Bill to Ban Neurotoxic Chlorpyrifos Introduced in the U.S. Senate

Thursday, July 27th, 2017

(Beyond Pesticides, July 27, 2017) Earlier this week U.S. Senators Tom Udall (D-NM) and Richard Blumenthal (D-CT) introduced a bill that would ban use of the insecticide chlorpyrifos. The Protect Children, Farmers and Farmworkers from Nerve Agent Pesticides Act, S. 1624, comes one week after an appeals court refused to require the U.S. Environmental Protection Agency (EPA) to make a decision over whether to ban the chemical. Removing this neurotoxic insecticide from the environment would significantly reduce health risks for children and farmworkers in underserved rural communities, build pressure to address all toxic organophosphates, and help push U.S. agriculture in a more sustainable direction. As with other organophosphate class chemicals, chlorpyrifos, first registered in 1965 by Dow Chemical, is derived from nerve agents used during World War 2. The chemical is linked to a range of negative health and environmental outcomes that warrant its prohibition. Children are at particular risk from the chemical due to their developing immune, organ, and nervous systems.  As with other organophosphate nerve agents, the chemical acts on the body’s nervous system, inhibiting the movement of neurotransmitters called cholinesterase. Chlorpyrifos chemically binds to the site where cholinesterase would in the body, preventing normal nerve impulse transmission. […]

EPA Rejects Pesticide Use in Cannabis Production, Paves Way for Organic Marijuana

Tuesday, July 25th, 2017

(Beyond Pesticides, July 25, 2017) With the legalization of medical and recreational marijuana in dozens of states, the question of pesticide use in commercial cannabis production and resulting residues in a range of products is a burning issue. The U.S. Environmental Protection Agency (EPA) injected itself into this question when last week it issued a notice of intent to disapprove the planned registration of four pesticides for cannabis production by the state of California. Given cannabis’ narcotic status by the federal government, EPA does not register pesticides for use in marijuana production. However, states and previously EPA have considered using a Special Local Needs (SLN) permit under the nation’s pesticide law, the Federal Insecticide Fungicide and Rodenticide Act (Section 24c), to allow this unregistered pesticide use to meet an “existing or imminent pest problem.” While reports suggest that EPA’s rejection is likely politically motivated based on the current administrator’s opposition to cannabis legalization in general, the agency’s determination is consistent with Beyond Pesticides’ letters to states and EPA, which encourage the burgeoning industry to root itself in organic production, without the use of toxic pesticides. “The cannabis industry has the opportunity to develop with organic soil management and fertility practices that […]

Urgent/by Monday: Help Stop Bee-Toxic Neonicotinoid Pesticides from Killing Bees and Contaminating Waterways!

Thursday, July 20th, 2017

(Beyond Pesticides, July 20, 2017) In its recently released 2017 Preliminary Aquatic Risk Assessment for Imidacloprid, the U.S. Environmental Protection Agency (EPA) found that this neonicotinoid insecticide is not only toxic to bees but also, is destroying life in the nation’s streams, rivers, and lakes. This assessment finds that aquatic invertebrates, especially aquatic insects basic to aquatic food chains, are sensitive to imidacloprid, and that current imidacloprid levels detected in streams, rivers, lakes, and drainage canals exceed acute and chronic toxicity endpoints. Impacts occur at low concentrations, and can result in decreased species abundance, altered predator-prey relationships, and reduced nutrient cycling. Impacts to other wildlife that depend on these species raise serious cause for concern. Comment by July 24 and tell EPA to cancel these neonicotinoids to protect sensitive species and ecosystems. See sample comment language, below. Clothianidin, thiamethoxam, and dinotefuran are too toxic for honey bees and native bees EPA also finds that the other neonicotinoids –clothianidin, thiamethoxam, and dinotefuran– pose risks to bees both on and around treated fields, but the agency has not evaluated risks from soil, surface water, or contaminated seed dust, which underestimates exposure risks and continues to put our native bees at risk. Clothianidin and thiamethoxam are […]

Pesticide Caused Disruption of Ecological Balance Increases Parasitic Disease`

Wednesday, July 19th, 2017

(Beyond Pesticides, July 19, 2017) Research connects a healthy environment to overall public health, linking diseases to pesticide caused disruption of ecological balance. A new study, published by University of South Florida scientist Jason Rohr, PhD and colleagues, finds that the use of agricultural chemicals, predominantly in developing countries, is associated with increases in transmission risk for schistosomiasis, a disease caused by infection from a parasitic flatworm that lives in freshwater snails. The findings point to the need for an increased focus on alternative pest management approaches that promote, rather than degrade natural ecological services. Previous research published by Dr. Rohr and colleagues found that amphibians exposed to pesticides had higher rates of parasitic infection, and increased fertilizer use resulted in an increase in algae that snail parasite hosts feed on. For the current study, researchers investigated the human epidemiologic risks associated with common farm chemicals. To investigate pesticide effects on the ecosystem, scientists used mesocosms, an experiment designed in a controlled outdoor environment that replicates natural conditions. Algae, parasite-carrying snails, and snail predators (crayfish and water bugs) were added to a series of 60 tanks set up by researchers. The ecological effects of introducing chemical fertilizer, the herbicide atrazine, and insecticide chlorpyrifos […]

Washington Oyster Growers Request Approval to Apply Neonicotinoid in Aquatic Environments

Thursday, July 6th, 2017

(Beyond Pesticides, July 6, 2017) The Washington State Department of Ecology (Ecology) is evaluating a new permit application for the use of imidacloprid, a toxic neonicotinoid, to combat a growing native population of burrowing shrimp that threatens oyster beds in Willapa Bay and Grays Harbor in Washington state. The application was recently submitted to Ecology by a group of oyster farmers from the Willapa Grays Harbor Oyster Growers Association (WGHOGA), who “propose to use the pesticide to treat tide lands to support their aquaculture practices.” Imidacloprid is known to be toxic to bees and aquatic organisms, raising questions on the impacts of its use on the long-term ecological health of the bays. In April 2015, much to the dismay of activists and concerned local residents, Ecology approved a permit submitted by oyster farmers for the use of imidacloprid to combat burrowing shrimp in these aquatic ecosystems. But with a nationwide public outcry, the permit was withdrawn in May 2015. The recent request that was submitted differs in several ways from this 2015 permit, including: The new permit proposes treating 485 acres in Willapa Bay and 15 acres in Grays Harbor, compared to 2,000 acres combined from both water bodies in the 2015 permit. The oyster farmers […]

Polli-NATION Pollinator of the Month: The Hoverfly

Wednesday, July 5th, 2017

(Beyond Pesticides, July 5, 2017) The Hoverfly is July’s pollinator of the month. Hoverflies, also known as flower flies and syrphid flies, are members of the “true fly” order Diptera, family Syrphidae. There are roughly 200 genera and 6,000 species of hoverflies throughout the world. Range Hoverflies are commonly seen in in flowering landscapes across the globe. According to the United States Forest Service (USFS), there are almost 900 species of the family in North America. They live in a range of habitats, including decaying wood, still and moving freshwater, on plants, and sometimes even in other insects’ nests. They are not often found in desert regions, and no known species have been discovered in Antarctica. Diet and Pollination The diet of hoverflies varies widely among species. In general, they are vital pollinators for a range of common flowering plants. Most adult flower flies have generalized mouthparts structured to sap up nectar and harvest pollen from open flowers; others use a long, beak-like proboscis to imbibe nectar from tube-shaped flowers; and some reportedly feed on the honeydew secreted from aphids. Because certain syrphid flies will feed on human perspiration, they are often mistaken for sweat bees. Unlike sweat bees, however, […]

Largest Field Study Finds Neonicotinoids Decimate Bees

Monday, July 3rd, 2017

(Beyond Pesticides, July 3, 2017) A two-year long study conducted at 33 sites in multiple European countries to assess the effects of neonicotinoid (neonics) insecticides on three bee species in real-world environmental conditions confirms that these pesticides have a deleterious effect on bee survival. The study, the largest of its kind, explored the role of the agricultural use of neonics as seed coatings on bee health and fnds that the pesticides are persistent in the environment, contaminating pollen and nectar that bees forage, reducing colony fitness. The results of the study support ongoing calls for a ban on neonics, including a European Union (EU) wide ban proposed earlier this year. The new research, published in the prestigious peer-review journal Science, which was in part funded by Bayer and Syngenta – manufacturers of the pesticides, encompassed large field experiments to assess the effects of neonic-treated crops on various bee species –honey bees (Apis mellifera), bumble bees (Bombus terrestris), and solitary bees (Osmia bicornis)– across three European countries (Germany, Hungary and the United Kingdom). The study examines the impacts of clothianidin and thiamethoxam, the neonics frequently used as seed coatings of oil seed rape (canola), and used in the fields under study. […]

French Prime Minister Retains Bee-Toxic Neonicotinoid Pesticide Ban

Tuesday, June 27th, 2017

(Beyond Pesticides, June 27, 2017) French Prime Minister, Edouard Philippe, is retaining the neonicotinoid (neonic) pesticide ban, which is set to go into effect in 2018 and is stronger than the current European Union restrictions on neonics. This decision follows a disagreement with French Agriculture Minister, Stephane Travert, who was in favor of relaxing the ban and told media outlets that he wants to address “the possibility of a number of exemptions until we find substitution products.” In July 2016, lawmakers in France approved plans to ban neonicotinoid pesticides by 2018, based on their link to declining populations of pollinators, specifically bees. 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 to protect biodiversity. In March 2017, the European Commission (EC) proposed a complete ban of agricultural uses of the widely used bee-toxic neonicotinoid pesticides across Europe under draft regulations. The EC cites neonicotinoids’ “high acute risks to bees.” In 2013, three neonicotinoids were temporarily banned because of concerns about their high toxicity to bees. A vote by member states is still being awaited. In 2013, the European Commission voted to suspend the use of the neonicotinoid pesticides […]

Inspector General: EPA Must Evaluate Impact of Chemical Mixtures

Monday, June 26th, 2017

(Beyond Pesticides, June 26, 2017) A new report released last week by the U.S. Environmental Protection Agency’s (EPA) Office of the Inspector General finds that the agency must collect and assess information on chemical mixtures and potential synergistic effects in order to improve oversight over pesticide registrations and management of developing herbicide resistance. Synergy results when the mixture of chemicals creates effects greater than the aggregation of individual effects, leading to underestimated toxic impacts on human and environmental health. EPA’s Office of Chemical Safety and Pollution Prevention states it will consider how best to use synergistic effects data for pesticide registration decisions by 2019. The report, released June 21, 2017, EPA Can Strengthen Its Oversight of Herbicide Resistance With Better Management Controls, is the result of an assessment into EPA’s management and oversight of resistance issues related to herbicide-resistant genetically engineered (GE) crops. The report finds, “EPA uses the pesticide registration process to collect information on human health and environmental risks from pesticides used on herbicide-resistant weeds, but no information is collected regarding synergism.” It states that information on synergy is important because it allows EPA “a greater ability to assess human health and environmental risks combined with real-world pesticide […]

Polli-Nation Pollinator of the Month: Hawk Moth

Thursday, June 1st, 2017

(Beyond Pesticides, June 1, 2017) The hawk moth is the pollinator of the month for June. Hawk moth is the common name for Sphingidae, a family of over 1,400 moth species. They are also commonly referred to as sphinx moths. This family is divided into two subfamilies, five tribes, and 205 genera. The voracious tomato hornworms and tobacco hornworms are larvae of two hawk moth species. Range According to a study by the University of Nebraska, hawk moths can be found in all parts of the world except Greenland. Some areas only host these moths for part of the year because many species make seasonal migrations to find reliable food sources and to breed. The study notes that some hawk moth species can even be found in Antarctica and the North Pole. Diet and Pollination The hawk moth drinks nectar from sweet-smelling flowers, many of which bloom at night. Most hawk moth species have a long proboscis. This hollow, tongue-like appendage is used to access nectar deep inside flowers. The family has the longest tongues in the moth and butterfly order. In some species, the proboscis reaches over a foot in length. These impressive tongues allow the moths to feed […]

Neonicotinoid Seed Coatings Create Exposure Hazards for Honey Bees and Fail to Increase Yields

Wednesday, May 31st, 2017

(Beyond Pesticides, May 31, 2017) Neonicotinoid-treated corn seeds produce lethal and sub-lethal exposure risks to honey bees and do not increase yields for farmers, according to a recent study by researchers at Purdue University. The study, published in the Journal of Applied Ecology, Planting of neonicotinoid-treated maize poses risks for honey bees and other non-target organisms over a wide area without consistent crop yield benefit, examines neonicotinoid (neonic) dust drift during corn planting in Indiana and the likelihood of honey bee exposure during foraging. The study results and subsequent analysis using public data of apiary locations indicate that over 94% of honey bee foragers in Indiana are at risk of exposure to varied levels of neonics, including lethal levels, during corn sowing. Researchers also performed a three-year field assessment of the purported benefits from neonic seed coatings for pest management, finding that there is no evidence of increased corn yields compared to sites with no neonic seed treatments. According to the lead author of the study, Christian Krupke, Ph.D., in an interview with Purdue Extension, “There was a misconception that any bees not living near corn were likely to be fine. But that’s not true, and it’s clear that these […]

Beekeepers Continue to Experience Significant Losses as Pollinator Crisis Moves into 11th Year

Tuesday, May 30th, 2017

(Beyond Pesticides, May 30, 2017) U.S. beekeepers lost an unsustainable 33% of their hives over the past year, according to new data from the Bee Informed Partnership. While this year’s numbers are lower than those recorded last year, which found nearly half of U.S. honey bee colonies died off, there is no cause for celebration. Declines are still well above acceptable loss rates of 15% or less, and the data indicate a continuing trend of substantial losses during the summer months. Without real changes to U.S. policy that effectively eliminate pollinator exposure to highly toxic and persistent pesticides such as neonicotinoids, there is little likelihood that these unsustainable losses will subside. Despite the overall dour projections for U.S. pollinators, Bayer, the major manufacturer of neonicotinoid pesticides implicated in pollinator declines, attempts to spin the news in its favor. Last week, the company put out a press release titled “Welcome News for Honey Bees,” and went on the praise itself for its efforts to protect pollinators. The chemical industry continues to use public relations tactics, in a similar vein to those previously employed by the tobacco industry, to downplay the nature of the crisis, spin the science, and blame everything but […]

U.S. House of Representatives Votes to Rollback Waterway Protections

Friday, May 26th, 2017

(Beyond Pesticides, May 26, 2017) On Wednesday, the U.S. House of Representatives voted to pass a bill that would reverse an Environmental Protection Agency (EPA) requirement to obtain a permit before spraying pesticides on or near waterways. The passage of HR 953, The Reducing Regulatory Burdens Act (known by environmentalists as the “Poison Our Waters Act”), is the latest update in a multi-year string of attempts to rollback commonsense protections for the public waterways all Americans use for swimming, fishing, and other forms of recreation. It will now move forward to be considered by the Republican-majority Senate, where it will most likely pass and be signed into law. HR 953, if signed into law, would reverse a 2009 decision issued by the 6th Circuit Court of Appeals, in the case of National Cotton Council et al. v. EPA, which held that pesticides applied to waterways should be considered pollutants under federal law and regulated under the Clean Water Act (CWA), through National Pollutant Discharge Elimination System (NPDES) permits. Prior to the decision, the EPA, under the Bush Administration, had allowed the weaker and more generalized standards under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) to be followed. This allowed pesticides to be discharged […]

Maui County Kicks Off Pesticide-Free Pilot Program to Transition to Organic Management

Thursday, May 25th, 2017

(Beyond Pesticides, May 25, 2017) Four parks in Maui, Hawaii, have kicked off a year-long pesticide-free pilot program to transition to organic management. A series of training events in the county over the past few weeks focused on soil-based approaches to land management, a more effective solution than solely switching from synthetic to organic pesticides. Last Wednesday, Beyond Pesticides’ executive director, Jay Feldman, and Chip Osborne, president of Osborne Organics, taught training sessions with county Parks and Recreation staff, “discussing lawn care that relies less on outside products and aims to feed the soil, not just the plant.” Beyond Pesticides worked to support the pesticide-free parks movement in Maui by sponsoring these training sessions for Maui County Parks, Department of Transportation, Maui public schools, several local resorts, and golf course management groups. Beyond Pesticides is working with Maui County to provide guidance on transitioning its parks to organic practices. Analysis of soil samples at each site has been conducted, which will provide a baseline to implement cultural changes to improve the biological health of the soil, making it more resistant to weed and insect pressures. The next step includes creation of a report and action plan for each county park by Beyond Pesticides and Osborne […]

Soft Drink Company Faces Pressure Over Use of Pesticides in its Supply Chain

Thursday, May 18th, 2017

(Beyond Pesticides, May 18, 2017) A pesticide reduction plan proposed by investors in the Dr. Pepper Snapple Group (DPS) lacks a positive vision that could accomplish the investors’ goals. The shareholder proposal at DPS, which makes Mott’s, 7UP, Snapple, and Canada Dry, was filed by the Green Century Equity Fund, a company that offers environmentally and socially responsible mutual funds, seeks to pressure DPS to reduce toxic pesticide use in its supply chain. According to their press release, the shareholder proposal suggests that DPS “use quantitative metrics to track the amount of pesticides avoided, publish goals to reduce pesticide use or toxicity, and/or provide incentives to growers to minimize the use of pesticides.” However, the shareholder group could better achieve its goals by asking that DPS use certified organic ingredients. Beyond Pesticides has long sought a broad-scale marketplace transition that does not simply reduce or minimize pesticide use, but prohibits the application of toxic synthetic pesticides by law and promotes the widespread transition of conventional farmland to organic production, which is protective of health and the environment. Certified organic production, with its requirement of a detailed organic system plan and methods to foster and improve soil health, achieves the elimination […]

Judge Rules that EPA Neonicotinoid Registrations Violated Endangered Species Act

Thursday, May 11th, 2017

(Beyond Pesticides, May 11, 2017) On Monday, a federal judge in California ruled that the U.S. Environmental Protection Agency (EPA) violated the Endangered Species Act (ESA) when it issued 59 neonicotinoid insecticide registrations between 2007 and 2012 for pesticide products containing clothianidin and thiamethoxam. The original lawsuit against EPA, Ellis v. Housenger, was filed in March 2013, by beekeeper Steve Ellis and a coalition of other beekeepers and environmental groups, including Beyond Pesticides. The 2013 lawsuit focused on the EPA’s failure to protect pollinators from dangerous pesticides and challenged EPA’s oversight of the bee-killing pesticides, clothianidin and thiamethoxam, as well as the agency’s practice of “conditional registration” and labeling deficiencies. According to George Kimbrell, Center for Food Safety’s legal director and the lead plaintiffs’ counsel, “This is a vital victory. Science shows these toxic pesticides harm bees, endangered species and the broader environment. More than fifty years ago, Rachel Carson warned us to avoid such toxic chemicals, and the court’s ruling may bring us one step closer to preventing another Silent Spring.” The judge presiding over the case rejected claims by pesticide producers and their supporters that the plaintiffs failed to establish a causal link between the pesticides and the […]

Walmart and True Value Pledge to Phase Out Bee-Toxic Pesticide

Friday, May 5th, 2017

(Beyond Pesticides, May 5, 2017) Walmart and True Value have announced that beginning on Wednesday they will be phasing out neonicotinoid (neonic) pesticides from all retail supply chains. These announcements follow numerous scientific studies that have consistently implicated neonics in the decline of honey bees and other wild pollinators. The decision stems from an ongoing consumer and environmental campaigns urging retailers to stop selling plants treated with neonics and to remove products containing them from store shelves. Neonicotinoids are systemic pesticides, or whole plant poisons, taken up by a plant’s vascular system and expressed in the pollen, nectar, and dew drops. They are also highly persistent, with research showing the potential for certain chemicals in the class, such as clothianidin, to have a half-life of up to 15 years. Studies show significant cause for concern when it comes to pollinators and exposure to these pesticides. Although little substantive action on these chemicals has been taken by the U.S. Environmental Protection Agency (EPA), the agency agreed that the pesticides do harm bees, though only in the limited situations and constrained scenarios that were actually investigated by EPA. The European Commission (EC) has proposed a complete ban of agricultural uses of the widely used […]

Bumblebee Exposure to Neonicotinoid Pesticide Reduces Egg Development

Thursday, May 4th, 2017

(Beyond Pesticides, May 4, 2017) This week, a study released in the Proceedings of the Royal Society found evidence of reduced egg development and impact on feeding behavior in wild bumblebee queens after exposure to the neonicotinoid thiamethoxam. The study, led by researchers from the University of London, investigates the impact of field-relevant levels of thiamethoxam exposure on four wild species of bumblebee queens. In a BBC News article, lead author, Dr. Gemma Barron, Ph.D., stated, “We consistently found that neonicotinoid exposure, at levels mimicking exposure that queens could experience in agricultural landscapes, resulted in reduced ovary development in queens of all four species we tested. These impacts are likely to reduce the success of bumblebee queens in the spring, with knock-on effects for bee populations later in the year.” The study focuses on sublethal effects of neonicotinoids, as wild bumblebees are more likely to be exposed to low doses of these chemicals, rather than higher lethal levels. The queen bumblebees of four species were collected in the spring of 2014, with a total of 506 being used in the initial study groups. These queens were divided into three treatment groups and exposed to either a high level, low level, or no […]

Neoniocotinoid Pesticides Impair Bees’ Ability to Fly

Wednesday, May 3rd, 2017

(Beyond Pesticides, May 3, 2017) Last week, researchers at the University of California San Diego revealed the first ever link between the use of neonicotinoid pesticides and the ability of bees to fly. Published in Scientific Reports, the study, “A common neonicotinoid pesticide, thiamethoxam, impairs honey bee flight ability,” builds on previous findings that neonicotinoid use interferes with bees’ ability to navigate, and concludes that exposure to thiamethoxam affects honey bee flight patterns as well as their physical ability to fly in ways that may be detrimental to their survival. The study is the latest in a growing body of science linking pesticide use to honey bee declines, raising concerns about overall honey bee health and longevity in the face of continued neonicotinoid use. According to the study, both acute and chronic exposure to thiamethoxam revealed significant alterations of the ability of bees to fly -affecting flight distances, duration of flights, and flight velocity. Researchers noted significant differences in bee behavior based on short versus long term exposure, which they summarized as having an “excitatory short-term effect and a depressive longer-term effect” on the bees’ ability to fly. This means that when bees were exposed to thiamethoxam for a short, […]

Polli-Nation Pollinator of the Month: Mexican Long-tongued Bat

Tuesday, May 2nd, 2017

(Beyond Pesticides, May 2, 2017) The Mexican long tongued bat is the pollinator of the month for May.  The Mexican long tongued bat, scientific name Choeronycteris mexicana, is a species of bat aptly named for its tongue, which has the remarkable ability to extend to nearly a body length. It is less-commonly referred to as the hog-nosed bat. Range The Mexican long-tongued bat’s range extends from the southwest of the United States through Mexico and into Central America, according to the International Union for Conservation of Nature (IUCN). In the United States, the bat is restricted to the far-south of California, Arizona, Nevada, New Mexico, and Texas. It is found in most areas of Mexico but is absent from the Yucatan peninsula and the gulf coast. Further south, the bat is also found in southern Guatemala and El Salvador in addition to northern Nicaragua. The Mexican long-tongued bat participates in seasonal migrations rather than hibernation. The Texas Parks and Wildlife Department admits that the study of the bat’s migratory patterns has been inadequate. However, it is known that the females establish maternity roosts in the southwest of the United States in late spring. They and their young depart for Mexico […]

Chemical Companies Knowingly Allowed Carcinogenic Contaminant in Common Pesticide

Thursday, April 27th, 2017

(Beyond Pesticides, April 27, 2017) Multinational chemical companies Dow Chemical Company and Shell Chemical Company knowingly sold and marketed fumigants contaminated with a cancer-causing chemical that had a strong propensity to leach into and remain in groundwater, according to a recent report from the Environmental Working Group (EWG) and a lawsuit against the companies. The contaminant of concern, 1,2,3-trichloropropene (TCP), was a manufacturing by-product found in Dow’s Telone and Shell’s D-D fumigant pesticide products with the active ingredient 1,3-Dichloropropene. The products, used to kill soil-dwelling nematodes, are toxic in their own right, but contained TCP in their formulation from the 1940s until the mid-1980s. EWG’s report details widespread contamination of drinking water in California’s agricultural regions, with detections found in 562 wells, and 94 public water systems identifying TCP above legal limits. Thirty-seven additional public water systems serving nearly 4 million U.S. residents throughout the country were also found to contain TCP. The U.S. Environmental Protection Agency has never set maximum contaminant levels for TCP in drinking water, but requires public reporting above the infinitesimally small amount of 30 parts per trillion, roughly six times higher than what the state of California requires. However, even proposed limits of 5 parts per trillion […]

Study Finds Substantial Risks to Honey Bees During and After Crop Pollination

Tuesday, April 25th, 2017

(Beyond Pesticides, April 25, 2017) Past use of agricultural pesticides puts honey bees at risk across multiple growing seasons, according to research from scientists at Cornell University in New York. According to lead author Scott McArt, PhD, “Our data suggest pesticides are migrating through space and time.” Honey bees, which over the past decade have experienced unsustainable declines over 40% each year, are at great risk from exposure to a range of pesticides, chiefly the neonicotinoid class of insecticides. This new research adds to calls from beekeepers, environmental groups, and progressive farmers to transition agriculture away from pesticide-dependent practices. Cornell researchers conducted a massive study that analyzed both the pollen source and pesticide residue found therein for 120 experimental hives placed near 30 apple orchards in New York State. The landscapes surrounding each orchard were classified based on the amount of natural area or agricultural land that was present. Scientists analyzed risk to honey bees by collecting information about pesticide use during the growing season as well as the amount of pesticide contamination in “beebread,” pollen tightly packed unto pellets by bees used as food or in the production of royal jelly. “Beekeepers are very concerned about pesticides, but there’s […]

Report Documents Threats to Aquatic Life, Calls for Phase-Out of Neonicotinoid Use

Friday, April 14th, 2017

(Beyond Pesticides, April 14, 2017) – As pollinators nationwide suffer severe declines tied to widespread exposure to pesticides, particularly a family of insecticides known as neonicotinoids, a new report details the chemicals’ dramatic impacts on aquatic ecosystems and biodiversity. This report coincides with findings of neonicotinoids in drinking water. The new report, Poisoned Waterways, documents the persistence of neonicotinoids in U.S. waterbodies and the danger they cause to aquatic organisms, resulting in complex cascading impacts on aquatic food web. The report supports previous calls for the restriction of neonicotinoid pesticides, given their high toxicity to bees, and now aquatic life. In an early 2017 U.S. Environmental Protection Agency (EPA) risk assessment on one of the most widely used neonicotinoids, the agency reported levels in streams, rivers, lakes and drainage canals that routinely exceed acute and chronic toxicity endpoints derived for freshwater invertebrates. Poisoned Waterways reviews the current scientific literature on the effects of neonicotinoids in waterways and the life they support. Not only are these insecticides, which include, imidacloprid, clothianidin, and thiamethoxam, regularly detected in waterbodies in the U.S., they are found at levels that harm sensitive aquatic organisms. Aquatic insects and crustaceans are highly vulnerable, with the mayfly identified […]
