(Beyond Pesticides, June 17, 2016) The pesticide industry has weakened and delayed pesticide reforms and is shaping new state pollinator âprotectionâ 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 statesâ 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, âMade by Pollinators,â to protect pollinators suffering steep declines. With one out of every three bites of food reliant on bees, the participating restaurantsâ 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 worldâs 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 âthe second highest loss to date. […]

(Beyond Pesticides, June 10, 2016) A proposal for a temporary ‘technical extension’ of the EU approval of the herbicide glyphosate failed to secure the support of a majority of EU governments at a meeting of the EU standing committee on plants, animals, food and feed on Monday. This action may force the withdrawal of the herbicide, widely sold as Monsantoâs Roundup, from shelves if no decision is reached by the end of the month, when its license expires. After a proposal to renew the license for glyphosate for up to 15 years failed to win support in two meetings earlier this year, the EU executive offered a limited 12 to 18 month extension to allow time for further scientific study. Yet, despite this compromise, the proposal failed to win the support of member states representing at least 65% of the EUâs population, which is needed for adoption, an EU official told The Guardian. Seven member states abstained from Mondayâs vote, 20 backed the proposal and one voted against, a German environment ministry spokeswoman said. According to the news source, Germany was among those that abstained from Mondayâs vote. Of note is that Bayer, the German chemical company, recently offered to […]

(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. Sulfoxaflorâs initial 2013 registration was challenged by beekeepers and subsequently vacated by the Ninth Circuit Court of Appeals due to overwhelming risks to bees and EPAâs inadequate review of the data. Last September, the  Ninth Circuit Court of Appeals unequivocally rejected  EPAâs 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 EPAâs 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 EPAâs initial registration of sulfoxaflor, which cited the insecticideâs 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,âÂŻNo. 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 âMade by Pollinatorsâ campaign. Participating  restaurants, which include Founding Farmers, Lavagna, Tabard Inn and Restaurant Nora, will  educate the public on the importance of […]

(Beyond Pesticides, June 1, 2016) A study  by researchers at Purdue University has concluded  that honey bees collect most of their pollen from non-crop plants that are frequently contaminated with agricultural and urban pesticides. The researchers found this to be true even in places where croplands dominate the area.  The study, which detected neonicotinoids, pyrethroids, fungicides, and others, highlights the large number of toxic pesticides to which bees are exposed to in the environment. Researchers collected pollen from Indiana honey bee hives at three sites over 16 weeks. The hives were placed in a variety of settings, such as an open meadow with wildflowers, woody shrubs and trees present (non-agricultural), the border of a corn field that was treated with the neonicotinoid clothianidin and three fungicides, and the border of a non-treated corn field. The pollen samples that were collected by the bees represented up to 30 plant families and contained residues from pesticides spanning nine chemical classes. The researchers found 29 pesticides in pollen from the meadow site, 29 pesticides in pollen from the treated cornfield, and 31 pesticides in pollen from the untreated cornfield. The most common chemical products found in pollen from each site were fungicides and […]

(Beyond Pesticides, May 26, 2015) Marylandâs 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 governorâs 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, Marylandâs 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 25, 2016) New York Cityâs Prospect Park is bringing in a herd of goats to fight back opportunistic species that are encroaching in an area of the park after damage caused by Hurricane Sandy. Rather than spray toxic weed killers like 2,4-D, triclopyr, or glyphosate, the Prospect Park Alliance used the grant money it obtained from the National Park Service to bring in these 4-legged weed warriors as a safe and environmentally friendly way to restore storm-damaged areas. “We are pleased to welcome these goats to Prospect Park to help us further the important woodland restoration work that has always been a focus for the Alliance,” Prospect Park Alliance President Sue Donoghue said to ABC7. “These goats will provide an environmentally-friendly approach to our larger efforts, which will not only beautify the Park, but make it more resilient to future storms.” After Hurricane Sandy barreled up the east coast, a roughly 1.5 acre area of Prospect Park was seriously damaged, with 100s of trees toppled. The disturbance has allowed so-called invasive species to move into the park, supplanting the regrowth of native species in the last remaining forested area in the borough of Brooklyn. Goats act as […]

(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 ââ 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 13, 2016)  Raising questions about Roundup’s (glyphosate) effects on soil health, a study published last month shows that the chemical  is toxic to soil fungus at doses well below levels which are recommended for agricultural use. The commercial formulation of Roundup is  more toxic than technical active ingredient,  glyphosate, highlighting the need to evaluate  full formulation  effects, including  so-called inert ingredients. The study, published in Environmental Science and Pollution Research, looked at Roundupâs effects on  a soil fungus, Aspergillus nidulans. Researchers found that a dilution of Roundup at a rate 100 times less than that  allowed in agricultural production corresponded with 50% mortality of the fungus. A dose only 50 times lower than the recommended application rate for agricultural uses resulted in 100% mortality of the fungus. Even at the median lethal dose (LD50) and lower concentrations, researchers saw impaired growth, cellular polarity, endocytosis and mitochondria (impaired average number, volume and metabolism). The study also found that Roundup has an effect on the soil fungusâ ability to break down nutrients for energy use. Rather than depleting mitochondrial activity, as found in animal cell studies, researchers found a stimulation of mitochondrial activity in the fungal cells, indicating a […]

(Beyond Pesticides, May 11, 2016) Another campus, Macalester College in St. Paul, Minnesota has pledged to become a designated BEE Protective campus. This recognition comes from Beyond Pesticidesâ and Center for Food Safetyâs BEE Protective Campaign, which aims to protect bees and other pollinators from harmful pesticides like neonicotinoids. As part of its  commitment, Macalester College will  no longer use neonicotinoids on its  campus grounds. Neonicotinoids are a class of pesticides known to have severe impacts on bee populations. Macalester is now one of several campuses around the country that have pledged to protect pollinators and move away from using harmful pesticides that are toxic to these beneficial creatures. Just last month,  Antioch College in Yellow Springs, Ohio pledged to become a BEE Protective campus. In addition to these campuses, several local communities and states are also taking a stand for pollinators by passing policies that restrict the use of bee-toxic pesticides. For more on how your campus or student group can support pollinators and become BEE Protective, visit the BEE Protective Ambassadors webpage. âMacalesterâs new resolution to help protect pollinators fits well with our Sustainability Plan and Sustainable Landscaping Master Plan. Iâm glad that our college has this opportunity […]

(Beyond Pesticides, May 10, 2016) Following an apparent accidental release of documents relating to the safety of the herbicide glyphosate, late last month the U.S. Environmental Protection Agency (EPA) also released and then retracted a preliminary ecological risk assessment of another toxic herbicide, atrazine. Under federal law, every pesticide registered in the United States is required to undergo a 15-year registration review to analyze human health and environmental impacts and determine whether the chemicalâs use should continue another 15 years. The last decade and a half have seen plethora of studies underscoring that atrazine is harmful to human health, and poses unreasonable adverse risks to ecological health, despite attempts by its major manufacturer, Syngenta, to silence and discredit its critics. EPAâs preliminary ecological risk assessment finds that for current uses at prescribed label rates, atrazine may pose a chronic risk to fish, amphibians, and aquatic vertebrate animals. Where use is heavy, the agency indicates that chronic exposure through built-up concentrations in waterways is likely to adversely impact aquatic plant communities. Â Levels of concern, a wonky equation that EPA produces to measure risk, were exceeded for birds by 22x, fish by 62x, and mammals by 198x. Even reduced label rates were […]

(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). Connecticutâs 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, May 2, 2016) A study published online last week has examined the effects of three neonicotinoids (neonics) on bumblebee colonies, from live bee kills to changed sex ratios. Neonics have been widely cited as contributing to  the demise of both managed and wild bee and pollinator populations. They can cause  changes in bee reproduction, navigation, foraging, and even the suppression of bee immune systems. The study, published in Scientific Reports, looked at field-relevant levels (2.5 parts per billion) of imidacloprid, thiamethoxam, and clothianidin, and found compound-specific effects at all levels, including within individual bee cells, individual bees, and whole colonies in semi-field conditions. Given the limitations of laboratory studies and field studies, researchers conducted a semi-field study to try to recreate and represent real world exposure patterns. The neonics were provided to the bees as an optional supply of sugar syrup, but were free to forage and did need to gather pollen in order to grow and raise offspring. Researchers found that imidacloprid and clothianidin displayed abilities to affect neuronal Kenyon cells, which help with learning, memory and multisensory integration. At the whole colony level, thiamethoxam altered the sex ratio, leaving more males than females. Both imidacloprid and […]

(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 Pesticidesâ and Center for Food Safetyâs  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. âAt 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, âËIf we are not leaders in discovering and implementing  new and better ways of living  , then what is the point?ââ said Beth Bridgeman, the faculty member who drove the effort to ban neonicotinoids from campus.

(Beyond Pesticides, April 25, 2016) Last week, the City Council of Milwaukie, Oregon passed a resolution that halts the use of bee-toxic neonicotinoid insecticides on city government and public property,  joining the growing number of local governments protecting pollinators.  Neonicotinoids  (neonics) have been widely cited in the demise of both managed and wild bee and pollinator populations.  The resolution specifically  restricts city government agencies from purchasing plants and seeds that have been treated with neonicotinoids and other systemic insecticides and urges public and private landscapers and homeowners to plant bee-friendly habitats.  Clackamas County will join with the Mayor’s office and City Council of Milwaukie to adopt an Integrated Pest Management Plan that mirrors the resolution. In addition to these stipulations, the City of Milwaukie is using this resolution to: urge all businesses, homeowners, and homeowner’s associations operating within the City ensure no plants, seeds, or products containing neonicotinoids are purchased, sold, or used within the City; and to clearly and accurately label any plants or materials that have been treated with a neonicotinoid or neonicotinoid-like insecticide; require that commercial pest service providers performing services on behalf of the City provide landscape services that encourage pollinator populations and support pollinator services; […]

(Beyond Pesticides, April 22, 2016) Today is Earth Day! As honey bees and other pollinators continue to suffer from staggering global declines, Beyond Pesticides works year-round through the BEE Protective campaign, launched Earth Day 2013, to support nationwide local action aimed at protecting pollinators from pesticides. Pollinators are a vital part of the environment, a barometer for healthy ecosystems, and critical to the nationâs food production system. With one in three bites of food reliant on bees and other species for pollination, the decline of honey bees and other pollinators demands swift action. The BEE Protective campaign includes a variety of educational materials to help encourage municipalities, campuses, and individual homeowners to adopt policies and practices that protect bees and other pollinators from harmful pesticide applications and create pesticide-free refuges for these critical  organisms. In addition to scientific and regulatory information, BEE Protective also assists people and communities with  a model community pollinator resolution and a pollinator protection pledge. Insecticides, specifically neonicotinoids, have increasingly been linked to bee declines. These chemicals are used extensively in U.S. agriculture, especially as seed treatment for corn and soybeans. Agriculture is not the only concern however, as pesticide applications in home gardens, city parks, […]

(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 Loweâs  had previously announced that they were voluntarily phasing out the supply of neonicotinoid-treated plants over the next two to three […]

The campus, located near Philadelphia, PA, recently became the second school in the nation to receive recognition from the Beyond Pesticidesâ and Center for Food Safetyâs 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. âFor Villanova, sustainability is not just about energy and recycling,â said Liesel Schwarz, Villanovaâs Sustainability Manager. âWe 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.â 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, April 5, 2016) Populations of wild, ground-nesting bees grow smaller in areas where agricultural production is high, according to Cornell University researchers. Both wild and managed pollinators are experiencing global population declines that have been linked to a range of factors stemming from human activity, to habitat loss, the spread of parasitic mites and diseases, climate change, and significantly, the use of toxic, systemic pesticides. This study underscores the wide ranging threat that conventional agricultural practices pose to wild insect pollinators. Cornell researchers explore the relationship between intensive agricultural production and the size of ground-nesting Andrena nasonii bees. These charismatic pollinators dig tunnels in the ground up to three  feet deep in which they store honey and nectar, and ultimately lay a single egg. They forage on a variety of fruit crops, and are well known and important pollinators of strawberries. Thus, scientists brought their study to areas in New York with large strawberry plantations. Researchers discovered a significant, positive correlation between the decreased size of female A. nasonii bees and their proximity to intensively farmed strawberry plots. âOnce we knew there was an effect of agriculture on the size of the bees, we took a random sample […]

(Beyond Pesticides, March 28, 2016) In the first test of a landmark beekeeper compensation law that works to protect beekeepers from the effects of toxic pesticides on their hives, Minnesota has recently compensated two beekeepers for pesticide drift that killed their bees. Investigators from the Minnesota Department of Agriculture (MDA) have confirmed what beekeepers and environmentalists have been saying: Even when pesticides are used in accordance with the label and the law, they can be acutely toxic to bees in everyday circumstances. Pam Arnold, an organic farmer who manages hives on her property, and Kristy Allen, another beekeeper who shares the same bee yard, were the first two beekeepers to actually receive compensation through the beekeeper compensation law. Last spring, a farmer across their road planted neonicotinoid (neonic) coated corn seeds on a windy day, resulting in the death of their bees as toxic dust from planting drifted on to their property. Tests performed by MDA during the investigation found acute levels of clothianidin in the dead bees, even days after the incident. Nearby dandelion weeds also showed significantly higher concentrations of the toxin. According to the MDA website, the case closing letter was sent in November 2015, but they […]

(Beyond Pesticides, March 16, 2016) Another study, this time from researchers at the University of Guelph, finds that at very low levels the neonicotinoid pesticide thiamethoxam affects  the foraging behavior of bumble bees, changing their floral preferences, hindering their ability to learn and extract nectar and pollen. This study is one of many that detail the negative effects of pesticides on beesâ learning behavior and ability to pollinate essential crops. Pesticides, like the neonicotinoid class of insecticides, have been implicated in the global decline of pollinator populations, while advocates call for  limiting pesticide exposures to reverse population declines. According to the authors of this Canadian study, âChronic exposure to a neonicotinoid pesticide alters the interaction between bumblebees and wild plants, âpublished in  the journal Functional Ecology, it is the first to explore how pesticides may impact the ability of bumble bees to  forage from common wildflowers that have complex shapes such as white clover and birdâs foot trefoil. The researchers found that bumble bees exposed to environmental levels of thiamethoxam (10ppb) took longer to collect pollen than unexposed bees, as well as foraged from different flowers. Importantly, this study reports that bumble bees that were not exposed to thiamethoxam are […]

(Beyond Pesticides, March 15, 2016) Executive agencies are falling short in their efforts to protect honey bees and other wild pollinators from catastrophic declines, according to a new report from the U.S. Government Accountability Office (GAO). GAO, an investigative agency that works on behalf of the U.S. Congress, was tasked by the Senate to evaluate the progress the Environmental Protection Agency (EPA) and U.S. Department of Agriculture (USDA) have made in their actions to address the multiple threats contributing to declining managed and wild pollinators. Since 2006, U.S. beekeepers have experienced unsustainable colony die-offs, averaging over 30% each year. Concurrent declines in wild and native pollinators are also occurring, though data on the magnitude of these losses have not undergone comprehensive scientific evaluation. While a range of factors, from habitat loss, to climate change, diseases, viruses, and parasites are all contributing to these declines, independent science has identified that pesticides, specifically a new class of systemic insecticides called neonicotinoids, are the major drivers of the crisis for both managed and wild bees. In fact, some studies show that the widespread exposure to neonicotinoids increases bees’ vulnerability to diseases, viruses, and mites. The GAO report recommends a number of action items […]
