(Beyond Pesticides, August 24, 2020) USDA’s Farm Service Agency (FSA) announced on August 10 that it will be reducing reimbursement rates for the organic certification cost share program, which provides reimbursements to organic farms and handling operations. The August 10 Federal Register notice stated that FSA is “revising the reimbursement amount to 50 percent of the certified organic operation’s eligible expenses, up to a maximum of $500 per scope.” The 2018 Farm Bill clearly set reimbursement rates at 75% of the certified organic operation’s eligible expenses, up to a maximum of $750 per regulated activity. This change hurts the transition to organic production at a time when it is crucial that the organic sector grows—eliminating petroleum-based pesticides and synthetic fertilizers that are contributing to devastating pollution, the climate crisis, and biodiversity decline. This action by USDA is unwarranted and completely unacceptable. The 2018 Farm Bill provided new funding for the program and also directed USDA to use the program’s carryover balances from previous years to fund the program for fiscal years 2019 through 2023. Given these sources of funding, there should be plenty of funds available for the program’s operation in fiscal year 2020. Either USDA’s accounting for this program […]

(Beyond Pesticides, August 20, 2020) Persistent organic pollutants (POPs), including banned and current-use pesticides are present in snow and ice on top of Arctic glaciers, according to the study, “Atmospheric Deposition of Organochlorine Pesticides and Industrial Compounds to Seasonal Surface Snow at Four Glacier Sites on Svalbard, 2013–2014,” published in Environmental Science & Technology. Past research finds that air contaminated with these environmentally bioaccumulative, toxic chemicals drift toward the poles, becoming entrapped in ice under the accumulating snowfall. As the global climate continues to rise and the climate crisis worsens, studies like this become significant, as glaciers encapsulating these toxic chemicals are melting. Upon melting, some chemicals can volatize back into the atmosphere releasing toxicants into air and aquatic systems, with the ensuing consequences. Although this research demonstrates that specific computer programs can track the trajectory of chemically contaminated air parcels with practical precision, it falls to global leaders to curtail the continued manufacturing of these chemical pollutants. [For related pieces, see Silent Snow: The unimaginable impact of toxic chemical use and DDT in Glacial Melt Puts Alaskan Communities at Risk.] Countless scientists consider Arctic environments to be “pristine,” void of direct chemical inputs from pesticides and other POPs. However, the Arctic has become a sink for […]

(Beyond Pesticides, August 17, 2020) Once numbering in the millions, barely 29,000 western monarch butterflies were found in California at last count. Pesticides pack a one-two punch against monarchs. Insecticides—particularly neonicotinoids—poison the caterpillars and butterflies as they feed. Glyphosate—the active ingredient in Bayer-Monsanto’s Roundup® — is wiping out milkweed, the only food source for monarch caterpillars. This has contributed to monarchs’ 90% decline in the past 20 years alone. They could vanish within our lifetimes. Home and garden stores like Lowe’s and Home Depot can play a huge role in ending the use of this toxic pesticide in our backyards and across the country. Already, Lowe’s is removing neonicotinoid products from its live plant offerings and store shelves, and Home Depot is eliminating use of neonicotinoids in its live plant offerings. They could stop selling Roundup®. More importantly, they could encourage organic practices through their product offerings and consumer education. Ask Home Depot and Lowe’s to get Roundup® off their shelves and promote and educate on organic! Companies like Lowe’s and Home Depot could be leaders by removing products containing glyphosate/Roundup® from their physical stores and online—following the example of their competitor, Costco. This would send a powerful message to Bayer […]

(Beyond Pesticides, August 13, 2020) Levels of the notorious herbicide compound glyphosate in the human body are reduced by 70% through a one-week switch to an organic diet, finds a new, peer-reviewed study published in August 2020 in the journal Environmental Research. This result emphasizes both the ubiquity of this compound in the human body, and diet as the primary source of exposure for most people. It also adds to the evidence for Beyond Pesticides’ assertions that: (1) chemical-intensive agriculture must be abandoned, for a variety of reasons that include human health, and (2) in the lead-up to a transition to organic and regenerative agriculture, consuming organic foods as much as is practicable is powerful protection from glyphosate, and from the assault of multiple chemical pesticides to which most people are exposed. Glyphosate is the active ingredient in the popular weed killer RoundupTM, which has been used intensively in the U.S. and around the world, especially during the last couple of decades. It is very commonly used on crops grown from genetically engineered (GE) companion seeds for a variety of staple crops (e.g., soybeans, cotton, and corn). These GE seeds are glyphosate-tolerant, whose attribute has allowed growers to apply the herbicide and […]

(Beyond Pesticides, August 6, 2020) New research finds that a decline in wild pollinator abundance, notably wild bees, limits crop yields in the U.S., according to the study, “Crop Production in the USA Is Frequently Limited by A Lack of Pollinators.” The study results, published in the journal Proceedings of the Royal Society B, find the annual, national average value of wild bee pollination for the most economically important and pollinator-dependent crops is approximately $1.5 billion, with the total value of all U.S. pollinator-dependent crops equaling $50 billion annually. The United Nations states that 75% of the 115 top global food crops depend on insect pollination, with one third of all U.S. crops dependent on pollinators, according to the U.S. Department of Agriculture (USDA). However, research finds that many insect populations are declining by half with a third threatened by extinction, including managed and wild pollinators, mainly due to habitat fragmentation, climate change, and extensive pesticide use. With the global reliance on pollinator-dependent crops increasing over the past decades, a lack of pollinators threatens food security and stability. The researchers in the study note, “Our findings show that pollinator declines could translate directly into decreased yields or production for most of the crops studied, […]

(Beyond Pesticides, July 30, 2020) Simultaneous exposure to pesticides and noise from agricultural machinery increases farmworkers, risk of hearing loss, according to the study, “Hearing Loss in Agricultural Workers Exposed to Pesticides and Noise,” published in the journal Annals of Work Exposures and Health. Hearing loss is the 3rd most common health issue in the U.S., affecting eight million Americans. Although specific conditions like age, illness, and genetics, can mediate hearing loss, research suggests other factors can induce auricle (ear) damage, including medications, exposure to toxic chemicals (including pesticides), and loud, ongoing noise. Past studies find an association between hearing loss and pesticide exposure or noise exposure, alone. However, this study is one of the first to associate hearing loss with the additive effect to concurrent, persistent pesticide exposure, and noise. This research is significant as human senses are integral to everyday human activities, and it is vital to understand how chronic pesticide exposure can limit the body’s ability to function normally, for farmers and everyone alike. Researchers in the study note, “[I]t is necessary to understand what work-related factors are contributing to this high prevalence of hearing loss in [Thai] agricultural workers in order to develop effective interventions and […]

(Beyond Pesticides, July 16, 2020) Long-term exposure to sublethal (low-level) concentrations of the neonicotinoid in soil negatively affects the health and behavioral development of black garden ants (Lasius niger) colonies, according to a study published in Communications Biology by scientists at the University of Bern, Switzerland. Ants are one of the most biologically significant insects in the soil ecosystem, acting as ecosystem engineers. Their burrowing behavior aerates the soil, allowing oxygen and water to penetrate down to plant roots. Additionally, ants increase soil nutrient levels by importing and accumulating organic material like food and feces, thus enhancing nutrient cycling. Like many other insects, ants are unfortunate victims of the global insect apocalypse or population decline, and much research attributes the recent decline to several, including pesticide exposure. Broad-spectrum pesticides, like neonicotinoids, indiscriminately kill pests and nontarget organisms alike, as their ubiquitous use contaminates soils, even in untreated areas. This study highlights the necessity of rethinking chemical pest management, developing sustainable agricultural practices that reduce the use of agrochemicals, like pesticides, to prevent permanent environmental ecosystem damage. Researchers in the study note, “To prevent irreparable damages to functioning ecosystems, [we] suggest to either fully incorporate long-term effects in risk assessment schemes, or to make a shift […]

(Beyond Pesticides, July 13, 2020) Soil is central to organic production. Therefore, hydroponic operations should not be considered eligible for organic certification, and the National Organic Program (NOP) must take a clear position in opposition to hydroponics and other non-soil-based methods in organic production, including containers. Organic farmers and consumers strongly agree that organic production must be soil-based.  Tell NOP hydroponics is not organic! Educate your congressional representatives and senators. NOP authorizes the certification of hydroponic operations as organic. This undermines the authenticity of organic farming and creates unequal competition, market instability, and consumer distrust in organic certification. Organic farming and soil are inextricably linked. The microorganisms in healthy soils interact in a symbiotic manner with plant roots, strengthening the plant, enabling it to resist diseases and facilitating water and mineral uptake. The essence of organic production is maintaining and enhancing the organic matter content of soil by relying on environmentally beneficial methods such as green manure, crop rotation, and biological pest management. On March 3, 2020, the Center for Food Safety (CFS) filed a lawsuit challenging the USDA’s decision to allow hydroponics operations to be certified organic. Organic farmers and consumers believe that the organic label means two things: […]

(Beyond Pesticides, July 9, 2020) Conventional U.S. milk contains growth hormones, antibiotics, and low to elevated levels of pesticides not found in organic milk, according to a study published in the journal of Public Health Nutrition by Emory University researchers. Milk can bioaccumulate certain organic pollutants, making it a valuable medium to assess what chemical we might be ingesting daily. With milk being one of the most consumed beverages in the U.S., in addition to its use in other popular drinks (i.e., coffee and tea), this study discloses widespread contamination and highlights the need for improved regulation. Researchers in the study note, “To our knowledge, the present study is the first study to compare levels of pesticide in the U.S. milk supply by production method (conventional vs. organic). It is also the first in a decade to measure antibiotic and hormone levels and compare them by milk production type.”  The market for conventional milk, produced in chemical-intensive agriculture, is declining, but the demand for organic milk is increasing due to concerns over chemical contamination in consumer products from pesticides and other toxic chemicals. Although the U.S. Environmental Protection Agency (EPA) sets limits for pesticide residues in food products, the agency […]

(Beyond Pesticides, June 30, 2020) A review of scientific literature on the toxic effect of environmental contaminants—including pesticides—published in the journal Toxicological Science, “The Impact of Environmental Chemicals on the Gut Microbiome,” associates these chemicals to changes in the gut microbiome and other adverse health implications. The review, by researchers at the University of Illinois, looks at how environmental contaminants adversely effects and reinforce chemical disruption of the gut microbiome. It highlights the importance of evaluating how environmental contaminants, like pesticides, impact body regulation by gut microbiota. The study has significant implications for considerations that should be, but are not currently, a part of pesticide review and registration by the U.S. Environmental Protection Agency (EPA). Gut microbiota plays a crucial role in lifelong digestion, immune, and central nervous system regulation, as wells as other bodily functions. Through the gut biome, pesticide exposure can enhance or exacerbate, the adverse effects of additional environmental toxicants on the body. Since the gut microbiome shapes metabolism, it can mediate some toxic effects of environmental chemicals. However, with prolonged exposure to various environmental contaminants, critical chemical-induced changes may occur in the gut microbes, influencing adverse health outcomes. Karen Chiu, Ph.D., a graduate research fellow at the […]

(Beyond Pesticides, June 18, 2020) Residential exposure to household pesticide products increases the risk of developing symptoms associated with depression, according to a study published in Environmental Research by researchers at Medical College of Georgia—Augusta University, School of Medicine—Jinan University, and Guangzhou Center for Disease Control and Prevention (CDC), China. Research on pesticide-induced diseases commonly investigates pesticide exposure concerning the development of various physical illnesses, and previous studies show there are occupational risks of developing depression, especially in agriculture where pesticide use is rampant. However, there is a lack of information connecting pesticide exposure to the subsequent psychological (psychiatric) effects on the general population. Additionally, household pesticide exposure varies from occupational exposure via exposure frequency, duration, intensity, and type. This research highlights the significance of researching potential mental health effects resulting from pesticide exposure, especially as society tends to rank mental health risks second to physical health. The study’s scientists note, “Our results highlight the importance of the cautious use of household pesticides because the chronic effects of poisoning may contribute to an elevated risk of depression.”  According to the World Health Organization (WHO), depression affects 322 million people globally, with the number of diagnosed patients increasing by 18.4% from 2005 to 2015. Although the etiology of depression—and […]

(Beyond Pesticides, June 2, 2020) During the April meeting of the National Organic Standards Board (NOSB), there was near-unanimous sentiment expressed by NOSB members and stakeholders that the failure of the National Organic Program at USDA to act on NOSB recommendations regarding so-called “inert” ingredients hurts organic producers and consumers and the environment. The NOSB has only one alternative left to force USDA action—denying relisting at the Fall meeting. Tell the National Organic Program and USDA Secretary Sonny Perdue to initiate action to begin NOSB review of “inerts” now. Dr. Asa Bradman, who summarized the issue for the NOSB at the Spring 2020 meeting, is an expert in environmental health, and as part of his day job, leads studies focusing on pesticides, flame retardants, metals, emerging pollutants, VOCs, indoor air quality and other contaminants. As he said at the meeting, “These are often active ingredients.” In fact, the ingredients not listed on a label of a pesticide product—which are not fully reviewed for their adverse effects—may be the most toxic chemicals in the formulation. Recent research, Toxicity of formulants and heavy metals in glyphosate-based herbicides and other pesticides (Toxicology Reports 5, 2018), by Defarge, de Vendômois, and Séralini demonstrates the need to […]

(Beyond Pesticides, May 26, 2020) Across the pond, the European Commission (EC) has announced plans to protect biodiversity and build a more sustainable food system, and identified the reduction of pesticide use  and the expansion of organic agriculture as pillars of the scheme. The EC expects that the initiative, which will require EU member states’ endorsement, will advance progress on the EU goal of eliminating greenhouse gas emissions by 2050, given that 10% of emissions arise from the agricultural sector. The EC’s goals are important and laudable, but Beyond Pesticides is clear: reduction of pesticide use in service of them is not an adequate strategy to ensure long-term success. Genuine success requires the elimination of the use of synthetic chemical pesticides, fertilizers, and other toxic inputs, and the transition to agricultural and land management systems that work with nature, rather than fight against it. Regenerative, organic practices are the path to a livable future, according to Beyond Pesticides. The EC, which is the executive branch of the EU, expects its plan to reduce use of pesticides by 50% by 2030; reduce use of antimicrobial chemicals, including antibiotics, in fish and animal farming by 50%; dedicate a minimum of 25% of arable […]

(Beyond Pesticides, May 22, 2020) For years, USDA has been looking the other way as giant corporate agribusinesses, primarily producing conventional eggs and poultry, have squeezed family-scale farmers out of the market and misled and defrauded consumers. Due to a lawsuit challenging the Trump administration on the scuttling of new rules that would make it harder for factory farms to qualify for organic status, USDA is seeking input on what was previously an error-filled and biased economic assessment of the rulemaking. Please sign the letter by noon on Tuesday, May 26, to include your voice in our response to the official proceedings. If you would prefer to write your own custom comment you can submit it on Regulations.gov. Letter to National Organic Program (Jenny Tucker, Ph.D. To the National Organic Program: Please include my comment below in evaluating the economic analysis report pursuant to the Organic Livestock and Poultry Practices rulemaking. Docket number: AMS-NOP-20-0037 Both the current and previous OLPP analyses include the following misstatements and omissions: It is a misconception to refer to, and judge, the economic impacts of the OLPP as if the requirement for outdoor access was a new and onerous regulation.

(Beyond Pesticides, May 21, 2020) Use of the herbicide dicamba increases humans’ risk of various acute and chronic cancers, according to research published in the International Journal of Epidemiology by the National Institutes of Health (NIH). Many pesticides are “known or probable” carcinogens (cancer-causing agents), and their widespread use only amplifies chemical hazards, adversely affecting human health. However, past research lacks comprehensive information regarding human health effects associated with long-term pesticide use. This study highlights the significant role that long-term research plays in identifying potential health concerns surrounding registered pesticides, especially as the Environmental Protection Agency (EPA) plans to reaffirm its decision to allow dicamba use on genetically engineered (GE) crops. Nathan Donley, Ph.D., a scientist with the environmental health program at the Center for Biological Diversity, comments: “This sweeping study exposes the terrible human cost of the EPA’s reckless decision to expand the use of dicamba. […]For the EPA to approve widespread use of this poison across much of the country without assuring its safety to people and the environment is an absolute indictment of the agency’s persistent practice of rubber-stamping dangerous pesticides.” Dicamba—a benzoic acid chemical that controls broadleaf weeds—is one of the most widely applied herbicides in corn production. As a result of weed resistant to […]

(Beyond Pesticides, May 19, 2020) The California Department of Food and Agriculture (CDFA) is taking public comments on a proposal to establish statewide comparable-to-organic standards for cannabis production. Although cannabis remains illegal at the federal level, and thus cannot be labeled with the U.S. Department of Agriculture (USDA) certified organic seal, there is no prohibition on a state-specific program that follows federal organic requirements, but does not use the word “organic.” While such a program has the potential to provide another level of protection for medical patients, questions and concerns remain over the allowance of certain products, and the impact the certifying scheme may have on the future trajectory of the cannabis production industry. Under the Medicinal and Adult-Use Cannabis Regulation Safety Act, passed in 2017 after the success of Proposition 64 by California voters, state agencies were tasked with establishing a state-level program to certify cannabis to the standards set out by USDA’s National Organic Program (NOP). CDFA is required to finalize this program for cannabis production by the start of 2021, while the California Department of Public Health will create a separate program to certify manufactured cannabis products. As outlined by CFDA, cannabis would be certified through third-party […]

(Beyond Pesticides, May 11, 2020) Protecting ourselves from Covid-19 requires not only that we avoid contact with the virus, but also that we avoid exposing ourselves to chemicals that may disrupt our immune or respiratory systems. But when it comes to pesticide products—and disinfectants are pesticides—we encounter once again the problem of so-called “inert,” or nondisclosed, ingredients. Tell EPA and Congress that ALL Ingredients in Pesticides Must Be Disclosed. “Inert” ingredients are not necessarily chemically or biologically harmless. “Inert” or “other” ingredients—as distinguished from “active” ingredients—are generally the majority of the product formulation that makes up the liquid, spray, dust, or granule, but does not specifically attack the pest, according to the manufacturer. They include emulsifiers, solvents, carriers, aerosol propellants, fragrances, and dyes. Many “inerts” are quite toxic, and may be “active” ingredients in other products. “Inert” ingredients may also be described as “adjuvants” or “formulants.” “Inerts” are typically not listed on the label, and hence are often called “secret ingredients.” Beyond Pesticides reviews the disinfectants on EPA’s List N, which are approved for use against the novel coronavirus, but it is only possible to review the active ingredients. One product on the list, for example, contains 99.7784% “other ingredients.” Unfortunately, although this product may […]

(Beyond Pesticides, May 1, 2020) As the globe settles in for a long summer of social distancing to prevent the spread of COVID-19, experts warn that concentrated animal feeding operations (CAFOs), more commonly referred to as “factory farms,” are setting the table for the next pandemic. Crowded conditions and prophylactic use of antibiotics, scientists say, are creating an environment ripe for viruses and bacteria to evolve and jump from animal to human populations. The Food and Agriculture Organization of the United Nations said back in 2013, “Livestock health is the weakest link in our global health chain.” Alternatively, organic principles offer an existing federal guideline for ecologically and environmentally viable conditions for agriculture. Michael Greger, M.D., Ph.D., author of Bird Flu: A Virus of Our Own Hatching, explains, “When we overcrowd animals by the thousands, in cramped football-field-size sheds, to lie beak to beak or snout to snout, and there’s stress crippling their immune systems, and there’s ammonia from the decomposing waste burning their lungs, and there’s a lack of fresh air and sunlight — put all these factors together and you have a perfect-storm environment for the emergence and spread of disease.” Dr. Greger notes that the spread of […]

(Beyond Pesticides, April 30, 2020) Chemical-intensive farming of crops for animal fodder powers the global market for highly hazardous pesticides (HHPs), according to data analyzed by Unearthed, and the Swiss NGO Public Eye. Animal fodder production not only intensifies global pollution, but it also increases pesticide exposure and degrades human, animal, and environmental health. This data analysis supports advocates advancing pesticide policies to eliminate HHPs by identifying which toxic chemicals lead global pesticide sales. However, it will take more than eliminating the worst chemicals to address the impending biodiversity collapse and the climate crisis, according to experts who point to the need for an urgent shift to organic land and agricultural management practices. United Nations’ (UN) special rapporteur on toxic substances and human rights, Baskut Tuncak, says, “There is nothing sustainable about the widespread use of highly hazardous pesticides for agriculture. Whether they poison workers, extinguish biodiversity, persist in the environment, or accumulate in a mother’s breast milk, these are unsustainable, cannot be used safely, and should have been phased out of use long ago.”  Unearthed and Public Eye investigated over $23 billion in global pesticide market sales to determine the proportion of pesticides considered highly hazardous by the Pesticide Action Network’s […]

(Beyond Pesticides, April 23, 2020) Pesticide spray drift from adjacent farmlands expose butterfly larvae to lethal pesticide concentrations, according to research published in Environmental Toxicology and Chemistry by Iowa State University (ISU). Lack of previous experimental pesticide toxicity data makes it unclear as to what degree insecticides impact monarch butterfly (Danaus plexippus) productivity in milkweed (Asclepias spp.) habitats near pesticide-treated pasture. This study adds weight to the idea that pesticides are playing a role in the ongoing decline of this iconic butterfly, as researchers find insecticide drift from adjacent fields to be strongly associated with larval mortality. Future monarch butterfly conservation efforts should consider risks stemming from pesticide exposure when developing butterfly rehabilitation efforts, according to advocates. As co-author Niranjana Krishnan (ISU graduate student) states, “In order to make the best decisions about how and where to plant milkweed, we first need to find basic toxicity and exposure data.”  ISU researchers established monarch butterfly colonies by collecting larvae from roadside milkweeds, which they then reared in the laboratory for incubation. To analyze the relative toxicity of various insecticides on monarch butterflies, researchers applied normal field-application rates of each pesticide at different larval development stages. Scientists used a bioassay to measure the […]

In 1962, Rachel Carson said we stood at a crossroads: “The road we have long been traveling is deceptively easy, a smooth superhighway on which we progress with great speed, but at its end lies disaster. The other fork of the road — the one less traveled by — offers our last, our only chance to reach a destination that assures the preservation of the earth.” Eight years later, on April 22, 1970, the first Earth Day encouraged collective action for conservation. Now, in the midst of a pandemic and cascading environmental crises (arguably, down the road of disaster), forging a new path toward restoration will take courage and imagination. This Earth Day, Beyond Pesticides is putting forth a toolkit to abandon half measures and forge ahead with an organic approach for repairing human health and the environment. LISTEN TO SCIENCE Biodiversity is plummeting worldwide. The climate crisis looms even as COVID-19 grabs headlines. Environmental pollution is a predictor of coronavirus death. Never has it been more obvious that the global community is interconnected, and enforcing preventative measures is critical before it is too late. Meanwhile, the Trump Administration’s Environmental Protection Agency (EPA) ignores science, moving ahead with deregulation to […]

(Beyond Pesticides, April 20, 2020) As USDA takes public comments on its updated dietary guidelines, it important that sustainable, regenerative organic food production practices are an integral part. Since 1990, Congress has required an every-five-years review of its Dietary Guidelines — recommendations intended to promote public health and prevent chronic diseases. The next review and a draft updated version, the 2020–2025 Dietary Guidelines for Americans, is currently underway. USDA says that the dietary guidelines provide “information that helps Americans make healthy choices for themselves and their families.” In order to make healthy food choices, the guidelines must go beyond the traditional parameters to include how the food is produced. How food is produced affects the health of Americans not only as a result of the nutritional quality of the food, but also due to environmental contamination. Sign the petition to USDA and send a letter to Congress. Tell them that organic food must be emphasized in new dietary guidelines. Although research on the nutritional density of organic produce is equivocal, showing some higher levels of antioxidants, results are decidedly clear for animal products. Pastured organic animal products—including beef, lamb, pork, dairy, poultry, and eggs—have been shown to be superior to that of products of […]

(Beyond Pesticides, April 16, 2020) Pesticide exposure in farmland birds is a concomitant of pesticide-treated muesli (cereal) seed commonly planted during winter months, according to research published in Science of the Total Environment by United Kingdom (UK) scientists. Not only do pesticide-treated seeds pose the highest dietary risk to birds, but pesticide-treated seeds also go underreported as farmers often lack knowledge of what pesticides are on the seeds they plant. This study emphasizes the global effects of treated seeds, and their corresponding pesticide exposure, on bird species. Future risk assessments for bird should address these implications when implementing agricultural pesticide policies.  Farmers use of treated seeds exposes farmland birds to pesticides like neonicotinoids (neonics), including clothianidin (CLO). Pesticide residues then accumulate in the birds’ blood. UK scientists examined pesticides in farmland bird blood samples to connect the field-based use of treated seeds to clothianidin exposure patterns. At the time of this study, CLO was the most widely used pesticide on treated winter cereal seeds in the UK. Scientists recorded the presence of neonicotinoid-treated seed in 39 fields of 25 farms after seeding. Camera traps monitored farmland birds’ seed consumption. To measure CLO concentration in treated seed and seedling, scientists used liquid chromatography-tandem mass spectrometry to identify inorganic, organic, […]
