(Beyond Pesticides, October 20, 2023) Comments are due October 22. This action requires use of Regulations.gov. See instructions and proposed comment language that can be copy and pasted by clicking HERE. The U.S. Environmental Protection Agency’s (EPA) plan to “protect” endangered species, its Draft Herbicide Strategy Framework, continues a legacy of failed risk assessment and mitigation measures that do not meet the moment of looming biodiversity collapse. This is a critical time for the agency to embrace real fundamental change in how it regulates pesticides, recognizing that land management strategies, including in agriculture, exist that are no longer reliant on pesticides. This is not a time to tinker with strategies that EPA admits fall short. Recognizing that its Pesticide Program has failed to meet its obligation to protect endangered species from registered pesticides, EPA has come up with a strategy to redefine its responsibilities to protect endangered species in its pesticide registration and registration review program. According to EPA, “The proposed Strategy is structured to provide flexibility to growers to choose mitigations that work best for their situation. Additionally, the draft Strategy may require more or less mitigation for growers/pesticide applicators depending on their location.” Understandably, EPA has taken this approach, […]

(Beyond Pesticides, October 3, 2023) On September 19, 2023, Chicago Mayor Brandon Johnson and Corporation Counsel Mary B. Richardson-Lowry took legal action against agrochemical giant, Monsanto, filing a lawsuit that alleges the corporation’s role in polluting Chicago with Polychlorinated biphenyls (PCBs) decades ago, despite knowing the chemicals’ detrimental effects.   PCBs are identified as “forever chemicals” due to their environmental persistence. According to the Environmental Protection Agency (EPA), these chemicals “do not readily break down once in the environment.” They cycle through air, soil, and water and can travel long distances, with PCBs found worldwide.  They pose serious health risks as they can accumulate in the environment and within organisms including plants, food crops, sea life, and humans. Those who consume fish from contaminated waterways are exposed to PCBs as the chemical bioaccumulates in the fish population.  PCBs are man-made organic chemicals composed of carbon, hydrogen, and chlorine atoms. They were first manufactured and sold in 1929 by the Swann Chemical Corporation and subsequently came under the ownership of Monsanto Chemical Company in 1935. Due to their non-flammability, stability, and electrical insulating properties, PCBs quickly found widespread use. Their applications included use in electrical equipment, paints, plastics, and carbonless copy […]

(Beyond Pesticides, September 29, 2023) In unsurprising news, the Environmental Protection Agency (EPA) has reversed itself and decided not to ban a dangerous pesticide: tetrachlorovenphos (TCVP) used in pet flea collars and other flea products. This is despite its own earlier decision to ban TCVP in pet collars and scathing criticism of its methods and conclusions by the courts. First registered in 1966, TCVP belongs to the notoriously toxic organophosphate chemical family and is classified by the World Health Organization as “possibly carcinogenic to humans.” It was originally registered to Shell Chemical, then to E.I. duPont de Nemours, then to Hartz Mountain Corporation and Fermenta Animal Health Company.  Early on, it was registered for use on food crops and livestock, but the crop uses were voluntarily de-registered in 1987. It is still widely used on pets and farm animals. In 1995, EPA issued the opinion that “all uses of tetrachlorvinphos, with the exception of oral feed-through larvicide treatment to livestock intended for food use, will not cause unreasonable risk to humans or the environment.” Since then, the agency has contorted itself repeatedly to allow TCVP to remain on the market. There is little research available on TCVP’s human health effects; the […]

(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, September 19, 2023) Farmworkers in Paarl, South Africa took to the streets on Friday, September 8, demanding an end to the indiscriminate importation and use of pesticides, herbicides, and fungicides containing substances prohibited by the European Union (EU). This protest is part of a broader global trend of outcry against systemic issues of environmental racism that disproportionately burden communities with environmental and health risks.   Organized by the Women on Farms Project, the protesters marched to the headquarters of Bayer. The German pharmaceutical, biotechnology, and pesticide company, responsible for producing and exporting agrochemicals known to be toxic to ecosystem and human health, has previously faced multiple lawsuits, including a multimillion-dollar one linking their glyphosate weed killer products (Roundup®) to non-Hodgkin Lymphoma. At the Bayer office, the protesters presented a memorandum demanding an end to the importation and use of EU-prohibited substances.    Protesters sought to expose the hypocritical tactics European agrochemical companies use to sell products in developing nations, even when those products are deemed unsafe in their home countries. Numerous farmworkers, like victim-turned-activist Antie Dina, spoke out about their health issues from petrochemical exposure. In her talk, Dina emphasizes that, “… enough is enough, we do not want any […]

(Beyond Pesticides, September 18, 2023) Advocates for organic have consistently maintained that public engagement with the National Organic Standards Board (NOSB) is critical to protecting the values and principles embedded in the Organic Foods Production Act (OFPA). While the NOSB is a stakeholder board that reflects the sectors of the organic community—from consumers, farmers, processors, certifiers, retailers, and scientists—public interaction with the board offers critical input to the NOSB’s decision-making process. Ultimately, Board authority over the National List of Allowed and Prohibited Substances and its advisor relationship to the U.S. Secretary of Agriculture have a direct effect on the underlying decisions that determine the credibility of the U.S. Department of Agriculture (USDA) organic label that is now widely found on products in virtually all grocery stores. A major issue that continues to plague label integrity is the Board’s review of so-called “inert” ingredients in materials allowed in organic. These are potentially toxic ingredients that should be reviewed by the Board, substances not disclosed on labels of products that may be used in organic production or processing. The NOSB has access to the complete list of “inerts” used in organic materials, and advocates are urging the Board to begin immediately its […]

(Beyond Pesticides, September 15, 2023) The U.S. Environmental Protection Agency suspended the registration of the herbicide dimethyl tetrachloroterephthalate (DCPA) (also widely known as Dacthal), effective August 22, 2023 and leaves existing stocks (products containing DCPA manufactured before August 22) available on the market. The decision is one of a series of EPA attempts dating to 2013 to get more data from the manufacturer as the agency considers reregistration of DCPA. The suspension is toothless, however, since EPA did not totally close the book on this chemical. Six days before the suspension, EPA signed a settlement agreement with the sole manufacturer, AMVAC Corporation, to reinstate the registration upon receipt of the complete toxicological data—that is, animal and laboratory tests— needed to determine the chemical’s safety and how and where it can be used. DCPA is currently classified by EPA as a possible human carcinogen and has also been shown to be a thyroid hormone disrupter. DCPA is regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Pesticides are supposed to undergo reregistration every 15 years to take new science into consideration, but this process is glacial. Congress amended FIFRA in 1988 to speed up reregistration of products registered before 1984, and […]

(Beyond Pesticides, September 14, 2023) As we celebrate National Organic Month this September, it is the perfect time to reflect on why you should consider going organic. Do you try to buy organic food when you can? Are you looking for a way to reduce your and your family’s exposure to toxic pesticides? The benefits of choosing an organic lifestyle extend far beyond your diet or your own health. Beyond Pesticides is helping communities transition parks and public lands to organic land management.

(Beyond Pesticides, September 13, 2023) A study published in Global Change Biology finds climate change increases bees’ sensitivity to pesticide exposure, impairing the pollinators’ ability to respond to light (Ultra-Violet [UV] stimuli), reducing floral syrup consumption, and lessening longevity (length of life) up to 70 percent. Notably, the reduction in floral syrup consumption indicates nutritional stress that further impacts bee species’ fecundity (productiveness), driving bee declines. Unless more is done to combat the climate crisis, the current global warming scenario increasing bees’ sensitivity to pesticide exposure will continue to threaten all pollinator health. The pervasiveness of pesticide exposure, combined with climate change, threatens global species biodiversity. As has been widely reported, pollinators (such as bees, monarch butterflies, and bats) are a bellwether for environmental stress as individuals and as colonies. Pesticides intensify pollinators’ vulnerability to health risks (such as pathogens and parasites), with pesticide-contaminated conditions limiting colony productivity, growth, and survival. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one million species of plants and animals at risk, including pollinators. Pollinator declines directly affect the environment, society, and the economy. Without pollinators, many agricultural and nonagricultural plant species will decline or cease to exist as U.S. pollinator declines, particularly […]

(Beyond Pesticides, September 8, 2023) In a united effort, climate and environmental justice movements from around the world have come together to announce a global “end to fossil fuels,” including the end of pesticides. The “March to End Fossil Fuels” is scheduled for September 17 and the Secretary General’s Summit in New York City on September 20. See the full map for other marches around the world. At the Beyond Pesticides, 2022 National Forum session on climate (November, 2022), we discussed the science and the urgent need for a strategic response to the climate crisis as part of a constellation of crises that intersect. Whether we are talking about a health crisis borne out of chemical-induced diseases, the collapse of life-sustaining biodiversity, or the dramatic catastrophes caused by greenhouse gases and rising temperatures—the interconnectedness of the crises requires strategic solutions that are holistic and nurturing of our relationship with nature —a relationship we have minimized as a matter of policy and practice. The data on climate calls on us to be audacious in our demand for urgent change in our households and communities, and from decision makers at all levels of government. At Beyond Pesticides, our audacious goal is to […]

(Beyond Pesticides, September 7, 2023) During Organic Month, the importance of organic practices is brought into sharp focus by a study published in July in Environmental Health Perspectives, which emphasizes the importance of an organic diet and location to residues of pesticides in the body. The study finds urinary levels of the weed killer glyphosate significantly decrease through an organic diet for pregnant individuals living further than 0.5km (~1640ft) from an agricultural field. However, the study finds that adopting an organic diet among pregnant individuals living closer than 0.5km to an agricultural area does not significantly decrease glyphosate levels, indicating alternative sources of contamination outside of diet. Although past studies prove time and time again that an organic diet can reduce the levels of pesticides in the body, far too few studies investigate how the intervention of the organic diet can alter glyphosate levels among pregnant individuals living near or far from agricultural fields on which the herbicide is used. Furthermore, pesticides’ presence in the body affects human health, especially during vulnerable life stages like childhood, puberty, pregnancy, and old age. The study raises the complexity of fully tracking multiple exposures to glyphosate and other pesticides and the need for […]

(Beyond Pesticides, August 31, 2023) A study published in Environmental Research finds glyphosate levels in the body adversely affect neurological health. Specifically, oral intake (e.g., eating contaminated foods), inhalation, and dermal exposure to glyphosate lowered cognitive function scores, heightened likelihood of severe depressive symptoms, and impaired auditory (hearing) function. Thus, this study provides some of the first evidence linking glyphosate exposure to specific neurological health outcomes among the general U.S. population, indicating the need for further studies on mechanisms driving neurotoxicity and the medical significance over time. Although this study is among the first to highlight specific neurological effects from glyphosate exposure among the general population, this study is not the first to identify potential neurotoxicity from glyphosate exposure. (Previous research cited below.) The ubiquity of glyphosate uses in agriculture—which leaves residues of the toxic chemical in food—and in public areas (e.g., parks, and walkways) may mean that exposures to it represent a significant risk factor for the disease. Glyphosate is already implicated or proven in developing numerous health anomalies, including cancer. The neurological system, including the brain, spinal cord, and a vast network of nerves and neurons, is responsible for many bodily functions—from sensation to movement. However, pesticides play various roles in […]

(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, August 28, 2023) As the need to eliminate petrochemical fertilizers looms large in the context of existing existential crises relating to health threats, biodiversity collapse, and the climate emergency, the leadership of the U.S. Environmental Protection Agency (EPA) is under increasing public scrutiny. One program that is being closely watched is the agency’s Safer Choice product labeling program which could, according to advocates, be strategic in differentiating in the marketplace those products that are not contributing to the climate crisis, biodiversity collapse, and dramatic health effects. Beyond Pesticides is advocating, in response to a request for public comment from EPA (due September 11, 2023), that EPA (under its Safer Choice program) evaluate fertilizers for compatibility with natural systems, protection of soil organisms, waterways, human health, and helping to mitigate the climate and biodiversity crises. With the Safer Choice label, consumers—from farmers, landscapers, to gardeners—could determine at the point of sale which fertilizer products are not contributing to the floods, fires, and loss of life associated with the climate crisis. Beyond Pesticides previously initiated an action urging that EPA’s Safer Choice program be more holistic and in sync with natural systems, not just a product substitution program. This week, Beyond […]

(Beyond Pesticides, August 14, 2023) Marijuana regulators in the state of Washington issued administrative holds on 18 licenses due to pesticide-contaminated marijuana, forcing producers and processors to cease operations until now. This shutdown of legal marijuana businesses serves as a window into a broader historical backdrop of pesticide issues within the marijuana industry. Within Washington, pesticide concerns have been growing since a study in 2018 of legal marijuana farms in the state had 84.6% (of 26 samples) with significant quantities of pesticides including insecticides, fungicides, miticides, and herbicides. Last year, a national study identified a list of contaminants in 36 states and the District of Columbia and found 551 pesticides within cannabis products. For over a decade, Beyond Pesticides has sounded the alarm about the highly-concentrated levels of pesticides in marijuana products, calling on state officials to require organic marijuana, especially in the context of medical marijuana. The absence of federal regulations for pesticides in cannabis production has raised significant concerns about exposure risks for recreational and medicinal use, exposure risks to workers, and potential environmental contamination impacting wildlife. Since marijuana is classified as a Schedule 1 narcotic under the Controlled Substances Act, the EPA does not regulate pesticides in […]

(Beyond Pesticides, August 11, 2023) Reinforcing earlier findings, a systematic review published in Chemosphere finds the popular herbicide glyphosate and its formulations (glyphosate-based formulations-GBF) exhibit five out of the ten key characteristics (KC) of carcinogens (cancer-causing chemicals). Specifically, glyphosate exhibits strong evidence of genotoxicity, epigenetic alterations (heritable changes in gene expression), oxidative stress, chronic inflammation, endocrine disruption, and disturbs gut microbiota implicated in lymphomagenesis (growth and development of lymphoma). Although organizations like the International Agency for Research on Cancer (IARC) designate glyphosate as a probable human carcinogen, and scientific literature supports the findings on these adverse effects purported by glyphosate, the chemical remains on the U.S. market in various formulations. Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, not just Bayer’s (formerly Monsanto) Roundup®. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in food and water commodities. In addition to this study, literature proves time and time again that glyphosate has an association with cancer development, as well as human, biotic, and ecosystem harm. Therefore, advocates point to the need for national policies to reassess hazards associated with […]

(Beyond Pesticides, August 4, 2023) The results of an Australian study published in Nature strike a contrast between land and water contamination with pesticide active substances (PAS), highlighting contamination as pesticides are transported through waterways.  The study results on water transport raise serious contamination issues. Only about one percent of the pesticides entering rivers degrade, so that long stretches of waterways and the oceans suffer the direct impact of a pesticide’s active ingredient. The lack of degradation also means that water organisms are being exposed to levels of pesticides exceeding many of the regulatory threshold limits set by governments. Although observation data are highly variable, the authors note that measured concentrations of pesticides in some river reaches of North America, East Asia and Europe exceed one or more regulatory threshold limits “at least once a year.” Further, the pesticides can bioaccumulate at each level of the aquatic food web, which can multiply concentrations by a thousand or more in the highest trophic levels, according to the study authors. The study finds that more than four-fifths of PAS are degraded in the soil, leaving about 10 percent of the original chemical in the soil as residue. Nearly half of that residues […]

It’s hard to escape the impacts of the Barbie movie’s estimated $150 million marketing campaign. You may have noticed advertisements with Burger King’s pink burgers to Airbnb’s Barbie Dreamhouse. Perhaps you have seen viral memes or news stories about the movie’s takedown of the patriarchy or critiques that the movie is overly woke. The pink symbol of Barbie is often followed by a second symbol — plastic. The total mass of plastics on Earth now doubles the total mass of all living mammals, so would Barbie say life is fantastic? Or, might she urge the National Organic Standards Board to ban plastic mulch, an issue on the agenda at the Board’s upcoming October meeting? Plastic products, including those used in chemical-intensive and organic agriculture, and pesticides, play a seemingly necessary role in modern life, encompassing many items beyond straws and grocery bags. However, the convenience of plastic comes at a considerable cost to the planet and human health. The majority of plastics are manufactured using oil and gas, exacerbating climate change. Scientists are becoming increasingly alarmed by the repercussions of microplastics, which are plastic particles smaller than 5 mm in size. In 2022, Philip Landrigan, M.D., et al., announced the […]

(Beyond Pesticides, July 28, 2023) A study published in Science of the Total Environment finds glyphosate can adversely impact sensory and cognitive processes in bumblebees (Bombus terrestris). Glyphosate exposure impairs bees’ learning of aversive stimuli like electric shocks paired with specific color discrimination. Additionally, the pesticide reduces attraction to UV (ultraviolet) light, specifically the color blue, and temporarily impacts locomotion and phototaxis (movement in response to light). These impairments to sensory and cognitive processes render foraging difficult for these glyphosate-exposed pollinators and vulnerable to unavoidable predators. The study highlights that symptoms of widespread chemical exposure may reduce foraging efficiency and adversely affect ecosystems, especially those dependent on insect pollinators.  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, limit crop yields. In turn, the economy will take a hit, since much of the economy (65%) depends upon the strength of the agricultural sector. As the science shows, pesticides are one of the most significant stressors for pollinators. In a world where habitat loss and fragmentation show no sign of abating, scientists have concluded that the globe cannot afford to continue […]

(Beyond Pesticides, July 27, 2023) A study published in the Journal of Economic Entomology calls into question the scientific literature on protecting bees from pesticides. The study analyzes actions taken by pesticide users to reduce the risk of pesticides on nontarget organisms, known as “mitigation measures.” Ultimately, the study finds that there is insufficient evidence to support the effectiveness of bee-protecting mitigation measures.    “Almost all research was centered around protecting honey bees. However, honey bees are a managed species that is not endangered,” Edward Straw, Ph.D., a postdoctoral researcher in the School of Agriculture and Food Science at University College Dublin in Ireland and lead author on the study, says, “When we try to protect bees, we really want to be protecting wild, unmanaged bee species, as these are the species which are in decline.”  The study includes a chart of mitigation methods that have been tested in the scientific literature. The mitigation measures under evaluation include: restricting pesticide application to certain times of day, restricting the application of pesticides during weather events, removing flowering weeds that attract pollinators, applying repellents to deter pollinators, and more. The researchers find that there are few empirical tests on the most widely used […]

(Beyond Pesticides, July 24, 2023) Sewage sludge, also known as biosolids, is a byproduct of sewage treatment and is used as a source of organic matter for amending soil in nonorganic agriculture and landscaping. EPA has published a list of 726 chemicals found in biosolids in the National Sewage Sludge Surveys. This list does not include the per- and polyfluoroalkyl substances (PFAS), which are emerging contaminants of biosolids. Tell your Governor and local officials to ban the use of biosolids in farms and parks, until there is adequate testing of toxic residues—which does not currently exist. In addition to PFAS (also referred to as “forever chemicals”), persistent toxic pollutants found in biosolids include: inorganic chemicals such as metals and trace elements; organic chemicals such as polychlorinated biphenyls or PCBs, dioxins, pharmaceuticals, and surfactants; and pathogens including bacteria, viruses, and parasites. Regulation of biosolids by the U.S. Environmental Protection Agency (EPA) has been found by the EPA Office of Inspector General (OIG), in its report EPA Unable to Assess the Impact of Hundreds of Unregulated Pollutants in Land-Applied Biosolids on Human Health and the Environment, to be inadequate. Lacking sufficient oversight at the federal level, action to protect health and the environment falls […]

(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, June 14, 2023) The exoskeleton of the black soldier fly (BSF; Hermetica illucens) has the potential to be an effective organic fertilizer. A study in the journal Agriculture, Ecosystems & Environment highlights the positive impacts on plant size, flower count, seed production, appeal to pollinators, and resilience to herbivory that the fly’s molted exoskeleton (or exuviae) can have when used as a soil supplement. The use of insect exuviae as an organic alternative to harmful synthetic fertilizers is an important step toward an environment free from chemical contaminants, and BSF are uniquely equipped to contribute to a regenerative organic agricultural system. The study set out to determine the impacts of BSF exuviae on plant growth, resilience to herbivory, and pollination. The scientists divided black mustard plants into four different treatment groups: 1) grown in soil amended with BSF powdered exuviae; 2) control group planted in chemically-treated (conventional) soil; 3) grown in amended soil and subjected to increased herbivory from caterpillars (Pieris brassicae) and aphids (Brevicoryne brassicae); and 4) planted in conventional soil and subjected to increased pest exposure. Scientists measured plant growth, flowering status, seed production, herbivore abundance, and pollinator activity. After three weeks, the supplemented soil grew […]
