(Beyond Pesticides, February 22, 2023) Combining neonicotinoid insecticides with other commonly used pesticides can result in synergistic effects on honey bees, increasing toxicity more than any individual chemical could, according to research published in Scientific Reports earlier this month. The data highlight the grave inadequacy of the U.S. Environmental Protection Agency’s (EPA) process for evaluating pesticide risks. Under current regulations, EPA requires chemical manufacturers to submit data only on singular active ingredients. Yet, pesticide products may be packaged or â€tank mixed’ with other, equally toxic pesticides without any obligation to determine the toxicity of the material that is actually being applied. Independent research is left to fill in these gaps, and the data increasingly shows that toxicity with pesticide mixtures amounts to a roll of the dice: sometimes combinations are less toxic, sometimes their toxicities are merely additive. But more often than not, pesticide mixtures result in synergistic effects that make the product significantly more toxic than either individual chemical alone. To understand how pesticide combinations are harming pollinators, scientists began with baseline data on the individual toxicity range that common pesticides pose to honey bee colonies. Research was conducted on honey bees reared in the Stoneville Wildlife Management Area […]

(Beyond Pesticides, February 15, 2023) Areas designated to protect insects fail to do so for over 75 percent of global species, according to a study, “Three-quarters of insect species are insufficiently represented by protected areas,” published in the online journal One Earth. Protected Areas (PAs) act as a safeguard for biodiversity. However, PAs in North America, Eastern Europe, Southeast Asia, and Australia do not meet the minimum coverage requirements to safeguard global insect species assessed in the study. PAs are discussed in the 2020 Nature article, “Area-based conservation in the twenty-first century,” in which the authors state that, in view of the global biodiversity crisis, national governments must do much more to increase protected areas with “coverage across different elements of biodiversity (ecoregions, 12,056 threatened species, â€Key Biodiversity Areas’ and wilderness areas) and ecosystem services (productive fisheries, and carbon services on land and seas).” The authors write, citing the UN Convention on Biological Diversity (to which the United States is not a signatory), “To be more successful after 2020, area-based conservation must contribute more effectively to meeting global biodiversity goals—ranging from preventing extinctions to retaining the most-intact ecosystems—and must better collaborate with the many Indigenous peoples, community groups and private initiatives […]

(Beyond Pesticides, February 14, 2023) The waterways that flow into the Great Lakes are experiencing year-round pesticide contamination that exceeds benchmarks meant to protect aquatic life, according to research published in Environmental Toxicology and Chemistry by scientists at the U.S. Geological Survey (USGS). “What you use makes it into the water,” study coauthor Sam Oliver, PhD, told the Milwaukee Journal Sentinel. These data buttress growing calls from pesticide reform advocates that new laws are needed to protect the nation’s increasingly threatened waters. USGS scientists conducted their analysis on 16 tributaries that feed into the Great Lakes, including sites that correspond to urban, agricultural, and undeveloped land. Samples were taken at locations closest to the lake the tributary flowed into over a period of roughly one year from October 2015 to September 2016. Each sample was tested for 231 pesticides and their breakdown products. Researchers used aquatic life benchmarks set by the U.S. Environmental Protection Agency (EPA), and created a relative hazard index (RHI) for the study to evaluate whether specific sites should be prioritized for further protections.  Across every sampled tributary, pesticides were found. Accordingly, 96% (190 out of 198) of samples taken contained pesticides or their breakdown products. […]

(Beyond Pesticides, February 1, 2023) Honey bee declines in the United States are “primarily related” to pesticide exposure, parasitic mites, and extreme weather conditions, research published by Penn State scientists have determined. Publishing the results in Scientific Reports, the researchers aim to provide a national overview of the range of factors harming bee colonies. “Some previous studies have explored several potential stressors related to colony loss in a detailed way but are limited to narrow, regional areas,” said study co-author Luca Insolia, PhD. “The one study that we know of at the national level in the United States explored only a single potential stressor. For this study, we integrated many large datasets at different spatial and temporal resolutions and used new, sophisticated statistical methods to assess several potential stressors associated with colony collapse across the U.S.” The results reinforce calls from bee health advocates in the U.S. and around the world: eliminate toxic pesticide use, the lowest hanging fruit contributing to pollinator declines. In order to create a more comprehensive national overview, geographers, entomologists, and statisticians all participated in the study, reviewing publicly available data on colony health, land use, weather, and other environmental factors over a five-year period from […]

(Beyond Pesticides, January 31, 2023) Glyphosate exposure induces oxidative stress in the body, a key biomarker known to heighten an individual’s risk of cancer, according to research published in the Journal of the National Cancer Institute by a team of scientists from the National Institutes of Health. The findings, which tracked study participants’ past use of glyphosate and exposure levels through urine, are particularly concerning in light of recent data showing that four out of five (81.6%) U.S. residents have detectable levels of glyphosate in their bodies. Despite these concerning data, evidence of widespread exposure to a carcinogen has so far failed to sway regulators at the U.S. Environmental Protection Agency, necessitating meaningful change by elected officials to reform pesticide regulation. Scientists began with the determination from the International Agency for Research on Cancer (IARC) that there is epidemiological evidence associating glyphosate with blood cancers like non-Hodgkin lymphoma, and strong evidence of carcinogenicity in laboratory animal research brought on by genotoxicity (DNA damage) and oxidative stress. “Oxidative stress occurs when the production of reactive oxygen species (ROS) and other free radicals exceeds the body’s antioxidant defense mechanisms, causing damage to DNA, proteins, and lipids,” the study explains. This process can […]

(Beyond Pesticides, January 25, 2023) Populations of the western bumblebee are in free fall, with 57% declines across the species’ historical range, finds new research led by scientists at the U.S. Geological Survey. These data are in line with trends for other once common bumblebees in the United States, like the rusty patched and American, of which the former is now listed as endangered and the latter is under consideration. Most critically, the study authors did not simply generalize the most likely and common reasons, but instead establish the contribution that pesticide use, climate change, and land use changes have on western bumblebee declines. As the study shows, both the drivers and solutions to pollinators declines are in human hands, necessitating a broad rethinking of the nation’s approach to energy use and food production. The western bumblebee has been under considerable stress for decades. In the 1990s, there were attempts to commercialize the species as a greenhouse pollinator. This industrial approach resulted in the spread of a fungal disease called Vairimorpha bombi, and captive rearing of the western bumblebee was eventually halted and deemed untenable. These dislocations resulted in local declines of the species in certain regions of U.S. Northwest […]

(Beyond Pesticides, January 19, 2023) Research published in Environmental Health Perspectives finds the presence of nine various neonicotinoids (neonics) and six neonic metabolites within human cerebrospinal fluid (CSF). CSF is an essential part of the central nervous system (CNS), especially for CNS development. Specific chemical biomarkers (measurable indicators of biological state), like pesticides, found in CSF are useful for diagnosing and evaluating numerous neurological diseases. The nervous system is an integral part of the human body and includes the brain, spinal cord, a vast network of nerves and neurons, all of which are responsible for many of our bodily functions—from sensed to movement. However, mounting evidence over the past years shows that chronic exposure to sublethal (low) levels of pesticides can cause neurotoxic effects or exacerbate preexisting chemical damage to the nervous system. The impacts of pesticides on the nervous system, including the brain, are hazardous, especially for chronically exposed individuals (e.g., farmworkers) or during critical windows of vulnerability and development (e.g., childhood, pregnancy). Researchers identify the role agricultural chemicals play in CNS impacts causing neurological diseases, like amyotrophic lateral sclerosis (ALS) and Parkinson’s disease, dementia-like diseases such as Alzheimer’s, and other effects on cognitive function. Over 300 environmental contaminants and their byproducts, including pesticides, are chemicals commonly present in human blood […]

(Beyond Pesticides, January 18, 2023) Sunflower plantings have the potential to significantly reduce mite infestations in nearby honey bee colonies, according to research recently published in the Journal of Economic Entomology by researchers with the U.S. Department of Agriculture (USDA). With pollinators under threat from pesticides, climate change, loss of habitat, and the spread of disease and parasites, sustainable methods that address multiple factors at once are needed. This study points to a way to address destructive Varroa mites, while reducing the need for in-hive use of miticides that can likewise harm colony health. “If sunflowers are as big of a factor in mite infestation as indicated by our landscape-level correlations … having a few more acres of sunflower within a mile or two of apiaries could bring colonies below the infestation levels that require treatment of hives with acaracides (i.e., mite-controlling chemicals),” said lead author Evan Palmer-Young, PhD, of USDA’s Bee Research Lab in Beltsville, MD. Prior research has pointed to sunflower pollen as a potential benefit for a number of common bee diseases and infestations, including the Varroa mite, the fungal parasites Nosema spp, and various viruses. Investigations went through four different experiments aimed at characterizing any potential […]

(Beyond Pesticides, January 13, 2023) The pastoral image that “farming” may still conjure for many will suffer a shock as Beyond Pesticides reports, in this Daily News Blog, about developments in the agricultural universe, including massive consolidation in the industries that supply seeds and agrochemicals to conventional farmers. A January 2023 report from Philip H. Howard, PhD updates previous work of his (see here and here) on these trends during the past couple of decades, and focuses on the most-recent (2018–2022) developments. The net conclusion is that the four largest agrochemical companies — Bayer (Monsanto), BASF, Corteva, and Sinochem (which recently subsumed ChemChina/Syngenta) — are exerting increasing leverage over an agricultural system that concentrates power and wealth, while threatening health, the environment, and access to food. The machinations of these industries for profit, power, market penetration, and privatization of aspects of the natural world are hardly new. The National Sustainable Agriculture Coalition (NSAC) summarizes some aspects of the situation in saying, “Land and seed once belonged to no one and were shared by all, replicating the giving essence of the natural world. Today, these precious resources are tightly controlled and commoditized inputs. The modern U.S. food and agriculture system is designed to […]

(Beyond Pesticides, January 11, 2022) Neonicotinoid insecticides can have detrimental effects on liver health, according to research published in the Journal of Hazardous Materials. While this is the first study to investigate how these chemicals harm the liver, there is increasing evidence that neonicotinoids, otherwise notorious for their effects on pollinators and aquatic life, can cause direct harm to human health. As the U.S. Environmental Protection Agency (EPA) continues to protect the pesticide industry from any measure of meaningful regulation around these hazardous products, the job falls to advocates to place pressure on elected officials to make the changes necessary to safeguard long-term health and well-being. Scientists postulated that neonicotinoids are neither metabolized by the liver nor excreted by urine. To test that hypothesis, 201 individuals from a hospital in China were enrolled into a study. Of the enrolled, Â 81 were cancer patients, and 120 were not. These individuals underwent a procedure called endoscopic retrograde cholangiopancreatography whereby samples of their bile, a fluid produced in the liver, were retrieved and analyzed. Researchers also performed a series of blood tests, measuring a range of biomarkers, including cholesterol, bilirubin, bile acids, white blood cells, platelets, and others. Lastly, scientists determined the amount […]

(Beyond Pesticides, January 10, 2023) Pollinator losses are responsible for reducing the global production of nuts, fruits, and vegetables by 3-5%, and this loss of healthy, nutrient-dense food is resulting in over 425,000 excess deaths each year, according to research published late last year in Environmental Health Perspectives. While the connection between pollination, food production and health is intuitive, the study’s ability to trace how these impacts are directly harming the well-being of people living right now is shocking, and is a clear sign that pollinator losses must be taken seriously and addressed through meaningful action. To those who consider the decline of pollinators to be some vague, amorphous future threat, let this study end that myth. According to researchers, “Today’s estimated health impacts of insufficient pollination would be comparable to other major global risk factors: those attributable to substance use disorders, interpersonal violence, or prostate cancer. Per a United Nations report, 75 percent of the world’s food crops depend at least in part on pollination, with pollinators contributing an estimated $235 to $577 billion to global crop production annually. Pollinator declines are already adversely impacting food production. A 2016 paper by many of the scientists in the current study […]

(Beyond Pesticides, January 9, 2023) The Biden EPA still needs a new vision in order to meet the existential crises in public health, climate change, and biodiversity. The Trump Environmental Protection Agency (EPA) reversed in four years much of the progress made by the EPA in decades. Despite a broad new perspective embodied in President Biden’s Executive Memorandum (EM) Modernizing Regulatory Review issued on his first day in office, the Biden EPA has not adopted a new direction for regulating pesticides. Tell President Biden, EPA, and Congress to adopt a new direction for pesticide regulation. Immediately following his inauguration, President Joe Biden issued the EM, which directs the heads of all executive departments and agencies to produce recommendations for improving and modernizing regulatory review, with a goal of promoting public health and safety, economic growth, social welfare, racial justice, environmental stewardship, human dignity, equity, and the interests of future generations. This EM could reverse the historical trend of status-quo regulatory reviews required by the White House Office of Management and Budget (OMB) that typically support vested economic interests of polluters (e.g., petroleum-based pesticide and fertilizer manufacturers). The President’s EM sets the stage for the adoption of agency policy across government to […]

(Beyond Pesticides, January 4, 2022) A study published in Environmental Science and Technology finds neonicotinoids (neonics) and their breakdown products (metabolites), like other chemical pesticide compounds, can readily transfer from mother to fetus. The National Health and Nutrition Examination Survey (NHANES) finds U.S. pregnant women experience frequent exposure to environmental pollutants that pose serious health risks to both mother and newborn. Many known pollutants (i.e., heavy metals, polychlorinated biphenyl, and pesticides) are chemicals that can move from the mother to the developing fetus at higher exposure rates. Hence, prenatal exposure to these chemicals may increase the prevalence of birth-related health consequences like natal abnormalities and learning/developmental disabilities. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Moreover, a mother’s pesticide exposure can have a stronger association with health disorders than childhood exposure, and a newborn can still encounter pesticides. Therefore, it is essential to understand how pesticides impact the health and well-being of individuals during critical developmental periods. Beyond Pesticides has covered a variety of pregnancy risks from pesticides and other toxic chemicals, including these in just the last three years: pesticides and children’s sleep disorders; prenatal exposures to a multitude of chemicals; insecticides and childhood leukemia; insecticides and Attention Deficit/Hyperactivity Disorder. The study […]

(Beyond Pesticides, December 16, 2022) A report released last week — Merchants of Poison: How Monsanto Sold the World on a Toxic Pesticide — exposes not only Bayer/Monsanto malfeasance in its “promotion” of its glyphosate-based herbicide products, including the notorious Roundup®, but also, the broader landscape of corporate efforts to white- or green-wash products that companies know are harmful to people and the environment. The report was issued by U.S. Right to Know (USRTK, a nonprofit investigative research group focused on promoting transparency for public health), Friends of the Earth (FOE), and Real Food Media. It carries the pithy subtitle, “A case study in disinformation, corrupted science, and manufactured doubt about glyphosate,” a description cited by the Friends of the Earth press release as “at the core of the pesticide industry’s public relations playbook.” Beyond Pesticides welcomes this report, which comports with much of our previous coverage of the pesticide industry’s egregious misbehavior, and of glyphosate, the world’s most widely used herbicide. FOE calls the report the “first comprehensive review” of the Bayer/Monsanto “defense strategy” employed in attempts to deny science, manufacture doubt, and discredit critics who have researched, reported on, and/or advocated against the company’s flagship glyphosate products because […]

(Beyond Pesticides, December 6, 2022) Persistent organic pollutants (POPs)—including banned pesticides—present a health risk to humpback whales (Megaptera novaeangliae), according to a study published in Environmental Pollution. Regarding female humpback whales, levels of POPs in blubber are higher in juveniles and subadults than in adults, primarily from the transference of contaminants from the mother to her calf. Organochlorine compounds (OCs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are well-known persistent organic pollutants. The international Stockholm Convention treaty (signed by 152 countries, but not the U.S.) banned these primary pollutants of concern (UNEP, 2009) in 2001 (taking effect in 2004) because of their persistence, toxicity, and adverse effects on environmental and biological health. These pollutants have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. However, these chemicals can remain in the environment for decades and interact with various current-use pesticides, including organophosphates, neonicotinoids, and pyrethroids. Although various studies demonstrate the volatile, toxic nature of POPs, much less research evaluates the impact POPs have on maternal offloading or transfer of contaminates to offspring and respective health consequences. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one […]

(Beyond Pesticides, December 1, 2022) The U.S. Environmental Protection Agency (EPA) must put measures in place to protect endangered species from the hazardous insecticide cyantraniliprole before September 2023. The requirements stems from a recent federal appeals court ruling that found EPA in violation of its statutory obligations under the Endangered Species Act (ESA). The agency originally lost its legal case on this chemical in 2017, but has since done nothing to fulfill the initial court order, necessitating further litigation by conservation groups. “It’s outrageous that the EPA is thumbing its nose at a federal court order even as cyantraniliprole wreaks havoc on our most endangered wildlife,” said Jonathan Evans, environmental health legal director at the Center for Biological Diversity. “The EPA has acknowledged that this pesticide is incredibly toxic to bees and other invertebrates, but the agency is so accustomed to putting the profits of the pesticide industry ahead of its duty to protect human health and our environment that for years it simply ignored a direct court order.” Cyantraniliprole is a systemic insecticide registered for use in 2014. It presents similar risks to pollinators and wildlife as other widely used systemics, such as the neonicotinoid class of chemicals. Its […]

The Forum headliners are (i) Rachel Bezner Kerr, PhD, Cornell University professor just back from COP 27 [27th Conference of the Parties to the United Nations Framework Convention on Climate Change] and co-author of the definitive United Nations (UN) report on climate and food production and (ii) Andrew Smith, PhD, chief operating officer of the Rodale Institute and coauthor of several landmark reports on soil biology and carbon sequestration, including the just released Farming Systems Trial—40-Year Report. With livability of the planet on the brink, the speakers at the upcoming Forum make the case to immediately reverse the increase of greenhouse gases, carbon dioxide, nitrous oxide, and methane to stop the changes on the horizon that destroy life—from floods, fires, and associated climate-induced hazards to food production. The good news, according to the scientists, is that there are solutions available now in the agricultural and land management sectors that can reverse the threat if dramatic changes are made. Dr. Bezner Kerr, […]

(Beyond Pesticides, November 23, 2022) A new study throws into question the value of the pest management concept of setting action levels around pest infestations. In the course of watermelon production over a span of two years, pollination, not pest levels, was the key determining factor for yield. “These data advocate for a reprioritization of management, to conserve and protect wild bee pollination, which could be more critical than avoiding pest damage for ensuring high yields,” the study, published in Proceedings of the Royal Society B, indicates. Action levels are considered an important aspect of an integrated pest management (IPM) approach in agriculture, whereby a pest infestation reaches levels considered economically unacceptable, leading to a decision to engage in pest control. The concept of IPM however has been influenced by the chemical industry over the decades since its original definition and recent data indicates that it has failed to stop toxic pesticide use. The original intent of IPM was the adoption of preventive practices and utilization of nonchemical tools, placing pesticide use as a last resort when pest control is warranted. However, farms that self-identify as IPM operations use pesticides, sometimes as the first line of defense, while attempting to […]

(Beyond Pesticides, November 15, 2022) Spraying a flowering plant with synthetic fertilizers makes it less attractive to bumblebees, according to research published this month in PNAS Nexus.  “A big issue is thus—agrochemical application can distort floral cues and modify behaviour in pollinators like bees,” said study author Ellard Hunting, PhD, of the University of Bristol, UK. The findings underscore the limited understanding that proponents of chemical agriculture have for the complex processes that food production relies upon and reinforce calls for a broad scale transition to regenerative, organic farming practices. Scientists began with the knowledge that spray applications of various agrichemicals affect the visitation patterns of bumblebees and other pollinators through a range of different processes. Past research finds that notorious bee-killing neonicotinoid insecticides not only kill bees outright, but also result in a range of complex damage, including their ability to impede bees’ olfactory senses and adversely affect their vision and flying ability. Other chemicals like glyphosate weaken bees’ ability to distinguish between colors.  A growing area of research is investigating the ways in which pollinators use static electric fields surrounding flowers to find food sources. A 2013 study found that bumblebees use floral electrical fields to discriminate […]

(Beyond Pesticides, November 7, 2022) The Maine Congressional delegation — Senators Collins (R) and Angus King (I), and Representatives Chellie Pingree (D) and Jared Golden (D), along with New Hampshire Senator Jeanne Shaheen (D) — have  introduced a bipartisan bill — the Relief for Farmers Hit with PFAS Act — to help farmers who have been adversely affected by the scourge of PFAS (perfluoroalkyl and polyfluoroalkyl substances) chemicals. The bills are the identical S. 5070 and H.R. 9186, both titled “Relief for Farmers Hit with PFAS Act.” Tell your U.S. Senators and Representative to cosponsor the Relief for Farmers Hit with PFAS Act. If they are already cosponsors, thank them. Tell EPA to stop the spread of legacy chemicals. PFAS chemicals, also known as “forever chemicals,” are legacy contaminants or those whose historical use, including many decades ago in some instances, has led to their toxic persistence in the environment and in organisms. PFAS chemicals are not the only legacy contaminants. Others include wood preservatives, DDT, dioxins, and the termiticide chlordane. Unfortunately, some of these continue to be added to the environment, sometimes inadvertently, but also intentionally, particularly through pesticide use. As indicated by the title of these bills, farmers […]

(Beyond Pesticides, November 1, 2022) Honey bees exposed to a combination of multiple pesticides suffer a reduced lifespan and experience adverse changes to their gut microbiome, increasing susceptibility to pathogens and disease. This finding comes from a study published recently in Science of the Total Environment, which examines the interactions between the insecticides flupyradifurone and sulfoxaflor and the fungicide azoxystrobin on honey bee health. Both insecticides studied are considered substitutes for notorious bee-killing neonicotinoid insecticides, which move through the vascular system of the plant and contaminates its pollen, nectar, and guttation droplets. As declines in pollinator and insect life continue throughout the world, it is critical not only to understand and restrict widely used chemicals like neonicotinoids, but also the regrettable and deleterious substitutions the agrichemical industry has developed to replace them. As the present study reveals, pesticide risk assessments do not inadequately capture the range of harm that can result when pesticides are combined, necessitating a shift toward safer, alternative, and regenerative organic farming systems that do not use these dangerous chemicals. To better understand the impacts of combined pesticide exposure on honey bees, researchers employed three colonies located in Germany’s Martin Luther University that were inspected and free […]

(Beyond Pesticides, October 27, 2022) A study published in Environment International adds to the growing body of research evaluating the association between neonicotinoid insecticides (neonics/NIs) and breast cancer. Past studies suggest neonics act as endocrine disruptors, affecting the development and regulation of estrogen hormones that promote breast cancer. However, this study is one of the few to evaluate the toxicological and molecular mechanisms involved in initiating breast cancer events. According to the Centers for Disease Control and Prevention (CDC), breast cancer is a disease that causes breast cells to grow out of control, with the type of breast cancer depending on the cells themselves. Most common forms of breast cancer have receptors on the cell surface that can increase cancer growth when activated by estrogen, progesterone, or too much of the protein called HER2. One in ten women will receive a breast cancer diagnosis, and genetics can only account for five to ten percent of cases. When a cancer cell lacks receptors for these molecules, G protein-coupled estrogen receptors (GPERs) are an essential biological target of estrogen and plays a role in hormone-dependent cancer development. GPERs regulate estrogen through non-genetic cellular pathways, forgoing attachment to standard molecular receptors, leading to triple-negative breast cancer (TNBC). Although past […]

(Beyond Pesticide, October 20,2022) Exposure to environmentally relevant levels of glyphosate-based herbicides (GBHs) weakens bumblebees’ (Bombus Terrestris) ability to distinguish between colors or fine-color discrimination. According to research published in Science of The Total Environment, a lack of fine-color discrimination skills can threaten bumble bee survivability through impact on colony fitness and individual foraging success. Much research attributes the decline of insect pollinators (e.g., commercial and wild bees and monarch butterflies) over the last several decades to the interaction of multiple environmental stressors, from climate change to pesticide use, disease, habitat destruction, and other factors. In the U.S., an increasing number of pollinators, including the American bumblebee and monarch butterfly, are being added or in consideration for listing under the Endangered Species Act, with specific chemical classes like systemic neonicotinoid insecticides putting 89% or more of U.S. endangered species at risk. Pollinator decline directly affects the environment, society, and the economy. Without pollinators, many plant species, both agricultural and nonagricultural, will decline or cease to exist as U.S. pollinator declines, particularly among native wild bees, limits crop yields. In turn, the economy will take a hit, as much of the economy (65%) depends upon the strength of the agricultural sector. As science shows, pesticides are one of the most significant stressors […]
