Study Finds Synergism between Neonicotinoids and Parasites Leads to 70% Declines in Honey Bee Survival

Tuesday, June 25th, 2019

(Beyond Pesticides, June 24, 2019) A study finds that the interaction of a common honey bee parasite with neonicotinoid insecticides causes 70% reductions in overwintering honey bee survival. These results help to explain the unsustainable honey bee colony losses observed in recent decades. Neonicotinoids (neonics) are a class of insecticides that share a common mode of action that affect the central nervous system of insects. Studies show that neonicotinic residues accumulate in pollen and nectar of treated plants, and, given their widespread use and known toxic effects, there is major concern that neonics play a major contributing role in pollinator declines. In the early 2000s, Colony Collapse Disorder (CCD) brought national attention to increased honey bee colony losses. During the same period that CCD and colony losses spiked, neonic prevalence skyrocketed, in large part due to the introduction of seed-delivered technologies. As of 2011, 34-44% of soybeans and 79-100% of maize hectares were preemptively treated with neonics. While CCD prevalence has decreased, colony loss rates (and systemic insecticide use) remain high. A 2018 national survey indicates that U.S. beekeepers currently experience an average annual colony mortality rate of 30.7%, double the pre-CCD baseline of 15% losses. In the present study, […]

Ask Congress to Stop EPA Actions that Threaten Bees

Monday, June 24th, 2019

(Beyond Pesticides, June 24, 2019) During “Pollinator Week,” last week, the U.S. Environmental Protection Agency betrayed its responsibility to protect the environment and approved “emergency” uses of sulfoxaflor, a bee-toxic insecticide, in 11 states on millions of acres of crops that are attractive to bees. Sulfoxaflor is functionally identical to the neonicotinoid class of systemic pesticides, which are readily absorbed and translocated into the plant tissues, including its pollen and nectar. These insecticides are substantial contributors to the dramatic decline of pollinators and what is now recognized as a global insect apocalypse. Ask Your Elected Members of Congress to Tell EPA that Its Actions Are Unacceptable and Must Be Reversed In 2015, beekeepers sued to suspend the use of sulfoxaflor. A year later, in 2016, the chemical’s registration was amended with the specific exclusion of crops such as cotton and sorghum that attract bees, essentially acting as an aromatic draw to poison. However, EPA regularly utilizes the “emergency exemption” rule under Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to circumvent these restrictions. The Center for Biological Diversity reports, “Ten of the 11 states have been granted the approvals for at least four consecutive years for the same ’emergency.’ Five have […]

Customers Demand Kroger Stop Selling Food Grown with Bee-killing Pesticides

Thursday, June 20th, 2019

(Beyond Pesticides, June 19, 2019) To mark National Pollinator Week (June 17-23), more than 10,000 people across the country are joining to demand that Kroger (NYSE: KR) help stop the extreme decline of pollinators. Customers are delivering letters to stores asking the nation’s largest conventional grocery store to eliminate pollinator-toxic pesticides from its food supply chain and increase domestic organic food offerings to help stop the catastrophic decline of pollinators and other insects. Pollinators and other insects could go extinct within a century, threatening a “catastrophic collapse of nature’s ecosystems,” the first comprehensive global meta-analysis of insect decline states. This is largely due to the widespread use of neonicotinoids and other toxic insecticides in industrial agriculture. “Systemic neonicotinoid insecticides and the broad range of pesticides that harm people and pollinators have no place in our food supply,” said Drew Toher, community resource and policy director at Beyond Pesticides. “Kroger customers are asking the company to be part of the solution to the pollinator crisis by eliminating hazardous pesticides and expanding organic options.” “To avoid the â€bee apocalypse’ it is critical that Kroger immediately commit to stop selling food with pollinator-toxic pesticides,” said Tiffany Finck-Haynes, pesticides and pollinators program manager at […]

Loophole “Emergency” Use of Bee-Toxic Sulfoxaflor Approved During Pollinator Week

Wednesday, June 19th, 2019

(Beyond Pesticides, June 19, 2019) On June 17, 2019, the Environmental Protection Agency (EPA) once again approved “emergency” uses of sulfoxaflor, a bee-toxic insecticide, on millions of acres of crops that are attractive to bees. Sulfoxaflor is functionally identical to the neonicotinoid class of systemic pesticides, which are readily absorbed and translocated by the plant, including its pollen and nectar.

Industrial Agriculture Practices Contribute to the Insect Apocalypse

Tuesday, June 18th, 2019

(Beyond Pesticides, June 18, 2019) As the New York Times wrote in November 2018, “The Insect Apocalypse is Here.” But can we reverse it? Pollinator Week this year is overshadowed by a greater, all-encompassing crisis that spans the entire insect world. Scientists and researchers have identified three broad contributors to the crisis: pesticide use, habitat destruction, and climate change. It is evident that multi-national agrichemical industries, companies like Bayer Monsanto, DowDupont, Syngenta, and the umbrella organization Croplife, that pervade our food system share much of the blame. But through public pressure and consumer choice, we can shift towards alternative products and practices, improve biodiversity, and begin to repair the damage done by industrial agriculture. Pesticide Use Industrial agricultural often places pesticide use as the first tool in the toolbox of possible fixes to pest problems. This leads to a range of deleterious impacts both up and down the food chain, as both prey and predator succumb to the effects of broad spectrum pesticides. Although it makes common sense that pesticides kill off more than their target insect, the scale of the problem was not realized until a study was published in PLOS One by German researchers. It found, after 27 […]

Be a Hero for Pollinators: Ask Your U.S. Rep to Co-Sponsor the Saving America’s Pollinators Act

Monday, June 17th, 2019

(Beyond Pesticides, June 17, 2019) During Pollinator Week, starting June 17, ask your elected representative in Congress to support pollinators by co-sponsoring Saving America’s Pollinators Act (SAPA). If they are already a cosponsor, use the occasion to thank them for their leadership on this critical issue. With the ongoing saga that is the pollinator crisis, we know who the villains of this story are: Bayer, Syngenta, Croplife America, and other multi-national companies that produce, promote, and protect pollinator-toxic pesticides. But where are the heroes?  Pollinator Week should be a week-long celebration of pollinators and the benefits they provide for people and the environment. Unfortunately, we must point out that the wrongdoers are running the show, and our fluttering friends are disappearing. Chemical corporations use this week to greenwash their products by sponsoring outreach events that completely ignore their role in unprecedented pollinator declines. Don’t be fooled by their disguise. We know that real solutions won’t come from a masked crusader. It won’t be a singular superhero that saves the day. In order to fight the fiendish forces behind the global insect apocalypse, we need a mass mobilization of everyday heroes. Heroes like you can inspire good in your elected officials. Ask your […]

Gear Up for Actions to Protect Pollinators during Pollinator Week, June 17 – 22

Friday, June 14th, 2019

(Beyond Pesticides, June 14, 2019) Next week, June 17–22, marks Pollinator Week 2019, a celebration of the beauty and benefits these critical species provide, but also a call to action to protect pollinators and the natural world. Since United States Senate declared the first Pollinator Week in 2007, nearly every week since there has been new research published linking pesticides to pollinator declines. Yet the companies that produce pollinator-toxic pesticides, like Bayer and Syngenta, make use of this week to excuse their products from any culpability. Instead, they sponsor events and posters, discussing every threat to bees except those posed by the pesticides that make up their bottom line. They are the villains in this story, but there is no superhero in line to save bees, butterflies, birds, and bats.  That’s why it’s up to you, everyday heroes that support protecting pollinators, to alert the public, and inspire good in elected officials. We’ve outlined a week of actions aimed at educating and inspiring action to protect pollinators. Monday Support the New Saving America’s Pollinators Act (SAPA), HR1337. SAPA represents the best opportunity to enact meaningful changes at the federal level that will protect pollinators in the long term. This bill, […]

Researchers Find that Fipronil Causes Transgenerational Toxic Effects

Wednesday, June 12th, 2019

(Beyond Pesticides, June 12, 2019) A new study finds that the widespread insecticide fipronil causes transgenerational toxicity across generations of zebrafish. Fipronil, already known to be highly toxic to aquatic organisms, is now implicated in causing even more damage than previously thought. Even individuals who are not themselves directly exposed are shown to suffer from maternally transmitted toxic effects, including a more than doubled mortality rate. The study, published in Environmental Pollution, tracks hatching, growth, and survival of offspring whose mothers were exposed to fipronil. Researchers exposed a total of 90 adult female zebrafish to environmentally relevant levels of fipronil, within the range of concentrations known to occur in U.S. surface waters, for a period of 28 days. After exposure, females were mated with unexposed males, and their offspring were monitored for hatching, growth, locomotor behavior, heart rate, toxicity and gene expression assays. The conclusion: maternal fipronil exposure induced multiple toxic effects in offspring, including a 30% reduction in hatch rates and, alarmingly, a more than doubling of the offspring mortality rate. Fipronil is a broad-spectrum insecticide widely used for indoor and turf pest control in the U.S., and identified as a ubiquitous contaminant of U.S. surface waters. Fipronil is […]

Take Action: Support Legislation to Protect Pollinators and Ecosystems of National Wildlife Refuges

Monday, June 10th, 2019

(Beyond Pesticides, June 10, 2019) On May 20, U.S. Representative Nydia Velazquez, with 18 co-sponsors, introduced H.R. 2854, “To amend the National Wildlife Refuge System Administration Act of 1966 to prohibit the use of neonicotinoids in a National Wildlife Refuge, and for other purposes.” The bill follows an August 2018 Trump administration announcement that reversed a 2014 U.S. Fish and Wildlife Service (FWS) decision to ban neonicotinoid insecticides on National Wildlife Refuges. Tell members of Congress to protect biodiversity by co-sponsoring HR 2854, which reinstates the 2014 U.S. Fish and Wildlife Service ban on neonicotinoid pesticide use in wildlife refuges that was reversed by the Trump administration in 2018. The administration’s action threatens not only pollinators, but contributes to the attack on biodiversity worldwide. “These pollutants upset the delicate ecosystems of our Wildlife Refuges and they have no place in our public lands,” said Rep.Velázquez. “The ban’s revocation comes as mounting evidence suggests the chemical has damaging environmental effects on bees and other pollinators, undermining the national wildlife system,” she continued. In 2014, FWS announced that all National Wildlife Refuges would join in the phase-out of neonics (while also phasing out genetically engineered crops) by January 2016. FWS “determined that prophylactic use, such as […]

Study Documents Playgrounds Contaminated with Pesticides from Neighboring Chemical-Intensive Ag Land

Friday, June 7th, 2019

(Beyond Pesticides, June 7, 2019) Fruit orchards and vineyards endure some of the most intensive chemical management in all of agriculture. What has not been investigated — until now — is how pesticide drift from such agricultural sites may be affecting nearby public spaces. A recent, first-of-its-kind study out of northern Italy tested 71 public playgrounds near to apple orchards and vineyards in four valleys of the North Tyrol, and finds that 45% are contaminated with a single pesticide, and 24% by more than one. Study authors note that the playground contamination will likely grow worse over the course of the growing season. This would likely amplify the impacts of such chemical trespass on nearby public spaces, never mind the varieties of harm to the sites themselves and the food produced on them. Organic agriculture, of course, remedies all these concerns. The study randomly chose 71 public playgrounds in the four South Tyrolean regions, and analyzed grass samples for potential contamination by 315 different pesticides. Because pesticides applied to agricultural fields, orchards, and vineyards are easily volatized, carried aloft by wind, and/or washed by rain off of the target site, the study also evaluated the impacts of those (and other) factors […]

Take Action: Governors Need to Protect Biodiversity Amid Massive Ecological Decline

Monday, June 3rd, 2019

(Beyond Pesticides, June 3, 2019) As the signs of environmental crises tied to pesticide use escalate and the need for action becomes more urgent, elected officials at the state level must step up to meet the challenges to protect biodiversity and ecosystems essential to life. Waiting on Congress to act allows precious time to pass without critically needed action. The White House fails to acknowledge scientific findings about adverse effects that threaten the sustainability of the environment and human survival. In the last several months, key pieces of science call for dramatic action to eliminate toxic pesticide use and put organic and sustainable practices in place. Ask Your Governor to Issue an Executive Order to Protect the Ecosystems and Biodiversity of Your State. *A 1,500-page assessment from the United Nations Decade on Biodiversity project — the IPBES [Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services] Global Assessment Summary for Policymakers is the most comprehensive look to date at the biodiversity crisis and its implications for human civilization. The findings, approved by an intergovernmental body of 132 member states, including the U.S., provide a devastating assessment of the state of biodiversity and of ecosystem services, which support the delicate balance of nature. *The “crash” of […]

U.S. Fish and Wildlife Service To Consider Monarch Butterfly Endangered Status, Amid Staggering Declines and Threat of Legal Action

Thursday, May 30th, 2019

(Beyond Pesticides, May 30, 2019) Last week, the U.S. Fish and Wildlife Service (FWS) agreed to a 2020 deadline for reaching a decision on protection status for monarch butterflies under the Endangered Species Act. This agreement comes nearly five years after the filing of a petition by conservationists with the Center for Biological Diversity and Center for Food Safety led to the launch of an ongoing status review in 2014. While FWS deliberates, monarch butterflies continue their staggering, decades-long population decline, perhaps for the last of their decades. In the 1990s, the eastern monarch population numbered nearly one billion butterflies, and the western population numbered more than 1.2 million. Last year’s winter counts recorded around 93 million eastern monarchs and fewer than 200,000 western monarchs. That loss is “so staggering that in human-population terms it would be like losing every living person in the United States except those in Florida and Ohio,” Tierra Curry, a senior scientist at the Center for Biological Diversity, said in a statement to Live Science. Recent studies project that if current trends continue, both eastern and western monarch populations face migratory collapse within the next 20 years. FWS is no stranger to the threats facing monarch […]

Fulfilling Legal Settlement with Limited Scope, EPA Cancels Twelve Neonicotinoid Products

Thursday, May 23rd, 2019

(Beyond Pesticides, May 23, 2019) On Monday in the conclusion of a lawsuit, the U.S. Environmental Protection Agency (EPA) announced the final notices of cancellation on the registration of twelve neonicotinoid pesticide products in the Federal Register, each of which contains chlothianidin or thiamathoxam as an active ingredient. The decision to pull these products from the market was required as part of a legal settlement under the Endangered Species Act (ESA) in December 2018 of a successful case, Ellis v. EPA, brought by beekeeper Steve Ellis and a coalition of other beekeepers and environmental groups, including Beyond Pesticides. The case establishes a legal precedent in which the court required action to address the bee-toxic effects of pesticides; however, the effect of the settlement and its impact on overall neonicotinoid and other systemic insecticide use is limited. For all but two of the twelve canceled products, a nearly identical surrogate remains actively registered. Furthermore, the fact remains that there are hundreds more products containing the active ingredients targeted by the lawsuit that have not been removed in any capacity – 106 products containing clothianidin and 95 containing thiamethoxam remain untouched on the market. Breaking down the impacts of the EPA ruling even […]

Trump Officials Propose to Rollback Endangered Species Protection, Break Agreements to Act, and Block Public Review of Decisions

Monday, May 13th, 2019

(Beyond Pesticides, May 13, 2019) The Center for Biological Diversity (CBD) filed four lawsuits last week challenging the Trump administration’s failure to release a trove of documents detailing how the administration is regulating dangerous pesticides, especially as they relate to endangered species. Meanwhile, the U.S. Environmental Protection Agency (EPA) released a set of proposed changes last week that would dramatically reduce protections for the nation’s most endangered plants and animals from pesticides known to harm them. The proposals ignore the real-world, science-based assessments of pesticides’ harms, instead relying on arbitrary industry-created models. The EPA proposals would, for example, gut protections for endangered plants that are pollinated by butterflies and other insects by ignoring the fact that animals routinely move back and forth between agricultural areas and places where endangered species live. The proposals follow intensive efforts by Interior Secretary David Bernhardt to halt federal work on protecting wildlife from pesticides. They were released over a year after a draft biological opinion that was scuttled by the Trump administration found that the loss of pollinators from the insecticide chlorpyrifos would put hundreds of endangered species on a path to extinction. The so-called “refinements” will make it easier for the EPA to claim that pesticides […]

UN Brings Together 145 Experts, 50 Countries, 15,000 Studies, Documents Accelerating Biodiversity Loss Threatening All Life; Ecosystem Protections Urgently Needed

Friday, May 10th, 2019

(Beyond Pesticides, May 10, 2019) The Earth, its natural systems, and as many as a million species are at enormous risk from human activity, says a new assessment from the United Nations Decade on Biodiversity project — the IPBES Global Assessment Summary for Policymakers. The net finding might be expressed as: humans are not immune from the sequelae of biodiversity loss; the ecosystem functions on which human lives depend are in increasingly dire straits. The 1,500-page report, convened by IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services), is the most comprehensive look to date at the biodiversity crisis and its implications for human civilization. A summary of the report’s findings, approved by representatives from the U.S. and other member countries, was released in Paris on May 6; the complete report is expected later in 2019. It is of note and commendable that the summary, though lengthy, is digestible for a lay audience. IPBES is an intergovernmental body of 132 member states, established in 2012, that assesses the state of biodiversity and of the ecosystem services such diversity provides to societies. The group also provides reporting to policymakers on those assessments, and on the dynamics (i.e., causes and impacts) between human […]

Flight Distance of Bumblebees Impaired by Pesticide, Leads to 87% Decline in Accessible Forage Area

Monday, May 6th, 2019

(Beyond Pesticides, May 6, 2019) Beleaguered pollinators deal with a multitude of human-engineered threats: habitat fragmentation and loss via development and agricultural intensification, ecosystems and food sources tainted with toxic synthetic pesticides, and shrinking food sources via habitat and biodiversity loss. Research out of the Imperial College of London shows that such challenges are exacerbated, for bumblebees, by another impact of pesticide exposure — impaired flight endurance and dynamics. Published in the journal Ecology and Evolution in late April, ”Pesticide exposure affects flight dynamics and reduced flight endurance in bumblebees” examines how acute exposure to the neonicotinoid imidacloprid affects the nature of bumblebee foraging flight. The study’s researchers find that worker bumblebees so exposed exhibit significant diminishment of flight endurance — measured as both distance and duration — to approximately one-third of what control workers demonstrate. This new information, aggregated with the many other factors that threaten pollinators, points to the importance of ending the use of chemical controls, such as the neonicotinoid imidacloprid, and transitioning to organic systems of agricultural pest management that do not rely on toxic compounds that harm wildlife, ecosystems, water resources, and humans. Previous research has shown numerous impacts of pesticide exposure on bumblebees, and of neonicotinoid exposure, in […]

Neonicotinoid Insecticide Residues in Food and Water on the Rise, According to USDA Data

Thursday, May 2nd, 2019

(Beyond Pesticides, May 2, 2019) Researchers have documented an increase in food and drinking water residues of neonicotinoids, insecticides linked to breast cancer. Using the Pesticide Data Program (PDP), 1999-2015, of the U.S. Department of Agriculture, the researchers identified near-peak detection frequencies in 2015, after a decline from 2008-2013. Imidacloprid remains the most common neonicotinoid detected across imported commodities, while the neonicotinoids clothianidin, thiamethoxam, acetamiprid, and flonicamid are replacing imidacloprid in domestic production. Authors note that these newer neonicotinoids are potentially more toxic than imidacloprid, raising concerns for understudied human health and environmental impacts. The study, Trends in neonicotinoid pesticide residues in food and water in the United States, 1999–2015, published in the journal Environmental Health, finds the highest detection frequencies for neonicotinoids in drinking water, with 30% of treated drinking water turning out positive for imidacloprid in 2011. Certain fruits and vegetables are also frequently contaminated by neonicotinoids, with detection frequencies ranging from 20% to as high as 57% in the case of imidacloprid on cauliflower. While the study points to specific fruits and vegetables as posing higher risk, the main message reaches beyond individual commodity or individual neonicotinoid results. Authors uncover a systematic increase in detection of neonicotinoid […]

Study Findings on Pollinator Declines: Neonics Increase Honey Bee Vulnerability to Mites

Tuesday, April 30th, 2019

(Beyond Pesticides, April, 30, 2019) According to the latest blog post from pesticide industry propagandist Henry I Miller, the pollinator crisis either a) is not occurring; b) is not a problem; or, c) caused by varroa mites, pathogens, and habitat loss. Notwithstanding outlandish assertions that there is no pollinator crisis, new research is further undermining the long-held industry claim that it is mites and disease alone, and not pesticides that are harming pollinator populations. Published in the journal Scientific Reports by a team of Canadian scientists, this research finds that realistic exposure to neonicotinoid insecticides impairs honey bees ability to groom mites off of their bodies and increases infection with a disease known as deformed wing virus (DWV). “When bee colonies began to collapse years ago, it became clear there wasn’t just one factor involved, so we were interested in whether there was an interaction between two of the main stressors that affect bees: varroa mites and a neurotoxic insecticide, clothianidin,” said Nuria Morfin Ramirez, PhD, at the University of Guelph, Canada. Dr. Ramirez and her team exposed honey bees to a range of different concentrations (low, medium, high) of the neonicotinoid clothianidin, with some bees receiving combined stressors of […]

Planting Clover This Earth Day

Monday, April 22nd, 2019

(Beyond Pesticides, April 22, 2019) This Earth Day, please join us in celebrating, propagating, and educating about a misunderstood and beneficial plant: clover.  Clover: Provides your lawn with enough nitrogen to eliminate any need for ecologically hazardous synthetic fertilizers Acts as an important food source for declining pollinator populations Attracts earthworms and other beneficial soil microorganisms Remains green year-round Resists drought Helps your lawn resist disease A little history: “White clover used to be a standard ingredient in every grass seed mix; 75 years ago no one planted a lawn without mixing a little white clover in with the grass seed,” recounts Roger Swain, host of PBS’ The Victory Garden. After World War II, as the middle class grew and moved to suburban communities, chemicals developed during wartime found new uses on U.S. lawns. Chief among them was 2,4-D – an herbicide originally developed with the intent to wipe out potatoes in Germany and rice crops in Japan in a plan to starve the Axis powers into surrender. While 2,4-D was never used for that purpose, its ability to kill broadleaf plants while sparing grass species made it desirable on the farm for removing weeds around crops like wheat, corn, and […]

Neonicotinoid Insecticides Found to Disrupt Insects’ Vision and Flying Ability

Friday, April 19th, 2019

(Beyond Pesticides, April 19, 2019) Flying insects exposed to neonicotinoid insecticides or its breakdown products experience visual impairment and difficulty flying, according to a study published in the journal NeuroToxicology by researchers at the University of Saskatchewan, Canada. While at face value these impacts may sound non-lethal, any loss of fitness in the wild can make flying insects an easier meal for their predators. “Our findings suggest that very low doses of the pesticide or its metabolic products can profoundly and negatively affect motion detection systems that flying insects, such as locusts, grasshoppers and bees, need for survival,” said Jack Gray, PhD, an expert in neural control of animal behavior at the University of Saskatchewan. Researchers used locusts as proxies for other flying insects, as the visual processing in their brains is easy to track in laboratory settings. Moreover, as study co-author Rachel Parkinson notes, “Bees and other flying insects use similar neural mechanisms to process visual motion,” making the implications of this study applicable to a wide range of other airborne insects. And rather than simply focus on the effects of exposure to a single active ingredient, researchers also studied whether its breakdown products (metabolites) resulted in similar impairment. […]

Despite Safety Claims, Insecticide Flupyradifurone Is Bee-Toxic on Its Own and Worse in Combination

Wednesday, April 17th, 2019

(Beyond Pesticides, April 17, 2019)  A neurotoxic pesticide labeled “bee-safe” has been found to be harmful to bees, according to a new study. Flupyradifurone (FPF), the subject of the study, is a novel chemical that was hastily registered in the wake of public awareness about the impact of neonicotinoid insecticides on bees. A systemic insecticide and a nicotinic acetylcholine receptor (nAChR) agonist, it functions in the same way as a neonicotinoid, though it is in the butanolide family. “Lethal and sublethal synergistic effects of a new systemic pesticide, flupyradifurone (Sivanto®), on honeybees,” not only debunks the myth that FPF is safe on its own, it also delves into the FPF’s synergistic effects with a commonly used fungicide propiconazole (PRO). PRO, on its own, has no impact on bee mortality. A rarely studied realm of pesticides, the study defines a synergistic effect as, “when combined exposure to two factors results in an effect that is significantly greater than the sum of individual effects.” Researchers manipulated six healthy honey bee (Apis mellifera ligutica) colonies and observed the impact of varying amounts of pesticide exposure, including both individual and synergistic effects, on behavior and mortality. They recorded data over seasons and between worker […]

Fish and Wildlife Service Sued for Failure to Disclose Use of Bee-Toxic Pesticides and GMO Crops in Wildlife Refuges

Friday, April 12th, 2019

(Beyond Pesticides, April 12, 2019) The Center for Biological Diversity (CBD) announced on April 3 that it is suing the U.S. Fish and Wildlife Service (FWS) for its failure to release public records, despite multiple FOIA (Freedom of Information Act) requests, that would reveal on-the-ground impacts of FWS allowing use of neonicotinoids and genetically engineered (GE) crops in wildlife refuges. Last August, in yet another rollback of protections for wildlife, the environment, and public health, the Trump administration reversed a 2014 FWS decision to ban the use of neonicotinoids and GE crops in National Wildlife Refuges. If successful, the CBE lawsuit, filed in U.S. District Court for the District of Columbia, would compel the agency to provide the requested documents. This would allow the public, largely through the work of NGO (non-governmental organization) watchdogs, such as CBD and Beyond Pesticides, to understand what harms are being caused on the nation’s protected public lands by the administration’s reversal of the 2014 ban. Hannah Connor, a CBD senior attorney, said, “The goal of the lawsuit is to get them to comply with the Freedom of Information Act and produce the records that have been requested. . . . We aren’t asking them to […]
