(Beyond Pesticides, August 25, 2021) Scientists at Oregon State University have found a highly effective bait for slugs and snails: bread dough. Although not quite as exciting as the slug-liquefying nematodes the OSU research team published data on last year, bread dough has the potential to revamp mollusk management, particularly in developing countries where resources are limited. “Bread dough is a nontoxic, generic, and effective tool that could be used in the detection and management of gastropods worldwide,” said study lead author Rory Mc Donnell, PhD. “It represents a tool to aid in managing pest gastropod infestations, either using baited traps or in attract-and-kill approaches. It could also be incorporated into existing baits to improve their attractiveness.” Critically, bread dough was found to be a more effective bait than commercial attractants like the product Deadline® M-Ps™, which contains the hazardous compound metaldehyde. To test effectiveness, researchers began by making the bread dough using a combination of flour, water and yeast. In a lab setting, slugs were starved for 24 hrs, and then given the option of either bread dough or water (water was used as a control to test if the slugs were simply attracted to humidity). Researchers determined through […]

(Beyond Pesticides, August 24, 2021) Organic agriculture provides multiple ecosystem functions and services at greater economic benefit to farmers than conventional, chemical-intensive cropping systems, according to research recently published in the journal Science Advances. The study, conducted by a team of scientists based in Switzerland, goes beyond farming evaluations based solely on ecosystem services to include socioeconomic elements. “We did this because agroecosystems also have a socioeconomic dimension for producers and policy makers,” the authors note. While it is unsurprising based on prior research that organic practices provide greater environmental and economic benefits, the study lays bare the true cost of policies that myopically focus on yield while ignoring other factors. Researchers conducted their study using data derived from a long-running Farming System and Tillage Experiment (FAST) based in Switzerland. FAST tracked four types of cropping systems: conventional intensive tillage, conventional no tillage, organic intensive tillage, and organic reduced tillage. Cropping systems were evaluated based on four broad categories, including provisioning (ie food production), regulating (ie water, air, and soil management), and supporting (ie biodiversity and soil health) ecosystem services, as well as socioeconomic well-being. These categories were subsequently broken down into nine assessments: soil health preservation, erosion control, biodiversity […]

(Beyond Pesticides, August 23, 2021) “Biopesticides”—widely regarded as an alternative to chemical pesticides and hence given a special status in regulation—need a better definition. “Biopesticide” is generally poorly understood, and defined differently by various entities and stakeholders. The term can be misleading and mixes contradictory approaches. It is 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 concerns among chemical-intensive farmers that they are losing pesticides in their arsenal, either to organism resistance or regulatory restrictions. The U.S. Environmental Protection Agency (EPA) uses the following definition for “biopesticides”: Substances that interfere with mating, such as insect sex pheromones, as well as various scented plant extracts that attract insect pests to traps (and synthetic analogs of such biochemicals); Microbial pesticides consisting of a microorganism (e.g., a bacterium, fungus, virus or protozoan) as the active ingredient; Plant-Incorporated-Protectants (PIPs), pesticidal substances that plants are genetically engineered to produce. Tell EPA it’s time to redefine “biopesticide.” It is deceptive and misleading. The definition should not include genetically modified organisms or synthetic analogs of naturally occurring […]

(Beyond Pesticides, August 20, 2021) The Office of the Inspector General (OIG) for the U.S. Environmental Protection Agency (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). The report’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.” This OIG report identifies and details the failings that Beyond Pesticides covered in an April 2021 Daily News Blog article, and many more — the net of which is that “we have yet to see EPA use endocrine disruption findings in pesticide registration decisions.” The OIG report chronicles a litany of failures. It finds that EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP), which is responsible for testing all pesticide chemicals for endocrine disrupting activity in humans, has failed to do so. Specifically, it has not implemented a section of the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the 1996 Food Quality Protection Act — the legislation that […]

(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 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 12, 2021) A recent study published in Chemosphere identifies the concentration, consequences, and potential sources of 22 organochlorine pesticides (OCPs) among corals in the South China Sea (SCS) for the first time. SCS corals exhibit a higher affinity toward bioaccumulation of OCPs, which are legacy persistent organic pollutants (POPs) under the Stockholm Convention—a global treaty to eliminate POPs. The study finds the distribution of OCPs in coral tissue matches that of the surrounding oceanic air samples. Hence, atmospheric concentrations of OCPs—influenced by continental air masses—migrate from the atmosphere to seawater through gas exchange. Coral reefs are one of the largest ecosystems in the ocean, sustaining marine biodiversity and providing many goods and services. However, living coral populations are rapidly declining due to ocean acidification, oceanic warming, habitat destruction, and pollution from human activity across the globe. From rare corals off the coast of Florida to well-established hard corals in the Great Barrier Reef, these communal organisms are sensitive to various environmental stressors that threaten biodiversity. Although several studies demonstrate the volatile, toxic nature of POPs, much less research evaluates the impact POPs have on biodiversity over time. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one million species of plants and […]

(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 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 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, 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, August 3, 2021) Research published this summer in the journal iScience outlines a promising, pesticide-free approach to manage non-native fire ants that have invaded many coastal communities along the eastern United States. As unabated climate change rapidly warms the planet, shifting wildlife habitat, and increasing the rate of intense storms and other natural disasters, pest insects like the fire ant are finding favorable conditions for their expansion into new areas. With pressure growing on land managers to resort to highly toxic pesticides to manage stinging and biting pests, it is increasingly important to invest in and emphasize new biological-based approaches. Scientists from the University of Maine focused in on a strain of fire ants known as Myrmica rubra, native to Europe and Asia and commonly known as the European fire ant. The ant is highly aggressive, attacking humans or other animals when disturbed, and boasts a powerful sting. In Europe, the ant plays an ecological role in conserving an endangered species of Maculinea sp. butterflies. The butterfly larvae send out chemical signals that mimic a queen ant, and the fire ants take the larvae into their nest. There, the larvae are protected from predators, and often are provisioned […]

(Beyond Pesticides, August 2, 2021) One reason to eat organic food is to join with a crucial national and global campaign to eliminate toxic, petroleum-based pesticides and fertilizers and protect ecosystems in the urgent fight to curtail the climate crisis and biodiversity decline—in addition to local and immediate health and environmental benefits. Despite an important and timely vote by the National Organic Standards Board (NOSB) in 2018 to protect native ecosystems as a critical tool in sequestering carbon and improving environmental resiliency, and despite the Biden Adminstration’s stated commitment to fighting the climate crisis, the U.S. Department of Agriculture and its National Organic Program (NOP) have not acted to put this recommendation in force. As our understanding of the connection between protecting intact ecosystems and combating climate change has grown, the urgency to implement this recommendation cannot be overstated. We must act now! Sign the petition to tell the National Organic Program (NOP) to take action to finalize the National Organic Standards Board (NOSB) recommended rulemaking that will protect Native Ecosystems and thereby preserve the integrity of the organic seal, help reverse the biodiversity crisis, and reduce global climate change. Sign by September 20, 2021. The Organic Foods Production Act […]

(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 29, 2021) Between 340,000 and 900,000 premature deaths each year can be linked to air pollution caused by the release of volatile organic compounds, such as pesticides, paints, and cleaning agents, from anthropogenic sources. The findings, published in Atmospheric Chemistry and Physics, included an international team of over 50 scientists, lead by researchers at the University of Colorado, Boulder. “The older idea was that to reduce premature mortality, you should target coal-fired power plants or the transportation sector,” lead author of the study Benjamin Nault, PhD, said. “Yes, these are important, but we’re showing that if you’re not getting at the cleaning and painting products and other everyday chemicals, then you’re not getting at a major source.” While the connection between air pollution and direct sources of particulate matter in the atmosphere have a large body of supporting literature, there is little understanding of the impact caused by other chemical products that humans use. Those direct sources, such as exhaust fumes from cars and the smoke stacks from coal-fired power plants, are generally regulated by government agencies in the U.S. and in other countries. Even secondary sources of pollution – such as nitrous oxides caused when fumes […]

(Beyond Pesticides, July 27, 2021) Researchers at North Carolina State University have developed pesticide-free clothing able to prevent 100% of mosquito bites for the wearer, and published proof of the garment’s effectiveness in a study in the journal Insects. If able to be scaled at a commercial level, the fabrics have the potential to transform personal protective measures for mosquitoes, which often includes in well-meaning consumers spraying toxic pesticides like DEET and permethrin on their body and clothing. “The fabric is proven to work – that’s the great thing we discovered,” said study co-author Andre West, associate professor of fashion and textile design at NC State and director of Zeis Textiles Extension for Economic Development in a press release. “To me, that’s revolutionary. We found we can prevent the mosquito from pushing through the fabric, while others were thick enough to prevent it from reaching the skin.” To create the mosquito-proof fabric, scientists turned to physics and mathematical models, rather than looking for new killer chemistries. “Our premise here is: why do we need an insecticide-treated textile when you can do it, now that you know a mathematical formula, without chemistry?” said Michael Roe, PhD, an N.C. State professor of entomology […]

(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 21, 2021) Western states are in the midst of one of the largest spray campaigns in recent history, targeting native grasshopper species on more than two million acres of rangeland with highly toxic insecticides. Grasshopper populations have exploded this year due to the West’s ongoing drought, and government officials at the U.S. Department of Agriculture are hoping that hazardous pesticide use will stop the voracious winged insects from consuming forage used by cattle operations. Environmental groups are urging changes to the program, which has conducted insecticide campaigns against the native grasshoppers since the 1930s. “Aerial application of insecticides on this scale will eliminate millions of insects that pollinate, recycle plant nutrients and perform natural pest control,” said Sharon Selvaggio, Pesticide Program Specialist with the Xerces Society. “Insecticide sprays on this scale across native ecosystems are short-sighted and unsustainable.” According to a June 2020 press release, USDA’s Animal and Plant Health Inspection Service (APHIS) is spending $5.3 million dollars of taxpayer money in order to conduct what it calls “suppression treatments.” APHIS claims the $5.3 million will protect $8.7 million worth of agricultural resources, but advocates argue that the agency has failed to meet the “level of economic […]
