(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 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 16, 2021) The failure of the U.S. Environmental Protection Agency (EPA) to meet its statutory responsibility to protect people and wildlife from the dire consequences of exposure to endocrine-disrupting chemicals must end. The Office of the Inspector General (OIG) for EPA has issued a damning report on the agency’s progress in protecting the population from potentially damaging endocrine disruption impacts of exposures to synthetic chemical pesticides (and other chemicals of concern) that shows the situation to be even worse than previously reported. The OIG’s summary statement says, “Without the required testing and an effective system of internal controls, the EPA cannot make measurable progress toward complying with statutory requirements or safeguarding human health and the environment against risks from endocrine-disrupting chemicals.” As a result, according to the OIG, “we have yet to see EPA use endocrine disruption findings in pesticide registration decisions.” Tell EPA that pesticide use cannot continue without findings of no endocrine disruption. Over recent decades, evidence has mounted showing that many pesticides interfere with hormones—and are therefore endocrine-disrupting chemicals (EDCs). In 1996, the promise of screening pesticides for endocrine disruption generated support from environmentalists and public health advocates for the Food Quality Protection Act […]

(Beyond Pesticides, August 13, 2021) Across the pond in the UK, two years of trials with spring and winter wheat varieties have shown, according to the Farmer Scientist Network (FSN), which conducted the study as Crop Health North, that so-called “biopesticides,” alone or in combination with conventional pesticides, can be useful in generating yield and grain quality comparable to those obtained through use of conventional “crop chemistry” (aka, synthetic chemical pesticides). According to Beyond Pesticides Executive Director Jay Feldman, biopesticides are a “mixed bag,” generally poorly understood, and defined differently by various entities and stakeholders. He notes that the term can be misleading and mixes contradictory approaches, adding that, “It’s troublesome when we continue to look for product replacements or substitutions for agricultural practices that are clearly ineffective, and in the process avoid the changes necessary to transition to organic practices,” which represent the real, long-term solution to the problems efforts such as these trials seek to remedy. The project was sponsored and supported by the Yorkshire Agricultural Society (YAS) through the European Innovation Partnership (EIP-AGRI). YAS collaborated with universities, farmers, research institutes, agricultural organizations, and technology and food testing centers to conduct trials on three farms in the north of […]

(Beyond Pesticides, August 11, 2021) Multiple stressors, including pesticides, parasites, and poor nutrition, act synergistically to increase the risk of bee mortality, according to a meta-analysis recently published in the journal Nature. The findings are yet another indictment of the U.S. pesticide regulatory system’s ability to protect pollinators, as the authors note that their results, “…demonstrate that the regulatory process in its current form does not protect bees from the unwanted consequences of complex agrochemical exposure.” As scientific community continues to confirm the dangers of pesticides and other anthropogenic stressors to pollinators, it remains up to advocates and other concerned residents to get regulators and policymakers to listen to and act on these critically important conclusions.   Scientists aimed to evaluate how combinations of multiple pesticides, parasites, and lack of floral resulted in bee death or subchronic effects that impacted overall fitness (reproductive ability, colony health, etc), behavior, parasite load, or immune response. The effects of multiple stressors can be characterized as antagonistic when stressors cancel themselves out, additive when the impacts seen are what would be predicted when summing the individual effects, and synergistic when the effects are multiple times more harmful than what would be predicted additively. To […]

(Beyond Pesticides, August 6, 2021) The organization Public Employees for Environmental Responsibility (PEER) has filed complaints with the U.S. Environmental Protection Agency’s (EPA’s) Office of the Inspector General (OIG) on behalf of four EPA whistleblower scientists. The scientists maintain that during the Trump administration, risk assessments for both new and existing chemicals were improperly changed by agency managers to eliminate or reduce calculations of risks; further, they assert that some of this behavior at EPA is ongoing. Beyond Pesticides recently covered a report in The Intercept, written by Sharon Lerner, that examined the multiple aspects of undue industry influence on the regulation of pesticide chemicals. The PEER complaints address regulation of other kinds of toxic chemicals, but Beyond Pesticides maintains that some of the problems the whistleblowers identify hold true for EPA’s Office of Pesticide Programs, as well. Appropriately enough, the nation again recognized National Whistleblower Appreciation Day on July 30. In 1989, Congress established the Whistleblower Protection Act (WPA) to protect federal employees who report lawbreaking or other violations of rules or regulations; waste of funds; abuses of authority; gross mismanagement; or substantial and specific danger to public health or safety. In 2012, Congress passed the Whistleblower Protection Enhancement […]

(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 26, 2021) Despite federal law that directs the U.S. Environmental Protection Agency (EPA) to register pesticides only if they do not cause unreasonable adverse effects on humans or the environment, EPA allows pesticides known to cause many adverse effects on humans and the environment. These include health effects such as asthma, autism and learning disabilities, birth defects and reproductive dysfunction, diabetes, Parkinson’s and Alzheimer’s diseases, and several types of cancer—and environmental effects such as decimation of pollinator populations, direct and indirect killing of wildlife, reducing carbon sequestration in the soil, and poisoning air, water, and land. The risks are particularly high for farmworkers and fenceline communities. Why does EPA consider these effects “reasonable” when the pesticides are not necessary to achieve pest management or prevention goals? Tell EPA not to allow unnecessary pesticide risks. When evaluating pesticide registration applications, EPA does not require data demonstrating “benefits” against which these risks may be weighed. That kind of calculation only takes place years down the line, if EPA believes there is reason to consider canceling a pesticide’s registration. On the other hand, the existence of organic producers fueling $62 billion in organic sales in the U.S., with virtually all […]

(Beyond Pesticides, July 23, 2021) The Rockefeller Foundation has just published a report, True Cost of Food: Measuring What Matters to Transform the U.S. Food System, which identifies the real-but-under-recognized downsides of the U.S. food system. The report notes that, for all its reputed bounty, the food system “comes with hidden costs — to our health, to our climate,” and to the many people who make sure that food reaches the population. The report calls for a true accounting of the costs of food in the U.S. Beyond Pesticides welcomes the broad framework of the report, but notes that a true accounting would necessarily include the costs of the externalities of conventional agriculture, including those related to pesticides: the costs of pollution and its cleanup (when that even happens), of lost pollination and biodiversity, of lost productivity from illness, and of health care costs related to pesticide use. Remarkably, for all its repetition of deleterious impacts on climate, biodiversity, and health, the report barely mentions either pesticides’ roles in causing such impacts, or the clear solution to so many of the negatives in the food system — organic, regenerative agriculture. The report’s economic analysis applies a true cost accounting (TCA) […]

(Beyond Pesticides, July 22, 2021) A new study published in the Journal of Medical Entomology finds black-legged ticks (Ixodes scapulari) in New York are developing potential resistance to widely used tick-control pyrethroid insecticide, permethrin. The study suggests continuous use of area-wide, 4-poster devices (devices that attract deer and then apply pesticide to their head, ears, and neck) to apply insecticide treatments on deer to control tick populations promotes resistance. Resistance is an ever-present issue among chemical compounds (i.e., antibiotics, antimicrobials, pesticides) used in medicine and agriculture, and threatening the ability to prevent disease outbreaks, such as Lyme disease. Furthermore, increasing populations of rodent and mammalian hosts, in addition to warmer temperatures prompted by the climate crisis, allows for disease-carrying ticks to flourish. Lyme disease is the most common vector disease and a primary concern for the general population. Therefore, studies like this highlight the need to assess resistance among disease-vector pest populations regardless of pesticide application methods. The researchers note, “Permethrin susceptibility of tick populations should be monitored from other 4-poster control areas so that guidelines for managing pesticide resistance in the field can be developed.” Four-poster devices impart selective pressure on tick populations influencing reproduction and natural extinction of species. However, like mosquitoes, a subpopulation of ticks […]

(Beyond Pesticides, July 20, 2021) Chlorpyrifos exposure results in the expression of genetic mutations associated with autism spectrum disorder in a laboratory model, finds research published in Environmental Health Perspectives by scientists at Johns Hopkins Bloomberg School of Public Health. “This is a step forward in showing an interplay between genetics and environment and its potential role for autism spectrum disorder,” says study lead Lena Smirnova, PhD, a research associate in the Department of Environmental Health and Engineering at the Bloomberg School. The findings support reams of research already conducted that show strong associations between autism and exposure to hazardous environmental stressors like toxic pesticides. Scientists conducted their study using a ‘brain organoid’ model, which is essentially a cluster of cells artificially grown in the lab from stem cells in order to mimic a developing human brain. These tests provide certain benefits over animal testing, as they are more relevant to human disease, and can be performed faster with less cost. The organoid model also represents an improvement on typical 2d cell-based models, increasing cell survival, shelf-life, and thus providing opportunity to model for later stages of brain development. Brain organoids in this study carried a gene called CHD8, which […]

(Beyond Pesticides, July 19, 2021) As yet another study, “Early life multiple exposures and child cognitive function: A multi-centric birth cohort study in six European countries,” draws attention to the benefits of organic food for the learning young mind, it is important that schools provide organic food to students. The study, conducted by Spanish researchers based at the Barcelona Institute for Global Health, looks at a totality of all environmental hazards that children encounter, rather than individual lifestyle factors. As study co-author Jordi Júlvez, PhD, notes, “Healthy diets, including organic diets, are richer than fast food diets in nutrients necessary for the brain, such as fatty acids, vitamins and antioxidants, which together may enhance cognitive function in childhood.” Tell your governor and USDA/Food and Nutrition Service to provide organic school lunches and information for parents. Researchers find that children who eat organic food display higher scores measuring fluid intelligence and working memory. Lower scores on fluid intelligence tests are associated with children’s fast food intake, house crowding, and exposure to tobacco smoke. Lower scores on working memory tests were associated with exposure to poor indoor air quality. This study adds to prior research finding that eating a conventional, chemical-intensive diet increases […]

(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 15, 2021) A study by ETH Zurich finds multi-crop (mixed culture) farmlands, which include a diverse array of crops, produce higher biomass and seed yields than single-crop (monocultures). Monocultures are most prevalent among arable farmland as commercial industrial farming uses this practice to increase sowing, managing, and harvesting efficiency for higher yields. However, less crop diversity leads to higher, more intensive pesticide use as pests favor the consistent food availability monocultures provide. An increase in toxic chemical use threatens human, animal, and environmental health, as well as food security. Ecological research already finds a positive association between plant diversity and biomass productivity in grasslands and meadows. In addition, a University of California, Santa Barbara study demonstrates that crop diversity in commercial agriculture is just as essential to supporting a stable biological system as plant diversity on non-commercial landscapes (i.e., grasslands/meadows). Therefore, this research highlights the need to develop policies that help farmers and global leaders make more knowledgeable decisions regarding crop diversity to sustain yield without toxic pesticides. The researchers note, “While crop diversification provides a sustainable measure of agricultural intensification, the use of currently available cultivars [(plant varieties for selective breeding)] may compromise larger gains in seed yield. We, therefore, advocate regional […]

(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 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 9, 2021) The investigative online publication The Intercept has turned its attention to the current and historical role of industry in distorting, undermining, and outright suppressing the protective function of the U.S. Environmental Protection Agency (EPA) with regard to pesticide exposures. The subsequent reporting — “The Department of Yes: How Pesticide Companies Corrupted the EPA and Poisoned America” — is a devastating chronicle of the theme and particulars that Beyond Pesticides has covered for years. That is, that EPA has repeatedly disregarded its charge to protect human and environmental health in favor of enabling industry to continue its chemical experimentation on the populace and on the nation’s multiple natural resources. This pattern must change if the agency is to enact its mission and the public is to be protected. The Intercept interviewed more than 24 people with expertise on the regulation of pesticides, including 14 who have worked in EPA’s Office of Pesticide Programs (OPP). The chief takeaway from those interviews, as written by reporter Sharon Lerner, is that EPA “is often unable to stand up to the intense pressures from powerful agrochemical companies, which spend tens of millions of dollars on lobbying each year and employ many […]

(Beyond Pesticides, July 08, 2021) A Portland State University (PSU) study finds oysters of varying distances from wastewater discharge pipes along the Oregon and Washington state coast contain low levels of chemical contaminants. Although wastewater treatment facilities clean water draining from sinks and toilets, the process does not adequately remove all contaminants. The process can leave behind pharmaceutical drugs and personal care products (e. g., shampoos, make-up, deodorant) residues in treated water. PSU has already found that pesticides from the forestry industry threaten clams, mussels, oysters (bivalves) along the Oregon coast. Marine ecosystem pollution is difficult to track and measure, and pesticide regulations can invoke variations in water quality requirements through discrepancies in buffer zones and application concentrations. The combined presence of pesticides, medicine, and personal care products in aquatic environments has direct implications for species and ecosystem health and indirect consequences for human well-being. Therefore, studies like this can help government and health officials develop strategies to reduce the number of chemicals entering aquatic ecosystems, with researchers noting officials can “better understand whether contaminant exposure affects oyster condition.” Researchers wanted to evaluate how proximity to wastewater facilities affects variations in aquatic pollution. Thus, scientists transplanted one-week-old Pacific oysters along the Oregon and […]

(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 […]

(Beyond Pesticides, July 1, 2021) Yellow fever mosquitoes (Aedes aegypti) are evolving resistance to the pyrethroid insecticide permethrin, according to a study published by Colorado State University, highlighting the need to adopt ecologically-based mosquito management. Widespread, intensive use of the pesticide in mosquito control has allowed genetic mutations to persist among these mosquito populations, causing subsequent resistance to permethrin. Pyrethroids are one of the few remaining classes of insecticides available to control yellow fever mosquitos, and resistance threatens the ability to prevent disease outbreaks with chemical-intensive methods. Yellow fever mosquitoes are a vector for numerous untreatable diseases in humans, including dengue, chikungunya fever, and Zika viruses. Hence, this study highlights the significance of addressing pest resistance to pesticide control, particularly to mitigate disease exposure and effects. The researchers note, “This knowledge can help scientists understand how mosquitoes have evolved resistance and when a population can no longer be controlled with permethrin. This understanding will be necessary to develop tools to support future insecticide management strategies.” Researchers sequenced the genome of resistant and knockdown (either recovered or dead) mosquitoes after permethrin exposure using a bottle bioassay. The aim was to identify genomic variants/biomarkers associated with specific resistance mechanisms. Two common pyrethroid resistance mechanisms occur among […]

(Beyond Pesticides, June 29, 2021) Maine Governor Janet Mills (D) last week vetoed legislation prohibiting the aerial use of glyphosate and other dangerous herbicides in forestry practices. LD125, An Act To Prohibit the Aerial Spraying of Glyphosate and Other Synthetic Herbicides for the Purpose of Silviculture, was supported by a wide range of health and conservation groups, and aimed to bring the state in line with best practices for public health and the environment. With Maine recently passing one of the strongest consumer bans on pollinator-toxic neonicotinoids, advocates are dismayed by the setback from the Governor’s office. In a statement to Maine Public Radio, Senate President Troy Jackson said that Governor Mills should stop referring to herself as an environmentalist. “The science across the country, across the world, says that this stuff kills people, kills wildlife,” Mr. Jackson says. “And all that it is, is a giveaway to the large landowners so they can maximize their profits off the lives of the people in Maine and the wildlife in Maine.” Senator Jackson’s words are stern yet factual. Glyphosate has been identified by the World Health Organization as a probable human carcinogen. Monsanto, now owned by Bayer, has been the subject […]

(Beyond Pesticides, June 24, 2021) This Pollinator Week 2021, U.S. Representatives Earl Blumenauer (D-OR) and Jim McGovern (D-MA) are reintroducing the Saving America’s Pollinators Act (SAPA) in an effort to reverse ongoing declines in wild and managed pollinators.

Blumenauer. “We must use every tool at our disposal to provide pollinators with much-needed relief from bee-toxic pesticides and monitor their populations to ensure their health and survival.”  Neonicotinoids are systemic pesticides; once applied to a seed or sprayed on a plant they make their way into the pollen, nectar and dew droplets that plants produce and pollinators feed upon. Exposure impairs pollinator navigation, foraging, and learning behavior, and also suppresses their […]

(Beyond Pesticides, June 22, 2021) Glyphosate herbicide use in forested areas persists in the environment for years and can prompt morphological changes in perennial flowers that reduce their fertility and may make them less attractive to pollinators. These findings were published this month in the journal Frontiers in Plant Science by researchers at the University of British Columbia, who hope that their work will inform safer approaches to forest management. “The more we learn the better, and research can always be used to better inform management,” said lead author Lisa Wood, PhD. “Herbicide practices may change, if the research shows that this is in the public’s best interest.” Glyphosate herbicides like Roundup and Visionmax (a Canada-registered glyphosate product produced by Bayer/Monsanto) are often applied aerially via helicopter on wide swaths of forest land known as cutblocks. Cutblocks, designated areas where coniferous trees are grown for harvest and processing, are doused with glyphosate in order to manage understory trees and shrubs that would compete with the conifers. Researchers set out to understand the nontarget impacts of this practice on the surrounding forest ecosystem. Wild prickly rose (Rosa acicularis) plants were collected from three different cutblocks, each sprayed with Visionmax according to […]
