(Beyond Pesticides, June 22, 2018) Mosquito misters pose a threat to human health. They also harm bees and other flying pollinators and are the least effective way to deal with biting mosquitoes. These devices are typically placed outdoors and spray insecticides âmostly in an attempt to control mosquitoes. In May, the Connecticut state legislature voted to ban the use of residential pesticide misting systems. Urge your Governor and state legislators to ban pesticide misters. In addition to the threat to peopleâs health, misters harm pollinators who may be foraging in an area where the devices are used. Studies find that sublethal concentrations of synthetic pyrethroids significantly reduce bee fecundity and decrease the rate at which bees develop to adulthood and reproduce. Field and laboratory studies using pyrethroids have consistently documented decreases in foraging activity and activity at the hive entrance after exposure. While pesticides are regulated by the U.S. Environmental Protection Agency (EPA), pesticide misters and other application devices are not subject to EPA oversight, leaving states with the authority to control their use. Connecticut appears to be the first state to restrict pesticide misting machines through legislation. The state of New York took an administrative approach to regulating these devices, as the commissioner of the […]

(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. Â While this is the first study to evaluate multiple stressors â pesticide exposure and a monotypic diet â 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 â on the same day the giant chemical companyâs acquisition of Monsanto was finalized â after discovering that their honey was contaminated with toxic glyphosate, a known endocrine disruptor and probable human carcinogen (according to the World Health Organizationâs 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 âMonsantoâ 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 beekeepersâ suit was filed in early June after Famille Michaud, a large French honey marketer, detected glyphosate contamination in three batches from one of the coopâs members â 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 18, 2018) At the start of National Pollinator Week, Beyond Pesticides today released its new video, Seeds that Poison âto broaden public understanding of the devastating adverse effects of pesticides on the health of pollinators (bees, birds, butterflies, and other organisms), and the solution in the organic management of agriculture, parks, playing fields, gardens, and lawns. Hazardous pesticides tied to the decline of honey bees and native bees are not permitted in certified organic food production and numerous policies adopted by local governments across the U.S. The accumulated studies and data have found that honey bees and other pollinators, such as native bees, butterflies and birds, are in decline. Scientists studying the issue have identified several factors that are contributing to bee decline, including pesticides, parasites, improper nutrition, stress, and habitat loss. (See Beyond Pesticidesâ What the Science Shows.) Pesticides have been identified in the independent scientific literature as a major contributing factor. Pesticides in the neonicotinoid (neonic) chemical class have been singled out as major suspects due to their widespread use as seed coatings, high toxicity to bees, âsystemicâ nature –neonic chemicals move through the plantâs vascular system and are expressed in pollen, nectar, and guttation droplets– […]

(Beyond Pesticides, June 8, 2018)Â In the wake of U.S. Department of Justice (DOJ) approval of the buyout of Monsanto by Bayer, the new mega-corporation â now the worldâs largest agrochemical and seed company â has announced that it will drop the âMonsantoâ 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 Bayerâs pesticide business with Monsantoâs 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 worldâs most-hated companies, perhaps the move is understandable. Ditching the âMonsantoâ 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 Bayerâs Crop Science Division, has said, âJust changing the name doesnât do so much â weâve 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 âvarying degrees of effects on bees,â and that some uses âmay pose a risk of concern to bees.â 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)Â 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 Unionâs (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 âmanufacturers of the neonics in questionâ 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. EFSAâs updated assessment, released in February of this year, provided convincing evidence that neonics represent a risk to wild bees and […]

(Beyond Pesticides, May 31, 2018) Deforestation in tropical regions helps spread malaria, concludes a recent research study of the Amazon Rainforest. Published in Natureâs open-access journal, Scientific Reports, the study details researchersâ work, from 2009â2015, 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 â 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 âsweet spotsâ 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 âedges,â which means more places for mosquitoes to breed. This fragmentation may also help malaria-carrying mosquitoes spread to other areas as adults: âThe new [fragmented] landscape delineated by the pattern of deforestation and soil occupation may favor […]

(Beyond Pesticides, May 24, 2018) Californiaâs 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 stateâs pesticide use has increased, nearing record highs. The findings are from California Environmental Justice Allianceâs (CEJA)Â 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. DPRâs scores were evenly divided between âfairâ and âpoor.â Specifically, the report concludes, âMany 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 21, 2018)Â Â 490,000 Pounds of Toxic Pesticides Sprayed on National Wildlife Refuges in 2016 The nationâs 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 9, 2018) An insectâs 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. âWhether youâre 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,â 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)Â Beyond Pesticides and The Organic Consumers Association (OCA) today responded to a federal judgeâs ruling against Monsanto Co.âs motion to dismiss the groupsâ lawsuit, filed in April, 2017. The lawsuit challenged Monsantoâs 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 âtargets an enzyme bound in plants but not in people or pets,â 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: âIn the face of EPAâs poor regulation of pesticides, misleading pesticide product labeling cannot be left unchecked. The courtâs decision to allow our case to move forward, in denying Monsantoâs 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 âtargets an enzyme found in plants but not in people or petsâ is false, given the devastating harm that glyphosate has on beneficial bacteria in the gut biome. The disruption of the […]

(Beyond Pesticides, May 1, 2018) On April 27, 2018, European Union (EU) member states backed a proposal to further restrict uses of bee-toxic neonicotinoids finding the pesticidesâ outdoor uses harm bees. These restrictions go beyond those already put in place in 2013, and now all outdoor uses of clothianidin, imidacloprid, and thiamethoxam will be banned. Uses will only be allowed in permanent greenhouses where contact with bees is not expected. This historic move in Europe comes as the U.S. Environmental Protection Agency (EPA) still drags its feet on finding neonicotinoids are too toxic for bees and other organisms and bans their use. According to the European Commission, the protection of bees is an important issue since it concerns biodiversity, food production, and the environment. An EU committee approved the plan to tightly restrict the use of the insecticides, acting upon scientific advice this past February from the European Food Safety Authority (EFSA) to tighten existing restrictions and protect bees, crucial pollinators. EFSA analyzed over 1,500 studies from academia, beekeeper associations, chemical companies, farmer groups, non-governmental organizations, and national regulators, and concluded that neonicotinoids do pose risks to honey bees and wild pollinators. In 2013, the EU placed a ban on […]

(Beyond Pesticides, April 25, 2018) A class-action lawsuit against two manufacturers of neonicotinoid insecticides is moving ahead in Quebec, Canada after an appeal to block the case by the Canadian government and the chemical companies, Bayer and Syngenta, was dismissed. In February 2018, the case, brought by a beekeeper, was allowed to proceed to trial by the Quebec Superior Court. Quebec queen bee breeder, Steve Martineau, conducted tests on water and his dead and dying bees and found traces of neonicotinoids. His suit alleges that Bayer and Syngenta were negligent in the manufacture and sale of neonicotinoids in Quebec, and are responsible for damages that he and other class members suffered under Article 1457 of the Quebec Civil Code. Bayer and Syngenta challenged the application on a number of grounds including the assumption that they had manufactured the neonicotinoids which killed Martineau’s bees. The class in this case was authorized for all persons in Quebec who own or owned bees in the affected area since 2006. Mr. Martineau estimates he has lost about $20,000 a year to present due to the effects of neonicotinoids on his bee population (Martineau v. Bayer CropScience Inc. CALN/2018-007) “We’re suing on behalf of Quebec beekeepers whose bees were […]

(Beyond Pesticides, April, 24, 2018) On April 19, 2018, an Appellate Court in California sided with the State of California, affirming that Monsanto’s glyphosate can be listed as a probable carcinogen under the state’s Proposition 65 and rejecting Monsantoâs challenge to law. The state will not only move ahead with warning labels on products that contain glyphosate but also prohibit discharge of the pesticide into public waterways. Monsanto’s lawsuit challenged the 2015 decision by California’s Office of Environmental Health Hazard Assessment (OEHHA) to list glyphosate, the active ingredient in Monsanto’s herbicide, Roundup, under California’s Proposition 65. Proposition 65 requires notification and labeling of all chemicals known to cause cancer, birth defects or other reproductive harm, and prohibits their discharge into drinking waters of the state. In 2015, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) concluded that glyphosate is “probably carcinogenic.” Under the Labor Code listing mechanism of Proposition 65, substances identified by IARC must be listed in the state of California as known to cause cancer. This listing requires warning labels on products and the listed substances are subject to limits on discharges into surface waters. California added glyphosate to the list of cancer-causing chemicals in July […]

(Beyond Pesticides, April 4, 2018) In late March, the Missouri Department of Agriculture hosted a public hearing to discuss a proposed emergency rule restricting the sale and use of the herbicides dicamba and 2,4-D â which are known for their ability to drift off-site and damage sensitive crops. The emergency rule was introduced to prevent off-label use of specific dicamba or 2,4-D products. Thus far, dicamba is responsible for damaging approximately 325,000 acres of soybeans in the state last year. The proposed rule will stop sales of the herbicides dicamba and 2,4-D between April 15 and October 1 in Missouri. The departmentâs goal is to prevent off-label pesticides from drifting onto neighboring property and damaging other crops. According to the department, if it chooses to pursue an emergency rule, it could become effective as soon as April 1, 2018, and expire 180 days later. The rule also requires registrants to provide a sales record by April 30 for each pesticide sold between October 1 and April 15. A proposed rule will be filed at the same time as an emergency rule to initiate the formal rulemaking process. The draft rule language reads as follows: Pesticides that meet the conditions of this section are […]

(Beyond Pesticides, March 26, 2018) Tell your state AG to join the investigation of the merger of Bayer-Monsanto, the manufacturer of genetically engineered seeds tolerant of its herbicide glyphosate (aka RoundupÂŽ), and Bayer, the manufacturer of neonicotinoid insecticides responsible for pollinator declines, including imidacloprid and clothianidin. The giant seed and pesticide company that would be created by this merger would be a disaster for pollinators, people, and the environment. Farmers overwhelmingly think this mega-merger is a bad idea âa new survey and white paper were released that demonstrate widespread opposition of farmers to this merger. According to the poll, which was conducted by a coalition of farm organizations, 93 percent of farmers surveyed oppose it. More than one million Americans have called on the Department of Justice to stop it. Investigations are ongoing in both the EU and the U.S. Your state attorney general could play a key role in this fight by joining the investigation. Tell your state AG to join the investigation of the Bayer-Monsanto Merger! If this merger goes through, the new company would be the worldâs largest vegetable seed company. It would control seeds for many of the crops we eat regularly â including broccoli, carrots, and onions. It would also be the largest manufacturer […]

(Beyond Pesticides, March 21, 2018) According to a new study published this month in Environment Health, women with high levels of glyphosate in their bodies are more likely to have shorter pregnancies. Shorter pregnancies can lead to children with reduced learning and brain development. This is the first study to suggest that exposures to glyphosate can influence the long-term well-being of children. The study, Glyphosate exposure in pregnancy and shortened gestational length: a prospective Indiana birth cohort study, obtained both urine and drinking water samples from 71 women with pregnancies living in Central Indiana while they received routine prenatal care, and analysed the relationships of glyphosate levels in motherâs urine with fetal growth indicators and gestational length. The researchers found that more than 90 percent of pregnant women had detectable levels of glyphosate where higher glyphosate levels were significantly correlated with shortened gestational lengths, even though the drinking water samples had little to no detectable levels of glyphosate. Women living in rural areas were found to have higher glyphosate levels. The authors note their study is significant because it is the first U.S. study designed specifically to measure prenatal glyphosate exposure in pregnant women to determine its association with adverse fetal […]

(Beyond Pesticides, March 20, 2018) Regulations that separate ingredients in pesticide products as either âother/inertâ or âactiveâ have no scientific basis, according to a new review of the toxicity of formulated pesticide products published in the journal Frontiers in Public Health. Despite widespread awareness that âotherâ or âinertâ pesticidal ingredients present toxicity concerns, only âactiveâ ingredients undergo a full risk assessment, and pesticide products containing both active and inert ingredients are not tested in formulation before being sold to the public. Using glyphosate and neonicotinoid based products as examples, the study recommends sweeping changes to the way pesticide formulations are regulated in the Western world. Inert, or other ingredients ânot disclosed on pesticide product labels, are often adjuvants that are added to a pesticide formulation to modify the effect of the active ingredient. However, they can also be sold separately and used in agriculture where pesticides are often âtank mixedâ on site before application. Adjuvants take many forms, including surfactants, dyes, stabilizers, propellants, emulsifiers, solvents, antifoaming agents, and still other uses. Surfactants, likely the most common adjuvant, are added to a pesticide formulation in order slow the degradation time or improve the penetration of the active ingredient on a target […]

(Beyond Pesticides, March 15, 2018) On Tuesday, a group of 56 scientists studying the effects of neonicotinoids sent a letter to Californiaâs Department of Pesticide Regulation (CDPR) highlighting the threat neonicotinoids pose to the health of Californiaâs waterways. The scientists urge CDPR to take steps to reduce neonicotinoid contamination of the stateâs streams and rivers. This comes as neonicotinoids were recently reported to be pervasive throughout the Great Lakes, and federal assessments confirm high risks to aquatic species. According to the letter, neonicotinoids are already found in California waterways at levels that exceed the freshwater invertebrate aquatic life benchmarks and could harm or kill many sensitive aquatic invertebrate species. Citing a 2016 study by the Xerces Society that found imidacloprid frequently in Californiaâs rivers and streams at levels harmful to species such as mayflies and caddisflies. Imidacloprid samples in California from 2010-2015 showed that 42% (197 of 468) of detections exceeded the acute invertebrate benchmark and all of the detections exceeded the chronic invertebrate benchmark. In certain regions of the state, particularly agricultural areas, the imidacloprid benchmark for acute effects was more frequently exceeded. The scientists note these chemicals can âhave consequences for broader ecosystems. Declines in aquatic invertebrates put other species […]

(Beyond Pesticides, March 14, 2018) The annual count of Monarch butterflies overwintering in Mexico shows declines from last yearâs numbersâa 15 percent decrease âaccording to figures from an official Mexican government count in the winter of 2017. These numbers underscore how at risk the iconic animal is, with a possible collapse of migration if populations are critically low. Monarch butterflies (also known as Eastern Monarchs) embark on an impressive migration every year. Roughly 99 percent of all North American monarchs migrate each winter to oyamel fir forests on 12 mountaintops in central Mexico. Scientists estimate the population size by measuring the area of trees turned orange by the clustering butterflies. But for the second year in a row, its numbers are declining â 2.48 hectares of occupied winter habitat is down from 2.91 hectares last winter. Apart from partial rebounds in the winters of 2001 and 2003, numbers have gone down steadily since 1996. Overall monarchs have declined by more than 80 percent over the past two decades. Earlier this year, Western Monarchs â those found west of the Rocky Mountains â overwinter in coastal California forests, were also found to be declining at an alarming rate, with scientists and conservation groups […]

(Beyond Pesticides, March 12, 2018)Â 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. EFSAâs 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 âThe availability of such a substantial amount of data as well as the guidance has enabled us to produce very detailed conclusions,â said Jose Tarazona, PhD, head of EFSAâs Pesticides Unit in a press release. This is EFSAâs 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 […]
