(Beyond Pesticides, March 26, 2026) A review of pesticide exposure from a family member working in agriculture (“take-home” residues) finds that pesticide levels in the home are elevated between 2.6- and 3.7-times. This and other nonoccupational exposure data from homes are drawn from the Agricultural Health Study (AHS), a National Cancer Institute (NCI) and National Institute of Environmental Health Sciences (NIEHS) prospective study of cancer and other health outcomes in a cohort of licensed pesticide applicators and their spouses from Iowa and North Carolina. Between 1993 and 1997, with follow-up between 1999 and 2021, AHS tracks occupational and nonoccupational exposure and subsequent health effects from pesticide exposure. The current study, published in Environmental Advances, reexamines a quantitative analysis on nontarget, “active-ingredient-specific” exposure to pesticides from multiple pathways—applying new criteria to AHS spousal exposure to the insecticide chlorpyrifos and the herbicide atrazine. The three pesticide exposure pathways include take-home, agricultural drift, and residential use. Building on a 2019 study, researchers consider data from additional studies published between 2019 and 2024, “providing support that all three pathways contribute to pesticide exposure.” More importantly, the updated estimates of nontarget exposure to chlorpyrifos and atrazine are overall strengthened by the incorporation of new data, highlighting the […]

(Beyond Pesticides, March 23, 2026) After President Trump invoked the Defense Production Act of 1950 and issued an Executive Order (EO), Promoting the National Defense by Ensuring an Adequate Supply of Elemental Phosphorus and Glyphosate-Based Herbicides, U.S. Representatives Thomas Massie (R-KY) and Chellie Pingree (D-ME) stood up to say “no.” They introduced the No Immunity for Glyphosate Act (HR 7601) to undo the February 18 Executive Order, which is now being supported by a campaign to urge Congressional Representatives to cosponsor the bill.  With the EO’s declaration that contains no supporting documentation or findings, the U.S. government is granting Bayer/Monsanto immunity from lawsuits for adverse health effects or damage associated with the production, transportation, use, and disposal of the weed killer glyphosate. The executive order proclaims: “There is no direct one-for-one chemical alternative to glyphosate-based herbicides. Lack of access to glyphosate-based herbicides would critically jeopardize agricultural productivity, adding pressure to the domestic food system, and may result in a transition of cropland to other uses due to low productivity.  Given the profit margins growers currently face, any major restrictions in access to glyphosate-based herbicides would result in economic losses for growers and make it untenable for them to meet growing food and feed demands.” […]

(Beyond Pesticides, March 20, 2026) Biopesticides represent a kind of Utopian destination in the landscape of agricultural sustainability. If only they could ensure planetary harmony. A review of botanical biopesticides in the March 11 issue of Toxics raises important questions that require scrutiny and review under the pesticide registration process and when used in organic systems under the Organic Foods Production Act. The term biopesticide can be misleading, and any replacements for synthetic pesticides cannot be taken only on faith. As Beyond Pesticides has noted previously, the U.S. Environmental Protection Agency’s (EPA) definition of biopesticides—“derived from such natural materials as animals, plants, bacteria, and certain minerals”—is broad, vague, and used differently by different interests. EPA regulates biopesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) in three categories: Substances that interfere with mating, such as insect sex pheromones, as well as various scented plant extracts that attract insect pests to traps; Microbial pesticides consisting of a microorganism (e.g., a bacterium, fungus, virus, or protozoan) as the active ingredient; and Plant-Incorporated-Protectants (PIPs), pesticidal substances that plants are genetically engineered to produce. The review by Sandra Petrovic, PhD, and Andreja Leskovac, PhD, of the University of Belgrade, highlights the need not to […]

(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 17, 2026) An article in Microorganisms by researchers from the U.S., Israel, and Australia analyzes the adverse health and environmental effects of genetic engineering and genetically modified organisms (GMOs), specifically genetically modified microorganisms (GMMs). As the authors state, the prevalence of genetic engineering has “accelerated the creation and large-scale environmental release” of GMMs, which “present unique, long-term risks to human and environmental health.” One of the authors, André Leu, DSc, spoke at the first session of Beyond Pesticides’ National Forum Series: Forging a Future with Nature in 2023. (See recording here.) This review provides risk scenarios of GMMs, showing the threat to ecological systems, particularly within the soil, and human health. As GMMs are “biologically active, self-replicating entities capable of rapid mutation and global dispersal” they present greater risks, and current regulatory frameworks do not adequately assess their potential harm. Genetically altering microorganisms, the most complex and diverse systems in biology, and creating new gene combinations with unknown implications, “has the potential to disrupt the functions, diversity, interactions, and impacts of microbes and microbiomes,” the researchers note. They continue: “This puts human and environmental health at risk. Worst-case scenarios include the promotion of diseases, risks to species […]

(Beyond Pesticides, March 16, 2026) On the brink of the first genetically engineered (GE) wheat to be introduced into the U.S. market, after the U.S. Department of Agriculture (USDA) approved it in August, 2024, groups are calling on Congress to instruct USDA to prohibit HB4 wheat and instruct EPA to prohibit the use of glufosinate herbicides on wheat. The herbicide on which the crop is dependent, glufosinate, is a highly toxic herbicide banned in the European Union because of its links to reproductive and developmental harm. The drought- and herbicide-tolerant wheat, known as HB4 GMO wheat, follows a long line of genetically engineered crops that have been allowed to be grown in the U.S., with Roundup ReadyTM (glyphosate-tolerant) soybeans being among the first crops allowed in 1996. While the introduction of this technology promised to reduce pesticide use (herbicides are included under the definition of pesticide), the exact opposite occurred, with the skyrocketing of herbicide use. (See Daily News review of a study by Charles Benbrook, PhD, “Impacts of genetically engineered crops on pesticide use in the U.S.—the first sixteen years.”) The extraordinary increase in herbicide use associated with GE crops has been accompanied by an escalating increase in weed resistance […]

(Beyond Pesticides, March 11, 2026) The Monsanto Company, founded in 1901 and acquired by the multinational corporation Bayer AG in 2018, submitted its opening brief to the Supreme Court of the U.S. (SCOTUS) last month, seeking liability immunity from lawsuits filed by product users who have been harmed but not warned about potential product hazards. The question before SCOTUS is: “Whether the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S.C. 136 et seq., preempts a state-law failure-to-warn claim concerning a pesticide registered by the U.S. Environmental Protection Agency (EPA), where EPA has determined that a particular warning is not required and the warning cannot be added to a product label without EPA approval.” If successful, the Court would be overturning (reversing) its 2005 decision in Bates v. Dow Agrosciences, 544 U.S. 431, which upheld EPA and state registration of pesticides as a floor of protection, without releasing manufacturers of the responsibility to warn for potential harm that is not required by EPA. Pesticide manufacturers propose the text for their product labels and EPA ensures compliance with its minimum requirements, which does not preclude them from disclosing potential adverse effects they know of or should have known. The Missouri case before the Supreme Court, Durnell v. Monsanto, on the cancer causing effects of the weed killer glyphosate (RoundupTM) resulted in a jury verdict (in 2023) of $1.25 million and the total number of jury verdicts and settlements may amount to over $10 billion in liability if […]

(Beyond Pesticides, March 10, 2026) An article in the Journal of Agricultural and Food Chemistry identifies pesticides, often neglected, as a core factor in the spread of antibiotic resistance genes (ARGs) in agricultural environments. With antibiotic and antimicrobial resistance growing and infections becoming untreatable and deadly, the World Health Organization (WHO) has identified the problem as a “silent pandemic.” The authors, from Yangzhou University in China, highlight the persistence of both pesticide residues and ARGs throughout the environment, with both being found in water, soil, air, animal manure, and the human gut. “Existing studies have fully confirmed that pesticides are not isolated in the agricultural ecosystem but deeply participate in the proliferation and spread of ARGs through direct coselection, indirect induction of multiple resistances, and promotion of horizontal gene transfer, forming a combined pollution risk that superimposes on the traditional sources,” the authors note. The now well-known phenomenon of horizontal gene transfer—the movement of genes in bacteria from one bacterial species to another, which is facilitated by phages—means that ARGs in those (possibly harmless) bacteria can move to bacteria that cause disease in plants or humans. As stated in previous Daily News posts, pesticides by themselves are a grave threat […]

(Beyond Pesticides, March 9, 2026) Policy and toxicology are slated to collide as the U.S. Environmental Protection Agency (EPA) considers allowing the use of a PFAS pesticide by invoking an emergency waiver process in federal pesticide law. If authorized, EPA’s decision will permit the use of an unregistered pesticide under an emergency waiver provision—in this case an emergency caused by weed resistance to weed killers (herbicides) on the market. EPA is accepting public comments until March 16, 11:59pm EDT. Beyond Pesticides is urging the public to object to EPA approval by writing to EPA and Congress stating that herbicide resistance is not an emergency and PFAS chemicals must not be broadcast in the environment.  The pesticide that is being requested for use is a new not yet registered, herbicide tetflupyrolimet (TFP), which is a PFAS chemical according to the definition of the Organisation for Economic Co-operation and Development (OECD). The fact that the chemical is not registered by EPA means that it has not been reviewed in accordance with all the safety assessments reviewed under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The states applying for the exemptions under Section 18 of FIFRA—Missouri and Arkansas—claim that there is an emergency requiring the use of TFP because […]

(Beyond Pesticides, March 6, 2026) The Farm Bill—the Farm, Food, and National Security Act of 2026, H.R. 7567—reported out of the Agriculture Committee in the U.S. House of Representatives yesterday strips environmental and public health protections from pesticides, reversing over 90 years of environmental laws adopted by Congress to protect farmers, consumers, and the environment that stretch back to the first Farm Bill in 1933. The Committee rejected the Protect Our Health Amendment, sponsored by Rep. Chellie Pingree (D-ME), which would have ensured that the final bill maintain three core safeguards in current law: (i) Judicial review of chemical manufacturers‘ failure to warn about pesticide hazards; (ii) Democratic right of local governments in coordination with states to protect residents from pesticide use; and, (iii) Local site-specific action to ensure protection—the safety of air, water, and land from pesticides under numerous environmental statutes. All Republicans and one Democrat (Rep. Adam Gray, D-CA) on the Committee blocked the Pingree amendment. The Agriculture Committee bill adversely affects a wide range of social and conservation issues, including the protection of family farms, food security, environmental and public health, local and state authority, and judicial review, according to a cross-section of groups representing these interests.

(Beyond Pesticides, March 6, 2026) Does humanity want to live in a world without birds? This may seem like an extreme question, but a new study in Science concludes that, without changes in human behavior, just such a world may be on the horizon. This would be a tragedy of colossal proportions, not only for the ecosystem services birds provide, but for the meaning of human life and a healthy biosphere. The oldest human-made image of a bird is 40,000 years old. The new study, by Czech environmental scientist François Leroy, PhD, and two colleagues from The Ohio State University, measured local population abundances of 261 North American bird species between 1987 and 2021. They also measured the speeds at which the species’ populations rose or fell. The study was based on data from the North American Breeding Bird Survey, a program of the U.S. Geological Survey in coordination with the Canadian Wildlife Service. This survey involves direct observations of bird populations along roadsides during breeding season. The program was created in the mid-20th century in response to the severe mortalities associated with the use of DDT, highlighted by Rachel Carson in her seminal 1962 work, Silent Spring. In the […]

(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, March 2, 2026) In advance of deliberations on the Farm Bill tomorrow, March 3, in the Agriculture Committee of the U.S. House of Representatives, opposition to the GOP-proposed legislation has been widely expressed by farm, environmental, consumer, and social justice organizations. The bill, the Farm, Food, and National Security Act of 2026, H.R. 7567, is a dramatic departure from previous Farm Bills going back to the first one in 1933, which began a process of integrated policy to address family farmers’ sustainability, land conservation, energy, climate, and food security. Discarding the traditional bipartisan process used to draft the Farm Bill, the Republican leadership has instead proposed a measure that has garnered across-the-board disapproval, except from those representing the vested interests of chemical companies and agribusiness. In order to uphold fundamental protections from pesticides for farmers, consumers, and the environment, a campaign has emerged to urge U.S. Representatives to support Rep. Pingree’s Protect Our Health Amendment (removes Sections 10205-10207), move to strike Sections 10201-10204 and 102011, and support the No Immunity for Glyphosate Act provisions. Without a comprehensive overhaul, this campaign is urging a vote against the Farm Bill. Central to the GOP Farm Bill, released by the chair of the U.S. House Agriculture […]

(Beyond Pesticides, February 27, 2026) Researchers at Prairie View A&M University in Texas published in the journal Sustainability a study of organic agricultural systems from 1960 to 2021, concluding that “the outlook for U.S. organic fruit and vegetables is encouraging, supported by expanding consumer demand, government support, and improved conditions for international trade.” While delivering upbeat findings, including health benefits, the study identifies tremendous obstacles to entry into organic farming, including the limited support for alternative pest management and pest control systems in the United States in recent modern history, compared to the assistance provided for highly subsidized, petrochemical-dependent agricultural practices. Public health and environmental advocates continue to advocate for a wholesale transition to organic pest management, including calls for U.S. Representatives and Senators to cosponsor the Opportunities in Organic Act! Study Methodology, Background, and Findings The authors of this literature review arrived at the following conclusions on research trends for human health and environmental impacts of organic systems (for further analysis, the numbers below list citations from their report): “[O]rganic food has been documented to have higher antioxidant capacity, acidity, and phosphorus as well as lower levels of cadmium, pesticides, and other chemicals (18–22). Additionally, organic practices increase the […]

(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 23, 2026) Amid polarization in the U.S. Congress, key legal protections from pesticides will be revoked with passage of the GOP Farm Bill being debated March 3 in the House Agriculture Committee, despite a growing body of science that shows farmers, consumers, and the environment are facing escalating health and safety threats. In this context, grassroots efforts are underway asking Congressional representative to advocate for the removal of Farm Bill, Title X, Subtitle C, Part 1, which contains attacks on foundational protections from pesticides for farmers, consumers, and the environment—and vote against the Farm Bill if those provisions are not removed. As provisions in the GOP Farm Bill (Farm, Food, and National Security Act of 2026, H.R. 7567) that slash protections from pesticides go to a vote in the Agriculture Committee, health and environmental advocates are calling for committee members to remove the weakening section—Section X, Subtitle C, Part 1, on “Regulatory Reform.” At a time when documented adverse effects from pesticide exposure are skyrocketing and sustainable practices have become widely available, the bill is being characterized as a wish-list for the chemical industry. Recent studies demonstrating connections between prenatal and postnatal exposure to pesticides and severe consequences […]

(Beyond Pesticides, February 20, 2026) As pesticides’ adverse effects on human and ecosystem health stack up in the scientific literature, health and environmental groups are focused on striking an entire section of the Republican Farm Bill that will eliminate protections, which have been written into law for generations. The section is Section X, Subtitle C, Part 1 on “Regulatory Reform.” Threatened are policies intended to protect against the diseases and illnesses touching families and communities, including brain and nervous system disorders, birth abnormalities, cancer, developmental and learning disorders, immune and endocrine disruption, reproductive dysfunction, among others. Wildlife, including mammals, bees and other pollinators, fish and other aquatic organisms, birds, and the biota within soil, are adversely affected with reproductive, neurological, endocrine-disruptive, and developmental anomalies, and cancers. (See Pesticide-Induced Diseases Database.) With the urgent threat of a markup of the legislation scheduled to begin on March 3, attention shifted to a newly released Executive Order (EO) that could provide blanket legal protection for the manufacturer of the weed killer glyphosate, Bayer/Monsanto. By activating the Defense Production Act of 1950 and its immunity from lawsuits provision for glyphosate manufacturers, the administration could mandate production of glyphosate as a “national security” concern and provide […]

(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 17, 2026) The Ranking Member of the Agriculture Committee in the U.S. House of Representatives, Rep. Angie Craig (D-MN), issued a swift rebuke to the GOP 2026 Farm Bill text unveiled last Friday, saying it would be “’very difficult, if not impossible’ for her to back a GOP-led farm bill because it contains ‘poison pills’ and doesn’t do enough to aid struggling farmers,” according to Politico. She did not specifically point to the key controversial provisions that eliminate three 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 hazards, the democratic right of local governments in coordination with states to protect residents from pesticide use, and local site-specific action to ensure the safety of air, water, and land from pesticides. Beyond Pesticides responded with a nationwide action to Tell members of the U.S. House of Representatives to stop provisions in the Farm Bill that shield chemical companies from liability for the harm caused by their products, intrude on local communities’ democratic right to restrict pesticides, and eliminate pesticide restrictions governing clean water, environmental impacts, and endangered species; with a request to support […]

(Beyond Pesticides, February 16, 2026) The chair of the Agriculture Committee in the U.S. House of Representatives, in releasing the Republican 2026 Farm Bill draft last Friday afternoon, is challenging three 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 hazards, the democratic right of local governments in coordination with states to protect residents from pesticide use, and local site-specific action to ensure the safety of air, water, and land from pesticides. The draft Farm bill language in three separate sections: (i) prohibits lawsuits by farmers and consumers harmed by pesticides for which manufacturers failed to provide complete safety warnings (Section 10205); (ii) takes away the authority of local governments to protect residents and the local environment from pesticide use (Section 10206), and; (iii) repeals requirements in numerous federal statutes to protect against local pesticide contamination that could affect waterways, drinking water, federal projects, endangered species, migratory birds, and toxic waste (Section 10207). Beyond Pesticides responded with a nationwide action to Tell members of the U.S. House of Representatives to stop provisions in the Farm Bill that shield chemical companies from liability for the harm caused […]

(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 […]
