(Beyond Pesticides, December 7, 2021) One exposure. That’s all it takes for wild bees to experience declines in reproduction and population growth from neonicotinoid insecticides, according to research recently published in the Proceedings of the National Academy of Sciences (PNAS). This incredible sensitivity is exactly the sort of process that could rapidly drive pollinator species into extinction. It is the sort of finding that one would expect government agencies tasked with protecting the environment to discern. Yet, regulators at the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs have consistently failed to listen and meaningfully respond to the latest science. As this is done, the agency is fully aware that ever more pollinators are slated for endangered status, jeopardizing our agricultural economy, ecosystem stability, and the joy we all gain from watching our favorite pollinators flit about the landscape. Over the course of two years, researchers established a crossed experiment with ground-nesting blue orchard bees (Osmia lignaria). These pollinators, native to North America, overwinter and nest in narrow holes or tubes, making them particularly sensitive to ground-based pesticide applications. Researchers conducted their study during the first year by exposing a group of larval bees to the neonicotinoid imidacloprid through […]

(Beyond Pesticides, November 30, 2021) The chronicle of developments in the glyphosate saga has just grown longer: the California Supreme Court has rejected a request by Bayer AG for review of the August 2021 First District Court of Appeal (San Francisco) ruling, for the plaintiffs, that Monsanto knowingly marketed a product — Roundup — whose active ingredient (glyphosate) could be dangerous. The $87 million in damages awarded to the plaintiffs in the litigation, Alberta and Alva Pilliod, has thus survived Bayer’s challenge. This highest state court decision racks up another loss for Bayer (which now owns the Monsanto “Roundup” brand) — despite its dogged insistence, throughout multiple lawsuits (with many more still in the pipeline), that glyphosate is safe. Beyond Pesticides has covered the glyphosate saga extensively; see its litigation archives for multiple articles on glyphosate lawsuits. Glyphosate has been the subject of a great deal of public, advocacy, and regulatory attention, as well as the target of thousands of lawsuits — particularly since the 2015 declaration by the IARC (International Agency for Research on Cancer) that the compound is a likely human carcinogen. In June 2020, facing approximately 125,000 suits for Roundup’s role in cancer outcomes, Bayer announced a $10 billion […]

(Beyond Pesticides, November 11, 2021) Evidence is building that so-called ‘inert’ ingredients in pesticide formulations are harming pollinators and undermining regulatory determinations that designate products as ‘bee-safe.’ According to a new study published in Scientific Reports, the fungicide Amistar causes lethal and sublethal effects that can be primarily attributed not to its active ingredient azoxystrobin, but to alcohol ethoxylates, a co-formulant, or inert ingredient intentionally added to a pesticide formulation. While the U.S. Environmental Protection Agency (EPA) utilizes a ‘bee advisory box’ on pesticide labels to indicate danger to pollinators, results of this and previous studies on inert ingredients underline how EPA’s ‘cute little bee icon’ is little more than window dressing for massive regulatory failures and a pollinator crisis that has shown no signs of abating. Scientists at Royal Holloway University in London, UK began their study with three packaged colonies of Bombus terrestris, a European bumblebee often bred for commercial use in greenhouses throughout the world. In order to suss out differences in toxicity between the various ingredients in the formulated Amistar fungicide, bees were separated into multiple groups. One group acted as a positive control, and was dosed with dimethoate, a pesticide known to be highly toxic […]

(Beyond Pesticides, November 10, 2021) The diversity and abundance of freshwater aquatic insects plunges when commonly used neonicotinoid (neonic) insecticides leach into waterways, finds research published in the Proceedings of the National Academy of Sciences this month. While this is the latest study exploring the effects of neonicotinoids in the field at real-world exposure levels, it is far from the first to show unacceptable hazards to wildlife and ecological health. As research on neonics piles up, advocates are watching in dismay as regulators at the Environmental Protection Agency (EPA) fail to respond to the science and allow indiscriminate poisoning to continue. To determine how neonicotinoids affect critical aquatic species near the bottom of the food chain, researchers created a series of 36 experimental ditches, split into four groups of nine. One group acted as a control and received no pesticide, and each other group received, 0.1, 1.0, or 10 parts per billion (ppb) of the thiacloprid, a neonic insecticide often cited by industry and regulators as having lower toxicity concerns than other neonicotinoids. Mimicking a pulse that may come from a nearby insecticide application, each group of ditches was dosed every two weeks for a period of three months. Scientists […]

(Beyond Pesticides, October 27, 2021) Declines in pollinator populations throughout the world may result in the loss of tens of thousands of wild flowering plants that rely on their services, according to research published this month in the journal Science Advances. “Our paper provides the first global estimate of how many plant species mostly or completely rely on animal pollinators to make seeds and thus to reproduce,” wrote author James Rodger, PhD, in an article in The Conversation. “We found that it’s about 175,000 plant species – half of all flowering plants. This means declines in pollinators could cause major disruptions in natural ecosystems, including loss of biodiversity.” Pollinators are being threatened with multiple interacting stressors, from climate change, to pesticide use, disease, habitat destruction, and other factors. In the US, an increasing number of pollinators, including iconic species like the American bumblebee and monarch butterfly, are being added or in consideration for listing under the Endangered Species Act. Systemic neonicotinoid insecticides implicated for their earth-spanning hazards to pollinator populations themselves put 89% or more of U.S. endangered species at risk. Many are aware of the fact that pollinators help make available one in three bites of food. Research studies […]

(Beyond Pesticides, October 25, 2021) The Environmental Protection Agency (EPA) is requesting public comments on its draft Biological Evaluations (BEs) for neonicotinoid insecticides imidacloprid, clothianidin, and thiamethoxam by 11:59 pm (EDT) on Monday, October 25, 2021. The BEs will factor into EPA’s registration review decisions on the three bee-toxic insecticides. Written comments must be submitted through Regulations.gov. Please feel free to cut and paste parts of  Beyond Pesticides’ comments (linked here) or cut and paste into Regulations.gov the suggested comment language at the very bottom of this alert.  Tell EPA to protect endangered species from pesticides. EPA’s Biological Evaluations for these highly toxic chemicals make no agency conclusion or recommendation that would trigger a request to initiate formal Endangered Species Act (ESA) §7(a)(2) consultations with the U.S. Fish and Wildlife Service (USFWS) to determine a possible jeopardy finding for the listed species and requisite mandatory use restrictions of the relevant pesticide. This, despite the fact that for imidacloprid the agency’s draft Biological Evaluation made a May Affect determination for 89% of the 1821 species considered and 90% of the 791 critical habitats considered. Strikingly, a May Affect determination was made for 100% of amphibian and avian listed species and their […]

(Beyond Pesticides, October 5, 2021) The U.S. Fish and Wildlife Service (USFWS) will consider listing the American bumblebee (Bombus pensylvanicus) under the Endangered Species Act, according to a notice published in the Federal Register late last month. Earlier this year, the Bombus Pollinator Association of Law Students at Albany Law School and the Center for Biological Diversity petitioned the agency to list the species. USFWS review of the petition indicates that it found “substantial scientific or commercial information indicating that the petitioned actions may be warranted,” and will determine over the next year whether final listing and further protective actions are warranted.  With the American bumblebee experiencing an 89% decline in its population over the last 20 years, scientists and advocates  believe it is critical for USFWS to take steps to protect what remains of this iconic species. At one time, the American bumblebee’s range extended from eastern Canada south through the United States into Florida, and as far west as California. Oregon is the only state in the continental US where the species has never been spotted. Declines are particularly pronounced in the northern part of its range, where recent sightings are nil, and assessments for states like New […]

(Beyond Pesticides, September 17, 2021) Against the backdrop of what The New York Times in 2018 called the “insect apocalypse,” and the dire plight of pollinators in particular, Friends of the Earth (FOE) recently issued its retailer scorecard, which benchmarks “25 of the largest U.S. grocery stores on pesticides, organic offerings and pollinator health”— with the vast majority of retailers failing to protect pollinators. FOE reporting shows some, but far too slow and anemic, progress by corporate actors in enacting pollinator- and bee-friendly policies across both retail sites and supply chains. Such policies, to be genuinely effective and protective of pollinators (and human health), would eliminate or at least dramatically reduce the presence of pesticides in the food supply. The path out of the chemical pesticide quagmire is organic: companies must do more to move suppliers to organic, regenerative production practices, and EPA should be pulling these toxic compounds from the market. Tracking the pollinator policies and enforcement activities of various huge companies yields a useful barometer in monitoring the travel of pesticides to the consumer. Yet the results in the FOE scorecard — e.g., only two of those 25 retailers scored even in the “B” range, and 21 scored […]

(Beyond Pesticides, September 15, 2021) Toxic pesticide use, and glyphosate in particular, degrades the health of freshwater ecosystems by harming species that form the basis of aquatic food chains, according to research published by scientists at McGill University. In a series of studies, scientists investigated how freshwater bacteria and zooplankton were affected by varying levels the weed killer glyphosate, the neonicotinoid insecticide imidacloprid, and nutrient levels. “Because plankton form the foundation of the food chain in freshwater ecosystems, it is very important to understand how plankton communities respond to widely used pesticides,” said Jesse Shapiro, PhD, an Associate Professor in McGill’s Department of Microbiology and Immunology. “Our research shows that the structure of these communities can be impaired under currently acceptable North American water quality guidelines.” Two separate experiments were conducted under similar conditions in order to properly investigate the effects of pesticide exposure on either zooplankton or freshwater bacteria. For both studies, target species were exposed to varying rates of glyphosate, imidacloprid, or both chemicals at either high or low water nutrient levels. Researchers conducted this study by establishing a series of outdoor experimental ponds, intended to mimic freshwater ecosystems by using Lake water and evenly distributing organisms throughout […]

(Beyond Pesticides, September 8, 2021) The U.S. Environmental Protection Agency (EPA) last month released a long-overdue biological evaluation of the three most commonly used neonicotinoid (neonic) insecticides, finding that the chemicals are likely to adversely affect the lion’s share of endangered species and their habitat. While the public may be most familiar with the damage neonics cause to pollinator populations, EPA’s evaluation highlights the widespread, indiscriminate harm scientists throughout the world have been sounding the alarm about for years. Advocates say the findings make it clear that neonicotinoids must be immediately banned from use. Under the Endangered Species Act (ESA), EPA is required to consult with federal wildlife agencies and conduct a biological evaluation of the impacts a pesticide may have on endangered species and their habitats, prior to the agency formally registering the pesticide. This almost never happens. EPA regularly fails to conduct this evaluation, requiring environmental and conservation organizations to sue the agency in order to force compliance with the law.   EPA has been subject to a number of legal challenges over the last decade for its failure to comply with ESA when it registered neonics pesticides. In 2019, Ellis v Housenger (EPA), a lawsuit filed by […]

(Beyond Pesticides, August 30, 2021) As with other actions on pesticides, EPA’s chlorpyrifos decision is filled with exceptions that respond to vested interests seeking to ignore or deflect the science. EPA, since announcing its decision in 1999 to ban “residential” uses of chlorpyrifos, continues to allow the following uses: (i) Residential use of containerized baits; (ii) Indoor areas where children will not be exposed, including only ship holds, railroad boxcars, industrial plants, manufacturing plants, or food processing plants; (iii) Outdoor areas where children will not be exposed, including only: golf courses, road medians, Industrial plant sites; (iv) Non-structural wood treatments including: fenceposts, utility poles, railroad ties, landscape timers, logs, pallets, wooden containers, poles, posts, and processed wood products; (v) Public health uses: Fire ant mounds (drench and granular treatment); (vi) nurseries and greenhouses; and (vii) Mosquito control. These uses are unaffected by EPA’s announcement. We need to finish the chlorpyrifos job. Tell EPA to ban all uses of chlorpyrifos. The collective effort to remove this one chemical is a tremendous feat in eliminating one exposure to a hazardous material for children. Achieving the ban on food uses required an enormously resource-intensive effort at a time in history when we are […]

(Beyond Pesticides, August 19, 2021) Does a science-based, public health-oriented, occupational safety focused, children-concerned, ecologically protective society allow the use of toxic pesticides that are unnecessary to achieve land management, quality of life, and food productivity goals? Should victims of poisoning have to plead with regulators to protect them? Should organizations have to fight chemical-by-chemical to achieve basic levels of protection from individual neurotoxic, cancer causing, endocrine disrupting pesticides? Of course not. But, the U.S. Environmental Protection Agency’s (EPA) announcement that it is stopping food uses of the insecticide chlorpyrifos after being registered 65 years ago provides us with an important opportunity for reflection, not just celebration. The collective effort to remove this one chemical is a tremendous feat in eliminating one exposure to a hazardous material for children. That is the point. The action we’re celebrating required an amazingly resource-intensive effort at a time in history when we are running against the clock in an urgent race to transition our society and global community away from the use of petroleum-based, toxic pesticides—to move to meaningful practices that sustain, nurture, and regenerate life. In this context, let’s put chlorpyrifos in perspective. EPA was forced into its decision by a court […]

(Beyond Pesticides, August 18, 2021) Multinational chemical company Bayer filed a petition with the U.S. Supreme Court this week, seeking a reversal of a lower court verdict that established Bayer liable for damages from the use of its weed killer Roundup. After purchasing Roundup-maker Monsanto in 2018, Bayer has been mired in a deluge of court battles from injured customers throughout the country who assert that their use of the glyphosate-based herbicide resulted in their cancer diagnosis. Bayer, for its part, has consistently lost these court cases. The company’s Supreme Court petition is now regarded as its best and last chance to avert responsibility for the ongoing harm to public health caused by its carcinogenic herbicide. Bayer’s Supreme Court challenge pertains to the Hardeman v. Monsanto case. In that suit, a California court found unanimously in favor of the plaintiff, Edwin Hardeman. Mr. Hardeman told the jury he had used Roundup since the 1980s to spray poison oak and weeds around his property, resulting in his diagnosis of non-Hodgkin lymphoma in 2014. He was awarded $5.27 million, while his punitive damages were ultimately reduced from $75 to $20 million. Bayer is bringing two main arguments to the Supreme court. First, […]

(Beyond Pesticides, August 17, 2021) “If the bee disappears from the surface of the earth, man would have no more than four years to live.” This quote is often attributed to Albert Einstein (although its true origins are unknown), but it begs an important question: What are the consequences to humankind of a world where pollinators are rapidly declining? Modern-day scientists have begun to explore that question, and a group of 20 experts recently published a global-scale assessment of the risks associated with the ongoing worldwide decline of pollinator populations in the journal Nature Ecology and Evolution. While the study experts do not provide such a dire time frame, the message unfortunately is not too far off from the Einstein-attributed quote. “What happens to pollinators could have huge knock-on effects for humanity,” said lead study author Lynn Dicks, PhD from the University of Cambridge, UK. “These small creatures play central roles in the world’s ecosystems, including many that humans and other animals rely on for nutrition. If they go, we may be in serious trouble.” With a study objective of identifying the key drivers and implications for global pollinator decline, a group of 20 pollinator experts from throughout the world […]

(Beyond Pesticides, August 10, 2021) President Biden’s Environmental Protection Agency (EPA), under Administrator Michael Regan, is set to reapprove the highly hazardous herbicide paraquat with fewer protections than those proposed by the Trump administration. Despite strong links to Parkinson’s, and bans on the herbicide in the European Union, China, Brazil, and many other countries, EPA’s press release inexplicably states, “No direct one-to-one alternatives to paraquat are available.” The move is part of a string of actions that have pesticide reform advocates increasingly concerned that the Biden Administration is not living up to his initial promises to improve health and environmental protections. Paraquat is the most toxic herbicide still on the market. As EPA readily admits, one small sip of paraquat can be fatal. Apart from its acute toxicity, chronic exposure to the herbicide is strongly linked to the development of Parkinson’s disease. But its association with Parkinson’s is merely the most well-known health concern – the chemical is a likely carcinogen, harms the reproductive system, and damages organs like the kidney and liver. It is hazardous to birds and bees, and prone to leaching into groundwater, where it disrupts the health of aquatic ecosystems. The Trump administration’s decision to reapprove […]

(Beyond Pesticides, August 9, 2021) What’s going on at the Environmental Protection Agency (EPA)? Last month, Bayer/Monsanto announced it would voluntarily cancel “residential lawn and garden” uses of glyphosate products, “exclusively to manage litigation risk and not because of any safety concerns.” EPA has done virtually nothing to restrict glyphosate/Roundup since the World Health Organization/International Agency for Research on Cancer in 2015 classified the chemical as probably carcinogenic. It is now expected, as with other voluntary cancellations, that EPA will make no health or environmental findings that could affect other uses (e.g., agricultural) of glyphosate, but will accept the action by Bayer/Monsanto. The company refers to its action as “risk mitigation”—that’s risk to the company’s profitability, economic viability, and shareholder investment, not public health or environmental protection. Voluntary actions by the companies are highly compromised and do not include agency determinations or findings—allowing false claims of safety, offering a shield from liability, and unencumbered international marketing. The Biden administration began with high hopes for the environment. Combating climate change is a priority. On his first day in office, President Biden issued an executive memorandum, Modernizing Regulatory Review, that appears to establish a new framework supporting healthy people and ecosystems, as it […]

(Beyond Pesticides, August 4, 2021) Neonicotinoid insecticides applied to nursery plants sold at garden centers kill off wild, solitary pollinators regardless of the amount applied, according to research published in the Proceedings of the Royal Society B. The news is unlikely a surprise for those tracking the science around pollinator declines, but nonetheless a stark reminder of the lack of progress from federal regulators to stop practices that contribute to the ongoing crisis. With new science consistently showing unacceptable hazards to pollinator populations, advocates are urging Congress to take up and pass the Saving America’s Pollinators Act. Since 2006, scientists and beekeepers have singled out neonicotinoids, a class of systemic insecticides, for their role in pollinator die-off and decline. Once applied onto a seed or sprayed on a plant, neonicotinoids distribute themselves throughout the plant’s structure. This causes soft-bodied sucking insects like aphids to be killed when they eat any part of the plant. However, neonicotinoids also make their way into the pollen and nectar the plant produces, as well as the dew drops plants will secrete and pollinators will often use to grab a quick drink. The use of these insecticides on native plants sold at nursery stores throughout […]

(Beyond Pesticides, July 30, 2021) Bayer (Monsanto), the maker of the deadly herbicide glyphosate/Roundup, after hinting in May that it would end the weed killer’s residential uses in the U.S., made it official yesterday. With its announcement to shareholders, Bayer puts an end to residential uses beginning in 2023 and allocates $4.5 billion to cover “the company’s potential long-term exposure” from lawsuits by those harmed by the chemical. At the same time, the company announced it is seeking a U.S. Supreme Court hearing to reverse significant jury verdicts (from $289 million to $2 billion) for individuals who have suffered health damage they tie to glyphosate exposure. Bayer claims that it will argue that federal pesticide law preempts litigation against products that it has registered with the U.S. Environmental Protection (EPA). Similar arguments have been tried before, most notably in Bates v. Dow Agrosciences (2005), and the Supreme Court has found that federal pesticide law does not protect “manufacturers of poisonous substances.” (See more below.) Despite the extensive scientific review (see Pesticide Gateway) of glyphosate/Roundup and a “probable” cancer causing ranking by the World Health Organization/International Agency for Research on Cancer in 2015, Bayer says, “This move is being made exclusively […]

(Beyond Pesticides, July 16, 2021) Recently published research reviews the 2013 Wilsonville, Oregon mass bumblebee die-off from application of the neonicotinoid dinotefuran on 55 linden trees in a big-box-store parking lot. In that single event, the research paper (published in Environmental Entomology) estimates between 45,830 and 107,470 bumblebees from some 289–596 colonies were killed. Reporting on the new study, by Entomology Today, quotes primary conclusions of the co-authors: “Our study underscores the lethal impact of the neonicotinoid pesticide dinotefuran on pollinating insect populations,” and, “It is likely that the vast majority of mass pesticide kills of beneficial insects across other environments go unnoticed and unreported.” As Beyond Pesticides has chronicled, the U.S. and the world are undergoing a pollinator crisis, caused in significant part by agricultural pesticides. Dinotefuran, the neonicotinoid (neonic) that killed those Oregon bumblebees, is used against fleas, thrips, tree-boring caterpillars, emerald ash borers, hemlock woolly adelgids, and in the Oregon case, aphids. Entomology Today (ET) notes that the timing of this particular application could not have been worse: it happened on a warm day when the linden trees were in full flower and the bees out in force. Ironically, it occurred during Nation Pollinator Week. ET pens a […]

(Beyond Pesticides, July 14, 2021) Corteva (formerly DowDupont) is facing a potential class-action lawsuit after several California families filed suit claiming that the use of the insecticide chlorpyrifos around their homes resulted in birth defects, brain damage, and developmental problems in their children. Chlorpyrifos is an organophosphate insecticide that has been linked to a range of health ailments, posing significant hazards particularly for pregnant mothers and their children. The lawsuits come as the U.S. Environmental Protection Agency (EPA) approaches a court-imposed 60-day deadline to decide the fate of the pesticide’s registration. Attorneys for the court cases, filed on behalf of individuals located in four California communities (Fresno, Kings, Medera, and Tulare counties), indicate they intend to pursue class-action status, which would allow additional injured parties to join the lawsuit. The plaintiffs argue that the effects of chlorpyrifos exposure lingers in the agricultural communities where they reside. “We have found it in the houses, we have found it in carpet, in upholstered furniture, we found it in a teddy bear, and we found it on the walls and surfaces,” said Stuart Calwell, lead attorney for the plantiffs. “Then a little child picks up a teddy bear and holds on to it.” […]

(Beyond Pesticides, July 13, 2021) Bumblebees exposed to pesticides and pathogens display changes in gene expression that can be pinpointed and analyzed by cutting edge research tools, according to scientists at York university, who utilized the new technique in a study published in Molecular Ecology. This form of next-generation gene sequencing is part of a growing field of science known as conservation genomics, in which entire animal genomes are sequenced to determine conservation problems. “Next-generation sequencing is a totally new way to think about why bees are declining, which could revolutionize conservation biology,” says study coauthor Amro Zayed, PhD, associate professor in biology at York. “We’re looking directly at bee tissues  to try and get clues to the stressors that are affecting this bee. I think this is a gamechanger for sure. With a single study, we are able to implicate a couple of really obvious things we’ve talked about for years – pathogens and pesticides – in the case of Bombus terricola.” Researchers focused on Bombus terricola – the yellow banded bumblebee, as its range has declined significantly over the last two decades. The bumblebee was once common throughout the eastern and midwestern part of the U.S. and Canada, […]

(Beyond Pesticides, July 12, 2021) During Pollinator Week 2021 in June, U.S. Representatives Earl Blumenauer (D-OR) and Jim McGovern (D-MA) reintroduced the Saving America’s Pollinators Act (SAPA) to reverse ongoing declines in wild and managed pollinators. New data released in June for 2020-21 documents the second highest honey bee losses in 15 years. SAPA uses the latest scientific research and perspectives to ensure that pollinators are protected. The bill suspends the use of neonicotinoid (neonic) insecticides and other pesticides harmful to bees and other pollinators until an independent board of experts determines that they are safe to use, based on a strong scientific assessment. Ask your elected representative in Congress to support pollinators by cosponsoring Saving America’s Pollinators Act (SAPA). If they are already a cosponsor, use this occasion to thank them for their leadership on this critical issue. “Without our world’s pollinators, the world would be a very different place. These bees, butterflies, hummingbirds, and other creatures are essential elements of our food system. Losing them means we risk losing the very food we put on our table,” said Rep. Blumenauer. “We must use every tool at our disposal to provide pollinators with much-needed relief from bee-toxic pesticides and monitor […]

(Beyond Pesticides, July 2, 2021) The second highest bee loss in 15 years has reported by the Bee Informed Partnership (BIP) in its 2020–2021 National Colony Loss and Management Survey, released on June 30. For the “winter” period of October 1, 2020 through April 1, 2021, approximately 32% of managed bee colonies in the U.S. were lost. This represents an increase of 9.6% over the prior year’s winter loss and is roughly 4% higher than the previous 14-year average rate of loss. For all of the past year (April 1, 2020 to April 1, 2021) the colony loss was 45.5%. Beyond Pesticides has covered the related issues of Colony Collapse Disorder (CCD), the ongoing and devastating impacts of pesticides on bees and other pollinators, and the larger context of what some have called the “insect apocalypse.” These recent BIP data appear to indicate that “we,” writ large, are failing to remedy these problems. Three out of four food crops globally depend on pollinators, at least in part. Commercially kept bees account for a significant portion of pollination of some U.S. crops; almonds are the leading crop, followed by apples and melons. The commercial bee business is huge — a $691 million […]
