(Beyond Pesticides, July 30, 2019) Earlier this month, the U.S. Environmental Protection Agency announced a decision to register new uses for the bee-toxic pesticide sulfoxaflor. The decision closely followed a USDA announcement halting the Honey Bee Colonies Survey, combining blows to already suffering beekeepers. According to the nonprofit Bee Informed, this past winter tallied the most colonies lost in a decade—an estimated 37% between October 1, 2018 and April 1, 2019. “Proposing to register sulfoxaflor for use on bee-attractive crops, in the midst of an ongoing pollinator crisis, is the height of irresponsibility,” said Drew Toher, community resource and policy director for Beyond Pesticides in an interview for Bloomberg Environment. “When all of the available data points to significant risks to pollinators from use of this chemical we must face the facts: EPA is working towards the protection of pesticide industry, not the environment,” he said. Sulfoxaflor is a systemic insecticide whose mode of action is the same as neonicotinoid pesticides. After application, the chemical is absorbed and distributed throughout the plant, including pollen and nectar. These insecticides are selective agonists of insects’ nicotinic acetylcholine receptors—they bind to the receptor and cause it to activate. The impact on foraging bees […]

(Beyond Pesticides, July 17, 2019) A March 2017 bird kill incident in Modesto, CA can be traced directly back to an insecticide “soil drench” applied to the base of several elm trees by pesticide applicators hired by the city, as detailed in a study published last month in the Journal of Environmental Toxicology and Chemistry. The chemical in question, the neonicotinoid imidacloprid, is implicated in the ongoing pollinator crisis and insect apocalypse, but can also affect bird populations. Prior research estimated that a single seed coated with the insecticide is enough to kill a songbird; this study confirms that such a scenario can and does play out in the real world. Progress and improvement will only occur when pest management practices stop focusing on pesticide use to solve routine pest problems and emphasize prevention. As part of city-wide pest management activities, Modesto officials said that imidacloprid was applied to elm trees in several front yards in a local neighborhood. The application took the form of a “soil drench,” which is when pesticide products are applied to the soil around the base of a tree or shrub. The systemic property of imidacloprid and other systemic insecticides means that the chemical will […]

(Beyond Pesticides, June 24, 2019) A study finds that the interaction of a common honey bee parasite with neonicotinoid insecticides causes 70% reductions in overwintering honey bee survival. These results help to explain the unsustainable honey bee colony losses observed in recent decades. Neonicotinoids (neonics) are a class of insecticides that share a common mode of action that affect the central nervous system of insects. Studies show that neonicotinic residues accumulate in pollen and nectar of treated plants, and, given their widespread use and known toxic effects, there is major concern that neonics play a major contributing role in pollinator declines. In the early 2000s, Colony Collapse Disorder (CCD) brought national attention to increased honey bee colony losses. During the same period that CCD and colony losses spiked, neonic prevalence skyrocketed, in large part due to the introduction of seed-delivered technologies. As of 2011, 34-44% of soybeans and 79-100% of maize hectares were preemptively treated with neonics. While CCD prevalence has decreased, colony loss rates (and systemic insecticide use) remain high. A 2018 national survey indicates that U.S. beekeepers currently experience an average annual colony mortality rate of 30.7%, double the pre-CCD baseline of 15% losses. In the present study, […]

(Beyond Pesticides, June 24, 2019) During “Pollinator Week,” last week, the U.S. Environmental Protection Agency betrayed its responsibility to protect the environment and approved “emergency” uses of sulfoxaflor, a bee-toxic insecticide, in 11 states on millions of acres of crops that are attractive to bees. Sulfoxaflor is functionally identical to the neonicotinoid class of systemic pesticides, which are readily absorbed and translocated into the plant tissues, including its pollen and nectar. These insecticides are substantial contributors to the dramatic decline of pollinators and what is now recognized as a global insect apocalypse. Ask Your Elected Members of Congress to Tell EPA that Its Actions Are Unacceptable and Must Be Reversed In 2015, beekeepers sued to suspend the use of sulfoxaflor. A year later, in 2016, the chemical’s registration was amended with the specific exclusion of crops such as cotton and sorghum that attract bees, essentially acting as an aromatic draw to poison. However, EPA regularly utilizes the “emergency exemption” rule under Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to circumvent these restrictions. The Center for Biological Diversity reports, “Ten of the 11 states have been granted the approvals for at least four consecutive years for the same ’emergency.’ Five have […]

(Beyond Pesticides, June 19, 2019) To mark National Pollinator Week (June 17-23), more than 10,000 people across the country are joining to demand that Kroger (NYSE: KR) help stop the extreme decline of pollinators. Customers are delivering letters to stores asking the nation’s largest conventional grocery store to eliminate pollinator-toxic pesticides from its food supply chain and increase domestic organic food offerings to help stop the catastrophic decline of pollinators and other insects. Pollinators and other insects could go extinct within a century, threatening a “catastrophic collapse of nature’s ecosystems,” the first comprehensive global meta-analysis of insect decline states. This is largely due to the widespread use of neonicotinoids and other toxic insecticides in industrial agriculture. “Systemic neonicotinoid insecticides and the broad range of pesticides that harm people and pollinators have no place in our food supply,” said Drew Toher, community resource and policy director at Beyond Pesticides. “Kroger customers are asking the company to be part of the solution to the pollinator crisis by eliminating hazardous pesticides and expanding organic options.” “To avoid the ‘bee apocalypse’ it is critical that Kroger immediately commit to stop selling food with pollinator-toxic pesticides,” said Tiffany Finck-Haynes, pesticides and pollinators program manager at […]

(Beyond Pesticides, June 19, 2019) On June 17, 2019, the Environmental Protection Agency (EPA) once again approved “emergency” uses of sulfoxaflor, a bee-toxic insecticide, on millions of acres of crops that are attractive to bees. Sulfoxaflor is functionally identical to the neonicotinoid class of systemic pesticides, which are readily absorbed and translocated by the plant, including its pollen and nectar.

A 2018 report from OIG notes […]

(Beyond Pesticides, June 14, 2019) Next week, June 17–22, marks Pollinator Week 2019, a celebration of the beauty and benefits these critical species provide, but also a call to action to protect pollinators and the natural world. Since United States Senate declared the first Pollinator Week in 2007, nearly every week since there has been new research published linking pesticides to pollinator declines. Yet the companies that produce pollinator-toxic pesticides, like Bayer and Syngenta, make use of this week to excuse their products from any culpability. Instead, they sponsor events and posters, discussing every threat to bees except those posed by the pesticides that make up their bottom line. They are the villains in this story, but there is no superhero in line to save bees, butterflies, birds, and bats.  That’s why it’s up to you, everyday heroes that support protecting pollinators, to alert the public, and inspire good in elected officials. We’ve outlined a week of actions aimed at educating and inspiring action to protect pollinators. Monday Support the New Saving America’s Pollinators Act (SAPA), HR1337. SAPA represents the best opportunity to enact meaningful changes at the federal level that will protect pollinators in the long term. This bill, […]

(Beyond Pesticides, June 12, 2019) A new study finds that the widespread insecticide fipronil causes transgenerational toxicity across generations of zebrafish. Fipronil, already known to be highly toxic to aquatic organisms, is now implicated in causing even more damage than previously thought. Even individuals who are not themselves directly exposed are shown to suffer from maternally transmitted toxic effects, including a more than doubled mortality rate. The study, published in Environmental Pollution, tracks hatching, growth, and survival of offspring whose mothers were exposed to fipronil. Researchers exposed a total of 90 adult female zebrafish to environmentally relevant levels of fipronil, within the range of concentrations known to occur in U.S. surface waters, for a period of 28 days. After exposure, females were mated with unexposed males, and their offspring were monitored for hatching, growth, locomotor behavior, heart rate, toxicity and gene expression assays. The conclusion: maternal fipronil exposure induced multiple toxic effects in offspring, including a 30% reduction in hatch rates and, alarmingly, a more than doubling of the offspring mortality rate. Fipronil is a broad-spectrum insecticide widely used for indoor and turf pest control in the U.S., and identified as a ubiquitous contaminant of U.S. surface waters. Fipronil is […]

(Beyond Pesticides, June 10, 2019) On May 20, U.S. Representative Nydia Velazquez, with 18 co-sponsors, introduced H.R. 2854, “To amend the National Wildlife Refuge System Administration Act of 1966 to prohibit the use of neonicotinoids in a National Wildlife Refuge, and for other purposes.” The bill follows an August 2018 Trump administration announcement that reversed a 2014 U.S. Fish and Wildlife Service (FWS) decision to ban neonicotinoid insecticides on National Wildlife Refuges. Tell members of Congress to protect biodiversity by co-sponsoring HR 2854, which reinstates the 2014 U.S. Fish and Wildlife Service ban on neonicotinoid pesticide use in wildlife refuges that was reversed by the Trump administration in 2018. The administration’s action threatens not only pollinators, but contributes to the attack on biodiversity worldwide. “These pollutants upset the delicate ecosystems of our Wildlife Refuges and they have no place in our public lands,” said Rep.Velázquez. “The ban’s revocation comes as mounting evidence suggests the chemical has damaging environmental effects on bees and other pollinators, undermining the national wildlife system,” she continued. In 2014, FWS announced that all National Wildlife Refuges would join in the phase-out of neonics (while also phasing out genetically engineered crops) by January 2016. FWS “determined that prophylactic use, such as […]

(Beyond Pesticides, May 30, 2019) Last week, the U.S. Fish and Wildlife Service (FWS) agreed to a 2020 deadline for reaching a decision on protection status for monarch butterflies under the Endangered Species Act. This agreement comes nearly five years after the filing of a petition by conservationists with the Center for Biological Diversity and Center for Food Safety led to the launch of an ongoing status review in 2014. While FWS deliberates, monarch butterflies continue their staggering, decades-long population decline, perhaps for the last of their decades. In the 1990s, the eastern monarch population numbered nearly one billion butterflies, and the western population numbered more than 1.2 million. Last year’s winter counts recorded around 93 million eastern monarchs and fewer than 200,000 western monarchs. That loss is “so staggering that in human-population terms it would be like losing every living person in the United States except those in Florida and Ohio,” Tierra Curry, a senior scientist at the Center for Biological Diversity, said in a statement to Live Science. Recent studies project that if current trends continue, both eastern and western monarch populations face migratory collapse within the next 20 years. FWS is no stranger to the threats facing monarch […]

(Beyond Pesticides, May 23, 2019) On Monday in the conclusion of a lawsuit, the U.S. Environmental Protection Agency (EPA) announced the final notices of cancellation on the registration of twelve neonicotinoid pesticide products in the Federal Register, each of which contains chlothianidin or thiamathoxam as an active ingredient. The decision to pull these products from the market was required as part of a legal settlement under the Endangered Species Act (ESA) in December 2018 of a successful case, Ellis v. EPA, brought by beekeeper Steve Ellis and a coalition of other beekeepers and environmental groups, including Beyond Pesticides. The case establishes a legal precedent in which the court required action to address the bee-toxic effects of pesticides; however, the effect of the settlement and its impact on overall neonicotinoid and other systemic insecticide use is limited. For all but two of the twelve canceled products, a nearly identical surrogate remains actively registered. Furthermore, the fact remains that there are hundreds more products containing the active ingredients targeted by the lawsuit that have not been removed in any capacity – 106 products containing clothianidin and 95 containing thiamethoxam remain untouched on the market. Breaking down the impacts of the EPA ruling even […]

(Beyond Pesticides, April, 30, 2019) According to the latest blog post from pesticide industry propagandist Henry I Miller, the pollinator crisis either a) is not occurring; b) is not a problem; or, c) caused by varroa mites, pathogens, and habitat loss. Notwithstanding outlandish assertions that there is no pollinator crisis, new research is further undermining the long-held industry claim that it is mites and disease alone, and not pesticides that are harming pollinator populations. Published in the journal Scientific Reports by a team of Canadian scientists, this research finds that realistic exposure to neonicotinoid insecticides impairs honey bees ability to groom mites off of their bodies and increases infection with a disease known as deformed wing virus (DWV). “When bee colonies began to collapse years ago, it became clear there wasn’t just one factor involved, so we were interested in whether there was an interaction between two of the main stressors that affect bees: varroa mites and a neurotoxic insecticide, clothianidin,” said Nuria Morfin Ramirez, PhD, at the University of Guelph, Canada. Dr. Ramirez and her team exposed honey bees to a range of different concentrations (low, medium, high) of the neonicotinoid clothianidin, with some bees receiving combined stressors of […]

(Beyond Pesticides, April 25, 2019) As reported by Mother Jones, the New York Times (NYT) published, on April 6, a distressing report about a deadly fungus that has been advancing steadily across the world during the past five years. Candida auris is an emerging fungal pathogen that threatens those with compromised or immature immune systems, such as infants, the elderly, people taking steroids for autoimmune disorders, diabetics, those undergoing chemotherapy, and even smokers. Nearly half of those who contract a C. auris infection die within 90 days. One of the factors making this fungus so deadly is that it has developed resistance to existing antifungal medicines, with 90% of infections resistant to one drug, and 30% to two or more. As is true for resistant bacteria, culprits in C. auris’s development of resistance may be the overuse of antifungal medications in health care and overreliance on fungicides in agriculture. The Centers for Disease Control and Prevention (CDC) has added C. auris to its list of pathogens considered “urgent threats.” It is an “emerging fungal pathogen,” meaning that the incidence of infection has been increasing across multiple countries since it was first recognized in 2009 in Japan (although a different strain had […]

(Beyond Pesticides, April 17, 2019)  A neurotoxic pesticide labeled “bee-safe” has been found to be harmful to bees, according to a new study. Flupyradifurone (FPF), the subject of the study, is a novel chemical that was hastily registered in the wake of public awareness about the impact of neonicotinoid insecticides on bees. A systemic insecticide and a nicotinic acetylcholine receptor (nAChR) agonist, it functions in the same way as a neonicotinoid, though it is in the butanolide family. “Lethal and sublethal synergistic effects of a new systemic pesticide, flupyradifurone (Sivanto®), on honeybees,” not only debunks the myth that FPF is safe on its own, it also delves into the FPF’s synergistic effects with a commonly used fungicide propiconazole (PRO). PRO, on its own, has no impact on bee mortality. A rarely studied realm of pesticides, the study defines a synergistic effect as, “when combined exposure to two factors results in an effect that is significantly greater than the sum of individual effects.” Researchers manipulated six healthy honey bee (Apis mellifera ligutica) colonies and observed the impact of varying amounts of pesticide exposure, including both individual and synergistic effects, on behavior and mortality. They recorded data over seasons and between worker […]

(Beyond Pesticides, April 8, 2019) Officials in Europe and the U.S. focus on banning problem pesticides, raising concerns about their replacements in the face of pesticide-intensive management strategies, while organic advocates call for a systems change in land management. In reference to widespread community bans of Roundup/glyphosate, Cary Gillam, author of Whitewash, told last year’s Beyond Pesticides’ Forum, “Glyphosate is the poster child for the bigger pesticide problem.” She continues, “If it goes away tomorrow, we are not okay.” Because of this, Beyond Pesticides has strategically sought to transform our country’s approach to pest management, both agricultural and residential/structural, by eliminating a reliance on pesticides and advancing organic management practices that do not rely on toxic inputs. This Daily News Blog post offers updates on progress in the European Union (EU), in the U.S. Congress, and in communities and sates nationwide. The EU is poised to ban clorothalanil, a commonly used — and highly toxic — organochlorine fungicide, The Guardian reported, in mid-to-late May 2019. After a review by the European Food Safety Authority (EFSA), EU states voted to approve a ban. EFSA identified as a chief safety concern the possibility that breakdown products (metabolites) of the compound may cause damage […]

(Beyond Pesticides, April 5, 2019) Beyond Pesticides’ 37th National Pesticide Forum, Organic Strategies for Community Environmental Health, begins today at the New York Academy of Medicine, and continues until tomorrow night, where the New York City premiere of the new documentary Ground War will take place with special guest Lee Johnson—who successfully sued Monsanto after linking his cancer to exposure to the weed killer glyphosate. (Tickets are $10 and available through Ticketmaster until sold out, please sign up/log in to a Ticketmaster account to purchase). The two-day conference is convened by Beyond Pesticides in collaboration with the Children’s Environmental Health Center of the Icahn School of Medicine at Mount Sinai, and 24 local cosponsoring organizations. The conference begins at 4:30 pm on Friday April 5, followed by a reception and evening session. Saturday includes breakfast and runs from 8:30 am until 5:30 pm. The Ground War screening, to be held at Florence Gould Hall (55 E. 59th Street), starts at 7:30 pm and concludes with a panel discussion featuring advocates and California Groundskeeper Dewayne Lee Johnson. The Forum provides a unique place to network with advocates, scientists, practitioners, policy makers, and other experts on the cutting edge of the pesticide […]

(Beyond Pesticides, April 4, 2019)  Following on its verdict that the herbicide Roundup caused plaintiff Edwin Hardeman’s  non-Hodgkin lymphoma (NHL), the jury on March 27 issued an award of $80 million—$5 million in compensatory damages and $75 million in punitive damages—for improper labeling and negligence on the part of the manufacturer and defendant, Monsanto. The trial, the first federal Roundup cancer trial, marks the first of a multidistrict litigation against Monsanto, with more than 1,600 similar lawsuits pending in San Francisco’s federal court. The jury’s second verdict affirmed Mr. Hardeman’s allegations that Roundup’s design is defective and lacks sufficient warnings, and that Monsanto was negligent by not using reasonable care to warn about Roundup’s NHL risk. The Edwin Hardeman v. Monsanto Co. jury verdict marks the second multi-million dollar award to be granted in a landmark case against Bayer/Monsanto within the past year. Last August in San Francisco Superior Court, California groundskeeper Dewayne “Lee” Johnson was awarded $39 million in compensatory damages, and $250 million in punitive damages in the first case that linked his NHL to Monsanto’s glyphosate/Roundup. In October, the judge in the case upheld the verdict, but reduced the award to $78 million. Mr. Hardeman is represented by […]

(Beyond Pesticides, March 25, 2019) EPA is using a regulatory loophole – the “treated articles exemption” – to allow systemic insecticides to be used in mass quantities, without regulating or labeling them as required under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). EPA does not currently assess adverse effects on the environment and public health caused by widespread use of neonicotinoid insecticides delivered through seeds coated with the insecticides, resulting in widespread exposure to one of the most environmentally damaging classes of chemicals on the market. Tell your Congressional delegation that EPA must fully regulate treated seeds to protect the environment and public health. Pesticide-coated seeds are now ubiquitous, yet their far-reaching impacts on wildlife and human health continue to go unregulated. The introduction and spread of seed-delivered pesticides to major field crops, beginning around 2003, caused a massive increase in total neonicotinoid use nationwide. As of 2011, 34 to 44% of soybeans and 79 to 100% of maize acres were planted with coated seeds, accounting for an astounding 35-fold increase in nationwide neonicotinoid use from baseline rates prior to 2003 (Douglas and Tooker, 2015). Alarmingly, because the national pesticide survey conducted by the National Agricultural Statistics Service fails to […]

(Beyond Pesticides, March 22, 2019) A two-year study, published March 14,  finds that field-relevant contamination with the neonicotinoid insecticide imidacloprid causes reduced body weight and metabolism in white-tailed deer, and – in fawns – mortality. Remarkably, researchers uncovered imidacloprid levels in free-ranging deer a full 3.5 times higher, on average, than the levels in the animals treated in their experiment. These new findings add to the mounting evidence of the hazards posed by current patterns of neonicotinoid use, while evidence of benefits remains sparse. The study, published in Nature Scientific Reports, includes two years of data on the physiological and behavioral outcomes of imidacloprid contamination in 80 white-tailed deer housed in a South Dakota State University captive research facility. Notably, researchers were unable to entirely control imidacloprid levels in untreated deer, most likely due to background contamination from corn- and soy-based feed, and surrounding vegetation infiltrated by runoff from nearby agricultural fields. This background contamination altered, but did not compromise, the analysis. Researchers found that imidacloprid levels detected in the spleens of treated and control animals were significantly predictive of reduced thyroid hormone levels, shorter jawbones, lower activity levels, and higher fawn mortality. Lead authors Elise Berheim, Jonathan Jenks, PhD, […]

(Beyond Pesticides, March 19, 2019) Research is beginning to explain how systemic neonicotinoid insecticides affect often overlooked species of ground nesting bees. While much of the current scientific literature has focused on the impacts of pesticides to bumblebees and honey bees, a study, Chronic contact with realistic soil concentrations of imidacloprid affects the mass, immature development speed, and adult longevity of solitary bees, recently published in Scientific Reports, confirms that wild, soil-dwelling bees are at similar risk. As policy makers consider ways to protect pollinators, this research finds that uncontaminated soil is an important aspect of ensuring the health of wild, native bees. “This is an important piece of work because it’s one of the first studies to look at realistic concentrations of pesticides that you would find in the soil as a route of exposure for bees,” said Nick Anderson, co-author of the study. “It’s a very under-explored route, especially for some of the more solitary species that nest in the ground.” In order to study the impact of neonicotinoids on ground nesting bees, researchers used orchard mason bees and leafcutter bees as proxies, as they are easier to gather and rear in the lab, and have a similar ecology […]

(Beyond Pesticides, March 11, 2019)  We must stop the expanded commercialization of genetically engineered pesticides. The failure of the U.S. Environmental Protection Agency (EPA) to fully evaluate environmental impacts of gene-manipulating pesticides raises serious concerns in light of the agency’s ongoing failure to predict ecological effects of pesticides, such as the dramatic decline of pollinators. With the release of a 2019 peer-reviewed scientific article, Environmental Fate of RNA Interference Pesticides: Adsorption and Degradation of Double-Stranded RNA Molecules in Agricultural Soils, on the potential impact on soil and non-target microorganisms in soil, the study’s co-author, Kimberly Parker, PhD, remarked, “The ecological risk assessment of these emerging pesticides necessitates an understanding of the fate of dsRNA [double stranded RNA] molecules in receiving environments, among which agricultural soils are most important.” This technology, given that it is systemic to the plant and leaves traces in the soil, can cause widespread indiscriminate poisoning—as has been seen with bees, butterflies, birds, and the larger catastrophic decline of insect populations. Tell your members of Congress that the ecological effects of RNAi gene-manipulating pesticides raise serious questions—they have not been fully studied by EPA and, until they are, the agency should issue a moratorium on their release. Previously, […]

(Beyond Pesticides, March 7, 2019) A publication in the journal Environmental Health Perspectives highlights findings from a recent study showing that environmental concentrations of the neonicotinoid insecticides thiacloprid and imidacloprid increase expression of a gene linked to hormone-dependent breast cancer. Authors of the featured study uncovered a pathway through which neonicotinoids stimulate excess estrogen production, known to occur during the development of progressive hormone-dependent breast cancer. In the words of the authors, “Our findings highlight the need for further research to assess the potential impacts of low-dose and chronic exposure to neonicotinoids on endocrine processes affecting women’s health.” The study, published in Environmental Health Perspectives in April 2018 by researchers at the University of Quebec, is not the first to point to a potential link between neonicotinoid exposure and breast cancer. A 2015 study by the same research group revealed that the neonicotinoids thiacloprid and thiamethoxam, along with the herbicide atrazine, induce similar effects in breast cancer cells. In both studies, exposure to neonicotinoids alter promoter activity to induce heightened production of the enzyme aromatase, which is known to stimulate estrogen production and thereby cancer cell proliferation. The recently published study, authored by Silke Schmidt, PhD, brings greater urgency to […]
