(Beyond Pesticides, October 4, 2011) In September, Bayer CropScience announced that it plans to phase-out its most acutely toxic pesticides, all remaining World Health Organization (WHO) class I products, by the end of 2012. While this is a positive development, Beyond Pesticides points out that other Bayer pesticides, such as its bee-killing insecticides imidacloprid and clothianidin, will remain on the market. Activists around the globe have mixed reactions to Bayer’s announcement, which comes over 15 years after Bayer first promised to phase-out its WHO Class I products. Philipp Mimkes of the Coalition Against Bayer Dangers based in Germany said, “This is an important success for environmental organizations from all over the world who have fought against these deadly pesticides for decades. But we must not forget that Bayer broke their original promise to withdraw all class I products by the year 2000. Many lives could have been saved. It is embarrassing that the company only stopped sales because the profit margins of these chemical time bombs have fallen so much.” Acutely toxic pesticides with a WHO Class I rating are extremely toxic and present an immediate hazard to farmworkers and others in the vicinity of pesticide applications. The WHO estimates […]

(Beyond Pesticides, September 6, 2011) Scientists in France have discovered that honey bees are at a higher risk of dying from infection by Nosema ceranae (N. ceranae) when they are exposed to low doses of insecticides. The results, presented in the journal PLoS ONE, support the theory that combining more N. ceranae with high pesticide content in beehives could contribute to colony depopulation. The French study, “Exposure to Sublethal Doses of Fipronil and Thiacloprid Highly Increases Mortality of Honeybees Previously Infected by Nosema ceranae,” brought together researchers from the Laboratoire Microorganismes: Génome et Environnment and the Laboratoire de Toxicologie Environnment who utilized their respective skills in parasitology and toxicology to assess the effect of pathogen/toxin interactions on bee health. In the laboratory, the researchers chronically exposed newly emerged honey bees, some healthy and others infected with Nosema ceranae, to low doses of insecticides: fipronil and thiacloprid. They found that the infected bees died when they were chronically exposed to insecticides, even at sublethal doses, unlike the healthy bees. This combined effect on honeybee mortality was observed with daily exposure to extremely low doses (over 100 times less than the LD50 or dose needed to kill 50% of the sample population, […]

(Beyond Pesticides, August 4, 2011) At least 21 different species of weeds are found to be resistant to the herbicide glyphosate, commonly sold as Roundup and used across thousands of acres of “RoundUp Ready” genetically engineered (GE) crops, according to a series of studies in the current issue of Weed Science. Palmer amaranth, one of the weeds discussed in the journal, can reduce yields of cotton by more than 50 percent if there is a density of at least 10 of these weeds per row. Fifty-two counties in the state of Georgia had infestations of glyphosate-resistant Palmer amaranth last year. Studies confirm that the weed, which also competes with soybean, corn, grain sorghum and peanut crops, is also resistant to the herbicide phrithiobac in addition to glyphosate. Over-application and over-reliance by farmers on glyphosate to solve all of their weed problems has led to the proliferation of so-called “super weeds,” which have evolved to survive the treatments through repeated exposure. The most common species which have evolved these traits include pigweed (palmer amaranth), mare’s tail, and ryegrass. The spread of resistance is what has led farmers to increasingly rely on more toxic alternative mixtures, including weed killers like atrazine. There […]

(Beyond Pesticides, July 28, 2011) A new report released last week finds that the U.S. Environmental Protection Agency’s (EPA) voluntary program to evaluate chemicals fails to protect children. According to the evaluation report by EPA’s Inspector General, the Voluntary Children’s Chemical Evaluation Program (VCCEP) was hampered by industry’s refusal to voluntarily collect and submit information and the agency’s failure to regulate under the Toxic Substances Control Act (TSCA) to collect the data. The report states what environmental groups have known for years: “EPA has not demonstrated that it can achieve children’s health goals with a voluntary program.” According to the Inspector General (IG), these failures led to only a fraction of the chemical assessments for the pilot being completed. IG found that VCCEP’s pilot was critically flawed and that the design of the program “did not allow for the desired outcomes to be produced.” It had a flawed chemical selection process and lacked an effective communication strategy. VCCEP is no longer operational and EPA has no plans to revive, replace, or terminate the program. The program was set up as part of the Chemical Right-to-Know Initiative in 1998 to ensure that there are adequate publicly available data to assess the […]

(Beyond Pesticides, July 1, 2011) The U.S. Environmental Protection Agency (EPA) has granted emergency approval for the use of the neonicotinoid pesticide dinotefuran to control brown marmorated stink bugs in seven eastern states. Dinotefuran is a member of the neonicotinoid family of systemic pesticides that is known to be highly toxic to bees and associated with Colony Collapse Disorder. The states of Delaware, Maryland, New Jersey, North Carolina, Pennsylvania, Virginia, and West Virginia had previously asked EPA for emergency approval of the pesticide due to a ballooning stink bug population. The short term emergency measure became effective June 24 and will expire on October 15 of this year. Dinotefuran is already approved by EPA for use on other crops, such as grapes, cotton, and some vegetables. The emergency approval relates to the pesticide’s use on orchard crops such as apples, pears, peaches, and nectarines, for which it has not previously been allowed. Growers of those crops will now be able to apply dinotefuran from the ground twice per season. The agency will allow a total of 29,000 orchard acres to be treated, which does not include applications to the previously approved crops. Under a controversial stipulation known as a Section […]

(Beyond Pesticides, June 13, 2011) A new report released early last week shows that industry regulators have known for a long time that glyphosate, the active ingredient in the world’s best selling herbicide, RoundUp, causes birth defects. The report, “RoundUp and Birth Defects: Is the public being kept in the dark?” published by Earth Open Source, says that regulators misled the public about the safety of glyphosate for over 20 years. According to the report, the German government has known since 1998 and the EU Commission’s expert scientific review panel has known since 1999 that glyphosate causes malformations. As recently as last year, however, the German Federal Office for Consumer Protection and Food Safety told the Commission that there was no evidence of glyphosate causing birth defects. Meanwhile, these actions by industry and regualtors that have kept the public in the dark, the authors point out, has seriously endangered public health. Considering that Monsanto, as well as other producers of genetically engineered (GE) seeds are now pushing for glyphosate-tolerant crop approval in Europe, this is particularly disconcerting. If the Commission grants the approval as the U.S. Department of Agriculture (USDA) had done for GE alfalfa and sugar beets in the […]

(Beyond Pesticides, June 10, 2011) A report released jointly by the U.S. Department of Agriculture’s (USDA) Agricultural Research Service (ARS) and the Apiary Inspectors of America (AIA) shows that losses of honeybee populations over the 2010/2011 winter remained abnormally high, reflecting continuing damages attributed to colony collapse disorder (CCD). CCD, linked to a range of factors and agricultural chemicals, including systemic pesticides, has devastated bees and beekeepers around the country in recent years. According to the survey, 30% of managed honeybee colonies across the country were lost over the winter. Over the past five years, since the discovery of CCD, annual winter colony losses have hovered near the 30% mark. Similar loss percentages for the previous four years reflect this trend: 34% for the 2009/2010 winter, 29% for 2008/2009, 36% for 2007/2008, and 32% for 2006/2007. ARS entomologist Jeffrey Pettis, PhD, who helped to conduct the survey and has been the agency’s lead researcher on CCD heading up the USDA Bee Research Laboratory, said, “The lack of increase in losses is marginally encouraging in the sense that the problem does not appear to be getting worse for honey bees and beekeepers. But continued losses of this size put tremendous pressure […]

(Beyond Pesticides, June 3, 2011) According to the 2010 Agricultural Chemical Use Report released last week by the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS), use of the herbicide glyphosate, associated with genetically engineered (GE) crops, has dramatically increased over the last several years, while the use of other even more toxic chemicals such as atrazine has not declined. Contrary to common claims from chemical manufacturers and proponents of GE technology that the proliferation of herbicide tolerant GE crops would result in lower pesticide use rates, the data show that overall use of pesticides has remained relatively steady, while glyphosate use has skyrocketed to more than double the amount used just five years ago. The 2010 Agricultural Chemical Use Report shows that, in the states surveyed, 57 million pounds of glyphosate were applied last year on corn fields. Ten years prior, in 2000, this number was only 4.4 million pounds, and in 2005, it was still less than half of current numbers at 23 million pounds. Intense corn growing regions have experienced an even greater increase in glyphosate applications. Glyphosate use in the state of Nebraska increased by more than five times in just seven years, going […]

(Beyond Pesticides, April 20, 2011) Last Thursday, U.S. Senator Frank R. Lautenberg (D-NJ) introduced legislation to update and modernize the Toxic Substances Control Act of 1976 (TSCA) which has allowed tens of thousands of toxic substances onto the marketplace with little or no testing. The new ”˜Safe Chemicals Act of 2011,’ utilizing risk assessment methology, would, in theory, require chemical companies to prove their products are “safe” for human health and the environment when allowed in commerce. While creating priority reviews for the higher tisk categories of chemicals, many analysts are concerned that continued exclusive reliance on risk assessment with its serious uncertainties and lack of attention to least toxic alternatives allows unnecessary toxic chemical use and undermines a precautionary approach. Sen. Lautenberg, who chairs the Senate Subcommittee on Superfund, Toxics and Environmental Health, seeks to require that chemical manufacturers demonstrate the safety of industrial chemicals used in everyday household products. “The Safe Chemicals Act of 2011” would require safety testing of all industrial chemicals, and puts the burden on industry to prove that chemicals are safe in order to get on or stay on the market. Currently, EPA may not regulate a chemical unless it can first prove that […]

(Beyond Pesticides, April 1, 2011) A British government scientist on Wednesday announced that he has ordered a review of a class of pesticides known as neonicotinoids, to determine what effects they may have on bee and pollinator health. Neonicotinoids, such as clothianidin and imidacloprid, have come under intense scrutiny recently due to concerns regarding their toxicity to honeybees, which are essential for a secure food supply in their role as crop pollinators. This has led some to suggest that chemicals such as these could be contributors to honeybee Colony Collapse Disorder (CCD). According to the London Daily Mail, the chief scientist at the UK Department of Environment, Food and Rural Affairs (DEFRA), Professor Robert Watson, has directed DEFRA scientists to reexamine findings on neonicotinoids and their effects on bees. The Mail suggests that Watson may have been partly motivated by a recent study done by Dr. Jeffrey Pettis of the U.S. Department of Agriculture’s Agricultural Research Service. This study was the first to show that neonicotinoids impact the survival of bees at levels below the level of detection, meaning that field studies would not have considered the role of the pesticide, because they would not have detected it. Although a […]

(Beyond Pesticides, February 25, 2011) The U.S. Environmental Protection Agency (EPA) has released a new report detailing sales and usage of pesticides in the U.S. for the years 2006 and 2007 and showing a modest decrease in pesticide use. The report compiles data from EPA, the U.S. Department of Agriculture (USDA), and other sources in order to track pesticide trends and monitor usage. Previous industry use reports had been published every two years between 1994 and 2001; however, the last report was published ten years ago, in 2001, leaving a gap in the data. In one of the more promising findings, the report shows that pesticide use in the country did decrease throughout most of the last decade. Use of conventional pesticides, measured in pounds applied, decreased about 3% from 2002 to 2007 and 11% from 1997 to 2007. However, the total pounds of pesticide use decreased only by approximately 8% — from 1.2 to 1.1 billion pounds — during the years from 2000 to 2007. While any decrease in the use of toxic chemicals is a hopeful sign, this marginal reduction does not go far enough. The fact that chemicals which are known to adversely affect human health and […]

(Beyond Pesticides, February 23, 2011) In response to a request by beekeepers and environmentalists to remove a pesticide linked to Colony Collapse Disorder (CCD), the U.S. Environmental Protection Agency (EPA) in a letter, defended the pesticide clothianidin and the scientific study in question which was identified by beekeepers as a critically flawed study. EPA states that it does not intend to suspend or cancel clothianidin, even though independent studies have linked this chemical and others in its class to bee decline. Beyond Pesticides, as a part of a group of environmentalists and beekeepers, broke the news last December that a core study underpinning the registration of the insecticide clothianidin was unsound, citing leaked EPA memos which discloses the critically flawed scientific study and its reclassification as a “core” study on which clothianidin’s conditional registration was contingent on, to a “supplemental” study. Bayer CropSceicne, manufacturer of clothianidin designed and submitted to study to EPA as part of clothianidin’s registration requirement. Beekeepers claim that the initial field study guidelines, which the Bayer study failed to satisfy, were insufficiently rigorous to test whether or not clothianidin contributes to CCD in a real-world scenario: the field test evaluated the wrong crop, over an insufficient […]

(Beyond Pesticides, January 25, 2011) Research by the U.S. Department of Agriculture’s (USDA) Bee Research Laboratory and Penn State University shows that the neonicotinoid insecticide imidacloprid contribute —at extremely low levels— to bee deaths and possibly colony collapse disorder (CCD), the widespread disappearance of honey bees that has killed off more than a third of commercial honey bees in the U.S. While the study has not been published yet, the UK’s The Independent newspaper reports that honeybees exposed to imidacloprid are more susceptible to the fungal pathogen Nosema. This is the first study to show that neonicotinoids impact the survival of bees at levels below the level of detection, meaning that field studies would not have considered the role of the pesticide, because they would not have detected it. USDA researcher Jeffrey Pettis, PhD and Penn State University researcher Dennis Van Engelsdorp, PhD explained their research in the 2010 documentary, The Strange Disappearance of the Honeybees (transcript courtesy of Grist.org): [Pettis] I’ve done a recent study actually in collaboration with Dennis van Engelsdorp and some other researchers, where we exposed whole colonies to very low levels of neo-nicotinoids in this case, and then ”˜challenged’ bees from those colonies, with Nosema […]

(Beyond Pesticides, December 9, 2010) Beekeepers and environmentalists called on the U.S. Environmental Protection Agency (EPA) December 8, to remove a pesticide linked to Colony Collapse Disorder (CCD), citing a leaked EPA memo that discloses a critically flawed scientific support study. The November 2nd memo identifies a core study underpinning the registration of the insecticide clothianidin as unsound after EPA quietly re-evaluated the pesticide just as it was getting ready to allow a further expansion of its use. Clothianidin (product name “Poncho”) has been widely used as a seed treatment on many of the country’s major crops for eight growing seasons under a “conditional registration” granted while EPA waited for Bayer Crop Science, the pesticide’s maker, to conduct a field study assessing the insecticide’s threat to bee colony health. Bayer’s field study was the contingency on which clothianidin’s conditional registration was granted in 2003. As such, the groups are calling for an immediate stop-use order on the pesticide while the science is redone, and redesigned in partnership with practicing beekeepers. They claim that the initial field study guidelines, which the Bayer study failed to satisfy, were insufficiently rigorous to test whether or not clothianidin contributes to CCD in a real-world […]

(Beyond Pesticides, November 22, 2010) The British Beekeepers’ Association (BBKA) last week announced plans to end its controversial practice of endorsing pesticides for financial benefit from leading chemical manufacturers. The endorsement of four products as “bee-friendly” caused outrage among many beekeepers because one of the companies, Bayer Crop Science, makes pesticides like imidacloprid, an insecticide widely implicated in the deaths of honeybees worldwide. The 135-year-old charity endorsed pesticides used to combat the varroa mite that is linked to the collapse of colonies as “bee-friendly.” In return, for the past 12 years the association has received £17,500 ($27,949) a year from Bayer Crop Sciences and Syngenta. This relationship angered many members and some left the association. However, the BBKA denies that it has bowed to pressure from members who have been increasingly critical of its relationship with Bayer and other chemical companies. In a statement sent out this week to the secretaries of local beekeeping associations across the UK, the BBKA’s president, Martin Smith, said: “Following discussion with the companies involved, the BBKA trustees have decided that endorsement and related product-specific payments will cease as soon as practically possible.” He added: “The four products subject to BBKA endorsement are of declining […]

(Beyond Pesticides, November 5, 2010) At its October 2010 meeting, the U.S. Department of Agriculture’s (USDA) National Organic Standards Board (NOSB) passed a recommendation directing the USDA National Organic Program to prohibit engineered nanomaterials from certified organic products as expeditiously as possible. The NOSB, the expert citizen advisory panel set up by Congress to advise the USDA on organic policy, reviews materials and provides recommendations to the NOP on what should be allowed and prohibited in organic agriculture and processing, as materials and methods change over time. Organic advocates, members of the organic industry and the NOSB are concerned that engineered nanomaterials could contaminate organic food and fibers. Nanotechnology is the science and manipulation of chemical and biological materials with dimensions in the range from 1-300 nanometers (according to the NOSB recommendation). Because nanotechnology is such a new field, nanomaterials were not specifically addressed when the Organic Foods Production Act was passed in 1990. While synthetic materials are already prohibited from organic production, unless specifically exempted, the NOSB recommendation will pressure the NOP to block petitions seeking an exemption and keep nanomaterials out of food packaging and contact surfaces. The recommendation also provides clarification that nanosized particles of synthetic substances […]

(Beyond Pesticides, August 20, 2010) Behind closed doors this past Monday, the U.S. Environmental Protection Agency (EPA) and Bayer CropScience reached an agreement on a set of measures to gradually reduce and ultimately ban fully the use of the insecticde aldicarb in the U.S. This decision arrives on the heels of a revised risk assessment in which EPA found that babies and children under the age of five can ingest levels of the insecticide through food and drinking water at levels that exceed limits that the agency finds safe, and 25 years after 2,000 people fell ill after eating watermelons that were tainted with the pesticide. Though Beyond Pesticides applauds any decision to remove toxic chemicals from the environment, the problem with this cancellation, as with virtually all voluntary cancellations, is that the chemical can be legally used for years —eight years in this case — leaving open the opportunity for continued human and environmental exposure and harm. The decision was reached after EPA completed a revised risk assessment indicating that the pesticide does not meet the agency’s food safety standards. EPA scrutinized recent food consumption data from USDA to complete the risk assessment, which considered the percent of the […]

(Beyond Pesticides, August 5, 2010) A 400-year old large old grape vine considered to be the nation’s oldest in Manteo, North Carolina and known lovingly as “Mother Vine,” is slowly recovering from a powerful dose of herbicide sprayed by a utility company. The Virginia-based Dominion Power Company contracted Lewis Tree Service to spray power poles along the roads in the Manteo in May. The herbicide they used, Garlon3A, was accidentally sprayed on a tiny shoot from the vine that had grown a few feet up a pole on 84-year old Jack Wilson’s property. Unaware of the recent herbicide spraying by the utility power company, he noticed various brown, dead sections that began to appear in the plant in May. Not only did the vine suffer, but about 10 feet of a nearby hedge died, along with three limbs of a large pecan tree that had to be trimmed. The active ingredient in Garlon 3A, a Dow Chemical product, is triclopyr. It is a systemic herbicide which means that the poison spreads from the ends of the vine back toward the root. As a broadleaf weed killer, triclopyr is frequently used along rights-of-way and on industrial sites. In laboratory tests, triclopyr […]

(Beyond Pesticides, September 2, 2009) At least 40 small birds were found dead on Sunday in Quebec City, Canada, in what residents described as a scene out of a “Hitchcock movie.” A bird feeder, stuffed with 4-aminopyridine laced corn was the culprit. The chemical was set out on the roof of a building in effort to ward off nuisance pigeons; dozens of other birds were accidentally killed, particularly bronzed grackles. While Quebec City police purport that this pesticide is legal and no charges will be made, the Quebec Environment Ministry is investigating the incident to see if exterminators followed the proper guidelines. “The wrong type of bird ended up being targeted,” Quebec City police spokeswoman Catherine Viel said. A similar event happened in Schenectady New York in 2006, when Rentokill, Inc., a local exterminator applied 4-aminopyridine in order to ward off pigeons from a hospital. This caused a “deadly rain” of pigeons to fall from the sky, closing the hospital emergency room. One of the most prominent avicides, Avitrol –the trade name for 4-aminopyridine–i s available as grain baits or powder concentrate. It repels birds by poisoning a few members of a flock, causing them to become agitated, which signals […]

(Beyond Pesticides, April 30, 2009) On April 20, the National Marine Fisheries Service (NMFS) released a Biological Opinion (BiOp) finding that three additional pesticides, carbaryl, carbofuran, and methomyl, harm salmon and steelhead protected under the Endangered Species Act (ESA). The BiOp prescribes measures necessary to keep these pesticides out of salmon waters in Washington, Oregon, California, and Idaho. It is the second such plan issued in the last six months under a court settlement with fishermen and conservationists, filed by the non-profit law firm Earthjustice. The previous BiOp identified three organophosphate insecticides: chlorpyrifos, diazinon, and malathion. “These pesticides are designed to kill insects on agricultural crops, but when they get into the water system, they also kill aquatic insects that salmon feed on.” said Angela Somma, who heads the NMFS endangered species division. Under the terms of settlement, the Environmental Protection Agency (EPA) must implement measures within a year-long timeframe to prevent further exposure of the pesticides to the water that cultivate these species. The measures recommended by NMFS include: a ban on application of the three pesticides in windy conditions and buffer zones near water resources and require that land applications must be at least 50-600 feet from the […]

(Beyond Pesticides, December 8, 2008) A new study by a National Institute for Occupational Safety and Health (NIOSH) researcher finds the pesticide poisoning incidence rate among U.S. agricultural workers is thirty-nine times higher than the incidence rate found in all other industries combined. The study, “Acute Pesticide Poisoning Among Agricultural Workers in the United Sates, 1998-2005,” published in the December issue of the American Journal of Industrial Medicine, is believed to be the first detailed multi-state assessment of acute pesticide poisonings among agricultural workers. From 1998 to 2005, a total of 3,271 cases of acute occupational pesticide-related illness/injury among agricultural workers were identified in ten states. According to EPA, the Worker Protection Standards are designed to reduce the risk of injury or illness to agricultural field workers resulting from exposure to pesticides. Although the WPS was expanded in 1995 and in 2005 EPA developed a new WPS How to Comply (HTC) Manual, the NIOSH findings indicate that agricultural workers continue to have an elevated risk for acute pesticide poisoning. Furthermore, female agricultural workers experienced nearly twice the risk of pesticide poisoning of male agricultural workers. The most common factors that contributed to pesticide exposure included off-target drift, early reentry into […]

(Beyond Pesticides, November 11, 2008) Researchers at the Duke University School of Medicine have linked organophosphate pesticides to the epidemics of obesity and type 2 diabetes. The researchers specifically link neonatal low-dose parathion exposure in rats to disruption of glucose and fat homeostasis. The study, “Exposure of Neonatal Rats to Parathion Elicits Sex-Selective Reprogramming of Metabolism and Alters the Response to a High-Fat Diet in Adulthood,” was published in the November 2008 issue of Environmental Health Perspectives. It follows research by the National Institutes of Health (NIH) that links pesticide exposure to type 2 diabetes using epidemiological data from the Agricultural Health Study. Although most studies of organophosphates focus on their neurotoxicity, there is increasing evidence that these agents may also have a lasting impact on metabolic function. According to authors, obesity and consequent type II diabetes are rising at epidemic rates in the U.S. and many other countries around the world. Two of three U.S. adults are now classified as overweight. There are epidemiologic links between pesticide exposure and diabetes, and the same subpopulations that have the highest rates of obesity””inner-city, low-socioeconomic-status, agricultural populations””are also those that have greater exposure to organophosphates and other pesticides. The researchers chose parathion […]

(Beyond Pesticides, August 28, 2008) The German Coalition Against Bayer Dangers has filed legal action in Germany against Bayer for its role in marketing insecticides that the coalition believes company officials knew were toxic to honey bees. The suit follows recent action by the Natural Resources Defense Council (NRDC) against the Environmental Protection Agency (EPA) to force the agency into compliance with its Freedom of Information Act request for scientific studies relating to clothianidin, one of the Bayer-manufactured pesticides tied to bee toxicity. In May, Germany suspended the approval of eight pesticides linked to a massive bee die-off. Six of the eight suspended are manufactured by Bayer, the other two by Syngenta. Two of the primary active ingredients of concern are clothianidin and imidacloprid, both in the neonicotinoid family of chemicals. They are systemic pesticides, meaning the chemical is incorporated into plant tissue and can therefore be present in pollen and nectar, which is of particular importance to bees. They also have long persistence in the soil and can be absorbed by multiple generations of crops, increasing the likelihood of exposure for bees. Attorney Harro Schultze, who represents the Coalition Against Bayer Dangers said, “The public prosecutor [in Germany] needs […]
