(Beyond Pesticides, January 18, 2018) Research published in early January 2018 has shown that — despite a partial ban on neonicotinoid insecticides instituted in 2014 — 25% of British honey is still contaminated with residue of these “potent, bee-killing” pesticides. The partial ban, which extended to flowering crops, such as oilseed rape (from which canola oil is made), was instituted by the European Union (EU) in response to evidence of serious threats to bee populations. Samples for this study came from beekeepers and were each from a single location. After the partial ban went into effect, scientists had seen some reduction in the contamination rate of neonicotinoids in honey, from greater than 50% prior to the ban. This study demonstrates that these powerful pesticides nevertheless remain common in agricultural areas, posing serious threats to bees (and other pollinators). This discovery is likely to accelerate pressure on the EU to ban all outdoor use of neonicotinoids, with a vote coming perhaps as soon as in the next few months. “While the frequency of neonicotinoid contaminated samples fell once the EU ban was in place, our data suggest that these pesticides remain prevalent in the farming environment,” said Ben Woodcock, of the UK’s […]

(Beyond Pesticides, January 17, 2018) The organophosphate insecticides chlorpyrifos, malathion, and diazinon are likely to jeopardize the continued existence of endangered species and adversely modify their critical habitats, according to the newly released report from the National Marine Fisheries Service (NMFS). The insecticide cholorpyrifos, whose ban was rescinded by the Trump Administration last year, despite overwhelming evidence of neurological and brain damage to children, is once again being shown to be too toxic for continued use. Under Section 7 of the Endangered Species Act (ESA), any agency action requires a finding that it “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” The December 31, 2017 Biological Opinion from NMFS followed an ecological assessment that relied upon multiple lines of evidence to determine effects to species and their designated habitats. These include “the direct and indirect toxicity of each chemical to aquatic taxa groups (e.g. fish, mammals, invertebrates); specific chemical characteristics of each pesticide (e.g. degradation rates, bioaccumulation rates, sorption affinities, etc.); expected environmental concentrations calculated for generic aquatic habitats; authorized pesticide product labels; maps showing the spatial overlap of listed species’ habitats with pesticide use areas; […]

(Beyond Pesticides, January 16, 2018) In spite of findings that neonicotinoid (neonic) insecticides pose both acute and chronic risks to pollinators, aquatic life, and birds, the U.S. Environmental Protection Agency (EPA) is seeking comment that could support their continued use. Comments are due by February 20, 2018.  Tell EPA that neonics pose unacceptable risks to pollinators, aquatic life, and birds! And, ask your Congressional delegation push EPA to do the right thing. Last month, EPA released preliminary ecological (non-pollinator) assessments for the neonicotinoids clothianidin, thiamethoxam, dinotefuran, and the terrestrial ecological assessment for imidacloprid, finding that these pesticides pose both acute and chronic risks to aquatic life and birds. Treated seeds are identified as posing the highest dietary risks to birds, confirming previous research that neonics are highly hazardous not only to bees, but also, to birds, aquatic life, and other non-target organisms. However, EPA’s assessments also cover spray treatments. EPA opened the public comment period for these assessments on December 15, 2017. Along with outlining the risks identified in the assessments, the agency is especially requesting feedback on the benefits of continued use of the neonics on cotton and citrus crops, identified in last year’s pollinator assessments as posing risks to honey bees. […]

(Beyond Pesticides, January 12, 2018) Honey bees display a concerning attraction to the herbicide glyphosate and the fungicide chlorothalonil at certain concentrations, new research from scientists at the University of Illinois (UIL) reveals. Results are reminiscent of a 2015 study published in the journal Nature, which found that honey bees display a preference for foods treated with neonicotinoids, a class of insecticides implicated in global pollinator declines. Since the crisis became public knowledge in 2006, managed honey bees have experienced unsustainable levels of colony loss, and one in four species of native bees in North America and Hawaii are at risk of extinction. This new research adds to growing concerns that, while neonicotinoids continue to play a primary role in the pollinator crisis, their elimination would still leave a myriad of other toxic chemical threats to the recovery of these critical species, upon which so much of our food supply relies. UIL scientists investigated honey bees’ preference for a range of pesticides as well as a number of naturally occurring chemicals that honey bees would likely encounter in the field. In the experiment, pollinators were put in a large enclosure and allowed to fly to different feeders stocked with either […]

(Beyond Pesticides, January 8, 2018)  With a long-documented history of children’s exposure to pesticides that drift from agricultural fields to school yards, California’s new regulations establishing no-spray buffers took effort January 1, as labor and public health groups acknowledged the progress and inadequacy of the measure. The new rule, DPR 16-004 Pesticide Use Near Schoolsites, adopted by the California Department of Pesticide Regulation (DPR), prohibits many pesticide applications within a quarter mile of public K-12 schools and licensed child day-care facilities during school hours, Monday through Friday between 6 a.m. and 6 p.m. This includes all applications by aircraft, sprinklers, air-blast sprayers, and all fumigant applications. In addition, most dust and powder pesticide applications, such as sulfur, will also be prohibited during this time. The new rule was announced in November, 2017. Advocates say the new rules fail to address persistent low-level exposures associated with the use of the pesticides near schools, which are in agricultural areas that are disproportionately Latino and from farmworker families. There is continuing concern about children’s exposure to hazardous pesticides because children use school grounds after school hours and on weekends and residues from drift may remain on school grounds. Many pesticides used are persistent and systemic, lingering […]

(Beyond Pesticides, January 4, 2018) Last month, the U.S. Environmental Protection Agency (EPA) released the preliminary ecological (non-pollinator) assessments for the neonicotinoids (neonics); clothianidin, thiamethoxam, dinotefuran, and the terrestrial ecological assessment for imidacloprid, finding that these pesticides pose both acute and chronic risks to aquatic life and birds. Treated seeds are identified as posing the highest dietary risks to birds, confirming previous research that neonics are highly hazardous not only to bees, but to birds, aquatic life, and other non-target organisms. Released December 15, 2017, EPA opened the public comment period for these assessments until February 20, 2018. Along with the risks identified in the assessments, the agency is specially requesting feedback on the benefits of continued use of the neonics in cotton and citrus crops identified in last year’s pollinator assessments as posing risks to honey bees. EPA states, “We believe early input from the public will be helpful in developing possible mitigation options that may be needed to address risks to bees.” This despite evidence of long-term systemic exposures to non-target organisms that support a phase-out of these pesticides. EPA believes that neonicotinoids are crucial for the management of Asian citrus psyllid, an invasive pest that causes citrus greening, […]

(Beyond Pesticides, December 21, 2017) On December 18, the U.S. Environmental Protection Agency (EPA) declared that glyphosate is likely not carcinogenic. Relatedly, after weeks of stalemate on a decision by European countries, the European Union (EU) voted, in late November, to extend the license for the herbicide for another five years, despite massive opposition in member countries. In the U.S., the Center for Biological Diversity charged that the EPA assessment relied heavily on industry studies to arrive it its conclusion, and ignored its own guidelines for assessing cancer risks. Senior scientist at the Center for Biological Diversity Nathan Donley said, “The only way the EPA could conclude that glyphosate poses no significant risks to human health was to analyze industry studies and ignore its own guidelines when estimating cancer risk. . . . The EPA’s biased assessment falls short of the most basic standards of independent research and fails to give Americans an accurate picture of the risks posed by glyphosate use.” Glyphosate is due for its EPA registration review in 2019, and opponents are concerned that the December 18 announcement portends likely re-registration — which advocates say is bad news for human health and the environment. As the chief […]

(Beyond Pesticides, December 14, 2017) Tests of waterways in the United Kingdom (UK) reveal rivers contaminated with neonicotinoids, the class of chemicals highly toxic to bees and aquatic invertebrates. And now, although neonicotinoids were banned from use on certain crops in the European Union (EU) in 2013, an EU vote to extend the ban has been delayed. The test results raise concerns over neonicotinoids’ impacts on waterways, especially to fish and birds. Under a new EU mandate -Water Framework Directive ‘Watch List’ initiative – the UK was required to monitor for all five commonly used neonicotinoids: imidacloprid, clothianidin, thiamethoxam, acetamiprid and thiacloprid. Twenty-three sites were sampled in 2016, 16 in England, four in Scotland, three in Wales and three in Northern Ireland. This is the first systematic testing of neonicotinoids in rivers in Britain. According to the results, half the rivers tested in England had either chronic or acute levels of contamination. Of the 23 rivers tested across Britain, all but six contain neonicotinoids. Eight rivers in England exceed recommended chronic pollution limits, and two are acutely polluted. Neonicotinoids are not only highly toxic to bees but also highly toxic to aquatic insects, which are a vital food source to […]

(Beyond Pesticides, December 12, 2017) According to a Reuters story, agrichemical company Monsanto plans to offer farmers a cash incentive to use its highly toxic and drift-prone dicamba-based herbicide next season, despite links to widespread crop damage that has pitted neighbor against neighbor in agricultural communities throughout the country. The move comes as more and more states enact or consider restrictions on use of the herbicide, which is intended to be paired with genetically engineered (GE) soybean seeds resistant to both dicamba and another controversial herbicide produced by Monsanto, glyphosate. Monsanto plans to provide farmers more than half of the cost of herbicide per acre as an incentive to plant its GE seeds. However, given the range of new regulations surrounding the products, as well as the social stigma around its use, it remains to be seen whether the offer will sway farmers. Dicamba has stirred up fights between neighbors in a number of agricultural communities. Bader Farms, which grows over 110,00 peach trees on over 1,000 acres in Missouri, is suing Monsanto after its insurance company issued a refusal to pay for damages caused by dicamba drift from surrounding farms. In June of this year, University of Arkansas’ agricultural […]

(Beyond Pesticides, December 4, 2017) You told the Arkansas Plant Board to exercise its authority to protect farmers, consumers, and the environment from use of the herbicide dicamba on genetically engineered (GE) soybeans, and the board listened. Now, we need to ask the board to stop the use of 2,4-D on GE cotton. The action of states is critical as the federal government ignores basic safety concerns. Action in Arkansas will influence other states. Tell the Arkansas Plant Board to adopt the proposed rule and to prohibit use of 2,4-D on cotton! The decision concerning 2,4-D use on herbicide-tolerant cotton goes to the Arkansas Plant Board on December 12. The choice has many similarities to the decision to allow — and then prohibit — the use of dicamba on herbicide-tolerant soybean varieties. Both 2,4-D and dicamba are phenoxy herbicides — 2,4-D being the infamous ingredient (along with 2,4,5-T) of Agent Orange. Our voices were heard when the Arkansas Plant Board considered dicamba, so please weigh in on 2,4-D. At this December 12 meeting, the Arkansas Plant Board is holding a hearing on a proposed regulation that would allow the Board to request more information from pesticide registrants, which could support restrictions based on conditions within Arkansas. The […]

(Beyond Pesticides, November 30, 2017)  A French court suspended the license of two pesticide products citing their toxicity to bees. The products, Closer and Transform, both contain the active ingredient, sulfoxaflor, which is highly toxic to bees. The ruling overturned the decision by France’s health and environment agency, ANSES, to allow the use of the sulfoxaflor products. Sulfoxaflor use was also challenged in the U.S. by beekeepers concerned about its impact on already declining bee populations. Sulfoxaflor is a relatively new active ingredient whose mode of action is similar to that of neonicotinoid pesticides. Even though it has not been classified as a neonicotinoid, it elicits similar neurological responses in honey bees, with many believing that sulfoxaflor is a new generation of neonicotinoid. Its initial 2013  U.S. registration was challenged by beekeepers and subsequently vacated by the Ninth Circuit Court of Appeals due to overwhelming risks to bees and the U.S. Environmental Protection Agency’s (EPA) inadequate review of the data. The court concluded that EPA violated federal law when it approved sulfoxaflor without reliable studies regarding the impact that the insecticide may have on honey bee colonies. By vacating EPA’s unconditional registration of the chemical, sulfoxaflor could not be used […]

(Beyond Pesticides, November 28, 2017) Bumblebees exposed to field-realistic levels of neonicotinoid insecticides have problems with “buzz pollination” that results in reduced pollen collection, according to new research published in Scientific Reports. This is the latest science to tease out the complex ways in which neonicotinoids interfere with these important pollinators, providing yet another reason to eliminate these highly toxic, systemic insecticides from the environment. Flowers that bumblebees pollinate require the insects to emit soundwaves, or ‘sonicate’ to release their pollen, and bumblebees must perfect their techniques over time in order to maximize the pollen they are able to collect. Researchers tested the effect of neonicotinoids on bumblebees’ sonication abilities by exposing them to field realistic doses of the insecticide thiamethoxam at rates of 2 parts per billion (ppb) and 10 ppb, and observing their ability to successfully collect pollen. A control group that never came in contact with thiamethoxam was also used to compare the progress of the exposed group. Lead author of the study, Penelope Whitehorn, PhD, indicated, “We found that control bees, who were not exposed to the pesticide, improved their pollen collection as they gained experience, which we interpreted as an ability to learn to buzz […]

(Beyond Pesticides, November 21, 2017) Both the active and inert ingredients in common herbicides induce antibiotic resistance in human pathogenic bacteria, according to the latest research from New Zealand scientists, published in Microbiology this week.  Previous research from the same team found in 2015 that commercial formulations of Roundup (containing glyphosate and inert ingredients) and Kamba (containing 2,4-D, Dicamba, and inert ingredients) caused antibiotic resistance to develop in Salmonella eterica and Escherichia coli, but this new research drills down into what ingredients in these formulations resulted in the effect. Lead author of the study, Jack Heinemann, PhD, University Canterbury’s School of Biological Sciences, explains that ultimately this research indicates that, “The sub-lethal effects of industrially manufactured chemical products should be considered by regulators when deciding whether the products are safe for their intended use,” Scientists parsed out the effects of individual active and inert ingredients by obtaining pure, technical grade dicamba, 2,4-D, and glyphosate, as well as the inert co-formulants “Tween80” and “CMC,” which are respectively, used to reduce surface tension and regulate the viscosity in a formulated herbicide, though also used as emulsifiers in foods like ice cream and in medicines. The technical grade herbicides were first applied to […]

(Beyond Pesticides, November 14, 2017) The European Commission has again been unable to come to a consensus over renewing approval for Monsanto’s popular herbicide,  glyphosate.  Member states voted last week, but failed to approve, continued use even after months of deliberation over the controversial herbicide. Glyphosate (Roundup) is also up for review in the U.S., but many expect the herbicide to be reregistered by the U.S. Environmental Protection Agency (EPA), despite health concerns. The proposal to renew the European Union (EU) license for glyphosate for another five years failed to a reach a qualified majority, meaning a decision has again been postponed, according to reports. The current license is due to expire on December 15, 2017, but there is an 18-month grace period. Fourteen countries voted in favor of the renewal, nine against, while five, including Germany, abstained from voting. According to reports, a qualified majority requires that 55 percent of EU countries vote in favor and that the proposal is supported by countries representing at least 65 percent of the total EU population. France, which voted against the proposal, said it would only support a renewal for three-year phase-out. The proposal could now be referred to an appeals committee, or alternatively, the Commission could draw […]

(Beyond Pesticides, November 9, 2017) Vietnam veterans suffering from certain Agent Orange-related health conditions will continue to wait for compensation. U.S. Department of Veteran Affairs (VA) Secretary David Shulkin announced last week he intends to delay a decision to expand coverage to new illnesses. Despite a robust review by the National Academy of Medicine, which recommended expanding disability compensation for bladder cancer, hyopothyroidism, high blood pressure, and Parkinson’s-like tremors due to past exposure to the toxic herbicide cocktail, the VA decided to take no action. “After thoroughly reviewing the National Academy of Medicine (NAM)’s latest report regarding Veterans and Agent Orange, and associated data and recommendations from the NAM Task Force, I have made a decision to further explore new presumptive conditions for service connection that may ultimately qualify for disability compensation,”  Secretary Shulkin said in a press release last week.  “I appreciate NAM’s work and the commitment and expertise of VA’s NAM Task Force, and look forward to working with the Administration on the next steps in the process.” Given a promise from VA Secretary Shulkin to provide a decision on the new ailments by November 1st, Veterans groups are crying foul, and placing blame on the Trump administration, […]

(Beyond Pesticides, October 30, 2017) Tell the Arkansas State Plant Board to stand up to Monsanto, and protect farmers by banning dicamba’s use in Arkansas agriculture. Comment period closes today, Monday, October 30, 2017, at 4:30pm (Eastern Time). Your comments are needed to stop the disaster in Arkansas being created by Monsanto’s new genetically engineered (GE) cropping system, which relies on the toxic pesticide dicamba. If Arkansas bans dicamba, other states should and will follow —given the chemical industry’s takeover of the U.S. Environmental Protection Agency (EPA), which is allowing this extremely hazardous pesticide use. This is a problem that has regional and national implications, given the breakdown of the EPA and its pesticide program. We cannot let this failure of protection stand in Arkansas or anywhere in the country. Promoted by Monsanto as a way to address rampant Roundup (glyphosate) resistance, Monsanto’s new GE soybeans are now able to withstand both glyphosate and dicamba, an older herbicide with a range of documented health effects —from neurotoxicity to reproductive problems. Dicamba is also highly volatile and, as a result, has drifted across crop fields throughout the region, damaging high value fruit tree and organic operations. The Arkansas State Plant Board is […]

(Beyond Pesticides, October 20, 2017) Last week, the U.S. Environmental Protection Agency (EPA) announced that label changes to the herbicide dicamba would be made to try to minimize drift that has left thousands of acres of crops already damaged this season. The label changes include making dicamba “restricted use,” which allows only certified applicators to apply the chemical. Dicamba drift has been damaging farmers’ crops for at least two years due to the approval of new dicamba-tolerant genetically engineered (GE) crops. Advocates says that the new changes do not ensure that drift will be eliminated. According to EPA, the agency reached an agreement with the makers of dicamba, (Monsanto, BASF and DuPont) to restrict its application. This comes after hundreds of official complaints of crop damage related to dicamba across 17 states this year alone, leading to questions about the new formulation of the chemical used in genetically engineered (GE) crop productioon. New GE crops developed by Monsanto must be paired with specific formulations of dicamba, and thus led to a vast increase in dicamba use over the past couple growing seasons. Dicamba-based herbicide use has climbed dramatically as farmers have adopted, especially, Monsanto’s GE soybean seeds; in the 2017 season, 20 […]

(Beyond Pesticides, October 18, 2017) Effective immediately, the European Parliament has banned Monsanto lobbyists, excluding the chemical company from access to committee meetings and digital resources, as well as no longer permitting Monsanto lobbyists to meet with any Member of the European Parliament (MEP). This limit to its influence is a serious blow to Monsanto’s advocacy campaign to promote the safety of its weedkiller glyphosate, (Roundup). The decision to ban came amid mounting public pressure to deny European Union re-licensing of glyphosate, one of the world’s most widely used herbicides. (See glyphosate listing in Beyond Pesticides’ Pesticides Gateway, the active ingredient in Monsanto’s Roundup herbicide.) Glyphosate is classified as “probably carcinogenic to humans” by the World Health Organization’s International Agency for Research on Cancer (IARC). Monsanto, the world’s largest GE-seed and seventh-largest pesticide company, is eager to suppress IARC’s ranking. In fact, before being banned, the European Parliament had questioned Monsanto’s funding of counter-studies in order to discredit independent scientists working to limit the public’s exposure to toxic chemicals. In a related development, independent scientists sent a letter to the scientific journal Critical Reviews in Toxicology, calling for the retraction of a 2016 paper that refuted glyphosate’s cancer risks after it was learned that […]

(Beyond Pesticides, October 17, 2017) In a letter to the scientific journal Critical Reviews in Toxicology, scientists called for the retraction of a 2016 paper that refuted glyphosate’s cancer risks after it was learned that the paper was secretly edited and funded by Monsanto, manufacturer of glyphosate. The paper in question, “An Independent Review of the Carcinogenic Potential of Glyphosate,” is a review of the 2015 decision by an expert Working Group of the International Agency for Research on Cancer (IARC) to designate glyphosate, the active ingredient in Monsanto’s flagship product, Roundup, as “probably carcinogenic to humans” (Group 2A). However, a new report this summer discovered conflict of interests not revealed at publication. Contrary to the journal’s conflict-of-interest disclosure statement, Monsanto directly paid at least two of the scientists who authored the paper, and a Monsanto employee substantially edited and reviewed the article prior to publication, in clear contradiction to the disclosure statement. The retraction-request letter highlights a range of failures involved in the published review: Failure to disclose that at least two panelists who authored the review worked as consultants for, and were directly paid by, Monsanto for their work on the paper. Failure to disclose that at least […]

(Beyond Pesticides, October 11, 2017) Last week, the Natural Resources Defense Council (NRDC) filed a lawsuit challenging the U.S. Environmental Protection Agency’s (EPA) registration of neonicotinoid pesticides – acetamiprid, dinotefuran, and imidacloprid, and the agency’s failure to first consult with the U.S. Fish and Wildlife Service on the pesticides’ impact on threatened or endangered species. The lawsuit, filed in the U.S. District Court for the District of Columbia, challenges the failure of the federal government to evaluate the impacts of neonicotinoid pesticides (“neonics”) on threatened and endangered species, like the rusty patched bumble bee, the black-capped vireo, and the San Bruno elfin butterfly. The suit cites widespread presence of neonics in the environment which presents serious risks to wildlife across large portions of the country. It contends that they pose significant adverse consequences to threatened and endangered species. According to the lawsuit, because of toxicity and pervasive environmental contamination, NRDC is now challenging EPA’s registrations of pesticide products containing one of three main neonic active ingredients—acetamiprid, dinotefuran, and imidacloprid—and seeks vacatur of those registrations until EPA complies with the law. “The EPA ignored endangered bees, butterflies, and birds when it approved the widespread use of neonics,” said Rebecca Riley, a senior […]

(Beyond Pesticides, October 2, 2017) Elementary school students at New York City’s PS 290 are taking a stand against toxic pesticide use in New York City parks, supporting Intro 800, a bill introduced by Manhattan Councilmember Ben Kallos. “We’re going to make a great big fuss,” the children in Mrs. Paula Rogivin’s kindergarten class chanted in a skit performed in front of the NYC Committee on Health this week. Since New York City (NYC) passed Local Law 37, Pesticide Use by City Agencies, in 2005 to stop toxic pesticide use on City owned and leased land, it turns out that some pesticides known to be hazardous were not captured by the law. As a result, the proposed legislation is intended to strengthen restrictions to ensure more comprehensive restrictions that limit pesticides to biological pesticides. Local Law 37 restricts the use of acutely toxic and carcinogenic pesticides as defined by the U.S. Environmental Protection Agency (EPA), and developmental toxicants as defined by the state of California under Prop 65. Exemptions allowing the use of these pesticides are granted based on a waiver review process that requires evidence that the chemicals are necessary to protect public health. Otherwise, City agencies are encouraged […]

(Beyond Pesticides, September 18, 2017) Ask California to ban the neurotoxic pesticide chlorpyrifos that’s on the food we eat from California –since the administrator of EPA refused to take the action agency scientists said is necessary to protect children. Tell California to ban chlorpyrifos! In view of EPA’s retraction of its proposal to revoke food residue tolerances of the highly neurotoxic insecticide chlorpyrifos, despite its own assessment that the chemical is too toxic to children, it is especially important that California take action to ban the chemical. California, the home of the largest agriculture industry in the country, used over 1 million pounds of chlorpyrifos on over a million acres in 2012. EPA’s assessment is also support for the classification of chlorpyrifos as a developmental toxicant, an issue being considered on a parallel track by California’s Office of Environmental Health Hazard Assessment (OEHHA), which oversees the “Prop 65” list. EPA’s assessment, which incorporates recommendations from a 2016 Scientific Advisory Panel (SAP), finds that children exposed to high levels of chlorpyrifos have mental development delays, attention problems, attention-deficit/hyperactivity disorder problems, and pervasive developmental disorders. The SAP agreed with EPA that there is an association between chlorpyrifos prenatal exposure and neurodevelopmental outcomes in children. […]
