(Beyond Pesticides, April 26, 2023) Organic methods of honey bee management are just as or more effective than conventional, chemical-intensive management systems, according to research published this month in the journal Scientific Reports by a team of Penn State scientists. This finding is important as managed pollinators continue to be under stress primarily from pesticide exposure, but also other factors, such as disease, pests, climate change, and habitat loss. In this context, beekeeping management practices can mean the difference between a colony thriving, surviving, or declining. “Beekeeping management is a key aspect of honey bee health because it can help mitigate some of the negative effects caused by these stressors,” said study co-author Robyn Underwood, PhD, of Penn State Extension. “For example, supplemental feeding can mitigate a lack of flowering plants nearby for foraging, and beekeepers can manage pests such as Varroa mites with cultural, mechanical and chemical control practices.” Scientists developed protocols to test different beekeeping management systems through participatory science. Thirty beekeepers were invited to work with scientists using protocols on experimental design, applying three different management approaches: i) conventional chemical; ii) organic; and iii) management without inputs. “We wanted to replicate what beekeepers were doing in their […]

Today, Beyond Pesticides released a special issue, Transformative Change: Informed by Science, Policy, and Action of its journal, Pesticides and You, with a compendium of “shocking scientific findings that compel us to act in our communities, states, and as a nation and world community.” The 168-page issue documents the last year of scientific, peer-reviewed articles, policy deficiencies, and action for change that intersect not only with petrochemical pesticides and fertilizers, but with existential health crises, biodiversity collapse, and the climate emergency.

(Beyond Pesticides, April 21, 2023) Into the annals of “entropic methods of agricultural pest control” arrives recent research showing that pests are, unsurprisingly, developing resistance to a genetically engineered (GE) biopesticide used for more than 90% of U.S. corn, cotton, and soybeans. Bt (Bacillus thuringiensis) is a naturally occurring bacterium; the versions deployed in conventional agriculture are engineered into Plant Incorporated Protectants (PIPs) — GE ingredients “inserted” into seeds for multiple kinds of crop plants. These PIPs target multiple crop-destructive insect species, including (in larval form) the corn rootworm and cotton bollworm, in particular. Beyond Pesticides continues to warn that “controls,” whether synthetic chemical pesticides or GE “biological” agents (such as GE Bt) that target living things (e.g., pests and weeds) are not sustainable over time because — in addition to the harms they cause — the issue of resistance will ultimately thwart their efficacy. There are two basic categories of genetic engineering employed in conventional agriculture. One technology transfers genetic material into seed to make plants tolerant of specific herbicide compounds that will be applied after planting (for example, the infamous “Roundup Ready,” glyphosate-tolerant seeds and plants). The other comprises plant-incorporated protectants (PIPs), in which the genetic material introduced […]

(Beyond Pesticides, April 18, 2023) Health officials in France are alerting the public that a majority of drinking water samples tested by the government contain the presence of the highly toxic fungicide chlorothalonil. The findings highlight a stark divide between regulations and public health management in the European Union and United States. While EU member states have banned this chemical and are working to understand and address lingering effects, tens of millions of pounds of chlorothalonil continue to be sprayed throughout the U.S. annually. French officials say they conducted this research after researchers in Switzerland found evidence of the fungicide in drinking water. A few years ago, Swiss scientists released a report showing Evian bottled water, touted for its claims of purity, was found to contain measurable levels of chlorthalonil.  “The fact that even the Evian springs in the French Alps, which are hardly affected by humans, contain pesticide residues is alarming and shows the far too careless handling of these substances,” Roman Wiget, president of the international drinking water association AWBR told the German-language Swiss weekly at the time. The EU banned uses of chlorothalonil in 2019, due to concerns over water contamination, the effects of such contamination on fish […]

(Beyond Pesticides, April 14, 2023) In March, scientists at the National Marine Fisheries Service (NMFS) issued a draft Biological Opinion (BiOp) stating that carbaryl and methomyl — two commonly used carbamate insecticides — cause significant harm to dozens of already-endangered fish species in the Pacific Northwest’s Columbia, Willamette, and Snake rivers. The BiOp indicates that these toxic compounds, in wide use on orchards and field vegetables throughout the Willamette Valley, the Columbia River Gorge, and southeastern Washington, will likely threaten scores of species on the Endangered Species list: 37 species at risk from carbaryl and 30 from methomyl. In addition, the BiOp says, “both are likely to harm or destroy many areas designated as critical habitat for endangered species.” The mitigation measures proposed by NMFS and the U.S. Environmental Protection Agency (EPA), in light of this BiOp, are likely to be inadequate to the problem, given that both compounds can drift through air and/or migrate into groundwater and generate toxic runoff. These two neurotoxic insecticides, carbaryl and methomyl, are very toxic to bees, birds, fish, and other aquatic organisms. In addition, carbaryl is a likely human carcinogen and an endocrine disruptor, and has harmful impacts on multiple bodily systems. Methomyl is […]

(Beyond Pesticides, April 5, 2023) A collective of Mayan beekeepers (Colectivo de Comunidades Mayas) in Mexico are implicating chemical industry giant Bayer/Monsanto in a massive die-off of more than 300,000 bees among their combined apiaries. According to Mexico News Daily, the total value of losses represent a staggering $663,000 U.S. dollars (12 million pesos). The incident is the latest instance of the pesticide  and agrichemical industry setting up shop in a local community and wrecking the health of the local ecology. Mayan beekeepers explain that Bayer/Monsanto recently started operations on a ranch near Crucero Oxá in the southern Mexican state of Campeche. A local businessman placed the 50 hectare ranch on loan to the company. Since that arrangement, the company has aerially sprayed row crops like corn and soy with undisclosed chemicals. “One of Bayer’s engineers or technicians allowed us to take samples from one of their crops after the bees started to die,” said beekeeper José Manuel Poot Chan, to the newspaper La Jornada Maya. “We are exhausting all possible legal instances, while members of the Welfare Ministry already came to offer humanitarian social aid to cover part of the damages.” Beekeepers suspect that the company is using the […]

(Beyond Pesticides, March 30, 2023) A study published in Ecotoxicology and Environmental Safety finds that the commonly used herbicide, atrazine, promotes breast cancer development through suppression of immune cell stimulation, and thus function, and upregulation of enzymes mediating tumor development. According to the Centers for Disease Control and Prevention (CDC), breast cancer is a disease that causes breast cells to grow out of control, with the type of breast cancer depending on the cells themselves. Several studies and reports, including U.S. Environmental Protection Agency (EPA) data, identify hundreds of chemicals as influential factors associated with breast cancer risk. Breast cancer is the most common cancer among women, causing the second most cancer-related deaths in the United States. Past studies suggest genetic inheritance factors influence breast cancer occurrence. However, genetic factors only play a minor role in the incidence of breast cancer, while exposure to external environmental factors (i.e., chemical exposure) appears to play a more notable role. One in ten women will receive a breast cancer diagnosis, and genetics can only account for five to ten percent of cases. There are grave concerns over exposure to endocrine (hormone) disrupting chemicals and pollutants that cause adverse health effects. Therefore, advocates point to the need for national […]

(Beyond Pesticides, March 29, 2023) A commonly used slug killer known as metaldehyde can hamper the growth of garden vegetables. This finding, published in the journal Scientific Reports, provides a helpful reminder for gardeners to seek out non and less toxic management approaches as spring comes into full swing and pests arrive. While slugs can be devastating to seedlings this time of the year, some simple approaches can help reduce pest pressure while maintaining the quality and integrity of one’s garden plot. Metaldehyde is a molluscicide that is applied through a bait, causing slugs to expel mucus and completely dry out. It has been in use since the 1940s, but like many pesticides from that era, there are a range of hazardous impacts that were not adequately studied at the time and are only beginning to be understood today. In mammals, ingestion of the chemical has been linked to neurotoxicity, including tremors, loss of coordination, rapid breathing and heart rate, vomiting, seizures and even death. Although humans are less likely to eat the baits, these risks are particularly pronounced for children and pets. Data on the impacts this material poses to plant growth is few and far between. To remedy […]

(Beyond Pesticides, March 28, 2023) High concentrations of fully intact, never broken down DDT remain on the California seafloor decades after it was dumped off its southern coast in the middle of the 20th century. “We still see original DDT on the seafloor from 50, 60, 70 years ago, which tells us that it’s not breaking down the way that [we] once thought it should,” University of California Santa Barbara scientist David Valentine, PhD, told the Los Angeles Times. “And what we’re seeing now is that there is DDT that has ended up all over the place, not just within this tight little circle on a map that we referred to as Dumpsite Two.” These findings underscore the enormity of legal and regulatory decisions to approve production of hazardous chemicals. While many may believe the legacy of DDT ended with its ban in the early 1970s, the California findings raise a deeper problem not only with U.S. chemical policy, but also the response from well-meaning environmental nonprofits that continues to play out to this day. As many in the environmental community invest tremendous resources in seeking to ban problematic pesticides or chemicals of the day after the contamination has occurred […]

(Beyond Pesticides, March 27, 2023) In a move labeled “risk mitigation”—that is, mitigation of the risk to its shareholders—Bayer-Monsanto announced in 2021 that it would phase out Roundup™ products containing glyphosate for the residential lawn and garden market as of January 2023. In taking this action, Bayer-Monsanto is making no admissions, and glyphosate products will still be available to farmers. However, Lowe’s and Home Depot are still selling the glyphosate-based lawn and garden products. Tell Lowe’s and Home Depot to eliminate Roundup™ and other toxic pesticides, promote organic practices, and sell organic compatible products.  In fact, since this is a voluntary reformulation, and Bayer-Monsanto has decided its own timing, the company cannot be held accountable to anything. The company could change its mind, and stores can continue to sell the glyphosate-based products as long as they want. And keep in mind that replacement versions of Roundup™ products are also toxic. Roundup® Dual Action, for example, contains the following active ingredients: triethylamine salt of triclopyr, fluazipop-P-butyl, diquat dibromide, and ammonium salt of imazapic. Thus, Bayer/Monsanto announces that it is changing the formulation of Roundup and moving away from glyphosate, while continuing to sell Roundup™ products formulated both with and without glyphosate—leaving consumers unaware of their risks. The U.S. Environmental Protection Agency (EPA) has […]

(Beyond Pesticides, March 23, 2023) A case report article published in Frontier in Public Health confirms one of the first reported deaths from inhalation of the fumigant 1,3-dichloropropene (1,3-D or Telone) during work, resulting in acute renal (kidney) failure, hyperkalemia (high potassium levels in the blood), and brain edema (swelling). 1,3-D is a highly toxic fumigant used on a variety of crops, but primarily on potatoes, tobacco, strawberries, peanuts, and tomatoes to manage unwanted nematodes in soils. The chlorine-containing compound used in a greenhouse space entered the body of a 50-year-old man in China, being absorbed through the respiratory tract. Despite dilution from his wife, the compound was still strong enough to cause harm to human health. Without proper ventilation and personal protective equipment, wearing merely a surgical mask did not adequately defend against exposure to 1,3-D. This case represents the broader issue of how toxic chemical compounds can enter the body, causing physiological damage. Specifically, pesticides can increase the permeability (absorptiveness) of the blood-brain barrier that filters various molecules entering the brain from the circulatory system. However, the permeation of pesticide molecules elevates the expression and accumulation of soluble proteins in the brain involved in neuroinflammation, which plays a critical role in […]

(Beyond Pesticides, March 21, 2023) Placing honey bee hives in agricultural areas creates stress that leads to microbial imbalances, according to research published in Scientific Reports by Croatian scientists this month. The research highlights the fragility and absurdity of chemical-driven agricultural systems dependent upon both pollinators and products that harm or kill off these sensitive species. While regulators in the United States continue to prop up unsustainable practices, more and more consumers are seeking out and engaging with the key alternative to this system by supporting organic farms and foodstuffs at their farmers market and grocery store. Scientists began by creating 33 colonies from three apiaries within an agricultural region in Croatia, utilizing four brood frames, two honey frames, and mated queens. Of these 33 newly created hives, 22 were relocated to a separate agricultural region, and 11 were placed roughly six miles away from a nature preserve and considered a semi-natural area. A separate group of 10 hives that had been established on a small island (Unije, Croatia) in the Adriatic Sea were included in the study in order to represent a completely natural location. After roughly two weeks of colony formation, scientists collected samples to represent the multiple […]

(Beyond Pesticides, March 14, 2023) A study published in Environmental Research and Public Health finds occupational pesticide exposure increases the risk of sleep disorders among farmworkers and pesticide applicators. Specifically, many pesticides, like organophosphates (OPs), are detrimental to neurological function through inhibition of the enzyme acetylcholinesterase (AChE) responsible for ending a neurotransmission event after relaying the necessary information. Without an end to neurotransmission events, individuals experience a buildup of acetylcholine, resulting in convulsions, headaches, weakness, impacts on bodily senses, and other cognitive/mental changes. In addition to illnesses from chemical exposure, inadequate sleep has links to several chronic diseases like type 2 diabetes, cardiovascular disease, obesity, and depression. Therefore, given research links to sleep-related disorders and bodily functions, including endocrine, metabolic, neurological, and cognitive disorders, studies like this can help government and health officials identify how pesticides’ impact on the brain elevates health concerns. The study notes, “The study’s findings can be used to create strategies for addressing mental health issues and promoting mental health and quality of life.” Researchers assess the sleep patterns among individuals living in southeast Spain, near the coast of Almeria, where chemical-intensive agriculture from greenhouses is prevalent. Of the 380 participants in the study, 189 were […]

(Beyond Pesticides, March 9, 2023) A study published in Environmental Research finds exposure to organophosphate (OP) compounds during pregnancy, or prenatal OP exposure can cause shortfalls in language development abilities at 18 months, stifling preschool-age language expression. Additionally, a timely and co-occurring study published in Environmental International confirms similar results, highlighting that chlorpyrifos (an organophosphate) impedes neurological and psychological development, including language communication and all motor skills of offspring at 12 and 18 months old. Prenatal development 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 research links to pesticide exposure and neurological and cognitive development, studies like this can help government and health officials identify how pesticides’ impact on the brain elevates health concerns. The Environmental Research authors note, “The etiology [cause] of language development is complex, and this work further highlights the importance of the prenatal environment as a mechanism of influence that are associated with deficits in early language acquisition and ability, which could signal increased behavioral problems and academic difficulties in later childhood that extend […]

(Beyond Pesticides, March 7, 2023) An old Kerr-McGee Wood Treatment Facility is still causing health issues among residents in Springfield, Missouri. The former site of pressure-treated railroad tie production remains contaminated with creosote, a concoction of dangerous chemicals including polycyclic aromatic hydrocarbons, phenols, and creosols. While residents are still dealing with lingering effects of a now shuttered production site, the U.S. Environmental Protection Agency (EPA) is set to reregister creosote (wood preservatives are regulated as pesticides in the U.S.), perpetuating the harm caused by this material despite the wide availability of alternatives. The wood treatment facility in question operated for nearly 100 years, releasing significant levels of creosote-related chemicals throughout the immediate region. The Kerr-McGee Corporation spun off its liability for a range of hazardous sites previously under its control to a separate company called Tronox, which subsequently declared bankruptcy in 2009. Andarko Petroleum then purchased Kerr-McGee, but, during bankruptcy proceedings, Tronox filed a complaint against both Andarko and Ker-McGee, alleging fraudulent conveyance of the liabilities. As EPA explains, “At the core of the plaintiffs’ complaints is the allegation that the Defendants fraudulently transferred valuable assets out of Tronox and left Tronox with insufficient funds to pay the billions of […]

(Beyond Pesticides, March 7, 2023) Exposure to glyphosate (Roundup) and its breakdown products is associated with an increased risk of liver and metabolic disorders in children and young adults, according to research published in Environmental Health Perspectives earlier this month. While glyphosate has developed a well-deserved reputation as a carcinogen, research is finding that cancer is one of a myriad of chronic diseases associated with the notorious chemical. As this body of literature grows, growing awareness by the public is increasing pressure on the U.S. Environmental Protection Agency to cancel its allowed uses. Researchers began their investigation concerned about the rise of liver disorders and metabolic syndrome among young people. This trend has been pronounced among populations of color. The worrying increase has led many to consider synthetic chemical exposure as a contributing factor, as lack of diet and exercise is unlikely to account for the entirety of the increase. To better understand these impacts, researchers enrolled existing participants in the CHAMACOS (Center for the Health Assessment of Mothers and Children of Salinas) study, a long running cohort of mothers and their children born between the years 2000 and 2002 in the Salinas Valley of California. Enrolled participants consistent mostly […]

(Beyond Pesticides, March 6, 2023) After the Trump EPA was blocked from weakening the application exclusion zone (AEZ) provisions for protecting farmworkers, the rules reverted to the Obama era rules. Now, EPA proposes to reaffirm part of that rule, while accepting some of the weakening amendments from the Trump administration. Tell EPA to strengthen pesticide rules to protect farmworkers. Tell President Biden to sign the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families.    EPA’s Worker Protection Standards (WPS) are rules that govern labor safety standards within federal pesticide law (the Federal Insecticide Fungicide and Rodenticide Act, or FIFRA). Farmworkers are not covered for toxic chemical exposure by the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA), and WPS have long been criticized by farmworker, labor, and health advocates for providing insufficient protections for farmworkers, their children and communities. Under the WPS, AEZs are buffer zones where people are not allowed to enter during the course of a pesticide application. Like all buffer zones, they are designed to allow application of toxic pesticides while providing a nominal degree of protection. Pesticides drift long distances when being applied and they […]

(Beyond Pesticides, March 2, 2023) On February 22, a group of 65 nonprofit organizations (including Beyond Pesticides) filed a citizen petition with the U.S. Environmental Protection Agency (EPA) that asks the agency to close a gaping — and well exploited — regulatory loophole by revoking a 1984 regulation that waived efficacy data requirements in pesticide evaluations. This means that EPA has, for 39 years, registered pesticides without demonstrated proof of efficacy and benefits. The petition is aimed primarily at the widespread use of neonicotinoid insecticides (neonics), which are so harmful to hundreds of species — and to bees, other pollinators, and birds, in particular — that many advocates have insisted they should be banned altogether. Beyond Pesticides has advocated for a neonics ban because of their extensive harms to pollinators, multiple other organisms (including humans), ecosystems, and natural resources. The Center for Food Safety, Pesticide Action Network North America, Center for Biological Diversity, Beyond Pesticides, and other advocates have filed lawsuits in recent years to get EPA to act protectively on neonics and other pesticides. The coalition of groups in the subject case seeks to rein in a plethora of harmful impacts of neonics, given EPA’s overall lack of protective action. (For […]

(Beyond Pesticides, March 2, 2023) Populations experiencing higher levels of environmental pollutant exposure, specifically pesticides, also experience a higher rate of irritable bowel syndrome (IBS), according to a study published in Environmental Toxicology and Pharmacology. IBS is a gastrointestinal disorder that causes abdominal pain or discomfort and changes in bowel behaviors. IBS affects 25 to 45 million individuals in the U.S., mostly female (two-thirds). Additionally, a quarter to half of all gastrointestinal-related visits are for IBS symptoms. Despite the unknown etiology of IBS, ample evidence demonstrates environmental contaminants, like pesticides, negatively affect the gut microbiota, causing a microorganism imbalance and resulting in inflammation associated with IBS. The gut, also known as the “second brain,” shares similar structural and chemical parallels to the brain. The microbiota in the gut plays a crucial role in lifelong digestion, immune and central nervous system regulation, as well as other bodily functions. Although studies show how chemical exposures affect overall human health, a growing body of peer-reviewed scientific literature is now questioning how these toxic chemicals influence gut health and the subsequent occurrence of diseases. The study notes, “These findings may help to understand the relationship between pesticide exposure and IBS; however, more epidemiological and experimental research is needed to understand […]

(Beyond Pesticides, March 1, 2023) Fungicides sprayed on chemically farmed strawberries reduce their flavor quality, according to research published in the Journal of Agricultural and Food Chemistry this week. This explanation is a major insight for frustrated consumers who may remember when the strawberries sold at retail contained deeper, more complex flavors. As the agrichemical industry claims that dangerous pesticides are needed to grow food to feed the world, it is evident these practices health and environmental hazards, but also affect the quality of the food grown. As savvy shoppers and gardeners already know, buying and growing organic addresses this range of issues, improving flavor while protecting wildlife and public health. Scientists developed their study to better understand the mechanisms leading to flavor deterioration by growing strawberry plants in a greenhouse with chemical-intensive practices, including the use of synthetic fertilizers. One group was treated with the fungicide boscalid, another with the fungicide difenconazole, and a control group received no spray. Fruits were sprayed beginning at the green, small fruit stage, a total of two times, and collections from each group were taken at the white, turning, and red fruit stage (zero, three, and seven days after the second pesticide application). […]

(Beyond Pesticides, February 27, 2023) California’s Department of Pesticide Regulation (DPR) is asking for comments on its “Sustainable Pest Management (SPM) Roadmap” by 5 pm (PST) March 13, 2023. While recognizing problems inherent in traditional integrated pest management (IPM), DPR’s roadmap is directing us to a destination that includes another generation of exposure to the worst of the worst pesticides—while failing to embrace the elimination of farm inputs harmful to ecosystems and the capacity of soil biology to cycle nutrients and draw down the maximum amount of atmospheric carbon. The Roadmap’s off-handed rejection of organic practices, rather than building on organic systems, creates a lost opportunity for adopting a holistic and serious solution to the current crises of health threats from pesticides, biodiversity collapse, and the climate emergency. Tell DPR to revise its destination to immediately eliminate the worst pesticides and implement wide scale transition to organic practices. DPR’s Roadmap states these goals: By 2050, eliminate the use of Priority Pesticides by transitioning to SPM. By 2050, SPM will be adopted as the de facto pest management system in California. DPR says “The criteria for classifying pesticides as “Priority Pesticides” include, but are not limited to, hazard and risk classifications, […]

(Beyond Pesticides, February 23, 2023) A father’s exposure to occupational (work-related) chemicals, including pesticides, around the time of his partner’s pregnancy, has an association with a higher risk of infant congenital heart defects (CHDs), according to a Japanese study published in Environmental Health and Preventive Medicine. The prevalence of infant CHDs is one of the most common genetic (congenital) diseases worldwide. However, the etiology of CHD includes both genetic and environmental factors. Heart diseases are among the leading causes of death worldwide, and heart conditions are one leading cause of disability in the U.S. Research, including this study, demonstrates environmental pollutant exposure can increase the risk of developing cardiovascular disease, including stroke, heart attack, heart failure, atrial fibrillation, and cardiac arrest. Considering chemical exposure exacerbates adverse disease effects, reviews like these highlight the significance of evaluating synergism between diseases and toxic chemicals to safeguard human health. Therefore, researchers are “suggesting the importance of the management of paternal occupational exposures for the prevention of infant CHDs. Further studies using biomarkers of occupational exposure are warranted.” To investigate the risk of CHDs in infants, researchers in this study examine fathers’ work-related exposure to toxic chemical compounds, frequency of pesticide use, and synergetic mixtures of chemical compounds. […]

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