(Beyond Pesticides, March 12, 2018) European Regulators Confirm Neonicotinoids Harm Bees, Increasing Likelihood of Continent-Wide Ban A comprehensive assessment released last week by the European Food Safety Authority (EFSA) confirmed that neonicotinoids, the most widely used class of insecticides in the world, pose risks to honey bees and wild pollinators. EFSA analyzed over 1,500 studies from academia, beekeeper associations, chemical companies, farmer groups, non-governmental organizations, and national regulators. EFSA’s risk assessment provides a definitive, independent conclusion that overall, continued use of these chemicals risks the long-term health of pollinator populations. Tell Your Governor to Ban Neonicotinoid Insecticides “The availability of such a substantial amount of data as well as the guidance has enabled us to produce very detailed conclusions,” said Jose Tarazona, PhD, head of EFSA’s Pesticides Unit in a press release. This is EFSA’s second comprehensive evaluation of the three most commonly used neonicotinoids: imidacloprid, clothianidin, and thiamethoxam. Earlier research finalized in 2013 led the European Union (EU) to ban use of the three neonicotinoids on agricultural flowering crops. The new assessment applies EFSA guidance to assessing risks to bees and on the initial review. It includes literature not only on honey bees, but also on wild pollinators, including bumblebees […]

(Beyond Pesticides, March 9, 2018) Milk from 100% grass-fed cows has higher levels of beneficial fatty acids than conventional and even organic milk, according to a study published by an international team of scientists in the journal Food Science and Nutrition. The research follows up on data published in 2013, which compared only conventional and organic milk, finding organic milk contained 62 percent more omega-3 fatty acids and 25 percent fewer omega-6s. “Grassmilk farmers have long been telling us that they believed the nutrition of this milk was higher than that of the milk they were producing when they were still feeding grain,” said Logan Peterman, agricultural research and analytics manager at Organic Valley to Wisconsin Public Radio. “We kind of set about to test that question and really make sure that the signal was there, that we could be certain of it, that we were following the correct methods and also that it was sort of refereed by an outside party.” The study compared the composition of several fatty acids within the three types of milk tested (conventional, organic, and grass-fed). Of primary concern was the ratio of omega-6 to omega 3 fatty acids. Although omega-6s are not necessarily […]

(Beyond Pesticides, March 8, 2018) Simple approaches that increase populations of vertebrate predators, like bats and falcons on farms, can reduce pesticide use, increase on-farm productivity, and conserve wildlife, according to a literature review published by researchers at Michigan State University in the journal Agriculture, Ecosystems and Environment.  The review encompasses 48 studies published over the last 150 years on the effect of human interventions to enhance natural ecosystem services. Results point not only to new methods to improve on-farm pest management, but also potential ways to engage farmers and citizen scientists in implementing these win-win strategies. Researchers looked at a number of methods tested in the scientific literature that would increase on-farm populations of vertebrate pest predators. Broadly, discrete approaches such as installing structures like nest boxes, perches, and artificial roosts were investigated alongside more wide-ranging systems aimed at altering habitat and increasing landscape complexity. The latter includes methods such as installing field borders, increasing tree cover, reintroducing native species, and eliminating invasives. The more discrete approaches provided a simpler, more accessible, and less expensive method of pest management when compared to approaches that require more wide-ranging landscape changes, though the benefits of those activities were not negligible. Nest […]

(Beyond Pesticides, March 2, 2018) Neonicotinoids, the most widely used class of insecticides in the world, do pose risks to honey bees and wild pollinators, according to a comprehensive assessment released last week by the European Food Safety Authority (EFSA). Encompassing an analysis of over 1,500 studies from academia, beekeeper associations, chemical companies, farmer groups, non-governmental organizations, and national regulators, EFSA’s risk assessment provides a definitive, independent conclusion that overall, continued use of these chemicals risks the long-term health of pollinator populations. After delaying a vote that would ban all outdoor uses of neonicotinoids in December in anticipation of EFSA’s assessment, the European Commission will revisit the issue as soon as March 22. “The availability of such a substantial amount of data as well as the guidance has enabled us to produce very detailed conclusions,” said Jose Tarazona, PhD, head of EFSA’s Pesticides Unit in a press release. This is EFSA’s second comprehensive evaluation of the three most commonly used neonicotinoids: imidacloprid, clothianidin, and thiamethoxam. Earlier research finalized in 2013 led the European Union (EU) to ban use of the three neonicotinoids on agricultural flowering crops. The new assessment builds upon the initial review, and includes literature not only on […]

(Beyond Pesticides, March 5, 2018) Even if you don’t live in California, chances are that you eat food that is grown there. Unless all that food is organic, some of it was probably sprayed with chlorpyrifos, exposing not only you, but also the farmworkers responsible for its cultivation and harvest. Farmworker families –especially children—who usually live close to the treated fields, suffer higher impacts than those living further away. Tell Governor Brown to ban chlorpyrifos now, for the sake of the children. Five months after the California Department of Pesticide Regulation (DPR) issued its weak and inadequate draft risk assessment for the brain-harming pesticide chlorpyrifos, the state’s Scientific Review Panel (SRP) ordered DPR back to the drawing board to produce a much stronger draft that properly considers the risk of harm to the developing brain. 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 one million pounds of chlorpyrifos on over a million acres […]

(Beyond Pesticides, March 2, 2018) California’s Department of Food and Agriculture (CDFA) can no longer use toxic pesticides in accordance with its Statewide Plant Pest Prevention and Management Program, due to a Superior Court-ordered injunction issued last week. This action came in response to a lawsuit filed by the City of Berkeley and 11 public health, environmental, conservation, citizen and food safety groups, which argued that CDFA has failed in its duty to protect human health, the environment and the state’s organic agriculture. CDFA’s lack of compliance with California’s Environmental Quality Act (CEQA) resulted in the court’s suspension of “all chemical activities undertaken…to control or eradicate pests,” “unless and until” the agency corrects violations. The injunction follows a January 8 court ruling annulling CDFA’s Program Environmental Impact Report (PEIR), due to numerous state environmental law violations. Under CEQA, agencies must produce an Environmental Impact Report (EIR –the California state equivalent of an EIS) for any project with potentially significant environmental impacts. Unlike the National Environmental Policy Act (NEPA), it also requires the state to prevent or mitigate negative impacts. Agencies may avoid conducting an EIR for each action by conducting a programmatic EIR (PEIR) for its program. In its outline of […]

(Beyond Pesticides, March 1, 2018)  A comprehensive review of notorious, bee-killing neonicotinoid insecticides finds that crop yields and on-farm profit can be maintained and improved by replacing these toxic chemicals with alternative pest management strategies. The new study is part of an ongoing update to the 2014 Worldwide Integrated Assessment undertaken by an international team of scientists called the Task Force on Systemic Pesticides. The results of this review point to the need for strong action against these chemicals by all levels of government. “Regulators need to realize that if we want sustainable agricultural practices, we need a more restrictive regulatory framework and programs to support farmers making the switch,” said Task Force co-chair and scientist at France’s National Scientific Research Centre Jean-Marc Bonmatin, PhD, in a press release. “Our findings on the availability of alternatives will be particularly relevant where new restrictions on neonics are being considered.” The Task Force reviewed 200 studies on systemic insecticides, looking at their use and pest resistance in annual and perennial crops, the viability of alternative pest management techniques, and the potential to implement alternative forms of crop insurance to cover risks, rather than spray expensive insecticides. For perennial crops, researchers focus on the […]

(Beyond Pesticides, February 26, 2018) It is no secret that large organic dairy herds of 15,000 to 20,000 cows or more dot the Western US in California, Colorado and Texas in particular. They have repeatedly come under fire from watchdog groups, journalists and farmers who have observed and documented the absence of cows on pasture during grazing season, as required by the Organic Foods Production Act (OFPA). This circumventing of the law could soon change with the commercialization of the fluorescene spectroscopy (FS), which detects the amount of forage a dairy herd is eating by measuring the luminescence of metabolized grass in milk. The law requires that herds graze daily during a given region’s growing season, at least 120 days per year, and consume a minimum of 30% grass in their daily diet. Until now, there has been no technology to scientifically verify that organic milk comes from grass-fed dairy cows. . The organic dairy certification system relies on visual inspections by certifiers during the grazing season and an evaluation of the dairy’s herd management plan.. While most organic dairies are in compliance, there are questions about the ability of the super-large dairies to meet stringent organic pasture regulations. The […]

(Beyond Pesticides, February 26, 2017) U.S. Representatives Earl Blumenauer (D-OR) and Jim McGovern (D-MA) reintroduced the Saving America’s Pollinators Act (H.R. 5015), which suspends the registration of certain neonicotinoid insecticides until the U.S. Environmental Protection Agency conducts a full scientific review that ensures these chemicals do not harm pollinators. Last week, Beyond Pesticides joined Rep. Blumenauer and other experts from environmental, conservation, whistleblower, and farmworker health groups on Capitol Hill to urge Congress to take action to protect pollinators in the face of ongoing obstruction by an increasingly industry-influenced EPA. Tell your Representative to cosponsor the Save America’s Pollinators Act!“ Pollinators are the backbone of America’s agriculture system. Acting now to protect them and stop their decline is essential to the sustainability of our nation’s food supply,” Rep. McGovern said. “Simply taking the word of the manufacturers that their products are safe is not an option. Consumers need strong oversight. That is why I am proud to join Congressman Blumenauer in demanding the EPA fully investigate the effect that certain harmful pesticides may have on the vitality of our pollinators.” Numerous scientific studies implicate neonicotinoid pesticides as key contributors to the global decline of pollinator populations. EPA’s own scientists have found that […]

(Beyond Pesticides, February 23, 2018) Agrichemical corporation Monsanto has lost its bid to halt a statewide ban on the use of its specialty dicamba herbicide in Arkansas. Despite a lengthy process of evaluation and public comment that led to a prohibition on the use of drift-prone dicamba herbicides during the growing season on Arkansas farms, Monsanto made one last-ditch attempt to stop the law from going into effect by suing the entire state. With the industry’s loss, Arkansas is on track to implement the toughest restrictions against dicamba in the U.S. State Circuit Court Judge Chris Piazza dismissed the lawsuit last week based on a recent Arkansas Supreme Court ruling, which held that the state cannot be made a defendant in court. Monsanto’s lawsuit argued against the makeup of the state’s Plant Board, which voted to prohibit the company’s product last November. Monsanto also made claims that the state did not consider the economic damage a ban on the herbicide would cause, despite not seeking monetary restitution in court. Beyond Pesticides led a nationwide campaign to urge action by the Arkansas Plant Board to ban dicamba. Dicamba is an herbicide originally registered for use in 1967 to control broadleaf weeds. […]

(Beyond Pesticides, February 22, 2018) Online retailer Amazon will pay $1.2 million in penalties to settle violations to U.S. regulations for selling illegal and misbranded pesticides in its online store. Under the terms of the settlement, Amazon will monitor and remove illegal pesticide products from its website. These products, mostly imported, were not registered for use and sale in the U.S. and can pose hazards to unsuspecting consumers. As part of an agreement with the U.S. Environmental Protection Agency (EPA) Amazon has agreed to pay $1.2 million in administrative penalties for nearly 4,000 violations of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) by allowing third-party distributors to sell imported pesticide products on Amazon even though the products were not registered in the U.S. While agreeing to the settlement, Amazon neither admitted nor denied the specific facts alleged by the EPA. “This agreement will dramatically reduce the online sale of illegal pesticides, which pose serious threats to public health in communities across America,” EPA Region 10 Administrator Chris Hladick said in a news statement. The most concerning illegal products being sold are insecticide chalk products imported from Chinese manufacturers (3 pcs Cockroaches Bugs Ants Roach Kills chalk; Miraculous Insecticide Chalk; […]

(Beyond Pesticides, February 21, 2018) Officials in Quebec announced this week that the Canadian province will implement new restrictions on the use of five highly toxic pesticides. As part of efforts to fulfill the vision of the Quebec Pesticide Strategy, a progressive, forward-thinking framework for pesticide regulation announced in 2015, atrazine, chlorpyrifos, and the neonicotinoids imidacloprid, clothianidin, and thiamethoxam will have new limits placed on their use. “Together with the groups involved, we have found a balanced regulatory solution to protect the health of our farmers, aquatic ecosystems and pollinators,” Isabelle Melancon, Quebec’s Minister of Sustainable Development, Environment, and the Fight Against Climate Change (Environment Ministry) said in a press release. “We hope to obtain in this way a significant reduction in the use of the most at-risk pesticides in Quebec, in a framework of transparency and integrity.” Quebec’s new rules offer a range of positive developments for human health and wildlife. The changes will require the following: Prior to any application of atrazine, chlorpyrifos, or neonicotinoid class insecticide, farmers will need the approval of a certified agronomist from the Ordre des agronomes du Quebec (OAQ). Agricultural producers will be required to keep a record of all pesticides applied, as […]

(Beyond Pesticides, February 16, 2018) U.S. Representatives Blumenauer (D-OR) and Jim McGovern (D-MA) this week announced plans to reintroduce the Saving America’s Pollinators Act, (previously H.R. 3040) which suspends the registration of certain neonicotinoid insecticides until the U.S. Environmental Protection Agency conducts a full scientific review that ensures these chemicals do not harm pollinators. Beyond Pesticides joined Rep.

(Beyond Pesticides, February 15, 2018) The U.S. Environmental Protection Agency (EPA) settled claims against pesticide giant, Syngenta, after dozens of workers in Kuai, Hawaii were exposed to the neurotoxic pesticide chlorpyrifos in 2016 and 2017. EPA backed away from the $4.8 million settlement that it was initially seeking from Syngenta and negotiated a civil penalty of $150,000. Nineteen workers were exposed to chlorpyrifos after Syngenta sprayed the insecticide on a field of genetically engineered (GE) corn at its Kekaha farm. According to the complaint, the workers were allowed to reenter the field before the reentry period expired and without protective equipment. Ten workers were taken to the hospital and three were held overnight. This incident occurred in 2016, however a second incident occurred in 2017 when Syngenta failed to post warnings for worker crews containing 42 employees after applying chlorpyrifos. At the time of the incident, an inspector from the Hawaii Department of Agriculture (HDOA) was present on the Syngenta farm, which triggered an immediate investigation from the state. Consequently, a civil administrative enforcement action was brought against Syngenta seeking $4.8 million for violating multiple federal statues including worker protection standards, allegedly affecting as many as 77 workers and leading […]

(Beyond Pesticides, February 12, 2018)  The most recent findings on the development of Parkinson’s disease after exposure to the highly toxic paraquat add to the well-established body of scientific literature linking the herbicide to Parkinson’s — which should lead to finally eliminating the use of the herbicide in the U.S. The chemical was banned in the European Union in 2007, and many health groups, including Beyond Pesticides and The Michael J. Fox Foundation for Parkinson’s Research, are calling on the U.S. Environmental Protection Agency (EPA) to stop the use of paraquat by denying its upcoming reregistration. In addition to its connection with Parkinson’s disease, paraquat is known to be highly acutely toxic. By generating free radicals, it essentially burns its way through the body, targeting the lungs —causing lung fibrosis— and other organs. Most acutely toxic exposures result in death, sometimes delayed by as much as three weeks. Although paraquat is a restricted use pesticide (RUP), EPA is proposing to eliminate the minimum age for applying RUPs, which would permit teenagers to use it. Tell EPA and Congress to ban paraquat! This link will send the following message to EPA and your Congressional delegation: I urge EPA to join other countries […]

(Beyond Pesticides, February 9, 2018) Attorneys General in eleven states join Monsanto and the National Wheat Growers Association last month in challenging California’s listing of glyphosate as a carcinogen under the state’s Proposition 65 law. California added glyphosate to the list of cancer-causing chemicals in July 2017, but has since been attacked by Monsanto and its allies for carrying out state law that requires carcinogens to be labeled and monitored. The plaintiffs, led by the National Association of Wheat Growers, argue that listing glyphosate as a carcinogen under Prop 65 will irreparably harm the agriculture industry, adversely affecting farmers and consumers throughout the U.S. The case, seeking a stay of the listing, was filed in the in Federal Court in the Eastern District of California in November, 2017. Earlier last year, Monsanto lost its case before a state Superior Court in which it sought to stay the Prop 65 listing. Idaho, Indiana, Iowa, Kansas, Louisiana, Michigan, Missouri, North Dakota, Oklahoma, South Dakota and Wisconsin have filed an amicus brief in support of the preliminary injunction sought by agriculture groups against California’s Prop 65 regulation. The U.S. Chamber of Commerce and the California Chamber of Commerce filed their own amicus brief in support of […]

(Beyond Pesticides, February 8, 2018) New trials are being launched in the United Kingdom (UK) to monitor fields that have long strips of wildflowers planted through croplands to boost natural predators and potentially reduce pesticide spraying. The large-scale trials are meant to determine how effective these strips can be as a tool for practitioners wishing to enhance biological pest control in the field. The field trials, carried out by the Centre for Ecology and Hydrology (CEH), are being conducted on 15 large arable farms in central and eastern England and would be monitored for five years. Until now, wildflower strips have been placed at the edge of fields as refuges. However, natural predators in these strips would be unable to access the center of large planted fields, and thereby unable to effectively target pests that are in the fields. In the new trials, six-meter wide strips of annual wild and cultivated plants – with 13 to 16 species – will be planted 100 meters apart so that predators will be able to attack aphids and other pests typically found in fields. The researchers at CEH’s ASSIST program (Achieving Sustainable Agricultural Systems) will determine whether in-field strips are feasible tools for […]

(Beyond Pesticides, February 7, 2018) New data from the California monarch butterfly count indicate that the western population of the species is continuing to decline at an alarming rate, with scientists and conservation groups pointing to man-made factors like logging, climate change, and herbicide use on genetically engineered (GE) crop fields as primary drivers. The annual California count of western monarch butterflies stationed volunteers at 262 sites, more than ever before, yet at 200,000 butterflies counted, the numbers nearly matched the lowest level recorded this decade, when only 145,000 butterflies were seen in 2012. The decline of these iconic butterflies demands swift action from lawmakers and regulators to protect their dwindling numbers. Dramatic declines in monarch populations mirror continuing declines in honey bees and other wild pollinator species. Species declines may be even broader than pollinators, affecting all insects in general. Research from Germany recently found that insect abundance declined 75% over the last 30 years, owing the results primarily to agricultural intensification. The western population of monarch butterflies – those found west of the Rocky Mountains – overwinter in coastal California forests. Throughout the warmer months, female butterflies will lay eggs only on milkweed, making these plants critical to […]

(Beyond Pesticides, February, 6, 2018) Scientists, doctors, and environmental groups are pushing back against the Environmental Protection Agency’s (EPA) efforts to purge academic scientists who had previously received EPA grants from sitting on the agency’s advisory committees. Last October, EPA issued a new policy that changes the makeup of its advisory boards by limiting the participation of scientists from academia and nonpartisan nonprofit organizations. Critics say the change attempts to fill these advisory committees with more industry-friendly officials whose belief systems are anti-environmental protection. On January 23, 2018, a group of scientists filed suit against EPA, citing the directive as arbitrary, without any factual or legal grounding and in violation of the Federal Advisory Committee Act, which requires advisory committees to be fairly balanced and protected from inappropriate influence by the appointing authority. In 1978, Congress directed the EPA to establish the Science Advisory Board, which today is a 47-member panel, to provide scientific advice to the Administrator. EPA Administrator Scott Pruitt announced in October that he would exclude anyone from serving on any of the 23 EPA scientific advisory boards if they had received EPA grants to fund any of their research. Administrator Pruitt claims the policy change will prevent conflicts of interest. But, […]

(Beyond Pesticides, February 2, 2018) California regulators may be drastically underestimating chemical-intensive agriculture’s contribution to nitrogen oxide (NOx) caused air pollution, acid rain, and respiratory illness in the state, according to a new study published in Science Advances by researchers at University of California, Davis. While NOx  pollution is usually associated with energy production and vehicle emissions, fertilizer use on crop fields is contributing to significant air pollution problems. Advocates say that the study is an urgent call for farmers to eliminate dependency on soluble, synthetic, nitrogen-based fertilizers and adopt the use of insoluble soil amendments that support soil biology that provide plants with nutrients. NOx gasses are major sources of pollution in the U.S. and throughout the world, and include the compounds nitrogen oxide (NO) and nitrogen dioxide (NO2). Chemical-intensive, synthetic nitrogen fertilizers are applied in a form that is readily available to plants, while organic nitrogen fertilizers require the biological life in the soil to break down the fertilizer into a form that plants can use. These nitrogen fertilizers that are not immediately taken up by plants can cause pollution problems. Natural nitrogen in the atmosphere must be transformed to be able to be used by organisms as […]

(Beyond Pesticides, February 1, 2018) Scientists at the European Institute for the Biology of Aging are finding new information about how Parkinson’s disease manifests itself after exposure to the herbicide paraquat, in hopes of finding ways to prevent the progression of the disease. Despite a well-established body of scientific literature linking the paraquat to Parkinson’s, and a ban on the use of the chemical in the European Union that dates back to 2007, its use is still permitted in the U.S. Many health groups, including Beyond Pesticides and organizations like the Michael J Fox Foundation are calling on the U.S. Environmental Protection Agency stop the use of paraquat by denying its upcoming reregistration. Published in the journal Cell Reports, this new research on Parkinson’s investigates the impact of “senescent” cells in the body. Senescent cells are those which, despite being able to divide, stop doing so in response to stress. This is an anti-cancer mechanism, as stress would otherwise cause the cells to multiply unchecked and create malignancies. Researchers suspected that despite the benefit of stopping cancer, senescent cells may be causing other problems in the body. Rather than dying, these cells can cause inflammation in the area around where […]

(Beyond Pesticides, January 31, 2018) Woolworths, one of Australia’s largest retailers, has decided to stop selling neonicotinoid products (neonics) linked to global declines in bee populations. This is the latest retailer in Australia to announce commitments to stop supplying the bee-toxic products. After thousands of Australians signed a petition calling on retailers to stop selling insecticides containing neonicotinoids, Woolworth announced it has, in fact, succumbed to public pressure and would join Bunnings Warehouse, Mitre 10 and Coles stores in pulling neonic products from their shelves. The week prior, retail chain Bunnings announced it would pull all items containing neonicotinoids from their shelves. Woolworth said it would stop selling the products by June 2018. The retail commitments come as a result of efforts launched by global consumer group SumOfUs that called on Australian retailers to stop selling insecticide products containing neonicotinoids, including the popular home and garden product, Confidor, which has been stocked by Woolworths and contains imidacloprid as the active ingredient. According to Australia’s The New Daily, about one-third of Australian fruit and vegetable crops are reliant on pollination. Speaking on the ban of neonic products, Katja Hogendoorn, PhD, of University of Adelaide, who researches the behavioral ecology and evolution of native bees, […]

(Beyond Pesticides, January 30, 2018) New data from the U.S. Geological Survey (USGS) reveals the year-round presence of neonicotinoids (neonics) in the Great Lakes – the world’s largest freshwater ecosystem. Neonics, which are highly toxic to aquatic organisms and pollinators, are prevalent in the tributaries of the Great Lakes with concentrations and detections increasing during planting season. This new data adds to burgeoning demand for a federal ban of these insecticides in order to safeguard vulnerable aquatic ecosystems and pollinators. The study, “Year-round presence of neonicotinoid insecticides in tributaries to the Great Lakes, USA,” sampled ten major tributaries to the Great Lakes from October 2015 to September 2016. Neonicotinoids were detected in every month sampled. At least one neonicotinoid was detected in 74 percent of the samples, with 10 percent of samples containing three neonicotinoids. The most frequently detected neonicotinoid was imidacloprid (53%), followed by clothianidin (44%), thiamethoxam (22%), acetamiprid (2%), and dinotefuran (1%). The detections of clothianidin and thiamethoxam are significantly correlated with the percentage of agricultural land use. Similarly, concentrations increased in the spring and summer months when the planting of neonic-coated seeds and broadcast applications are the highest. For instance, in the agriculturally dominated basin (corn and soybean) […]
