(Beyond Pesticides, June 3, 2022) It is hardly news that plastics are a huge environmental problem, but three features of the plastic saturation of our planet are not well or widely recognized. One is the exacerbation of the climate emergency via emissions from the feedstocks for, and production and use of, plastics. Another is that proffered in a late 2021 report by the Food and Agriculture Organization of the United Nations: âthe land we use to grow our food is contaminated with even larger quantities of plastic pollutantsâ than the well-publicized amount of plastics in our oceans. The third is the little-known issue of the plastic coating of some synthetic pesticides and fertilizers, as investigated by a recent report from the Center for International Environmental Law (CIEL). Beyond Pesticides has written about the âcontributionsâ of plastics to the climate crisis, as well as issues related to uses of plastics in organic agriculture and the scourge of chemically intensive farming. An enormous amount of plastic in thousands of forms is produced globally each year. Toxic plastic pollution is now found, as The Guardian puts it, âfrom the summit of Mount Everest to the deepest oceans.â A frequently cited and chilling metric is this: the total mass of plastics […]

(Beyond Pesticides, June 1, 2022) A new evolutionary strategy spreading among German cockroaches is making them more difficult to kill than ever before. In a recent publication in Nature Communications Biology, scientists determined that cockroaches are developing an aversion to sugar baits containing glucose, with impacts that are changing their behavior and altering their mating rituals. âWe are constantly in an evolutionary battle with cockroaches,â said study co-author Coby Schal, PhD, of North Carolina State University. âEvolution can be sped up tremendously in the urban, human environment because the selection force imposed on insects, especially inside homes, is so intense.â At issue with German cockroaches is a trade-off between natural and sexual selection. Natural selection or, in this case, human-induced natural selection, has led cockroach females to become averse to baits containing glucose sugars. While many are now familiar with the fact that the vast majority of German cockroaches are resistant to nearly every synthetic pesticide, with some resistant to upwards of 10x the label application rate, less reported is the pestsâ growing resistance to sugar-laced baits. Sugar-containing baits have been employed for decades and, over time, cockroaches that are able to survive in locations where sugar baits were employed […]

(Beyond Pesticides, May 31, 2022) Fifty years after the banning of DDT, the notorious insecticide is still harming iconic birds of prey along the California coastline. According to research published in Environmental Science and Technology, California condors and marine mammals along Californiaâs coast are contaminated with several dozen different halogenated organic compounds (hazardous, often-chlorinated chemicals) related to DDT, chlordane, and other now-banned legacy chemicals. The findings highlight the incredible importance of addressing these original âforever chemicals,â and making certain that we do not continue to repeat the mistakes of the past with new and different, yet equally dangerous, chemistries. Between 1947 and 1971, the Montrose Chemical Corporation of California, the largest historical producer of DDT, released over 1,700 tons of DDT into the LA sewer system, which eventually made its way into the Pacific Ocean. During this time, several other companies discharged PCBs, leading to further chemical contamination of land and sediment. As recent as April 2021, scientists discovered 25,000 barrels likely containing DDT near Catalina Island along the southern California coast. These releases have resulted in serious environmental and health problems throughout the coastal food chain. Yet, as the present study shows, scientists are only beginning to understand the […]

(Beyond Pesticides, May 30, 2022) This Memorial Day, ask the U.S. government to show respect for veterans by recognizing Gulf War Illness (GWI) and honoring our commitment to those who have served the country. New research is providing strong causal evidence that Gulf War Illness (GWI) is the result of exposure to sarin gas, an organophosphate nerve agent, when Iraqi chemical weapons storage and production facilities were bombed during the Gulf War. The findings, published earlier this month in Environmental Health Perspectives, have important implications for the hundreds of thousands of American service members suffering from a constellation of chronic symptoms without a true understanding of how they became sick. âQuite simply, our findings prove that Gulf War illness was caused by sarin, which was released when we bombed Iraqi chemical weapons storage and production facilities,â said Robert Haley, MD, lead author of the study and epidemiologist at University of Texas Southwestern. âThere are still more than 100,000 Gulf War veterans who are not getting help for this illness and our hope is that these findings will accelerate the search for better treatment.â Tell the Secretary of Veterans Affairs and the U.S. Senate to provide disability benefits to those veterans […]

(Beyond Pesticides, May 27, 2022) In a U.S. Environmental Protection Agency (EPA) court document filed on May 16, the agency signaled potential changes to the labeling it requires for âover the topâ (OTT, or post-emergent) herbicides containing dicamba, a very problematic pesticide. The filing â in U.S. District Court for the District of Arizona, where EPA currently faces litigation about its 2020 dicamba registrations â comes as a result of Bayer, Inc.âs March 2022 proposed amendments to EPA registration for its XtendiMax herbicide, which contains dicamba and glyphosate. Beyond Pesticides has covered the dicamba saga for years, including the EPA Office of the Inspector Generalâs critical 2021 report citing an abandonment of science and assault on agency integrity for EPAâs dicamba decisions during the Trump years. Dicamba has been linked to cancer, reproductive effects, neurotoxicity, birth defects, and kidney and liver damage. It is toxic to birds, fish, and other aquatic organisms, and is known to leach into waterways after application. Dicamba also causes serious damage to non-GE (genetically engineered), non-target plants, damaging habitat and food sources for various organisms, especially for birds and insects. According to Progressive Farmer, EPA is currently considering some dicamba use restrictions after Bayer submitted them to […]

(Beyond Pesticides, May 25, 2022) Earlier this month, the U.S. Department of Justice urged the Supreme Court to deny a request by Bayer to review a verdict that found the corporation liable for damages from the use of its Roundup (glyphosate) herbicides. Now, Bayer is using proxy organizations to place pressure on the Biden Administration and Justice Department to rescind its decision. Alongside a range of chemical industry umbrella groups, many of whichâlike Croplife AmericaâBayer is a member of, a letter was sent to President Biden expressing âgrave concernâ about the opinion filed by Solicitor General Elizabeth Prelogar. Among a range of baseless claims, the agrichemical industry is deflecting lower court findings on the hazards and cancer risk of their products with the claim that their toxic chemicals are needed to feed the world, as crops shipments from Ukraine have been halted during the ongoing war. “The agrichemical industry has long tried to sell the idea that their toxic pesticides are needed to feed the world, as if to suggest that their motives are altruistic when, in fact, they have shown a callous disregard for life and a sustainable future,” said Jay Feldman, executive director of Beyond Pesticides. ” We […]

(Beyond Pesticides, May 24, 2022) New research is providing strong causal evidence that Gulf War Illness (GWI) is the result of exposure to sarin gas, an organophosphate nerve agent used by Saddam Hussein as a chemical weapon during the Gulf War. The findings, published earlier this month in Environmental Health Perspectives, have important implications for the hundreds of thousands of American service members suffering from a constellation of chronic symptoms without a true understanding of how they became sick. âQuite simply, our findings prove that Gulf War illness was caused by sarin, which was released when we bombed Iraqi chemical weapons storage and production facilities,â said Robert Haley, MD, lead author of the study and epidemiologist at University of Texas Southwestern. âThere are still more than 100,000 Gulf War veterans who are not getting help for this illness and our hope is that these findings will accelerate the search for better treatment.â Sarin was first synthesized in the late 1930s by Nazi chemists working for IG Farben (a consortium that included Bayer) in an attempt to create stronger and more powerful insecticides. Sarin is a G-series organophosphate (named after the scientists that created them), characterized by high acute toxicity and […]

(Beyond Pesticides, May 23, 2022)  The climate change-induced increase in wildfire frequency and intensity has lent new urgency to efforts to manage so-called âinvasiveâ plants. Unfortunately, the herbicide-based approach favored by many is both counterproductive and hazardous. It must be replaced by an organic system, incorporating biological control agents like goats and establishing a more resilient ecology.  Tell your county/city officials to replace herbicides with organic vegetation management. Tell EPA and Congress that herbicides must be evaluated in the context of the availability of organic systems. Use of the herbicide indaziflam is an example of the ineffectiveness of management based on herbicides. While indaziflam is considered a âselectiveâ herbicide, it actually kills and prevents germination of a wide range of broad-leaved plants and grasses and comes close to being a soil sterilant. The action on seedlings is long-lasting, thus inhibiting the growth and establishment of a resilient plant community that is resistant to invasion. Given its persistence and nonselective action and the extent of the damage it causes to native soil seed banks and plant biodiversity, indaziflam could contribute to the eventual ecological collapse of ecosystems where itâs applied, similar to the cascading impacts of the systemic insecticides, fipronil and […]

(Beyond Pesticides, May 20, 2022)Â Beyond Pesticides has long covered the various ways in which corruption related to pesticides, agriculture, and food â whether in industry or government â can result in harm to human and environmental health, including to a multiplicity of organisms, and their ecosystems and habitats. In this Daily News Blog entry, we will review the landscape of U.S. pesticide regulation, examples of corruption, and what can be done to counter it. A look at some recent instances provides unfortunate assurance that problems of corruption at EPA persist. A serious flaw in EPAâs registration (and periodic pesticide registration review) processes is their reliance on industry-provided data and research on safety of pesticide products, which does not reliably represent actual risks of harms. Agrochemical companies sometimes purchase research that yields biased or distorted findings, cherry pick results in their submissions to EPA, or try to suppress research findings. USRTK recently covered an instance in which Bayer (and other companies) funded a study on the impacts â of use of their neonicotinoid (neonic) corn seed treatments â on bees during planting season. Neonics have been widely implicated in the plummeting health, function, and populations of pollinators and in the so-called […]

(Beyond Pesticides, May 18, 2022) Bat population declines are costing American farmers as much as $495 million each year, finds research published this month in the Journal of the Association of Environmental and Resource Economists. Since 2006, a devastating fungal pathogen known as  Pseudogymnoascus destructans has torn through U.S. bat populations, causing a disease known as White Nose Syndrome that has killed over 90% of northern long eared, little brown, and tricolored bats. As researchers try to get a handle on the devastating and rapidly spreading disease, the effects are becoming apparent in agriculture as farmers lose their critical ecosystem services. “Lost bat populations have harmful ripple effects on food and agriculture,” says study coauthor Amy Ando, PhD. “Crop yields fall and input costs rise as farmers try to compensate for the services bats usually provide. That drives down the value of farmland and the number of acres planted, and the supply shock probably also hurts consumers as ag production becomes more costly.” White nose syndrome and its fungal pathogen were first discovered in a cave in New York in the mid-2000s, having likely traveled from Europe on the gear of a hiker or spelunker. The syndrome is characterized by […]

(Beyond Pesticides, May 17, 2022) With public awareness of an ongoing âinsect apocalypseâ growing, one of the first anecdotes people often note is how many fewer bugs are found splatted onto their car windshield than in the past. In a recent survey, conservation groups in Britain are finding evidence of insect declines in exactly that place, providing scientific backing for these concerning suspicions. Between 2004 and 2021, 58.5% fewer flying insects were squashed onto car license plates. âThe results from the Bugs Matter study should shock and concern us all,â says Paul Hadaway, conservation director at Kent Wildlife Trust, which conducted the study alongside UK organization Buglife. âWe are seeing declines in insects which reflect the enormous threats and loss of wildlife more broadly across the Country. These declines are happening at an alarming rate and without concerted action to address them we face a stark future. Insects and pollinators are fundamental to the health of our environment and rural economies.â The survey was conducted primarily through citizen science, utilizing the âBugs Matterâ mobile app, and a sampling grid, referred to as a âsplatometerâ that is affixed to a carâs license plate. Data was retrieved from trips taken by citizen […]

(Beyond Pesticides, May 16, 2021) Despite the fact that many more people die from living and working in unhealthy environments than from homicides or traffic crashes, resources put into preventing those deaths have been lackingâeven decreasing in recent years. Tell Congress to double budgets for environmental law enforcement. Toxic pesticide residues readily contaminate soils, water (solid and liquid), and the surrounding air at levels exceeding U.S. Environmental Protection Agency (EPA) set standards. Scientific literature demonstrates pesticidesâ long history of adverse effects on the environment, including wildlife, biodiversity, and human health. Pesticides can present acute and long-term health impacts worldwide, especially to farmers, 44 percent of whom experience pesticide poisoning every year. Furthermore, a 2020 study attributes approximately 385 million cases of non-fatal unintentional poisonings and 11,000 deaths annually to pesticides. The risks to human and environmental health must be met with strong environmental law enforcement. In the case of pesticides, this involves not only enforcement of label restrictions in the field, but also closer attention to ensuring that pesticides are not registered for uses in which risks outweigh benefitsâas required by law. The commitment to stronger environmental law enforcement should begin with a doubling of the budget for these activities. […]

(Beyond Pesticides, May 13, 2022)Â The Midwest Center for Investigative Reporting has covered a report, released days ago by the U.S. Environmental Protection Agency (EPA), that acknowledges the agencyâs failures to meet its responsibilities under the Endangered Species Act (ESA) and sets out a plan for improving its performance and meeting its obligations. The report, Balancing Wildlife Protection and Responsible Pesticide Use: How EPAâs Pesticide Program Will Meet Its Endangered Species Act Obligations, 2022, notes that these failures have resulted ânot only in inadequate protections for listed species, but also, litigation against the Agency that has increased in frequency in recent yearsâ â to the tune of more than 20 lawsuits covering 1,000+ pesticide products. Beyond Pesticides has covered the many chemical assaults on ESA species, as well as a number of lawsuits brought on their behalf â most recently, the Center for Biological Diversityâs (CBDâs) suit about the threats of synthetic pyrethroid insecticides to fragile species. Beyond Pesticides reported on a 2019 CBD lawsuit seeking to force the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (FWS) to initiate rulemaking to prevent most pesticide use in critical habitat for endangered species â an aspect of the […]

(Beyond Pesticides, May 11, 2022) Pregnant women are being exposed to increasing amounts of dangerous industrial chemicals, according to research published this week in Environmental Science and Technology. Â The chemicals in question include pesticides, plastics, and parabens, as well as âreplacement chemicalsâ for substances like phthalates and bisphenols that have gained notoriety for risks to public health. With a range of scientific data highlighting chemical exposures during pregnancy as a critical window of vulnerability, public awareness of these growing threats, and meaningful action by government regulators to reduce exposure is needed. Â The results of this study follow the release of data last year finding over 100 different chemicals in U.S. pregnant womenâs blood and umbilical cord samples. For the present study, however, researchers did not merely detect these chemicals, they tracked exposure levels over the course of 12 years. The cohort of 171 women represents a diverse group from seven American states and territories (including New Hampshire, New York, Puerto Rico, Illinois, California, and Georgia), with 20% of women participating Black, one third white, 40% Latina, and the remaining from other or multiple groups. Over the course of the study, routine monitoring was conducted utilizing an advanced diagnostic method […]

(Beyond Pesticides, May 10, 2022) Widespread weed resistance on chemical corn and soybean farms is leading farmers to till their fields more often, significantly increasing greenhouse gas (GHG) emissions. These findings were published late last month in the journal Nature Food by a team of Iowa State University researchers. With agricultural practices accounting for roughly 10% of U.S. GHG emissions, and 25% of worldwide releases, farming practices that preserve soil health and sequester GHGs are essential for the future of food production. Tillage is a farming practice that can provide a range of benefits for crop production, but only in the right conditions. A range of tillage practices exist, ranging from yearly conventional tillage, where most crop residue is plowed into the soil, to conservation tillage where some residue remains, and no-till systems where the soil remains covered. Repeated tillage causes significant harm to soil structure and biology, and result in erosion and the release of GHGs like carbon dioxide, methane, and nitrous oxide from soil into the atmosphere. The harms of tillage have led both chemical and organic farmers toward no-till or reduced tillage systems. Organic no-till farming, as practiced by farming groups like the Rodale Institute, employs the […]

(Beyond Pesticides, May 9, 2022) While the U.S. Environmental Protection Agency (EPA) updated its guidelines for pollinator risk assessments in 2014, the agency continues to either fail to conduct full assessments, or dismiss concerning data it receives. EPA appears to discount threats like the insect apocalypse, evidenced by a 75% decline in insect abundance, which threatens not only global ecosystems, but also food production that depends on animal pollination. As pesticides move through the food web, birds are also at risk. Bird numbers are down 29% since Rachel Carson wrote Silent Spring in 1962. Tell EPA To Protect Against Other Threats to Pollinators. Tell Congress To Insist that EPA Does Its Job. The problem is highlighted by EPAâs recent Interim Decision on fenbuconazole, in which the agency notes that, âFor larval bees, RQs (risk quotients) exceed the LOC (level of concern) for all pollinator attractive uses including when assessed at the lowest application rate of 0.0938 lb a.i./Acre (RQ = 1.1).â Yet in the same document, the agency declares that ââŚthe benefits of fenbuconazole (e.g., efficacy in management of fungal pathogens) outweigh any remaining risk and that continuing to register fenbuconazole provides significant benefits, including its ability to increase crop […]

(Beyond Pesticides, May 6, 2022)Â A December 2021 report commissioned by the trade group Salmon Scotland concludes that the use of pesticide products by the nationâs salmon farms represents potential risk to âwildâ swimmers (those who swim in open ocean waters). The reportâs primary finding is that the use of insecticide products containing azamethiphos (an organophosphate), deltamethrin, and hydrogen peroxide to control sea lice in farmed fish contaminates sea water and, thus, threatens swimmers in the areas around the farms. Beyond Pesticides has reported on pesticide use in aquaculture, and most recently, on developing resistance â in the parasitic lice (Lepeophtheirus salmonis) that endanger both wild and farmed fish populations in the North Atlantic â to some of the chemical treatments used by aquaculturists to combat the parasite. The intense exploitation of wild fish and other marine creatures for human food (and as an ingredient in animal feeds) has caused, in recent decades, depletion of fish and seafood stocks across the world. The aquaculture industry â in which various aquatic species (fish, shellfish, and some plants) are bred, raised, and harvested in the open ocean â has grown rapidly as a response. Since the 1960s, the farming of salmon in the […]

(Beyond Pesticides, May 4, 2022) Agricultural intensification and climate change are driving unprecedented losses in insect abundance and biodiversity, placing key ecosystem functions like food production in peril. The findings of this research, published in Nature by scientists at University College London, UK, are the first to elucidate the interactions between major drivers of the ongoing insect apocalypse. As civilization moves deeper into a time in which the impacts of a rapidly warming planet meet the devastating effects of habitat loss and rampant chemical use, it becomes ever more critical that action be taken now to avert the worst outcomes for the future of life on the planet. While the solutions are in reach, tremendous public action is needed to stop the fossil fuel and agrichemical industries from their short-sighted pursuit of profit at any cost, climate advocates say. To conduct their analysis, scientists utilized both short-term studies and the Projecting Responses of Ecological Diversity in Changing Terrestrial Systems (PREDICTS) database, which contains insect biodiversity sampling comprising twenty years of information (1992 to 2012). Species richness and total abundance were reviewed for nearly 20,000 insect species, including dragonflies/damselflies, moths and butterflies, flies, true bugs, beetles, bees and wasps, and grasshoppers/crickets […]

(Beyond Pesticides, May 3, 2022) Exposure to a commonly used fungicide considered to be âslightly toxic or nontoxicâ to pollinators makes male mason bees less likely to find a mate, jeopardizing future generations of critically important pollinators. This determination comes from research recently published in the Journal of Applied Ecology by scientists at Germanyâs University of WĂźrzburg. The timing of these findings comes after the U.S. Environmental Protection Agency (EPA) reapproved uses of fenbuconazole, the fungicide in question, late last year without completing all required studies on pollinator health effects. Horned mason bees (Osmia cornuta), a solitary bee species, have a complex mating process that includes a range of âpre-copulatory behaviorsâ used by male bees attract females. Males create thoracic vibrations with their flight muscles, rub the eyes of female bees with their antennae, and emit a distinct odor from their body. If the female likes the presentation, she will mate with the male. Otherwise, she will move him to the side and wait for another male to try to win her affection. To see how this process was influenced by pesticide exposure, researchers conducted a range of different experiments. For the first, newly emerged male and female bees were […]

(Beyond Pesticides, May 2, 2022) Lawns occupy 40 million acres, or 2% of the land in the U.S. Their maintenance typically involves pesticides and fertilizers that kill pollinators and soil life and wash into streams, where they do more damage. Lawn maintenance also involves a lot of mowing. While mowing is an effective way to encourage grasses over most broadleaved plants, it also has broader ecological impacts. The 3,600 species of bees in the U.S. and Canada range from large bumblebees to tiny sweat bees. There are many things you can do in your yard and community to protect these beesâstarting with managing lawns and landscapes organically and planting flowers favored by bees and other pollinators. This oneâNo Mow Mayârequires less work. Participate in No Mow May. Manage your landscape organically. Plant flowers for pollinators. Send a message to your mayor. No Mow May began with research by Plantlife in the UK and was taken up by property owners in Appleton, WI, who demonstrated that âhomes that participated in No Mow May had more diverse and abundant flora than regularly mowed green spaces throughout the city.â May is the month when many bees emerge from hibernation throughout the U.S. and […]

(Beyond Pesticides, April 29, 2022) The U.S. Fish and Wildlife Serviceâs (FWSâs) plan to list a rare milkweed species, and the areas in which it grows in south Texas, as critical and endangered has garnered political pushback from Texas Attorney General Ken Paxton. In February, FWS announced its intention to list 691 acres of prostrate milkweed habitat in order to protect it, given its critical role in supporting monarch butterfly populations. But Attorney General (AG) Paxton sent a letter to FWS saying that the critical and endangered determination âwould further destabilize Texasâs border, hindering the construction of the border wall,â and that it would risk security on the border with Mexico. FWS countered with a press release stating that, âThis listing and critical habitat proposal is based on the best available science, including a species status assessment that included input and review from academia and state agencies.â The 1973 Endangered Species Act (ESA) mandates that federal agencies, in consultation with FWS and/or the U.S. National Oceanic and Atmospheric Administration (NOAA) Fisheries Service, ensure that any actions in which they engage (whether authorizing, implementing, or funding) are unlikely to jeopardize the existence of a listed species, or have negative impacts on […]

(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 fungicidesâazoxystrobin, boscalid, cyflufenamid, fluopyram, tebuconazole, pyrimethanil, and trifloxystrobinâand two herbicidesânapropamide 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 […]

(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. âThe bottom line is that toxic pesticide use is not the answer to tick bites or tick-borne disease,â said Beyond Pesticides executive director Jay Feldman. âTo manage ticks, we must embrace ecological solutions that work with natural processes and education campaigns emphasizing personal protection.â Researchers set out to test two methods of broad area tick control in 24 residential neighborhoods in […]
