(Beyond Pesticides, December 16, 2025) Through a literature review and data analysis of almost 2,000 soil samples, the authors of a recent study find negative effects on the presence of plant-beneficial bacteria (PBB) in soil with pesticide exposure, particularly bacteria with plant growth-promoting traits that are essential for crop productivity. The study, published in Nature Communications, by researchers at Chinaâs Shaoxing University and Zhejiang University of Technology, adds to scientific literature documenting the effects of pesticides on soil health. âPesticides not only reduce PBB diversity as individual factors, but they also exert synergistic negative effects with other anthropogenic factors… further accelerating the decline in PBB diversity,â the researchers state. They continue, âIncreased pesticide risk also leads to a loss of functional gene diversity in PBB about carbon and nitrogen cycling within essential nutrient cycles, and a reduction in specific amino acid and vitamin synthesis.â In elucidating these impacts, this study reinforces previous research that connects pesticide use with deteriorating soil health, further stressing the urgent need for adopting a systems-wide transition to organic agricultural and land management practices. Soil Microbiome Health As the authors discuss, plantâsoilâmicrobe interactions play a critical role in the growth, development, and overall health of plants, […]

(Beyond Pesticides, November 24, 2025) In his article on ecological traps, Professor Danilo Russo, PhD, explains the harm caused to wildlife from well-intentioned efforts to establish habitat on chemical-intensive farms or areas otherwise subject to chemical exposure. Dr. Russo et al., in âTo improve or not to improve? The dilemma of âbat-friendlyâ farmland potentially becoming an ecological trapâ (2024), write, â[W]hen restoring habitats for bats in conventional farmland, potential unintended outcomes must be considered, particularly if restoration actions are not accompanied by mitigation of key threats. These threats include the persistent and widespread use of pesticides. . .â (See also a study in Environmental Entomology, which shows that habitat and open space near agricultural fields become a killing field of pesticides, threatening biodiversity due to contamination from toxic drift.) As this false sense of protection persists, Beyond Pesticides is calling on governors to adopt policies that support organic land management and ecological balance. Organic practices are, by definition, a systems change that is aligned with nature and the biodiversity protection that is needed. Ecological traps are incremental steps that fail to address underlying systemic problems that allow hazards to persist. While they represent an affirmative action in an attempt to adopt restorative measures, the […]

(Beyond Pesticides, November 19, 2025) In the book, Biological Control Systems and Climate Change, published this month, Danilo Russo, PhDâa speaker during the first session of our 42nd National Forum, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Natureâand other researchers add to the existing literature on the climate change threat to ecosystem services. Dr. Russoâs chapter, entitled âImpact of Climate Change on Bats Involved in Biological Control,â explains one of the lost benefits of ecological balance attributable to the climate crisis. As explained in the book: âIn 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.â The ability of climate change to influence the effectiveness of biological control systems is explored, showing the âeffects 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.â 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 4, 2025) A study of earthworms published in Environmental Science & Technology highlights how chemical mixtures can have both synergistic and species-specific effects, threatening the soil microbiome and overall soil health. In exposing two species, Eisenia fetida and Metaphire guillelmi, to the weed killer glyphosate alone and in combination with urea, a form of synthetic nitrogen fertilizer, the researchers find enhanced toxicity with co-exposure as well as varying health effects between the two species. These results emphasize the need to test a wide variety of nontarget organisms for impacts from environmental contaminants, since species, even within the same genus or family, can exhibit vastly different effects. Glyphosate, as one of the most widely used herbicides worldwide, is highly researched, with a multitude of studies linking the weed killer to effects on humans, wildlife, and soil ecosystems. Since simultaneous application of glyphosate and urea frequently occurs in agriculture, the effects of this mixture on earthworms are crucial for understanding the overall impacts on soil health. In exposing the two species to the individual compounds and as a mixture, the authors report increased glyphosate residues in earthworm gut contents, reduced body weight, aggravated intestinal tissue damage, sharply decreased digestive […]

(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 Pesticidesâ 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 âThe complex web between environmental disruption, pesticide use, and human health: lessons from the bat crisis,â states: âThe 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.â 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. âThis systematic review identifies, critically evaluates, and synthesizes recent global literature (2015â2024) on pesticide residues detected in seaweeds to delineate contamination patterns,â 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 26, 2025) National Public Lands Day on Saturday, September 27âfirst established in 1994 and held on the fourth Saturday of Septemberâis 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 yearâs theme, âOur Home Outdoors,â is explained by NEEF as: âOur public lands are more than just places to visitâthey 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.â 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. âWe 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,â 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 Pesticidesâ 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 18, 2025) Published in Environmental Toxicology and Pharmacology, a study of earthworms (Eisenia fetida) evaluates the toxicity of environmentally relevant levels of three fluorinated pesticides (fluxapyroxad, fluopyram, and bixafen) through a 56-day soil exposure experiment. The dose- and time-dependent results reveal that effects on growth and reproduction occur at elevated concentrations, with weight loss and reduced offspring occurring from energy depletion and reproductive organ damage. Other implications escalate with concentration as well, including antioxidant system failure and DNA damage. As the authors summarize, âThese findings highlight the mechanisms of fluorine-containing pesticide toxicity in earthworms, emphasizing their potential to disrupt soil ecosystems.â Fluorine-containing pesticides are widely used in agriculture, yet the chronic effects on soil and soil organisms are not fully considered in regulatory review. Research comparing the similarities and differences in the impacts on nontarget organisms from fluorinated pesticides is lacking, with the current study beginning to address the urgent need to close this gap. âData indicate that among more than 100 newly developed pesticides, fluorine-containing pesticides constitute nearly half, making them a focal point in the development of the global pesticide industry,â the researchers state. As representatives of the fluorinated pesticides class, particularly succinate dehydrogenase inhibitors […]

(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. âArable systems have a high dependence on diverse natural biota to support pest control, soil bioturbation, and nutrient recycling,â 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, July 18, 2025) A study in Royal Society Open Science shows intraspecific differences (between individuals of a species) in wild bumblebees (Bombus vosnesenskii) exposed to an herbicide (glyphosate), a fungicide (tebuconazole), and an insecticide (imidacloprid), with gut microbiome health as a factor. âWild pollinator declines are increasingly linked to pesticide exposure, yet it is unclear how intraspecific differences contribute to observed variation in sensitivity, and the role gut microbes play in the sensitivity of wild bees is largely unexplored,â the authors explain. âHere, we investigate site-level differences in survival and microbiome structure of a wild bumble bee exposed to multiple pesticides, both individually and in combination.â In collecting 175 individuals of this wild, foraging species from an alpine meadow, a valley lake shoreline, and a suburban park and exposing them to a diet with individual pesticides and mixtures, the researchers assess the varying lethal and sublethal effects that can occur with pesticide exposure. Between the three sites, the survival differences âemphasize the importance of considering population of origin when studying pesticide toxicity of wild beesâ and highlight how pesticide sensitivity not only varies between species but within individuals of the same species with site-specific impacts. (See previous Daily […]

(Beyond Pesticides, July 16, 2025) A study following a mass mortality event of approximately 200 monarch butterflies (Danaus plexippus plexippus) in Pacific Grove, California, highlights the role of pesticides, synthetic pyrethroids in particular, in causing lethal and sublethal effects to nontarget organisms. The research, published in Environmental Toxicology and Chemistry, detects residues of 15 pesticides and associated metabolites in the bodies of 10 deceased butterflies collected from the January 2024 event that occurred near an overwintering site frequented by monarchs. âOn average, each monarch butterfly contained 7 pesticides,â the authors report. They continue, âNotably, three pyrethroid insecticidesâbifenthrin, cypermethrin, and permethrinâwere consistently detected at or near each chemicalâs lethal dose (LD50).â LC50, or Lethal Concentration 50, values represent the concentrations of chemicals lethal to 50% of a test population. To assess pesticide residues within ten of the deceased butterflies, the researchers use liquid and gas chromatography with tandem mass spectrometry (LC-MS/MS and GC-MS/MS) and find âa total of 15 pesticides and associated metabolites in the butterflies, including 8 insecticides (plus 1 associated metabolite), 2 herbicides (plus 2 associated metabolites), and 2 fungicides.â The study âpresent[s] evidence that the mortality incident at the Pacific Grove Monarch overwintering site was likely caused by […]

Image: Art Page submission from Sara Grantham, âPollen Song.â (Beyond Pesticides, June 20, 2025) A study in Conservation Genetics, entitled âOrganic farming fosters arthropod diversity of specific insect guilds â evidence from metabarcoding,â showcases the negative effect of chemical-intensive, conventional farm management on insect populations when compared to organically managed meadows. The researchers find that the diversity and biomass of flying insects are higher with organic land management by 11% and 75%, respectively. âWe report a higher diversity on organic meadows in comparison with conventional ones, all over the diversity of flying insects and not only based solely on a few species-poor groups as in previous studies,â the authors state. They continue: âWe found significant richness differences between management types and increased functionality on organic meadows. Our results imply the superiority of organic farming in comparison to conventional farming in the conservation of insect diversity.â The topic of insect biodiversity and the decline of insect populations over the last few decades, also referred to as the insect apocalypse, has been extensively covered by Beyond Pesticides. As previously reported in the Daily News, âContinued Decline in Insect Species Biodiversity with Agricultural Pesticide Use Documented,â insects provide many important services, such as […]

***Featured Art Page submissions for National Pollinator Week, highlighted with the gratitude of Beyond Pesticides: Jesse from Livermore, CA: “Honeybee Pollinating Citrus Blossom”; Yumi from New York, NY: “Birds and the Bees”; Gretchen from Helena, MT: “Butterflies”; Janet from Concord, MA: “Beneath the Big Dipper”; and Trix from Petersburg, NY: “Downy Woodpecker.” (Beyond Pesticides, June 16, 2025) Every year, Beyond Pesticides announces National Pollinator Week to remind eaters of food, gardeners, farmers, communities (including park districts to school districts), civic organizations, responsible corporations, policy makers, and legislators that there are actions that can be taken that are transformative. All the opportunities for action to protect pollinators, and the ecosystems that are critical to their survival, can collectively be transformational in eliminating toxic pesticides that are major contributors to the collapse of biodiversity. This is why Beyond Pesticides starts most discussions and strategic actions for meaningful pollinator and biodiversity protection with the transition to practicing and supporting organic. In launching National Pollinator Week, Beyond Pesticides makes suggestions for individual actions to increase efforts to think and act holistically to protect the environment that supports pollinators. The impact that people have starts with grocery store purchases and the management of gardens, parks, […]

(Beyond Pesticides, June 5, 2025) A study conducted in Pennsylvania and published in Environmental Entomology highlights threats to nontarget organisms from neonicotinoid insecticide exposure. Using species of ground beetles as an example, the study documents sublethal behavioral effects as well as decreased week-long survival. This research fills a notable gap in current research, with the authors explaining, âPredatory soil arthropods are under-represented in insecticide toxicity studies, severely limiting our understanding of how insecticides affect soil-invertebrate communities in agroecosystems.â Â The researchers continue, âAs a step toward addressing this issue, we conducted novel acute oral, topical, and soil-based toxicity assays on 9 ground beetle species (Coleoptera: Carabidae) in response to the neonicotinoid insecticides clothianidin, thiamethoxam, and imidacloprid.â The nine carabid beetle species, all common to agroecosystems in central Pennsylvania, were exposed to clothianidin, while additional assays with thiamethoxam and imidacloprid were conducted on the two most abundant species. A wide body of science exists that connects neonicotinoid exposure to health effects in a variety of nontarget organisms. Neonicotinoids, a class of neurotoxic insecticides, act as agonists of nicotinic acetylcholine receptors, âpersist under field conditions, and are water soluble, enabling them to translocate into plants and provide systemic protection of seedlings,â the […]

(Beyond Pesticides, May 13, 2025) A study in Environmental Pollution examines ecological and health risks in farmland soil with pesticide contamination. âAlthough agricultural soil pesticide residues have long threatened the environment, a relatively complete system for evaluating their health and ecological risks has not yet been developed,â the authors state. In addressing this research gap, the study finds that âmore than ten pesticides were detected in 98.62% of the soil samples, which changed the soil environmentâ and threatens the health of the soil microbiome. The authors continue, âThis study investigated the correlation between pesticide residue risks and soil ecological security and human health, revealed the response characteristics of soil microbial communities under pesticide stress, and identified microbes strongly related to pesticide ecological risks.â Pesticides, as the authors emphasize, âinevitably pollute agricultural soil, affect the ecological environment, and pose a threat to human health.â (See studies here, here, and here.) With this in mind, they assess 50 selected pesticides in 145 soil samples from agricultural land in Zhejiang Province, China and calculate the associated risks to ecosystems and public health. In describing the importance of this research, the authors explain: âPesticides are prone to leakage and drift in environmental media, turning […]

(Beyond Pesticides, May 9, 2025) Research in Advances in Modern Agriculture showcases how pesticide residues can threaten the health of soil nematodes and cause phytotoxic effects in cucumber plants. In assessing both the sprayed vegetables and the organisms within the soil, the authors find a negative correlation between pesticide exposure and soil nematode populations that is proportional to the application rates of the chemicals, as well as alterations in plant development. These impacts highlight potential wider effects on crop productivity, biodiversity, and human health. âNematodes, which are microscopic worms inhabiting the soil, are vital contributors to soil vitality and the cycling of nutrients,â the authors share. âNonetheless, the non-selective and widespread application of pesticides can negatively impact these organisms, leading to potential detriments in soil quality and plant vitality.â âPesticide residues have the propensity to be absorbed and progressively accumulate as they traverse from soil to plants and subsequently to humans,â the researchers state. They continue, âThe specific characteristics of the pesticide and its interactions with the body across different levels dictate whether it will be excreted without causing significant harm or if it will accumulate, potentially leading to enduring subclinical and clinical ramifications.â The impacts vary widely between organisms […]

(Beyond Pesticides, May 6, 2025) A study in Ecology Letters finds âsevere degradation of ecosystem functioning in the form of loss of organic matter consumption and dramatic shifts in primary productivity,â the researchers state, after performing an experiment with â36 naturally established freshwater ecosystems exposed to increasing field-realistic concentrations of the neonicotinoid thiacloprid.â Aquatic communities contribute to overall biodiversity and are crucial in maintaining healthy ecosystems; without them, the entire food web and vital ecosystem services, such as nutrient cycling, water filtration, and climate regulation, are threatened. As the authors reference, there is a current unprecedented decline in biodiversity that can be attributed to anthropogenic impacts. A multitude of studies connect pesticides, and more specifically neonicotinoid insecticides, to impacts on aquatic ecosystems. (See studies here and here.) âSince the community of organisms locally present is responsible for the functioning of the local ecosystems,â the researchers begin, âthis begs the question: do neonicotinoid-induced shifts in community composition result in a degradation of ecosystem functioning?â Previous research finds that neonicotinoids can âimpede several freshwater ecosystem processes such as organic matter (âOMâ) decomposition, primary production or biomass transfer to neighbouring ecosystems,â the authors say. (See studies here, here, and here.) They continue: âHowever, […]

(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 exposureâhighlighting the threats to grassland insect communities that are disregarded in risk assessments. By assessing the effects of MospilanÂŽSG, 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. âAlthough 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,â the authors state. They continue: âIn 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, March 20, 2025) An article, published by the National Audubon Society, titled âA Sweeping New Report Shows U.S. Birds Declining Sharply Across a Range of Habitatsâ reviews the latest State of the Birds 2025 report and finds concerning news for bird species across the country. As the article says: âWhether they hop around the prairie, dabble in wetlands, flit through forests, or forage along the shore, birds are suffering rapid population declines across the United States… If these habitats are struggling to support bird species, itâs a sign that theyâre not healthy for other wildlife, or even humansâbut working to restore them will have benefits across ecosystems.” The 2025 edition of the State of the Birds report, showcasing a status assessment of the health of the nationâs bird populations, was cultivated by scientists from bird conservation groups through the U.S. Committee of the North American Bird Conservation Initiative (NABCI). The report notes, âDespite ample evidence that conservation can work, the status quo approach to conservation is not turning bird populations around.â As NABCI shares, the report contains â[s]obering evidence that Americaâs birds continue to decline across the board.â They continue, saying: âBirds are telling us that the habitats […]

*** Beyond Pesticides has recently received an insulting broadside from an environmental group; click here to read the original email and a response from the organization that includes a deep history of Beyond Pesticidesâ commitment to ecological and organic farming practices in local food systems that are just. (Beyond Pesticides, February 26, 2025) The National Park Service (NPS) recently announced a settlement agreement regarding the management of northern Californiaâs Point Reyes National Seashore (PRNS) that will result in the closure of 12 out of 14 historic dairy and cattle ranches, including those organically managed, within the park. This decision comes after nearly a decade of legal disputes and negotiations between environmental groups, ranchers, and the NPS, ending 170 years of family ranching, displacing multi-generational farmersâat least 90 farmworker familiesâand abandoning 77 historic ranch buildings. Critics lambast the agreement as devastating local organic agriculture and food production in West Marin County, which is essential for creating long-term climate solutions. Over the decades since PRNSâ inception, local and national environmental groups have litigated against ranchers and the National Park Service, including demanding range expansion for the native tule elk, which were reintroduced to the park by NPS in the 1970s. However, the […]

(Beyond Pesticides, February 19, 2025) In Global Ecology and Conservation, a study of bat species in organic desert date palm plantations highlights the invaluable ecosystem services these beneficial organisms provide. âBats are crucial in suppressing pest arthropods in agroecosystems, contributing vitally to sustainable agriculture,â the study authors share, which makes supporting bat populations important not just for biodiversity but to help enhance their roles in pest management. Â Â There are various studies connecting organic agriculture and the value it provides for bats and their ecosystem services. (See studies here, here, and here.) While many studies also recognize bat species threatened by pesticides, habitat loss, and climate change, “the importance of bats in agriculture in extreme environments, such as deserts, has received far less attention,â the researchers state. (See previous coverage on pesticide exposure and bats here and here.) They continue, âDate palm plantations represent one of the few productive systems in hyper-arid regions,â noting the studyâs novel design. The date palm, primarily grown throughout the Middle East and North Africa, is one of the earliest domesticated fruit trees. âThe date palm cultivationâs monocultural nature increases susceptibility to pest infestations due to limited plant diversity, involving 112 mite and insect species.â […]
