(Beyond Pesticides, April 28, 2026) In Chemical Research in Toxicology, researchers from the Universitat Rovira i Virgili in Catalonia, Spain highlight the threats to human and environmental health with “combined exposures to multiple chemical toxicants, including industrial chemicals, heavy metals, pesticides, endocrine-disrupting chemicals (EDCs), and per- and polyfluoroalkyl substances (PFAS).” As these compounds are encountered in mixtures in real-world settings, the resulting interaction can have additive or synergistic effects that risk assessments fail to adequately capture. As the authors point out: “This leads to a systematic underestimation of health risks, particularly for vulnerable populations. Despite robust evidence on mixture toxicity, major regulatory frameworks such as the U.S. Toxic Substances Control Act (TSCA) and the EU’s [European Union] REACH program continue to assess chemicals in isolation.” Importance and Background Environmental toxicants are ubiquitous throughout nature and within all organisms. In humans, these compounds can accumulate, referred to as ‘Body Burden’, which encompasses numerous chemicals such as pesticide mixtures. “Critically, organisms are rarely exposed to a single chemical in isolation,” the researchers note. “Rather, they continuously encounter complex mixtures of contaminants whose combined effects may differ substantially from those predicted by examining each substance individually.” As the authors explain, regulatory agencies underestimate […]

(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 […]

Riparian zones, recognized as biodiversity hotspots, “are increasingly subjected to various stressors, including chemical contaminants such as pesticides,” the authors state. As transportation of these compounds can occur not only through surface runoff but through flooding events, the frequency and duration of floods can greatly impact the cumulative effects of pesticides on soil health and organisms within ecosystems. In analyzing pesticide residues following simulated flooding within a controlled experiment, the researchers find: “[S]ix pesticides were detected exclusively in riparian root-zone soil following four repeated flooding events. Our findings indicate that both longer flood durations and repeated flooding events tend to increase […]

(Beyond Pesticides, April 17, 2026) A comparative analysis published in The Lancet Planetary Health highlights the pervasiveness of pesticide pollution in organic and non-organic farms in Latin America (Costa Rica) and Africa (Uganda). While pesticides were detected in nearly all participating farmers, there is a significant relationship between lower biomarker concentrations (often correlating with less contamination) in urine samples of organic farmers relative to non-organic farmers. The researchers also identified that older farmers held higher herbicide and insecticide concentrations. This research builds on the preponderance of scientific evidence and lived experiences of agricultural communities across the globe, including the U.S., which documents nontarget contamination of food systems through air, water, and soil. In this context, Beyond Pesticides continues to advocate for a transition to organic land management practices. Methodology and Results “We collected urine samples from 601 conventional and organic smallholder farmers in Zarcero County, Costa Rica, and Wakiso District, Uganda, on two occasions during the primary spraying season,” the authors write in introducing their methodology. The researchers tested urine samples of small-scale farmers in Costa Rica and Uganda for a mix of pesticides that include a fungicide, herbicide and insecticides—mancozeb (ETU), 2,4-D, glyphosate, pyrethroid metabolites (3-PBA, DCCA), diazinon (IMPy), […]

(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 14, 2026) A novel study mapping pesticide mixtures and cancer risk, published in Nature Health, “reveals a robust spatial association between environmental pesticide exposure risk and cancer incidence.” The team of international researchers incorporates pesticide risk modeling with Peruvian National Cancer Institute (INEN) registry data to map pesticide-induced cancer clusters in Peru, finding significant associations between pesticide mixtures and cases of carcinogenicity. The study analyzes 31 active ingredients to identify pesticide-associated cancer hotspots, none of which are classified as carcinogenic on their own by international standards. When combined as pesticide mixtures, as experienced in real-world environments, heightened risks and synergistic effects are noted. “Collectively, these findings strongly support a mechanistic [causal] link between pesticide exposure and cancer, challenging assumptions of human non-carcinogenicity derived from reductionist experimental models,” the authors state. “This study redefines the exposome [measure of all environmental, dietary, lifestyle, and social exposures of an individual] as a lineage-conditioned, mechanistically tractable framework and shows how complex pesticide mixtures can contribute to carcinogenic trajectories, with profound and far-reaching implications for global health policy and socio-ecological equity.” Background An extensive body of scientific literature connects individual pesticide active ingredients to a wide array of health and environmental effects […]

(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 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 […]

(Beyond Pesticides, March 19, 2026) A study of water contamination in Protected Areas (PAs) in Brazil, published in Science of The Total Environment, highlights the pervasiveness of pesticides. “Our objective was to evaluate the effectiveness of these PAs in mitigating pesticide contamination in watercourses and to investigate how land use patterns influence the presence of pesticide residues,” the authors state. “We found pesticide compounds in biofilms [mutually beneficial community of microorganisms] both inside and outside PAs’ streams, with no buffer effect of these protected lands against herbicides, insecticides and fungicides, contrary to our expectations.” In analyzing epilithic biofilms, which are communities of microorganisms that adhere to submerged rocks and surfaces in aquatic ecosystems, the researchers find residues of 14 pesticide compounds and one metabolite across the 19 sampling sites, threatening aquatic organisms and ecosystem functioning. The authors say, “[M]onitoring epilithic biofilms in PAs provides valuable information by detecting pesticide compounds that analysis of surface water and sediments might miss.” Through various routes, such as runoff to waterways, leaching into groundwater, and aerial drift, pesticides are ubiquitous in the environment, even in remote and protected areas. As the testing of the freshwater epilithic biofilms in this study reveals 15 pesticide residues […]

(Beyond Pesticides, March 4, 2026) In the International Journal of Epidemiology, researchers from France assess the risks of kidney cancer with a wide range of agricultural activities and tasks, finding that occupational exposure heightens kidney cancer risk. In studying participants from the French AGRIculture and CANcer cohort (AGRICAN) with incident kidney cancer, elevated risks of disease development between 25-56% are documented for both men and women engaging in agricultural activities. In men, the authors find increased kidney cancer in those “working with rapeseed and sunflowers, and tasks related to other crops such as corn, wheat/barley, beet, and tobacco.” In women, an increased risk is noted for winegrowers and corn growers. “Pesticide use (on fields and/or seeds) was associated, for both sexes, with these crops, showing exposure-response relationships with crop area and work duration,” the researchers state. This study, of a large cohort of agricultural workers, highlights the disproportionate risks of adverse kidney health to farmworkers directly handling pesticides or encountering pesticide residues on recently treated products. According to the World Cancer Research Fund, kidney cancer is the 14th most common cancer worldwide, affecting men more often than women. Kidney cancer incidence and mortality have increased globally, with various causes, such […]

(Beyond Pesticides, February 26, 2026) Published in PLOS ONE, research in Brazil “analyzed the impact of occupational/household chronic exposure to pesticides on the clinicopathological profile of breast cancer in rural women from Paraná southwest, a predominantly rural landscape with large pesticide uses,” finding that “pesticide exposure favors the occurrence of more aggressive breast cancer.” The study highlights the disproportionate risks of pesticides to farmworkers, focusing on women, as it compares exposed and unexposed populations and breast cancer tumor/disease characteristics. One of the study authors, Carolina Panis, PhD, discussed her earlier research at the Beyond Pesticides’ 42nd National Forum Series, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature. In her previous work, Pesticide exposure and increased breast cancer risk in women population studies, Dr. Panis documents a number of pesticides that “can increase the risk of BC [breast cancer] development through various mutagenic [genetic mutations] and nonmutagenic mechanisms and can act directly as carcinogens or indirectly as biochemical modifiers and hormonal deregulators. The underlying mechanisms include endocrine disruption; genotoxicity; epigenetic changes [changes to gene function without changing DNA]; enhanced cell migration, invasion, and…” more. Dr. Panis and other researchers at the Forum support community-level understanding of the […]

(Beyond Pesticides, February 19, 2026) A study published in Scientific Reports highlights the benefits of organic agriculture in comparison to different farming systems over five years on four crops (maize, tomato, faba bean, and potato). “Soil carbon sequestration is a long-time storage of carbon in soil which represents 70% of the carbon in land,” the authors note. “Therefore, the main aim of this study is to investigate the effect of the agricultural practice systems on the soil carbon sequestration and properties, productivity, water consumption, soil carbon sequestration, CO2 emission and cost of some agricultural crops.” As a result, the experiment reveals that, compared to chemical-intensive farming, organic methods enhance soil properties, reduce water consumption, provide higher yields and higher soil carbon sequestration, reduce CO2 emissions, and achieve the highest total net profit for all four crops after five years. Study Importance The topic of food security and sustainable agricultural systems is a crucial one, particularly as environmental degradation escalates. “Recently, organic agricultural systems have drawn much attention as alternative ways to produce food and ensure security in terms of environmental sustainability,” the researchers say, while Beyond Pesticides and organic advocates have been discussing the viability of organic agriculture for decades. […]

(Beyond Pesticides, February 18, 2026) Research finds that widespread agricultural pesticide use increases chronic dietary exposure in poultry and leads to adverse reproductive effects, despite meeting legal residue limits. As published in Poultry Science by researchers in Poland, the study analyzes low-dose exposure of roosters (Gallus gallus domesticus) to the fungicide tebuconazole (TEB), the insecticide imidacloprid (IMI), and the weed killer glyphosate (GLP) individually and in mixtures, with all concentrations at or below the maximum residue limits (MRLs) established by the European Union (EU). “Sub-MRL pesticide exposure impaired male reproductive function, with the most pronounced effects observed following combined treatments,” the authors report. They continue: “[E]xposure resulted in reduced semen quality, decreased fertility and hatchability, and increased embryo mortality, particularly in groups receiving IMI alone or in combination. These functional impairments were accompanied by detectable pesticide residues in reproductive tissues and body fluids, as well as modulation [modification/alteration] of local and systemic immune parameters.” The results of the experiment highlight how combined pesticide exposure, resulting from common use of multiple pesticide active ingredients concurrently, produces “stronger and more persistent reproductive effects than individual compounds, indicating mixture-specific toxicity.” This study is particularly important, as it represents the chronic exposure to MRL-compliant […]

(Beyond Pesticides, February 13, 2026) In a novel, continent-wide study of soil biodiversity throughout Europe published in Nature, researchers find 70% of the sampled sites contain pesticide residues, which “emerged as the second strongest driver of soil biodiversity patterns after soil properties,” particularly in croplands. As soil biodiversity is key for ecosystem functioning, agricultural and land management practices that safeguard biodiversity are imperative. This study, however, highlights how pesticides alter microbial functions, including phosphorus and nitrogen cycling, and suppress beneficial taxa, such as arbuscular mycorrhizal fungi and bacterivore nematodes, and adds to a wide body of science that links pesticide residues in soil to adverse effects on biodiversity. In analyzing 373 sites across woodlands, grasslands, and croplands in 26 European countries, and examining the effects of 63 pesticides on soil archaea, bacteria, fungi, protists, nematodes, arthropods, and key functional gene groups, the data reveals “organism- and function-specific patterns, emphasizing complex and widespread non-target effects on soil biodiversity.” As the authors state, “[T]o our knowledge, ours is the first study to demonstrate the relative importance of pesticides in comparison to soil properties, ecosystem type and climate at a continental scale.” Study Importance As Kristin Ohlson describes in her book The Soil […]

(Beyond Pesticides, February 10, 2026) Species that are integral to pest management allow for crucial ecosystem services that negate the need for pesticides in agricultural or land management practices. In a study published in Agriculture, Ecosystems & Environment, researchers from France find pesticide-free fields promote carabid beetles and spiders, generalist arthropod predators that consume slugs, aphids, and mites, that in turn support healthy, organic systems. The study findings highlight the importance of utilizing farming practices that promote biodiversity and foster natural enemy populations as a pest management strategy.   “In this study, we assessed the assemblages of emerging and circulating ground-dwelling carabids and spiders during four months in a continuous mosaic of pesticide-free winter-sown crops under contrasted tillage regimes (minimum vs. conventional tillage) and sown flower strips bordering fields,” the authors describe. They continue: “We detected clear patterns, with high in-field carabid and spider overwintering densities than in adjacent flower strips… Our results also demonstrate the key role of pesticide-free fields under minimum tillage, acting both as a high-quality overwintering site for some dominant carabid species and as a source habitat, as several predator species activity-density responded positively to the increased area of minimum tillage fields in the surroundings.” Background […]

(Beyond Pesticides, February 6, 2026) The United States, under Donald Trump’s direction, has withdrawn from 66 international organizations, the most important for health being the United Nations’ World Health Organization (WHO) and the Intergovernmental Panel on Climate Change. International organizations committed to the application of the best available science and policy development via consultation and consensus serve as a vital check against rampant personal and industry nest-feathering at the expense of global health. The Trump administration has removed this check while expanding his and his associates’ self-dealing and dismissing the critical interactions of crises such as climate change and synthetic chemicals. Although Trump announced this move on inauguration day last year, the completion of the process last week puts the stamp of finality on his total abandonment of public health. This in turn threatens the collapse of WHO—and even the U.N.—altogether, which has wide implications for agriculture, particularly pesticide policies, climate action (and inaction), and infectious disease monitoring, including vaccines and pandemic prevention. [See commentary: On Public and Environmental Health and Worldwide Collaboration.] Other U.N. environmental, health, and agricultural organizations on the list are groups focused on forest degradation, freshwater and oceans, mining, minerals, metals, and sustainable development, biodiversity, and ecosystem […]

(Beyond Pesticides, February 3, 2026) In analyzing the direct and indirect effects of pesticides that act simultaneously upon macrozoobenthos communities (invertebrates living in or on sediment) in standing small water bodies (SWBs) in Germany, researchers find high risks to biodiversity and ecosystem functioning. Published in Hydrobiologia, the experiment finds high risks to invertebrates and highlights how both direct and indirect effects are vital to comprehensive assessments of pesticides. While typically overlooked in regulatory reviews, SWBs are defined as shallow standing or running freshwaters “with a surface area of less than 50 hectares (ha),” such as lakes or ponds, including farm ponds, as well as headwater streams, springs and flushes, and ditches. SWBs are biodiversity hotspots that contribute to numerous ecosystem services and are adversely affected by agricultural land use effects such as pesticide contamination. “Holistic assessments of pesticide effects on invertebrate communities in standing small water bodies have, however, not yet been successful,” the authors note. To address this, the researchers developed an indicator for evaluating pesticide impacts on macrozoobenthos communities, populated with aquatic invertebrates, such as snails, worms, crayfish, and clams, through indirect toxic effects on aquatic plants called INPOND: INdirect Pesticide impacts ON Diversity in standing small water […]

(Beyond Pesticides, February 2 2025) With the Trump administration withdrawing from international organizations that historically advance a shared world view of global sustainability (from health and the environment, to peace and justice), people are calling on the U.S. Congress and state governors to support critical health and environmental programs that link humanity across the globe. Beyond Pesticides is collaborating on an action to: Tell Congress to support and fund international organizations critical to the global health of humans and the biosphere, AND Tell Governors/Lieutenant Governors to join (as well as thank them for joining) the Governors Public Health Alliance and to expand their support for international agencies that protect biodiversity and mitigate the climate crisis (IUCN, IPBES, and IPCC).  Will the U.S. Congress and state government step up to link across national borders when the Trump administration steps back from worldwide existential health and environmental crises? Among the 66 organizations affected by this action are the World Health Organization (WHO), the International Union for Conservation of Nature (IUCN), the Intergovernmental Science Policy Platform on Biodiversity and Ecosystem Services (IPBES), and the Intergovernmental Panel on Climate Change (IPCC). These organizations all support global health, and withdrawing from them is “contrary to the interests of the United […]

(Beyond Pesticides, January 28, 2026) A study published last year in Science of The Total Environment reports widespread pesticide contamination collected from beehive monitoring across the European Union (EU). “This study has produced the first EU-wide distribution map of terrestrial pesticide contamination and demonstrates widespread pesticide contamination of EU environments,” the authors write. The study, led by a cohort of citizen-scientists, documents pesticide drift across the European continent. The results found that 188 of the 429 targeted pesticide compounds were detected in noninvasive, in-hive passive samplers (APIStrips) across 27 EU countries between May and August of 2023. This finding emerges at a time when public health and environmental advocates raise concerns about the European Union’s backtracking on commitments to reduce pesticide use by 2030, although the European Commission announced in July 2025 that “the use and risk of chemical pesticides has decreased by 58% by 2023 [from the 2015-2017 reference period], while the use of more hazardous pesticides fell by 27% over the same period.” Results The study results reveal that no landscape is safe from pesticide exposure, despite the European Union having better regulations in place than most other countries/regions. The researchers found: “There was no sample site where […]

(Beyond Pesticides, January 15, 2026)  “Birds and bats consumed over 87 rice pest species in West African lowland rice fields,” according to a recent study published in Agriculture, Ecosystems & Environment. The authors continue, “Our findings highlight the importance of maintaining and managing a diverse community of bats and birds for network resilience.” In this context, the research distinguishes the “predator-prey” as established through the ecological balance of diverse organisms in nature from a “predator-pest” orientation that views some organisms as unwanted and targets for control and more subject to human manipulation.  The authors describe the predator-pest network as a means to quantify the “ecosystem services” impact, with the researchers noting that they “investigated the role of predator and prey species in the predator–prey network and compared those roles with that of the predator–pest network, to further explore their potential as pest suppressors.” Communities across the United States and globally are looking for opportunities to transition to alternative pest management strategies given decades-long increasing reliance on synthetic pesticides and fertilizers, which contribute significantly to looming existential crises of biodiversity collapse, public health decline, and planetary instability of ecosystems, climate, and geopolitics. As evidenced in a recent report by Farm Action […]

(Beyond Pesticides, January 14, 2026) Adverse neurodevelopmental outcomes in children 4–6 years old occur with reported maternal occupational exposure during pregnancy, as published in a study in PLOS One, according to research from Muhimbili University of Health and Allied Sciences in Tanzania and the Centre for International Health at the University of Bergen in Norway. “Our results show that self-reported maternal exposure to pesticides through direct spraying during pregnancy was associated with lower scores in social-emotional and executive function domains among children,” the authors state. Additionally, the authors note that they found an association between social-emotion scores in children and weeding practices of their mothers during pregnancy, as well as reduced overall neurodevelopmental scores following direct maternal pesticide exposure. The study, conducted through self-reported pesticide exposure from the mothers of 432 mother–child pairs in three horticulture-intensive regions in Tanzania and development and learning assessments of their children, reflects the “concerns about maternal occupational exposure during pregnancy and its potential impact on child neurodevelopment,” the researchers describe. Current risk assessments fail to properly capture the disproportionate risks to farmers and farmworkers with various routes of exposure, “particularly in horticultural settings where women of reproductive age represent a substantial proportion of the […]

(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, December 4, 2025) In a news release last week on November 26, 2025, the U.S. Environmental Protection Agency (EPA) “issued a comprehensive fact-check addressing dangerous misinformation circulating about EPA’s recent pesticide approvals” that, according to health and environmental advocates, continues to deceive the public about the true risks for health and the environment from petrochemical pesticides including, but not limited to, per- and polyfluoroalkyl substances (PFAS). Also published on November 26, coverage titled The EPA Is Embracing PFAS Pesticides. These Are The Health Risks in Time further highlights EPA’s deficiencies and the threats of PFAS, which Beyond Pesticides has extensively covered. (See here and here.)  The controversy erupted as a result of EPA’s latest proposal to allow a new fluorinated pesticide to the list of four other similar compounds now widely available for use in homes and gardens, buildings, and agriculture. The newest pesticide proposed for EPA registration, epyrifenacil (agricultural weed killer), joins cyclobutrifluram (soil fungicide/nematicide), isocycloseram (household and agricultural insecticide), diflufenican (lawn and agricultural weed killer), and trifludimoxazin (agricultural weed killer), making a total of five PFAS pesticide proposals this year that have been associated with national and worldwide contamination of food, land, and water. Two of these, cyclobutrifluram and isocycloseram, have been approved. “Instead of constraining the use of fluorinated pesticides—persistent and highly toxic […]
