(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. “Once 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 23, 2016) Last week, the Vermont House of Representatives passed a bill that authorizes state  regulation of pesticide-treated products,  including  telephone poles and coated seeds, that are exempt from federal pesticide regulations. H.861 is the latest in a string of laws introduced this legislative session in Vermont to address the impact of harmful neonicotinoid insecticides  on Vermont’s ecology and agriculture, and symbolizes a concentrated effort by the legislature to reverse pollinator declines within the state. If passed by the Senate and signed by the governor, the bill will  allow the Secretary of Agriculture to regulate above and beyond current federal laws, which exempt treated articles from regulation completely, and write appropriate rules in response to recommendations from a state Pollinator Protection Committee. The bill, which passed with wide support in the House, gives the Vermont Agency of Agriculture, Food and Markets the authority to regulate “treated articles,” a term coined by the Environmental Protection Agency (EPA) to denote products treated with pesticides, such as utility poles, commercial crop seeds, and lumber. Traditionally, EPA gives rulemaking authority over pesticides to states, but that authority does not extend to products pre-treated with pesticides, which, until this point, has posed […]

(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 bees’ 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, “Chronic exposure to a neonicotinoid pesticide alters the interaction between bumblebees and wild plants, “published 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 bird’s 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 […]

(Beyond Pesticides, March 10, 2016) Jonathan Lundgren, Ph.D., a top U.S. Department of Agriculture (USDA) entomologist who received a prestigious national award for civic courage  for his work on neonicotinoids and pollinator decline in the face of agency attempts to suppress his work, will be speaking at Cultivating Community and Environmental Health, the 34th National Pesticide Forum, April 15-16, 2016 in Portland, ME. Dr. Lundgren will join other top scientists and leaders who have stood up to protect human and environmental health, despite facing industry backlash and scientific suppression. His story was recently featured in Sunday’s The Washington Post Magazine, Was a USDA Scientist Muzzled Because of His Bee Research, as censorship of federal scientists has grown. As a Senior Research Entomologist and Lab Supervisor for the Agricultural Research Service (ARS) in South Dakota, Dr. Lundgren had worked for USDA for eleven years with great success, with his research drawing national attention and international recognition. However, in October 2015, Dr. Lundgren, represented by Public Employees for Environmental Responsibility (PEER) filed a whistleblower complaint charging the agency with suppression of research findings that challenged the safety and efficacy of a widely used class of pesticides, neonicotinoids. In April 2015, PEER filed […]

(Beyond Pesticides, March 7, 2016) A United Nation’s report, released late last month, has warns the world that many species of wild bees, butterflies and other pollinators are on a dangerous path toward extinction, and that the  food supply will suffer if the causes of these declines, many of them human-made, are not stopped. The report is based on  many different scientific studies. The scientists who led the assessment pointed to pesticides as one of the leading causes of pollinator decline, specifically, a class of toxic chemicals called neonicotinoids, which adversely affect the nervous system of insects. According to their press release, the assessment,  Thematic Assessment of Pollinators, Pollination and Food Production, is the first ever issued by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem  Services (IPBES). IPBES was founded in 2012 with 124 member nations to “form a crucial intersection between international scientific understanding and public policy making.” Before its release, the assessment attracted some controversy for including two representatives from the agrochemical industry, including Bayer CropScience and Syngenta, as lead authors. Even though the IPBES requires all lead authors to complete conflict-of-interest statements, some scientists and environmentalists expressed concern. Given the roll of agrochemicals in pollinator decline, […]

(Beyond Pesticides, March 4, 2016) Honey bees experience a learning and memory deficit after ingesting small doses of the insecticide  chlorpyrifos, potentially threatening their success and survival, according to a study in  New Zealand. Chlorpyrifos is a highly neurotoxic organophosphate pesticide used worldwide on crops to protect against insects and mites. The study,  Measurements of Chlorpyrifos Levels in Forager Bees and Comparison with Levels that Disrupt Honey Bee Odor-Mediated Learning Under Laboratory Conditions,  published in  Ecology, examines chlorpyrifos levels in  bees collected from 17 locations in Otago, New Zealand and compared doses of the pesticide that cause sub-lethal effects on learning performance under laboratory conditions with amounts of chlorpyrifos detected in bees in the field. Researchers found chlorpyrifos in 17% of the sites sampled and 12% of the colonies examined. Honey bees are found to experience harmful effects to smell memory and learning, and reduction in specificity of memory recall. Chlorpyrifos is just one of many pesticides that have frequently been detected in honey bees. According to a study conducted last year by the U.S. Geological Survey (USGS), 72% of bees tested positive for pesticide residues, raising concerns about  unintended pesticide exposures where land uses overlap or are in proximity […]

(Washington, DC, March 1, 2016) After pesticide manufacturer Bayer CropScience would not voluntarily remove from the market the insecticide flubendiamide, the U.S. Environmental Protection Agency (EPA) formally issued a Notice of Intent to Cancel the insecticide, citing its high toxicity to aquatic organisms. Bayer is embroiled in controversy over its neonicotinoid insecticides because, as systemic pesticides, they move through the entire plant and express the poison through pollen and nectar, indiscriminately killing bees and other pollinators and polluting waterways. Flubendiamide, a benzenedicarboxamide pesticide, is “locally systemic” within the plant’s leaves. EPA’s action today may take years of regulatory review and legal action while the pesticide remains on the market. EPA used the controversial conditional registration provision of federal pesticide law, when in 2008 it allowed flubendiamide on the market, despite outstanding environmental data. At the time, it struck an agreement that, if unreasonable adverse effects on the environment were found, Bayer would withdraw the chemical’s registration. Today’s action serves to exemplify the consequences of allowing potentially harmful substances onto the market without all the information necessary to issue a complete finding of environmental and public safety. Because of EPA’s long cancellation process, unless it takes the rare action of finding […]

(Beyond Pesticides, February 29, 2016) Last Thursday, the Munich Environmental Institute stated that it had found traces of glyphosate, the widely used and controversial weed-killer, in 14 of Germany’s most popular beers. These findings are a potential blow to Germany’s Beer Purity Law, which is highly regarded in German beer culture. Industry and German government immediately sought to downplay the results, saying that the levels found did not pose a risk to humans. However, according to the study’s results, all levels found were above the glyphosate residue level allowed in drinking water. Consumers have a right to be worried about the findings, as glyphosate was classified in March 2015  as a probable carcinogen by the International Agency for Research on Cancer (IARC). The results, published  in German, are broken down by beer and by micrograms per liter in picture format. The researchers cite the laboratory test results of the 14 beers, which found glyphosate levels  between 0.46 and 29.74 micrograms per liter. The highest reading is 300 times the legal limit for drinking water in Germany, which is 0.1 microgram per cubic meter. Hasseroeder, a beer brewed in Saxony-Anhalt in eastern Germany and owned by Anheuser Busch Inbev, contained the […]

(Beyond Pesticides, February 18, 2016) Last week, 35 members of Congress, led by Representatives Earl Blumenauer (OR-3) and Peter DeFazio (OR-4), signed a letter to Environmental Protection Agency (EPA) Administrator Gina McCarthy, challenging  EPA’s review process for the  glyphosate  and  2,4-D  herbicide mixture, known as Enlist Duo. It is produced by Dow AgroSciences for use in genetically engineered  crops. The letter requests “more information about EPA’s plan to reevaluate Enlist Duo’s health and environmental risks.” The letter comes just weeks after the 9th U.S. Circuit Court of Appeals denied a request from EPA to vacate its own decision to  approve the  toxic herbicide cocktail. Because of the court’s decision, EPA is solely responsible for the decision about Enlist Duo’s registration. “This is part of a vicious cycle that is leading to more potent, dangerous chemicals being widely used on crops across the United States,” said  Rep. Blumenauer. He continued, “With the rise of herbicide-resistant genetically modified crops, herbicides are more widely sprayed causing weeds to grow more resistant — ultimately, requiring the application of even stronger herbicides. EPA must take action to make sure products entering the market to be used on our food are safe for human health and […]

(Beyond Pesticides, February 12, 2015) A new study published last week asserts a viral epidemic driven by parasitic mites is contributing to the global decline in bees, problematically underplaying the significant impact that bee-toxic neonicotinoid insecticides have on pollinator populations, as supported by a growing body of scientific literature, especially findings that show bees’ increased vulnerability to parasites and viruses. Researchers of the study, titled “Deformed wing virus is a recent global epidemic in honeybees driven by Varroa mites” and published in the journal Science, conclude that the deformed wing virus (DWV), which is typically transmitted through its main vector, the Varroa mite, is globally distributed and recently spread from a common source, European honeybee Apis mellifera. Lead researcher Lena Bayer-Wilfert, PhD, of the University of Exeter, said European bees are at the heart of the global spread of what she calls a “double blow” for colonies. “This is clearly linked to the human movement of honey bee colonies around the globe,” she told BBC News. Co-researcher Professor Roger Butlin of the University of Sheffield said DWV was a major threat to honey bee populations across the world with the epidemic “driven by the trade and movement of honeybee colonies.” […]

(Beyond Pesticides, February 9, 2016) Last week, Bayer CropScience reneged on an agreement with the U.S. Environmental Protection Agency (EPA) to voluntarily cancel the conditionally registered insecticide flubendiamide if  the agency  received  data that  identified adverse ecological effects. Based on the data, EPA found that the chemical causes “unreasonable adverse effects” to benthic organisms living in sediment near agricultural fields. Bayer’s defiance in the face of EPA’s finding  points to  a fundamental  weakness in  the agency’s conditional pesticide registration process, which allows toxic chemicals onto the market without a complete and comprehensive assessment  of their  potential  harm, in this case to  wildlife and the vital ecosystem services they provide. 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 the effect of the chemical and its breakdown product on freshwater benthic invertebrates, species such as crustaceans and aquatic insects that  live in stream sediment and provide important ecosystem services such as decomposition and nutrient cycling. In response, rather than declining to proceed with registration […]

(Beyond Pesticides, February 5, 2016) According to a report published earlier this week, Trends in glyphosate herbicide use in the United States and Globally, glyphosate, manufactured by Monsanto and known by its product name Roundup, is the most widely and heavily applied weed-killer in the history of chemical-intensive agriculture both in the U.S. and globally. Charles Benbrook, Ph.D., author of the study, which was published in the peer-reviewed journal Environmental Sciences Europe, reports that to date 18.9 billion pounds (8.6 billion kilograms) of glyphosate have been used globally, with an estimated 19% of the use coming from the U.S. The report also points out that glyphosate use has risen almost 15-fold since “Roundup Ready” genetically engineered crops (GE) were introduced in 1996. Dr. Benbrook’s research concludes that, “Genetically engineered herbicide-tolerant crops now account for about 56 % of global glyphosate use. In the U.S., no pesticide has come remotely close to such intensive and widespread use.” According to the report, two-thirds of the total volume of glyphosate applied in the U.S. from 1974 to 2014 has been sprayed in just the last 10  years. And, in 2014, enough glyphosate was sprayed to leave more than three-quarters of a pound of […]

(Beyond Pesticides, February 4, 2016) According to a study published in Oxford University Press, entitled High Levels of Resistance in the Common Bed Bug, bed bugs have developed resistance to neonicotinoids (neonics). Neonics have become one of the most widely used active ingredients to control bed bugs since the insects’ have exhibited  resistance to other chemicals, including synthetic pyrethroids.  Troy Anderson, Ph.D., entomologist at Virginia Tech and Alvaro Romero, Ph.D., entomologist at New Mexico State, studies found higher neonic  efficacy for neonics used on lab bed bugs as compared with bed bugs found in domestic settings. With the resurgence of bed bugs across the U.S., exterminators have relied heavily on insecticides to manage the pesky pests, despite questions about efficacy due to resistance, and viability of alternative, non-toxic solutions. To test the tolerance and ineffectiveness of pesticides used on bed bugs, Drs. Anderson and Romero used four popular neonics (imidacloprid, acetamiprid, dinotefuran, thiamethoxam) to compare their effectiveness in wild and isolated bed bug populations. Bed bugs isolated in a lab died quickly from a small amount of neonics, however, those same chemical treatments used on bed bugs found in Cincinnati and Michigan were ineffective. The isolated group of bed bugs […]

(Beyond Pesticides, February 2, 2016) Boulder, Colorado’s McGuckin Hardware is setting an example for hardware stores across the country by removing bee-toxic neonicotinoids from its store shelves, and working to reorient its customers toward natural, holistic practices. McGuckin’s change is the latest in a movement among local hardware businesses to take a stand against toxic pesticides that are harmful to pollinators and unnecessary to control problem pests. “We wanted to be one of the first to get rid of them,” said Steve Wilke, McGuckins marketing communications specialist in a piece published in Hardware Retailing, a newsletter run by the North American Retail Hardware Association. Local and national advocates are praising McGuckin’s shift away from products that harm pollinators. “People are very excited about the dramatic steps McGuckin’s has taken to get neonics out of our environment,” said David Wheeler of the local pollinator-advocacy organization Bee Safe Boulder. Bee Safe Boulder is a coalition of concerned Boulder residents that successfully fought for the passage of a pollinator resolution in the City of Boulder, Layfayette, and Boulder County, Colorado. The organization also has a project aimed at encouraging local retailers to stop selling plants coated in neonicotinoids; 18 retailers in the area, […]

(Beyond Pesticides, February 1, 2016) Last Wednesday, the city council of St. Paul, MN adopted a resolution to make the city more pollinator friendly by banning bee-toxic neonicotinoids and other pesticides “proven  to be harmful to pollinators” and require an  updating of its Integrated Pest Management (IPM) program, prioritizing non-chemical methods. The resolution recognizes that its authority to restrict pesticide use on private land  has been preempted by the State of Minnesota and then directs the city to encourage property owners within its jurisdiction to practice pollinator stewardship. Under the new resolution, St. Paul has committed to: Develop or update an IPM program that requires site inspections, monitoring and prevention strategies, an evaluation on the need for pest control, and when pest control is warranted the use of structural, mechanical, biological, organic, and other nonchemical methods will be utilized first. Eliminate the use of neonicotinoid insecticides, and other pesticides proven to be harmful to pollinators, on city grounds, with specific exceptions for golf course areas and certain athletic fields. Require all city departments with any inventory of materials containing neonicotinoids, and other pesticides proven to be harmful to pollinators, to discontinue their use and properly dispose of them unless a […]

(Beyond Pesticides, January 29, 2016) This week, the 9th U.S. Circuit Court of Appeals handed a victory to Dow Chemical Company and its  efforts to keep the toxic pesticide Enlist Duo on the market, despite new safety concerns identified by the Environmental Protection Agency (EPA).  Enlist Duo has been marketed as a “solution” for the control of glyphosate-resistant weeds in genetically engineered (GE) crops, brought on by the  widespread use of Monsanto’s  Roundup  on glyphosate-tolerant (Roundup Ready) crops over the last decade. EPA asked the court at the end of November, 2015 to vacate its 2014 approval of Enlist Duo based on new information on the  toxic effects associated with the synergistic interactions of  the chemical cocktail of 2,4-D, glyphosate, and other undisclosed ingredients in the product to plants outside the treated area, including endangered plants. The three-sentence order, which does not include  the judge’s reasoning, denied EPA’s request. While considering other legal options, EPA can choose  to exercise it administrative powers by  canceling specific uses or the entire  registration of Enlist Duo under  its pesticide cancellation process, and within that process could choose to identify an imminent hazard and remove the pesticide from the market immediately, while it faces […]

(Beyond Pesticides, January 25, 2016) Monsanto filed a lawsuit in California last week seeking to prevent glyphosate, the main ingredient in its Roundup herbicide, from being added to California’s  list of known carcinogens under the state’s Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). Glyphosate is  classified  as a probable carcinogen by the World Health Organization’s International Agency for the Research of Cancer (IARC) based on sufficient  evidence  of carcinogenicity in experimental animals. This is the highest level carcinogen based on laboratory animal studies  under  IARC’s rating system. California law requires the state to keep a list of cancer-causing chemicals to inform residents of their risks. California Office of Environmental Health Hazard Assessment (OEHHA) said in September that it planned to add glyphosate to the list after the World Health Organization’s International Agency for Research on Cancer (IARC) classified it as a probable human carcinogen last March. Monsanto has disputed the assessment, citing decades of studies deeming glyphosate safe, including a 2007 study by OEHHA that concluded the chemical was unlikely to cause cancer. The agrochemical company said it filed the suit against the state’s OEHHA, citing the agency’s acting director, Lauren Zeise, in California state court, […]

 (Beyond Pesticides, January 20, 2016) Aldi Süd, the German supermarket chain with stores in the U.S., has become the first major European retailer to ban pesticides toxic to bees, including the neonicotinoids imidacloprid, clothianidin and thiamethoxam, from fruits and vegetables produced for their stores. Aldi has requested suppliers comply at the earliest possible time. In light of the growing pollinator crisis and due to public pressure, retailers in Europe and the U.S. are slowly beginning to make the switch away from bee-toxic pesticides. Beginning January 1, suppliers of fruits and vegetables to Aldi suppliers will have to ensure that their cultivation practices do not include the following eight pesticides identified as toxic to bees (thiamethoxam, chlorpyrifos,  clothianidin, cypermethrin, deltamethrin, fipronil, imidacloprid and sulfoxaflor) to meet  the new requirement. According to a press release from Greenpeace, the chemicals are used on various commodities in Europe  —thiamethoxam (used in lettuce and endive), chlorpyrifos, clothianidin (used in kohlrabi, herbs, Brussels sprouts, head cabbage, cauliflower and kale), cypermethrin (leek, head cabbage and leguminous vegetables), deltamethrin (cauliflower, peppers, eggplant, zucchini, cucumber, pea, head cabbage, tomato and lettuce),  imidacloprid (applied to apples, peaches, apricots and lettuce). Sulfoxaflor was recently granted regulatory approval in Europe, despite calls […]

(Beyond Pesticides, January 14, 2016) Bayer CropScience, revising its stance,  has decided to concur with the  Environmental Protection Agency’s (EPA) preliminary risk assessment of neonicotinoids and acknowledge the finding of harm to honey bees in certain crops. A spokesman for Bayer CropScience said the neonic-selling giant has reviewed the assessment and found it to be “quite good and scientifically sound,” according to a news report.  The Guardian  is reporting that Bayer will be proposing new protections for pollinators, however the company has not yet announced what the new protections will be. This is a stark turnaround from  Bayer’s statement last week, which said EPA’s assessment “appears to overestimate the potential for harmful exposures in certain crops, such as citrus and cotton, while ignoring the important benefits these products provide and management practices to protect bees.” Last week, EPA released its preliminary honey bee risk assessment for one of the most widely used neonicotinoids, imidacloprid, which is  linked to severely declining honey bee populations. The assessment found  harmful residues of the insecticide  in crops where the pollinators forage  and confirmed bees’ widespread and sustained exposure to the highly toxic and persistent chemical through poisoned pollen and nectar. Imidacloprid, like the other […]

(Beyond Pesticides, January 13, 2016) Last Friday, the Willapa Grays Harbor Oyster Growers Association (WGHOGA) in Washington State sent a 71-page request to the Washington Department of Ecology (Ecology) asking state regulators to approve  a permit to  spray neonicotinoid insecticides  that are having devastating effects on the ecosystems worldwide. Yet, WGHOGA is pursuing a single-minded approach to chemically control the shrimp that are hurting their oyster crops, while using chemicals that the preponderance of science finds cause ecosystem imbalance. In  April 2015, much to the dismay of activists and concerned local residents, Ecology approved a permit for the use of imidacloprid (a neonicotinoid) to combat a growing native population of burrowing shrimp that threatens  valuable shellfish (oyster) beds in Willapa Bay and Grays  Harbor. But, with a  nationwide public outcry, the permit was withdrawn in May 2015. Ecology sent KING 5, a local Washington news agency, the below statement last Friday: “We received the permit application this morning from the Willapa Grays Harbor Oyster Growers Association to use imidacloprid on shellfish beds. It will take some time for us to review the 71-page application. On May 3 (2015) the Oyster Growers Association asked Ecology to withdraw their permit. Since then, […]

(Beyond Pesticides, January 11, 2016) Scientists at Sussex University in the United Kingdom (UK) have found that bumble bees and honey bees are exposed to a harmful chemical cocktail when collecting pollen from wildflowers and hedgerows that border neonicotinoid-treated crops in UK farmland. After testing oilseed rape croplands during blooming season, these chemical cocktails were found to be mixed with fungicides and insecticides, and at concentrations much higher than expected.  According to the Soil Association, which supported the study, “These chemical cocktails could make the impact of neonicotinoids up to 1,000 times more potent than previously realized.” With at least 121 different agrochemicals detected in hive wax and pollen samples in the Unites States, most of which include systemic pesticides, it is becoming increasingly more important to study the synergistic effects of pesticides in and outside of farm land. The study focused on “determining which mixtures of commonly used fungicides occur alongside neonicotinoids” and found that all individual oilseed rape pollen samples contained at least six neonicotinoid and fungicide residues. To compare, three neonicotinoid and six fungicides were detected in wildflower pollen samples. While the wildflower contamination was expectedly lower than crop contamination, the rate of bee contamination paints a […]
