(Beyond Pesticides, July 20, 2016) Farmers and land managers across the U.S. are being encouraged to plant pollinator habitat adjacent to farmlands to provide shelter and food for pollinator species. But according to a new study published last week, these conservation areas still put bees at risk for pesticide contamination, as they fail to provide spatial or temporal relief. This study emphasizes that meaningful solutions to reversing pollinator decline does not lie with focusing on planting pollinator habitat, but ensuring that these refuge areas are free from pesticide contamination, highly toxic to bees and other pollinators, and reducing the reliance on toxic chemical inputs in agriculture and other landscapes. The study, “Neonicotinoid-contaminated pollinator strips adjacent to cropland reduce honey bee nutritional status,” finds that pollinator habitat adjacent to agricultural areas not only becomes a source for pesticide, especially neonicotinoid, exposures, but also poses significant risk to honey bees. The authors, Christina Mogren, PhD, and former USDA entomologist, Jonathan Lundgren, PhD, initially sought to study whether increasing forage by planting pollinator habitat in an agricultural-dominated region would serve to buffer against the harmful effects of plant-incorporated pesticides. However, the authors note that it soon became apparent that the unintended consequence was […]

(Beyond Pesticides, July 12, 2016) Canadian environmental organizations sued the  Canadian Pest Management Regulatory Agency (PRMA) last week in a bid to overturn the approval of two neonicotinoid pesticides linked to the decline of honey bees and wild pollinators. The move comes amid growing awareness, action, and scientific evidence linking this widely used class of insecticides to the global decline of pollinator populations. The lawsuit, filed  by Ecojustice on behalf of  The David Suzuki Foundation, Friends of the Earth Canada, Ontario Nature, and the Wilderness Committee, argues that pesticide products containing two neonicotinoids, clothianidin and thiamethoxam, are unlawfully registered in Canada. The groups allege that PMRA failed to ensure that it had the data necessary to determine the environmental risks, particularly those concerning pollinators, posed by the chemicals. “The PMRA has taken a see-no-evil, hear-no-evil, speak-no-evil approach by repeatedly registering these neonicotinoid pesticides without important scientific information on their risks to pollinators,” said Charles Hatt, staff lawyer at Ecojustice. Under Canada’s Pest Control Products Act, PMRA must have “reasonable certainty” that a pesticide will not cause harm to the environment before it is registered. The groups also note that several thiamethoxam-based products have been registered by the agency for years […]

(Beyond Pesticides July 1, 2016) Lawmakers in France approved plans to totally ban neonicotinoid pesticides by 2018, based on their link  to declining populations of pollinators, specifically bees. This new restriction would go above and beyond current European Union (EU) restrictions on neonicotinoids, which limit the use of neonicotinoids, but do not ban them. The outright ban on neonicotinoid pesticides in France was adopted by a narrow majority of the  country’s  National Assembly, as part of a bill on biodiversity. While the bill must still gain the approval of the French Senate, which rejected it in a previous reading, passage by the Assembly is significant, as France becomes the first country to join state and local movements to eliminate the use of these toxic chemicals. Neonicotinoids have been found by  a growing body of scientific literature  to be linked to honey bee and other pollinator declines. In light of these findings, in 2013 the European Commission  voted to suspend  the use of neonicotinoid pesticides for two years. The ban came several months after the European Food Safety Authority (EFSA)  released a report  identifying “high acute risk” to honey bees from uses of certain neonicotinoid chemicals.   Along with recent reports […]

(Beyond Pesticides, June 30, 2016) In a move that goes one step further than the recently passed state-wide bill restricting consumer sales of neonicotinoid (neonics) products, Howard County, Maryland has taken the initiative to restrict the use of neonicotinoids on parklands. The new policy, announced June 16, cites the growing number of studies linking neonicotinoid use to adverse effects on pollinator species. The Department of Recreation and  Parks (DRP) manages approximately 10,000 acres of parkland within Howard County. According to the new policy and procedure, DRP is restricting the use of neonicotinoids, “due to recent research suggesting that there is a link between pesticides that contain neonicotinoids negatively effecting populations of pollinator species, such as; honeybees, native bees, butterflies, moths and other insects.” Neonics were often used on parklands for grubs on turf, Japanese beetles on trees,  and aphids on flowers and are now prohibited on all County parkland, including sports fields, garden plots, golf course and open space. Exemptions exist for agricultural uses and invasive pest infestations. Read the new neonicotinoid policy. Just this past May, Maryland officially became the first state in the nation to pass legislation  against neonicotinoids. The state legislature passed the  Maryland Pollinator Protection Act […]

(Beyond Pesticides, June 24, 2016) The U.S. Department of Agriculture (USDA), during its Pollinator Week Festival at the “People’s Garden” on Friday, has shut out environmental public interest groups that are advocating pesticide restrictions to protect bees. Instead, the agriculture agency is teaming up with other federal agencies and chemical industry groups that advocates say have been tone deaf to beekeepers’ pleas for federal government action. This new controversy emerges in the midst of an escalating pollinator crisis with 44% bee colony losses in the last year. Advocates, who bring the voice of independent science and point to the dangers of bee-toxic neonicotinoid insecticides as a major contributor to the decline in pollinator populations, have been disinvited to the event. Meanwhile, the Pollinator Partnership, an organization closely affiliated with the chemical industry (Bayer, Syngenta, BASF, CropLife, have all been previously listed as sponsors) will be in attendance. Groups like Beyond Pesticides, which bridges environmental, consumer and farm interests, have participated for several years in the Festival. “The foundation for a constructive dialogue between federal agencies and the public regarding the decline of our critical pollinator populations rests upon the free exchange of information and viewpoints,” said Jay Feldman, executive director […]

(Beyond Pesticides, June 23, 2016) A truck full of dead bees made its final stop yesterday at a rally outside the headquarters of the U.S. Environmental Protection Agency (EPA), culminating a coast-to-coast tour to raise awareness about recent massive declines in pollinators. While the millions of dead bees stayed on the truck, advocates and beekeepers, including Beyond Pesticides, delivered over 4 million signatures urging an immediate ban on bee-killing pesticides. “In the five years since I started keeping bees, I’ve seen many hives killed by pesticides,” said James Cook, a Minnesota-based beekeeper who has been driving the truck across the country since last Monday. “If some fundamental things don’t change, it’s going to be really hard for beekeepers to adapt to the environment around us.” Bees pollinate most of the world’s most common crops, including summer favorites like peaches and watermelon. But over 40 percent of U.S. honeybee hives die each year, costing the farming and beekeeping industry more than $2 billion annually. The most significant culprit in the bee die-off is the widely-used class of pesticides called neonicotinoids, or neonics. Last spring EPA began a process to assess four types of neonics and their impacts on pollinators. In January […]

(Beyond Pesticides June 20, 2016) As the end of the school year approaches, two first grade classrooms at local District of Columbia Public Schools (DCPS) got to learn about the importance of pollinators firsthand when DC-based nonprofit Beyond Pesticides visited their school. In a lead up to National Pollinator Week, Beyond Pesticides teamed up with owner and founder of The Bees Waggle, Jessica Goldstrohm, to provide a fun, hands-on lesson about pollination, and why it is important to our food system. Students were given a lesson on biodiversity, soil health, and the negative effects of pesticides on pollinators before building some pollinator-friendly habitat for their schools and homes. The day of learning kicked off at Brightwood Education Campus, located in Northwest DC, where students listened to a lesson developed by Ms. Goldstrohm, who donned a set of bee wings for the event. After receiving some background on the role of pollinators in our food system, the children participated in several hands on activities that reiterated the key points within the curriculum. Six volunteers stepped to the front of the class to demonstrate the interconnectedness of all living organisms by participating in a biodiversity web simulation. Here, the scholars learned that […]

(Beyond Pesticides, June 17, 2016) The pesticide industry has weakened and delayed pesticide reforms and is shaping new state pollinator “protection” plans nationwide that do little to protect bees, according to a new Friends of the Earth report.  The report is being released in advance of  Pollinator Week (June 20-26, 2016), as people assemble to ask for improved protection for pollinators. The investigation, Buzz Kill: How the Pesticide Industry is Clipping the Wings of Bee Protection Efforts Across the U.S., reveals an array of pesticide industry tactics to slow urgently needed pollinator protection measures at federal and state levels. The report details how new state pollinator protection plans, many still unfinished, have been heavily influenced by pesticide industry interests. According to the report, industry is spending hundreds of thousands of dollars on lobbying to delay state and federal action on the chemicals they manufacture. As a result, state pollinator protection plans across the U.S. are falling short in several ways, including: State pollinator protection plans currently provide more protections for pesticides and pesticide users than for bee keepers and bee colonies. Pesticide industry influence is pervasive throughout states’ legislative and regulatory planning efforts. Plans lack metrics to measure effectiveness, improvement […]

(Beyond Pesticides, June 14, 2016) To celebrate National Pollinator Week, June 20-26, 2016, several Washington, DC restaurants have teamed up with Beyond Pesticides and the Center for Food Safety to launch a campaign, “Made by Pollinators,” to protect pollinators suffering steep declines. With one out of every three bites of food reliant on bees, the participating restaurants’ patrons will be treated to a special menu featuring pollinator-friendly food and provided with information on what they can do to help pollinators. The restaurants hope to increase public awareness on the importance of pollinators and steps that can be taken to reverse the decline. Participating  restaurants include Busboys and Poets, Founding Farmers, Lavagna, the Tabard Inn and Restaurant Nora. Of the 100 crop varieties that provide 90% of the world’s food, 71 are pollinated by bees. Honey bees alone pollinate 95 kinds of fruits, nuts and vegetables, such as apples, avocados, almonds, and cranberries. The value of pollination services to U.S. agriculture alone amounts to nearly $30 billion and about 80% of flowering plants require animal pollination. A recent government survey reports that U.S. beekeepers lost 44 percent of their colonies between spring 2015 and 2016 —the second highest loss to date. […]

(Beyond Pesticides, June 6, 2016) Bayer CropScience’s appeal of the cancellation of their toxic pesticide flubendiamide by the U.S. Environmental Protection Agency (EPA) was rejected by EPA’s Chief Administrative Law Judge (ALJ) Susan Biro on Thursday, June 1. Judge Biro dismissed the complaints, saying that the agency was acting within its authority when it pulled its approval for the pesticide earlier this year after the two manufacturers, Bayer CropScience and Nichino America, failed to meet the terms laid out in a 2008 conditional registration. A startling number of pesticides, nearly 65% of the more than 16,000 pesticides now on the market, were first approved by the process of “conditional registration,” a loophole in which EPA allows new pesticides on the market without the full range of legally mandated toxicity tests for a full registration. Meanwhile, the Canadian Pest Management Regulatory Agency finalized its  decision to discontinue granting new conditional registrations, also on June 1. In 2008, EPA granted Bayer a “conditional” registration for flubendiamide, a classification that allows a new pesticide to be registered and used in the field, despite outstanding data points on its toxicological impact. In this case, original data submitted to EPA by Bayer showed concern over […]

(Beyond Pesticides, June 3, 2016) Despite recent reports of continuing bee losses across the U.S., the U.S. Environmental Protection Agency (EPA) has announced plans to reevaluate the use of the bee-toxic insecticide sulfoxaflor, and is proposing an amended registration. Sulfoxaflor’s initial 2013 registration was challenged by beekeepers and subsequently vacated by the Ninth Circuit Court of Appeals due to overwhelming risks to bees and EPA’s inadequate review of the data. Last September, the  Ninth Circuit Court of Appeals unequivocally rejected  EPA’s registration of sulfoxaflor. The Court concluded that EPA violated federal law when it approved sulfoxaflor without reliable studies regarding the impact that the insecticide may  have on honey bee colonies. The Court vacated EPA’s unconditional registration of the chemical, meaning that sulfoxaflor could no longer be used in the U.S. This decision was in response to a suit filed by beekeepers challenging EPA’s initial registration of sulfoxaflor, which cited the insecticide’s threat to bees and beekeeping. The case:  Pollinator Stewardship Council, American Honey Producers Association, National Honey Bee Advisory Board, American Beekeeping Federation, Thomas Smith, Bret Adee, Jeff Anderson v. U.S. EPA  (9th Circuit U.S. Court of Appeals,”¯No. 13-7234) According to the court decision, EPA skirted its own regulations […]

(Beyond Pesticides June 2, 2016) United States Department of Agriculture (USDA) Secretary Tom Vilsack recently released a Proclamation for National Pollinator Week, which is set to take place from June 20-26, 2016. National Pollinator Week began ten years ago when the U.S. Senate unanimously approved the designation of a week in June to address the urgent issue of declining pollinator populations. Pollinator week has since grown to be an international celebration of the valuable ecosystem services provided by bees, birds, butterflies, bats and all other pollinator species. While much remains to be done to combat contributing factors to pollinator declines, such as the use of neonicotinoid pesticides and disappearing pollinator habitat, National Pollinator Week is a chance to reflect and celebrate the achievements of the past year, while simultaneously raising awareness of the important role pollinators play in our daily lives. This year, to help increase education and bring awareness to the issue of pollinator declines, Beyond Pesticides and the Center for Food Safety are teaming up with several Washington, DC area restaurants to launch a “Made by Pollinators” campaign. Participating  restaurants, which include Founding Farmers, Lavagna, Tabard Inn and Restaurant Nora, will  educate the public on the importance of […]

(Beyond Pesticides, May 26, 2015) Maryland’s historic Pollinator Protection Act, (SB 198 and HB 211) may be in danger. Last month, lawmakers approved the bill by a 98-39 vote in the Maryland House of Delegates, however it faces the possibility of a veto by Governor Larry Hogan (R). While the governor’s office says that the bill is currently under review, according to local news source WBAL, the governor is prepared to veto the bill, which he has until tomorrow, Friday, May 27, to do. If the governor does veto the bill, Maryland’s Pollinator Protection Act will go back to the legislature for an override vote, which will take place in early 2017. Meanwhile, beekeepers continue to lose their bees at unprecedented rates. Last week, we reported results of 2015-16 Colony Loss Survey, which show no sign that the crisis of abating. According to the survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. WBAL reports that the governor is likely to veto the bill because of […]

(Beyond Pesticides, May 19, 2016) Using fear without facts, Congress is yet again attempting to gut Clean Water Act (CWA) provisions that protect waterways and communities from excessive pesticide pollution. In a move that was blasted by House Democrats this week, HR 897  (which was introduced as the Reducing Regulatory Burdens Act of 2015) was renamed the  Zika Vector Control Act, despite the fact that the bill does not actually do anything to address the threat of Zika. The legislation was defeated Tuesday on a suspension vote, 262-159, however the bill will be going to the Rules Committee on Monday, with anticipated House floor activity on Tuesday, May 24. (Take action: urge your representative to oppose HR 897.) “In a brazenly political act, the Republican leadership is trying to mask gutting the Clean Water Act as having something to do with fighting Zika,” Drew Hammill, spokesman for House Minority Leader Nancy Pelosi (D-CA), said in a statement to The Hill. “This bill has nothing to do with Zika and everything to do with Republicans’ relentless special interest attacks on the Clean Water Act,” he said. “It will do nothing to stem the growing threat of the Zika virus.” The bill […]

(Beyond Pesticides, May 17, 2016) It was 10 years ago that commercial beekeepers first reported widespread, unsustainable winter losses of their honey bee colonies. A decade after the alarm was first sounded on pollinator declines, results of 2015-16 Colony Loss Survey show no sign the crisis of abating. According to the Bee Informed Partnership survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. Beekeepers factor in that a small percentage, <15% of their colonies, will be lost each winter, but do not expect to lose colonies during the summer, when there is amble forage and nectar for bees. The costs beekeepers must incur to keep their hives alive continue to increase. More time and money is spent to maintain their hives, yet losses continue to be staggering ”” and unsustainable. As colony collapse disorder (CCD), the cryptic loss of honey bee colonies with no sign of dead bees in or around the hive, has faded from public discussion, concerns over pollinator declines in general, from bees […]

(Beyond Pesticides, May 3, 2016) In a bipartisan victory for bees, last week the Connecticut House of Representatives unanimously (147-0) passed a wide-ranging bill aimed at protecting declining pollinator populations within the state from toxic neonicotinoid (neonic) pesticides. Bill No. 231, An Act Concerning Pollinator Health, was also passed unanimously (36-0) through the Connecticut State Senate on April 21, and now goes to Governor Dannel P Malloy for his signature. Earlier in April, both houses of the Maryland legislature passed the Maryland Pollinator Protection Act, which is currently awaiting action by Governor Larry Hogan (R). Connecticut’s bill addresses a broad range of concerns relating to pollinator health, from pesticides to parasites and habitat remediation, within both residential and agricultural settings. In summary, the bill does the following: Prohibits applying neonicotinoid insecticide (a) to linden or basswood trees or (b) labeled for treating plants, to any plants when such plant bears   blossoms; Bee health experts identified the application of systemic neonicotinoids to Tilia trees as a significant concern for pollinator health after a spate of massive bee-kill incidents on the west coast. In June 2013, over 50,000 bumblebees were killed after a neonic was applied to a linden trees in […]

(Beyond Pesticides, April 28, 2016) This week, Antioch College in Yellow Springs, Ohio,  became the third university to become a neonicotinoid-free campus.  Antioch College gains recognition from the Beyond Pesticides’ and Center for Food Safety’s  BEE Protective  Campaign, which seeks to protect honey bees and other pollinators from harmful pesticides. Signing the  BEE Protective  resolution, Antioch signaled its continued commitment to using neonicotinoid-free insecticides on campus, making them one of the leading higher education institutions committed to the protection of pollinator species. In addition to joining the Bee Protective Campaign, the Village of Yellow Springs, where Antioch is located,  is  considering an organic land care policy, and Beyond Pesticides is working with the Village to assist with a transition to organic turf care. “At Antioch College, we have an opportunity, and an urgency, to be change leaders in turning around pollinator decline, exposing misleading research and recognizing the importance of inter-species cooperation. To paraphrase our president Thomas Manley, ”˜If we are not leaders in discovering and implementing  new and better ways of living  , then what is the point?’” said Beth Bridgeman, the faculty member who drove the effort to ban neonicotinoids from campus. Antioch students and staff maintain about […]

(Beyond Pesticides, April 19, 2016) Last week the Environmental Working Group (EWG) released its annual Shoppers Guide to Pesticides in Produce, highlighting the critical importance of eating organic food to avoid pesticide residues that endanger human health. Beyond Pesticides’ Eating with a Conscience database complements EWG’s report by identifying the many additional reasons it is essential to choose organic for a healthy future. Although information on residues in conventional produce listed in the “Dirty Dozen” is helpful in alerting consumers and encouraging organic, it only tells part of the story. It turns out that even those food commodities in EWG’s “Clean Fifteen” may be grown with hazardous pesticides that get into waterways and groundwater, contaminate nearby communities, poison farmworkers, and kill pollinators and wildlife, while not all showing up at detectable levels on our food. For its report, EWG analyzed over 35,000 samples of pesticide residue collected by the U.S. Department of Agriculture. After 5 years at the top of the list, apples dropped to number two, replaced by strawberries. The organization reasons that a recent EU ban on the chemical diphenylamine, a fungicide linked to reproductive effects, kidney/liver damage, as well as groundwater contamination and toxicity to aquatic organisms, […]

(Beyond Pesticides, April 18, 2016) Major pesticide manufacturer Scotts Miracle Gro announced on Tuesday that it will immediately being phasing out neonicotinoid insecticides, including imidacloprid, clothianidin, and dinotefuran from its outdoor-use Ortho brand by 2017. Neonicotinoids (neonics) have  consistently been implicated  as a major contributing factor in pollinator declines. They can cause  changes in bee reproduction, navigation, and foraging, and even the suppression of bee immune systems. In its press release, the Ortho brand announced that it was partnering with Pollinator Stewardship Council to help educate homeowners on the “safe and appropriate use of pesticides.” “While agencies in the United States are still evaluating the overall impact of neonics on pollinator populations, it’s time for Ortho to move on.” Tim Martin, general manager of the Ortho brand said. “As the category leader, it is our responsibility to provide consumers with effective solutions that they know are safe for their family and the environment when used as directed. We encourage other companies and brands in the consumer pest control category to follow our lead.” Neonics have emerged as the leading class of pesticides responsible for bee decline. While neonicotinoid insecticides have been responsible for high profile bee kills from high doses […]

(Beyond Pesticides, April 11, 2016) In a historic move, the Maryland legislature voted to become the first state in the nation to ban consumers from using products containing neonicotinoid pesticides, a class of bee-toxic chemicals that has been linked to the startling decline in bees and other pollinators around the world. The bill now heads to Governor Larry Hogan to sign or veto. The Pollinator Protection Act was approved by lawmakers on Thursday by  a 98-39 vote in the Maryland House of Delegates. While consumers will not be allowed to buy pesticide products containing neonicotinoids starting in 2018, the legislation’s  reach does not extend to farmers, veterinarians, and certified pesticide applicators, who will still be permitted to apply  the chemicals. Consumers can also buy treated plants and seedlings from stores without any labeling. Cumulatively, these present major sources of exposure for bees and other pollinators. The bill originally included a requirement that companies put labels on plants and seeds that are treated with neonicotinoids, but that provision was ultimately pulled from the bill. Hardware stores  like Home Depot and Lowe’s  had previously announced that they were voluntarily phasing out the supply of neonicotinoid-treated plants over the next two to three […]

(Beyond Pesticides April 6, 2016) Hot off the heels of the NCAA basketball tournament, a national title is not the only thing Villanova University has to celebrate this week. The campus, located near Philadelphia, PA, recently became the second school in the nation to receive recognition from the Beyond Pesticides’ and Center for Food Safety’s BEE Protective Campaign, which seeks to protect honey bees and other pollinators from harmful pesticides. Signing the BEE Protective pledge, Villanova signaled its continued commitment to using neonicotinoid-free insecticides on campus, making them one of the leading higher education institutions committed to the protection of pollinator species. “For Villanova, sustainability is not just about energy and recycling,” said Liesel Schwarz, Villanova’s Sustainability Manager. “We look to make all aspects of campus life sustainable, including how we treat our campus grounds. This recognition only further solidifies the wonderful work our grounds department has done to not only make the campus beautiful and inviting for people, but also for pollinators.” Villanova maintains more than fifty pollinator-friendly plants on campus, including aster, black-eyed Susans, milkweed and mint. Along with planting pollinator-friendly habitat, the elimination of neonicotinoid pesticides on campus is an exemplary move by Villanova to protect pollinators. […]

(Beyond Pesticides, March 30, 2016) European researchers found  over 50 different types of pesticides in honey bees while  investigating more than 70 honey bee poisoning incidents. Their study, which detected neonicotinoids, pyrethroids, fipronil, and others, highlights the large number of toxic pesticides to which bees are exposed in the environment from agricultural fields to  home gardens. The study results add to the body of knowledge connecting bee poisoning to pesticide exposure. The study, which is a multi-residue analysis to determine pesticides in honey bees   from poisoning incidents, was published in the Journal of Chromatography by a team of researchers from the National Veterinary Research Institute in Poland.   57 pesticides were found in 73 samples of poisoned honey bees, with four pesticides on average, and up to 13 determined simultaneously in a honey bee sample. The compounds detected include 21 insecticides and their metabolites, 20 fungicides, 12 herbicides, 2 acaricides and 2 veterinary medicinal products metabolites.  Among them, metabolites of imidacloprid, thiacloprid, fipronil, methiocarb and amitraz were found. Chlorpyrifos, clothianidin, dimethoate, and tebuconazole were most frequently detected. Of the herbicides detected only MCPA, 2,4-D and prosulfocarb were determined more than once. The authors believe that the study  results contribute […]
