(Beyond Pesticides, October 9, 2025) The 42nd National Forum Series, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature—scheduled to begin on October 29, 2025, 1:00-3:30pm (Eastern time, US), will focus on aligning land management with nature in response to current chemical-intensive practices that pose a threat to health (see Pesticide-Induced Diseases Database), biodiversity, and climate. The virtual Forum is free to all participants. ➡️ Register here. The Call to the Forum, states: We are all affected by how land is managed, food is grown, and nature is protected. Different experiences and perspectives may bring us to care about health and the environment and the devastating adverse effects of pesticides and toxic substances. However, ensuring a livable future requires us to cultivate a collective concern about daily decisions on the management of our personal and community spaces, the practices used to grow the food we buy, and the care that we as a society give to complex and fragile interrelationships that sustain the natural world on which we depend. The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature challenges participants—as concerned families, community residents, purchasers of products, advocates for policy, decision makers, and workers—to think […]

(Beyond Pesticides, October 7, 2025) Published in Environment International, a study utilizing silicone wristbands provides a snapshot of chemical exposure in over 600 participants across 10 European countries. Using the wristbands as passive and noninvasive samplers, the researchers find that organic farmers’ wristbands contain lower pesticide levels than other groups, offering insight into the benefits of organic and disproportionate risks to farmers using chemical-intensive methods. The results further reveal prevalent environmental pesticide mixtures, in addition to highlighting exposure to current-use pesticides (CUPs) and legacy (banned) pesticides that occurs through multiple exposure routes to workers, residents, and consumers. “Our study offers a comprehensive analysis of non-dietary pesticide exposure patterns among various populations across the EU [European Union], underscoring its widespread prevalence and identifying significant occupational and residential predictors,” the authors explain. As pesticide exposure occurs through both dietary and nondietary routes, such as through dermal (skin) contact and inhalation of contaminated air, there “is a growing need for aggregated [total; combined] exposure estimates across occupationally and nonoccupationally exposed populations.” The study includes testing for 193 pesticides, both legacy pesticides and CUPs, captured in silicone wristbands worn by farmers, residents living close to treated fields (neighbors), and the general population (consumers) in […]

(Beyond Pesticides, October 1, 2025) A novel study in Scientific Reports combines computational analyses with toxicological data to identify pathways affected by exposure to the weed killer glyphosate. The analyses identify glyphosate targets that correlate with kidney injury and kidney cancer, revealing pathways with significant glyphosate-induced alterations, including the dysregulation of nitrogen metabolism that leads to ammonia accumulation and oxidative stress, both of which contribute to renal (kidney) damage and carcinogenesis (development of cancer). “This study provides a comprehensive investigation into the molecular mechanisms by which glyphosate may contribute to kidney injury and kidney cancer, employing an array of bioinformatics tools for target prediction, toxicity assessment, pathway enrichment analysis, molecular docking and molecular dynamics simulation,” the researchers state. The results of the analyses and simulations highlight the molecular mechanisms underlying glyphosate’s nephrotoxic (damaging to kidneys) and carcinogenic (cancer-causing) effects. Study Importance and Background Glyphosate, known as a broad-spectrum systemic herbicide, has been used for agricultural and nonagricultural purposes for decades and is the most extensively used herbicide worldwide. This widespread use is largely due to its application to genetically engineered, glyphosate-tolerant crops. Both glyphosate and its main metabolite (breakdown product), aminomethylphosphonic acid (AMPA), are detected in water, soil, and food, […]

(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. “We 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,” 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 Pesticides’ 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 23, 2025) A study published in European Journal of Agronomy, based on a 16-year, long-term experiment (LTE), finds that organic crops (cotton production with wheat and soybean rotations) in tropical climates are competitive with chemical-intensive (conventional) systems when evaluating systems’ resilience (to weather and insect resistance), input costs, and profitability. One of the underlying assumptions of continuous pesticide use is that they will continue to serve as effective weapons in the never-ending war against insects, weeds, and fungal diseases that threaten the economic viability and sustainability of the farming operations. While organic systems faced reduced yields due to pest pressures from pink bollworm infestations, their relative decline was much smaller than that of the chemical-intensive operations. This study’s findings indicate that a different direction is not only possible, but necessary, for the long-term financial viability of farms. Farmers understand that the health of the soil is a compounding investment that will help or hurt you depending on the actions taken yesterday, today, and tomorrow. The authors state in the study introduction that the long-term study is critical when studying organic productivity and profitability because short-term studies fail to capture. “Critical variables like soil health, pest dynamics, and […]

(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 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, “These findings highlight the mechanisms of fluorine-containing pesticide toxicity in earthworms, emphasizing their potential to disrupt soil ecosystems.” 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. “Data 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,” 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. “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 16, 2025) As reported in the Daily News on August 28, the U.S. Environmental Protection Agency (EPA) announced that it “will hold a public webinar [today], September 16, 2025, at 2:00 PM ET to provide information on the ecological runoff/erosion and spray drift mitigation measures that can be used to protect endangered species from pesticides.” This follows closely behind an earlier announcement of a newly released Pesticide App for Label Mitigations (PALM) mobile tool to assist in implementing these mitigation measures. Despite boasting that the PALM tool is a “one-stop shop” for farmers to use EPA’s mitigation menu, which the agency claims helps to protect nontarget species, environmental critics say that self-directed mitigation without a rigorous reporting and enforcement apparatus fails to meet the level of protection that is necessary under the Endangered Species Act (ESA). As Beyond Pesticides has often reported, mitigation measures are not enforced through recordkeeping, inspections, and certification, and require no accountability from farmers and pesticide applicators. At the same time, EPA assumes compliance with mitigation measures as the basis for meeting statutory standards of reasonable risk from harmful chemicals, despite documented health and environmental harm. As a Daily News article earlier this […]

(Beyond Pesticides, September 15, 2025) With residues of the widely used weed killer glyphosate (Roundupᵀᴹ) in the food supply long documented, scientific attention has turned to the synergistic effects of the weedkiller— a magnified effect greater than the individual chemical effects added together. The authors of an article in World’s Poultry Science Journal write, “The synergistic toxic effects of commercial glyphosate formulations and their bioaccumulation in animal tissues are often overlooked in current safety assessments.” Following up on a previous action, Beyond Pesticides is telling Congress and the U.S. Environmental Protection Agency (EPA) that the agency must consider the effects of pesticides in the context in which they are used and promote the organic alternative. Glyphosate residues in animal feed, as well as in water and through other exposure routes from food generally and residential areas, pose risks to both animal and human health, as these residues can bioaccumulate. As previously examined by Beyond Pesticides, the effects of pesticides are not limited to the crops to which they are applied. Synergistic effects of multiple chemical exposures are the rule, rather than the exception. With poultry, the herbicide enters the production system through residues in genetically engineered feed. An earlier article in Scientific Reports concludes that glyphosate’s […]

(Beyond Pesticides, September 12, 2025) A team of Argentinian researchers conducted a study published in Environmental Toxicology and Pharmacology of the combined effects of the herbicide glyphosate and the pyrethroid insecticide cypermethrin. The researchers observed significantly higher apoptosis in cells exposed to the mixtures than to the individual pesticides—a synergistic response. Apoptosis, also known as programmed cell death, is a standard way that tissues handle damaged cells to remove threats to their function. The researchers sought to investigate the cellular toxicity of each chemical, individually and in combination, and assessed whether the effects of the mixture were additive or synergistic. Additive effects occur when two individual chemicals amplify the same sort of response, often because the chemicals have similar structures. Synergism can occur when chemicals have different mechanisms of action but work together to create more powerful effects. Mixtures of pesticides are the least-studied area of research conducted for regulatory purposes. While regulators provide instructions to applicators regarding which pesticides can be applied together and combined in tank mixtures, there is no control over how pesticides travel through the environment once applied, as they flow through the air as spray drift, lodge in soils and water, and are incorporated into […]

(Beyond Pesticides, September 10, 2025) After being criticized by the chemical industry and allied agribusiness and service industry groups on the Make America Healthy Again (MAHA) report in May, the strategy document, released yesterday, has tamped down efforts to reform government programs that regulate pesticides. There are no specific recommendations on improving the regulation of pesticides. Rather, the strategy appears to embrace business-as-usual and could even ramp up government efforts to tout the need for pesticides and claims that current regulatory reviews are effective and comprehensive. In a section of the strategy entitled “Increasing Public Awareness and Knowledge,” the document says: “EPA, partnering with food and agricultural stakeholders, will work to ensure that the public has awareness and confidence in EPA’s pesticide robust review procedures and how that relates to the limiting of risk for users and the general public and informs continual improvement.” This is at odds with the earlier MAHA assessment report which identified pesticides as substances of concern that, citing deficiencies in chemical reviews, “may be neglecting potential synergistic effects and cumulative burdens, thereby missing opportunities to translate cumulative risk assessment into the clinical environment in meaningful ways.” While the earlier report, Make Our Children Healthy Again: Assessment, […]

(Beyond Pesticides, September 8, 2025) Beyond Pesticides today called on Congress to require the U.S. Environmental Protection Agency (EPA) to incorporate real world science into its evaluation of pesticide safety calculations by recognizing that daily exposure involves multiple chemicals and synergistic interactions— a magnified effect greater than the individual chemical effects added together. The organization cites numerous scientific studies that call public attention to this issue; that a realistic assessment of the human and environmental harm potentially caused by pesticides cannot be evaluated based on single-chemical, single-species tests. Given the numerous complexities associated with this type of assessment, the group points to organic land management in agriculture and residential areas as a more cost-effective approach, sending this message to Congress: EPA must consider the effects of pesticides in the context in which they are used and with reference to the organic alternative. A recent study, covered by Beyond Pesticides in its Daily News, found that the presence of Varroa mites in combination with the neonicotinoid insecticide imidacloprid increases the risk of bee mortality and disrupts the larval gut microbiome. The study found synergy (a greater combined effect) between Varroa destructor, a parasitic mite that attacks and feeds on honey bees, and imidacloprid. The findings were published last […]

(Beyond Pesticides, September 5, 2025) A study in Journal of Agricultural and Food Chemistry finds permethrin, a commonly used synthetic pyrethroid insecticide, to be disruptive to the gut microbiome, altering microbiota and leading to increased formation of fat cells (adipogenesis) and metabolic disorders. With an aim to “comprehensively elucidate the effects of permethrin on gut microbiota, lipogenesis, and the associated molecular mechanisms,” the study explores the adverse effects of permethrin exposure in adult mice through multiple experiments. “Our study provides the first in vivo [in a living organism] evidence suggesting a potentially causal relationship between permethrin exposure and the development of obesity, potentially mediated by specific gut microbiota-derived metabolites,” the researchers explain. They continue, “Notably, this work is the first to define a distinct microbiota−metabolite−host axis as a critical mediator of environmental toxicant-induced metabolic dysfunction.” Permethrin is widely used as an insecticide on crops, such as cotton, corn, and wheat, as well as on livestock, in indoor and outdoor areas, and for treating lice and scabies. Mosquito abatement programs often utilize permethrin, further adding to the various exposure routes of this neurotoxic chemical. (See additional uses and health effects of permethrin in Beyond Pesticides’ Gateway on Pesticide Hazards and Safe […]

(Beyond Pesticides, September 4, 2025) A review of agricultural neonicotinoid insecticide regulations, published in Pest Management Science, evaluates the varied approaches being taken for bans and exemption-based restrictions in the European Union (EU), Canada, and the United States (U.S.). Despite an ever-growing and overwhelming body of science linking neonicotinoids (neonics) to adverse effects on pollinators and other nontarget species, the regulations fall short in protecting the environment and wildlife. The review, with the history and current status of neonics, lends further support for a full transition to organic agriculture and land management that removes neonicotinoid exposure routes and subsequent health threats. With the application of this widely used class of neurotoxic system insecticides increasing, so too has the concern over the long-term chronic effects on pollinators and other species from exposure. This concern, backed by scientific literature, has “led to increased governmental regulations since the mid-2010s, particularly in agricultural settings,” state the authors from Iowa State University and Washington State University. They continue, “These regulations have varied in terms of approach, geography, and timeline, starting with a ban implemented by the European Union (EU) and evolving into exemption-based regulations across two Canadian provinces and five U.S. states as of this […]

(Beyond Pesticides, September 3, 2025) A study in Environmental Entomology shows that habitat and open space near agricultural fields become a killing field of pesticides, threatening biodiversity due to contamination from toxic drift. The study detected 42 pesticides, including several neonicotinoids, which are among the most lethal threats to pollinators. The research reveals the complexity of pesticide flow through the environment and the inadequacy of current methods of protecting nontarget organisms, including honey bees, bumblebees, and hundreds of other species of native bees worldwide. Their catastrophic declines is tied to pesticides in large part and highlights the inadequacy of current pesticide reduction strategies, such as integrated pest management (IPM) and now other loosely defined concepts like “regenerative,” in an attempt to protect the environment and nontarget organisms in chemical-dependent land management and agriculture. (See What the Science Shows on Biodiversity.) The researchers on the study, from the U.S. Department of Agriculture, Cornell University and Michigan State University, put silicone bands on fence posts in open areas adjacent to highbush blueberry fields on 15 farms in western Michigan. Silicone takes up chemicals in the atmosphere which can then be extracted and analyzed. The fence posts were placed at seven intervals ranging […]

(Beyond Pesticides, August 29 – September 1, 2025) It is recognized, especially on Labor Day, that the adverse effects of pesticides, with the preponderance of science accumulating every day, put workers (those who handle pesticides and are exposed through inhalation and skin absorption) at elevated risk above rates in the general population. The harm to workers is exacerbated by additional and cumulative exposure to pesticides that occurs through daily life—residues in food, water, and landscapes. Beyond Pesticides is reaching out to its network and urging people and organizations to: On Labor Day, ask your Mayor to lead a transition to practices and product procurement that protect workers with criteria that meet organic standards in landscaping and food purchasing. With the dismantling of federal government programs charged with establishing protections and ramping up deregulation of the chemical, agribusiness, and allied industries, safety strategies for workers who are the backbone of society fall to local governments and people whose decisions should not result in hazardous worker exposure to toxic pesticides. Municipality and school district purchasing of food grown with toxic chemicals results in poisoning of farmworkers, their children, and their communities. Purchasing and applying toxic lawn care products or contract services results in […]

(Beyond Pesticides, August 28, 2025) The U.S. Environmental Protection Agency (EPA) on August 12, 2025, released a statement, “EPA Announces Action to Protect Endangered Species from Insecticide Methomyl,” in which the agency announced label changes for methomyl, a carbamate insecticide, with mitigation measures that are being criticized as allowing great risks to biodiversity and human health. The label changes, following the National Marine Fisheries Service’s (NMFS) final biological opinion issued on January 1, 2024, actually establish mitigation measures to be determined by applicators using the Bulletins Live! Two website prior to use. EPA claims that this grower determined action will meet the standards of the Endangered Species Act (ESA) by “reduc[ing] runoff and spray drift from treated areas into species’ habitats.” However, the process does not include monitoring and oversight to determine whether the rigorous standards of ESA are being met. The agency says that mitigation tracking is “at the field or farm level,” but it is not required to be submitted to the agency. EPA announced on August 20 that it is holding a 90-minute public webinar on September 16, 2025, at 2:00 PM ET to provide information on the ecological runoff/erosion and spray drift mitigation measures that can […]

(Beyond Pesticides, August 19, 2025) A new study from Argentina highlights the importance of applying the concept of the exposome (total exposures over lifetime) as a scientific framework, the value of biomonitoring, and findings of adverse pregnancy outcomes. The study documents the presence and effects of pesticides on maternal and fetal health during pregnancy. The results show that pregnant Argentine women are exposed to dozens of pesticides, and that certain mixtures of these chemicals are associated with harm to pregnancy outcomes, especially among rural women. The exposome, the authors write, comprises the “non-genetic factors that may be involved in the development or aggravation of human disease. The prenatal exposome includes all environmental chemicals that the mother is exposed to during pregnancy (maternal exposome) and those chemicals that reach the placenta and fetus from the maternal circulation (fetal exposome).” The authors emphasize that understanding the exposome almost by definition requires studying mixtures of environmental chemicals rather than analyzing the effects of each in isolation. The second important aspect of the study is its use of biomonitoring. The researchers analyzed urine samples from 90 pregnant women in various gestational stages from rural and urban regions of Argentina. The researchers also collected demographic […]

(Beyond Pesticides, August 15, 2025) In analyzing the data present in an article in Data in Brief, concerning levels of pesticide biomarkers are present in the urine of adolescents and young adults that are linked to numerous health implications. The biomonitoring data, collected at two time points from participants in a longitudinal cohort study in the agricultural county of Pedro Moncayo, Ecuador, encompasses a total of 23 compounds used as herbicides, insecticides, and fungicides and their associated metabolites (breakdown products), which include organophosphates, pyrethroids, and neonicotinoids. The results highlight the disproportionate risks to a Latin American population that occur as a result of living in areas with heavy chemical-intensive agriculture. “This article presents urinary pesticide metabolite concentrations for 665 participants in the ‘Study of Secondary Exposure to Pesticides among Children, Adolescents, and Adults’ (ESPINA), which were collected during two follow-up assessments,” the authors describe. The first sampling period from July to October 2016, referred to as Follow-up Year [FUY]-8b, includes 529 of the participants, while the second sampling period from July to September 2022 (FUY-14a) includes 505 of the participants. All participants are within the agricultural community of Pedro Moncayo. As the authors note, “The ESPINA study aimed to include […]

(Beyond Pesticides, August 7, 2025) The novel study published in Arthritis & Rheumatology is the largest investigation of rheumatoid arthritis (RA) in women to date, finding evidence of heightened risks when exposed to insecticides through data collected from over 400 eligible women in the Agricultural Health Study (AHS). AHS participants include a cohort of thousands of licensed pesticide applicators and their spouses from Iowa and North Carolina, with this particular study as the first to consider the link between pesticide exposure and RA as it affects women’s health. “Growing evidence suggests farming and agricultural pesticide use may be associated with rheumatoid arthritis (RA), but few studies have examined specific pesticides and RA among farm women, who may personally use pesticides or be indirectly exposed,” the study authors explain. The findings reveal that organochlorine insecticides that continue to persist in the environment, as well as organophosphate and synthetic pyrethroid pesticides used in public health or residential settings, correlate with RA diagnoses in women. As shared in previous Daily News, for the most part organochlorine pesticides, including dichlorodiphenyltrichloroethane (DDT), are no longer used worldwide, but the legacy of their poisoning and contamination persists. These compounds are primarily made up of chlorine atoms, […]

(Beyond Pesticides, August 5, 2025) A biomonitoring study in Environmental Geochemistry and Health, focused on small-scale farms in Pahang, Malaysia, analyzes levels of essential and toxic elements in hair and nail samples from chemical-intensive and organic farmers. While the results reveal elements that correlate with specific farming practices, common elements to both chemical-intensive and organic farming highlight the role of pesticide drift in off-target contamination, diminishing some of the benefits of organic agriculture. The persistent and pervasive nature of many pesticide products results in exposure patterns, in addition to direct occupational exposure on chemical-intensive conventional farms, that trespass onto organically managed land and threaten health and the environment—raising policy and practice issues needed to safeguard the public. Cameron Highlands in Malaysia is a region known for intensive pesticide use as well as for its vegetable and flower farming, where both conventional and organic agriculture exist in close proximity. “Despite different agricultural approaches, both groups remain at risk of environmental exposure due to long-term pesticide application in the region,” the authors write. They continue, “While organic farming practices may reduce direct exposure to synthetic agrochemicals, the risk of cross-contamination from surrounding conventional farms remains a concern due to environmental dispersion through […]

(Beyond Pesticides, August 4, 2025) Comments on EPA proposal to bring back controversial use of herbicide dicamba due by Saturday, September 6, 2025, at 11:59 PM ET. With more than 90 percent of soybeans (also corn and the most common species of cotton) planted in varieties genetically engineered to be herbicide-tolerant, the agrichemical industry and industrial agribusiness are lining up to bring back agricultural spraying of the controversial weed killer dicamba—linked to crop damage associated with the chemical’s drifting off the target farms. The courts in 2020 and 2024 vacated EPA’s registration authorizing “over-the-top” (OTT) spraying of dicamba, leading to these uses being stopped in the 2025 growing season. (See Daily News.) Genetically engineered crops, widely adopted in 1996 with Monsanto’s glyphosate-tolerant (Roundup Ready) soybean seeds and plants, have been plagued by weed resistance to the weed killers, movement of genetic material, chemical drift, and health and environmental hazards associated with pesticide exposure. Despite the problems and escalating herbicide use in chemical-dependent no-till (no tillage) agriculture, regulators at the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Agriculture (USDA) have facilitated the astronomical growth of a genetically engineered food system. The industry makes the environmental argument that less […]
