Pesticide Concentration through Metamorphosis Contaminates Birds and Bats

(Beyond Pesticides, April 27, 2022) Pesticides can accumulate in aquatic fly larvae, be retained through metamorphosis, and represent a source of chronic pesticide exposure to birds and bats, according to research published in Environmental Science and Technology earlier this month. As population declines among these critical wildlife continue to mount, findings like these highlight the complex ways in which human activities are further stressing natural systems. Pesticide reviews conducted by the U.S. Environmental Protection Agency (EPA) are limited to an outdated set of studies conducted by the pesticide industry, and generally reject and dismiss emerging science from independent literature. This myopic focus on industry studies has brought widespread contamination to the natural world that necessitates wholescale changes at EPA through Congressional action. With widespread acknowledgement that older pesticide chemistries, such as organochlorines like DDT and aldrin, bioconcentrate in living organisms, researchers aimed their study at present use fungicides and herbicides that have not yet undergone similar scrutiny. This includes seven fungicides—azoxystrobin, boscalid, cyflufenamid, fluopyram, tebuconazole, pyrimethanil, and trifloxystrobin—and two herbicides—napropamide and propyzamide. The study notes that formulated end use products, rather than technical grade active ingredients, were used in order to best mimic real world exposure conditions. Larvae of the […]

CDC Study: Pesticide Use Does Not Reduce Risk of Lyme, Other Tick-Borne Disease

(Beyond Pesticides, April 26, 2022) Using pesticides to reduce the number of ticks in residential areas does not translate to lower rates of tick-borne disease in humans. This finding is the culmination of research overseen by scientists at the U.S. Centers for Disease Control and Prevention (CDC), which have been studying the effectiveness of pesticides to manage tick bites and tick borne-diseases for over a decade. While earlier research focused on direct pesticide applications to individual household lawns, the most recent publication, under early release in the Journal of Emerging Infectious Diseases, represented a broader, neighborhood-wide implementation of control measures. Yet in both instances, pesticide use did not play a role in reducing tick-borne disease. The studies are a stark warning for states and communities considering vector disease spray campaign for ticks in a similar manner to mosquito spraying. “The bottom line is that toxic pesticide use is not the answer to tick bites or tick-borne disease,” said Beyond Pesticides executive director Jay Feldman. “To manage ticks, we must embrace ecological solutions that work with natural processes and education campaigns emphasizing personal protection.” Researchers set out to test two methods of broad area tick control in 24 residential neighborhoods in […]

Black, Indigenous, and People of Color Community at Disproportionate Risk from Pesticides, Study Finds

(Beyond Pesticides, April 22, 2022) A study published on April 18 finds that people in U.S. BIPOC (Black, Indigenous and People of Color) communities, as well as those living in low-income communities, endure a very disproportionate rate of exposure to pesticides, and of subsequent risks of harm. It finds that such disparities exist in both urban and rural communities, and at all points in the pesticide “life cycle,” from manufacture to application. A section of Beyond Pesticides’ recent mega-issue of Pesticides and You, “Retrospective 2021: A Call to Urgent Action,” is devoted to such inequities. Section IV, “Disproportionate Pesticide Harm Is Racial Injustice: Documenting Victimization: Structural Racism,” reprises Beyond Pesticides’ 2021 coverage of environmental injustices. It also calls for urgent action re: federal and state “evaluations that go into toxic chemical regulation . . . to reform and replace the current regulatory decision-making process, which is empirically racist, with one that acknowledges and cares for those with the highest real-world vulnerabilities and exposure[s].” The first comprehensive assessment of disparities in pesticide protections and oversight in the U.S., the study paper appeared in the journal BMC Public Health. The authors set out the broad history of how humanity moved from “Traditional Ecological […]

Maine Moves to Ban Pesticides and Fertilizers Contaminated with PFAS

(Beyond Pesticides, April 19, 2022) Both houses of Maine’s legislature have just approved a bill that would, by 2030, ban pesticides that contain PFAS chemicals — the so-called “forever chemicals.” The bill’s next stop is the Appropriations Committee, for approval of $200,000 in annual funding to enact the bill; if successful there, it will move to the desk of Maine Governor Janet Mills for her signature. The legislation is one of a suite of lawmaker efforts in the state to address the growing PFAS problem with which localities across the U.S. are struggling. In this Daily News Blog article, Beyond Pesticides continues its coverage of the scourge of PFAS chemicals, particularly as it relates to pesticide use and the use of fertilizers made from PFAS-contaminated “biosludge” from municipal treatment facilities. PFAS — “per- and poly-fluoroalkyl substances” — are any of a family of more than 9,000 synthetic chemicals, invented in, and widely deployed since, the 1950s in a multitude of industrial and consumer products. PFAS molecules are made up of a chain of linked carbon and fluorine atoms; the carbon–fluorine bond is one of the strongest chemical bonds that exists, which means that these compounds do not break down in the […]

USDA Must Take Steps To Prevent an Avian Flu Pandemic

(Beyond Pesticides, April 18, 2022) Industrial poultry operations—generally indoors and with crowded conditions—provide the perfect incubator for pandemic influenza. According to the United Nations Food and Agriculture Organization (FAO), “These involve the congregation of large numbers of genetically identical animals of the same age (young) and sex, with rapid turnover and â€all-in, all-out’ systems.” The U.S. Department of Agriculture (USDA) is delaying the adoption of organic rules that would require meaningful outdoor access and prevent indoor crowding. Influenza pandemics have killed millions of people—between 20 and 40 million people died in the 1918 pandemic, one million in 1957, and one to three million in 1968. According to the World Health Organization (WHO), “Influenza type A viruses are of most significance to public health due to their potential to cause an influenza pandemic.” There are several subtypes of type A influenza, which originates in birds. According to the Centers for Disease Control (CDC), there were 700 human cases of the H5N1 subtype since 2003, and only 40% survived. Tell USDA to promulgate a strong Organic Livestock and Poultry Standard. Tell USDA to protect against flu pandemics by applying the same rules to all poultry. Because avian flu poses a risk to […]

Winning the “War on Rats” Requires Community-Wide Systemic Change, Says New Study

(Beyond Pesticides, April 14, 2022) Over the last century, cities across the world have engaged in a “war on rats” that has failed to achieve meaningful results, and should consider a new paradigm for rodent management, according to a review of relevant literature published in Frontiers in Ecology and Evolution last month. As awareness regarding the widespread dangers of commonly used rodenticides increases, and states like California begin to rein in their use, the importance of alternative management approaches has grown. Reviewing over 100 studies on municipal rat management, the authors outline a path forward that embraces a systems approach and calls for a change in public expectations. Since the early 1900s, municipal rat management has primarily focused on killing rats and removing their food, water and harborage, but data available on the efficacy of this approach is sparse. Successful programs, according to the literature, are often grant funded and time limited, or employ such substantial amounts of rodenticide that it carries significant risks regarding secondary poisoning of people and nontarget species. Failures consistently note the ephemeral nature of rodent reductions. A 1909 study referenced in the review, from which the authors indicate much of present-day rodent management is based, […]

Ecosystem Services Provided by Birds and Bees Synergize to Increase Farm Yield and Profit

(Beyond Pesticides, April 13, 2022) The combined effects of insect pollination and natural pest control provided by birds synergize to improve yields and income for coffee farmers, finds research published this month in the journal PNAS. Ecosystem services – the positive benefits provided by ecosystems, wildlife, and their natural processes – underpin agricultural production, but are often analyzed in silos, on a case by case basis in the scientific literature. The current research finds that the quantitative benefits of ecosystem services can be greater when considering their interactive effects. “Until now, researchers have typically calculated the benefits of nature separately, and then simply added them up,” says lead author Alejandra MartĂ­nez-Salinas, PhD of Costa Rica’s Tropical Agricultural Research and Higher Education Center (CATIE). “But nature is an interacting system, full of important synergies and trade-offs. We show the ecological and economic importance of these interactions, in one of the first experiments at realistic scales in actual farms.”   Researchers based their experiment in Costa Rica, working with 30 shade grown coffee farms owned by small landholders. Eight coffee plants on each farm were selected for the study. Pest control services provided by birds were assessed using a 20mm mesh screen that excludes […]

International Aid Needed To Support Traditional and Organic, Not Chemical-Intensive, Agriculture

(Beyond Pesticides, April 11, 2022) As the U.S. encourages the spread of chemical-intensive, industrialized agriculture, local farmers are increasingly pressured into giving up traditional agricultural practices in favor of monocultures to increase the demand  for agrichemical pesticides and fertilizers worldwide. This policy is promoted by the industry with vested economic interests as good for the U.S. economy, but it is not good for either planetary health or global food security. Instead, U.S. foreign aid agencies, through the U.S. Agency for International Development (USAID) and other agencies, should be supporting traditional practices and organic agriculture. Tell Congress and U.S. AID to support aid that promotes traditional and organic agriculture.  Industrial agriculture depends on monoculture—growing single crops that can be easily planted, fertilized, treated with pesticides, and harvested—especially on large-scale, mechanized farms. In spite of the perceived advantages of monoculture, however, it is a significant contributor to biodiversity loss and pollinator decline. Loss of biodiversity feeds the pesticide treadmill by removing predators and parasites who keep crop-feeding insects below damaging levels. The vast majority of crop plants depend on pollinators. Traditional agriculture, like organic agriculture, depends on interacting species. Most organic agriculture resembles monoculture piecewise, but integrates cover crops, hedgerows and other […]

Broken Promises, Empty Pledges Leading to Irreversible Climate Disaster: UN Says It’s Now or Never

(Beyond Pesticides, April 8, 2022) “The jury has reached a verdict. And it is damning. This report of the Intergovernmental Panel on Climate Change is a litany of broken climate promises. It is a file of shame, cataloguing the empty pledges that put us firmly on track towards an unlivable world. We are on a fast track to climate disaster.” These words came from United Nations Secretary-General AntĂłnio Guterres in a statement responding to the latest IPCC (Intergovernmental Panel on Climate Change) report released on April 4. As a Beyond Pesticides Daily News Blog headline virtually shouted in October 2021, “Climate Crisis, Soil, Pesticides, Fertilizers: Red alert! This is Not a Drill!” This IPCC report — Climate Change 2022: Mitigation of Climate Change — is the third and final part of the panel’s latest review of climate science. It is informed by the work of thousands of scientists, and follows on the first two of the trio of reports that comprise the comprehensive Sixth Assessment Report. The first, Climate Change 2021: The Physical Science Basis, from the IPCC Working Group I, was released on August 9, 2021. The second, Climate Change 2022: Impacts, Adaptation, and Vulnerability, from Working Group II, […]

Industry, Money, and Politics Drive Legislation to Squelch Local Pesticide Restrictions

(Beyond Pesticides, April 7, 2022) Legislation introduced by U.S. Representative Rodney Davis (R-IL) last week would roll back, preempt, and prohibit local jurisdictions from enacting policies that protect resident health and a community’s unique local environments from hazardous pesticides. The bill, H.R.7266, is a direct attack on the scores of local communities that have enacted common sense safeguards from toxic pesticides, and represents the pesticide industry’s response to the growing momentum of the pesticide reform movement. Health and environmental advocates are expecting Rep. Davis and his partners in the agrichemical industry to attempt to work the provisions of the legislation into the upcoming 2023 farm bill. The industry had previously attempted to work federal preemption into the 2018 farm bill, an effort that ultimately failed after massive pushback from health advocates, local officials, and Congressional allies. Rep. Davis’ press release for the bill, in which he was joined with quotes from a range of agrichemical industry leaders, is titled “Davis Introduces Legislation to Prevent Liberal Local Governments from Banning or Restricting Pesticide Use,” striking a partisan tone. Caring about public and environmental health is typically not viewed as a liberal or conservative, Democratic or Republican issue. Those monitoring local governments […]

Conventional Apples Found to Be Coated in Fungicides and Drug-Resistant Fungi

(Beyond Pesticides, April 6, 2022) Conventional apples sold at market and sprayed with synthetic fungicides may not only contain drug-resistant fungi, but function as a transmission reservoir and route to spread these dangerous pathogens, finds research published in mBio late last month by a team of researchers from India and Canada. As reports of fungal resistance rise, particularly in hospitals and among the immunocompromised, there is an urgent need to understand and address the root causes of these emerging disease threats. “When we look at human pathogens, we tend to look at what’s immediate to us,” said study coauthor Jianping Xu, PhD. “But we have to look at it more broadly. Everything is connected, the whole system. Fruit is just 1 example.”   Researchers set out their research with the suspicion that stored fruits sprayed with synthetic fungicides were acting as a source and route of transmission for the deadly fungi Candida auris. This yeast is considered an “emerging fungal pathogen” by the U.S. Centers for Disease Control and Prevention (CDC), and has increased its rate of infection significantly since its initial identification in the mid 1990s. The fungi has been found in every continent save Antarctica. It has proven to […]

EPA Considers Future of Bee-Toxic Neonic Insecticides as Scientific Evidence Supports Ban

(Beyond Pesticides, April 4, 2022) Recent actions by the U.S. Environmental Protection Agency (EPA) highlight the urgent need to prevent pesticides from further endangering crucial pollinators, including birds, bees, and bats. Tell EPA To Ban Neonics and Protect Against Other Threats to Pollinators. Tell Congress To Insist that EPA Does Its Job. Despite EPA’s own findings of evidence of serious threats posed by neonicotinoid (neonic) pesticides to pollinators, aquatic invertebrates, and other wildlife, it issued interim decisions on these neonics in January 2020 that disregard the science on the pesticides’ impacts and it appears that the agency is prepared to finalize these registrations late in 2022. This would, barring further action, extend the use of these harmful compounds for 15 years. Now is the time to let EPA know that continued use of neonicotinoids is unacceptable. Furthermore, building on a history of unenforceable and impractical pesticide label restrictions resulting in EPA findings of ludicrously small or no risk, the agency spun its approval of the continued use of the deadly organophosphate insecticide malathion as “protecting threatened and endangered species.” As the nation and world sit on the brink of biodiversity collapse and deadly pesticide-induced diseases, EPA actions continue to protect pesticide […]

Coverup of Dog Deaths at EPA, According to Internal Emails on Seresto Flea and Tick Collars

(Beyond Pesticides, April 1, 2022) According to reporting by E&E’s Greenwire, internal emails at the U.S. Environmental Protection Agency (EPA) show that career scientists at the agency expressed worry about pesticide-laced pet collars, such as the notorious Seresto flea and tick collars, but that EPA managers “instructed them to avoid documenting those worries in publicly accessible records.” The emails were released pursuant to a 2021 FOIA (Freedom of Information Act) lawsuit, brought by the Center for Biological Diversity (CBD), that sought records of internal communications. The documents evidence staff concern about the collars that has not been a part of EPA’s public communications on the subject. EPA staff, in the emails, expressed a range of degrees of outrage at managers’ behavior and at the very registration of the product, given the significant harms. Seresto collars are plastic pet collars embedded with pesticides designed to kill fleas, ticks, and lice; they contain the active ingredients flumethrin and imidacloprid. Flumethrin, a chemical in the pyrethroid class of synthetic neurotoxic insecticides, has been linked repeatedly to neurological issues, such as seizures and learning disabilities in children, to gastrointestinal distress, and to damage to nontarget invertebrates, according to EPA’s own analysis. Imidacloprid is a commonly used pesticide linked to […]

Traditionally-Produced Compost Improves Soil, Outperforms Synthetic Chemical Fertilizers

(Beyond Pesticides, March 31, 2022) Composts produced using traditional ecological knowledge create healthier, more fertile soil than industrial, chemical-based fertilizers, according to the findings of a recent study published in PLOS Sustainability and Transformation. As the dangers posed by industrial agriculture become increasingly apparent, organic and traditional practices show a time-tested path toward a sustainable farming future. According to study author Seema Sharma, PhD, “The research was already there because the ancient people did their research long ago,” she said to EOS. “But when it comes to the scientific community, you need research that is in a peer-reviewed journal and then finally verified.” The study focuses its comparison within the Kachchh district, a semi-arid farming area of Western India that experiences erratic rainfall and has higher salt levels in its soils than much of the rest of the country. Twenty farms were chosen based on their fertilizer management practices, split between farmers employing traditional composting techniques and those using chemical fertilizers. For the chemical farms, an initial application of animal-based manure was applied, and synthetic sources of nitrogen (urea) and phosphorus (ammonium phosphate) were then spread as a top dressing at a rate of roughly 60kg (132lbs)/ha approximately 20 days […]

Producers Warned by EPA that PFAS Is Contaminating Pesticides and Food

(Beyond Pesticides, March 29, 2022) Plastic storage barrels contaminated with polyfluoroalkyl substances (PFAS) may be in violation of the Toxic Substances Control Act (TSCA), according to an open letter released by the U.S. Environmental Protection Agency (EPA) last month. Manufacturers, producers, processors, distributors, users, and those that dispose of fluorinated High-Density Polyethylene (HDPE) containers or other similar plastics that form PFAS as a byproduct were notified in the letter of requirements under federal law. The notice comes two years after EPA was first alerted to the presence of PFAS in a mosquito pesticide used by the state of Massachusetts known as Anvil 10+10. “Today’s action will help ensure that responsible parties are held accountable for any future PFAS contamination affecting communities,” said Assistant Administrator for the Office of Chemical Safety and Pollution Prevention Michal Freedhoff, PhD. While the agency believes its letter represents progress, health advocates note that there has been no meaningful regulatory action from the agency on this issue. In January 2021, a year after receiving notice from Public Employees for Environmental Responsibility (PEER) on the presence of PFAS on Anvil 10+10, EPA confirmed the finding. At the time the agency did nothing, while acknowledging, “the need to […]

Environmentalists Outraged at Probability that EPA Will Allow Continued Use of Deadly Pesticides, the Neonicotinoids

(Beyond Pesticides, March 25, 2022) Recent coverage by The Guardian of the U.S. Environmental Protection Agency’s (EPA’s) plan — to extend the registration of several demonstrably harmful neonicotinoid insecticides — compels Beyond Pesticides to identify, once again, the agency’s failures to enact its core mission. That mission is “to protect human health and the environment,” and to ensure that “national efforts to reduce environmental risks are based on the best available scientific information.” EPA has undertaken a review of the registration of several members of the neonicotinoid (neonic) family of pesticides and, despite the agency’s own findings of evidence of serious threats to pollinators, aquatic invertebrates, and other wildlife, it issued interim decisions on these neonics in January 2020 that disregard the science on the pesticides’ impacts. EPA appears to be prepared to finalize these registrations late in 2022; this would, barring further action, extend the use of these harmful compounds for 15 years. Neonics are used widely in the U.S., both on crops to kill sucking insects, and as seed treatments with the same goal for the developing plant. These insecticides are systemic compounds, meaning that once applied, they travel to all parts of a plant through the vascular […]

Certain Essential Oils Found To Be Highly Effective at Killing Mosquito Larvae and Adults

(Beyond Pesticides, March 24, 2022) A range of essential oils can provide high levels of larvicidal and adulticidal activity against a commonly found species of mosquito, according to research published last week in Scientific Reports. The use of essential oils in mosquito management has generally been limited to personal protection, with synthetic pesticides often the first choice for vector control activities. This research highlights the potential role of these natural compounds to replace hazardous synthetics in managing larval sources and killing adult mosquitoes under last-resort scenarios. The team of Egyptian-based scientists conducting the study purchased 32 different essential oils from a regional retailer in order to test them on both the larval and adult stages of Culex pipiens. C. pipiens, often referred to as the common house mosquito, is the most abundant mosquito in the Northern U.S., and is known to vector West Nile virus and Saint Louis encephalitis, among other diseases. Larval efficacy was tested on the fourth instar larvae of C. pipiens, delivered through a mixture of the essential oil, water, and the solvent Tween-20, which contains the surfactant Polysorbate-20, used to emulsify the mixture. All oils tested had some level of larvicidal activity (between 60-100%). Researchers classified […]

Cockroaches Exhibit Resistance to Pesticides at 10x Label Application Rates

(Beyond Pesticides, March 22, 2022) German cockroaches collected from U.S. residential homes have evolved resistance mechanisms so strong that many can consume ten times the pesticide required to kill a laboratory-susceptible strain and still not die. These are the findings of recent research published in the Journal of Economic Entomology, which focused on determining cockroach resistance levels to commonly used gel bait insecticides in infested Southern California homes. The findings underscore the importance of an integrated approach to cockroach management that recognizes and responds to pest ecology, rather than search for an ever-elusive silver bullet. Researchers collected five different strains of German cockroaches from various locations around Southern California, two from public housing and three from apartment dwellers. All sites had long-standing cockroach infestations, with varying treatment histories that generally included significant use of common gel bait insecticides. Tests were conducted on male cockroaches as they are gregarious foragers and thus more susceptible to baited food; it was indicated that if an insecticide cannot kill a male, it is highly unlikely to kill a juvenile or female roach. A separate group of cockroaches reared in the laboratory and never exposed to insecticides was used as a baseline for comparison. This […]

Government Inaction Threatens Endangered Species, Calls for Action

(Beyond Pesticides, March 21, 2022) With a history of unenforceable and impractical pesticide label restrictions resulting in U.S. Environmental Protection Agency (EPA) findings of ludicrously small or no risk, the agency is at it again with its latest announcement that spins its approval of the continued use of the deadly organophosphate insecticide malathion as “protecting threatened and endangered species.” This just the latest example of an irresponsible federal agency falling far short, as the nation and world sit on the brink of biodiversity collapse and deadly pesticide-induced diseases. Tell EPA to protect endangered species. Tell Congress to make sure the Biden administration protects endangered species.  The announcement follows the release of a final biological opinion by U.S. Fish and Wildlife Service (FWS), which, according to the Center for Biological Diversity (CBD), “relies on scientifically unfounded assessment methods imposed during the Trump administration [and] stands in sharp contrast to the agency’s 2017 conclusion that 1,284 species would likely be jeopardized by malathion.” Meanwhile, the National Marine Fisheries Service, a sister agency to the U.S. Fish and Wildlife Service, released an updated biological opinion that determined malathion and two other toxic organophosphate pesticides are causing jeopardy to virtually every endangered U.S. salmon, sturgeon, […]

Pesticide Drift or Chemical Trespass Continue Uncontrolled, Despite Successful Litigation

(Beyond Pesticides, March 18, 2022) A 2020 lawsuit related to pesticide drift was resolved on March 8, 2022 in San Joaquin (California) Superior Court with the finding that Alpine Helicopter Services, which specializes in pesticide applications for government and tourism entities, had violated pesticide drift laws and endangered public health and safety. The court further found Alpine liable for damage related to its actions, though penalties in the case, brought by California state prosecutors and the California Department of Pesticide Regulation (DPR), have yet to be determined. The case exposes a handful of the many instances of pesticide drift, also known as “chemical trespass,” that occur every year in the U.S. In 2004, Beyond Pesticides covered the issue with Getting the Drift on Chemical Trespass; its monitoring of drift issues is ongoing, as can be seen in its “Pesticide Drift” archives. The long history of nontarget exposure, contamination, and poisoning teaches that drift is a function of pesticide use, but not considered adequately by regulators who allow the marketing of poisons that are known to move through the environment uncontrolled. Cases like the Alpine case highlight a relentless problem associated with the daily use of pesticides. Pesticide drift is any airborne […]

(Beyond Pesticides, March 16, 2022) Pest damaged plants release volatile chemical “scents” that alert other nearby plants of potential predators and give them time to prepare their defenses, according to research recently published in Plant Physiology by researchers at Tokyo University of Science. The findings have important implications for agriculture, including new practices that utilize this novel process. “The effective use of plants’ natural survival strategies in production systems will bring us closer to the realization of a sustainable society that simultaneously solves environmental and food problems,” says study coauthor Gen-ichiro Arimura, PhD. Budding research conducted since the turn of the century has discovered and confirmed that plants can communicate through specific volatile organic compounds (VOCs).  These compounds, referred to by researchers as “infochemicals,” can act as airborne signals that an herbivore danger is in the vicinity. Not only can plants within the same species communicate, there is evidence that plants will react to infochemicals produced by different species the other plant cannot produce, and may never have encountered. A recent experiment found, for instance, that soybean plants grown near mint are better able to withstand pest pressure by “eavesdropping” on VOCs produced by mint. Likewise, corn and tomato plants […]
