(Beyond Pesticides, November 13, 2024) A study in Chemosphere, conducted by researchers from the Institute of Biochemistry and Molecular Biology in Germany, reveals the varied lethal and sublethal effects of different glyphosate mixtures through tests on the South African clawed frog, Xenopus laevis (X. laevis). After exposing embryos to four glyphosate formulations, mortality, morphological defects, altered heartbeat rate, and impaired heart-specific gene expression are observed. Glyphosate, an herbicide and popular weed killer in many Roundup® products, is one of the most commonly detected pesticides in waterbodies worldwide, threatening aquatic organisms and overall biodiversity. This study investigates the effects of Glyphosat TF, Durano TF, Helosate 450 TF, and Kyleo, four formulations containing glyphosate, as compared to the effects of pure glyphosate on embryonic development in amphibians. The formulations consist of varying concentrations of the active ingredient glyphosate, as well as other active and inert ingredients. The authors share that, “Glyphosat TF contains 34% glyphosate and 10–20% d-glucopyranose, while Durano contains 39–44% glyphosate and 1–5% N–N-dimethyl-C12-C14-(even numbered)-alkyl-1-amines. In Helosate most of the ingredients are listed – 50–70% glyphosate, 1–10% isopropylamine, 1–3% lauryl dimethyl betaine, 0.25–1% dodecyl dimethylamine. Kyleo only lists the active ingredients glyphosate (27.9%) and 2,4-D (32%).” 2-cell stage embryos (early […]

(Beyond Pesticides, August 30, 2024) There is no more compelling reason to embrace a precautionary pesticide poisoning standard this Labor Day than the need to protect workers. In fact, the Occupational Safety and Health Administration (OSHA) says on its website, Transitioning to Safer Chemicals, that the best way to protect workers is to  “eliminate or reduce hazardous chemicals at the source.” While some try to employ product substitution with “safer” chemicals, Beyond Pesticides urges decision makers to embrace alternative systems, such as organic management systems, that embrace management techniques to meet disease and infestation management goals and use only organic compatible substances. According to OSHA: “In chemical management, [the industrial hygiene principle, known as the hierarchy of controls] guides employers and workers to eliminate or reduce hazardous chemicals at the source by substituting them with safer alternatives. Unlike traditional engineering controls, administrative controls, work practice controls, or personal protective equipment, these strategies can completely eliminate exposure to hazardous chemicals, reduce the potential for chemical accidents, reduce disposal costs, and remove concerns regarding worker compliance and equipment maintenance.” A look through the state and federal databases that track occupational pesticide poisoning for both acute (immediate short-term) and chronic (long-term) pesticide effects […]

(Beyond Pesticides, July 25, 2024) On July 10, the Oregon Court of Appeals ruled that the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) does not preempt pesticide exposure victims’ state law claims against pesticide manufacturers, based on reporting from The New Lede. This decision builds on years of judicial precedent from the Supreme Court of the United States (SCOTUS) that protects individuals’ right to use failure-to-warn claims against producers of toxic pesticides, including Bayer-Monsanto. The importance of judicial review is critical to protecting the public against public health impacts of toxic pesticide use in the context of last month’s SCOTUS decision ending Chevron Doctrine, and with it the end of deferring to federal regulatory agencies on ambiguities in statutory mandates. A growing coalition of environmental and public health advocates, organic farmers, trial attorneys, farmworkers, and physicians are united in pushing back against a concerted effort by industry and its allies to attack victims’ ability to sue under “failure-to-warn” through the Farm Bill, state legislatures, and the proposed federal budget for Fiscal Year 2025. Oregon Court of Appeals In 2022, a local trial court in Oregon ruled in favor of Monsanto on a lawsuit initiated by Jackson County residents Larry and […]

(Beyond Pesticides, May 23, 2024)  A study recently published in the journal Nature compared the impact of organic and conventional food production using eight environmental health indicators and found that organic food has a significantly lower environmental impact than conventional food production for six of the eight indicators, including a lower potential for contributing to acidification of the environment, energy use, and biodiversity loss. For the analysis, scientists reviewed 100 different “life cycle assessments” (LCA) of organic and conventionally grown food products from cradle-to-farm gate.    LCA is a commonly used methodology to estimate food production system impacts on the environment through resource depletion and pollutant emissions. The results—that organic food production is less impactful on the environment—add to the robust body of research that underscores the importance of organic farming to the development of a sustainable global food system while addressing climate change. Beyond Pesticides has long argued that one of the most powerful tools in fighting global warming is organic agriculture, as it sequesters atmospheric carbon, eliminates the use of fossil fuel-based synthetic fertilizers and synthetic pesticides, and provides environmental and human health benefits. This study and most of the 100 studies it evaluates, do not recognize that conventional […]

(Beyond Pesticides, May 14, 2024) As research continues to emerge on the value of organic farming, U.S. Congress debates its future as Farm Bill negotiations have been stalled for months. Recent studies published within the past few months show the significance of organic agriculture’s support of fungal and microbial life, which is essential to soil health. Meanwhile, last week the Democrat-led Senate and Republican-led House of Representatives presented their respective visions to amend the 2024 Farm Bill. The office of U.S. Senator Debbie Stabenow (D-MI), chair of the Senate Agriculture Committee, released an initial Senate framework for the (now 2024) Farm Bill. At the same time, U.S. Representative Glenn Thompson (R-PA), chair of the House Agriculture Committee, released an outline of the House version, then followed up with more details. While the Senate Democratic proposal includes more robust support for expanding and strengthening organic product supply chains and domestic production, the House Republican support for organic land management principles and practices demonstrates that the Farm Bill could recognize, across the political spectrum, its economic, ecological, and public health benefits in the United States. Despite this, a growing coalition of advocates is alerting the public and members of Congress that the […]

(Beyond Pesticides, April 8, 2024) When Mexico in 2020 decided to protect its traditional varieties of corn for reasons of health, safety, environmental protection, and food sovereignty with the banning of the importation of genetically engineered (GE or GM-genetically modified) corn by 2024, the powerful biotech industry and the U.S. government began a concerted campaign to stop the country’s efforts. With the opposition spearheaded by BIO, “the world’s largest trade association representing biotechnology companies, academic institutions, state biotechnology centers and related organizations across the United States and in more than 30 other nations” (as described in its March 15 press release), including companies like Bayer/Monsanto, the U.S government is calling Mexico’s action a trade barrier. The U.S. is invoking the U.S.-Mexico-Canada Agreement (USMCA), the trade agreement that replaced the North America Free Trade Agreement (NAFTA) in 2020. This is just one of the latest examples of corporate power reigning over U.S. environmental and economic policies. Mexico has already announced a delay in the planned April 1 ban on the importation, production, distribution, and use of glyphosate. Interestingly, this is all happening despite reports that the Biden administration is seeking to “tackle corporate abuses,” which is apparently limited  to tax reform and […]

(Beyond Pesticides, April 2, 2024) There is a nascent capital investment effort in the transition to certified organic agriculture beginning to take hold across the U.S., something advocates say is critically needed to meet the current and escalating existential health threats, biodiversity decline, and climate emergency. Mad Agriculture has received early commitments from the Rockefeller Foundation, Builders Vision, and nearly a dozen other investors to contribute to the $50 million Perennial Fund II (PFII), to advance the growth of “regenerative organic” agriculture. Forbes is reporting that PFII’s primary objective is to jumpstart the organic land transition, given that this slice of U.S. agriculture makes up less than one percent of total farmland in the country relative to the European Union’s nearly 10 percent of total farmland. “We commend the work of Mad Agriculture in harnessing the spirit of organic agriculture and mobilizing the private sector to invest in farmers who engage in regenerative organic agricultural practices,” said Max Sano, organic program associate at Beyond Pesticides. In Rockefeller Foundation’s press release announcing their early commitment, Mad Capital co-founder Brandon Welch spoke on their vision: “We are aiming to build a bridge between two distant worlds that need one another to transition […]

(Beyond Pesticides, March 26, 2024) The authors of a case study in Canale D’Aiedda, Taranto, Italy, published in Scientific Reports, conclude that, “[T]he results of monitoring and modeling activities revealed a chronic risk associated with the presence of Cu [copper] from November to April in several river reaches and acute risk associated to the presence of glyphosate in several reaches mainly in the wet season.”  According to the authors, “The most important factor influencing the chronic risk for Cu were the combination of two factors: the high surface runoff and the Cu applications. The most important factor influencing the glyphosate peaks of concentration is the streamflow.” The authors of the study measure the flow of pesticide concentrations through the soil and water assessment tool (SWAT). The ecotoxicological data was collected at two stations in Germany that flow into Italy, within the Canale d’Aiedda basin. The streamflow was monitored between August 2017 and December 2019. Out of hundreds of pesticides and six metabolities investigated in this study, “only traces of copper and glyphosate were found.” The authors continue, “The banks and the bed of the river system are almost all covered by concrete. The hydrological regime is natural and intermittent in […]

(Beyond Pesticides, March 20, 2024) A report by CBAN unpacks the ecosystem and wildlife health impacts of genetically engineered (GE) corn in the context of Mexico’s 2023 decision to stop its importation into the country. The phase out of genetically modified (GM) corn imports into Mexico was immediately challenged by the U.S. and Canadian governments as a trade violation under the 2020 U.S.-Mexico-Canada Agreement (USMCA), which replaced the North American Free Trade Agreement (NAFTA) as the primary vehicle for North American trade policy. In August 2023, the U.S. Trade Representative set up a dispute settlement panel under USMCA to stop Mexico from going forward with its ban. There has been no public update from the Office of the U.S. Trade Representative as of this writing. The CBAN report highlights the scientific rationale underpinning Mexico’s decision to “safeguard the integrity of native corn from GM contamination and to protect human health” with this ban. In 2020, Mexico announced a four-year phase-out of the weed killer glyphosate, which along with other petrochemical herbicides is integral to GM corn production. When Mexico’s Minister of the Environment announced the phase-out, he said it is part of an effort to transform the country’s food system […]

(Beyond Pesticides, March 15, 2024) Toxic pesticides harm all beings and ecosystems, including coral reefs. Large benthic foraminifera (LBF) are single-celled organisms found on reefs that face adverse metabolic impacts after exposure to the weed killer glyphosate and insecticide imidacloprid, according to a study published in Marine Pollution Bulletin. The study found that “even the lowest doses of the fungicide and herbicide caused irreparable damage to the foraminifera and their symbionts.” Beyond Pesticides reiterates our mission of banning toxic petrochemical pesticides by 2032 and that this goal applies to land and water exposure to pesticides. LBFs are typically used as bioindicators for coral health because they are found in substantial quantities and gathering data is not intrusive or damaging to reef health. Researchers in this study screened three different herbicides (one insecticide, one fungicide, and one herbicide) at three different concentration levels. The experiments were performed in six well-samples, each with 10mL of filtered artificial seawater and a singular LBF. The control plates are artificial seawater and the experimental plates include artificial seawater with the addition of three pesticides (imidacloprid, glyphosate, and tebuconazole). Each pesticide was applied at low, medium, and high doses to measure the direct impacts of each […]

(Beyond Pesticides, March 7, 2024) As the threats to health, biodiversity, and climate converge in agricultural policy and practices, the question of defining the fundamental changes necessary to reverse these existential crises takes on life-sustaining importance. Despite the existence of an organic community with governing stakeholders (farmers, consumers, conservationists, retailers, processors, inspectors, and scientists) that has evolved over at least seven decades and is codified in the Organic Foods Production Act (OFPA) of 1990, the term “regenerative” is now increasingly being advanced as a loosely defined alternative to the organic standard and label, which is transparent, defined, certified, enforced, and subject to public input. The publication AgFunderNews (AFN) last month published its updated “2024 list of agrifood corporates making regenerative agriculture commitments,” a who’s who of the largest food and agribusiness corporations worldwide. The list includes companies such as ADM, Cargill, Danone, General Mills, Tyson, Unilever, Walmart, and more with commitments to millions of acres in their supply chain practicing “regenerative” agriculture with target dates ranging from 2024 to 2050. The AFN author reporting on the “regenerative” trend states, “[O]ne big challenge is that ‘regenerative agriculture’ still has no set definition. While that still holds true, the bigger observation in […]

(Beyond Pesticides, February 23, 2024) The latest string of billion-dollar plaintiff judgments against Bayer/Monsanto, the maker of Roundup™ with active ingredient glyphosate, does not yet signal a capitulation by Bayer or a win for public health or the environment in the United States. A jury award of $2.25 billion, the largest to-date, was handed down in Philadelphia in January. As Beyond Pesticides reported previously, Monsanto has a long history of challenging scientific findings on Roundup/glyphosate and evidence of harm to human health, the environment, and crops themselves (see resistant super weeds here and here), as it seeks to avoid liability claims by those suffering from cancer.  Bayer Looking to State Legislatures for Protection from Lawsuits  As result of its failure in quash lawsuits, Bayer has moved its case to state legislatures, where it is seeking the adoption of statutes that preempt liability claims by damaged parties.  As reported by Beyond Pesticides, a rash of state legislation has been introduced in Idaho, Iowa, Missouri, and Florida, which would block plaintiff liability claims when pesticide products, like Roundup, cause harm. The chemical industry pushes the notion that the registration of its pesticide products with the U.S. Environmental Protection Agency (EPA) is a […]

(Beyond Pesticides, February 8, 2024) A study published in Environmental Research finds an association between adverse neurodevelopment (brain function and development) among infants and exposure to the herbicide glyphosate during pregnancy (gestational). Moreover, neurodevelopment becomes more pronounced at 24 months or two years. The increasing prevalence of neurodevelopmental disorders (NDDs) in the United States has raised concerns about the impact of toxic exposures on child development. Given the disproportionate exposure burden in the U.S., children from marginalized groups and low-income families are more likely to face a variety of harmful threats that can negatively affect childhood development. These disparities are linked to neurodevelopmental disorders. NDDs are defined as conditions related to the functioning of the nervous system and the brain, including attention-deficit/hyperactivity disorder (ADHD), autism, learning difficulties, intellectual disability (cognitive impairment), conduct disorders, cerebral palsy, and challenges related to vision and hearing. Therefore, the study notes, “Given glyphosate’s wide usage, further investigation into the impact of gestational glyphosate exposure on neurodevelopment is warranted.” The study includes mother-child pairs in a Puerto Rican birth cohort called PROTECT-CRECE, which measures urinary glyphosate and aminomethylphosphonic acid (AMPA; a metabolite [breakdown product]) of glyphosate) levels from mother and child for analysis. The study collected samples from the mother up to […]

(Beyond Pesticides, February 2, 2024) Last March, the European Union (EU) Parliament passed a measure to prevent greenwashing in the EU. As public concern about both human and ecosystem health rises, so does greenwashing—corporate efforts to mislead the public with label and marketing language for products and services that is outright dishonest or contains misrepresentations. And so, there has been an explosion of products or practices that are characterized in the market as “eco-friendly,” “green,” “carbon-neutral,” “regenerative,” “sustainable,” “natural,” and “safe”—all with a lack of uniform definition, compliance criteria, and enforcement. To the contrary, in crop/plant production and processing, “organic” does have a legal definition, subject to public review, certification, and enforcement. However, with greenwashing, many corporations aggressively try to gain a share of the $60 billion organic food market and nearly $22 billion organic personal care product market in the U.S. According to ESG Today, the new law passed by the EU Parliament arose because a European Commission-sponsored study found that more than half of green claims are vague or misleading, and another 40% could produce no supporting evidence at all. EU member states have two years to incorporate the measure into their own laws. There is already an EU […]

(Beyond Pesticides, February 1, 2024) A study published in Science of The Total Environment finds an insecticide ban would be economically beneficial in preventing Parkinson’s disease (PD). Despite differing pesticide exposure scenarios, PD risk lowers without pesticide exposure, especially insecticides that elicit neurotoxicity. In fact, a study published in 2023 notes high exposure to household pesticides, which are primarily insecticides, increases the risk of developing Parkinson’s disease (PD) two-fold. There is a multitude of epidemiologic research on Parkinson’s disease demonstrating several risk factors, including specific genetic mutations and external/environmental triggers (e.g., pesticide use, pollutant exposure, etc.). However, several studies find exposure to chemical toxicants, like pesticides, has neurotoxic effects or exacerbates preexisting chemical damage to the nervous system. Studies suggest neurological damage from oxidative stress, cell dysfunction, and synapse impairment, among others, can increase the incidence of PD following pesticide exposure. Despite the widespread commercialized use of household pesticides among the general population, few epidemiologic studies examine the influence household pesticides, mainly insecticides or disinfectants, have on the risk of PD. Additionally, many studies demonstrate the association between PD onset and occupational (work-related) pesticide exposure patterns. Parkinson’s disease is the second most common neurodegenerative disease, with at least one million Americans […]

(Beyond Pesticides, January 19, 2024) A study published in Environmental Health Perspective is one of the first to indicate a link between exposure to the herbicides 2,4-D and glyphosate and the impairment of behavioral performance (i.e., attention/inhibitory control, memory/learning, language, visuospatial processing, and social perception). These adverse effects associated with the neurotoxic impacts of pesticides on behavior have been previously documented. For example, a study in August 2023 finds oral intake (e.g., eating contaminated foods), inhalation, and dermal exposure to glyphosate lowered cognitive function scores, increased the likelihood of severe depressive symptoms, and impaired auditory (hearing) function. Although previous studies find neurotoxic effects from exposure to these herbicides, very few until now have evaluated how this neurotoxic exposure impacts neurotypical behavior among youth (children and teenagers). The ubiquitous use of glyphosate and 2,4-D use in agriculture—which leaves residues of the toxic chemicals in food and in public areas (e.g., parks and walkways) creates a creates a significant risk for exposure. Glyphosate is already implicated in or proven to lead to the development of numerous health anomalies, including cancer, while 2,4-D also has a range of potential hazards, including cancer. Therefore, studies like this help local and government officials make holistic decisions regarding the use […]

(Beyond Pesticides, November 13, 2023) The news of a federal Appeals Court’s reversal of a U.S. Environmental Protection Agency (EPA) decision in early November calls into question the value of the basic structures, processes, and authorities of pesticide law that the public has been told are protective of health and the environment. After decades of review and litigation, this reversal, especially on a highly neurotoxic insecticide like chlorpyrifos, identifies a fundamentally flawed system that does not protect the health of people, in this case, children’s brains. >>Tell your governor and mayor to adopt policies that support organic land management.  It was EPA’s finding that chlorpyrifos was destructive of the nervous system, particularly in children, and the functioning of the brain that led to an EPA-negotiated chemical company (Corteva/Dow Chemical) settlement in 1999 (took effect in 2000) that removed residential uses of chlorpyrifos from the market. The 2020 EPA decision, 21 years later, to stop agricultural uses followed another Appeals Court decision, departing from the agency’s usually long drawn-out negotiations that ultimately compromise health and the environment. EPA banned agricultural uses of chlorpyrifos in 2016 in the Obama Administration, but the decision was reversed by the Trump Administration in 2017. Because […]

(Beyond Pesticides, November 7, 2023) Two decades after the introduction of genetically engineered, herbicide-resistant crops and the consequential exponential growth in weed killers, Brazil is seeing an increase in childhood cancer. This is the conclusion reached in a comprehensive study spanning 15 years (2004-2019), “Agriculture Intensification and Childhood Cancer in Brazil,” published in Proceedings of the National Academy of Sciences (PNAS) in October. For the past 20 years, soybean herbicides have been killing and sickening children in the Cerrado and Amazon regions–where soybean cultivation is concentrated. The study reveals a link between an increase in soy cultivation and a spike in cases of acute lymphoblastic leukemia (ALL), the most common cancer affecting children, among indirectly exposed populations. Researchers identify pesticide-contaminated drinking water as the driving force behind the increased cancer rates occurring downstream from soybean sites.  In 2003, Brazil legalized its first official genetically modified (GM) crop, welcoming the era of GM soybeans and sparking a radical transformation in its agricultural landscape–for better or worse. The introduction of Monsanto’s Roundup Ready soybean seed promised farmers an efficient and herbicide-resistant alternative to traditional crops. A significant shift occurred in the areas dedicated to soy cultivation in the Cerrado region, tripling from […]

(Beyond Pesticides, October 23, 2023) As the immediate threat of a government shutdown has temporarily subsided, concerns are mounting over the potential threats to food safety in the United States if the government shuts down in mid-November. Experts are warning that a shutdown could jeopardize critical food safety inspections and oversight. A partial government shutdown in 2019 disrupted federal oversight of food monitoring for various pathogens and pesticides, as labs were shuttered, with agency employees furloughed. See Beyond Pesticide’s reporting about food safety risks during the last government shutdown. However, it should be noted that residues of pesticides in food continue to raise concerns about safety of food grown in chemical-intensive (conventional) farming operations. The U.S. Department of Agriculture’s (USDA) contingency plans dictate that the Food Safety and Inspection Service (FSIS) continue its regulatory inspection of meat, poultry, and egg products, as mandated by law. However, it is important to note that the FSIS will operate with a reduced workforce, with a portion of employees deemed “essential personnel” for food safety operations. Meanwhile, the Department of Health and Human Services (HHS), which includes the Food and Drug Administration (FDA), is also preparing for a potential shutdown. According to HHS’s contingency […]

(Beyond Pesticides, September 15, 2023) The U.S. Environmental Protection Agency suspended the registration of the herbicide dimethyl tetrachloroterephthalate (DCPA) (also widely known as Dacthal), effective August 22, 2023 and leaves existing stocks (products containing DCPA manufactured before August 22) available on the market. The decision is one of a series of EPA attempts dating to 2013 to get more data from the manufacturer as the agency considers reregistration of DCPA. The suspension is toothless, however, since EPA did not totally close the book on this chemical. Six days before the suspension, EPA signed a settlement agreement with the sole manufacturer, AMVAC Corporation, to reinstate the registration upon receipt of the complete toxicological data—that is, animal and laboratory tests— needed to determine the chemical’s safety and how and where it can be used. DCPA is currently classified by EPA as a possible human carcinogen and has also been shown to be a thyroid hormone disrupter. DCPA is regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Pesticides are supposed to undergo reregistration every 15 years to take new science into consideration, but this process is glacial. Congress amended FIFRA in 1988 to speed up reregistration of products registered before 1984, and […]

(Beyond Pesticides, August 31, 2023) A study published in Environmental Research finds glyphosate levels in the body adversely affect neurological health. Specifically, oral intake (e.g., eating contaminated foods), inhalation, and dermal exposure to glyphosate lowered cognitive function scores, heightened likelihood of severe depressive symptoms, and impaired auditory (hearing) function. Thus, this study provides some of the first evidence linking glyphosate exposure to specific neurological health outcomes among the general U.S. population, indicating the need for further studies on mechanisms driving neurotoxicity and the medical significance over time. Although this study is among the first to highlight specific neurological effects from glyphosate exposure among the general population, this study is not the first to identify potential neurotoxicity from glyphosate exposure. (Previous research cited below.) The ubiquity of glyphosate uses in agriculture—which leaves residues of the toxic chemical in food—and in public areas (e.g., parks, and walkways) may mean that exposures to it represent a significant risk factor for the disease. Glyphosate is already implicated or proven in developing numerous health anomalies, including cancer. The neurological system, including the brain, spinal cord, and a vast network of nerves and neurons, is responsible for many bodily functions—from sensation to movement. However, pesticides play various roles in […]

(Beyond Pesticides, August 14, 2023) Marijuana regulators in the state of Washington issued administrative holds on 18 licenses due to pesticide-contaminated marijuana, forcing producers and processors to cease operations until now. This shutdown of legal marijuana businesses serves as a window into a broader historical backdrop of pesticide issues within the marijuana industry. Within Washington, pesticide concerns have been growing since a study in 2018 of legal marijuana farms in the state had 84.6% (of 26 samples) with significant quantities of pesticides including insecticides, fungicides, miticides, and herbicides. Last year, a national study identified a list of contaminants in 36 states and the District of Columbia and found 551 pesticides within cannabis products. For over a decade, Beyond Pesticides has sounded the alarm about the highly-concentrated levels of pesticides in marijuana products, calling on state officials to require organic marijuana, especially in the context of medical marijuana. The absence of federal regulations for pesticides in cannabis production has raised significant concerns about exposure risks for recreational and medicinal use, exposure risks to workers, and potential environmental contamination impacting wildlife. Since marijuana is classified as a Schedule 1 narcotic under the Controlled Substances Act, the EPA does not regulate pesticides in […]

(Beyond Pesticides, July 12, 2023) A study by University of Delaware entomologist Thabu Mugala and colleagues finds that modifications to their farming methods can reduce slug damage when those changes also encourage natural slug predators, allowing farmers to avoid the endless cycle of pesticide dependency, pest resistance, genetically engineered crops, and synthetic fertilizers. With insects as the target for tens of millions of pounds of agricultural use, growers of the highest-production crops in the U.S., corn and soybeans, continue to find slugs to be a serious problem. Corn and soybean growers who have adopted no-till or conservation tillage and cover crops often think these practices worsen the problem by increasing moisture and decaying plant material in fields, which slugs love. But the cause-and-effect picture is more nuanced and requires strategies that nurture ecological balance. Slugs are the most damaging non-arthropod pest in no-till corn production in the U.S., and truly effective chemical deterrents do not exist at agricultural scale, as Beyond Pesticides noted here, although biological methods may be on the horizon, such as a parasitic nematode already used in Europe that shows promise. The most voracious natural slug hunters are ground beetles, but harvestmen (daddy longlegs), and wolf spiders […]
