(Beyond Pesticides, March 25, 2020) The Trump administration’s U.S. Fish and Wildlife Service (USFWS) is moving forward with a proposal to grow genetically engineered crops (GECs) on national wildlife refuges in the Southeast United States. The draft environmental assessment allows wildlife to consume pesticide-laden produce, considers chemical-intensive genetically engineered crops no less damaging to the environment than “non-use of GECs,” and permits and escalation of climate change with toxic pesticide use increases. USFW’s proposal fails to mention the success of organic agriculture and consider it as one of the alternative management strategies. The proposal is up for public comment until April 10, 2020. In 2014, public pressure and lawsuits by environmental groups led to the Obama administration’s decision to phase out GE crops and ban neonicotinoid insecticide use on national wildlife refuges. On August 2, 2018, the Trump administration’s USFWS issued a memorandum that reversed the prohibition. The reversal allows the refuge system to make decisions on the use of GECs and neonics on a case-by-case basis in compliance with the National Environmental Policy Act (NEPA), which is also under attack by the Trump administration. The Center for Biological Diversity, Center for Food Safety, and others quickly challenged the 2018 […]

(Beyond Pesticides, March 24, 2020) Last week, Maryland became the latest state to prohibit use of the brain-damaging insecticide chlorpyrifos, after a measure cleared both the state Senate and House. Although the legislation implements a limited ban that sunsets after four years, advocates consider this action a step in the right direction that will protect the health and safety of Maryland residents. “Even amidst our current public health crisis, the Maryland legislature acted to protect all Marylanders’ health for years to come by banning this toxic pesticide, and we are so grateful,” said Ruth Berlin, Executive Director of the Maryland Pesticide Education Network to WBOC. Chlorpyrifos is an organophosphate insecticide known to inhibit the proper nerve functioning by affecting the enzyme acetylcholine esterase. The impacts of this pesticide are particularly concerning for young children, as research finds that children exposed to high levels of chlorpyrifos had mental development delays, attention problems, attention-deficit/hyperactivity disorder problems, and pervasive developmental disorder problems at three years of age. While Maryland is the fourth state to restrict the use of chlorpyrifos, it is the second to implement these restrictions through legislation. In California, the state Department of Pesticide Regulation is implementing a phase out of […]

(Beyond Pesticides, March 23, 2020) Ignoring science to side with Monsanto/Bayer, EPA has repeatedly failed to assess glyphosate’s impacts on public health and endangered species. Last week, a broad coalition of farmworkers, farmers, and conservationists, filed a federal lawsuit against the Environmental Protection Agency (EPA) over its January 2020 re-approval of the pesticide glyphosate, best known as the active ingredient in Monsanto’s Roundup pesticides. With Center for Food Safety (CFS) serving as legal counsel, the suing organizations are  Beyond Pesticides, the Rural Coalition, Organización en California de Lideres Campesinas, and the Farmworker Association of Florida. While EPA defends glyphosate, juries in several cases have found it to cause cancer, ruling in favor of those impacted by exposure. Glyphosate formulations like Roundup are also well-established as having numerous damaging environmental impacts. After a registration review process spanning over a decade, EPA allowed the continued marketing of the pesticide despite the agency’s failure to fully assess glyphosate’s hormone-disrupting potential or its effects on threatened and endangered species. The review began in 2009, has already taken 11 years, without a full assessment of the widespread harmful impacts on people and the environment in that time period. “EPA’s half-completed, biased, and unlawful approval sacrifices the […]

(Beyond Pesticides, March 19, 2020) As communities across the U.S. brace for an unimaginable health crisis and difficult economic times in the wake of COVID-19, the Beyond Pesticides Hawai’i team has linked arms with Maui’s small farms and community organizations to make sure local farms have the support they need to feed communities and stay in business. The virus is causing shutdowns of everything from farmers markets to restaurants, but community organizers in Maui are making an effort to transform COVID-19 related challenges into a spring board for long-term increase in locally produced, organic food—a sorely needed commodity in Hawai’i.  Hawai’i is the most isolated island chain on the planet. Its fertile soil and climatic conditions coalesce to make Hawai’i potentially a major producer of nutritious food for its residents and for export. However, a complicated plantation history and off-island investment influence has skewed the economy toward tourism and development. The current stark reality is that 85-90% of Hawai’i’s food is imported, making the islands particularly vulnerable to disasters and global events that might disrupt the economy or infrastructure.  COVID-19 is now disrupting the economy and local infrastructure of Maui. Farmers markets and other public gatherings have closed. Tourism is […]

(Beyond Pesticides, March 18, 2020) Freshwater habitats are threatened now—more than ever—by the adverse effects of pesticide pollution, according to a report published in Scientific Reports by a collaborative research team from the Helmholtz Centre for Environmental Research (UFZ) and the Kenya-based International Centre of Insect Physiology and Ecology (ICIPE). Pesticide pollution, attributed to runoff from agricultural farms, indirectly increased the rate of the tropical disease schistosomiasis, which infects over 280 million people (2018). This research underlines the range of uncertainties that exist as a result of pesticide contamination, making it critically important that subtropical areas where this disease threat exists move toward organic and pesticide-free approaches.  Increased prevalence of this disease is devastating to socioeconomic development in affected regions, as life expectancy, employment rate, and gross domestic product (GDP) decreases. Schistosomiasis (snail fever), or bilharzia, is a tropical disease caused by parasitic flatworms (trematodes) in the genus Schistosoma and transmitted via freshwater snail (genus Biomphalaria) to its definitive human host. Freshwater snails act as a vector for schistosomiasis as they play a vital role in the lifecycle of the parasitic flatworm. Professor Matthias Liess (Ph.D.), Head of the Department of System Ecotoxicology at the UFZ, and his research team investigated pesticide pollution’s […]

(Beyond Pesticides, March 13, 2020) The European Commission’s proposed (post-2020) Common Agricultural Policy (CAP) is a failure and must be dramatically changed to embrace organic practices and support small farmers, according to a paper written by 21 scientists and published in the British Ecological Society’s journal, People and Nature. The authors point to provisions that permit anemic implementation of critical sustainability goals, and say that as it stands, the CAP fails “with respect to biodiversity, climate, soil, [and] land degradation as well as socio‐economic challenges.” The authors call on the European Parliament, Council, and Commission to adopt 10 urgent action points that advance a goal that “all CAP elements, without exception, should be aligned with the principles of sustainability, multi‐functionality and public payments for public goods.” The paper’s authors say that the CAP continues, in fact, to support practices that exacerbate the climate emergency, soil erosion, land degradation, and biodiversity loss, and fails to fund initiatives that could address climate and other critical issues. Happening concurrently with the CAP is development of the European Commission’s (EC’s) “European Green Deal,” which the EC describes as a roadmap for making the EU’s economy sustainable, and making Europe the first climate-neutral continent by 2050.

(Beyond Pesticides, March 12, 2020) Farmworkers walked out of an orchard in Sunnyside, Washington on Friday, March 6 to demand improved working conditions. Over a dozen individuals cited unacceptable issues, such as toxic pesticide exposure, unfair wages, and lack of paid breaks. Their employer, Evans Fruit, owns and farms over 8,000 acres in the state. These workers represent the ongoing fight against injustice perpetuated by the chemical-intensive agriculture industry. Evans Fruit workers said the company gives insufficient protective gear and training before requiring workers to spray pesticides for most of their 12 to 15-hour workdays. Jorge de los Santos, who has worked for Evans Fruit for five years, told the Yakima Herald, “My eyes (were) constantly irritating me.” “All we’re asking for is for fair wages and fair (working conditions),” said Rene Isidoro, another farmworker. Evans Fruit declined to comment, but worker representatives said the company has been unwilling to negotiate. “The company basically said it was their way or the highway,” said United Farm Workers (UFW) of America Pacific Northwest coordinator Victoria Ruddy. “We are good workers, responsible workers,” Ms. Isidoro said, “We like the work we do. We want to do better in our work. We’re here simply […]

(Beyond Pesticides, March 11, 2020) Worldwide, organic farming practices quadrupled from 2000 to 2018, with over 180 countries leading a global transition to organic agriculture. Newly published global survey data by the Research Institute of Organic Agriculture (FiBL) and International Federation of Organic Agriculture Movements – Organics International (IFOAM) reveal global organic agriculture to be at an all-time high, with 71.5 million hectares (mha) of farmland in production. Organic agriculture’s rise in popularity makes important progress toward the United Nations Sustainable Development Goals, as organic agriculture is essential for a sustainable future; it is a solution to the global food crisis and eliminating the health risks engendered by chemical-intensive farming. According to Monica Rubiolo, PhD of the Swiss State Secretariat for Economic Affairs (SECO), “Access to quality data on organic farming not only helps to measure success toward achieving the Sustainable Development Goals but also to orient decision-makers and other stakeholders along the whole value chain.” In a period of rapid population growth, a climate crisis, environmental degradation, and high energy costs, organic farming addresses human health, environment, and socioeconomic concerns. Organically managed farmland increased by a total of 2 mha (2.9%), in all continents, between 2017 and 2018. Australia has […]

UPDATE: The same day Beyond Pesticides published this piece, Gulbrandsen Chemicals announced it would drop its effort to produce pentachlorophenol in Orangeburg, SC, according to The State newspaper. (Beyond Pesticides, March 10, 2020) Orangeburg, South Carolina may be the last place in the world to produce one of the most toxic pesticides known to humanity, pentachlorphenol. Despite a global ban on “penta” in 2016, in force in 186 countries, the United States has continued to import and use this hazardous wood preservative on telephone poles and railroad ties throughout the country. Now, with Mexico set to close one of the last production plants in the world, Gulbrandsen Chemicals Inc. wants to make Orangeburg, a majority black community with a population three times the U.S. poverty rate, the new epicenter for penta manufacturing. Overview and History Penta is used to pressure treat wood, with the aim of prolonging its use in utility poles and railroad ties. Beyond Pesticides has sounded the alarm on penta and other wood preservatives for over 20 years, starting with the reports Pole Pollution and Poison Poles, which outlined the science on the hazards and and alternatives to preservative-coated utility poles. Penta is a particularly concerning wood […]

(Beyond Pesticides, March 6, 2020) Scientists from Imperial College London have just published their recent research on impacts of pesticides on larval bumblebees exposed through neonicotinoid-contaminated food sources. Many studies have looked at the devastating impacts of pesticides on adult insects, including pollinators — and bees, in particular. This research, however, examines how exposure to the neonicotinoid imidacloprid, through consumption of contaminated nectar and pollen during the larval stage, affects bumblebees (Bombus terrestris audax). It finds that these exposures cause abnormal brain growth in some parts of the bees’ brains, and significantly impairs learning ability compared to bees who were not exposed. Advocates maintain that neonicotinoid pesticides should be banned for their widespread and severe damage to insects and the environment broadly, in addition to human health concerns. Neonicotinoids (neonics) comprise a class of pesticide used intensively in many parts of the world. They may be applied to plant foliage, or directly to soils as a drench, but the predominant use is for seed treatment. These pesticides are banned or restricted in some places, including in the European Union, France, Germany, and Italy; some states have also worked to rein in their use. Previous research out of Harvard University has […]

Experimental ponds in Gault Nature Reserve. Photo credit: Vincent Fugère (Beyond Pesticides, March 5, 2020) A new study conducted by researchers at McGill University investigated phytoplankton (microscopic algae) response and resilience to Roundup exposure. “Community rescue in experimental phytoplankton communities facing severe herbicide pollution” was published in Nature Ecology & Evolution. Researchers found that algae can develop resistance to contamination, but surviving phytoplankton communities are much less diverse. Diversity loss is cause for concern as it could hinder adaptation to other potential stressors, such as climate change.  Using experimental ponds, researchers first exposed some phytoplankton communities to low levels of Roundup over time, then dosed the ponds with a lethal amount.  Groups that had been given low doses survived the lethal phase whereas unpolluted, control ponds did not. Researchers observed “community rescue,” where genetic changes avert population collapse in a lethal environment. In fact, glyphosate eventually became a fertilizer in resistant ponds as it is a significant source of phosphorus. Other studies, too, have noted that phosphorous loading is an overlooked impact of glyphosate contamination. Phytoplankton matter because their disruption can cause a trophic cascade and impact other organisms. “These tiny species at the bottom of the food chain play […]

  (Beyond Pesticides, March 4, 2020) California produces the most food of any state in the U.S. – more than half of all domestic fruits and vegetables – but only 4% of its agriculture is organic. After releasing a report on the benefits of organic agriculture last year, the California Certified Organic Farmers (CCOF) Foundation is continuing to offer a “Roadmap to an Organic California” with an extensive policy report. The document proposes a wealth of concrete strategies for California lawmakers to employ. Organic agriculture, the authors skillfully reason, can respond to three pressing issues in California: climate resilience, economic security, and health equity. Additionally, the report highlights the need for focus on organic integrity in order to sustain positive change away from toxic practices. Climate Resilience The climate crisis is already impacting California; heat waves, droughts, and devastating wildfires are occurring more frequently and severely. Organic agriculture is often forgotten as politicians consider solutions. CCOF proposes that policy makers help combat the climate crisis through supporting healthy, carbon-sequestering soil practices that are federally mandated in organic agriculture. In addition to building farm resilience, healthy soil secures some of the state’s water supply. Because it is porous and sponge-like, well-maintained […]

(Beyond Pesticides, March 3, 2020) Pregnant mothers living in areas where carcinogenic pesticides have been used are at increased risk of their child developing an acute form of leukemia, according to research published last month in the International Journal of Hygiene and Environmental Health by researchers at the University of California, Los Angeles. The findings are based on a review of pesticide use data in rural, agricultural areas of California, where many minority, low-income and farmworking communities live. Under current laws, the U.S. Environmental Protection Agency (EPA) permits the use of cancer-causing pesticides with an expectation that a certain number of cancers (anywhere from 1 in 1,000 to 1 in 1,000,000, based on the pesticide in question) should be considered ‘acceptable risk.’ While past studies have shown similar connections between pesticide exposure in the womb and the development of childhood cancer, this is one of the first to utilize geographic information systems (GIS) data, rather than parental interviews on past exposures. Researchers used California public records of cancer incidence from 1998-2011, alongside statewide pesticide use reports (California is the only state to make this information publicly accessible and searchable). A list of 65 pesticides were investigated for their specific connection […]

(Beyond Pesticides, March 2, 2020) Deadline today! Tell EPA to Ban Atrazine; Protect Children and Frogs from this Endocrine Disrupting Pesticide. Atrazine, the second most-used herbicide in the U.S., is an insidious poison. Atrazine is known for producing developmental abnormalities in frogs. It also affects the endocrine system and reproductive biology of humans. In addition to its agricultural uses on corn, sorghum, and sugar cane, atrazine is also used on home lawns, school grounds, and parks, where exposure to children is common. Nontoxic alternatives are available for all of these uses. Act today, March 2. Sign the petition demanding that EPA ban atrazine and its cousins simazine and propazine. Act today! Beyond Pesticides will submit comments: Docket: EPA-HQ-OPP-2017-0750 (FRL-10002-92) Petition to EPA’s Office of Pesticide Programs: We have serious concerns with the proposed interim decisions on reregistration of three triazine pesticides: atrazine, simazine, and propazine. These triazines are highly mobile and persistent in the environment and have been linked to numerous adverse health and environmental effects which have motivated numerous public interest campaigns to ban their use in the U.S. as well as in Europe. The Draft Ecological Risk Assessments for the Registration Review of Atrazine, Simazine, and Propazine dated October 5, 2016 […]

(Beyond Pesticides, February 28, 2020) State legislators in Boise, Idaho have advanced House Bill 487, An Act Relating to Pesticides and Chemigation, out of the House Agricultural Affairs Committee. If passed, the statutory alterations in this bill would, according to the Idaho Statesman, loosen some rules on aerial application by crop-dusting airplanes, and reduce state agricultural investigators’ ability to regulate the spraying of pesticides. The legislation replaces sections of current rules and deletes language regarding drift, including “Chemicals shall not be applied when wind speed favors drift beyond the area intended for treatment or when chemical distribution is adversely affected.” Such changes will exacerbate the already-significant issue of pesticide drift. In an overview of the pesticide dicamba, Beyond Pesticides recently reported on this legislative development, as well as on a precipitating exposure event in an Idaho hops field. Banning of aerial spraying, as has been attempted by some localities, would go a long way toward eliminating the harms of pesticide drift. The only conclusion that can be drawn from this is the following: As the problem of drift grows and farmers’ crops and people are put at risk, this legislation attempts to define away serious problems and eliminate protections. The Idaho […]

(Beyond Pesticides, February 27, 2020) A new report finds that as birds and pollinators continue to decline, and chronic diseases remain on the rise, the global agrichemical industry is raking in billions of dollars from hazardous pesticides that contribute to these crises. A joint investigation from Unearthed and Public Eye finds that 35% of pesticide sales from the largest agrichemical corporations are made from the most toxic pesticides on the market. Pesticide production was a $57.6 billion market in 2018, according to the report. While the profits of the industry are privatized, the public health and environmental effects are broad. Studies conducted over the last decade show that the impacts of hazardous pesticide use dwarf the market for these chemicals. The impact of pesticides on public health results in a drag on the economy. Earlier this year, research from the New York University Grossman School of Medicine found that children’s exposure to organophosphate insecticides was estimated to result in over 26 million lost IQ points and over 110,000 cases of intellectual disability, totaling roughly $735 billion in economic costs each year. A 2019 study from the same scientists determined that endocrine disrupting chemicals, including organophosphates and organochlorine pesticides, were attributable […]

(Beyond Pesticides, February 26, 2020) Agriculture both suffers from the impacts of the climate crisis and contributes significantly to global warming. Representative Chellie Pingree of Maine has introduced H.R. 5861 aimed at achieving a 50% reduction in agricultural emissions by 2030 and net zero emissions by 2040, relative to 2010 levels. Tell Your Congressional Representative to Cosponsor H.R. 5861. July of 2019 was the hottest month ever recorded on Earth. The last time atmospheric carbon dioxide levels were this high (over 415 ppm) was during the Pliocene period – between 5.3 and 2.6 million years ago. We have seen changing precipitation and temperature patterns, resulting in flooding of some agricultural regions and droughts in others, crops and livestock varieties no longer suited to the geographical area where they have been produced, and new problems with insects, weeds, and disease. The Intergovernmental Panel on Climate Change (IPCC) finds that Agriculture, Forestry, and Other Land Use contributes about 23% of total net anthropogenic emissions of greenhouse gases. At the same time, organic production can help reduce greenhouse gas emissions and sequester carbon in the soil. Regenerative organic agriculture reduces emissions of carbon dioxide and nitrous oxide. In nonorganic, chemical-intensive agriculture, greenhouse gas emissions result from the use of nitrogen fertilizer, synthetic herbicides and insecticides, […]

(Beyond Pesticides, February 24, 2019) With more than 90% of total pesticide use deployed in agriculture, organic farming is the keystone solution to the myriad health, environmental, and biodiversity harms of pesticides. A transition to organic and regenerative farming practices — across which there is great overlap — is critical and a tall order, given the entrenched, chemically intensive practices that currently dominate in the U.S. and much of the world. A long-standing research effort by the storied Rodale Institute — the Farming Systems Trial, which began in 1981— is demonstrating that organic agriculture is not only a nontoxic solution, but also, an economically viable one that is critical to a sustainable future. Through the Farming Systems Trial (FST), the Rodale Institute has collected data on crop yields, soil health, energy efficiency, nutrient density of drops, and water use and contamination in organic and conventional systems managed with different levels of tillage. Among the findings of the nearly 40-year research project are these: after a five-year transition period, organic yields are competitive with conventional yields• in drought years, organic yields are as much as 40% higher than conventional yields farm profits are 3–6 times higher for products from organically managed systems […]

(Beyond Pesticides, February 20, 2020) Missouri’s largest peach farm, Bader Farms, is set to receive $265 million in compensation from two multinational agrichemical companies after the companies’ dicamba-based weed killers caused widespread damage to the farm’s fruit trees. Bayer’s Monsanto and BASF were found to be responsible for negligence in the design of their dicamba herbicides, and failure to warn farmers about the dangers of their products. The jury determined that the joint venture between the two companies amounted to a conspiracy to create an “ecological disaster” in the name of profit. In 2015, the U.S. Department of Agriculture (USDA) approved Bayer Monsanto’s release of a new line of genetically engineered (GE) seeds designed to tolerate repeated spraying of dicamba. With glyphosate resistant ‘super-weeds’ widespread and threatening GE farmer’s yields, the company aimed to redeploy dicamba, one of the oldest herbicides in the market, on cotton and soybeans throughout the U.S. Knowing the propensity of dicamba to drift for miles off site, Bayer’s Monsanto promised a new product line with much lower volatility.  But as the company was waiting on approval for this product by the Environmental Protection Agency (EPA), it nonetheless began selling its dicamba-tolerant seeds. This led to […]

(Beyond Pesticides, February 14, 2020) The weed killer dicamba has been blamed for killing or damaging millions of acres of non–genetically modified crops and other plants that have no protection against the compound. Litigation, legislation, and manufacturer machination abound as dicamba damage mounts. The trial in a suit filed in 2016 by a Missouri peach farmer against dicamba manufacturers Bayer and BASF has just begun; an Indiana state laboratory struggles to keep up with demand to evaluate dicamba damage; Idaho lawmakers are poised to weaken rules that protect farmworkers who apply dicamba (and other pesticides) aerially; agricultural officials in Missouri are pressuring the state legislature to increase funding to handle the exploding numbers of dicamba complaints; and Indiana’s legislature is considering two bills aimed at curtailing dicamba drift that kills neighboring crops. This Daily News Blog will round up the plethora of recent news on dicamba — the toxic and destructive culprit behind each of these stories. In the face of the U.S. Environmental Protection Agency’s (EPA) failure to mitigate dicamba hazards, states have been scrambling to enact limits on when and how dicamba can be used, amend buffer zones around application sites, and in some cases, ban its use outright. […]

(Beyond Pesticides, February 13, 2020) Congress unanimously passed the Food Quality Protection Act (FQPA) in 1996 to increase protections for children from pesticide exposure. Unfortunately, according to a new study published in Environmental Health, the law is not being employed by the Environmental Protection Agency (EPA) to its full capacity. For most of the 59 pesticides reviewed by the study, EPA did not apply an additional FQPA safety factor and thereby missed an opportunity to protect children’s health. In fact, FQPA solidified EPA’s reliance on risk assessment calculations and mitigation measures that consistently fall short of adequate levels of protection because of serious data gaps, a failure to consider exposure to mixtures and synergistic effects, and a bias against consideration of alternatives (alternatives assessment)  that show toxic pesticides to be unnecessary.  FQPA establishes a safety standard applied to all food commodities that considers specific risks for infants and children. The law requires EPA to assess the “aggregate risk” (considering exposure from multiple sources) and “cumulative exposure” to pesticides that have a “common mechanism of toxicity.” FQPA mandates “an additional tenfold margin of safety for the pesticide chemical residue and other sources of exposure shall be applied for infants and children […]

(Beyond Pesticides, February 12, 2020) Corteva, a company spun-off from DowDupont, will stop producing chlorpyrifos by the end of this year as a result of declining sales. Despite the move being in the interest of public health, the company is earning little praise from health advocates for what amounts to simply a shrewd financial decision. As news articles on the announcement have noted, Corteva will continue to support Environmental Protection Agency (EPA) registration of chlorpyrifos, which allows generic manufacturers to continue to sell this brain-damaging chemical. “Other people are going to continue to profit from harming children,” said Marisa Ordonia, an attorney with the group EarthJustice to Canada’s National Observer. “It is big that such a major player is saying no, we’re not going to do this any more. It’s a great signal that people don’t want brain-damaging pesticides on their food. But we’re going to continue to keep fighting to make sure children and farmworkers are protected.” At odds is the difference between halting production of chlorpyrifos and cancelling its EPA registration. While Corteva has the ability to voluntarily stop producing its own product, EPA registration permits other generic manufacturers to continue to producing the product. And, over the […]

(Beyond Pesticides, February 11, 2020) A new study, published in the journal Cell Host & Microbe, homes in on the impact of the toxic herbicide atrazine on wasp gut microbiology and pesticide resistance. Intriguingly, researchers found that exposure to atrazine changed the composition of gut bacteria in individual wasps and shifts in gut flora were heritable. This study not only represents one of the first evolutionary studies on symbiont-mediated pesticide resistance, it also provides fodder for future research regarding the implications of exposure to xenobiotics (i.e., chemical substances like toxic pesticides foreign to an organism or ecosystem) for other gut bacteria hosts – such as honey bees and humans. Researchers utilized the hymenopteran insect model Nasonia vitripennis to analyze the effect of subtoxic exposure to atrazine across 36 generations. They reestablished a baseline of toxicity by experimenting with concentrations of atrazine to find the level at which 50% of the population died (LC50). During initial trials, some of the wasps were kept in a germ-free (GF) environment. The authors observed a higher mortality rate among the germ-free population, indicating that gut microbes assist with detoxification.   Early generations of wasps in the study received a field-realistic dose of atrazine (300 […]
