Court Victory on Three Dicamba Weed Killers Underscores the Need to Reform Pesticide Law

Wednesday, June 17th, 2020

(Beyond Pesticides, June 17, 2020) The June 3 decision in a high-profile “dicamba case” — against the U.S. Environmental Protection Agency (EPA) and for the plaintiffs, a coalition of conservation groups — was huge news in environmental advocacy, agriculture, and agrochemical circles. The federal Ninth Circuit Court of Appeals vacated EPA’s 2018 conditional registration of three dicamba weed killer products for use on an estimated 60 million acres of DT (dicamba-tolerant through genetic modification/engineering) soybeans and cotton. There is, however, a related issue that accompanies this and many other pesticide cases. When EPA decides to cancel or otherwise proscribe use of a pesticide (usually as a result of its demonstrated toxicity and/or damage during litigation), the agency will often allow pesticide manufacturers to continue to sell off “existing stocks” of a pesticide, or growers and applicators to continue to use whatever stock they have or can procure. Beyond Pesticides has opposed, covered, and litigated against this practice. To greenlight predictable harm is a violation of any recognized moral code, never mind of the agency’s mission — “to protect human health and the environment.” According to Beyond Pesticides, EPA should never permit continued use of a dangerous pesticide once that compound’s […]

Take Action: EPA Considers “Emergency” Pesticide Use with Bee-Toxic Pesticide for 10th Year in a Row

Monday, June 8th, 2020

(Beyond Pesticides, June 9, 2020) EPA has received applications from the states of Maryland, Pennsylvania, and Virginia for the “emergency” use of the bee-toxic neonicotinoid insecticide dinotefuran to control brown marmorated stinkbugs in pome and stone fruits. These three states (and others) have received emergency exemptions for this use for the nine previous years and it must not be allowed for a tenth year. Rather than skirt the regulatory process of review, this use pattern must be subject to EPA registration review in combination with all other neonicotinoid uses. Sign the Petition to EPA and Send a Letter to Your Congressional Representative and Senators: EPA Must Deny Routine “Emergency” Exemptions As a neocotinoid insecticide, dinotefuran presents an alarming hazard to bees and other pollinators. Like other neonicotinoids, it is systemic and can indiscriminately poison any insects feeding on nectar, pollen, or exudates. It is also highly toxic to aquatic invertebrates and soil organisms, as well as being highly persistent. In addition to the serious ecological impacts, dinotefuran is toxic to the immune system. This is, of course, an effect that should avoided during the coronavirus pandemic—when the immune system is under attack. Section 18 of the federal pesticide law (FIFRA—Federal Insecticide, Fungicide, […]

EU Proposes 2030 Goal to Reduce Pesticide Use by 50% and Increase Arable Land in Organic Production by At Least 17%

Tuesday, May 26th, 2020

(Beyond Pesticides, May 26, 2020) Across the pond, the European Commission (EC) has announced plans to protect biodiversity and build a more sustainable food system, and identified the reduction of pesticide use  and the expansion of organic agriculture as pillars of the scheme. The EC expects that the initiative, which will require EU member states’ endorsement, will advance progress on the EU goal of eliminating greenhouse gas emissions by 2050, given that 10% of emissions arise from the agricultural sector. The EC’s goals are important and laudable, but Beyond Pesticides is clear: reduction of pesticide use in service of them is not an adequate strategy to ensure long-term success. Genuine success requires the elimination of the use of synthetic chemical pesticides, fertilizers, and other toxic inputs, and the transition to agricultural and land management systems that work with nature, rather than fight against it. Regenerative, organic practices are the path to a livable future, according to Beyond Pesticides. The EC, which is the executive branch of the EU, expects its plan to reduce use of pesticides by 50% by 2030; reduce use of antimicrobial chemicals, including antibiotics, in fish and animal farming by 50%; dedicate a minimum of 25% of arable […]

What’s on My Seeds? Study Finds Most Don’t Know What Pesticides Coat the Seeds They Plant, including Bee-Toxic Neonicotinoids

Tuesday, March 31st, 2020

(Beyond Pesticides, March 31, 2020) Adding to the widespread and problematic use of neonicotinoid pesticides as seed treatments, a recent study published in BioScience finds that there are significant knowledge gaps among some farmers about the seeds they are planting. The research indicates that those gaps contribute to underreporting of accurate data on the use of pesticide-coated (often with neonicotinoid pesticides) seeds — because farmers may not know what pesticides are on the seeds they plant. Pennsylvania State University reports on the study, in Phys.org, saying, “This lack of data may complicate efforts to evaluate the value of different pest management strategies, while also protecting human health and the environment.” Beyond Pesticides advocates for widespread adoption of organic, regenerative systems and practices that precludes the use of such pesticides.  The research was conducted by a team of scientist from around the U.S., led by Claudia Hitaj, PhD, of the Luxembourg Institute of Science and Technology, and former economist at USDA’s Economic Research Service. In the Phys.org coverage of the study, assistant professor of epidemiology and crop pathology at Penn State, Paul Esker, PhD, notes that this lack of farmer knowledge can lead to overuse of pesticides, which would increase the already considerable risks […]

Safer Practices and Disinfectants for Coronavirus Identified by CDC, As EPA Advances Toxic Products, Suspends Public Health and Environmental Protections

Friday, March 27th, 2020

(Beyond Pesticides, March 27, 2020) Faced with the COVID-19 (coronavirus) threat, there is tremendous pressure to use toxic disinfectants, despite the availability of safer products. In fact, while the Centers for Disease Control and Prevention (CDC) is recommending 70% alcohol for surface disinfection, the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs is advising the use of unnecessarily toxic substances, and reducing standards that govern their allowance on the market. EPA’s pesticide program allowed 70 new disinfectants yesterday, at the same time that the agency overall announced that it is waiving enforcement of environmental standards during the coronavirus outbreak—a devastating blow to public health and environmental protection. Beyond Pesticides, in its factsheet, Protecting Yourself from COVID-19 (coronavirus) without Toxic Sanitizers and Disinfectants, says, “Fight the coronavirus with common sense prevention and safer disinfection products. Avoid products that increase vulnerability to respiratory problems.” (See the factsheet below.) To some extent, the expanded allowance of disinfection products on top of the 281 disinfectants previously permitted has been made possible by relaxing oversight on so-called “inert” or other ingredients that are not disclosed on product labels and often highly toxic. The agency says it is allowing the use of these “inerts” with “no […]

Trump Administration’s Fish and Wildlife Service Proposes Planting of Genetically Engineered Crops in Southeast National Wildlife Refuges

Wednesday, March 25th, 2020

(Beyond Pesticides, March 25, 2020) The Trump administration’s U.S. Fish and Wildlife Service (USFWS) is moving forward with a proposal to grow genetically engineered crops (GECs) on national wildlife refuges in the Southeast United States. The draft environmental assessment allows wildlife to consume pesticide-laden produce, considers chemical-intensive genetically engineered crops no less damaging to the environment than “non-use of GECs,” and permits and escalation of climate change with toxic pesticide use increases. USFW’s proposal fails to mention the success of organic agriculture and consider it as one of the alternative management strategies. The proposal is up for public comment until April 10, 2020. In 2014, public pressure and lawsuits by environmental groups led to the Obama administration’s decision to phase out GE crops and ban neonicotinoid insecticide use on national wildlife refuges. On August 2, 2018, the Trump administration’s USFWS issued a memorandum that reversed the prohibition. The reversal allows the refuge system to make decisions on the use of GECs and neonics on a case-by-case basis in compliance with the National Environmental Policy Act (NEPA), which is also under attack by the Trump administration. The Center for Biological Diversity, Center for Food Safety, and others quickly challenged the 2018 […]

As COVID-19 Disrupts Maui Community, Organizers Take Action for Local Agriculture

Thursday, March 19th, 2020

(Beyond Pesticides, March 19, 2020) As communities across the U.S. brace for an unimaginable health crisis and difficult economic times in the wake of COVID-19, the Beyond Pesticides Hawai’i team has linked arms with Maui’s small farms and community organizations to make sure local farms have the support they need to feed communities and stay in business. The virus is causing shutdowns of everything from farmers markets to restaurants, but community organizers in Maui are making an effort to transform COVID-19 related challenges into a spring board for long-term increase in locally produced, organic food—a sorely needed commodity in Hawai’i.  Hawai’i is the most isolated island chain on the planet. Its fertile soil and climatic conditions coalesce to make Hawai’i potentially a major producer of nutritious food for its residents and for export. However, a complicated plantation history and off-island investment influence has skewed the economy toward tourism and development. The current stark reality is that 85-90% of Hawai’i’s food is imported, making the islands particularly vulnerable to disasters and global events that might disrupt the economy or infrastructure.  COVID-19 is now disrupting the economy and local infrastructure of Maui. Farmers markets and other public gatherings have closed. Tourism is […]

Longest Field Trials Show Organic Practices Yield Higher Returns than Chemical-Intensive Agriculture

Monday, February 24th, 2020

(Beyond Pesticides, February 24, 2019) With more than 90% of total pesticide use deployed in agriculture, organic farming is the keystone solution to the myriad health, environmental, and biodiversity harms of pesticides. A transition to organic and regenerative farming practices — across which there is great overlap — is critical and a tall order, given the entrenched, chemically intensive practices that currently dominate in the U.S. and much of the world. A long-standing research effort by the storied Rodale Institute — the Farming Systems Trial, which began in 1981— is demonstrating that organic agriculture is not only a nontoxic solution, but also, an economically viable one that is critical to a sustainable future. Through the Farming Systems Trial (FST), the Rodale Institute has collected data on crop yields, soil health, energy efficiency, nutrient density of drops, and water use and contamination in organic and conventional systems managed with different levels of tillage. Among the findings of the nearly 40-year research project are these: after a five-year transition period, organic yields are competitive with conventional yields• in drought years, organic yields are as much as 40% higher than conventional yields farm profits are 3–6 times higher for products from organically managed systems […]

EPA Set to Reapprove Cancer-Causing Glyphosate and Bee-Toxic Neonicotinoids

Tuesday, February 4th, 2020

(Beyond Pesticides, February 4, 2020) It was a good day for Bayer/Monsanto. The chemical company’s weed killer glyphosate and its neonicotinoid insecticides are set for reapproval by the U.S. Environmental Protection Agency (EPA), according to interim decisions published last week. EPA reapproval of human carcinogens and chemicals contributing to the pollinator crisis is disappointing for health and environmental advocates, but not surprising to those watchdogging the agency during the current administration. “This is how a captured agency behaves,” said Beyond Pesticides community resource and policy director Drew Toher. “When EPA’s decision making repeatedly reflects the exact wishes of the chemical industry, public trust erodes, and we must look to new policy mechanisms that support the protection of health and the environment.”   On Glyphosate EPA’s glyphosate decision document glosses over the hazards of the chemical and is requiring very few new safety measures when using the herbicide. These measures are focused on agriculture, including minor label changes around drift, guidelines on resistance management, and a label advisory indicating the chemical is toxic to plants and may adversely impact pollinator foraging. The restrictions fail to match those proposed by Health Canada in 2015, which included buffer zones and restricted entry intervals. […]

Croplands’ Toxicity to Pollinators Has Skyrocketed Since the Turn of the Century

Thursday, January 30th, 2020

(Beyond Pesticides, January 28, 2020) The practice of coating seeds with insecticides, now widely adopted as a result of the agrichemical industry, has created increasingly toxic conditions for pollinators foraging on US cropland, finds a study published in Scientific Reports by Penn State University scientists. The data finds that even as overall volume of insecticide use has decreased, the total “bee toxic load” – a term branded by researchers – has increased markedly due in large part to the use of hazardous seed coatings. The switch from one toxic chemical to another is indicative of a chemically-driven agricultural system that, in order to reverse insect, pollinator and bird declines, must undergo rapid changes over the next several decades. Researchers used information from multiple US databases to determine regional patterns in pesticide use and corresponding toxicity loads to pollinators. Thus the term “bee toxic load” was determined by combining the area of land where insecticides were applied with the total toxicity of the particular insecticide used. To compare the impact of changes in the mode of action of the insecticides used, toxicity data was separated between oral and contact toxicity.    Findings indicate that from 1997-2012, contact bee toxic load remained […]

University of California Makes Changes to Reduce Use of Toxic Pesticides, Fails to Embrace Organic

Thursday, January 23rd, 2020

Photo: Beyond Pesticides’ board member Chip Osborne and student advocate Bridget Gustafson meet on a University of California organic land management pilot site, supported by Beyond Pesticides. (Beyond Pesticides, January 23, 2020) University of California (UC) President Janet Napolitano recently has approved recommendations made by the UC Herbicide Task Force, a proposal that falls short of systems change that student activists are advocating. New changes will, however, restrict the use of some toxic pesticides and increase transparency across the university’s ten campuses. While the decision represents an important step forward, advocates remain critical of integrated pest management (IPM) policy and support an overall transition to organic land management. The UC Board of Regents will meet today to discuss the decision. President Napolitano will continue the suspension of glyphosate, established last year, until a UC-wide integrated pest management (IPM) policy is implemented and all ten UC campus locations complete individual IPM plans. A system-wide “oversight committee” will guide and authorize school IPM committees. The overarching IPM policy will restrict application of highly toxic pesticides, only permitting use after a local IPM committee has reviewed and approved its specific use application following an IPM-based assessment. Other synthetic pesticides will be subject to […]

Study Finds EU Moratorium of Persistent Bee-Toxic Pesticides Cannot Eliminate Short-Term Hazards

Thursday, December 5th, 2019

(Beyond Pesticides, December 5, 2019) Five years after three neonicotinoids were banned for use on bee-attractive crops in the EU, researchers found that these bee-toxic chemicals are contaminating soils and poisoning the nectar of oilseed rape (canola). The results of this research point to an immediate need to end the use of persistent environmental contaminants and promote organic practices. Researchers set out to determine whether the EU moratorium eliminated the risk for bees that forage on oilseed rape nectar. They tested for imidacloprid, thiamethoxam, and clothianidin residues in the nectar of winter-sown oilseed rape in from 291 oilseed rape fields in western France for five years following the EU moratorium (2014-2018). Results show all three neonicotinoids were present at least once in the study’s time period. Imidacloprid was detected every year with “no clear declining trend,” though its prevalence fluctuated widely between years. Two samples from 2016 show residues that are five times the expected maximum concentration in nectar of a plant directly treated with imidacloprid. Residue levels in the nectar depend on soil type and increase with rainfall. The researchers put forth in their discussion that the imidacloprid contamination may likely be caused by runoff from neighboring, treated plants. […]

EPA Directive to End Animal Testing of Pesticides Welcomed and Challenged as Not Addressing Inadequate Reviews of Adverse Effects

Friday, October 18th, 2019

(Beyond Pesticides, October 18, 2019) The U.S. Environmental Protection Agency (EPA) issued a directive in September, under Administrator Andrew Wheeler, that changes its pesticide approval process and aims to reduce (mammalian) animal testing significantly by 2035. The agency also announced awards totaling $4.25 million to four universities for development of alternative methods to evaluate chemicals, including pesticides. The move will likely be seen both as an advancement of animal rights, and as a setback for the kinds of testing that can have important implications for human health. Resolution of this issue could be found in a shift away from chemical agriculture and to organic and regenerative practices, which eschew toxic chemicals and synthetic fertilizers, and obviate need for them. The directive affects not only the agency’s own research, but also, as the memo says, EPA will “come as close as possible to excluding from its approval process any reliance on mammal studies conducted after January 1, 2035, including those performed by third parties.” The schools receiving EPA funds to work on alternative testing are Johns Hopkins University, Vanderbilt University and Vanderbilt’s Medical Center, Oregon State University, and the University of California-Riverside.

Settlement Reached to Protect Habitat of Endangered Bumblebee

Thursday, September 26th, 2019

(Beyond Pesticides, September 27, 2019) The U.S. Fish and Wildlife Service (USFWS) will be required to protect the habitat of the endangered rusty patched bumblebee, per a settlement with the Natural Resources Defense Council (NRDC) reached earlier this week. The bee was listed under the Endangered Species Act (ESA) in 2017, but USFWS has yet to designate the “critical habitat” for the bee where improved protections must be made to ensure its recovery. With the decline of both wild and managed pollinators throughout the U.S., action on this issue by federal agencies is sorely needed. According to NRDC, the settlement will require FWS to propose critical habitat by July 31, 2020, unless it makes a finding that habitat protections are not prudent. The Service must then finalize any habitat protections by July 31, 2021. Under ESA, FWS is required to designate the critical habitat of a listed species within one year of its listing if not included within its listing announcement. Thus, by drawing out this process, FWS is flouting this important action that will lead to real on-the-ground protections. “The U.S. Fish and Wildlife Service has violated federal law—again—by not designating critical habitat for the rusty patched bumble bee,” […]

Toxic Pesticides Found, Again, to Yield No Increase in Productivity or Economic Benefit for Farmers

Friday, September 20th, 2019

(Beyond Pesticides, September 20, 2019) The actual utility of pesticides to achieve their purported goals is an under-recognized failing of the regulatory review of pesticide compounds for use. A study published in Scientific Reports now exposes the faulty assumptions underlying the use of neonicotinoids — the most widely used category of insecticides worldwide. The study demonstrates that use of neonicotinoids (neonics) to treat seeds — a very common use of these pesticides — actually provides negligible benefits to soybean farmers in terms of yield and overall economic benefit. The U.S. Environmental Protection Agency (EPA) should take notice, and consider that efficacy ought to have a role in the agency’s evaluation of pesticides for registration. Neonicotinoids are systemic pesticides that move through a plant’s vascular system and are expressed in pollen, nectar, and guttation droplets (drops of sap exuded on the tips or edges of leaves of some vascular plants). They can also persist in the environment — in soil and water — for extended periods. Neonics are applied to seed, as well as to crop soils and to plant foliage. Corn and soybean seed treatments represent the largest uses of neonics in the U.S.: for somewhere between 34% and 50+% […]

Beekeepers Take EPA to Court Over the Bee Toxic Insecticide-Sulfoxaflor—Again

Thursday, September 19th, 2019

(Beyond Pesticides, September 19, 2019) A coalition of beekeepers is suing the U.S. Environmental Protection Agency (EPA) for its recent new use registrations of the neonicotinoid-related insecticide sulfoxaflor on bee-attractive crops . The environmental nonprofit Earthjustice is representing the Pollinator Stewardship Council, the American Beekeeper Federation, and Jeff Anderson—a beekeeper. This is the second suit of its kind to be filed against the agency in the past month: The Center for Biological Diversity and Center for Food Safety have also filed a lawsuit in the 9th Circuit Court of Appeals on the use of sulfoxaflor on over 200 million acres of crops that draw in pollinators to forage on poisoned nectar, pollen, and guttation droplets. Sulfoxaflor is a systemic insecticide whose mode of action is the same as neonicotinoid pesticides. After application, the chemical is absorbed and distributed throughout the plant, including pollen and nectar. These insecticides are selective agonists of insects’ nicotinic acetylcholine receptors—they bind to the receptor and cause it to activate. The impact on foraging bees is generally sublethal, but devastating on a population level. At the request of industry, EPA waived the legal requirement for a full-field study of sulfoxaflor’s impacts on pollinators, erroneously stating that further research would […]

Veteran Policy Experts Form Organic Industry Watchdog Agency

Thursday, September 5th, 2019

(Beyond Pesticides, September 5, 2019) USDA Failures Necessitate Independent Corporate and Governmental Oversight WASHINGTON, DC, Beyond Pesticides, a Washington, DC-based public interest organization founded in 1981 to advocate for healthy air, water, land, and food by eliminating the use of toxic pesticides and advancing organic practices, has announced the formation of its new investigative arm, OrganicEye. The watchdog agency will focus on defending the time-honored philosophy and legal definition of organic farming and food production. “Trusted certified organic production must continue to offer a healthier marketplace alternative and critical environmental protection,” stated Jay Feldman, Executive Director of Beyond Pesticides and former National Organic Standards Board member. As organic agriculture and food marketing has grown into an over $50 billion industry, corporate agribusiness has influenced USDA to shift primary organic production from family-scale farms to large livestock factories, and allow massive hydroponic/soilless greenhouses and fraudulent imports – all devastating to ethical farmers, businesses, and consumers. “We are happy to announce the hiring of Mark Kastel to serve as the Director of OrganicEye,” Mr. Feldman said. Mr. Kastel, one of the founders of The Cornucopia Institute, a venerable organic farm-policy research group, brings over 30 years of diverse involvement in the organic […]

EPA Sued for Registering Known Bee-Killing Pesticide for Use on Bee-Attractive Crops

Tuesday, August 27th, 2019

(Beyond Pesticides, August 27, 2019) The U.S. Environmental Protection Agency (EPA) is the subject to a new legal challenge from environmental groups after approving the use an insecticide shown to be highly toxic to bees and other pollinators.  The lawsuit, filed in the 9th Circuit Court of Appeals by the Center for Biological Diversity and Center for Food Safety, aims to stop the use of sulfoxaflor on more than 200 million acres of crops. As EPA under the Trump administration has become increasingly emboldened to fight for industry priorities, concerned organizations and people are responding by supporting legal challenges and working to pass policies that truly protect wildlife and the environment. According to EPA’s ecological risk assessment for sulfoxaflor, the chemical is “very highly toxic” to bees. A study published last year in the journal Nature found significant concerns with the chemical’s ability to harm already declining pollinator populations. “There is an urgent need to pre-emptively evaluate the potential sub-lethal effects of sulfoximine-based pesticides on pollinators, because such effects are rarely detected by standard ecotoxicological assessments, but can have major impacts at larger ecological scales,” the authors wrote. EPA had already run in to legal problems associated with its registration […]

Children’s IQ Negatively Impacted by Maternal Fluoride Exposure, According to Study

Wednesday, August 21st, 2019

(Beyond Pesticides, August 21, 2019) A birth cohort study in Canada found elevated levels of fluoride exposure during pregnancy are associated with lower IQ scores in 3 to 4-year-old children. This new research, published in the journal JAMA Pediatrics, builds on previous analyses that suggest high fluoride exposure is related to adverse effects to children’s neurodevelopment. Researchers recommend that pregnant mothers should reduce fluoride intake during pregnancy. Noting the controversy of the study, JAMA Pediatrics editor Dr. Dimitri Christakis said it was subjected to “additional scrutiny for its methods and the presentation of its findings.” The Maternal-Infant Research on Environmental Chemicals (MIREC) program recruited pregnant mothers to participate in the study from 2008-2011. A total of 601 mother-child pairs from 6 major cities participated; 41% of them lived in cities with fluoridated municipal water. Exposure was measured through urine samples as well as self-reported maternal daily intake. Children were between ages 3 and 4 when tested for IQ. A 1mg/L increase in maternal urinary fluoride is associated with a 3.7-point decrease in IQ. These findings echo a previous study in Mexico that found a 6-point lower IQ score in school-age children associated with a 1mg/L in maternal urinary fluoride. Women who […]

Chemical-Intensive Agriculture Is Increasingly Toxic to Insects

Thursday, August 15th, 2019

(Beyond Pesticides, August 15, 2019) An article in the journal Plos One, “An assessment of acute insecticide toxicity loading (AITL) of chemical pesticides used on agricultural land in the United States,” shows that recent shifts in insecticide use—from organophosphates and carbamates to synthetic pyrethroids and neonicotinoids—have made a large contribution to the ongoing insect apocalypse. This shift to insecticides that target insects based on both selective toxicity and delivery method occurs within a context of shrinking habitat and biodiversity. The study, by Michael DiBartolomeis, PhD, Susan Kegley, PhD, Pierre Mineau, PhD, Rosemarie Radford, and Kendra Klein, PhD, presents a measure of acute insecticide toxicity loading that incorporates acute toxicity, quantity used, and the rate at which the insecticide degrades. Goulson et al. applied a similar measure in Great Britain that did not incorporate the rate of degradation. Both studies use the median lethal dose (LD50) to honey bees as a measure of acute toxicity and calculate the potential number of bee deaths based on the number of lethal doses of various insecticides applied in the field. In both cases, researchers used toxicity estimates for honey bees because they are widely available. Other insects may be more or less sensitive. The […]

Trump Administration Dealt Multiple Blows to Honey Bees this Month

Tuesday, July 30th, 2019

(Beyond Pesticides, July 30, 2019) Earlier this month, the U.S. Environmental Protection Agency announced a decision to register new uses for the bee-toxic pesticide sulfoxaflor. The decision closely followed a USDA announcement halting the Honey Bee Colonies Survey, combining blows to already suffering beekeepers. According to the nonprofit Bee Informed, this past winter tallied the most colonies lost in a decade—an estimated 37% between October 1, 2018 and April 1, 2019. “Proposing to register sulfoxaflor for use on bee-attractive crops, in the midst of an ongoing pollinator crisis, is the height of irresponsibility,” said Drew Toher, community resource and policy director for Beyond Pesticides in an interview for Bloomberg Environment. “When all of the available data points to significant risks to pollinators from use of this chemical we must face the facts: EPA is working towards the protection of pesticide industry, not the environment,” he said. Sulfoxaflor is a systemic insecticide whose mode of action is the same as neonicotinoid pesticides. After application, the chemical is absorbed and distributed throughout the plant, including pollen and nectar. These insecticides are selective agonists of insects’ nicotinic acetylcholine receptors—they bind to the receptor and cause it to activate. The impact on foraging bees […]

Same Pesticides that Are Killing Bees Killed Off Dozens of Goldfinches in Modesto, CA, Study Finds

(Beyond Pesticides, July 17, 2019) A March 2017 bird kill incident in Modesto, CA can be traced directly back to an insecticide “soil drench” applied to the base of several elm trees by pesticide applicators hired by the city, as detailed in a study published last month in the Journal of Environmental Toxicology and Chemistry. The chemical in question, the neonicotinoid imidacloprid, is implicated in the ongoing pollinator crisis and insect apocalypse, but can also affect bird populations. Prior research estimated that a single seed coated with the insecticide is enough to kill a songbird; this study confirms that such a scenario can and does play out in the real world. Progress and improvement will only occur when pest management practices stop focusing on pesticide use to solve routine pest problems and emphasize prevention. As part of city-wide pest management activities, Modesto officials said that imidacloprid was applied to elm trees in several front yards in a local neighborhood. The application took the form of a “soil drench,” which is when pesticide products are applied to the soil around the base of a tree or shrub. The systemic property of imidacloprid and other systemic insecticides means that the chemical will […]

Study Finds Synergism between Neonicotinoids and Parasites Leads to 70% Declines in Honey Bee Survival

Tuesday, June 25th, 2019

(Beyond Pesticides, June 24, 2019) A study finds that the interaction of a common honey bee parasite with neonicotinoid insecticides causes 70% reductions in overwintering honey bee survival. These results help to explain the unsustainable honey bee colony losses observed in recent decades. Neonicotinoids (neonics) are a class of insecticides that share a common mode of action that affect the central nervous system of insects. Studies show that neonicotinic residues accumulate in pollen and nectar of treated plants, and, given their widespread use and known toxic effects, there is major concern that neonics play a major contributing role in pollinator declines. In the early 2000s, Colony Collapse Disorder (CCD) brought national attention to increased honey bee colony losses. During the same period that CCD and colony losses spiked, neonic prevalence skyrocketed, in large part due to the introduction of seed-delivered technologies. As of 2011, 34-44% of soybeans and 79-100% of maize hectares were preemptively treated with neonics. While CCD prevalence has decreased, colony loss rates (and systemic insecticide use) remain high. A 2018 national survey indicates that U.S. beekeepers currently experience an average annual colony mortality rate of 30.7%, double the pre-CCD baseline of 15% losses. In the present study, […]
