(Beyond Pesticides, September 20, 2019) The actual utility of pesticides to achieve their purported goals is an under-recognized failing of the regulatory review of pesticide compounds for use. A study published in Scientific Reports now exposes the faulty assumptions underlying the use of neonicotinoids — the most widely used category of insecticides worldwide. The study demonstrates that use of neonicotinoids (neonics) to treat seeds — a very common use of these pesticides — actually provides negligible benefits to soybean farmers in terms of yield and overall economic benefit. The U.S. Environmental Protection Agency (EPA) should take notice, and consider that efficacy ought to have a role in the agency’s evaluation of pesticides for registration. Neonicotinoids are systemic pesticides that move through a plant’s vascular system and are expressed in pollen, nectar, and guttation droplets (drops of sap exuded on the tips or edges of leaves of some vascular plants). They can also persist in the environment — in soil and water — for extended periods. Neonics are applied to seed, as well as to crop soils and to plant foliage. Corn and soybean seed treatments represent the largest uses of neonics in the U.S.: for somewhere between 34% and 50+% […]

(Beyond Pesticides, September 17, 2019) The poisonous farm fields migratory birds forage on during their journey reduce their weight, delay their travel, and ultimately jeopardize their survival, according to new research published in the journal Science.  Like their effects on pollinator populations, neonicotinoid insecticides generally are not killing migratory songbirds outright, but instead precipitating a cascade of sublethal impacts that reduces their fitness in the wild. As the authors told Environmental Health News, the study is a call not simply to ban neonics or one class of chemical, but to change the entire farming system toward more sustainable bird and bee-friendly practices. Using new technology, this study was not only able to dose wild-caught songbirds (white-crowned sparrows), but also track their migration route using automated telemetry. Apart from the control group that received no pesticide exposure, sparrows were treated at levels well below the median lethal dose (3% of the lethal dose in the ‘low’ exposure group and 10% within the ‘high’ exposure group), and permitted to continue on their migratory path. These are exposure amounts similar to a songbird accidentally ingesting a few treated seeds, according to the study. Within six hours, both the ‘low’ and ‘high’ exposure group […]

(Beyond Pesticides, September 11, 2019) Germany is the latest entity to take action on getting glyphosate-based pesticides out of the marketplace. Chancellor Angela Merkel has announced that, beginning in 2020, the country will phase out herbicides that contain glyphosate by the end of 2023. The phase-out will occur through a series of scheduled reductions in amounts allowed for use, with a goal of a 75% reduction over the next four years. The announcement comes after “nation-wide protests and demands from [Merkel’s] junior coalition partner, the Social Democrats, for more decisive action on environmental issues.” This action stands in telling contrast to the U.S. Environmental Protection Agency’s (EPA’s) repeated failures to protect people, ecosystems, and our food supply, from this toxic compound. The German government also plans to oppose any European Union (EU) request for renewal of licensing of these herbicides, according to the environment ministry. Bayer AG, maker of glyphosate-based herbicides and owner of original manufacturer Monsanto, has pushed back, saying that the government is “getting ahead of itself” by banning glyphosate-based herbicides prior to any decision by the relevant EU authority, and that EU laws disallow unilateral decisions by member states. (Pesticide licensing decisions lie with EU governance in Brussels, […]

(Beyond Pesticides, September 3, 2019) Brazil’s environment is under siege, as President Jair Bolsonaro has approved hundreds of new toxic pesticides this year and gutted watchdog environment agencies. Among the many dreadful results, news reports indicate that between December 2018 and March 2019, Brazilian beekeepers found more than 500 million dead bees. As the Amazon burns, Indigenous activists are calling on the world to help, and Beyond Pesticides is responding by promoting a boycott started by a Swedish supermarket owner: #BoycottBrazilianFood. Pledge to #BoycottBrazilianFood, and ask major U.S. supermarkets to do the same. The Amazon rainforest is the world’s biggest terrestrial carbon sink, and home both to the planet’s richest biodiversity and approximately 400 indigenous tribes. The country has 2300 pesticides registered for use; a total of 290 new toxic pesticides have been approved as of late August 2019. Swedish supermarket owner Johannes Cullberg started an international boycott in response to Brazil’s approval and use of hazardous pesticides in food production. #BoycottBrazilianFood began in June of 2019 when the total of newly registered pesticides stood at 197. Cullburg declared, “We need to stop (the president) Bolsonaro, he’s a maniac.” The boycott prompted a response from the Brazilian embassy, stating, “…the Embassy wishes to inform […]

(Beyond Pesticides, August 27, 2019) The U.S. Environmental Protection Agency (EPA) is the subject to a new legal challenge from environmental groups after approving the use an insecticide shown to be highly toxic to bees and other pollinators.  The lawsuit, filed in the 9th Circuit Court of Appeals by the Center for Biological Diversity and Center for Food Safety, aims to stop the use of sulfoxaflor on more than 200 million acres of crops. As EPA under the Trump administration has become increasingly emboldened to fight for industry priorities, concerned organizations and people are responding by supporting legal challenges and working to pass policies that truly protect wildlife and the environment. According to EPA’s ecological risk assessment for sulfoxaflor, the chemical is “very highly toxic” to bees. A study published last year in the journal Nature found significant concerns with the chemical’s ability to harm already declining pollinator populations. “There is an urgent need to pre-emptively evaluate the potential sub-lethal effects of sulfoximine-based pesticides on pollinators, because such effects are rarely detected by standard ecotoxicological assessments, but can have major impacts at larger ecological scales,” the authors wrote. EPA had already run in to legal problems associated with its registration […]

(Beyond Pesticides, August 23, 2019) The Office of the Inspector General (OIG) for the U.S. Environmental Protection Agency (EPA) recently released a report criticizing EPA’s oversight of states’ Managed Pollinator Protection Plans (MP3s). OIG conducted an audit, on which the report is based, to evaluate agency performance in overseeing MP3s, voluntary plans adopted at the state level with the goal to “reduce pesticide exposure to pollinators (generally, honey bees managed and contracted out to growers for pollination services) through timely communication and coordination among key stakeholders.” The report’s findings include the following: EPA has no means to evaluate the national impact of MP3s. The agency has not developed a strategy to use data from a planned fall 2019 survey (see more below on the AAPCO/SFIREG/EPA survey) to evaluate either the national impact of MP3s or the agency’s support of state MP3 implementation efforts. EPA focuses primarily on acute risks (those that occur during a single exposure to a specific pesticide), and gives insufficient attention to chronic exposures to pesticides and to native pollinator protection activities. The history of the MP3 program starts in 2014, when President Obama issued a memo establishing a Pollinator Health Task Force (PHTF), directing federal agencies […]

(Beyond Pesticides, August 15, 2019) An article in the journal Plos One, “An assessment of acute insecticide toxicity loading (AITL) of chemical pesticides used on agricultural land in the United States,” shows that recent shifts in insecticide use—from organophosphates and carbamates to synthetic pyrethroids and neonicotinoids—have made a large contribution to the ongoing insect apocalypse. This shift to insecticides that target insects based on both selective toxicity and delivery method occurs within a context of shrinking habitat and biodiversity. The study, by Michael DiBartolomeis, PhD, Susan Kegley, PhD, Pierre Mineau, PhD, Rosemarie Radford, and Kendra Klein, PhD, presents a measure of acute insecticide toxicity loading that incorporates acute toxicity, quantity used, and the rate at which the insecticide degrades. Goulson et al. applied a similar measure in Great Britain that did not incorporate the rate of degradation. Both studies use the median lethal dose (LD50) to honey bees as a measure of acute toxicity and calculate the potential number of bee deaths based on the number of lethal doses of various insecticides applied in the field. In both cases, researchers used toxicity estimates for honey bees because they are widely available. Other insects may be more or less sensitive. The […]

(Beyond Pesticides, August 13, 2019) The U.S. Environmental Protection Agency (EPA) is refusing to approve product labels that disclose that the herbicide glyphosate may cause cancer, according to a press release published last week. The move comes after the state of California listed glyphosate on its Prop 65 list of chemicals known to cause cancer, birth defects or other reproductive harm. Health advocates are condemning the decision as the latest in a long string of EPA actions aimed at benefiting industry at the expense of consumer and public health. Many are concerned that the incessant stream of industry-friendly decisions is eroding public trust in the agency and its ability to act as an independent regulator. While a state judge gave the Prop 65 warning labels the go-ahead, a prior ruling from U.S. District Court Judge William Shubb in Sacramento placed a preliminary injunction on the California requirement that remains in place today. The state added glyphosate to its Prop 65 list after the International Agency for Research on Cancer (IARC) designated the chemical as a group 2A carcinogen.  Under Prop 65, California regulators are required to provide “clear and reasonable” warning labels when any one of four requirements in the […]

(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 22, 2019) The U.S. Environmental Protection Agency (EPA) will permit the continued use of a known neurotoxic insecticide on the food the Americans eat, the agency announced yesterday in response to a lawsuit filed by public health groups. Health advocates say the move to continue chlorpyrifos use is the latest example of the agency working to protect the profits of industry over the health of Americans. “By allowing chlorpyrifos to stay in our fruits and vegetables, Trump’s EPA is breaking the law and neglecting the overwhelming scientific evidence that this pesticide harms children’s brains,” said Patti Goldman, an attorney for Earthjustice. “It is a tragedy that this administration sides with corporations instead of children’s health.” Under a lawsuit filed in the 9th Circuit US Court of Appeals, EPA had 90 days to provide a justification for why the pesticide should remain on the market. EPA denied the petition yesterday, and rather than providing positive justification for continued use of the chemical, attacked the sound science claimants urged the agency to consider as “not…valid, complete, and reliable.” In the absence of EPA action, several states are leading in the protection of their residents by rejecting the agency’s determination regarding […]

(Beyond Pesticides, July 18, 2019) Pesticide products containing the weed killer dicamba become more volatile and drift-prone in hot conditions and when tank-mixed with glyphosate, according to a recent study conducted by scientists at the University of Tennessee. The findings help explain rampant complaints from farmers in the South and Midwest experiencing crop loss and economic hardship as a result of drift from new dicamba products, which are formulated with glyphosate for use on genetically engineered (GE) cotton and soy. While states have taken the lead in regulating the use of GE dicamba products, top political officials within Administrator Andrew Wheeler’s EPA overruled the findings from agency scientists urging larger buffer zones to protect neighboring crops and farm fields. During a 60-hour window, scientists applied various GE dicamba products (Clarity and XtendiMax) over a range of temperatures and took air samples. As temperatures increased, so did the volatilization and drift of dicamba, even in formulations touted as “low volatility.” Adding glyphosate to the mixture produced stark results, increasing concentrations of dicamba in the air up to nine times compared to dicamba alone. Tom Mueller, PhD, a professor in the UT Department of Plant Sciences, stated in a press release that […]

(Beyond Pesticides, July 15, 2019)  On Friday, Maryland’s highest court upheld the right of local governments to restrict the use of toxic lawn care pesticides more stringently than the state. By denying an appeal from the pesticide industry’s challenge to a lower court ruling, the Maryland Court of Appeals has made official Montgomery County’s 2015 Healthy Lawns Act, which prohibits toxic pesticides from being used on public and private property for cosmetic purposes. “This long-awaited decision affirms local democratic decision making to protect health and the environment, upholding the first U.S. county law to ban toxic pesticides on private and public property,” said Jay Feldman, executive director of the organization Beyond Pesticides. “The law, now in force, will bring critical health protections for pregnant mothers, children and other vulnerable residents in Montgomery County, and safeguard sensitive wildlife species like pollinators.” The decision by the Maryland Court of Appeals upholds local democratic decision making in the face of a challenge by industry groups representing lawn care companies and chemical manufacturers. The chemical industry has fought for nearly three decades to suppress the right of local governments in the U.S. to protect public health and safety with pesticide law, having successfully lobbied […]

(Beyond Pesticides, July 12, 2019) The U.S. Department of Agriculture (USDA) announced, on Saturday, July 6 that it would suspend indefinitely the data collection for its Honey Bee Colonies survey and report. The move came, tellingly, less than three weeks after the Environmental Protection Agency (EPA) once again approved “emergency” uses of the pesticide sulfoxaflor, a bee-killing compound similar to the notorious neonicotinoids, insecticides that contribute significantly to the phenomena of pollinator collapse (“colony collapse disorder”) and massive insect loss (“insect apocalypse”) that are underway worldwide. Sulfoxaflor is one of the many toxic pesticides that threaten honey bees, which are critical pollinators responsible for one-third of the food we humans consume. Permitting its use and then ceasing to collect and report data on the status of honey bees that are likely to be impacted is not only a recipe for kneecapping the study of bee decline and imperiling the food supply, but also, another example of the corruption for which this administration is infamous. As The Huffington Post reported, “Critics say the USDA’s move is the latest evidence of the Trump administration’s war on science, and its goal of suppressing information about serious environmental harms increasing under Donald Trump’s presidency.” Union […]

(Beyond Pesticides, June 8, 2019) Scientists studying the precipitous decline in populations of monarch butterflies are searching for causes, and pesticide use is one of the factors under their (figurative) microscopes. Purdue University entomology professor Ian Kaplan, PhD and doctoral student Paola Olaya-Arenas recently turned their attention to a poorly studied potential factor — exposure during monarchs’ larval stage to non-target pesticides on their primary host plant and food source, common milkweed (Asclepias syriaca). In Frontiers in Ecology and Evolution, the researchers report finding evidence of 14 different agricultural pesticides on milkweed near Indiana farm fields, including neonicotinoids clothianidin and thiamethoxam, the pyrethroid deltamethrin, and imidacloprid in a few samples. The research team’s primary aim was to identify and measure the range of pesticides to which monarch caterpillars might be exposed, or which they might consume, on milkweed plants in agricultural landscapes. Secondarily, they hoped to learn how pesticide presence varies with distance between milkweed plants and nearby agricultural sites. In the subject Indiana environs, where corn and soybeans are dominant crops, the study found neonicotinoid residues on milkweed, particularly those of the active ingredients in clothianidin and thiamethoxam. They note, “Although seed treatment data are no longer reported for U.S. […]

(Beyond Pesticides, July 5, 2019) This is a story about a chemical pesticide, a fungicide, in wide use for which the mode of action, i.e., the ability to cause harm, has not been fully understood. It is not a story unique to this pesticide. Rather, it is an important story to consider when deciding to use a pesticide or allowing a pesticide to be used. The question is whether the chemical could be broadly problematic beyond the target organisms, in this case fungi? In its coverage of a study published in March, the American Association for the Advancement of Science publication, EurekAlert, reported that, “The ability of [the fungicide] fludioxonil to act on a sugar-metabolizing enzyme common to all cells, and to produce the damaging compound methylglyoxal, may mean that the pesticide has more potential to harm non-fungal cells than previously thought. Although fludioxonil has been deemed safe for use, the authors . . . suggest that the effects of this widely used pesticide has upon animals be re-examined.” The research study, published in March in Scientific Reports and led by T. Tristan Brandhorst, PhD (in the lab of Dr. Bruce Klein at the University of Wisconsin–Madison and UW School of […]

(Beyond Pesticides, June 28, 2019) As is the case in many countries, the conversation about the use of pesticides has been especially vigorous in the past few years. Switzerland is a case in point: it is undergoing deep scrutiny of pesticide use, and the UN Special Rapporteur on Toxics, Baskut Tuncak, has now said publicly that pesticide companies’ behavior is “seriously deficient” regarding human rights (especially those of children), and that the Swiss government should act more aggressively to phase out use of these hazardous chemicals. Recently, the pesticide conversation has ratcheted up several notches, not only in the U.S., but also globally, due to greater public awareness of the health and environmental threats of pesticide use, more and more research underscoring those threats, and pointedly, the cascade of litigation against Monsanto (now owned by Bayer) for harm to individuals who have used its glyphosate-based products. Public awareness in Switzerland is also mounting in response to global developments, to recent discoveries that small streams in Swiss agricultural areas are heavily polluted with pesticides, and to broadening recognition that pesticides are linked to a plethora of harms to human health, pollinators, water, farmworkers, wildlife, ecosystems and biodiversity, and more. In 2017, a UN […]

(Beyond Pesticides, June 27, 2019) A review of scientific literature urges for swift societal action on the collapse of insect populations worldwide, according to authors of a study. The authors point out that while there is a need for more research on the extent of the phenomenon as well as causal factors, there is currently sufficient evidence to spur and inform transformational policy in response to a definite worldwide crisis. The paper, Declines in insect abundance and diversity: We know enough to act now, provides a run-down of actions to take—from national policy to apartment balconies. Recent reports name alarming drops in insect diversity and abundance, prompting the ominous label of “insect apocalypse.” Almost half of all insect species are rapidly declining, and a third are being threatened with extinction. The authors state, “Although there has been some criticism of specific studies, the overall trend is clear and the broad geographic reach is perhaps the most dire feature of the current crisis, as assessments from all continents except Antarctica reveal declines.” The main culprits of insect demise are habitat loss and degradation, pesticides, and climate change. The authors note that it is less critical, at this juncture, to focus on […]

(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 18, 2019) As the New York Times wrote in November 2018, “The Insect Apocalypse is Here.” But can we reverse it? Pollinator Week this year is overshadowed by a greater, all-encompassing crisis that spans the entire insect world. Scientists and researchers have identified three broad contributors to the crisis: pesticide use, habitat destruction, and climate change. It is evident that multi-national agrichemical industries, companies like Bayer Monsanto, DowDupont, Syngenta, and the umbrella organization Croplife, that pervade our food system share much of the blame. But through public pressure and consumer choice, we can shift towards alternative products and practices, improve biodiversity, and begin to repair the damage done by industrial agriculture. Pesticide Use Industrial agricultural often places pesticide use as the first tool in the toolbox of possible fixes to pest problems. This leads to a range of deleterious impacts both up and down the food chain, as both prey and predator succumb to the effects of broad spectrum pesticides. Although it makes common sense that pesticides kill off more than their target insect, the scale of the problem was not realized until a study was published in PLOS One by German researchers. It found, after 27 […]
