(Beyond Pesticides, June 20, 2018) Bumblebee queens that wake up from hibernation to a neonicotinoid-contaminated, monofloral landscape take longer to set up their nest and die-off at higher rates, according to new research from the University of California, Riverside (UCR) published in the journal Proceedings of the Royal Society B.  While this is the first study to evaluate multiple stressors – pesticide exposure and a monotypic diet – on bumblebee pollinators as they initiate a new colony, it is far from the first to conclude that the neonicotinoid class of insecticides result in unacceptable adverse impacts to insect pollinators. With Pollinator Week 2018 underway, advocates say it is time that the U.S. catches up to the European Union and Canada and starts to ban the use of bee-toxic neonicotinoid insecticides. Bumblebee queens only live long enough to produce one colony. After establishing a colony over the spring and summer months, by fall a new queen hatches and the old queen dies. The new queen leaves the nest and mates, then goes underground to seek shelter and hibernate over the winter. If she makes it through the winter, the single queen will then emerge in spring to begin her own colony […]

(Beyond Pesticides, June 19, 2018) Some 200 members of a French beekeeping cooperative in the northern Aisne region have sued Bayer — on the same day the giant chemical company’s acquisition of Monsanto was finalized — after discovering that their honey was contaminated with toxic glyphosate, a known endocrine disruptor and probable human carcinogen (according to the World Health Organization’s International Agency for Research on Cancer). Monsanto is the long-time manufacturer of Roundup, the popular glyphosate pesticide; Bayer now owns not only the company, but also, the liabilities that come with it, including the “Monsanto” name. Environmental activists had denounced the merger, which creates an agrichemical leviathan that promotes use of chemical herbicides and genetically engineered/modified (GE/GMO) seeds. The beekeepers’ suit was filed in early June after Famille Michaud, a large French honey marketer, detected glyphosate contamination in three batches from one of the coop’s members — whose hives happen to border large fields of rapeseed, beets, and sunflowers. Glyphosate is commonly used in French agriculture; President Emmanuel Macron has vowed to ban its use by 2021. Emmanuel Ludot, a lawyer for the cooperative, is looking for an outcome that includes mandated investigation of the extent of glyphosate contamination of honey, and […]

(Beyond Pesticides, June 14, 2018) With nearly 40% of Americans diagnosed as clinically obese, leading to health care costs estimated at over $200 billion, researchers are focusing on ways individuals can reduce their exposure to chemicals that contribute to weight gain regardless of diet or exercise. These chemicals, known as “obesogens,” include a range of consumer products, from pesticides to plastics and flame retardants. While diet and exercise remain critically important to fighting the ongoing obesity epidemic, obesogens may be working to increase appetite, fat storage, or make it more difficult for the body to shed fat once it is gained. In a presentation at the European Society for Endocrinology in Barcelona, researchers from the Universities of Aveiro and Beira Interior, Portugal identified ways these chemicals are entering our environment, and good habits to employ in order to reduce obesogen exposure. “Obesogens can be found almost everywhere, and our diet is a main source of exposure, as some pesticides and artificial sweeteners are obesogens. Equally, they are present in plastics and home products, so completely reducing exposure is extremely difficult – but to significantly reduce it is not only feasible, but also very simple”, lead researcher Ana Catarina Sousa, PhD, […]

(Beyond Pesticides, June 8, 2018) In the wake of U.S. Department of Justice (DOJ) approval of the buyout of Monsanto by Bayer, the new mega-corporation — now the world’s largest agrochemical and seed company — has announced that it will drop the “Monsanto” name, possibly as soon as late summer, when the acquisition is expected to be completed. Bayer first needs to sell off $9 billion in assets to German chemical giant BASF in compliance with a DOJ antitrust agreement that will permit the merger. The union of these two corporations, which joins Bayer’s pesticide business with Monsanto’s genetically engineered (GE) seed operations, faced vigorous opposition from health and environment advocates both in the U.S. and abroad. Fortune magazine has pointed out that dropping a well-known name is unusual, but given that Monsanto is one of the world’s most-hated companies, perhaps the move is understandable. Ditching the “Monsanto” moniker is reportedly one aspect of a coming Bayer campaign to regain public trust and make efforts to engage with critics, according to Bayer spokespeople. Liam Condon, president of Bayer’s Crop Science Division, has said, “Just changing the name doesn’t do so much — we’ve got to explain to farmers and ultimately to […]

(Beyond Pesticides, June 7, 2018) Health Canada is proposing to phase out a number of uses of neonicotinoids in order to mitigate risks to pollinators. The agency has completed its review of clothianidin and thiamethoxam — two neonicotinoids that have been linked to pollinator decline and finds risks of concern for bees. However, these measures do not go as far as those recently made in the European Union, but further than label restrictions issued by the U.S. Environmental Protection Agency (EPA). Health Canada concluded its Pollinator Re-evaluation for clothianidin and thiamethoxam after examining hundreds of laboratory and outdoor field studies that examined the possible effects on bees from wide-ranging situations. The agency finds that uses of these neonicotinoids have “varying degrees of effects on bees,” and that some uses “may pose a risk of concern to bees.” However, instead of a complete ban of the neonicotinoids, the agency is proposing mitigation measures to minimize potential exposure to bees, which includes the phase-out of many uses and certain additional product label statements. Clothianidin will see a phase-out of the following uses: Foliar application to orchard trees and strawberries, and Foliar application to municipal, industrial and residential turf sites. There will also […]

(Beyond Pesticides, June 6, 2018) By the close of 2018, three top neonicotinoid (neonic) pesticides, linked to the worldwide decline in bee populations, will be banned for outdoor use in the European Union (EU), based on the General Court of the European Union’s (GCEU) ruling last month. The GCEU, the equivalent of the U.S. Supreme Court, ruled in favor of taking precautionary action to protect pollinators from clothianidin, imidacloprid, and thiamethoxam. This ruling allows for the limited use of neonic-treated seeds grown in permanent greenhouses where contact with bees is not expected. In its lawsuit, multinational seed and chemical companies, Syngenta and Bayer –manufacturers of the neonics in question– argued unsuccessfully that the pesticides do not necessarily harm bees if farmers use them according to label instructions. Syngenta also sought compensation of approximately $435 million to offset market losses resulting from the ban, but that, too, was denied. In rejecting the arguments of Syngenta and Bayer, the high court aligned itself with the European Food Safety Authority (EFSA) and its assessment of the harm caused by the widely used pesticides. EFSA’s updated assessment, released in February of this year, provided convincing evidence that neonics represent a risk to wild bees and […]

(Beyond Pesticides, June 1, 2018) States and civil society organizations launched new lawsuits in late May against the Pruitt Environmental Protection Agency (EPA) for its continued attack against farmworker health and safety. Two separate lawsuits, one filed by attorneys general in the states of California, Maryland, and New York, and another by health and justice advocates represented by Earthjustice and Farmworker Justice take aim at EPA’s decision to delay the implementation of training requirements designed to protect farmworkers and their families. This is the latest in a series of lawsuits which began when EPA announced it would delay the Certification of Pesticide Applicators Rule in May of last year. Under the Obama administration, EPA released new rules updating farmworker protections after over 20 years of inaction. These rules are important because unlike your average American worker, farmworkers do not have protections under the Occupational Safety and Health Administration (OSHA). At its introduction, the new standards raised the age to apply toxic pesticides to 18, and improved the frequency and quality of training materials farmworkers are provided, among a number of other positive changes. After EPA announced it would be delaying the implementation of these changes, and reviewing the age requirement, […]

(Beyond Pesticides, May 31, 2018) Deforestation in tropical regions helps spread malaria, concludes a recent research study of the Amazon Rainforest. Published in Nature’s open-access journal, Scientific Reports, the study details researchers’ work, from 2009–2015, comparing patterns of deforestation to rates of malaria in nine states in the Brazilian rainforest. Investigators found that the highest malaria incidence concentrated in impacted patches of forest — areas deforested or otherwise degraded from an unmanaged or more-natural state. These medium-sized patches (from .1 to 5 sq. km. in size) seem to be the “sweet spots” at which wood extraction activity (logging, charcoal production, et al.) correlate most strongly with malarial infection rates. The researchers suggest that the finding is perhaps related to the habitat preferences of the primary malaria vector in the region, Anopheles (Nyssorhynchus) darlingi, which breed most happily in shady, watery, edges of forest habitat. Sixty of the 380 mosquitoes in the genus Anopheles can transmit the malaria parasites. Deforestation fragments the forest landscape, creating more forest “edges,” which means more places for mosquitoes to breed. This fragmentation may also help malaria-carrying mosquitoes spread to other areas as adults: “The new [fragmented] landscape delineated by the pattern of deforestation and soil occupation may favor […]

(Beyond Pesticides, May 29, 2018) The Farm Bill is beginning to move in the U.S. Senate Committee on Agriculture, Nutrition, and Forestry, and your voice is critically needed to help stop provisions that are harmful to health and the environment. Tell your U.S. Senators and Representative that they should vote against the Farm Bill unless harmful provisions to health and the environment are removed. In addition to sending this urgent action on the Farm Bill, consider reaching out to your U.S. Senators and Representative when they return to your state for the Memorial Day holiday. If you’re part of a group, ask for a meeting. If you see them at an event or in town, let them know how important it is to keep the dangerous provisions listed below out of the Farm Bill. The Farm Bill in the U.S. House of Representatives, H.R. 2, reported favorably out of the House Agriculture Committee, is stalled, after being defeated on the floor over unrelated immigration legislation. The House bill is a direct attack on organic standard setting, the authority of local governments to restrict toxic pesticides, and the protection of farmworkers, endangered species, and the environment. Without public outcry, it is likely […]

(Beyond Pesticides, May 25, 2018) The results of a pilot study conducted by an international team of researchers finds that exposure to the herbicide glyphosate results in adverse health effects at levels below those regulators deem “safe” or acceptable. These results represent the first phase of a Global Glyphosate Study based at the Ramazzini Institute in Bologna, Italy, in coordination with the University of Bologna, the Italian National Institute of Health, George Washington University, and the Icahn School of Medicine at Mount Sinai, NY. Researchers are aiming to provide a truly independent, comprehensive evaluation of the risks posed by glyphosate-based herbicides. The pilot study, available now on the research team’s website and later this month in the journal Environmental Health, focused on generating data on how glyphosate effects early-life stages of development. A three-month study on rats, used as a surrogate for human development until 18, exposed the animals to both technical grade glyphosate and the formulated herbicide Roundup. Rats ingested 1.75 miligrams of glyphosate or Roundup per kilogram of body weight each day from the womb until 13 weeks after weening. This is the chronic reference dose used by the U.S. Environmental Protection Agency, and an exposure rate at which the […]

(Beyond Pesticides, May 24, 2018) California’s Department of Pesticide Regulation (DPR) is falling short of protecting vulnerable communities in the state, especially low-income and communities of color. This, according to a new report by California Environmental Justice Alliance (CEJA), which assesses state agencies on eight environmental justice principles. The poor showing by DPR comes at the forefront of reports that the state’s pesticide use has increased, nearing record highs. The findings are from California Environmental Justice Alliance’s (CEJA) 2017 Environmental Justice Agency Assessment, which provides full assessments of nine key agencies in the state including, California Air Resources Board, Department of Pesticide Regulation, and the Department of Toxic Substances Control, and lists an additional six agencies to monitor. The assessment gave the California Department of Pesticide Regulation (DPR) poor grades for its persistent failure to prioritize community health over industry profits. The agencies were judged on eight environmental justice principles, with a score of good, fair or poor for each. DPR’s scores were evenly divided between “fair” and “poor.” Specifically, the report concludes, “Many state agencies are not successfully integrating [environmental justice] into their decision-making. Overall, many state agencies still make decisions that actively harm [environmental justice] communities and fail to […]

(Beyond Pesticides, May 23, 2018) Earlier this month, the Connecticut state legislature voted to ban the use of residential pesticide misting systems. (These are devices that are typically placed outdoors and spray insecticides –mostly in an attempt to control mosquitoes.) This is the latest move from a state legislature that has also recently banned the use of bee-toxic neonicotinoids and stopped the use of hazardous lawn care pesticides on public playgrounds. The vote was unanimous in the state Senate, and won by a count of 132-17 in the state House. The bill is set to become law on May 24, unless Governor Malloy vetoes the legislation, which is not expected. Pesticide misters are machines primarily used to spray mosquito adulticides. Many health advocates have expressed concern that these products, able to spray toxic pesticides on a timer at regular intervals, pose a significant risk to pets and children who can be directly in the path of a mister’s spray. The chemicals employed in these machines are often synthetic pyrethroids, which have been linked to a range of human health effects, from early puberty in boys, to behavioral disorders, learning problems, ADHD, and certain cancers. Neighbors who do not want to be […]

(Beyond Pesticides, May 22, 2018)  A staggering 209 million pounds of pesticides were used in California in 2016, according to the latest data released by the Department of Pesticide Regulation (DPR). This figure refers only to applied “active” pesticide ingredients and not “inerts,” which often account for 80 to 99 percent of pesticide products and can be equally hazardous to human health and the environment. Even though pesticide use in the state has dropped by 1.4 percent from the previous year, pesticide use in 2016 was still the third highest in recorded history, since the inception of DPR’s comprehensive data collection program in 1990. In fact, the total pesticide use was only six million pounds shy of the highest amount ever recorded – 215 million pounds in 1998. The land area treated with carcinogens is as large as the size of New Jersey and Connecticut combined. Nearly 102 million cumulative acres of land were treated with pesticides in the state, ranging in toxicity from low to high risk. Each time an acre is pesticide-treated in a given year, DPR adds the acre to its cumulative list, even if the treatment is repeated on the same land. The 2016 figure represents an […]

(Beyond Pesticides, May 21, 2018)  490,000 Pounds of Toxic Pesticides Sprayed on National Wildlife Refuges in 2016 The nation’s 562 national wildlife refuges play a critical role in protecting fish, plants, and other wildlife. They include forests, wetlands, and waterways vital to thousands of species of plants and animals, including 280 that are protected under the Endangered Species Act. However, private chemical-intensive commercial farming of crops like corn, soybeans, and sorghum has become common on refuge lands, with the increasing use of highly toxic pesticides that threaten the long-term health of sensitive habitats and the creatures who depend on them. The Center for Biological Diversity (CBD) estimates that 490,000 pounds of pesticides were applied to commodity crops like corn, soybeans, and sorghum grown in national wildlife refuges in 2016, the most recent year for which data are available. Tell FWS to take toxic pesticides out of wildlife refuges. The nearly half million pounds of pesticides used on wildlife refuges in 2016 include 2,4-D, dicamba, and paraquat, all of which are toxic to fish, amphibians, crustaceans, and other animals. Also included are 116,200 pounds of glyphosate, the herbicide that has caused widespread decreases in milkweed plants, helping to trigger the 80 percent […]

(Beyond Pesticides, May 17, 2018)  Among the many reports of the salutary effects of nature on human health and well-being comes new research demonstrating that children who live in “green” neighborhoods have reduced risk of developing asthma. Researchers Jeroen Douwes, PhD and Geoffrey H. Donovan, PhD, of New Zealand’s Massey University (Centre for Public Health Research) and the U.S. Forest Service, respectively, conducted the longitudinal study with New Zealand subjects born in 1998, following them until 2016. The authors say the study results “suggest that exposure to greenness and vegetation diversity may be protective of asthma.” Of concern are the pesticides used in green spaces. See Beyond Pesticides’ brochure, Asthma, Children, and Pesticides and El Asma, los Niños y los Pesticidas: Lo que usted debe saber para proteger a su familia. Also, see Children and Pesticides Don’t Mix. In addition to the well-substantiated benefits of exposure to nature — reduction of the experience of stress; reduction in production of cortisol (the “stress” hormone that is linked to weight gain, hypertension, cardiac disease, weakened immune function, and loss of bone density); improved mental health; better cognitive function; and lower  BMI (body mass index) — this latest research evaluates the impact on children’s risk for asthma.

(Beyond Pesticides, May 16, 2018) Northern Harvest Sea Farms, an ocean-based fish farm in New Brunswick, Canada, was appeared in court yesterday to answer legal charges stemming from the off-label use of an unnamed pesticide added to its operations to combat severe sea lice outbreaks. The company holds nine licenses for farmed Atlantic salmon cages on the Bay of Fundy, as well as for fish farms off the Newfoundland coast. Sea lice outbreaks are a common at over-crowded, ocean-based fish farms because such facilities afford the optimum conditions for rapidly reproducing and spreading lice. In response, some companies have turned to using illegal and off-label pesticide applications to stave off the problem, which causes huge farmed salmon kills. The company was issued a $12,000 fine that was challenged as inadequate by the Grand Manan Fishermen’s Association. Bonnie Morse, project manager for the association told Canadian Broadcasting Corporation (CBC) news, “I think any time there’s a fine that’s a deterrent to illegal activity, it should be an actual deterrent to the activity,” said Morse. “When you’re looking at $1.5 million worth of fish, their actions speak for themselves.” Maria Recchia, the executive director of the Fundy North Fishermen’s Association, questioned the allowance of fish […]

(Beyond Pesticides, May 15, 2018) According to a new report from the Center for Biological Diversity (CBD), hundreds of thousands of pounds of pesticides are sprayed on lands that are designated as refuges for wildlife and protected under U.S. law. Approximately 490,000 pounds of pesticides have been sprayed on crops grown in national wildlife refuges in 2016 alone. Pesticide use in these sensitive areas poses risks to pollinators, aquatic organisms, migratory birds, and other wildlife on refuges that were created to protect them. The report, No Refuge, released last week, analyzes pesticide use on national wildlife refuges using records obtained through a Freedom of Information Act request. The report finds that in 2016 more than 270,000 acres of refuge lands were sprayed with pesticides for agricultural purposes. Five national wildlife refuge systems are identified as most reliant on pesticides for agriculture: Klamath Basin National Wildlife Refuge Complex in California and Oregon, with 236,966 pounds of pesticides; Central Arkansas Refuges Complex in Arkansas, with 48,725 pounds of pesticides; West Tennessee Refuge Complex in Tennessee, with 22,044 pounds of pesticides; Tennessee National Wildlife Refuge Complex in Tennessee, with 16,615 pounds of pesticides; and, Chesapeake Marshlands National Wildlife Refuge Complex on the Eastern Shore of Maryland and Virginia, with […]

(Beyond Pesticides, May 11, 2018) Earlier this month, the U.S. Department of Agriculture (USDA) released its long-awaited proposal for disclosing the presence of genetically engineering (GE) in foods. Much to the disappointment of health, environmental, and consumer advocates, the draft rule appears as an attempt mask or to promote GE products, rather than caution consumers. Concerned individuals can send comments to USDA on the proposed rule through regulations.gov until July 3rd. USDA’s proposal will move forward with wholly insufficient disclosure requirements that the Department’s own study had indicated are discriminatory, according to analysts. Rather than use the phrase “genetically modified,” or “genetically engineered,” or include the acronyms “GE” or “GMO,” USDA is using the term “bioengineered.” The symbols proposed by USDA are a happy, smiling sun that would read either “bioengineered” or “may be bioengineered food.” Of course, such a symbol suggests to consumers that these foods are a positive, rather than concerning addition to a food product. However, USDA is also giving the option of simply including the words “bioengineered food,” “contains a bioengineered food ingredient,” or even leaving that language out and directing consumers to a QR code. A lawsuit by the Center for Food Safety forced USDA […]

(Beyond Pesticides, May 10, 2018) Rodenticides like bromadiolone, used to kill vole populations on farms, act like “super-predators” that imperil ecosystem health, according to preliminary results published by researchers working for the European Union. “Controlling voles with bromadiolone reduces the amount of food available to predators and increases their risk of secondary poisoning when they eat the contaminated rodents,” project researcher Javier Fernandez de Simon, PhD, said in a press release. The study provides a model that may alleviate the impact of rodenticide use and provide a balance between on-farm pest management and sustainability. There are several types of rodenticides available on the market, including acute poisons like strychnine, fumigants like phosphine gas, and anti-coagulants such as warfarin and bromadiolone. Anti-coagulants, the focus of the present study, work by blocking the ability of the body to form blood clots. Animals exposed to bromodialone and other anti-coagulants experience ruptured blood vessels, hair loss and skin damage, nosebleeds, and bleeding gums prior to death. These pesticides are generally applied through secured bait boxes that only allow rodent pests to feed, however secondary poisoning is a common occurrence, leading researchers to dub these rodenticides, in effect, as “super-predators.” Rodents that ingest anti-coagulant pesticides […]

(Beyond Pesticides, May 9, 2018) An insect’s gut microbiome plays an important role in conferring pesticide resistance, according to a new review published in the Annals of the Entomological Society of America. “Whether you’re looking at agricultural pests, household pests like cockroaches, or medical pests like disease-carrying mosquitoes, insects are great at adapting to whatever we throw at them, especially when it comes to different chemicals,” said lead author Jose Pietri, Ph.D to Entomology Today. The review adds to the numerous ways pests can evade the effects of chemical agriculture, reinforcing calls from recent studies showing that the best method of addressing this issue is to simply stop using synthetic pesticides and employ alternative pest management practices. The authors identify two overarching methods through which microbes help confer resistance to toxic pesticides. The first involves the pest accepting a physiological trade-off, where a pest is able to better withstand an insecticide at the cost of losing its ability to regulate certain gut bacterium. For instance, diamondback moths resistant to fipronil and chlorpyrifos are found to contain higher levels of Lactobacillales, Pseudomonadales, and Xanthomonadales bacteria than non-resistant moths. While this trade-off affects the fitness of the organism, alterations of the bacterial […]

(Beyond Pesticides, May 7, 2018) Beyond Pesticides and The Organic Consumers Association (OCA) today responded to a federal judge’s ruling against Monsanto Co.’s motion to dismiss the groups’ lawsuit, filed in April, 2017. The lawsuit challenged Monsanto’s safety claim on its Roundup (glyphosate) products as misleading and fraudulent. Monsanto displays a claim on its Roundup product label that states that the chemicals in the product “targets an enzyme bound in plants but not in people or pets,” when, in fact, the chemical adversely affects beneficial bacteria essential to the gut biome and normal body functions. Jay Feldman, executive director of Beyond Pesticides, the lead plaintiff in the case, said: “In the face of EPA’s poor regulation of pesticides, misleading pesticide product labeling cannot be left unchecked. The court’s decision to allow our case to move forward, in denying Monsanto’s motion to dismiss, is critical to showing that the company is deceiving the public with a safety claim on its Roundup (glyphosate) label. Its advertising and labeling claim that Roundup ‘targets an enzyme found in plants but not in people or pets’ is false, given the devastating harm that glyphosate has on beneficial bacteria in the gut biome. The disruption of the […]

(Beyond Pesticides, May 6, 2018) The Washington State Department of Ecology (Ecology) temporarily denied a permit to spray Willapa Bay and Grays Harbor with the toxic neonicotinoid insecticide imidacloprid. Your comments helped achieve the temporary decision and comments are now needed again to make the denial permanent. The public comment period closes on May 14, 2018. Willapa Bay and Grays Harbor, with a number of unique ecosystems, and among the most pristine estuaries in the U.S., have been targeted with a plan to spray the toxic neonicotinoid insecticide imidacloprid to kill the native burrowing shrimp in beds of commercial Japanese oysters. This insecticide use will have deadly effects on keystone aquatic organisms. Based on a Supplemental Environmental Impact Statement (SEIS) and public input, Ecology temporarily denied the permit. Tell Ecology to restore the bays instead of spraying them! Ecology bases its decision on these factors: Too great an impact on the marine organisms that live in the sediments where the pesticide application is proposed. Too much uncertainty about the long-term impacts associated with this pesticide. Negative impacts on fish and birds caused by killing sources of food and disrupting the food web. Even at low concentrations, imidacloprid has significant impacts […]
