(Beyond Pesticides, May 3, 2022) Exposure to a commonly used fungicide considered to be â€slightly toxic or nontoxic’ to pollinators makes male mason bees less likely to find a mate, jeopardizing future generations of critically important pollinators. This determination comes from research recently published in the Journal of Applied Ecology by scientists at Germany’s University of WĂĽrzburg. The timing of these findings comes after the U.S. Environmental Protection Agency (EPA) reapproved uses of fenbuconazole, the fungicide in question, late last year without completing all required studies on pollinator health effects. Horned mason bees (Osmia cornuta), a solitary bee species, have a complex mating process that includes a range of “pre-copulatory behaviors” used by male bees attract females. Males create thoracic vibrations with their flight muscles, rub the eyes of female bees with their antennae, and emit a distinct odor from their body. If the female likes the presentation, she will mate with the male. Otherwise, she will move him to the side and wait for another male to try to win her affection. To see how this process was influenced by pesticide exposure, researchers conducted a range of different experiments. For the first, newly emerged male and female bees were […]

(Beyond Pesticides, May 2, 2022) Lawns occupy 40 million acres, or 2% of the land in the U.S. Their maintenance typically involves pesticides and fertilizers that kill pollinators and soil life and wash into streams, where they do more damage. Lawn maintenance also involves a lot of mowing. While mowing is an effective way to encourage grasses over most broadleaved plants, it also has broader ecological impacts. The 3,600 species of bees in the U.S. and Canada range from large bumblebees to tiny sweat bees. There are many things you can do in your yard and community to protect these bees—starting with managing lawns and landscapes organically and planting flowers favored by bees and other pollinators. This one—No Mow May—requires less work. Participate in No Mow May. Manage your landscape organically. Plant flowers for pollinators. Send a message to your mayor. No Mow May began with research by Plantlife in the UK and was taken up by property owners in Appleton, WI, who demonstrated that “homes that participated in No Mow May had more diverse and abundant flora than regularly mowed green spaces throughout the city.” May is the month when many bees emerge from hibernation throughout the U.S. and […]

(Beyond Pesticides, April 26, 2022) Using pesticides to reduce the number of ticks in residential areas does not translate to lower rates of tick-borne disease in humans. This finding is the culmination of research overseen by scientists at the U.S. Centers for Disease Control and Prevention (CDC), which have been studying the effectiveness of pesticides to manage tick bites and tick borne-diseases for over a decade. While earlier research focused on direct pesticide applications to individual household lawns, the most recent publication, under early release in the Journal of Emerging Infectious Diseases, represented a broader, neighborhood-wide implementation of control measures. Yet in both instances, pesticide use did not play a role in reducing tick-borne disease. The studies are a stark warning for states and communities considering vector disease spray campaign for ticks in a similar manner to mosquito spraying. “The bottom line is that toxic pesticide use is not the answer to tick bites or tick-borne disease,” said Beyond Pesticides executive director Jay Feldman. “To manage ticks, we must embrace ecological solutions that work with natural processes and education campaigns emphasizing personal protection.” Researchers set out to test two methods of broad area tick control in 24 residential neighborhoods in […]

(Beyond Pesticides, April 21, 2022) A literature review published in Royal Society finds that â€inert’ ingredients’ in pesticide formulations adversely affect the health of bees and other wild pollinators. Inert ingredients, also known as “other” ingredients, and not disclosed by name on pesticide product labels, facilitate the action of active ingredients targeting a specific pest. Although both ingredients have chemical and biological activity, most studies on agricultural chemical toxicity focus on the active ingredient, assuming that inert ingredients are “nontoxic.” The U.S. Environmental Protection Agency (EPA), in regulating pesticides, assesses the toxicity of individual active ingredients on bees through various testing methods. However, there are no requirements for EPA to test inert ingredients to the same degree, despite evidence demonstrating these chemicals harm pollinators. Moreover, EPA does not require pesticide manufacturers to disclose the inert ingredients used in any product as the information is confidential. Both wild and commercial bees and other pollinators encounter multiple stressors, including pesticides, parasites, and poor nutrition, that act together to increase the risk of bee mortality. Therefore, reviews like these highlight the need for pesticide testing to consider the effects of all product ingredients, regardless of perceived toxicity. The researchers caution, “We argue that â€inert’ ingredients […]

The organic solutions to problems highlighted in the latest issue of Pesticides and You—based on the importance of healthy ecosystems and public health protection—are within reach, and the data creates an imperative for action now that phases out pesticides within a decade, while ensuring food productivity, resilient land management, and safe food, air, and water. (Beyond Pesticides, April 15, 2022) The current issue of Pesticides and You, RETROSPECTIVE 2021: A Call to Urgent Action, is a look at a year of science, policy, and advocacy that informs both the existential problems that the U.S. and the world are facing due to toxic pesticide dependency, and solutions that can be adopted now. The information in this issue captures the body of science that empowers action at the local, state, and federal level, and provides a framework for challenging toxic pesticide use and putting alternatives in place. The issue finds that 2021 was a pivotal year in both defining the problem and advancing the solution. This year in review is divided into nine sections that provide an accounting of scientific findings documenting serious pesticide-induced health and environmental effects, disproportionate risk to people of color and those with preexisting conditions, regulatory failures, at the same time […]

(Beyond Pesticides, April 14, 2022) Over the last century, cities across the world have engaged in a “war on rats” that has failed to achieve meaningful results, and should consider a new paradigm for rodent management, according to a review of relevant literature published in Frontiers in Ecology and Evolution last month. As awareness regarding the widespread dangers of commonly used rodenticides increases, and states like California begin to rein in their use, the importance of alternative management approaches has grown. Reviewing over 100 studies on municipal rat management, the authors outline a path forward that embraces a systems approach and calls for a change in public expectations. Since the early 1900s, municipal rat management has primarily focused on killing rats and removing their food, water and harborage, but data available on the efficacy of this approach is sparse. Successful programs, according to the literature, are often grant funded and time limited, or employ such substantial amounts of rodenticide that it carries significant risks regarding secondary poisoning of people and nontarget species. Failures consistently note the ephemeral nature of rodent reductions. A 1909 study referenced in the review, from which the authors indicate much of present-day rodent management is based, […]

(Beyond Pesticides, April 13, 2022) The combined effects of insect pollination and natural pest control provided by birds synergize to improve yields and income for coffee farmers, finds research published this month in the journal PNAS. Ecosystem services – the positive benefits provided by ecosystems, wildlife, and their natural processes – underpin agricultural production, but are often analyzed in silos, on a case by case basis in the scientific literature. The current research finds that the quantitative benefits of ecosystem services can be greater when considering their interactive effects. “Until now, researchers have typically calculated the benefits of nature separately, and then simply added them up,” says lead author Alejandra MartĂnez-Salinas, PhD of Costa Rica’s Tropical Agricultural Research and Higher Education Center (CATIE). “But nature is an interacting system, full of important synergies and trade-offs. We show the ecological and economic importance of these interactions, in one of the first experiments at realistic scales in actual farms.”  Researchers based their experiment in Costa Rica, working with 30 shade grown coffee farms owned by small landholders. Eight coffee plants on each farm were selected for the study. Pest control services provided by birds were assessed using a 20mm mesh screen that excludes […]

(Beyond Pesticides, April 11, 2022) As the U.S. encourages the spread of chemical-intensive, industrialized agriculture, local farmers are increasingly pressured into giving up traditional agricultural practices in favor of monocultures to increase the demand  for agrichemical pesticides and fertilizers worldwide. This policy is promoted by the industry with vested economic interests as good for the U.S. economy, but it is not good for either planetary health or global food security. Instead, U.S. foreign aid agencies, through the U.S. Agency for International Development (USAID) and other agencies, should be supporting traditional practices and organic agriculture. Tell Congress and U.S. AID to support aid that promotes traditional and organic agriculture. Industrial agriculture depends on monoculture—growing single crops that can be easily planted, fertilized, treated with pesticides, and harvested—especially on large-scale, mechanized farms. In spite of the perceived advantages of monoculture, however, it is a significant contributor to biodiversity loss and pollinator decline. Loss of biodiversity feeds the pesticide treadmill by removing predators and parasites who keep crop-feeding insects below damaging levels. The vast majority of crop plants depend on pollinators. Traditional agriculture, like organic agriculture, depends on interacting species. Most organic agriculture resembles monoculture piecewise, but integrates cover crops, hedgerows and other […]

(Beyond Pesticides, April 4, 2022) Recent actions by the U.S. Environmental Protection Agency (EPA) highlight the urgent need to prevent pesticides from further endangering crucial pollinators, including birds, bees, and bats. Tell EPA To Ban Neonics and Protect Against Other Threats to Pollinators. Tell Congress To Insist that EPA Does Its Job. Despite EPA’s own findings of evidence of serious threats posed by neonicotinoid (neonic) pesticides 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 and it appears that the agency is prepared to finalize these registrations late in 2022. This would, barring further action, extend the use of these harmful compounds for 15 years. Now is the time to let EPA know that continued use of neonicotinoids is unacceptable. Furthermore, building on a history of unenforceable and impractical pesticide label restrictions resulting in EPA findings of ludicrously small or no risk, the agency spun its approval of the continued use of the deadly organophosphate insecticide malathion as “protecting threatened and endangered species.” As the nation and world sit on the brink of biodiversity collapse and deadly pesticide-induced diseases, EPA actions continue to protect pesticide […]

(Beyond Pesticides, March 31, 2022) Composts produced using traditional ecological knowledge create healthier, more fertile soil than industrial, chemical-based fertilizers, according to the findings of a recent study published in PLOS Sustainability and Transformation. As the dangers posed by industrial agriculture become increasingly apparent, organic and traditional practices show a time-tested path toward a sustainable farming future. According to study author Seema Sharma, PhD, “The research was already there because the ancient people did their research long ago,” she said to EOS. “But when it comes to the scientific community, you need research that is in a peer-reviewed journal and then finally verified.” The study focuses its comparison within the Kachchh district, a semi-arid farming area of Western India that experiences erratic rainfall and has higher salt levels in its soils than much of the rest of the country. Twenty farms were chosen based on their fertilizer management practices, split between farmers employing traditional composting techniques and those using chemical fertilizers. For the chemical farms, an initial application of animal-based manure was applied, and synthetic sources of nitrogen (urea) and phosphorus (ammonium phosphate) were then spread as a top dressing at a rate of roughly 60kg (132lbs)/ha approximately 20 days […]

(Beyond Pesticides, March 16, 2022) Pest damaged plants release volatile chemical “scents” that alert other nearby plants of potential predators and give them time to prepare their defenses, according to research recently published in Plant Physiology by researchers at Tokyo University of Science. The findings have important implications for agriculture, including new practices that utilize this novel process. “The effective use of plants’ natural survival strategies in production systems will bring us closer to the realization of a sustainable society that simultaneously solves environmental and food problems,” says study coauthor Gen-ichiro Arimura, PhD. Budding research conducted since the turn of the century has discovered and confirmed that plants can communicate through specific volatile organic compounds (VOCs).  These compounds, referred to by researchers as “infochemicals,” can act as airborne signals that an herbivore danger is in the vicinity. Not only can plants within the same species communicate, there is evidence that plants will react to infochemicals produced by different species the other plant cannot produce, and may never have encountered. A recent experiment found, for instance, that soybean plants grown near mint are better able to withstand pest pressure by “eavesdropping” on VOCs produced by mint. Likewise, corn and tomato plants […]

(Beyond Pesticides, March 15, 2022) Adding animal diversity to rice paddy farms reduces weed pressure, increases food production, and makes fertilizer use more efficient, according to a study published late last month in the journal eLife. As chemical-dependent, industrialized agriculture has spread across the world, local farmers are increasingly pressured into eschewing traditional agricultural practices in favor of monocultures in an attempt to meet the demands of global markets. This one-size-fits-all approach oversimplifies the interdependency within ecosystems, failing to incorporate the complexity of nature that many traditional and organic practices embrace. As the present study shows, research and investment into systems that promote natural diversity can provide insights that allow these approaches to leapfrog the chemical-dependent, monoculture paradigm of industrial agriculture. Rice paddy fields are intentionally flooded, and crops are often grown in shallow water. In industrialized fields, monocultures of rice are planted out, and fertilizers and weed killers are applied at regular intervals. However, many traditional rice farmers around the world integrate aquatic animals into their paddies. In the present experiment, researchers conducted a 4-year long evaluation comparing the benefits of monoculture production against co-cultures of rice and aquatic animals. Co-culturing animals and rice differs slightly from traditional practices […]

(Beyond Pesticides, March 14, 2022) The National Organic Standards Board (NOSB) is receiving written comments from the public through April 1. This precedes the upcoming public hearing on April 19 and 21—concerning how organic food is produced. Written comments must be submitted through Regulations.gov. For details on the all the issues of importance to organic integrity, please see Beyond Pesticides’ Keeping Organic Strong webpage. The NOSB is responsible for guiding the U.S. Department of Agriculture (USDA) in its administration of the Organic Foods Production Act (OFPA), including the materials allowed to be used in organic production and handling. The role of the NOSB is especially important as we depend on organic production to protect our ecosystem, mitigate climate change, and enhance our health The NOSB plays an important role in bringing the views of organic producers and consumers to bear on USDA, which is not always in sync with organic principles. There are many important issues on the NOSB agenda this Spring. For a complete discussion, see Keeping Organic Strong and the Spring 2022 issues page. Here are some high priority issues for us: Cetylpyridinium chloride (CPC) is a quaternary ammonium compound (quat or QAC) that is being petitioned for […]

(Beyond Pesticides, March 8, 2022) A silver lining has emerged from the past two devastating Covid years, according to Civil Eats. A large California school district has used pandemic changes — in the regulatory schema of the federal and state governments, in supply chain function, and in available funding — to catalyze the transition to organic food in school-based feeding programs. For the past decade or so, U.S. school districts have, here and there, been moving gradually in this direction. The West Contra Costa Unified School District (WWCUSD) is robustly making the transition to organic, in no small part through its collaboration with Conscious Kitchen, a local nonprofit that seeks to “break the cycle of conventional, packaged, overly processed food, [and] transitioning to meals based on five foundational attributes: fresh, local, organic, seasonal and nutritious.” Beyond Pesticides has long pointed to the importance of shifting school-based meals to organic for multiple reasons, but centrally, because the pesticides with which conventional food is generally contaminated have outsized health and developmental impacts on children. The WWCUSD, which is northeast of San Francisco, boasts 30,000 students — 75% of whom come from low-income households. The district’s food service director, Barbara Jellison, and other food […]

(Beyond Pesticides, March 7, 2022) Contrary to the demands of consumers for hormone-free organic dairy products and the requirements of the Organic Foods Production Act (OFPA), the U.S. Department of Agriculture (USDA) will allow continued use of the synthetic hormone oxytocin in organic dairy production. The National Organic Standards Board (NOSB) voted unanimously in 2017 to reject the use of the synthetic hormone oxytocin in livestock production. Since administration of oxytocin has been linked to a range of serious health problems and early onset puberty, autism, and psychiatric disorders, it is important to avoid residues in food that may cause a hormone imbalance in food consumers. Tell USDA Secretary Vilsack to reverse the decision to allow oxytocin in organic dairy. Tell Congress that greater oversight is needed to ensure that USDA upholds the Organic Foods Production Act. Substances on the National List are reconsidered every five years to determine whether they still meet criteria in OFPA—that is, that their use is (1) not harmful to human health or the environment, (2) necessary for organic production, and (3) consistent with organic practices. In the case of oxytocin, a hormone involved in the milk “let-down” reflex, there is longstanding concern that misuse […]

(Beyond Pesticides, March 4, 2022) An article in My London reported by Finn Byrne, finds labeling on conventionally grown fruits and vegetables marked as non-vegan. The non-vegan label shocked many shoppers who buy the produce with chemical-intensive practices, as fruits and vegetables are inherently vegan. However, pesticides used in the production of fruits and vegetables render these foods non-vegan because of the harm that pesticides cause to animals and since a wax coating on fruits and vegetables made of shellac, a resin secreted from female lac beetles and thus non-vegan. Recent studies indicate plant-based diets can mitigate excessive pesticide use and exposure if they are organically grown. However, a plant-based diet reliant on pesticides does little to lessen the health and ecological effects of conventional agriculture. Fungicides are ubiquitous in agricultural and residential settings puts human and animal health at risk. Exposure to fungicides can manifest adverse health effects, including reproductive dysfunction, birth/developmental effects, kidney/liver damage, and cancer. Several researchers find that fungicide use promotes more drug-resistant fungal infections in humans as these fungicides are structurally similar to medical antifungal medications. After investigating fruits and vegetables at various United Kingdom (UK) grocery stores (i.e., Tesco, Morrisons, and Marks and Spencer), the report finds fungicides imazalil and propiconazole present […]

(Beyond Pesticides, February 16, 2022) Pesticide exposure disturbs the gut microbiome of social bees, leading to a range of alterations that could affect fitness in the wild, finds a major literature review recently published by researchers at the University of Ottawa, Canada. With research on bee gut microbiomes is still in its infancy, the review provides a centralized overview of data collected to date, and highlights areas for further research to fill in remaining knowledge gaps. “Social bees have gut microbiotas that contribute to their health, just like we (humans) do,” said Michelle Hotchkiss, a PhD candidate in the Faculty of Science at the University of Ottawa. “Further research on the interactions between pesticides, bee gut microbiotas, and bee hosts will help us better understand how pesticides affect bee health and performance.” To conduct their review, scientists collected research relating to bee gut over the last 50 years. “The earliest studies we found were published in the 1970s and the most recent ones in 2020,” said Dr. Hotchkiss. “We summarized what methods were used to collect data, including which bee hosts and pesticides were examined. To summarize how the abundances of core microbes changed after pesticide exposure, we looked at […]

(Beyond Pesticides, February 14, 2022) When your food scraps are sent to the landfill, their anaerobic decomposition releases methane, a greenhouse gas with 84 times the global warming potential of carbon dioxide over its first 20 years in the atmosphere. By composting those scraps instead, you not only reduce methane emissions, but also support organic practices that eliminate other greenhouse gases, like nitrogen fertilizer. California’s SB 1383, signed into law in 2016, now requires individuals and businesses to separate food waste from trash. While individuals and businesses can compost their own food waste, local agencies also facilitate the process by providing separate bins for organic materials, including food waste, lawn and garden trimmings, and paper. The law also provides a means for collecting and distributing surplus edible food. Tell your Governor and state legislators to follow the lead of California in fighting climate change with composting. If you live in California, thank your legislators and Governor for passing SB 1383. Methane comprises 16% of greenhouse gas (GHG) emissions, but due to its greater warming potential, it affects climate change at least as much as carbon dioxide (CO2). Agriculture, energy production, and landfills are among the greatest sources of methane emissions. […]

(Beyond Pesticides, February 2, 2022) Over the last 40 years, dragonfly species have declined in the United States due to an interplay between increasing pesticide use and rising temperatures from climate change, according to a recent study published in Ecological Applications by researchers at the University of Ottawa. The study highlights the need to evaluate and address insect declines on a macroecological scale, as human activities over the last several decades have become key drivers of Earth system processes in the Anthropocene era. At this macroecological level, the authors call for analysis of multiple interacting stressors, including land use change, pesticide applications, precipitation, and temperature. To conduct their macro-scale analysis, researchers used a dataset consisting of over 200,000 observation records for dragonflies in the U.S since 1980. Then, U.S. land was subdivided into 100 x 100 km (62 x 62 mile) quadrants, and observation records plotted and refined to ensure that at least 15 species were observed in each quadrant used. Datasets were also obtained on land use changes (via HYDE dataset), pesticide applications (via U.S. Geological Survey), and changes in precipitation and temperature (via Climatic Research Unit). Review of the data found that out of 104 dragonfly species, each […]

(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, January 27, 2022) Wildlife officials in Florida have resorted to supplementing starving manatees with cabbage and lettuce in an attempt to keep their rapidly dwindling populations alive. Massive Red Tides exacerbated by runoff from urban and agricultural pollution have directly killed off dozens of manatees over the last several years, but the indirect effects of these harmful algae blooms have been most catastrophic, resulting in significant loss of the seagrass beds upon which manatees rely. While Florida Governor Ron DeSantis has announced plans to spend $481 million on water quality improvement projects, conservationists note that the funds are primarily directed toward point source wastewater treatment, and more is needed to address nonpoint source herbicide and fertilizer runoff from agricultural, and urban and suburban yards. Florida manatees, a subspecies of the West Indian manatee, can live as long as 60 years old, weigh up to 1,200 lbs, and have no natural predators within their range. The biggest threat to these peaceful marine mammals is human activity and environmental stressors. Unfortunately, the former is well-known to exacerbate the latter. Humans harm manatees primarily through boat strikes, but the animals can also die from eating or becoming entangled in fishing equipment, […]
