impacted operations.” This study, however, shows the presence of specific pesticide residues in commercially managed colonies after die-off incidences. The neonicotinoid insecticide imidacloprid, in particular, is widely detected and found in high levels, with the researchers identifying the compound as the largest contributor to bee death. Background Scientific literature linking pesticides, including neonicotinoids, to adverse impacts on pollinators continues to mount, as do the devasting population declines of […]

(Beyond Pesticides, June 4, 2026) In a study published in Perspectives in Ecology and Conservation, researchers in Brazil find that organic farming coupled with agroecological conservation practices “promote[s] biodiversity in agricultural landscapes.” The proxy for biodiversity in this study is anurans, a type of frog or toad native to the Brazilian Pampa—a section of the South American Pampas grasslands, a globally underrecognized biodiversity hotspot. According to a scientific report reviewed by Mongabay in 2024, “nearly a third of the Brazilian portion…has been lost since 1985, largely to agricultural expansion and forestry plantations.” In the U.S. context, public health and environmental advocates continue to call for the transition to organic land management as a solution that validates the ecosystem services that biodiversity-forward agricultural systems can provide under values-aligned stewardship. Methodology and Main Findings The authors in this study, researchers at the Universidade Federal do Rio Grande do Sul, surveyed 26 artificial ponds across 16 family farms with different land management systems—9 organic farms and 7 conventional farms—located in the Serra do Sudeste region of the Brazilian portion of the Pampa grasslands. All farms were sampled three times during the 2023 to 2024 breeding seasons (twice in the October to November 2023 […]

(Beyond Pesticides, May 29, 2026) In a new study published in Environmental Pollution, researchers detected 15 currently used pesticides (CUPs)—including 10 pesticide compounds detected but not applied within the study’s managed fields— in the pollen of beehives in an environment meant to reflect a typical honey bee foraging range. The detection of pesticides that were not directly applied within the study’s target radius demonstrates the pervasiveness of pesticide drift into soils, streams, and bodies. In this context, public health and environmental advocates continue to call for a wholesale transition to organic land management. The findings are particularly concerning given the toxicity hazards to honey bees associated with pesticide exposure in this study and bolstered by other studies, resulting in documented threats to their health—as reviewed in this Daily News below. Methodology and Background Researchers at the University of Bern and Agroscope, the Swiss government’s agricultural research arm, conducted this research with agricultural land-use data for 2023 and 2024 from the Zurich (provincial/Canton) government. The study area was defined as a 2-kilometer radius around the hive placement site, with 4 active hives over the course of a two-year period (April 10, 2023, through May 3, 2024). The land use within the […]

(Beyond Pesticides, May 28, 2026) Researchers from France and Germany, as published in Agriculture, Ecosystems & Environment, find that declines in bird populations are strongly linked to their diets, with insectivorous birds experiencing the greatest impacts. “Overall, our results emphasize the strong association between insecticide use and insectivorous bird declines,” the authors state. They continue: “We found a consistent negative association between insecticide use and population trends of insectivorous birds, the most abundant group, regardless of migration strategy. This pattern suggests indirect effects linked to the depletion of insects as a food source.” In analyzing bird population trends in France over 15 years and comparing bird responses across diets and pesticide types, this study highlights the negative association between insect population declines and insectivorous bird population declines that are linked to agricultural intensification. Study Background The impacts of pesticides on birds, as described on Beyond Pesticides’ resource page, can occur through various routes of exposure. Birds can be exposed to pesticides directly through ingestion of seeds that have been treated with pesticides, or indirectly through consumption of small insects and other animals that have ingested the pesticides themselves, leading to secondary poisonings of the birds. They can also be indirectly […]

(Beyond Pesticides, May 20, 2026) A study of two pollinator species, honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata), finds oxidative stress (OX)— an imbalance between antioxidant defenses and excess reactive oxygen molecules (species), or ROS—resulting from exposure to non-living (abiotic) stressors, such as synthetic chemicals, leading to cell damage. Regulatory bodies, including the U.S. Environmental Protection Agency (EPA), do not routinely evaluate oxidative stress as a standalone or required endpoint in standard pesticide registration protocols. In comparing pollinator responses to different pesticides and pest control management practices, the lowest levels of OX are exhibited in organically managed systems, as described in the research published in Physiological Entomology. Quantifying the oxidative stress levels in bees and their larval stages from three landscapes (conventional, organic, and roadside) shows that minimum exposure to agrochemicals and high traffic-related pollutants results in the lowest levels of OX. “Overall, these findings show that variation in pesticide residue profiles across landscapes is associated with different OX responses in bees,” the authors state. “Given the essential ecosystem services provided by bees, our findings underscore the urgent need for landscape-level strategies to reduce pollinator exposure to chemical stressors.” Background Oxidative stress occurs when there is a […]

(Beyond Pesticides, May 15, 2026) As water bodies continue to be contaminated by pesticides and fertilizers used in chemical-intensive agriculture, international researchers find increasing threats to both aquatic and terrestrial food webs with insect transmission of pesticide residues from water to land. Published in Environmental Pollution, the study authors analyze insect species with complex life cycles “with an aquatic phase as larvae and a terrestrial phase as winged adults when they serve as prey for many aerial insectivores, such as bats and birds.” As the researchers explain, these insects act as vectors, transferring pesticides from water bodies into terrestrial food webs. As a result of studying feces from birds and bats that prey on these insects, the authors find residues of 16 current-use pesticides, two legacy compounds, and six metabolites (breakdown products). The study results illustrate that pesticide contamination occurs through the ingestion of contaminated prey from aquatic systems, as all of the substances recovered in the fecal samples are detected in the water bodies within the study region. The transfer of pesticides from emerging insects to other species in the food web further threatens biodiversity and ecosystem functioning. In summary, the authors state, “Our study is among the first […]

(Beyond Pesticides, May 14, 2026) In a new report by Friends of the Earth, federal organic standards as defined by the Organic Foods Production Act (OFPA) are identified as a bedrock “Threshold Program” with high minimum standards that combine three core features—synthetic pesticide and fertilizer prohibitions, soil health requirements, and third-party verification and enforcement systems. In other words, the review of thirteen regenerative and regenerative organic labels and enforcement systems must be built on enforceable standards. This criterion is foundational to the growth of the U.S. organic sector to over $76.6 billion in domestic sales in 2025, expanding at a pace nearly twice the rate of growth (6.8 percent) compared to the national agricultural sector more broadly (3.4 percent). Main Findings The report focuses on the principles of 13 different regenerative labeling and certification systems on the market, including a comparison of federal organic standards and the U.S. National Organic Standards Board (NOSB). The main findings and features of the report include: “Truly regenerative agriculture must phase out dependency on agrochemicals that undermine the very ecological functions on which resilience depends.” The various “regenerative” agriculture labels currently on the market are significantly varied in terms of pesticide and fertilizer restrictions […]

(Beyond Pesticides, May 11, 2026) As studies stack up on adverse synergistic effects of chemical mixtures, serious deficiencies in the regulatory review of pesticides have come into sharp focus. As the hazards are shown to escalate and the regulatory review process is shown to fall short, public health advocates are telling Congress, the U.S. Environmental Protection Agency, and the Department of Health and Human Services that they must consider the effects of pesticides in the context in which they are used and with reference to the organic alternative.  A recent study in Toxics reviewed the current literature on pesticides, microplastics, or metal exposure in combination with per- and polyfluoroalkyl substances (PFAS) on aquatic vertebrates and invertebrates, finding that PFAS can modify, including intensify, the toxicity of co-occurring pollutants.   A commentary in Frontiers in Toxicology, by  Maricel Maffini, PhD, and Laura Vandenberg, PhD,  notes, “Current approaches also rely on the assumption that testing chemicals one at a time is appropriate to understand how chemicals act under real-world conditions. Numerous mixture studies, including ones that demonstrated cumulative effects, have disproven this assumption.”   As noted by the naturalist, writer, and conservationist John Muir, known as the “Father of the National Parks,” and those before and after him, including the English poet John Donne, […]

(Beyond Pesticides, May 6, 2026) Adding to the wide body of science highlighting the adverse effects of pesticides on pollinators, as extensively documented in Daily News and What the Science Shows on Biodiversity, a study published in Insects finds threats to Italian honey bees (Apis mellifera ligustica) following exposure to insecticides with contrasting toxicity levels. Both the high toxicity and low toxicity compounds impact honey bee gut bacteria and gut microbial composition, showing how even “reduced risk” insecticides can have sublethal effects and jeopardize pollinator health. As the authors point out, “Honey bees depend on a small but highly specialized community of gut bacteria that help them digest food, resist infections, and cope with environmental stress.” Because of this, chemicals that disrupt the honey bee gut microbiome can threaten their survival. In the current study, the researchers analyze two compounds to determine adverse impacts on honey bees’ gut microbiota: emamectin benzoate-lufenuron (EB-LFR), an avermectin insecticide with high toxicity, and RH-5849 (1,2-dibenzoyl-1-tert-butylhydrazine), a non-steroidal ecdysone agonist (mimicking the action of the insect molting hormone) and insect growth regulator with reported lower toxicity. The results reveal that both toxicity levels can harm gut microbial composition, with EB-LFR “associated with observed reductions in […]

(Beyond Pesticides, April 30, 2026) On April 27, 2026, advocates—including Beyond Pesticides—from across the political spectrum came together in front of the U.S. Supreme Court to speak out against the chemical industry campaign, led by Bayer/Monsanto, the Trump administration, and Republican lawmakers, to shield chemical manufacturers from liability for failing to warn people who have been harmed by their pesticides. Their multi-pronged strategy targets the U.S. Supreme Court, U.S. Congress, and state legislatures. The question of the public’s right to sue chemical manufacturers that do not warn of product hazards was heard before the Supreme Court, as Monsanto argued that people who have been diagnosed with cancer after using the weed killer glyphosate should be prohibited from suing the company for failing to warn on the product label. The chemical manufacturer argued in Monsanto v. Durnell that federal registration of a pesticide preempts legal rights afforded to people under state law under U.S. federalism. The chemical industry is asking the U.S. Supreme Court to reverse decades of jurisprudence and shield manufacturers from liability associated with those who are harmed but not warned about pesticide adverse effects like cancer, neurological or immunological conditions, reproductive dysfunction, and other chronic illnesses. Highlighted Quotes […]

(Beyond Pesticides, April 24, 2026) In a review of scientific literature documenting pesticide contamination in the atmosphere, international researchers find human and ecosystem exposure even in remote and distant areas. As published in the Journal of Hazardous Materials, the authors state: “Atmospheric transport of pesticides is a globally significant yet widely underestimated driver of human and ecological exposure, with contamination documented far beyond treated fields. This review provides a novel integrated synthesis, bridging emission pathways, atmospheric transformation processes, monitoring evidence, model limitations, and regulatory gaps to deliver a comprehensive understanding of the fate and impacts of pesticides in the atmosphere.” In analyzing the current knowledge on pesticide emissions, through both drift and volatilization (process where a solid or liquid converts into a gas or vapor), the researchers highlight “the widespread detection of both current-use and banned pesticides in environmental matrices far from their application,” along with the resulting implications for human health and environmental health. As the current risk assessment framework “fails to adequately address the perturbations caused by the atmospheric transport of pesticides,” the urgent need to transition away from chemical-intensive practices grows stronger. Background While this review highlights regulatory gaps in the European Union (EU), the cited scientific […]

(Beyond Pesticides, April 23, 2026) “Fully organic growers face fewer agronomic challenges as compared to mixed growers,” according to a recent analysis published in Agricultural Systems by researchers at the University of California. The authors cite a slowing growth rate for organic certification and new organic farms, despite an increase in consumer demand. A 2025 Organic Trade Association (OTA) report shows organic market product sales at $76.6 billion with an annual growth rate of 6.8 percent—double that of the non-organic marketplace (3.4 percent). On the eve of the 2026 National Organic Standards Board (NOSB) spring meeting to review organic standards and update the National List of Allowed and Prohibited Substances, public health and environmental advocates, and members of the broader regenerative organic movement, will gather. The Board convenes twice a year to vote on key issues that are under review and have been subject to public hearings and comments, intended to ensure organic integrity and expansion. Methodology and Results The researchers combined quantitative and qualitative data from a survey and a set of interviews, respectively, with organic farmers in the state of California. For the survey, 426 certified organic farmers in California responded to questions asking “growers to report on […]

(Beyond Pesticides, April 20, 2026) Earth Day, this week on Wednesday, April 22, is a day of education and action. Earth Day embodies the power of people in their communities engaging to advance changes in policies and practices that meet the environmental and public health challenges of the day. This year, 2026, may be a turning point in which public outrage about the failure of the current political leadership in Congress and in the Trump administration to address the existential health, biodiversity, and climate crises is deemed politically unacceptable. Animating public concern are elected officials who call the climate crisis a hoax and dismiss the health and environmental threat associated with the weed killer glyphosate (Roundup)—as representative of the deregulation of pesticides associated with cancer and other deadly diseases. The words of the chair of the U.S. House of Representatives Subcommittee of Health and the Environment, Representative Paul Rogers (D-FL), express in the importance of grassroots action that elevated Earth Day. In a piece in the EPA Journal, Rep. Rogers wrote the following: “Historians of the environmental movement are likely to peg Earth Day 1970 as a key turning point in the American public’s consciousness about environmental problems. I believe […]

(Beyond Pesticides, April 16, 2026) A study of organic tomato agroecosystems with managed and wild bees, published in Apidologie, affirms the importance of protecting natural systems to support organisms that contribute to crop productivity. The study finds that the strategy of introducing social bees, even those native to other nearby areas, to enhance pollination in open-field conditions provides no direct benefits to the crops that are better served by wild bees. In evaluating the addition of Melipona quadrifasciata stingless bees, not native to the study site, for assisted pollination of tomato plants cultivated in open organic fields, the researchers note that “the presence of M. quadrifasciata hives did not influence fruit quality, indicating that wild bees primarily drove pollination benefits.” This research, in assessing both wild and managed bees in organic tomato agroecosystems, supports previous scientific literature showing that promoting naturally occurring pollinators is the most sustainable and cost-effective strategy for ensuring pollination services. “This finding underscores the importance of conserving and promoting wild pollinator diversity in organic agroecosystems, as they play a critical role in sustaining pollination services,” the researchers affirm. They also say, “By offering a diverse range of floral shapes, colours, traits, and sizes, non-crop plants support […]

(Beyond Pesticides, April 13, 2026) There are numerous provisions—a package of provisions—in the U.S. House of Representatives Agriculture Committee Farm Bill, voted out on March 5, that seriously undermine protections of health and the environment from pesticides, according to public health and environmental advocates. In response, Beyond Pesticides and allies are calling on U.S. Representatives and Senators to reject the Farm Bill as passed out of the House Agriculture Committee and, instead, pass a one-year extension of current law to protect health and the environment. The Committee Farm Bill contains provisions that advocates and members of Congress call “poison pills” because any one of them is so far-reaching that they make the entire measure unacceptable. The package of amendments covers critical areas of protection that have been established over decades of Congressional action. While groups have called for major reforms, Beyond Pesticides, in an action recently released,  says, “Existing pesticide law forms the foundation on which improvements should be made, not backsliding to give the chemical industry free rein.” At stake, according to the group, are core safeguards that are seen as critical to the health of farmers, consumers and the environment—judicial review of chemical manufacturers’ failure to warn about pesticide […]

(Beyond Pesticides, April 7, 2026) In the International Journal of Molecular Sciences, a study of gestational (during pregnancy) exposure to the neonicotinoid insecticide thiacloprid shows epigenetic effects (alterations in genes without altering underlying DNA) within prostate tissues. To analyze the role of gene expression in subsequent generations after initial thiacloprid exposure, the authors exposed pregnant outbred Swiss mice to the insecticide in order to assess the offspring for multiple generations. As a result, the researchers from the Université de Rennes in France state, “Our study revealed that exposure to thiacloprid induces [cell] proliferation and is associated with epigenetic alterations in the sperm of genes important for prostate development.” Increased cell proliferation in the prostate can cause the development of conditions such as benign prostatic hyperplasia (BPH) and prostatic intraepithelial neoplasia (PIN), and lead to prostate cancer. The study also finds elevated levels of specific biomarkers within the prostates of both the first and third generations, including phosphorylated histone H3, a marker crucial for cell division. Hox gene expression in both generations was also impacted, which plays a role in prostate development, based on the altered DNA methylation (abnormal changes) in the sperm of the analyzed mice. “In this study, we […]

(Beyond Pesticides, March 31, 2026) A statement decrying chemical company secrecy was released today by over 200 grassroots, health, farm, farmworker, environmental, and consumer groups, socially responsible corporations, over 340 citizens from 46 states, and international partners. The statement, released before the U.S. Supreme Court tomorrow reaches the final deadline for submission of amicus briefs in a case in which Bayer/Monsanto argues, with support of the Trump administration, that it should not be required to disclose on its product labels the potential hazards of its pesticide products. Oral arguments in the case will be heard on April 27, with a decision anticipated in June. Decades of law have upheld the legal argument that chemical companies are liable for their failure to warn users of their pesticides about the harm that they could cause. Bayer/Monsanto is attempting to reverse years of case law and billions of dollars in jury verdicts and future cases in which the company has been held liable for causing cancer but not warning product users. See statement, Stop Chemical Company Secrecy of Pesticide Product Hazards. Chemical Industry State Campaign The chemical industry last year launched a multi-pronged campaign to establish immunity from litigation by those who have […]

(Beyond Pesticides, March 24, 2026) Published in Environmental Pollution, study results in the floriculture region of Ecuador find detections of neonicotinoid insecticides (NNI) and the herbicide atrazine in drinking and irrigation water. The biomonitoring data reported in an earlier journal article in the same region found a total of 23 compounds used as herbicides, insecticides, and fungicides, their associated metabolites (breakdown products), which include organophosphates, pyrethroids, and neonicotinoids. (See Daily News here.) Researchers from the University of Iowa, University of California, San Diego State University, and Universidad de San Francisco in Quito, Ecuador, determined that 1 in 5 households (20.5%) have detectable levels of one or more neonicotinoids in drinking water samples surrounding floricultural agricultural operations. This builds on previous research underscoring the nontarget pesticidal effects in communities near agricultural operations where the chemicals drift through the air and move into soil and water. Methodology and Results The authors report that, “This study focused on household tap water in proximity to floricultural plantations and in the ESPINA [Secondary Exposures to Pesticides among Children and Adolescents] participants’ homes with a range of NNI and total pesticides in urinary metabolite samples of the children.” They continue: “Participant households in the water study were […]
