(Beyond Pesticides, July 12, 2023) A study by University of Delaware entomologist Thabu Mugala and colleagues finds that modifications to their farming methods can reduce slug damage when those changes also encourage natural slug predators, allowing farmers to avoid the endless cycle of pesticide dependency, pest resistance, genetically engineered crops, and synthetic fertilizers. With insects as the target for tens of millions of pounds of agricultural use, growers of the highest-production crops in the U.S., corn and soybeans, continue to find slugs to be a serious problem. Corn and soybean growers who have adopted no-till or conservation tillage and cover crops often think these practices worsen the problem by increasing moisture and decaying plant material in fields, which slugs love. But the cause-and-effect picture is more nuanced and requires strategies that nurture ecological balance. Slugs are the most damaging non-arthropod pest in no-till corn production in the U.S., and truly effective chemical deterrents do not exist at agricultural scale, as Beyond Pesticides noted here, although biological methods may be on the horizon, such as a parasitic nematode already used in Europe that shows promise. The most voracious natural slug hunters are ground beetles, but harvestmen (daddy longlegs), and wolf spiders […]

(Beyond Pesticides, July 10, 2023) [Editor’s note to readers: The local, democratic decision-making process to adopt restrictions on pesticide use, now under attack in Congress, has historically been critical to the protection of health and the environment when federal and state governments have failed in their responsibility. This local democratic right has not only protected communities where action is taken, but it has driven state and federal policy to do better—to do what is required in a society that cares about a sustainable future. While federal and state pesticide policy sets a floor on minimum protections and rights, there is nothing more important than nurturing the local democratic process to increase and strengthen protections that elude government agencies that are unduly influenced by the powerful chemical industry. As we face existential crises of health threats, biodiversity collapse, and the climate emergency resulting from gridlock in legislative bodies that ignore the scientific facts documenting harm and solutions that are within our grasp, there is nothing more important than empowering local communities to embrace meaningful changes that eliminate pesticides and adopt organic land management practices. These changes embrace nature and ecosystem services. While the federal regulatory process is skewed toward assumptions of […]

The introduction of the Agricultural Labeling Uniformity Act in the U.S. House of Representatives, expected to be a part of the Farm Bill negotiations, is raising the specter (yet again) of undermining local and state authority to protect the health of their residents from pesticides—effectively overturning decades of Supreme Court precedent.

(Beyond Pesticides, July 5, 2023) After nearly 40 years since the Bhopal, India manufacturing facility leaked 47 tons of a chemical used in pesticide production, exposing half a million people and killing thousands, a new study in the BMJ Medical Journal has shed light on the enduring health and human capital effects resulting from in-utero exposure. The study finds significant negative impacts on both economic and health outcomes. Individuals who were in the womb during the disaster exhibited lower birth weights and remain more susceptible to respiratory problems, cognitive impairments, and other health issues later in life. Moreover, those born just after the gas leak were found to have lower educational attainment and reduced earning potential as adults. Over the past four decades, Beyond Pesticides has consistently reported on the Bhopal Gas Disaster, which stands as one of the most devastating industrial tragedies in history [1] [2] [3] [4]. The calamitous night of December 2, 1984, resulted from a gas leak of the highly toxic methyl isocyanate (MIC) from a Union Carbide Corporation (now owned by Dow Chemical Company) manufacturing facility. MIC is an intermediate chemical used in the production of insecticides such as carbaryl (Sevin), aldicarb, and other carbamate […]

(Beyond Pesticides, July 3, 2023) Mosquito season is upon us, and to many that means spraying pesticides to kill them. But not only is spraying flying mosquitoes the most ineffective way to prevent mosquito problems, it is also counterproductive because it eliminates some of our most attractive and helpful allies—birds. Tell EPA to eliminate pesticides that threaten birds or their insect food supply. Tell the U.S. Fish and Wildlife Service and Department of Interior to protect birds by eliminating the use of pesticides that threaten them. Tell Congress that EPA and other agencies need to do their job and protect birds and other mosquito predators. While the appetite of purple martins for mosquitoes is well known, most songbirds eat insects at some stage of their life. Many birds who eat seeds or nectar feed insects to their young, including flying insects that may be bothersome–like mosquitoes or flies. Altogether, birds consume as many as 20 quadrillion individual insects, totaling 400-500 million metric tons, per year. Mosquito-eating birds include many well-known residents of our communities. They include, for example, wood ducks, phoebes and other flycatchers, bluebirds, cardinals, downy woodpeckers, swallows, swifts, robins, orioles, wrens, great tits, warblers, nuthatches, hummingbirds, red-winged blackbirds, […]

(Beyond Pesticides, June 27, 2023) Pesticides interfere with biological processes. This is their purpose. Unfortunately, they nearly always have unintended consequences, many of which have been ignored by their manufacturers. A new review article by Irish and Dutch researchers in the ISME Journal adds to the emerging scientific literature examining how pesticides affect the relationship between the human gut and the human brain (the “gut-brain axis”). Often called the “second brain” because it houses nerve cells and produces neurotransmitters, the gut-brain axis may be the most important locus where microbes and pesticides meet. The human gut plays host to a variety of microorganisms, ranging from bacteria and archaea to fungi, viruses and yeasts.[1] In a healthy person these microbes remain in balance and often cooperate both with each other and with human cells. The gut and the brain are deeply integrated through the vagus nerve and the neuroendocrine system. The vagus nerve is a treelike bundle of fibers extending from the lower part of the brain to nearly every body organ, but particularly the heart, lungs and digestive tract. The neuroendocrine system comprises specialized cells inhabiting nearly all the organs of the body that respond to signals from the brain […]

(Beyond Pesticides, June 26, 2023) In view of EPA’s failure to protect pollinators from pesticides, the lives of those essential insects, birds, and mammals are increasingly dependent on state and local laws that under threat of U.S. Congressional action in the upcoming Farm Bill. Tell Congress: Don’t allow the Farm Bill to preempt state and local laws. The Farm Bill covers many areas—ranging from the supplemental nutritional assistance program (SNAP) to trade—and one provision that the pesticide industry would like to include is preemption of local authority to restrict pesticide use. This attack on local governance  would undercut the local democratic process to protect public health and safety, especially important in the absence of adequate federal protection of the ecosystems that sustain life. As Congress drafts the 2023 Farm Bill, there is an opportunity for many topics—good and bad—to be introduced. Dating back to Franklin D. Roosevelt’s New Deal of the 1930s, which addressed threats posed by the Great Depression and drought, the Farm Bill is an omnibus bill passed every five years. It is designed to secure a sufficient food supply, establish fair food prices for both farmers and consumers, and protect the soil and other natural resources on […]

(Beyond Pesticides, June 20, 2023) Welcome to National Pollinator Week, during which time 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.   Check out this week’s calendar of activities and actions below! On social media, we will be featuring Pollinator Artwork submitted by the community, as well as the numerous cute (and “not so cute!”) pollinators that live in the world around us!  Also, check out our live Pollinator Poll! Follow us and like our page on Facebook, Twitter, Instagram and LinkedIn!  Monday: Juneteenth and Environmental Justice  As Pollinator Week launches with the celebration of Juneteenth, it is time to renew our commitment to environmental justice while seeking the adoption of transformational policies and practices that recognize the urgency to address disproportionate harm inflicted by toxic pesticide use.   Those fighting for environmental justice understand that the harms inflicted by toxic chemical production and use cause disproportionate adverse effects on people of color—from fenceline communities near chemical production plants to the hazardous and inhumane working conditions in agricultural fields, to […]

(Beyond Pesticides, June 16, 2023) Juneteenth is a celebration of freedom for the last 250,000 enslaved people in Galveston, Texas, but it is also a reminder that justice has not historically been “swift” or complete for Black Americans. The holiday commemorates the abolition of slavery in Texas on June 19, 1865, two and a half years after the Emancipation Proclamation.  According to a 2022 Gallup Poll, 40 percent of Americans know “a little bit” or “nothing at all” about Juneteenth. While this is a significant improvement in comparison to the 60 percent for the aforementioned metric in the previous year (when the holiday was federally recognized), greater public awareness is needed. This holiday is a time for individuals and organizations to acknowledge and reflect on their past and current actions or inactions that perpetuate systemic racism. As known from the history books, the Emancipation Proclamation was signed on January 1, 1863, and the civil war ended on April 9, 1865. Juneteenth is a lesser-known anniversary commemorating the emancipation of enslaved people who received news of their freedom two and a half years after Abraham Lincoln’s freedom proclamation. While the technologies in the 19th century had a much slower travel time, […]

(Beyond Pesticides, June 13, 2023) The specific compounds that comprise one’s scent influence how attractive one is to mosquitoes finds research published in the journal Current Biology by scientists at Johns Hopkins University. Although the findings focus solely on a species of malaria mosquito primarily distributed throughout Sub-Saharan Africa, the results could provide insight into broader concerns over mosquito disease transmission and public health. As it currently stands, personal protective measures and the use of least-toxic repellents are the best methods to address most mosquito problems in the United States. Scientists utilized a mixture and semi-field trials to understand first how mosquitoes became attracted to human hosts. For the field trial, a large facility the size of a college lecture hall was utilized to mimic the sort of open space mosquitoes have available to them in the wild. Eight landing boards were placed in a ring and either heated to human temperature, “baited” with carbon dioxide, or both. Researchers then released 200 mated female mosquitoes that had been starved of food. Scientists tracked the mosquitoes through infrared cameras to determine their trajectory. Only when both heat and carbon dioxide were present did scientists witness high levels of landings on the […]

(Beyond Pesticides, June 12, 2023) In view of the urgent need to enact a transformation to organic agriculture in order to address existential threats to human health, climate, and biodiversity, U.S. Senator Peter Welch (VT) and U.S. Representatives Jimmy Panetta (CA-19) and Alma Adams (NC-12) have introduced Senate and House versions of the Opportunities in Organic Act to reduce cost-barriers, expand access to new markets and resources, and provide support and training. >>Tell your U.S. Representative and U.S. Senators to cosponsor H.R. 3650 and S. 1582, the Opportunities in Organic Act. Thank those who are current cosponsors. Although some existing programs support organic agriculture, transition, and research, they do not level the playing field for organic producers and do not adequately or holistically meet their needs. Organic certification costs and processes remain a barrier for many, and most producers have limited access to organic-specific technical assistance or mentorship – especially in regions with smaller organic sectors. The Opportunities in Organic Act will expand the existing National Organic Certification Cost-Share Program to reduce these barriers and better serve organic producers. The Opportunities in Organic Act has three major components: Organic Certification Cost-Share. The Opportunities in Organic Act will modernize reimbursements for organic certification, […]

(Beyond Pesticides, June 9, 2023) Glyphosate, usually marketed as the herbicide Roundup, has long been the poster child for shoddy regulation by both the U.S. Environmental Protection Agency (EPA) and the European Food Safety Authority (EFSA). In a study published June 1, 2023 in Environmental Health by Axel Mie and Christina Rudén, PhD, of Stockholm University and the Centre for Organic Food and Farming in Uppsala, the authors followed up on earlier work that documented deficiencies in information provided to European Union (EU) regulators by manufacturers. They identified nine studies on developmental neurotoxicity (DNT) that had been submitted to the U.S. Environmental Protection Agency (EPA) but were not disclosed to EU authorities. According to the research, seven of these studies would have “actual or potential regulatory impact.” According to the authors: “Of the nine undisclosed DNT studies, three were sponsored by Bayer and performed in their own laboratory. Three studies were sponsored by Syngenta and performed in their Central Toxicology Laboratory. One study each was sponsored by Nissan Chemicals and Ishihara Sangyo Kaisha (ISK), and these were performed at Huntingdon Life Sciences. For the remaining study, the sponsor and laboratory are unknown to us.” This study is a new example […]

(Beyond Pesticides, June 8, 2023) A study published in Nature Communications finds that climate-induced thawing of permafrost (a ground that remains completely frozen for two or more years) threatens approximately 4,500 industrial sites in regions of the Arctic. These thousands of industrial sites used to store hazardous substances have an estimated 13,000 to 20,000 contaminated locations. Not only do these regions pose a grave ecological risk to the Arctic, but they threaten the entire globe. Many studies warn that thawing permafrost in the Arctic region can prompt the reemergence of greenhouse gases (e.g., methane and carbon dioxide), microbes, and hazardous chemicals (e.g., banned pesticides like DDT, heavy metals, etc.). Gases, microbes, and chemicals can drift near the poles, becoming entrapped in ice under the accumulating snowfall. As the global climate continues to rise and the climate crisis worsens, studies like this heed warning of potential adverse effects as ice encapsulating these toxic chemicals melt. Upon melting, some chemicals can volatilize back into the atmosphere, releasing toxicants into the air and aquatic systems, with the ensuing consequences. Microbes frozen for thousands to millions of years can also emerge from thawing permafrost, with unknown implications on human, animal, and ecosystem health. The melting permafrost is already […]

(Beyond Pesticides, June 6, 2023) Government agencies in Hawaii are making preparations to release a small parasitoid in an attempt to control infestations of coffee berry borer (CBB) in the state, according to a release published by the University of Hawaii.  “This biological control agent has the potential to make significant positive economic impacts in the Hawaiʻi coffee industry, and offers an environmentally safe way to manage CBB,” says Mark Wright, PhD, professor at UH. “The Hawaiʻi coffee industry is economically and culturally significant, and we hope that this work will improve the lives of many people associated with the industry.” The planned release comes at a time of increasing interest in nontoxic biological pest management as a means of reducing the harmful effects of industrially produced pesticides. As early as fall 2023, the U.S. Department of Agriculture’s Agriculture Research Service (USDA ARS) and UH’s Department of Plant and Environmental Protection Services plan to release thousands of parasitic wasps throughout coffee growing areas in Maui, O’ahu and the Big Island. The parasitoid in question is Phymastichus coffea, a wasp that lays its eggs in the abdomen of coffee berry borers. According to researchers, the wasp becomes attracted to the coffee […]

(Beyond Pesticides, June 5, 2023) Butterflies—the most attractive of our insect fauna—are disappearing at an appalling rate, largely due to pesticide use. Recent studies have documented declines of almost 50% from 1990 to 2011 in Europe (with trends continuing), of 58 percent between 2000 and 2009 in the U.K., and of 33% from 1996–2016 in the state of Ohio in the U.S. Even steeper declines have been documented for Monarch butterflies, with an 80 percent decline of Eastern monarchs and 99 percent decline of Western monarchs. Tell EPA to eliminate pesticides that threaten butterflies. Tell the U.S. Fish and Wildlife Service and Department of Interior to help bring back butterflies by eliminating the use of pesticides that threaten them. Tell Congress that EPA and other agencies need to do their job and protect our most charismatic insects. Last year, EPA admitted that three neonicotinoid pesticides are “likely to adversely affect from two-thirds to over three-fourths of America’s endangered species—1,225 to 1,445 species in all,” including many butterfly species. On May 5 of this year, EPA released new analyses of these neonics’ effects on endangered species. EPA’s analyses focus on the species most at risk of extinction, and the results represent […]

(Beyond Pesticides, May 31, 2023) A study published in Chemosphere supports accumulating scientific research confirming that prohibited and current use pesticides are readily detectable in the human placenta. All pregnant women experience exposure to a mixture of complex pesticides like DDT (prohibited organochlorine pesticide [OCP]) and chlorpyrifos (current use organophosphate [OP]), with concentrations high enough to increase possible adverse health risks to the fetus through a placental transfer of chemicals. Prenatal development in the intrauterine environment is one of the most vulnerable periods of exposure, as the fetus is most susceptible to the harmful effects of chemical contaminants. Many studies indicate that prenatal and early-life exposure to environmental toxicants increases susceptibility to diseases, from learning and developmental disabilities to cancer. Given the over 1,300 research studies that demonstrate the link between pesticide exposure and general health effects, studies like this can help government and health officials identify how pesticides’ impact on the body elevates health concerns, especially for future and developing generations. The authors note, “This study highlights the urgent requirement for implementing alternative pest-control methods in agriculture, involving a reduction of chemical pesticides application. Due to the vital role of the placenta in fetal development and its non-invasive sampling, this kind of […]

(Beyond Pesticides, May 30, 2023) On Endangered Species Day, May 19, the U.S. Environmental Protection Agency (EPA) revealed an unfortunate degree of hypocrisy in its claims to protect endangered species from pesticides. Tell EPA and Congress that dwindling biodiversity is an existential crisis that requires removing serious threats posed by pesticides. EPA announced that it “is publishing a group of StoryMaps to raise public awareness about protecting endangered species from pesticides.” It continues, “Through its Vulnerable Species Pilot, EPA has been identifying endangered species that are vulnerable to pesticides, developing mitigations to protect them from pesticide exposure, and will apply the mitigations to many types of pesticides.” However, pesticide use is a major cause of declining biodiversity, which is manifested in extinctions, endangered species, and species vulnerable to environmental disturbances—including climate change, habitat fragmentation, and toxic chemicals. If EPA is serious about protecting biodiversity, it must look first at the ways it has created the crisis in the first place. Studies upon studies upon studies show that pesticides are a major contributor to the loss of insect biomass and diversity known as the “insect apocalypse,” particularly in combination with climate change. Insects are important as pollinators and as part of […]

(Beyond Pesticides, May 26, 2023)The use of pesticides in agriculture, transportation, and domestic settings has created a disastrous conflict for the human species. Two irreconcilable facts confront humans as they try to adapt to the consequences of earlier choices: One, industrial civilization came to believe that because some insects, fungi, and other organisms like to eat the same plants humans eat, humans can kill them with impunity; two, because some insects and other organisms are necessary to the health and reproduction of plants, humans need to protect them. At no point in history have people acknowledged that it is very difficult to kill the “bad” actors while protecting the “good” ones. There are not really two sides to the biological fact; rather, pesticides and biodiversity meet each other on a single plane, like a Möbius strip. Among the most dire effects of pesticides are their ruination of pollinators. Bees spring to mind as our primary pollinators, but they are by no means the only ones. Butterflies, often regarded as mere ornamental additions to a landscape, are actually significant pollinators themselves. Monarchs pollinate many flowers, including calendula and yarrow. Other butterflies pollinate dill, celery, fennel, cilantro, lettuce, peas, and basil, among […]

(Beyond Pesticides, May 23, 2023) Scientists have developed a nontoxic method to deter rodents from feeding on freshly planted seeds, publishing the approach in the journal Nature Sustainability this month. The new tactic, which confuses mice through olfactory misinformation, has the potential to significantly reduce the use of hazardous rodenticides in farming operations. The approach comes at a time of increased scrutiny around rat poisons, specifically second-generation anticoagulant rodenticides (SGARs), which can result in the secondary poisoning of predators that eat poisoned rodents. Researchers set out with the intent of finding a safe alternative to rodenticides that can effectively reduce pest damage without the need for hazardous interventions. “A simpler approach to pest damage is to manipulate decisions making by problem animals and disrupt their ability to find at-risk foods,” the study indicates. Contrary to the promises of the pesticide industry that its products are ‘silver bullets’ for pest management, the authors propose weaponizing misinformation over brute force by fooling mice into thinking their sought-out food source is not there. Mice and other rodent foragers most often rely on scent and odor to determine where food is located. In the context of this study, farmers plant wheat seeds along rows, […]

(Beyond Pesticides, May 23 2023) New research is zeroing in on the role of 10 commonly used pesticides in the development of Parkinson’s. Published in the journal Nature Communications by a team of scientists lead by researchers at the University of California, Los Angeles, the study focused on the toxicity of these pesticides to neurons that have been found to lead to the presentation of the disease. Research is increasingly focusing on environmental exposures, and pesticides in particular, as a major factor in the development of Parkinson’s. This study adds further evidence that this line of research is a valid and worthwhile undertaking for the nearly one million people in the United States struggling with this incurable disease. [The authors note that the herbicide paraquat’s strong connection to Parkinson’s is not addressed in this study, but is the focus of a separate manuscript.] Scientists sought to further focus on which pesticides were most likely to be playing a role in Parkinson’s development. Records from California’s vast pesticide use database aided the search. From a comprehensive pesticide-wide association study, 53 of 288 pesticides screened were found to be linked to Parkinson’s. Scientists then took these 53 pesticides and conducted live-cell imaging […]

(Beyond Pesticides, May 22, 2023) Since most of the domestically produced fresh produce we eat comes from California, what happens in the state is of concern to most consumers. The California Department of Pesticide Regulation (DPR) has made minor adjustments to its proposal to remove existing limits on the use of 1,3-dichloropropene (1,3-D or Telone), allowing Californians to breathe much more 1,3-D than state toxicologists at the California Office of Environmental Health Hazard Assessment—charged with establishing safe limits of exposure and enforcing Prop 65—say is safe, highlights the dangers to which farmworkers are routinely exposed. It is outrageous that the U.S. Environmental Protection Agency (EPA) would allow farmworkers—whose labor was judged “essential” during the pandemic—to be routinely exposed to highly toxic pesticides, which could be replaced by organic practices. You may have commented on this early in the year, and now we need to follow up with a strong message to protect those who harvest the nation’s food.  Tell EPA, Congress, and CDPR to cancel the registration of all toxic soil fumigants and encourage organic alternatives. 1,3-D is a pre-plant soil fumigant registered for use on soils to control nematodes. It is allowed on all crops and is often used with chloropicrin, another highly toxic […]

(Beyond Pesticides, May 19, 2023) Agricultural intensification is the leading factor driving declines in bird populations across Europe, according to research published in the Proceedings of the National Academy of Sciences (PNAS) this week. Among all potential anthropogenic impacts, agricultural intensification, in particular pesticide and fertilizer use, was found to be more dramatic than forest alterations, urbanization, and climate change. “I don’t think a study has looked at all these factors in one go, in such a sophisticated fashion, correcting for one variable alongside another; and it comes out with a very clear message,” lead author Richard Gregory, PhD, of UK nonprofit The Royal Society for the Protection of Birds, told The Guardian. Researchers utilized data dating back to the early-1980s, including annual bird surveys and national and supranational analyses, as well as information on land use cover, farm inputs, and temperature changes within the time frame. Bird habitat and ecological traits were also considered in the context of declines, and a statistical analysis aided researchers in capturing trends over time. Results confirmed that birds are overall experiencing significant declines in Europe, with data recording 25% losses in bird abundance since 1980. However, certain groups of birds are faring worse […]

(Beyond Pesticides, May 17, 2023) British biotechnology company Oxitec is withdrawing its application to release billions of genetically engineered mosquitoes in California, according to a recent update from the California Department of Pesticide Regulation. The withdrawal is a victory for environmental and health campaigners concerned about the release of a novel mosquito that the U.S. Environmental Protection Agency (EPA) had previously authorized under an “experimental use” permit. “Genetically engineered mosquitoes are an environmental justice issue for Tulare County residents who should not be human experiments,” said Angel Garcia, codirector of the statewide coalition Californians for Pesticide Reform and Tulare County resident in a press release. “We are already impacted by some of the worst pollution problems in the state and deserve prior informed consent to being part of an open-air biopesticide experiment. Ahead of any future proposal for genetically engineered insects, DPR needs to have robust regulations in place that protect community members, and meaningful, inclusive public participation in any decision making.”     Oxitec began releasing its GE mosquitoes over a decade ago, first introducing the insects in the Brazilian town of Itaberaba. The company has made efforts to launch its mosquitoes in the United States, likely as a way […]
