(Beyond Pesticides, September 7, 2012) Yesterday, Beyond Pesticides joined with the Center for Food Safety and the Sierra Club, along with beekeepers from around the country, to file a 60-Day Notice letter with the Environmental Protection Agency (EPA) announcing the intent to jointly sue the agency for Endangered Species Act (ESA) violations. The potential lawsuit highlights EPA’s continuing failure to ensure, through consultation with the U.S. Fish and Wildlife Service, that its numerous product approvals for the neonicotinoid insecticides clothianidin and thiamethoxam are not likely to jeopardize any federally-listed threatened or endangered species. “EPA has failed to uphold the clear standards of the Endangered Species Act,” said Peter Jenkins, attorney at the Center for Food Safety. “By continuing to ignore the growing number of reports and studies demonstrating the risks of neonicotinoids to honey bees and a large number of already threatened and endangered species, the EPA is exposing these already compromised populations to potentially irreversible harm.” The Notice of Intent to Sue follows a legal petition previously filed by several environmental organizations and more than two dozen beekeepers requesting that EPA immediately suspend use of the chemical clothianidin that poses fatal harm to pollinators. While refusing to issue an […]

(Beyond Pesticides, August 28, 2012) New research reveals that bats may be at greater risk from pesticide exposure than previously suspected. When foraging at dusk, bats can be exposed to agricultural chemicals by eating insects recently sprayed with pesticides. A study from the University of Koblenz-Landau in Germany reveals that bats, due to their long life span and tendency to only have one offspring at a time, are particularly sensitive to reproductive effects from pesticides. The study, “Bats at risk? Bat activity and insecticide residue analysis of food items in an apple orchard,” published in Environmental Toxicology and Chemistry, details the health effects of bats foraging on insects in an apple orchard after it was sprayed with the insecticides fenoxycarb and chlorpyrifos. After field applications of the pesticides, scientists measured the remaining chemical residues on flies, moths and spiders for two weeks. The highest residues were recorded on leaf dwelling insects and spiders, while lower contamination was found for flying insects. Based on this data scientists calculated exposure scenarios for different bat species, each with different feeding habits, and found that those which fed off insects from the leaves of fruit trees to be most affected. Researchers indicated that current […]

(Beyond Pesticides, August 24, 2012) U.S. Representative Edward Markey, (D-MA) has sent a letter to the U.S. Environmental Protection Agency (EPA) urging it to investigate a possible link between the use of common pesticides and reductions in honey bee populations. The letter comes as EPA is accepting public comments on a legal petition filed by beekeepers and environmental groups seeking to suspend the use of the neonicotinoid pesticide clothianidin, which has been linked to serious pollinator health concerns. In his letter to the EPA, Rep. Markey asks the agency to respond to questions, including: ӢHas the EPA investigated the impacts of the class of pesticides on honey bees and other pollinators? ӢWhat steps has EPA taken, and what more can the agency do, to limit or restrict the use of these pesticides and reduce the impact on bee populations? ӢWhat steps is the EPA taking to ensure there is sufficient scientific evidence to make informed decisions about the impacts of neonicotinoids on bees and other pollinators? Bee pollination contributes an estimated $15 billion to the agricultural economy. Yet, recent research has found that certain members of a group of related pesticides, known as neonicotinoids, may be jeopardizing bee populations and […]

(Beyond Pesticides, August 9, 2012) On Monday, Beyond Pesticides joined with 23 public health and environmental advocacy groups to send a letter to the U.S Environmental Protection Agency (EPA), urging it to follow through with its original plan to cancel the sale of most toxic rat poisons to residential consumers. In 2008, after over a decade of these products being on the market and widely available to consumers, EPA gave manufactures three years to comply with new risk mitigation requirements for rat poisons. However, the companies Reckitt Benckiser, Liphatech, and Spectrum Brands, producers of d-Con, Rid-a-Rat, and Hot Shot each decided to flout EPA requirements and ignore compliance with the regulations. The letter urges EPA to follow through with its ”˜Notice of Intent to Cancel’. It also instructs the agency to issue an order for emergency suspension of these products under FIFRA section 6(c), based on evidence of imminent hazard to human health and to wildlife. While the cancellation of these products will better safeguard the health of children, pets, and wildlife, EPA’s risk mitigation requirements do not go far enough to ensure protections for vulnerable populations. Children are particularly at risk for exposure because young children sometimes put bait […]

(Beyond Pesticides, August 7, 2012) Like it or not, Monsanto’s genetically modified sweet corn will soon be arriving on grocery store shelves of the world’s largest retailer, Wal-Mart Stores, Inc., and will not be labeled as such. Despite an onslaught of consumer pressure, the company confirmed late last week with the Chicago Tribune that it has no objection to selling the new crop of Monsanto’s genetically modified (GE) sweet corn. Other retailers, including the grocery chains Safeway and Kroger, have not responded on the issue, however Whole Foods, Trader Joes and General Mills have all vowed to not carry or use the GE sweet corn. As the country’s largest grocery retailer, Wal-Mart sells $129 billion worth of food a year, giving it unmatched power in shaping the food supply chain. The GE sweet corn is the first consumer product developed by Monsanto that will go straight from the farm to the consumer’s plate, rather than first being processed into animal feed, sugars, oils, fibers and other ingredients found in a wide variety of conventional food. It is engineered to be resistant to Monsanto’s Roundup herbicide, the active ingredient of which is glyphosate. The product is also designed to produce a […]

(Beyond Pesticides, August 3, 2012) Pesticide manufactures don’t want you to know what’s in your food. According to filings released Tuesday through the office of California’s Secretary of State, chemical company lobby groups have so far spent $750,000 in efforts to block the passage of California’s Prop 37, which would require mandatory labeling on genetically engineered (GE) foods. Opponents of the proposition raised over one million dollars this year for the “Coalition Against the Deceptive Food Labeling Scheme.” Members of this coalition include the ”˜big 6’ chemical companies Monsanto, Bayer, Syngenta, Dow, DuPont, and BASF, which have spent $375,000 alone through their exclusive lobbying group Council for Biotechnology Information. Overlapping ”˜big 6’ membership, the Grocery Manufacturer’s Association (GMA), which also includes the corporations Pepsico Inc., The Coca-Cola Company, and Kelloggs, recently stated in a speech at the American Soybean Association that defeating the California initiative is “the single highest-priority of the GMA this year,” according to a story in The Huffington Post. GMA has also spent $375,000 this year lobbying against Prop 37. “The Big Six chemical & seed companies are working diligently to monopolize the food system at the expense of consumers, farmers and smaller seed companies,” said Philip […]

(Beyond Pesticides, July 30, 2012) The U.S. Environmental Protection Agency (EPA) has opened a 60-day public comment period on the agency’s decision to deny the request by beekeepers to immediately suspend the use of clothianidin, a pesticide that poses harm to pollinators. The legal petition was filed earlier this year by 25 beekeepers and environmental organizations, and cites significant acute and chronic bee kills across the United States linked to neonicotinoid pesticides, particularly clothianidin. On Thursday, Senator Kirsten Gillibrand (D-NY), a member of the Senate Agriculture Committee, called for an expedited review of pesticides that could be inadvertently decimating honey bee populations. The letter is also signed by Senators Patrick Leahy (D-VT) and Sheldon Whitehouse (D-RI). EPA is not expected to complete its review until 2018, and any implementation plans could take years beyond that to complete. Given that Colony Collapse Disorder (CCD) has decreased the U.S. bee population by 30 percent since 2006, Senator Gillibrand is urging a quicker timeframe, asking that it be completed by the end of next year. “Our agriculture industry is vital to the upstate New York’s economy,” Senator Gillibrand said. “Our farmers need honey bees to pollinate our crops and produce. However, certain pesticides […]

(Beyond Pesticides, July 26, 2012) The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) announced this week that it is formally deregulating a line of sugar beets genetically engineered (GE) to resist applications of the herbicide glyphosate. Developed by chemical and seed giant Monsanto Co., the new sugar beets, referred to as “Roundup Ready” (RR), were found by APHIS to not present a risk of becoming a plant pest risk and that they will and are not likely to cause a significant environmental impact. Environmental and public interest advocates, however, point to the fact that the proliferation of glyphosate-tolerant crops has already led to increased pesticide resistance among weeds, and increased pesticide use. The planting of engineered sugar beets brings with it the risk of genetic drift and cross contamination of pollen into non-GE and organic fields growing sugar beets or other related crops, such as table beets, spinach, swiss chard, and quinoa. APHIS originally deregulated RR sugar beets in 2005. A coalition of environmental groups and organic seed companies, led by the Center for Food Safety, challenged the USDA approval in 2008. It argued that GE sugar beets would contaminate organic and non-GE farmers of […]

(Beyond Pesticides, July 20, 2012) On Thursday, July 19, the U.S. Environmental Protection Agency (EPA) announced it had formally refused to recognize that honey bees face an “imminent hazard” and denied a request by beekeepers to immediately suspend the use of pesticides that pose harm to pollinators. The decision comes in response to a legal petition filed earlier this year by twenty-five beekeepers and environmental organizations, citing significant acute and chronic bee kills across the United States linked to neonicotinoid pesticides, particularly clothianidin. “We’re disappointed. EPA has signaled a willingness to favor pesticide corporations over bees and beekeepers,” said Steve Ellis, a petitioner and owner of Old Mill Honey Co, with operations in California and Minnesota. “This decision puts beekeepers, rural economies and our food system at risk. And the injury we are sustaining this year will be unnecessarily repeated.” This spring and summer, beekeepers from New York to Ohio and Minnesota, are reporting extraordinarily large bee die-offs, due, in part, to exposure to neonicotinoid pesticides. The die-offs are similar to what beekeepers have reported in the past few weeks in Canada (where EPA has admitted there are 120 bee kill reports, a huge number). On average, the U.S. Department […]

(Beyond Pesticides, July 13, 2012) Seventy-five family farmers, seed businesses, and agricultural organizations representing over 300,000 individuals and 4,500 farms filed a brief on July 5, 2012 with the United States Court of Appeals for the Federal Circuit in Washington asking the appellate court to reverse a lower court’s decision from February dismissing their protective legal action against agricultural giant Monsanto’s patents on genetically engineered seed. The plaintiffs brought the preemptive case against Monsanto in March 2011 in the Southern District of New York and specifically seek to defend themselves from nearly two dozen of Monsanto’s most aggressively asserted patents on GMO seed. They were forced to act preemptively to protect themselves from Monsanto’s abusive lawsuits, fearing that if GMO seed contaminates their property despite their efforts to prevent such contamination, Monsanto will sue them for patent infringement. Beyond Pesticides signed on as a plaintiff in the suit in June 2011. “Monsanto is known for bullying farmers by making baseless accusations of patent infringement,” said attorney Dan Ravicher of the not-for-profit legal services organization Public Patent Foundation (PUBPAT), which represents the plaintiffs in the suit against Monsanto known as Organic Seed Growers and Trade Association et al. v Monsanto. “They’ve […]

(Beyond Pesticides, July 6, 2012) The agribusiness conglomerate DuPont has received more than 30,000 damage claims arising from its sale of a pesticide that resulted in death and injury to hundreds of thousands of evergreen trees, particularly Norway spruce and white pine. DuPont marketed the pesticide, sold under the trade name Imprelis, based on a conditional registration that the U.S. Environmental Protection Agency (EPA) granted in 2010. Soon after Imprelis became commercially available the next spring, EPA began receiving widespread reports of tree death and injury from landscapers and residential users who had applied the pesticide according to its label conditions. EPA issued an immediate stop sale order for Imprelis on August 11, 2011 after DuPont submitted reports of more than 7,000 reports of tree damage. The New York Times reports that DuPont has set aside $225 million for claims that have already been submitted, and that the payout could ultimately reach $575 million. These figures do not include costs related to a class-action lawsuit filed by thousands of homeowners, landscapers and others, consolidated in federal court in Philadelphia. Some claimants are frustrated by the pace of the claims process and communications from the company. “We’re hearing nothing,” said Janet […]

(Beyond Pesticides, July 3, 2012) Several organizations, including Occupy Wall Street Maui and GMO-Free Maui, as well as over 100 concerned citizens, held a protest on Thursday, June 28 in front of the Monsanto Corporation headquarters in Kunia on the Island of Oahu, Hawaii. According to the organizers, the protesters met in Kunia and marched over a half mile to the Monsanto, compound for two hours of roadside sign-waving and chanting, demanding that Monsanto leave Hawaii and saying they need real food not exported GMO seeds and chemical contamination. The group also demands that genetically engineered (GE) food be labeled. The protesters wore masks to protect themselves from pesticide drift and GE spores, and received lots of support from many in passing cars that honked their horns and waved in support. According to organizers, a nearby resident even came to find out what was going on and soon donned a mask himself as he was unaware of the dangers so close to his house. The resident expressed concern about the large trucks and equipment operating at night at Monsanto’s fields. Monsanto operates about 8,000 acres in Hawaii for GE seed production. According to organizers, these operations use the most valuable […]

(Beyond Pesticides, July 2, 2012) The French Ministry of Agriculture has issued a ban on the neonicotinoid pesticide thiamethoxam due to concerns over the chemical’s impacts on pollinators, especially honey bees. The pesticide product containing thiamethoxam, Cruiser OSR, is manufactured by Swiss chemical giant Syngenta and has been used as a seed treatment on canola seed. The French Agriculture Minister, Stephane Le Foll, had announced in June that his agency was considering a ban on the pesticide and asked Syngenta to submit any new data the company had on the chemical. Apparently finding this data insufficient evidence that thiamethoxam was safe for pollinators, the agency withdrew the permit for Cruiser OSR last Friday. The ban is expected to take effect at the start of the next canola planting season in late summer. Thiamethoxam is a neonicotinoid insecticide used to coat seeds prior to planting. When the seed germinates, the plant that grows from it takes the chemical up through its vascular system and expresses it through pollen, nectar, and guttation droplets from which bees forage and drink. Thiamethoxam is very closely related to another neonicotinoid insecticide, clothianidin. When insects ingest thiamethoxam, their digestive system metabolizes it to clothianidin, killing the […]

(Beyond Pesticides, June 25, 2012) The Canadian governmental authority responsible for pesticide registration has expanded its re-evaluation of neonicotinoid pesticides to include two additional compounds linked to honey bee deaths and Colony Collapse Disorder (CCD). Health Canada’s Pest Management Regulatory Agency (PMRA) announced on June 12 that it has added clothianidin and thiamethoxam and their associated products to its ongoing re-evaluation of imidacloprid. The re-evaluation of these pesticides will focus on resolving issues related to environmental risk and specifically the potential effects of neonicotinoids on pollinators. The re-evaluation will consider all agricultural uses of neonicotinoid insecticides, including soil applications, seed treatment, as well as foliar and greenhouse uses. The Canadian announcement follows France’s decision earlier this month to initiate its own review for thiamethoxam that could result in the cancelation of allowances for using the pesticide. Neonicitinoids are highly toxic to a range of insects, including honey bees and other pollinators. They are taken up by a plant’s vascular system and expressed through pollen, nectar, and gutation droplets from which bees forage and drink. Neonicotinoids are particularly dangerous because, in addition to being acutely toxic in high doses, they also result in serious sublethal effects when insects are exposed to […]

(Beyond Pesticides, June 4, 2012) France’s Agriculture Minister Stephane Le Foll announced plans on Friday to cancel Swiss manufacturer Syngenta’s registration to treat canola seed with the neonicotinoid insecticide thiamethoxam, a chemical cousin of the bee-killing pesticide clothianidin, in a move to protect honey bees from Colony Collapse Disorder (CCD). When honey bees are exposed to thiamethoxam, it breaks down in their bodies to, clothianidin, which Beyond Pesticides is petitioning the Environmental Protection Agency (EPA) to ban due to a preponderance of adverse effects data and inadequate registration safety testing. Both pesticides have been shown in numerous scientific studies to play a key role in CCD. As France acts to protect its pollinators from pesticides, the U.S. continues to allow the uses of theses highly toxic chemicals to continue. Tell Congress and EPA that the U.S. should join France in taking a precautionary approach to our pollinator crisis. The chemical manufacturer Syngenta has two weeks to report its own evidence before the ban officially goes into effect. If enacted, France’s Agriculture Ministry stated that the ban will take effect before the start of canola sowing season in late summer. Minister Le Foll reinforced the fact that farmers do not need […]

(Beyond Pesticides, May 30, 2012) A settlement between plaintiffs and the manufacturer of the endocrine disrupting herbicide atrazine, Syngenta, will pay $105 million to settle a nearly 8-year-old lawsuit and could help reimburse community water systems (CWS) in 45 states that have had to filter the toxic chemical from its drinking water, according to news reports. It will provide financial recoveries for costs that have been borne for decades by more than 1,887 CWSs that provide drinking water more than one in six Americans across at least 45 states. “The scope of this historic settlement is enormous and its protection of the health of millions of Americans across the country is a huge benefit to the public, the environment, and the taxpayers,” the lead plaintiffs’ lawyer Stephen M. Tillery told the media. The individual amounts that eligible CWSs will recover will be calculated based on the levels of atrazine and frequency of atrazine contamination measured in the water of impacted CWSs and the population served by each CWS. The 300 CWSs with the highest contamination levels will recover 100 percent of their costs. Atrazine Settlement Details Ӣ Under the reported settlement, Syngenta will pay $105 million to pay the claims […]

(Beyond Pesticides, May 25, 2012) Biologists at the University of California at San Diego (UCSD) have discovered that a small dose of the commonly used neonicotinoid crop pesticide imidacloprid turns honey bees into “picky eaters” and affects their ability to recruit their nestmates to otherwise good sources of food. The results of the experiments, detailed in this week’s issue of the Journal of Experimental Biology (abstract), shed light on one of the main culprits suspected to be behind the recent declines in honey bee colonies and detail the particular ways that the substance impedes the functions of the colony. Since 2006, beekeepers in North America and Europe have lost about one-third of their managed bee colonies each year due to “colony collapse disorder.” While the exact cause is unknown, researchers believe pesticides have contributed to this decline. One group of crop pesticides, called “neonicotinoids,” has received particular attention from beekeepers and researchers. Neonicotinoids, including clothianidin and thiamethoxam, in addition to imidacloprid, are highly toxic to a range of insects, including honey bees and other pollinators. They are taken up by a plant’s vascular system and expressed through pollen, nectar and gutation droplets from which bees forage and drink. They are […]

(Beyond Pesticides, May 21, 2012) American farmers are growing increasingly more frustrated with the lack of commercially available seeds that have not been pretreated with pesticides. Farmers across the Midwest have called on federal officials this week to provide greater access to seeds without pesticide treatments. The request comes as scientists and beekeepers highlight the nearly pervasive use of neonicotinoids as seed treatments on corn as a critical factor in recent bee die-offs, including colony collapse disorder (CCD). Beekeepers from Minnesota to Ohio to Canada report large losses after their hives forage near treated cornfields. Scientists from Purdue University and a multi-year series of studies from Italy point to toxic dust, or neonicotinoid-contaminated powder from recently planted corn fields as key pesticide exposure pathways for bees. The request comes on the heels of a report aired by NBC Nightly News this week entitled “Bee Deaths Linked to Pesticides”, as well as recent reports of large bee kills in Ohio. “Farmers want to be good stewards and neighbors by purchasing seeds and growing corn that supports healthy honey bees and successful beekeepers,” said Doug Voss, a Minnesota corn farmer who also keeps beehives. We have a genuine concern with the majority […]

(Beyond Pesticides, May 15, 2012) Dow AgroSciences and Monsanto have filed paperwork for Canadian approval of corn and soybeans genetically engineered (GE) to withstand heavy applications of potent herbicides, reports the Ottawa Citizen. The chemical companies are seeking Health Canada and Canadian Food Inspection Agency assessments for the introduction of four varieties of GE corn and soybeans engineered to tolerate the highly toxic herbicides 2,4-D and dicamba. In the U.S., the federal Department of Agriculture (USDA) is in the process of reviewing Dow’s application for its 2,4-D-tolerant corn, as well. Beyond Pesticides and others recently submitted comments to USDA challenging this approval. Dow’s GE corn is modified to be tolerant to 2,4-D, which is contaminated with dioxin and linked to cancer, birth defects, and more. The company is introducing the new GE corn variety because weeds are becoming resistant to Roundup, the previous chemical of choice for herbicide-tolerant plants. However, solving herbicide resistance with a new, more toxic chemical is like using gasoline to put out a fire. It will cause even more damage to health and the environment, and in a few years, the pesticide industry will be marketing their next “solution” to the growing resistance problem. Dow states […]

(Beyond Pesticides, April 24, 2012) Dow Chemical has asked USDA for approval of genetically engineered (GE) corn, modified to be tolerant to the highly toxic 2,4-D herbicide, which is contaminated with dioxin and linked to cancer, birth defects and more. We know from experience that herbicide-tolerant crops are a bad idea. They increase toxic pesticide use, contaminate organic and non-GE farms, and contribute to herbicide-resistance. In fact, Dow introduced a new GE corn variety because weeds are becoming resistant to Roundup, the previous chemical of choice for herbicide-tolerant plants. However, solving herbicide resistance with a new, more toxic chemical is like using gasoline to put out a fire. It will cause even more damage to health and the environment, and in a few years, the pesticide industry will be marketing their next “solution” to the growing resistance problem. Read Beyond Pesticides full comments to USDA for Dow’s petition to approve 2-4,D-resistant GE corn. Tell USDA to stop this toxic experiment and deny Dow’s petition for 2,4-D tolerant corn. Sign your organization or business onto Beyond Pesticides’ comments or submit comments directly to the USDA docket. The deadline to sign on is Friday, April 27 at noon. Background: In a radio […]

(Beyond Pesticides, April 12, 2012) The U.S. Environmental Protection Agency (EPA) announced Monday that it has rejected a petition to ban the widely used herbicide 2,4-D, dismissing epidemiologic studies that link the pesticide to cancer, endocrine disruption, and other human health effects. In its announcement, EPA also responded to comments that Beyond Pesticides submitted in 2009, dismissing two studies that evaluate the relationship between the use of the chemical on lawns and the incidence of malignant lymphoma in pets. The petition was initially filed in 2008 by the Natural Resources Defense Council (NRDC). 2,4-D has been used in the U.S. since the 1940s, and as such is one of the oldest registered herbicides in the country. It made up roughly half of the herbicide known as Agent Orange, which was used to defoliate forests and croplands in the Vietnam War. According to EPA, 2,4-D is currently found in approximately 600 products registered for agricultural, residential, industrial, and aquatic uses. The use of 2,4-D is expected to increase significantly in the next few years with the recent announcement that Dow AgroSciences, the main manufacturer of the chemical, is seeking federal approval to sell corn seeds that have been genetically engineered to […]

(Beyond Pesticides, April 4, 2012) The world’s most popular weed killer can induce morphological changes in vertebrate animals, U.S. biologists studying its effect on amphibians say. University of Pittsburgh researchers have found that the weed killer Roundup, in sub-lethal and environmentally relevant concentrations, causes two species of amphibians to change their shape by interfering with the hormones of tadpoles and potentially many other animals. The study, “New effects of Roundup on amphibians: Predators reduce herbicide mortality; herbicides induce antipredator morphology” is the first to show that a pesticide can induce morphological changes in a vertebrate animal, biological sciences Professor Rick Relyea, PhD, said in a university release. The study was undertaken using simple created wetlands and introducing tadpoles from three species of amphibians —the leopard frog, American toad, and wood frogs. After three weeks, the tadpoles were examined. The impact of Roundup on the shape of tadpole tails was most noticeable in both the wood frog and leopard frog tadpoles. According to the study, “In wood frog and leopard frog tadpoles, Roundup induced relatively deeper tails in the same direction and of the same magnitude as the adaptive changes induced by dragonfly cues… [T]his is the first study to show […]

(Beyond Pesticides, April 3, 2012) Last week, the journal Science published two new studies linking neonicotinoid pesticide exposure to bee health. These two studies, one French, one British, add to a growing body of scientific literature and strengthen the case for removing pesticides toxic to bees from the market. The French study shows that pesticides interfere with honey bee brains, affecting their ability to navigate. The British research finds that pesticides prevent bumble bees from collecting enough food to produce new queens. These studies were released on the heels of an emergency legal petition by beekeepers and environmental groups, including Beyond Pesticides, that calls for the ban of the bee-killing pesticide clothianidin. Neonicitinoids are highly toxic to a range of insects, including honey bees and other pollinators. They are taken up by a plant’s vascular system and expressed through pollen, nectar and gutation droplets from which bees forage and drink. They are particularly dangerous because, in addition to being acutely toxic in high doses, they also result in serious sublethal effects when insects are exposed to chronic low doses, as they are through pollen and water droplets laced with the chemical as well as dust that is released into the […]
