(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 â€slightly toxic or nontoxic’ 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 Germany’s University of WĂĽrzburg. 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 “pre-copulatory behaviors” 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, April 28, 2022) A study in Environmental Research finds that glyphosate’s primary metabolite (breakdown product), aminomethylphosphonic acid (AMPA), induces DNA damage through oxidative stress among subpopulations of primary school children. Although pyrethroid and chlorpyrifos metabolites can induce oxidative stress, this study is the first to investigate AMPA’s association with adverse health effects, rather than solely the effects of the active ingredient, glyphosate, in Roundup and other formulations. Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulations, readily contaminating soil, water, food, and other resources. Chemical use has been increasing since the inception of crops genetically modified to tolerate glyphosate. However, studies demonstrate glyphosate is among the most prevalent pesticide contributors to human, biotic, and ecosystem harm. According to research, herbicide toxicity to invertebrates has doubled since 2004. Although research links glyphosate exposure to cancer, specifically non-Hodgkin lymphoma, much less research considers the effects that metabolites have on children who are more vulnerable to chemical exposure. Ecological and health risk assessments primarily focus on active ingredients in pesticide products, overlooking the potential impacts of metabolites. Thus, studies like these highlight the need to assess the implications of metabolite exposure to protect human, animal, and environmental health. The study notes, “Our […]

(Beyond Pesticides, April 21, 2022) A literature review published in Royal Society finds that â€inert’ ingredients’ in pesticide formulations adversely affect the health of bees and other wild pollinators. Inert ingredients, also known as “other” ingredients, and not disclosed by name on pesticide product labels, facilitate the action of active ingredients targeting a specific pest. Although both ingredients have chemical and biological activity, most studies on agricultural chemical toxicity focus on the active ingredient, assuming that inert ingredients are “nontoxic.” The U.S. Environmental Protection Agency (EPA), in regulating pesticides, assesses the toxicity of individual active ingredients on bees through various testing methods. However, there are no requirements for EPA to test inert ingredients to the same degree, despite evidence demonstrating these chemicals harm pollinators. Moreover, EPA does not require pesticide manufacturers to disclose the inert ingredients used in any product as the information is confidential. Both wild and commercial bees and other pollinators encounter multiple stressors, including pesticides, parasites, and poor nutrition, that act together to increase the risk of bee mortality. Therefore, reviews like these highlight the need for pesticide testing to consider the effects of all product ingredients, regardless of perceived toxicity. The researchers caution, “We argue that â€inert’ ingredients […]

(Beyond Pesticides, April 20, 2022) A University of Michigan study is the first to highlight that maternal pesticide exposure during pregnancy adversely affects sleeping patterns for offspring later in life, specifically for females. Prenatal development is one of the most vulnerable periods of exposure as the fetus is most susceptible to the harmful effects of chemical contaminants. Many studies indicate that prenatal and early-life exposure to environmental toxicants increases susceptibility to diseases, from learning and developmental disabilities to cancer. However, the toxicity of pesticide exposure ad its full impact on the nonagricultural population in the U.S., especially women. Given research links to sleep-related disorders and neurological and cognitive development, studies like this can help government and health officials identify how pesticides’ impact on the brain elevates health concerns. The authors note, “Overall, these results are of public health importance considering the continued widespread agricultural and possibly residential use of pyrethroids and chlorpyrifos [in Mexico]…Thus, our results underline the importance of additional research studies that include both larger samples and assessment of unregulated pesticides, as well as studies that consider the underlying mechanisms explaining sex differences.” Levels of inadequate sleep patterns are rising among children and adolescents. Reports find variability in sleep duration results in higher rates of depression, anxiety, and […]

(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 […]

(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 […]

The organic solutions to problems highlighted in the latest issue of Pesticides and You—based on the importance of healthy ecosystems and public health protection—are within reach, and the data creates an imperative for action now that phases out pesticides within a decade, while ensuring food productivity, resilient land management, and safe food, air, and water. (Beyond Pesticides, April 15, 2022) The current issue of Pesticides and You, RETROSPECTIVE 2021: A Call to Urgent Action, is a look at a year of science, policy, and advocacy that informs both the existential problems that the U.S. and the world are facing due to toxic pesticide dependency, and solutions that can be adopted now. The information in this issue captures the body of science that empowers action at the local, state, and federal level, and provides a framework for challenging toxic pesticide use and putting alternatives in place. The issue finds that 2021 was a pivotal year in both defining the problem and advancing the solution. This year in review is divided into nine sections that provide an accounting of scientific findings documenting serious pesticide-induced health and environmental effects, disproportionate risk to people of color and those with preexisting conditions, regulatory failures, at the same time […]

(Beyond Pesticides, April 12, 2022) A recent study published in Scientific Reports warns that parasitic salmon lice (Lepeophtheirus salmonis) in Pacific Ocean open-net fish farming operations are becoming resistant to emamectin benzoate (EMB), an active ingredient used to control salmon lice population in North America, both in the U.S. and British Columbia, Canada. Previously, researchers believed parasitic salmon lice only had high rates of chemical resistance in the Atlantic region due to the mixing of farmed and wild salmon. However, Pacific salmon lice are exhibiting similar rates of decreased sensitivity to EMB from various sources, including a decrease in the wild Pacific salmon population, overuse of chemical treatments, and reliance on single chemical treatments. The aquaculture industry (e.g., farmed seafood/fish) repeatedly faces sustainability issues, failing to adhere to environmental regulations and threatening marine health. Extensive use of pesticides to rid the parasite has led to widespread resistance to multiple pesticides, prompting increasing infection rates among North Atlantic salmon populations. These parasites endanger both farmed salmon and wild salmon, in addition to other local species of fish. In this context, pesticide treatments contributes to resistance among lethal pest populations, especially in ecologically vulnerable and interconnected ecosystems like ocean basins. The researchers caution, “Salmon […]

(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 […]

(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, […]

(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 […]

(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 […]

(Beyond Pesticides, April 5, 2022) A meta-analysis by the Federal University of Technology – Paraná finds the herbicide 2,4-D causes indiscriminate harm, increasing the mortality rate among exposed animals. The severity of chemical exposure relies on species sensitivity, exposure rate, and lifecycle stage. However, commercial formulations of 2,4-D, commonly used in the environment, prompt a higher species mortality rate than technical (pure) 2,4-D alone. Like many other common herbicides such as glyphosate, 2,4-D has global uses that allow the chemical to accumulate in the environment, including soils, waterways, and tissues of non-target species. Therefore, meta-analyses like this help local and government officials make holistic decisions regarding environmental contaminants that incorporate conclusions from various studies. Using the Web of Science and Scopus databases, researchers compiled various studies (or meta-analyses) on the lethality of 2,4-D in different animal species (e.g., vertebrates, invertebrates). Researchers evaluated each study regarding the mortality rate of control and experimental groups, animal sensitivity to chemical exposure during a specific life stage, chemical formulation (e.g., commercial or technical), and exposure routes causing mortality. The analysis demonstrates that vertebrates experience higher mortality rates from 2,4-D exposure, with fish and birds presenting the highest mortality rate. Regarding life stages, larval and adult […]

(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 […]

(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 […]

(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 […]

(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 […]

(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 […]

(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 […]

(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 […]

(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, […]

(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 […]
