(Beyond Pesticides, November 27, 2018) The U.S. Environmental Protection Agency (EPA) ignored the input of an expert weed scientist on the controversial herbicide dicamba, bending to Bayer’s Monsanto and the pesticide industry, according to emails obtained by the Arkansas Democrat and Chronicle (ADC) through a Freedom of Information Act request. The scandal centers on the recent re-approval of the pesticide, a highly volatile and drift-prone herbicide that has become a serious problem for many farmers and state regulators. As top-level EPA officials continue to work with industry to subvert their own agency’s scientific findings, more and more consumers are moving to organic products in order avoid the pesticide risks government regulators ask consumers to accept. Emails ADC received indicate that Jason Norsworthy, PhD, a weed scientist with the University of Arkansas, worked closely with Bayer’s Monsanto in conducting field trials this past summer, but found high volatility and drift of the company’s new dicamba-based herbicide XtendiMax. The product was developed in the face of widespread resistance to glyphosate-based herbicides in genetically engineered (GE) farm fields. However, recent accounts from farmers in the south and midwest indicate that, not only is the switch to dicamba unhelpful  in eliminating drift and reversing escalating weed resistance, its […]

(Beyond Pesticides, November 15, 2018) Neonicotinoids are widely known for their link to declining pollinator populations, but new research finds that the ill effects of these chemicals also extends to amphibian populations. In a study published late last month, scientists from the National Wildlife Research Center in Ottawa, Canada found that chronic exposure to real-world levels of the neonicotinoid imidacloprid limits the ability of juvenile wood frogs to escape a predator attack. This research adds additional evidence that neonicotinoids are harming aquatic food chains, and reinforces calls for U.S. regulators to follow the science and adequately restrict these toxic pesticides. Researchers investigated the impact of neonicotinoids on the post-tadpole life stage of wood frogs, which has been identified as critical to sustaining viable populations of the species. Rather than determine acute impacts that assess how lethal a pesticide is, scientists opted to observe how wood frog behavior changes as a result of chronic, real-world exposure scenarios. In particular, scientists sought to figure out whether exposure resulted in an altered behavioral response to the presence of a predator. As tadpoles, wood frogs were chronically exposed to real world levels of imidacloprid (1, 10, and 100 micrograms/liter), while others were left unexposed […]

(Beyond Pesticides, November 14, 2018) Monarch butterflies are in the midst of a staggering decades-long population decline that has rapidly accelerated since 2005, research published by an international team of scientists and the University of Florida last month indicates. According to data meticulously collected by researchers, monarchs making their way to central Florida after emerging from their breeding grounds in Mexico have declined by 80% over the last decade and a half. This is roughly the same time frame at which beekeepers began to see precipitous declines in managed honey bee colonies. Researchers point to industrial development and increasing pesticide use as factors that have accelerated the decline of this iconic species. “A broad pattern is that 95 percent of corn and soybean products grown in the U.S. are Roundup Ready crops that resist glyphosate,” said study coauthor Earnest Williams, PhD, of New York’s Hamilton College in a press release. “That has a national impact. What’s really needed are patches of native vegetation and nectar sources without pesticides. It’s not just for monarchs but all pollinators.” Beginning in 1985, renowned monarch expert Lincoln Brower, PhD and his team monitored monarch populations at a pesticide-free cattle pasture south of Gainesville, FL. […]

(Beyond Pesticides, November 9, 2018) A Tunisian study (published in January 2018) on the effects in pre-pubertal mice of exposure to malathion — an organophosphate pesticide first registered for use in the U.S. in 1956 — demonstrates significant distortion of liver and kidney biochemistry and function in the animals. Deleterious effects include compromise of feeding ability, metabolism performance, neurologic deficits, reduction of overall body weight, and simultaneous increases in the weights of livers and kidneys, with structural anomalies and lesions in those organs. Organophosphates (OPs) have raised alarm bells for years. Some, such as chlorpyrifos and diazinon, have had their registrations cancelled for household uses because of the extreme health risks to children, but agricultural, golf course, and “public health” (mosquito control) uses remain commercially available and in use. Recently, Beyond Pesticides reported on research whose investigators support — and called publicly for — a worldwide ban on the compounds because of the serious health and environmental risks they pose, particularly for children. Beyond Pesticides has written extensively on OP pesticides, including malathion and chlorpyrifos. Both are used widely in agriculture. Chlorpyrifos has been the subject of quite a ping-pong match in recent years: a scheduled ban by the Environmental Protection […]

(Beyond Pesticides, November 8, 2018) Two months after publishing its first series of tests, part two of an Environmental Working Group (EWG) study finds residues of Roundup’s active ingredient, glyphosate, in all General Mills’ Cheerios and PepsiCo’s Quaker Oats products sampled. Health advocates are expressing concern about the consequences of chronic glyphosate exposure, and say U.S. federal agencies must limit the herbicide’s use on oat-based breakfast foods regularly marketed to children. In addition, organic itself is under threat, as chemical-intensive management practices undermine the future of the growing organic movement. In this second round of testing, EWG scientists purchased products around San Francisco and Washington DC. 28 samples of conventional and 16 samples of organic oat products were collected. Approximately 300 grams of each General Mills and PepsiCo product were packaged and shipped to Anresco Laboratories, in San Francisco. Detected glyphosate residues were compared to EWG’s own health benchmark of 160 parts per billion (ppb). This benchmark is based on risks of lifetime exposure and what EWG scientists consider allowable and protective of children’s health with an adequate margin of safety.  EWG’s results detected glyphosate residues in all 28 samples of conventionally grown oat products. The vast majority (all but two) […]

(Beyond Pesticides, November 2, 2018) A group of leading toxics experts, who published a paper in the journal PLOS Medicine on their research on organophosphate exposure during pregnancy and impacts on child development, are calling for a ban on organophosphate pesticides. The study evaluates current science on the risks of this class of compounds, produced by Corteva Agriscience (formerly Dow AgroSciences); its conclusions warn of the multitude of dangers of organophosphates for children, and makes recommendations for addressing these risks. The experts conclude that: (1) widespread use of organophosphate (OP) pesticides to control insects has resulted in ubiquitous human exposures; (2) acute exposures to OPs is responsible for poisonings and deaths, particularly in developing countries; and (3) evidence demonstrates that prenatal exposures, even at low levels, put children at risk for cognitive and behavioral deficits, and for neurodevelopmental disorders. Among the authors’ recommendations are these: Governments and subsidiary agencies, including the Environmental Protection Agency (EPA), should phase out chlorpyrifos and other organophosphate pesticides; ban non-agricultural uses of OP pesticides (including in household products); monitor watersheds and drinking water sources of human exposure; promote the use of integrated pest management (IPM) through incentives and training; and establish pesticide use and illness reporting […]

(Beyond Pesticides, November 1, 2018) A new study offers fresh evidence that wild bumblebee pollinators are particularly vulnerable to the impacts of neonicotinoid (neonic) insecticides, finding that exposure to these compounds interferes with mating success and population stability. Researchers from Worcester Polytechnic Institute in Massachusetts, measuring real-world harms of neonicotinoids, indicate that the impacts they found to bumblebee “reproducers,” namely queen and drone (male) bees, does not bode well for the array of plant species that relies on them. Though advocates warn that destabilizing managed pollinators could threaten U.S. food production and exports, with food prices increasing as cost of bringing pollinators to farms increases, the study’s authors and advocates insist that the impacts of such widespread poisoning of wild bees could be felt well beyond agriculture. Researchers in the lab compare behavioral and psychological responses of virgin queens, workers, and male Bombus impatiens from multiple colonies to field-realistic doses of the neonicotinoid clothianidin. While every bee was given a replenishing supply of pollen based on body weight and energy demands, four distinct concentrations of diluted analytical-grade (pure) clothianidin (including a control with no pesticide added) were mixed into a nectar-like solution and fed to the bumblebees orally for 5 […]

(Beyond Pesticides, October 25, 2018) A study published last month in Scientific Reports finds that eating sunflower pollen significantly reduces protozoan infection in bumblebees. Studying ecosystem services and what she calls “floral rewards,” evolutionary ecologist Lynn Adler, Ph.D. at the University of Massachusetts Amherst says sunflowers may provide a long sought after solution for improving bees’ immune system response to both disease and parasites. The researchers studied the protozoan Crithidia bombi, a common parasitic infection of bumble bees, known to impair learning and foraging, shorten lifespan and destabilize colony hierarchies by impacting queen bee behavior. From the outset of the study, Dr. Adler says, “the more sunflowers were grown at the farm, the lower the Crithidia load for the bees at that farm.” Knowing pollinators eat pollen as a source of protein and healthy fats, Dr. Adler hypothesized that both pollen and nectar might have medicinal effects against disease and parasites. However, her experiment did not show consistent results with nectar. After bees in the lab were starved for 4-6 hours, researchers fed individual worker bees from small colonies a drop of fructose fluid containing 6,000 Crithidia cells, being the approximate concentration bees may encounter in the wild while foraging. After […]

(Beyond Pesticides, September 12, 2018) The city of Amsterdam, Netherlands is leading global bee recovery efforts by increasing its diversity of wild pollinator species, according to reporting and an analysis by NBC News. A new map published by the city identified 21 bee species not found in an earlier 1998 survey recorded by Amsterdam officials. The increase has been attributed to a range of pollinator-protective measures, including a ban on bee-toxic pesticides and the planting of native flowers, prioritized by the city government since the turn of the century. Local communities throughout the world can look to Amsterdam for policies and practices that will safeguard their own unique pollinator populations. The NBC News report notes several initiatives undertaken by the Amsterdam government. Many of these measures come out of a $38.5 million fund aimed at broadly improving environmental sustainability. “Insects are very important because they’re the start of the food chain,” said Geert Timmermans, an Amsterdam ecologist to NBC News. “When it goes well with the insects, it also goes well with the birds and mammals.” Insect and bee hotels are often installed in conjunction with the development of green roofs, which are encouraged for all new buildings. And parks […]

(Beyond Pesticides, August 29, 2018) As pesticides drain from agricultural fields, they can poison waterways and coastal areas and harm wildlife. Now, a study finds that a gene that helps terrestrial mammals break down certain toxic chemicals appears to be faulty in marine mammals — potentially leaving manatees, dolphins and other warm-blooded aquatic life more sensitive to toxic pesticides, especially organophosphates. As marine mammals evolved to make water their primary habitat, they lost the ability to make a protein that has the effect of defending humans and other land-dwelling mammals from the neurotoxic effects of certain pesticides. The gene, PON1, carries instructions for making a protein that interacts with fatty acids ingested with food. But that protein has taken on another role in recent decades: breaking down toxic chemicals found in a popular class of pesticides – organophosphates. An inspection of the genetic instructions of 53 land mammal species in the study, “Ancient convergent losses of Paraoxonase 1 yield potential risks for modern marine mammals,” found the gene intact. But in six marine mammal species, Paraoxonase 1 (PON1) was riddled with mutations that made it useless. The gene became defunct about 64 million to 21 million years ago, possibly due to dietary or behavioral changes related to […]

(Beyond Pesticides, August 27, 2018) Beyond the visual and audial charms of some bird species, insect-eating birds play a significant role in controlling pests that can ruin crops or ravage forests. A meta-study by Martin Nyffeler, Ph.D. of the University of Basel in Switzerland finds that globally, birds annually consume 400-plus million metric tons of various insects, including moths, aphids, beetles, grasshoppers, crickets, and other arthropods (invertebrate organisms with exoskeletons, paired and jointed appendages, and segmented bodies, such as insects, crustaceans, and spiders). This research reviews 103 studies that examine the volume of insects consumed by various birds in seven of the world’s major biomes. In consuming such volumes of insects that can inflict damage on crops, trees, and other plants on which organisms may feed or otherwise depend, birds provide significant services to ecosystems, to denizens of habitats, and to human food system and economic interests; they also keep local ecosystems in balance. Threats to birds — and thus, to those ecosystem services — include those from pesticide use. Of the 10,700 known bird species distributed across the planet, more than 6,000 are primarily insectivorous. The study indicates that forest-dwelling birds consume the majority of insects (approximately 300 million metric […]

(Beyond Pesticides, August 13, 2018) Tell USDA to Follow the EU in Classifying New Mutagenesis Techniques as GMO. The Court of Justice of the European Union has highlighted the fact that failing to classify mutagenesis (purposeful changes in DNA) as genetic engineering is a backdoor way of allowing GMOs (genetically modified organisms) without labeling them as such. The court issued an opinion on July 25, saying, “Organisms obtained by mutagenesis are GMOs [genetically engineered organisms] and are, in principle, subject to the obligations laid down by the GMO directive.” Although the opinion does not apply to techniques that “have been conventionally used in a number of applications and have a long safety record,” the court says that member states may subject even those organisms to the obligations of the GMO or other directives. The court finds that the risks of new mutagenesis techniques, may yield results –and risks— similar to those of transgenesis (introducing genes from other organisms), and should thus be regulated as genetically engineered organisms. Tell USDA to classify mutagenesis techniques as GMO. This issue is one on which the Agricultural Marketing Service (AMS) of the U.S. Department of Agriculture requested comment during an informal comment period that ended July […]

(Beyond Pesticides, August 2, 2018) Weed scientists from the University of Missouri (UM) have just published evidence of a water hemp population resistant to six different herbicides. The study is sending shock waves throughout the chemical-intensive agricultural community, particularly in light of the plant’s resistance to 2,4-D. In its reporting on the study, KTIC Rural Radio begged the question, “If we’re already seeing 2,4-D resistance now, what will happen when use of the herbicide becomes even more commonplace?” KTIC is referring to the impending commercialization of products like Enlist Duo, developed by DowDupont in an attempt to address widespread weed resistance to glyphosate. Enlist Duo is an herbicide containing both glyphosate and 2,4-D, and is intended to be sprayed only on crops genetically engineered (GE) to tolerate exposure to both chemicals. However, with growing reports like this, many farmers may begin to rethink their approach. In 2014, a farmer contacted UM indicating that water hemp was not responding to 2,4-D during a regular ‘burndown’ the farmer conducted before planting a new crop. (Chemical-intensive farmers will often use a synthetic herbicide to clear their field for new plantings.) The farmer had also used other herbicides, fomesafen and glyphosate, in this process […]

(Beyond Pesticides, July 30, 2018) In place of open debate, Congressional Republicans have once again used riders in three must-pass funding and authorization bills to remove protection from endangered species. It adds up to a huge attack on an immensely popular law. From wolves and grizzly bears to monarchs and burying beetlehttps://action.beyondpesticides.org/p/dia/action4/common/public/?action_KEY=26387s, everyone is at risk. Wolves could lose protection nationwide. Toxic pesticides could be exempt from environmental review. Threatened wildlife could be forced to wait for lifesaving protection while industry gets the green light to destroy our public lands. And that’s just a glimpse of what Congress is trying to get away with. Tell your U.S. Senators to oppose these attacks on the Endangered Species Act. Avoiding direct conflict with a law supported by about 83 percent of Americans (including a large majority of conservatives), according to an Ohio State University poll, Congress has launched hundreds of backdoor attempts to gut the Endangered Species Act and sidestep the laws that protect our air, water, and public lands. If passed, they would change which species get protected, how critical habitat is chosen, and whether climate change can be considered a factor at all. The sneak attacks include: National Defense Authorization Act: […]

(Beyond Pesticides, July 26, 2018) A legal complaint filed by a Kansas farmer claims industry giant, Monsanto, knew its new dicamba-formulated product would harm other crops, but marketed and sold it anyway, damaging thousands of acres of crops. The lawsuit, filed by 4-R Farms based in Corning Kansas, lost over 200 acres of soybeans. This is the latest in a string of lawsuits Monsanto is facing. Farmers in Arkansas, Missouri, and elsewhere have been hit with crop losses as a result of the dicamba damage. Advocates  and victims of damage argue that Monsanto places profits ahead of possible damage to crops when it markets seeds resistant to a powerful weedkiller before making a less volatile herbicide available. This, according to the lawsuit filed in court. The petition, filed last week, could be the catalyst for a class action lawsuit of Kansas farmers against Monsanto, which faces a growing docket of legal challenges. The lawsuit also names chemical company BASF as a co-defendant. BASF is facing its own mounting pile of lawsuits over dicamba. The lawsuit requests unspecified damages and a trial by a federal jury in Topeka. Monsanto marketed its new line of dicamba products, Xtend, to go hand in hand with […]

(Beyond Pesticides, July 19, 2018) A variety of bentgrass, genetically engineered by Scotts Miracle-Gro and Monsanto to tolerate the glyphosate herbicide Roundup, escaped from an experimental field planting in Eastern Oregon 15 years ago, and continues to plague area farmers. Bentgrass is prized by those who maintain golf course greens because of its fine texture and habit of spreading in even, horizontal mats. But the genetically engineered (GE) version has become a giant annoyance for farmers and other growers who battle its spread through the irrigation systems of Malheur County in eastern Oregon. The escape of this GE version of Agrostis stolonifera is especially alarming in Oregon, the grass seed capital of the world. The GE grass showed up after crossing the Snake River from where it had been planted in seed fields in Idaho, despite the fact that the USDA had not approved its release into the seed market. By 2010, farmers and others found it spreading in mats across most of the irrigation canals and ditches that snake across Malheur County. It is now found in Jefferson County, Oregon, and Canyon County, Idaho, as well. The growth habit of the perennial grass is what greenskeepers love, but its persistent […]

(Beyond Pesticides, July 12, 2018) Neonicotinoid insecticides have become notorious for their impacts to insect pollinators like bees and butterflies, but research finding the presence of these chemicals in wild turkeys is raising new concerns about the ubiquitous nature of these chemicals once released into the environment. Published in Environmental Science and Pollution Research by a team from the University of Guelph (UG), this new study highlights the broader effects of neonicotinoids on wildlife, and underlines calls to restrict the use of these products in favor of a more sustainable pest management approach. Looking at roughly 40 wild turkeys in southern Ontario, researchers found 10 that contained pesticide residue in their livers. Claire Jardine, PhD, pathobiology professor and study co-author notes that wild turkeys in agricultural regions are more likely to be contaminated. “Wild turkeys supplement their diet with seeds from farm fields,” she indicated in a press release. The agrichemical industry coats a majority of corn and soybean seeds with neonicotinoids prior to planting. Because of their systemic nature, neonicotinoids are incorporated the seedlings as they grow, with the promise by the industry that this will alleviate pest pressure. However, a significant body of research, including EPA studies, have […]

(Beyond Pesticides, July 9, 2018) The Center for Biological Diversity (CBD) is urging the U.S. Fish and Wildlife Service (FWS) to take action to protect 23 wildlife species in the Southeast that are at risk of extinction. Citing deep concerns about unprecedented assaults on the Endangered Species Act (ESA), CBD’s letter reiterates the critical need for FWS to provide timely protection to the most critically imperiled species. Urge FWS to provide Endangered Species Act protection for 23 species in the Southeast. Urge your U.S. Senators and Representative to support the ESA’s scientific review process and protect endangered and threatened species and their habitats. CBD’s letter highlights the plight of 23 freshwater animals and plants, including the southern snaketail and the sunfacing coneflower, and the failure of FWS to meet its deadlines for issuing proposals on species determined “may warrant protection.” CBD urges FWS to follow the law –to review and publish species protection proposals. A declining budget and opposition from the Trump administration are stalling these critical protections. The Trump administration has proposed slashing the budget for endangered species listings by half, from $20.5 million to $10.9, and to prioritize delisting species rather than granting protection to new ones. These budget […]

(Beyond Pesticides, July 6, 2018) Two years ago, thirteen bald eagles were found dead on a farm in Maryland. Now the investigation has revealed that these birds died after ingesting the highly toxic pesticide, carbofuran. Carbofuran, whose use has been phased out in the U.S., is so toxic to birds that one granule is all it takes to kill. Irresponsible and illegal use of pesticides is still responsible for primary and secondary poisonings of wildlife, as is the case of these bald eagles. According to the necropsy results by U.S. Fish and Wildlife Service (FWS), which analyzed six of the thirteen eagle carcasses, five of the carcasses were found to have undigested raccoon remains in their systems. Carbofuran was detected in the stomach and/or crop contents of all birds, as well as on the partial remains and fur of a raccoon that was found nearby. The granular form of carbofuran has been blamed for the deaths of more than a million birds in the U.S. who mistook the granules for seed. The granules were finally banned in the early 1990s, while the liquid formulation was banned on food crops in 2009, although the painfully slow process of cancellation by the U.S. […]

(Beyond Pesticides, June 27, 2018) Farm Bill Headed for a Showdown on Key Environmental, Public Health, and Organic Issues With a flawed bipartisan Farm Bill expected to sail through the U.S. Senate this week, we need to turn our attention to the upcoming House-Senate Conference Committee that will attempt to resolve differences between the Republican House bill (with no support from Democrats) and the Senate bill. Despite some advances in the Senate Farm Bill for the organic market, including boosts to organic research funding, some provisions to address fraudulent imports, some enhanced conservation programs, and maintaining certification cost-share programs, the Senate bill contains troubling language affecting organic standard setting that could open the door to more damaging provisions in the House bill. It’s like fixing up a house while allowing the foundation to crumble. Tell your U.S. Senators and Representative to protect organic in the Farm Bill, remove any changes to the organic standard setting process, and uphold environmental protections. Beyond Pesticides opposes any provisions in the Farm Bill that amend the standard setting procedures of the federal organic law and believes that no improvements are worth the damage that can be done to the standard setting process and public […]

(Beyond Pesticides, June 21, 2018) In a letter sent by the Center for Biological Diversity (CBD), the U.S. Fish and Wildlife Service (FWS) is being urged to complete status reviews and listing proposals for 23 wildlife species in the Southeast that are at risk of extinction. Citing deep concerns about unprecedented assaults on the Endangered Species Act (ESA), the letter reiterates the critical need for FWS to provide timely protection to the most critically imperiled species. Highlighting the plight of 23 freshwater animals and plants, like the southern snaketail and the sunfacing coneflower, and the consideration by the Trump Administration to withdraw ESA findings for dozens of species, CBD submitted the letter, dated June 8, 2018, urging FWS to follow the law, and review and publish species protection proposals. CBD initiated a review of 61 species for which the group had already filed a petition seeking ESA protections. This came after the Trump administration’s unprecedented move to reverse an Obama-era decision to review the status of the species because available information indicates they may warrant listing. CBD first petitioned FWS for their protection in 2010. Hundreds of other highly imperiled species are similarly awaiting decisions, but, according to CBD, a […]

(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 4, 2018) As the deadline approaches for regulations on labeling genetically engineered (GE or GMO —genetically modified organism) food, the U.S. Department of Agriculture (USDA) has proposed a rule that fails in every important respect: It allows information to be conveyed by QR codes, whose use requires a cell phone (with camera function) and a reliable broadband connection. It allows GE food to be identified as “bioengineered” OR by a smiley-faced symbol containing the letters “be.” It does not cover highly processed GE foods, like vegetable oils or sugar, and does not include newer genetic engineering techniques, such as CRISPR (a gene editing tool). Implementation is delayed. USDA is accepting comments through Regulations.gov. For quick copy and paste, use the text below to comment at regulations.gov. Add a personal message at the beginning about why this is important to you, if possible. Tell USDA We Need Honest, Transparent, Informative GE/GMO Labeling Suggested Comments: As a consumer, I have a right to know whether my food is produced using genetic engineering. As USDA finalizes labeling regulations, please ensure that labels are honest, transparent, and informative by adopting the following policies: Reject package labeling with unreliable “QR codes” and other […]
