(Beyond Pesticides, January 2, 2026) Texas-based pecan orchard Swift River Pecans is collaborating with local conservation nonprofit Merlin Tuttle’s Bat Conservation “so they could collect more information on the species that visit his 266-acre property, and to show off the bats’ value to his operation,” according to recent coverage by NPR affiliate KCUR. “Bats love to munch on insects like stink bugs and moths. Some farmers are now relying on the mammals for pest control – and ditching chemicals,” says Michael Marks, reporter for NPR (Harvest Public Media) and Texas Standard. The orchard operator and nonprofit have been collaborating since 2004, after Troy Swift (orchard owner) employed a chemical-intensive approach since purchasing the land in 1988. Merlin Tuttle, “an ecologist and conservationist who has spent 65 years studying bats around the globe,” has been setting up bat boxes using cypress trees from a lumber mill on-site—the researcher has opted for this wood type because it is porous and regulates temperature appropriately. “Our job is to work with Mother Nature instead of against her to make the best pecans money can buy. That’s the way we see it,” says Mr. Swift, who also serves as the president of the Texas Pecan […]

(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 23, 2025) A global literature review of pesticide residues in marine seaweed, published in Marine Pollution Bulletin, highlights the widespread presence of pesticides in bioindicator species. As vital coastal primary producers, seaweed acts as a key indicator for regional pesticide contamination patterns. The bioaccumulation within seaweed species also threatens consumers, including humans, as the chemicals can biomagnify as they move through the food web. Pesticide contamination in waterways allows residues to bioaccumulate in seaweed species, presenting risks to public health, biodiversity, and ecosystem functioning. In addition to the support seaweeds provide for ecosystems, they provide food sources for a multitude of organisms and are of growing socioeconomic importance. “This systematic review identifies, critically evaluates, and synthesizes recent global literature (2015–2024) on pesticide residues detected in seaweeds to delineate contamination patterns,” the authors share. The findings highlight the harmful impacts of petrochemical pesticides on multiple species. Many aquatic species rely on seaweed as a food source, including fish, sea urchins, crabs, snails, brittle stars, and marine mammals such as manatees and sea turtles. Even bacteria and filter feeders consume seaweed when it is decomposed. Birds and land mammals also consume seaweed, including humans who utilize seaweed in various […]

(Beyond Pesticides, September 19, 2025) In Water Science and Engineering, a study investigating the occurrence and distribution of agricultural pesticides in a river–lake system of the Taihu Lake Basin in China through surface runoff finds adverse effects on nontarget organisms that threaten ecological security. In evaluating the risks to aquatic organisms, the researchers highlight how pesticide residues in surface water and sediments jeopardize the entire food web, as risks are present throughout multiple trophic levels (positions in the food chain). The results show that in surface waters, the fungicide carbendazim is the dominant pollutant with 23.66% of the contamination. Within the sediment samples, the fungicide tebuconazole is the primary contributor at 28.57%. Overall, fungicides are the main type of pesticide present in the tested river water and sediments. These compounds account for 76.86% and 85.10% of contamination, respectively. The authors also note that pesticide concentrations in both water and sediments in the rivers increase while moving downstream. “Ecological risk assessment revealed high mixed risks to algae, daphnia [water fleas], and fish, with risk levels rising along with trophic levels of aquatic organisms,” the researchers state. They continue, “[C]ertain pesticides posed high risks to algae even at low concentrations, indicating more […]

(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 11, 2025) A study published in Agriculture, Ecosystems & Environment finds organic rice paddies in the Mediterranean region have greater ecosystem biodiversity, including increased presence of aquatic microorganisms and insects, than their chemical-intensive counterparts. While not a “cradle-to-grave” or holistic analysis of organic vs. chemical-intensive agriculture (see a similar example in previous Daily News here), the authors note that there is an increase in greenhouse gas emissions (GHGe) associated with compost use, which replaces synthetic fertilizers. Typically, compost builds biological life in the soil and contributes to a drawing down (or sequestering) of atmospheric carbon. As EPA notes, “[C]omposting lowers greenhouse gases by improving carbon sequestration in the soil and by preventing methane emissions through aerobic decomposition, as methane-producing microbes are not active in the presence of oxygen.” The transition to organically produced rice in the U.S. has come with challenges. One includes thorny debates over the inclusion of copper sulfate on the National List of Allowed and Prohibited Substances, which establishes materials permitted for use in certified organic production under the Organic Foods Production Act (OFPA). Under the law, USDA restricts copper sulfate in organic farming as follows: “For use as tadpole shrimp control in aquatic […]

(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.

(Beyond Pesticides, April 15, 2025) A study in Communications Earth & Environment, through field, greenhouse, and laboratory experiments involving three plant bug species, finds both species-specific and sex-specific sensitivity responses to neonicotinoid insecticide exposure—highlighting the threats to grassland insect communities that are disregarded in risk assessments. By assessing the effects of Mospilan®SG, with the active ingredient acetamiprid, the researchers determine that nontarget plant bug species are highly sensitive to neonicotinoids and face community-level harm with exposure. As systemic insecticides, neonicotinoids move through the vascular system of plants, expressing the poison through pollen, nectar, and guttation droplets. As persistent pesticides, these chemicals indiscriminately poison insects and organisms in the soil. “Although pesticides have been proposed as one of the main causes of insect decline, there are still few studies assessing their effects on non-target species under field conditions,” the authors state. They continue: “In this study, we address the existing research gap on insecticide exposure of non-target herbivorous insects, focusing on two main aspects: (1) realistic exposure scenarios, (2) community-level effects, i.e., differential sensitivity between closely related species and between sexes of the same species. We chose plant bugs (Heteroptera: Miridae) as a model group because they are one of the […]

(Beyond Pesticides, April 11, 2025) In a new report by Save our Seeds Foundation on Future Farming, a consortium of EU-based scientists and bioethicists raise concerns about the implications and threats of generative artificial intelligence (GAI) for genetic engineering. Artificial intelligence will impact all aspects of society, including the acceleration of genetic editing tools that may lead to increased risks of harmful traits/genetic data being incorporated into products on the global marketplace. Organic farmers, conservationists, and public health professionals who collaborate with Beyond Pesticides grow increasingly concerned about the long-term impacts of deregulation and ongoing federal funding freezes and firings on needed regulatory oversight of the tech sector, including AI. Review of Save our Seeds Report So, what is artificial intelligence (AI)? AI is a broad field that focuses on building machines and systems that can think, learn, and solve problems—incorporating elements of human behavior. It powers things like voice assistants, self-driving cars, and recommendation systems on apps like Netflix or Spotify. In short, AI is designed to understand information, make decisions, and complete tasks intelligently. Generative AI, however, is an extension of AI focused on creativity. The main goal is to generate new content—whether in writing, photography, video, music, […]

(Beyond Pesticides, January 3, 2025) Pesticides that are sprayed and become airborne significantly disrupt ecological balances and affect nontarget species that are crucial for maintaining biodiversity, according to an article in Environmental Pollution. In this review of studies throughout countries in North and South America, Europe, and Asia, among others, researchers from Germany, Norway, the United Kingdom, and Poland reinforce the science about pesticides’ direct effect on species and the cascading effects of pesticide drift through various trophic levels within food webs that lead to overall devasting population effects. This study “addresses the interconnectedness of these impacts and illustrates the complex threats that pesticide drift poses to biodiversity across multiple ecosystems,” the researchers state. They continue: “Impacts include reduced reproductive rates, changes in growth, development, and/or behavior, modification of diversity or community organization, disruption of food webs, and declines of important species. Pesticides disrupt the delicate balance between species that define a functioning ecosystem. Impacts can be local, transnational, or even continental.” Pesticide drift threatens beneficial species and subsequently the entire agricultural system. The process of pesticide drift, “in which up to 25% of applied pesticides are carried by air currents, can transport chemicals over hundreds or even thousands of […]

(Beyond Pesticides, January 2, 2025) Adding to the body of scientific literature on the fast escalating antibiotic resistance crisis is a study published by Chinese scientists in Environmental Science & Technology, which shows that antibiotic resistance genes (ARGs) in soils move up through trophic levels via predation. Gut microbiomes of soil fauna have been found to be reservoirs of ARGs. How this process operates in soils is vital, because what happens in soil microbes does not stay there. If bacteria altered in soils move up trophic levels, ARGs may strengthen the multicellular agricultural pests the industry is trying to kill—insects, fungi, plants—not to mention bringing their libraries of resistant genes into the microbiomes of vertebrates, including humans. Antibiotic resistance is a natural phenomenon, but human activity has greatly increased its presence in ecosystems the world over, including in one of the ecological niches of greatest concern to the future of food and human health: soils. Soils are complexes of mineral and organic substrates populated by billions of microorganisms and tiny animals. They are rapidly being degraded by conventional agriculture, forestry, and land management practices generally—more than a third of the world’s agricultural land has already been severely damaged by pesticides, […]

(Beyond Pesticides, October 22, 2024) A recent study, published through the American Chemical Society, analyzes pesticide contamination in riparian soil and plants as a result of flooding from streams in Germany. The authors hypothesize, and then prove, that frequently flooded sites have higher levels of pesticides present due to the pesticides in surface waters contaminating the soil. Results show that the plant vegetation in the contaminated soil then takes up the pesticides, which bioaccumulate and lead to higher contamination that can further cascade throughout the ecosystem and affect terrestrial food webs. “[O]ur study provides evidence from the field that nontarget plant species typical for riparian stream sites receive considerable pesticide exposure via flooding events,” the authors share. This exposure, and subsequent bioaccumulation in plants, threatens the food web, as many riparian plants are a vital food source for insects. According to the authors, flooding events, and their impact on pesticide contamination within soil and plants, are rarely investigated. This study, “measur[ing] 98 pesticides and metabolites in plants and root-zone soils sampled at five streams situated in an area in Southwest Germany characterized by intensive agricultural land use,” highlights the differences in contamination between frequently flooded and rarely flooded areas and […]

(Beyond Pesticides, September 9, 2024)  Comments are due by 11:59 PM EDT on September 30, 2024. With the opening of the public comment period on organic standards that determine the integrity, strength, and growth of the organic agricultural sector, a study was released last week that shows degradation of the ecosystem linked to increased infant mortality associated with higher pesticide use by chemical-intensive farmers compensating for losses in bat populations. It is well known that bats, among other wildlife including birds and bees, provide important ecosystem services to farmers by helping to manage pest populations and increase plant resilience and productivity. While degradation of ecosystems is attributable to many factors, pesticide use accounts for an important element in harm to bats and biodiversity. The study, “The economic impacts of ecosystem disruptions: Costs from substituting biological pest control,” published in Science, concludes with a finding  that “insect-eating bat population levels induce farmers to substitute with insecticides, consequently resulting in a negative health shock to infant mortality.” Daily News will cover this study in depth in an upcoming edition. According to research published in the Journal of the Association of Environmental and Resource Economists (2022), bat population declines cost American farmers as much as […]

(Beyond Pesticides, July 26, 2024) Beyond Pesticides released the latest issue of Pesticides and You this week, a compendium of scientific research on pesticide threats to human and environmental health. The issue is a breathtaking warning from the science community that environmental, health, and labor laws are not protecting the public. Beyond Pesticides says in its introduction that a shift away from toxic pesticide use is urgently needed. Included in this issue are scientific reviews of research reported by Beyond Pesticides in 2023, providing a critique of the independent peer-reviewed literature with a shocking range of adverse effects, including cancer, neurotoxicity, brain effects, reproductive impacts, diabetes and obesity, chronic kidney and liver disease, Parkinson’s, respiratory illness and asthma, learning and behavioral abnormalities, and more, as well as disproportionate harm to people of color. In addition, the science documents pesticides’ catastrophic harm to the ecosystems that sustain life. In total, these dramatic findings call for an end to the use of toxic pesticides, incompatible with respect for living organisms and, to environmental, health, and labor advocates, unconscionable given the availability of viable, cost-effective organic practices. This issue adds to the body of knowledge from two previous issues of Pesticides and You (Transformative Change: […]

(Beyond Pesticides, July 8, 2024) Please submit comments by Wednesday, July 31, 2024. Acephate, an insecticide and member of the highly toxic organophosphate (OP) family, is so toxic that EPA is proposing to ban all uses except the systemic injection into trees. A comment period is open, and EPA is accepting comments through Wednesday, July 31, after extending the earlier July deadline. With this remaining use, EPA is still not recognizing that systemic neonicotinoid pesticides can cause serious environmental harm to the ecosystem through indiscriminate poisoning of organisms. >> Submit a comment on acephate and tell EPA that no pesticide should be allowed to be used if the crop can be produced organically.  EPA proposes to cancel all uses of acephate other than tree injection to eliminate all risks of concern it has identified that exceed its level of concern for dietary/drinking water risk, residential and occupational risks, and risks to non-target organisms. As Beyond Pesticides points out, although the tree injection method does not pose excessive dietary or aggregate health risk and does not pose any untoward occupational or post-application human health risks of concern, there are significant ecological risks posed that the agency has neglected. Rather than assessing the ecological risks of tree […]

(Beyond Pesticides, June 6, 2024) Researchers link pesticide exposure to behavioral effects on zebrafish (Danio rerio) larvae, signaling a larger issue for overall population and ecosystem effects. In a study published in Biomedicines, the authors conduct a multi-behavioral evaluation of the effects of three pesticides, both individually and as mixtures, on larvae. As the authors state, “Even at low concentrations, pesticides can negatively affect organisms, altering important behaviors that can have repercussions at the population level.” By analyzing effects on individual zebrafish with single compounds and mixtures, this study shows the dangers of pesticides in aquatic systems regarding synergy (a greater combined effect when substances mix) and the ripples created throughout entire ecosystems. Researchers from the Department of Morphology and Animal Physiology, as well as the Department of Physics, from the Rural Federal University of Pernambuco in Brazil collaborated with the Department of Biology at Indiana University in Indianapolis to perform the study. The researchers exposed zebrafish larvae to carbendazim, fipronil, and sulfentrazone to determine any behavioral effects on anxiety, fear, and spatial/social interaction for each compound separately and in combination. Each compound and mixture were applied to embryo medium, exposing fertilized zebrafish eggs. The embryos of zebrafish hatch, or […]
