(Beyond Pesticides, June 18, 2013) Neonicotinoid pesticides have broad ranging negative impacts not only on beneficial pollinators, but on overall biodiversity and ecosystem health, according to a new study published in the Journal of Applied Ecology. The study, conducted by David Goulson, Ph.D, of the University of Sussex, provides a detailed overview of the current literature on the economic and environmental risks of neonicotinoid pesticides. Dr. Goulson’s work draws stark and disturbing conclusions about the environmental fate of these systemic insecticides. First introduced in the early 1990’s as an alternative to the acutely toxic organophosphate and carbamate classes of  pesticides, neonicotinoids are now the most widely used insecticides in the world. They can be broadly applied as a spray or soil drench, however, the ability of these chemicals to translocate into a plant as it grows has led to the creation of a large market within conventional agriculture for seeds coated with these pesticides. As Dr. Goulson notes, global acceptance of treated seeds has undermined the adoption of alternative methods of conventional pest control, even  integrated pest management (IPM), which can reduce pesticide reliance  through monitoring and biological, structural, and cultural strategies. Instead, the treated seed market pushes farmers toward […]

(June 10, 2013, Beyond Pesticides) The Washington State Department of Agriculture (WSDA) on June 6 rejected a petition by Thurston County Commissioners to restrict sale, use and application of neonicotinoid insecticides. On April 8, 2013, the Commissioners requested the action by WSDA because of concerns about the effect of neonicotinoid insecticides on honey bee colony health. The Commissioners were acting on “substantial bee colony loss in 2012” reported by the Olympia Beekeepers Association. In its request, the Commissioners asked the state to implement a “restriction on the purchase, sale, distribution and application of the neonicotinoid class of insecticides for ornamental use to persons or entities with a valid WSDA pesticide applicator license” and indicated that “immediate action on a local level is appropriate and necessary.” Beyond Pesticides wrote a letter of support in favor of the petition. Neonicotinoids are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. They include imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam. According to the EPA, uncertainties have been identified since their initial registration regarding the potential environmental fate and effects of neonicotinoid pesticides, particularly as they […]

(Beyond Pesticides, May 13, 2013) According to preliminary results of a survey by the Bee Informed Partnership, 31.1 percent of managed honey bee colonies in the U.S. were lost during the 2012/2013 winter.  Though these preliminary loss reports are similar to the past six year average of 30.5 percent, the new loss numbers represent a 42 percent increase compared to the previous winter. Survey participants indicate that they consider a loss rate of 15 percent as “acceptable,” but 70 percent of participants suffered losses greater than this. With continued winter bee losses of over 30%, and concern whether there will be enough bees to pollinate U.S. crops this year, beekeepers and environmentalists say it is imperative  that regulators act by banning the neonicotiniod pesticides that have been implicated in the global decline of honey bee populations. In addition to this national report, several state level incidents of large scale honey bee colony losses have been reported. In a recent incident in Florida, citrus groves experienced an acute foliar poisoning that resulted in severely damaged colonies. Oranges had an early bloom this year, and were still blooming near the end of April. One beekeeper’s colonies suffered immense losses due to […]

(Beyond Pesticides, May 3, 2013) Despite the groundbreaking decision in Europe earlier this week to protect honey bees by suspending the neonicotinoid pesticides shown to be highly toxic, the  U.S. Department of Agriculture (USDA) and the U.S. Environmental Protection Agency (EPA) released a report yesterday which fails to address the overwhelming scientific evidence of neonicotinoid-related bee death and decline. The report presents no long-term, sustainable solutions to address the current bee crisis. Instead, the report recommends further research on the role of pesticides in honey bee health, further highlighting the stymied pace of U.S. regulatory efforts. The report follows on the National Stakeholders Conference on Honey Bee Health, which was led by federal researchers and managers and Pennsylvania State University in October 2012. Stakeholders at the conference included industry, federal officials, scientists, beekeepers, and activists who discussed several factors pertaining to adverse pollinator heath. Parasites, disease, genetics, poor nutrition, and pesticide exposure were highlighted at the meeting as synergistic factors in the observable nationwide honey bee decline. The report recommends further research on the impacts of pesticides on bees at the colony level in the field, but does not capture the science connecting pesticides to adverse effects or the need […]

(Beyond Pesticides, April 30, 2013) A landmark decision by the European Commission on Monday means that bee-killing, neonicotinoid pesticides will experience a continent-wide ban in Europe for two years. A  15 Member States majority  supported the ban, with eight against, and four abstaining. European Health and Consumer Commissioner Tony Borg explains, “Since our proposal is based on a number of risks to bee health identified by the European Food Safety Authority (EFSA), the Commission will go ahead with its text in the coming weeks. I pledge to do my utmost to ensure that our bees, which are so vital to our ecosystem and contribute over €22 billion annually to European agriculture, are protected.” The ban comes several months after the EFSA released a report identifying “high acute risk” to honey bees from uses of certain neonicotinoid chemicals. The moratorium will begin no later than December 1 this year. “We’re happy to see the EU take a leadership role to remove from the market these chemicals associated with colony collapse disorder and hazards to bee health. We’ll continue to push the U.S. Environmental Protection Agency (EPA) through legal and advocacy means to follow-up with urgent actions needed to protect bees,” says […]

(Beyond Pesticides, April 17, 2013)  Beekeepers in Bulgaria are revving up protests calling for a moratorium on the use of pesticides hazardous to bees, with a nationwide demonstration scheduled for Earth Day on April 22. The beekeepers are citing European and Bulgarian studies saying that neonicotinoid pesticides harm the immune systems of bees, shortening their lives and aggravating the mass disappearance of bee colonies. At an April 10 march, beekeeper Hristo Stoikov told Bulgarian National Television that in the past three years close to 60 percent of the bee population had disappeared. If the government failed to act, Bulgaria would be left with no bees. Separate reports said that about 200, 000 bees died in Bulgaria in 2012, about 20 per cent of the country’s bee population. The Union of Bulgarian Beekeepers is citing European and Bulgarian studies saying that neonicotinoid pesticides harm the immune systems of bees, shortening their lives and aggravating the mass disappearance of bee colonies. Beekeepers are upset that in the most recent European Union (EU)-level vote on banning the use of three neonicotinoid pesticides — clothianidin, thiamethoxam and imidacloprid, Bulgaria was among countries that abstained. At the beginning of 2013, the European Commission asked […]

(Beyond Pesticides, April 15, 2013) British supermarket chain, Waitrose Limited, has made the decision to phase out the use of bee-toxic neonicotinoid insecticides across its supply chain. This is happening in lieu of strong regulatory changes expected by the European Union (EU). The company, which has more than 200 branches across the UK, told its fruit, vegetable, and flower suppliers that they would have until the end of 2014 to stop using neonictoinoids, in particular imidacloprid, clothianidin, and thiamethoxam. These restrictions, delineated in Waitrose’s new Seven Point Plan for Pollinators, will eventually extend to some of their commodities, including oil seed and corn; however, the company did not announce any timeline for this phase-out. The managing director, Mark Price, released a statement that said, “Waitrose aims to be a restorative retailer, putting back more than we take from the environment, and we believe our decision on the three formulations of neonicotinoids is appropriate until conclusive evidence is put forward about the effects of these three chemicals.” The move follows in the footsteps of other high profile garden centers, hardware stores, and DYI retailers that have already stopped supplying these harmful chemicals on their shelves. Nevertheless, Waitrose’s commitment to the pollinator […]

(Beyond Pesticides, April 10, 2013) In response to the United Kingdom (UK) blocking attempts to introduce a Europe-wide ban on the world’s most widely used insecticides – neonicotinoids, some members of parliament (MPs) from the environmental audit committee (EAC) chided their government last week for relying on “fundamentally flawed” studies and failing to uphold its own precautionary principle, saying that the UK must suspend the use of the pesticides linked to serious harm in bees. The UK environment secretary, Owen Paterson, must end his department’s “extraordinary complacency” and suspend the use of pesticides linked to serious harm in bees, according to a damning report from an influential cross-party committee of MPs. The UK is blocking attempts to introduce a Europe-wide ban on the world’s most widely used insecticides, neonicotinoids, arguing that the scientific evidence is inconclusive. But MPs on parliament’s green watchdog, the environmental audit committee (EAC), said the government was relying on “fundamentally flawed” studies and failing to uphold its own precautionary principle. The EAC report criticizes ministers and the Department for Food, Environment and Rural Affairs (Defra) for their “extraordinarily complacent approach to protecting bees”. The report calls on the government to impose a ban on imidacloprid, clothianidin […]

(Beyond Pesticides, April 3, 2013)  Last week, Syngenta and Bayer CropScience proposed an action plan to forestall pending European Union (EU) restrictions on their neonicotinoid products that have been linked to global bee declines.  Stating that a ban on their products would not save hives, the plan focuses on implementing agricultural best management practices, planting habitat, and new research and development, all of which fail to seriously address the real problem that their products are highly toxic to bees. This new industry plan comes on the heels of the European Union (EU) stalemate on bee health, and after the EU food safety agency concluded that certain neonicotinoids pose unacceptable risks to bees. Public and regulatory scrutiny is now focused on the class of chemicals — neonicotinoids— linked to bee health decline. Neonicotinoids have been shown by numerous studies to adversely impact the health of  bees, as well as  birds and aquatic organisms. Beyond Pesticides, Center for Food Safety, and Pesticide Action Network North America joined beekeepers and other environmental and public health advocacy groups to sue the U.S. Environmental Protection Agency (EPA), calling for the suspension of the neonicotinoids, clothianidin and thiamethoxam. The science continues to document these […]

(Beyond Pesticides, March 21, 2013) Beyond Pesticides joins beekeepers, environmental and consumer groups in filing a lawsuit in Federal District Court against the U.S. Environmental Protection Agency (EPA) for its failure to protect pollinators from dangerous pesticides. The coalition seeks suspension of the registrations of insecticides- clothianidin and thiamethoxam- which have repeatedly been identified as highly toxic to honey bees, clear causes of major bee kills and significant contributors to the devastating ongoing mortality of bees known as colony collapse disorder (CCD).  The suit challenges EPA’s oversight of these bee-killing pesticides, as well as the agency’s practice of “conditional registration” and labeling deficiencies. Beyond Pesticides joins The Center for Food Safety, Pesticide Action Network North America, the Sierra Club, the Center for Environmental Health, and four beekeepers: Steve Ellis of Old Mill Honey Co. (MN, CA), Jim Doan of Doan Family Farms (NY), Tom Theobald of Niwot Honey Farm (CO) and Bill Rhodes of Bill Rhodes Honey (FL). See Press Release.

(Beyond Pesticides, March 18, 2013) The bee-killing neonicotinoid insecticides used for agriculture will continue to be used across the European Union (EU), as members failed to reach an agreement on the proposal to suspend their use on flowering crops over the next two years. The proposal had followed reports released by the European Food Safety Authority (EFSA), which found the continued use of neonicotinoids to be an unacceptable “high acute risk” to pollinators, particularly honey bees. However, three EU members opposed the plan to suspend, blocking the European Commission from attaining a qualified majority to adopt the proposed suspension. “The commission put the text to the vote and no qualified majority was reached, either in favor or against the text,” the European Commission said in a statement. Those opposing the proposal, notably UK and German Ministers, argued that more scientific evidence was needed as a suspension could cause disproportionate damage to food production, counter to research indicating bee declines also damage crop productivity. Pesticide companies Bayer and Syngenta have pressed hard following the EFSA report to effect this outcome. The decision, or lack thereof, runs contrary to a precautionary approach to ensuring healthy bees as critical for our food production […]

(Beyond Pesticides, February 12, 2013)  Is 2013 the year colony collapse disorder (CCD) begins impacting our food supply? According to the American Bee Journal, almond growers in California may not have access to the honey bee colonies necessary to pollinate this year’s crop. “We need 1.6 million colonies, or two colonies per acre, and California has only about 500,000 colonies that can be used for that purpose. We need to bring in a million more colonies but due to the winter losses, we may not have enough bees,” says Eric Mussen, PhD,  extension apiculturist at the University of California Davis (UC Davis) Department of Entomology. The problem, Dr. Mussen explains, is due to heavy losses this winter and less populous hives overall. Some beekeepers are reporting astonishing winter losses upwards of 90 percent, and in select cases complete colony loss. Honey production in 2012 was one of the worst years in the history of the United States, Dr. Mussen notes. Less honey means less food for overwintering bees, putting increased stress on colonies attempting to fight off the spread of CCD. CCD is the name given to the precipitous decline of honey bee populations around the world beginning in […]

(Beyond Pesticides, February 1, 2013) The European Commission announced yesterday its position against the use of neonicotinoid insecticides, pushing nations within the European Union (EU) to impose a two year suspension on their use. The proposal, put forward at a meeting of the Standing Committee on the Food Chain and Animal Health, would restrict the application of neonicotinoids as granules, seed-treatment or spray, on crops that are attractive to bees, particularly, sunflowers, rapeseed, corn, cotton, and cereal crops. Environmental groups say that this decision should signal the way forward for the U.S. Environmental Protection Agency (EPA) to suspend neonicotinoids in the U.S. “It’s a great thing,” said New York beekeeper Jim Doan, “I’m hoping that the EPA follows in their footsteps. While I recognize our government works differently, it says something that the European government has recognized the overwhelming data on the impact of these pesticides.” The announcement comes on the heels of research conducted by the European Food Safety Authority (EFSA) which indicated that three neonicotinoid insecticides””imidacloprid, clothianidin, and thiamethoxam, produced by Switzerland’s Syngenta and Germany’s Bayer, pose an unacceptable hazards to honey bees. In its report released January 16th, EFSA concludes that systemic contamination of neonicotinoid-treated crops, neonicotinoid […]

(Beyond Pesticides, January 17, 2013) The European Food Safety Authority (EFSA) yesterday presented its report which finds that the neonicotinoid class of insecticides poses unacceptable hazards to bees. The report concludes that certain crops treated with neonicotinoid chemicals –imidacloprid, clothianidin and thiamethoxam– are of “critical concern” for bee health. Beekeepers and environmental activists welcome these recent scientific findings that they say support a U.S. ban on these chemicals. According to Jay Feldman, Executive Director, Beyond Pesticides, “The EFSA report confirms what we have been asking EPA to recognize. Clothianidin and other neonicotinoids are highly toxic to bees, and should be banned by EPA and removed from the environment.” In its investigation, EFSA, which was tasked with assessing the risks associated with these chemicals to bee colony survival and development, found that systemic contamination of neonicotinoid-treated crops and contamination via dust place honey bees and the hives they return to at high risk. Exposure to contaminated dust pose a high risk to honey bees for all three neonicotinoids used on corn and certain other crops, as well as exposure to residues in nectar and pollen. High risks were also identified from exposure to guttation fluid from corn for thiamethoxam. EFSA considered […]

(Beyond Pesticides, December 19, 2012) The Congressional Research Service (CRS) issued its overview report, Bee Health: The Role of Pesticides, in response to a congressional request for more information on the connection between declines in bee populations, colony collapse disorder (CCD) and pesticides, particularly neonicotinoids. The 23-page report, dated December 11, 2012, summarizes the range of scientific studies and regulatory activities without offering a critique of what bee health advocates have identified as serious deficiencies in the regulatory review process and compliance with the pesticide registration law. The review gives equal standing to independent and industry science. The CRS report identifies a range of issues regarding: 1. Changes to managed and wild bee populations (indicating limited information); 2. Factors that are documented to impact bee health, including pesticides, pests and diseases, diet and nutrition, genetics, habitat loss, and beekeeper issues, highlighting that there are multiple exposure pathways that may work synergistically; 3. Scientific research on the role of pesticides; and, 4. Current research and regulatory activity regarding neonicotinoids, a neurotoxic insecticide impacting bees. The report reviews the ‘state of play’ on the issue of bee declines and finds that there are reported to be many factors that contribute to the […]

(Beyond Pesticides, December 14, 2012) Decision making advice by the Advisory Committee on Pesticides (ACP) and insecticide regulator, the Department for Environment, Food, and Rural Affairs (Defra), were harshly criticized on Wednesday by Members of Parliament (UK), as they discussed the problems associated with neonicotinoids, a group of neurotoxic insecticides linked to serious declines in bee and pollinator populations. The meeting was attended by Members of Parliament, members of the Advisory Committee on Pesticides, Lord de Mauley, the Parliamentary Under-Secretary of State, the Department for Environment, the Food and Rural Affairs and officials, bringing neonicotinoids and their impact on bees to the attention of the international community as well as at home. The discussion focused on the evidence used to make a decision on the allowance of neonicotinoids and plans for the future. ACP members indicated that evidence for future draft plans would be based on new studies developed in 2012 on the effects of neonicotinoids at the colony level, as well as the impact of neonicotinoids exposure in field tests, rather than in the lab. Research will likely fill the extant data gaps, the most important of which were identified by officials of Defra, the environmental regulatory agency in […]

(Beyond Pesticides, September 18, 2012) Take Action! On September 25, EPA will close its public comment period for the petition requesting the agency to suspend the bee-killing pesticide clothianidin. The U.S Environmental Protection Agency (EPA) has failed to recognize that pollinators face unique hazards from clothianidin, a neonicotinoid pesticide which is linked to disruptions in bee mobility, navigation, and feeding behavior. So far thousands of concerned beekeepers, gardeners, hobbyists and folks like you have told EPA to suspend clothianidin and protect pollinators now! Without your support, clothianidin’s effects on honey bees will continue to put beekeepers, rural economies, and our food system at risk. With one in three bites of food reliant on honey bee pollination, it’s imperative that we act now! Tell EPA to suspend the use of the bee-killer clothianidin and protect pollinators. See sample comments here. If you are having trouble submitting to the docket, click here. Background Colony Collapse Disorder (CCD) is the name given to the mysterious decline of honey bee populations around the world beginning in 2006. On average, the U.S. Department of Agriculture (USDA) reports that beekeepers have been losing over 30% of their honey bee colonies each year—but some are losing many […]

(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, 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 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, February 28, 2012) A study by researchers at the University of Padova in Italy and published in the journal Environmental Science and Technology has confirmed the findings of previous research showing that honey bees are exposed to toxic neonicotinoid insecticides during spring seed planting. Neonicotinoids are known to be highly toxic to honey bees and, yet, are used on millions of acres through North America every year. These findings lend even greater urgency to the need to take these chemicals off the market and ensure the continued survival of honey bees and the essential pollination services that they provide for our food system. Neonicotinoids, including clothianidin, imidacloprid, and thiamethoxam, are most commonly applied by coating crop seeds with the chemical. When these treated seeds are planted, the chemical becomes part of the plants vascular system and stays in the plant for the duration of its lifetime, expressing itself in the pollen. Previously, it had been thought that bees were only exposed to these chemicals through pollen and water droplets from treated plants, which would occur later in the season once the plants had grown and bloomed. However, the Italian study shows that bees are actually exposed to high […]
