(Beyond Pesticides, September 13, 2024) While chemical companies persist in pushing simplistic solutions to complex problems, there is a large amount of evidence that organic farming presents effective solutions to many of those problems. Now there is new evidence that organic agriculture prevents the untold harms of pesticide-driven monoculture. In a new study, German researchers compared 16 agricultural landscapes in Lower Saxony and northern Hesse that had different combinations of semi-natural habitat, organic practices, and annual and perennial flower strips. Overall, the researchers find that organic farming provides the highest benefit to the bees, along with the presence of diverse flowering plants in and near monoculture fields. The study compares the effects of three honey bee conservation methods on the prevalence of the parasitic mite Varroa destructor and the 11 parasites Varroa transfers to bees, and the impact of these destructive organisms on bee colony growth. The findings were reported in the June issue of the Journal of Applied Ecology. Organic practices lead directly to lower parasite load and higher colony growth—essentially, the more organic crops, the more bees, and the more parasites, the fewer bees. Pesticides plus monoculture doubles the damage: Pesticides increase mortality, damage bees’ immune systems, and […]

(Beyond Pesticides, July 3, 2024) In June, the Vermont legislature officially passed H.706 into law – a bill that narrows and reduces the use of neonicotinoid insecticides and neonicotinoid-treated seeds. The legislature came together to override a veto of the bill issued by Governor Phil Scott (R). Gov. Scott said the bill’s language had “the potential to produce severe unintended environmental and economic consequences–—particularly for Vermont’s dairy farmers.” The advocacy in support of the legislation called for a holistic, systems change approach to legislative priorities that considers economic, ecological, public health, and climate resilience. The Vermont legislation builds on New York legislation, which in turn is inspired by Quebec’s “verification of need” prescription model (a.k.a. emergency exemptions) that has proven to dramatically reduce the use of certain neonicotinoids, yet enables the continued use of toxic pesticides and a legacy of pesticide dependency in land management and crop production. Vermont Bill Building on New York The Vermont Bill (See pages 29 to 44 for final text) mirrors the language of New York’s Birds and Bees Protection Act (S. 1856-A and A. 7640) and adopts New York’s language on timing regarding when critical sections go into effect. The Vermont language contains trigger language that […]

(Beyond Pesticides, June 21, 2024) A recent review of the scientific literature, published in Science of The Total Environment, analyzes multiple species of bees on a molecular level to better understand the poisoning mechanisms that could, as the authors see it, inform chemical risk assessments with more precision. The mechanisms “implicated in the tolerance of bees to specific pesticides, and thus as determinants of insecticide sensitivity, … include metabolic detoxification, insecticide target proteins, the insect cuticle and bee gut microbiota,” the authors write. This review references more than 90 studies performed over the last 30+ years, with most being published in the last 5-10 years, as the understanding and importance of molecular determinants of bee sensitivity has emerged. Pollinators, such as bees, provide crucial ecosystem services by pollinating both wild plants and essential crops. The exposure these insects are subjected to threatens their existence, which occurs through pesticide contamination that can lead to impacts on growth and development or even colony collapse.    “While bees have only been exposed to human-made pesticides over the recent past (last 80 years) they have co-evolved with plants and fungi which produce a range of xenobiotics, including plant allelochemicals and mycotoxins,” the authors state. […]

(Beyond Pesticides, June 14, 2024) The influence of the chemical industry over public policy and regulation, especially in agriculture, is glaringly obvious and has little popular support, yet no one can seem to do anything about it. Numerous analyses have detailed the ways this influence is applied—through lobbying and political donations including dark money; industry experts named to regulatory agency scientific advisory boards; and the massive public relations machines that create and sustain public uncertainty using the tobacco industry playbook revealed by Naomi Oreskes and Erik Conway in their 2010 book Merchants of Doubt. A more insidious tendril of industry influence is explained in U.S. Right to Know’s (USRTK) report, released this month, on pesticide manufacturers’ infiltration of the Entomological Society of America (ESA). The report, “Anatomy of a science meeting: How controversial pesticide research all but vanished from a major conference,” examines the ESA’s 2023 annual meeting—its program, sponsorships, presentations, panelists, poster sessions, meet-and-greets, budget, revenue sources, and other aspects of the event. What is revealed is a systematic and comprehensive industry presence throughout the society and its meeting. A direct consequence is the near-elimination of any scientific presentations addressing the effects of neonicotinoid pesticides on insects, particularly bees. […]

(Beyond Pesticides, September 26, 2023) In Ethiopia’s Bahir Dar, where Lake Tana feeds into the Blue Nile, a major hydroelectric power plant stands, serving as an emblem of the ecosystem services the river provides to over two million inhabitants. Yet ever since its first appearance in 2012, this crucial waterway has been under attack by one of the world’s most invasive species: the water hyacinth.   In America and Europe, where agrochemical giants such as Bayer and Syngenta are headquartered, such problems might quickly be remedied using herbicides. However, the prevailing ethos coming from the African continent is quite different. Dion Mostert, whose South African boat business has suffered due to the water hyacinths infestation, encapsulates this sentiment, saying he has considered herbicides but sees them as a temporary fix to a much larger challenge.  Instead of relying on temporary—and often harmful—agrochemical solutions, Ethiopia and other African countries are embracing holistic and sustainable solutions.   For instance, Lake Victoria–a water body shared by Kenya, Tanzania, and Uganda—suffered from a water hyacinth infestation in the 1990s. In response, scientists introduced two species of weevils known to be natural predators of the hyacinth: Neochetina bruchi and Neochetina eichhorniae. The initiative was extremely successful, […]

(Beyond Pesticides, August 30, 2023) Invasive yellow-legged hornets have been spotted near Savannah, Georgia, causing concern among agriculture officials. These hornets are known for their ability to prey on honeybees and other pollinators, and their presence in the United States is a cause for alarm. This is the first time a live specimen of this species has been detected in the open United States, according to the Georgia Department of Agriculture. The hornets, which are native to Southeast Asia, have been spotted in other parts of the world, including Europe, where they have caused significant damage to bee populations. They are considered “invasive,” which means the hornet is not native and officials expect their introduction to result in economic, environmental, or health-related damage to humans, animals, plants, or the environment. In response to the sighting in Georgia, officials are taking action to eradicate the hornets before they can cause any harm to US agriculture. One of the methods being used to eradicate the hornets is the localized use of the highly toxic insecticide cypermethrin on nests. The pesticide has been registered for use in agriculture and residential pest control since the 1970s. It kills insects such as mosquitoes, flies, ticks, […]

(Beyond Pesticides, August 29, 2023) A study published in Insect Biochemistry and Molecular Biology finds the widely used azole fungicide, tebuconazole, has damaging impacts on the redox homeostasis (the process of maintaining balance between oxidizing and reducing reactions) and fatty acid composition in honey bees’ brain via oxidative stress. Acute, field-realistic sublethal exposure to tebuconazole decreased the brain’s antioxidant capacity, key antioxidant defense systems, and oxidative degradation and alteration of lipids (fats) in the brain. Thus, this study adds to the scientific literature on the adverse effects of chemical exposure on pollinator health, especially in sublethal concentrations. Degenerating cognitive skills can threaten honey bee survivability, decreasing 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. Pollinator declines directly affect 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, depress crop yields. In turn, the economy will take a hit, since much of the economy (65%) depends upon the […]

(Beyond Pesticides, July 21, 2023) A comprehensive and scathing report, “Neonicotinoid insecticides: Failing to come to grips with a predictable environmental disaster,” issued by American Bird Conservancy (ABC)in June, lays out the dire consequences of neonicotinoid (neonic) pesticides’ continued use. The report is an update of an earlier review from 2013, which warned of the risks to birds, stating starkly: “A single corn kernel coated with a neonicotinoid can kill a songbird. Even a tiny grain of wheat or canola treated with the oldest neonicotinoid, imidacloprid, can poison a bird. As little as 1/10th of a corn seed per day during egg-laying season is all that is needed to affect reproduction with any of the neonicotinoids registered to date.” The story of neonic harm is one that has been repeated for generations with different pesticides. Pesticide manufacturers claim every new generation of their products is safer and more environmentally benign than the previous one. This is seldom true. There is ample evidence that pesticides pose threats to nearly every class of organism on Earth, from earthworms to elephants. The neonicotinoids, introduced in the early 1990s, have been marketed as safe for vertebrates, non-bioaccumulative, and, because of their flexible application methods […]

(Beyond Pesticides, April 20, 2023) This Earth Day (Saturday, April 22, 2023), Beyond Pesticides urges individuals to spread awareness of the toxic pesticides that poison people and the environment and the safe alternatives that are available to safeguard communities and the surrounding environment. On Earth Day, reflecting on the beauty and wonder of the natural world highlights the importance of restoration and preservation to maintain the planet’s intricate web of life. However, the natural world on which life depends is under dire threat as the dependence on toxic chemicals (e.g., pesticides) enables ongoing environmental contamination. Mechanized and industrial human activity perpetuates ongoing toxic chemical contamination, resulting in massive die-offs of beneficial organisms, increased rates of autoimmune diseases, endocrine disrupting and transgenerational chemical effects, and widespread pollution of our air and waterways. Beyond Pesticides, has the tools needed to increase environmental awareness in your community. Therefore, this Earth Day, Beyond Pesticides continues to advocate for the adoption of organic practices and policies that alleviate threats to ecosystems and enhance biodiversity. Michigan State University professor Thomas Dietz, Ph.D. highlights, “Continuing the successes of environmentalism—an integration of science, a concern with human well-being and justice, and a recognition of the need to consider […]

(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, 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, 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, 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, January 28, 2022) Do city dwellers, who typically have smaller-sized greenspaces on their lots, have any role to play in supporting pollinators? Absolutely, according to a recent study of Bristol, England residential gardens. The researchers find that the amount of “floral resource” — the abundance of actual blooms, which translates roughly to amount of nectar production — varies widely across gardens and yards, and that small urban gardens and greenspaces are actually some of the most pollinator-friendly resources. The study notes that that several factors influence how well these resources provide food for pollinators, most important among which are pollinator-friendly management practices. Beyond Pesticides notes that there are multiple resources in the U.S. on making gardens and greenspaces “friendly” and useful to pollinators, including its own BEE Protective guidance on garden and landscape management, and that employing organic management practices is critical. The researchers hope to “develop evidence-based management recommendations to support pollinator conservation in towns and cities.” Their paper, published in the Journal of Applied Ecology, reports that the size of the Bristol gardens they studied actually had minimal relationship to the amount of nectar produced by the plants in them. There are factors beyond size that determine the […]

(Beyond Pesticides, December 10, 2021) In a win for pollinators, a California Superior Court has issued a ruling that sulfoxaflor, a systemic pesticide that is “field legal” but “bee lethal,” can no longer be used in the state. The suit was brought by the Pollinator Stewardship Council and the American Beekeeping Federation. The ruling of the Superior Court of the State of California for Alameda County finds that the argument of the petitioners — that sulfoxaflor approval decisions by the California Department of Pesticide Regulation (DPR) violated the California Environmental Quality Act (CEQA) — is valid. Eliminating this highly bee-toxic pesticide from use in the state is expected to protect not only native bees and other pollinators (including Monarch butterflies in early Spring), but also, the many millions of managed-colony bees that are transported to California for pollination of almond and other crops. The suit was filed against DPR, Corteva inc., Dow Agrosciences LLC, the Siskiyou County Department of Agriculture, and James E. Smith as Siskiyou County Agricultural Commissioner. Having found for the petitioners’ request for a Writ of Mandate (a court order requiring a lower court or public authority to perform its statutory duty), the court instructed the petitioners to […]

Read on as we consider the range of challenges we must confront, and the solutions that can bring us all together. The Climate As climate impacts grow, an increase in uses of synthetic pesticides in agriculture is likely — because of waning efficacy (pesticide resistance) of these compounds, and mounting pest pressure (i.e., increasing insect population and metabolism). Production of pesticides contributes to greenhouse gas emissions gas (e.g., nitrous […]

(Beyond Pesticides, November 19, 2021) Thanksgiving offers an opportunity for people to come together and give thanks for the bounty of an organic harvest. Unfortunately, many Thanksgiving meals are produced by chemical farming practices that utilize hazardous pesticides, genetically engineered (GE) crops, and petroleum-based synthetic fertilizers. These inputs, apart from being unnecessary, degrade ecosystems and affect the health of consumers and agricultural workers alike. It’s never too late to start a new tradition – for this year and into the future, make your Thanksgiving feast sustainable by going organic. Now, more than ever, it’s important to go organic: For Our Own Health Going organic drastically reduces the amount of pesticide in a person’s body. Although Thanksgiving is generally no time to think about dieting, we’ll aim to make it instructive: recent research finds that one of the biggest health benefits of the Mediterranean Diet comes when you go organic. Compared to individuals on a Mediterranean diet filled with chemically farmed foods, those that ate organic had 91% lower pesticide residue. This finding is backed up by a considerable body of prior research. A 2015 study based on self-reported food intake found that those who eat organic generally have much lower […]

(Beyond Pesticides, August 23, 2021) “Biopesticides”—widely regarded as an alternative to chemical pesticides and hence given a special status in regulation—need a better definition. “Biopesticide” is generally poorly understood, and defined differently by various entities and stakeholders. The term can be misleading and mixes contradictory approaches. It is troublesome when we continue to look for product replacements or substitutions for agricultural practices that are clearly ineffective, and in the process avoid the changes necessary to transition to organic practices, which represent the real, long-term solution to concerns among chemical-intensive farmers that they are losing pesticides in their arsenal, either to organism resistance or regulatory restrictions. The U.S. Environmental Protection Agency (EPA) uses the following definition for “biopesticides”: Substances that interfere with mating, such as insect sex pheromones, as well as various scented plant extracts that attract insect pests to traps (and synthetic analogs of such biochemicals); Microbial pesticides consisting of a microorganism (e.g., a bacterium, fungus, virus or protozoan) as the active ingredient; Plant-Incorporated-Protectants (PIPs), pesticidal substances that plants are genetically engineered to produce. Tell EPA it’s time to redefine “biopesticide.” It is deceptive and misleading. The definition should not include genetically modified organisms or synthetic analogs of naturally occurring […]

(Beyond Pesticides, May 14, 2021) In a prime example of cart-before-the-horse, greenwashing, or perhaps “beewashing,” a British company has badly missed the mark in its latest attempt to market a product while “doing good” and generating goodwill with customers. As The Guardian reports, Marks & Spencer, the giant United Kingdom (UK) retailer, is releasing 30 million managed honey bees into rural British landscapes in what the company is promoting as an effort to support biodiversity and the beekeeping sector. However, according to experts and environmental advocates, unleashing that many honey bees may well actually harm both wild native bees and honey bees themselves. Critics of the move say this means that wild bees will likely face fiercer competition for already inadequate food sources. Beyond Pesticides adds that these honey bees have been dispatched to the same pesticide-contaminated habitats in which existing bee populations of all kinds face harmful exposures — exacerbating issues surrounding pollinator decline rather than solving them. Marks & Spencer’s Twitter marketing promotes the project in this way: “Did you know that bees contribute to a third of the food we eat? At M&S, we’re introducing more than 30 million bees to our Select Farms to help protect the […]

(Beyond Pesticides, May 7, 2021) Soil health is one of the linchpins on which the food production that sustains human life — as well as biodiversity, pollinator health, and carbon sequestration — depend. A recent meta-review of nearly 400 studies finds that, in 71% of the cases reviewed, pesticides kill or otherwise harm soil invertebrates that contribute mightily to soil health. In their paper, “Pesticides and Soil Invertebrates: A Hazard Assessment,” published in Frontiers in Environmental Science in early May, the researchers write, “A wide variety of soil-dwelling invertebrates display sensitivity to pesticides of all types . . . [These results] support the need for pesticide regulatory agencies to account for the risks that pesticides pose to soil invertebrates and soil ecosystems.” Beyond Pesticides, which has long reported on impacts of pesticides on soil health, concurs with that conclusion, and adds that the real solutions to noxious pesticide impacts lie in the adoption of  regenerative organic approaches to all land management because they obviate any need for petroleum-based toxic chemical controls. The term “pesticide” can refer to myriad kinds of chemical treatments — including antimicrobials, disinfectants, rodenticides, and others — but in the agricultural and land management realms, primarily means insecticides, […]

(Beyond Pesticides, April 13, 2021) A new study is making it increasingly clear that current laws are not protecting wild, ground nesting bees from the hazards of neonicotinoid insecticides. According to research conducted under a grant from the U.S. Department of Agriculture’s Sustainable Agriculture Research and Education (SARE) projects, Blue Orchard Mason Bees (Osima spp) are at particular risk from pesticide-contaminated soil they use to create their nest. Authors of the study note that with honey bees already in decline, pollination services provided wild managed bees like Mason bees are growing in importance. “Wild bees such as Osmia are becoming increasingly popular as managed pollinators in many systems, as there is growing concern that honeybees may not be able to continue to meet the increasing demands of agricultural pollination if these trends continue,” the study reads. The study looked at three overarching threats to mason bee populations, aiming to identify risks from pesticide contaminated soil used as a nest, effects on larvae exposed to contaminated soil, and whether female mason bees could determine the difference between contaminated and uncontaminated soil. “Imidacloprid is a neonicotinoid, which is a group of pesticides that are highly toxic to bees,” said Christine Fortuin, PhD, […]

(Beyond Pesticides, March 3, 2021) Earlier this week, pesticide regulators in the commonwealth of Massachusetts voted to restrict outdoor consumer uses of neonicotinoid insecticides. The move is the result of sustained advocacy from broad coalition of individuals and organizations focused on protecting pollinators and ecosystem health. While advocates are pleased that the Pesticide Board Subcommittee made Massachusetts the first state in the country to restrict neonicotinoids through a regulatory process, they note this is only the first step in eliminating these hazardous insecticides. “This marks an incremental victory which took us 6 years to land, and it only happened because of immense, ongoing grassroots action and legislative allies who are willing to hold state regulators accountable,” said Martin Dagoberto, Policy Director of the Northeast Organic Farming Association, Mass. Chapter in a press release. “We still have a monumental endeavor ahead if we are to reduce toxins and rein in the toxic influence of the chemical lobby,” Mr. Dagoberto added. Advocates had been pushing the legislature to pass An Act to protect Massachusetts Pollinators, sponsored by pollinator champion Representative Carolyn Dykema, since 2014. Following several failures by state lawmakers to bring the bill over the finish line, efforts in 2019 resulted […]
