(Beyond Pesticides, December 21, 2022) Imagine plucking a flower and being able to find out every insect that recently visited that plant. Utilizing cutting-edge metabarcoding techniques, a team of Danish researchers has made that possibility a reality. By evaluating the environmental DNA (eDNA) left behind by insect pollinators alongside visual assessment surveys, a new study is providing an innovative way for farmers to improve pollination and protect on-farm biodiversity. Ultimately, study author Lene Sigsgaard, PhD, of the University of Copenhagen believes that, “With more knowledge of the pollinators in apples and other crops, we can begin to provide tailor-made flower mixes for individual crops, and improve our knowledge on the value of the surrounding landscape for wild pollinators.” Scientists focused on four different apple orchards throughout Denmark, three of which utilize pesticides (though only one sprayed during the study period), and another following organic practices. For each orchard, five apple flowers were collected from four separate rows. These flowers were then brought to the laboratory from DNA extraction. Scientists also conducted visual monitoring, whereby an observer stood between two orchard rows and recorded all flower visitors within roughly eight feet of themselves. The two methods of observation provide somewhat differing, […]

(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 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 […]

(Beyond Pesticides, November 24, 2021) On Thanksgiving, thank you for being a part of Beyond Pesticides and sharing and contributing to the vision necessary to protect the web and the fragility of life. We believe that there is no time like Thanksgiving to think about how we can more effectively join together as families and communities across divisions and different points of view to find a common purpose in protecting the health of the environment and all that inhabit it. Unfortunately, a host of pesticides, genetically engineered materials, and others in conventional Thanksgiving foods impact human health and threaten the environment. With far too many adverse health and ecological effects associated with toxic chemicals, organic practices are viable solutions to mitigate pesticide contamination and subsequent exposure. Read on as we consider the range of challenges we must confront and the solutions that can bring us all together. Additionally, you can help Beyond Pesticides in educating and building a movement that will bring long-needed protection to humans, animals, and the entire environment by attending the third seminar on November 29 on Climate during the 2022 National Forum Series, Health, Biodiversity, and Climate: A Path for a Livable Future. The National Forum […]

(Beyond Pesticides, November 11, 2022) A paper published in Trends in Ecology & Evolution in late October sounds an unnerving alarm about the globally ubiquitous use of herbicides and the ecological destruction being caused. It asserts that widespread environmental contamination with these herbicide compounds is influencing soil, plant, and animal microbiomes in ways that are not only not well understood, but also, can have significant impacts on the functioning of organisms and their ecosystems — with evolutionary implications. Impacts of herbicides on microbiota in soils include, for example, those on nutrient cycling, and altered organism and plant performance, which can affect pollination and animal consumption of plants. This research reinforces what Beyond Pesticides wrote in covering a 2021 study: “The popular herbicide glyphosate negatively affects microbial communities, indirectly influencing plant, animal, and human health. Exposure to sublethal concentrations of glyphosate shifts microbial community composition, destroying beneficial microorganisms while preserving pathogenic organisms.” Herbicides are a category of pesticide used to control weeds in agriculture and commercial forests, on managed landscapes, byways, gardens, and lawns, and directly on surface waters to control aquatic weeds. They are designed to kill “target” plant species considered undesirable in any of those circumstances. Herbicide use has exploded […]

(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 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 […]

(Beyond Pesticides. October 14, 2022) A team of researchers has taken on the challenge of integrating data from multiple and disparate sources in order to devise tools with which scientists can evaluate pollinator pesticide exposures and impacts more effectively at “landscape scale” (and at real-life exposure levels). Accessing data that are useful and relevant at this landscape level has been a significant problem for researchers and conservationists. This “zoomed out” view is critical because pollinators are highly mobile across thousands of meters of foraging area. A functional understanding of the risks pollinators encounter in their territories requires integrated data at this level, as opposed to the large geographic areas across which pesticide use is typically tracked. The team’s paper on their work — Putting pesticides on the map for pollinator research and conservation — was published in Nature.com in mid-September. Pollinators are essential to healthy ecosystems and to a third of human food sources, as well as to plants used for commercial seed production. As the authors note, nearly 90% of flowering plant species benefit from the services of pollinators that help plants set their seeds and produce flowers and fruit (this last term includes foods widely considered to be “vegetables,” […]

(Beyond Pesticides, October 12, 2022) The U.S. Environmental Protection Agency (EPA) is asking a federal court for permission to go back and reconsider its decision to reapprove use of the highly hazardous herbicide paraquat, according to a filing submitted by the agency late last month. Advocates see the move as encouraging, since meaningful EPA action on this Parkinson’s-linked chemical is long overdue. Last year, advocates condemned the Biden Administration for its reapproval of the weed killer with fewer protections than those proposed by the Trump Administration, marking a deeply concerning sign for pesticide reform campaigners looking to the administration for positive change. EPA’s request is the result of a legal challenge brought by the California Rural Legal Assistance Foundation, Earthjustice, Farmworker Association of Florida, Pesticide Action Network, and the Michael J. Fox Foundation for Parkinson’s Research.  The groups argued that the agency’s decision to reregister paraquat was not legal based on substantial evidence that the chemical poses unreasonable risks to human health and the environment. While EPA made its initial decision to reapprove paraquat in the late days of the Trump Administration, it was under the Biden Administration that the agency reversed a proposed ban on aerial use, permitting broad-scale […]

(Beyond Pesticides, September 27, 2022) Exposure to widely used neonicotinoid insecticides harms amphibians at multiple life stages, adversely affecting their ability to survive in the wild, according to research published in the Journal of Zoology. As long-lived, systemic insecticides, neonicotinoids are consistently found in U.S. waterways,  often above federal safety limits, making these findings particularly dangerous for frogs and other amphibians throughout the country. As troubling data piles up on this class of dangerous insecticides, which are damaging pollinators, birds, deer, aquatic wildlife, and human health, it is left to the public to place pressure on federal regulators and members of Congress to act. To understand the impact of neonicotinoids on amphibian life stages, researchers conducted a range of  experiments. These were designed to investigate how exposure to the neonicotinoid imidacloprid affected larval survival, sexual development, locomotor skills, and avoidance behavior of the wood frog (Rana sylvatica). Larval survival was examined by exposing tadpoles to 10 parts per billion (ppb) of imidacloprid, a rate lower than the lethal concentration expected to kill half of other frogs species in acute toxicity tests. Four treatment protocols were established, adding the variable of natural pond drying to half of the tested frogs to […]

(Beyond Pesticides, September 23, 2022) According to a September 15 Environment California press release, California Department of Pesticide Regulation (CDPR) data confirm more bad news on neonicotinoid (neonic) contamination: nearly all urban waterways in three counties show the presence of the neonic imidacloprid at levels above the U.S. Environmental Protection Agency’s (EPA’s) chronic benchmark for harm to aquatic ecosystems; in five other counties, well over half showed its presence at similar levels. Neonic use is strongly correlated with die-offs and other harms to a variety of bees and pollinators, and to other beneficial organisms. These startling metrics will make the state’s efforts to protect such organisms even more challenging, according to Environment California (EC). See Beyond Pesticides’ Poisoned Waterways report for a deep dive on neonics and their impacts in U.S. rivers, lakes, and streams. The data represent 405 surface water samples taken between 2000 and 2020; those from urban waterways in Los Angeles, Orange, and San Diego counties showed that nearly 92% are contaminated at EPA benchmark violative levels; in Alameda, Contra Costa, Placer, Sacramento, and Santa Clara counties, 58% of waterways showed such levels. Many of the counties with significant contamination are in the central coast and southern regions of […]

(Beyond Pesticides, September 21, 2022) Strawberry plants pollinated by wild bees exposed to neonicotinoid insecticides produce smaller berries than those pollinated by unexposed bees, finds research published in the journal PLOS One. The findings are yet another piece of evidence pointing to the need for major reforms in the way pesticides are evaluated and pollinators are protected in the United States. As decades of evidence have piled up on the dangers posed by long-lived, systemic, neonicotinoid insecticides, the U.S. Environmental Protection Agency (EPA) has done little to address the damage to pollinator populations, while needed legislation, the Saving America’s Pollinators Act, has languished in Congress without a hearing or a vote, despite having over 75 cosponsors. This new study describes a novel consideration for how neonicotinoids may harm pollinators and impact the food supply. “Previous studies have shown that clothianidin affects wild bees negatively in terms of foraging speed, development and reproduction. Our results indicate that it can also impair the bees’ ability to pollinate strawberry flowers,” says study coauthor Lina Herbertsson, PhD. Scientists established 12 outdoor cages each with 10 strawberry plants and 11 canola plants. For half of the cages, the canola plants were grown with seeds coated […]

(Beyond Pesticides, September 15, 2022) A review published in Scientific African finds pesticide exposure contributes to the increase in non-communicable diseases (NCDs) in Tanzania, reflecting implications for global health. There are four main NCDs, including cardiovascular diseases, cancers, respiratory diseases, and endocrine-disrupting diseases like diabetes. These diseases have no bacterial, viral, or fungal causes, but are chronic diseases with risk factors like genetics, tobacco/alcohol use, physical activity, and diet, thus lacking transmission between people. However, research is now investigating the role environmental factors play in NCD risks, such as outdoor and indoor air pollution, exposure to chemicals, radiation, and occupation. Regardless of whether working together or separately, these risk factors contribute to NCDs and subsequent health conditions. Non-communicable diseases are on the rise, and the World Health Organization (WHO) classifies non-communicable diseases as the number one cause of death globally, affecting 41 million individuals. Moreover, WHO estimates NCD death rates to increase by 17 percent in the next decade, significantly surpassing deaths from communicable, maternal, perinatal, and nutritional diseases combined. Therefore, the report notes, “This review is informative to the policy, practices, and intervention towards the existing situation of pesticides in Tanzania. In addition, it calls for further investigation of the absence of data […]

(Beyond Pesticides, September 13, 2022) Every store-bought milkweed sample tested in a recent study contains multiple toxic pesticides, placing monarchs reliant on these plants in harm’s way at a time the species can ill afford any further loss to its population. Pollinator declines have influenced many residents throughout the U.S. to take action into their own hands and transform their home yards or businesses into an oasis for bees, birds, and butterflies. Yet the recent study published in Biological Conservation finds that many retailers are dousing their ‘wildlife-friendly’ plants with pesticides that put this vulnerable species in further danger. “That was the most shocking part,” said lead author Christopher Halsch, a doctoral study at University of Nevada, Reno. “The fact that plants labeled as potentially beneficial or at least friendly to wildlife are not better and in some cases might be worse than other plants available for purchase. This research sheds light on how pesticides may impact western monarchs, but many other butterflies are facing even steeper population declines, and pesticides are likely one driver.” Testing was conducted by purchasing milkweed plants at 33 different stores spanning 15 different states. A sample of each plant was cut after purchase, and […]

(Beyond Pesticides, August 26, 2022) New research from a team in California finds one-third of pesticides it reviewed — including glyphosate, paraquat dichloride, and oxyfluorfen — to be associated with the development of thyroid cancer. Researchers investigated the links between exposure to pesticides — including 29 that cause DNA cell damage — and the risk of this cancer. The researchers also find that in all the single-pollutant models they employed, paraquat dichloride — a widely used herbicide — was linked to this cancer. In 2021, Beyond Pesticides covered research by the U.S. National Institutes of Health (NIH) that demonstrated that exposures to lindane and metalaxyl also cause heightened risk of thyroid cancer. These study findings add to the already considerable concern about pervasive pesticide exposure — not only among farmers and applicators, but also in the general population. It is worth noting that, in addition to elevated thyroid cancer risks, multiple pesticides can cause other health damage. Paraquat is also acutely toxic, and can cause longer-term reproductive, renal, and hepatic damage to humans; it is toxic to birds, fish, and other aquatic organisms, and slightly so to honeybees. Glyphosate, as Beyond Pesticides has written frequently, is carcinogenic, and is associated […]

(Beyond Pesticides, August 23, 2022) Bees exposed to systemic insecticides become disoriented and cannot walk straight, showing evidence of brain damage in areas that coordinate movement, according to research published in Frontiers in Insect Science. Although scientific studies and regulatory determinations have already provided ample evidence implicating systemic insecticides like the neonicotinoids and sulfoxaflor with pollinator danger and decline, new research continues to fill in the remaining gaps. “Here we show that commonly used insecticides like sulfoxaflor and the neonicotinoid imidacloprid can profoundly impair the visually guided behavior of honey bees,” said lead author Rachel H Parkinson, PhD, a scientist at the University of Oxford. “Our results are reason for concern because the ability of bees to respond appropriately to visual information is crucial for their flight and navigation, and thus their survival.” Honey bees rely on landmarks, the direction of sunlight, and wide-field visual motion to orient themselves in a landscape, find nectar and pollen, and bring it back to the hive. While sunlight provides a compass, wide-field visual motion helps bees adjust speed and altitude, and determine where they are relative to known landmarks. Worker bees use this innate ability to reorient themselves to food or their hive […]

(Beyond Pesticides, August 2, 2022) Members of the United States Senate are calling on the U.S. Fish and Wildlife Service (FWS) to phase out the use of toxic pesticides in National Wildlife Refuges in order to protect declining wildlife species and the country’s unique natural resources. Led by Senator Cory Booker (D-NJ), the senators sent a letter to FWS Director Martha Williams urging FWS to “expeditiously begin a rulemaking process to phase out the use of agricultural pesticides on National Wildlife Refuges.” The move comes at a time when native wildlife and the ecosystems humans rely upon are under greater threats than ever before from climate change, habitat destruction, and the indiscriminate use of toxic pesticides. “The Refuge System was established to provide sanctuary for listed threatened and endangered species, migratory birds, and other wildlife,” wrote the senators in a letter to U.S. Fish & Wildlife Director Martha Williams. “The Refuges’ migratory sanctuary and breeding grounds are especially critical for North American birds, as they have faced precipitous population declines; there are 3 billion fewer breeding birds in North America than there were in 1970. Unfortunately these birds and other threatened species are being put at risk by pesticide use […]

(Beyond Pesticides, June 24, 2022) As reported by the Center for Food Safety (CFS), on June 16 the Environmental Protection Agency (EPA) released final Biological Evaluations, for three neonicotinoid insecticides, that indicate that these pesticides are “likely to adversely affect” the vast majority of endangered or threatened species and/or their designated critical habitats. These evaluations for imidacloprid, clothianidin, and thiamethoxam have been a long time coming, and represent, according to the Center for Biological Diversity (CBD), the first time EPA “has completed biological evaluations of any neonicotinoids’ harms to the nation’s most imperiled plants and animals.” These evaluations evidence what CFS, CBD, Beyond Pesticides, and others have maintained for years: that neonicotinoid compounds are very serious threats to the survival and well-being of myriad organisms and habitats. A Biological Evaluation (BE) is an EPA analysis of potential harmful impacts of a registered pesticide on any species federally listed, per the Endangered Species Act, as endangered or threatened, or on their critical habitats. EPA was legally required to issue the determinations by the June 2022 deadline, per CFS litigation and a subsequent 2019 legal settlement. EPA was the defendant in 2017 litigation brought by CFS, with Beyond Pesticides, several beekeepers, and the Center for Environmental […]

(Beyond Pesticides, June 21, 2022) June 20-24 is Pollinator Week, during which we recognize—and take action to protect—this important ecosystem link. Pollinators––bees, butterflies, birds, bats, and other organisms––make a critical contribution to plant health, crop productivity, and the preservation of natural resources, but their existence is threatened by their pesticide-contaminated habitat. Pesticides have consistently been implicated as a key contributor to dramatic pollinator declines. Of the 100 crop varieties that provide 90% of the world’s food, 71 are pollinated by bees. Honey bees alone pollinate 95 kinds of fruits, nuts and vegetables, such as apples, avocados, almonds, and cranberries. Take action to protect pollinators. Providing protection for pollinators also protects the ecosystem in which they live. That protection requires eliminating harm as well as providing safe habitats where they can live and reproduce.  Provide organic habitat on your own property and encourage your town to go organic. Since plant starts in many garden centers across the country are grown from seeds coated with bee-toxic neonicotinoid pesticides, or drenched with them, Beyond Pesticides has compiled a comprehensive directory of companies and organizations that sell organic seeds and plants to the general public. Included in this directory are seeds for vegetables, flowers, and herbs, as well as […]

(Beyond Pesticides, June 19, 2022) On Juneteenth Day, we commemorate the abolition of slavery and celebrate human freedom. At the same time, we recognize that we have significant work to do to eliminate systemic racism and advance environmental justice. We strive to ensure that people of color are not disproportionately harmed by pesticides and other toxic chemicals—from production, use, to disposal—and that all people have access to sustainable and organic food and organically managed communities. Acute and chronic exposure to chemicals like pesticides cause a plethora of harmful effects, including (but not limited to) brain and nervous system disorders, birth abnormalities, cancer, developmental and learning disorders, endocrine disruption, immune disorder, and reproductive dysfunction, among others. However, people of color may experience more servere health effects from exposure, resulting in elevated rates of diseases. Communities of color and those living in low-socioeconomic conditions experience an inequitable number of hazards, including toxic waste plants, garbage dumps, and other sources of environmental pollution and odors that lower the quality of life. Therefore, these populations experience greater exposure to harmful chemicals and suffer from health outcomes that affect their ability to work and learn. When discussing health disparities and environmental justice, we need to […]

(Beyond Pesticides, June 14, 2022) The ringleader of a pesticide smuggling operation conducted across the United States border with Mexico has been sentenced to eight months in prison by a U.S. District Court Judge. According to a press release by the U.S. Attorney’s Office for the Southern District of California, Sofia Mancera Morales used individuals recruited over social media Bovitraz and Taktic, pesticide products banned in the US that pose hazards to pollinators and cancer risks to humans. “In exchange for ill-begotten profits, this cavalier smuggling operation was more than willing to risk the public’s health and the honeybee industry, which is critical to pollinating our food supply,” said U.S. Attorney Randy Grossman. While the Department of Justice deserves praise for this enforcement action, health and environmental advocates say that more must be done to stop illegal pesticide sales. A quick search for the two pesticide products in question brings up webpages, including well-known sites like Etsy.com, where the same illegal pesticides cited in this case are currently being sold to U.S. consumers. Over Facebook, Ms. Morales offered to pay individuals between $40-150 per package of pesticide products they delivered across the border. Those recruited were instructed to open a […]

(Beyond Pesticides, June 7, 2022) Bumblebee colonies exposed to low levels of the weed killer glyphosate are unable to adequately regulate nest temperature, imperiling the next generation of bumblebees and long-term colony growth and survival. This latest finding, published this month in the journal Science, is a stark reminder that a pesticide does not have to kill an animal outright in order to create effects that ultimately result in death and population declines. “Sublethal effects, i.e. effects on organisms that are not lethal but can be seen, for example, in the animals’ physiology or behaviour, can have a significant negative impact and should be taken into account when pesticides are approved in future,” said Anja Weidenmüller, PhD, of the University of Konstanz, Germany. With regulators at the U.S. Environmental Protection Agency (EPA) refusing to adequately account for sublethal impacts, and myopically focused on the acute effects of pesticide exposure, bumblebee populations in the United States are in free fall and require urgent protective action. To better understand how glyphosate exposure affects bumblebee colony growth and brood (young larval bee) development, researchers first split colonies in two. One side of the colony was fed sugar water containing 5mg/liter of glyphosate, while […]

(Beyond Pesticides, June 6, 2022) In spite of the known harm to migratory and residential birds, salmon, forage fish, other wildlife and their primary feeding areas, and a recommendation by the National Marine Fisheries Service that “an alternative site be identified in a location that results in less potential impacts to wildlife that is more appropriate for aquaculture and meets the goals of the tribe,” permitting agencies approved permits and a lease for a 50-acre industrial oyster farm for private financial gain inside the Dungeness National Wildlife Refuge. This decision, which is in violation of the Clean Water Act and the Migratory Bird Treaty Act, must be reversed. Agencies are well aware of the potential damage to the lands it is their mission to protect. Tell the Washington State Department of Natural Resources and the U.S. Fish and Wildlife Service that the Dungeness National Wildlife lease must be rescinded.  The Dungeness Bay Wildlife Refuge was created by Executive Order in 1915 by Woodrow Wilson, directing the area to be set aside as a “refuge, preserve and breeding ground for native birds and prohibits any disturbance of the birds within the reserve.” The Refuge provides habitat, a preserve and breeding grounds […]
