(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, May 24, 2011) Last Friday, the U.S. Court of Appeals for the Ninth Circuit issued a summary order upholding a landmark legal decision requiring the U.S. Department of Agriculture (USDA) to conduct an Environmental Impact Statement (EIS) before approving the planting of genetically engineered (GE) crops. The decision upholds previous court rulings in favor of farmers and conservation advocates in a case on the future commercial uses of GE sugar beets, engineered to be resistant to Monsanto’s Roundup herbicide. “Today’s order cements a critical legal benchmark in the battle for meaningful oversight of biotech crops and food,” said Center for Food Safety (CFS) attorney George Kimbrell. “Because of this case, there will be public disclosure and debate on the harmful impacts of these pesticide-promoting crops, as well as legal protections for farmers threatened by contamination.” CFS, Organic Seed Alliance, High Mowing Organic Seeds, and the Sierra Club, represented by CFS and Earthjustice, challenged the USDA approval in 2008. They argued that GE sugar beets would contaminate organic and non-GE farmers of related crops, such as table beets and chard, as well as increase pesticide impacts on the environment and worsen the current Roundup-resistant “superweeds” epidemic in U.S. agriculture.

(Beyond Pesticides, May 4, 2011) According to a U.S. Environmental Protection Agency (EPA) internal review of pesticide registrations under special circumstances, also known as “conditional registration,” the agency may reduce its use of this “imprecise” category, whilch allows widespread use of toxic chemicals not fully tested. Conditional registration of pesticides allows market entry for a product in the absence of certain data. Recent reports have found that certain conditionally registered pesticides known to be hazardous to pollinators were allowed to used by EPA without a full data set. In an April 25, 2011 post on its website, EPA provides details on its recently completed internal review on the use of conditional registration for pesticide products. The agency has come under scrutiny recently since it was revealed that the conditionally registered pesticide, clothianidin, did not at the time it allowed the pesticide to be widely used have pertinent field data required on honeybees, even though the pesticide is known to pose risks to these vulnerable pollinators. This data is still outstanding even though clothianidin continues to be used in the environment. Conditional registration is allowed under Section 3(c)(7) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), whilch allows pesticide registration […]

(Beyond Pesticides, April 14, 2011) Researchers at the University of South Florida have discovered that the most widely used fungicide in the U.S., chlorothalonil, is lethal to frogs even at low doses. Chemical pollution, according to the researchers, is considered the second greatest threat to aquatic and amphibious species in the U.S. Because many vital systems of amphibians are similar to those in humans, researchers believe that amphibians may be an underused model for studying the impacts of chemicals in the environment on human health and set out to quantify amphibian responses to chlorothalonil. The study, lead by Teagan McMahon, PhD, was published in Environmental Health Perspectives and opens the door for researchers to quantify the effects of the chemical on other species as well as other toxic pesticides on amphibian populations and human health. Researchers looked at Rana sphenocephala (Southern leopard frog) and Osteopilus septentrionalis (Cuban treefrog) in outdoor aquatic mesocosms (experimental water enclosures) with and without the expected environmental concentration as well as twice the amount of chlorothalonil. They also conducted two dose-response experiments on O. septentrionalis, Hyla squirella (squirrel treefrog), H. cinerea (green treefrogs), and R. sphenocephala, evaluating the effects of the fungicide on the stress hormone […]

(Beyond Pesticides, April 7, 2011) From protecting pollinators, managing bed bugs, banning genetic engineering to going organic in the food we eat and the way we manage our yards, parks and open spaces – these are just a few of the pressing health and environmental issues that will be addressed at Sustainable Community: Practical solutions for health and the environment, the 29th National Pesticide Forum, April 8-9 at the Colorado School of Public Health in Aurora, Colorado.

(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, March 25, 2011) From protecting pollinators and banning genetic engineering to going organic in the food we eat and the way we manage our yards, parks and open spaces – these are just a few of the issues that will be addressed at the 29th National Pesticide Forum, Sustainable Community: Practical solutions for health and the environment, April 8-9 at the Colorado School of Public Health in Denver (Aurora), Colorado.

(Beyond Pesticides, March 14, 2011) Scientists working for the United Nations (UN) reveal in a report published March 10, 2011 that the collapse of honeybee colonies is now a global phenomenon that could have devastating consequences. Declines in managed bee colonies, seen increasingly in Europe and the US in the past decade, are now being observed in China, Japan and Egypt according to the report, “Global Bee Colony Disorders and other Threats to Insect Pollinators,” from the United Nations Environment Programme (UNEP). In the UNEP report, leading honeybee experts in the world stress that the potentially disastrous decline in bees —which are a vital pollinating element in food production for the growing global population””is likely to continue unless humans profoundly change their ways from the use of insecticides to air pollution. “The way humanity manages or mismanages its nature-based assets, including pollinators, will in part define our collective future in the 21st century,” UNEP Executive Director Achim Steiner said. “The fact is that of the 100 crop species that provide 90 per cent of the world’s food, over 70 are pollinated by bees.” “Human beings have fabricated the illusion that in the 21st century they have the technological prowess to […]

(Beyond Pesticides, February 28, 2010) The European Union (EU) standing committee on Tuesday decided to allow a 0.1 percent contamination threshold for unauthorized Genetically Engineered (GE) products in animal feed imports that would change the bloc’s zero-tolerance attitude toward biotech food. The EU Commission and Parliament are expected to accept the rule by this summer. If the vote is allowed through by the European Parliament and Council, those shipments could contain GE seeds that are authorized in their home country but may not even have been tested in Europe. Greenpeace spokesperson Stefanie Hundsdorfer warned that the new rules are possibly the first of many concessions to come. “Setting a tolerance threshold, however low, is a sign that Europe is losing control over its own food production to please American exporters,” said Ms. Hundsdorfer. “The danger now is that EU countries come under pressure from the pro-GE lobby to also allow GE contamination in food products for direct human consumption.” According to industry, exporting states and the European Commission say the new concession is necessary to prevent supply disruptions, because the EU’s feed industry relies on imports for 80% of its needs, and the world’s largest suppliers””Argentina, the United States and […]

(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, February 15, 2011) What do an organic CEO, the lawyer leading the fight to ban GE alfalfa, a scientist who linked pesticide exposure to ADHD, and a beekeeper who exposed leaked EPA documents have in common? They will all be speaking at Sustainable Community: Practical solutions for health and the environment, the 29th National Pesticide Forum, April 8-9 at the Colorado School of Public Health in Denver (Aurora), Colorado. This national environmental conference will cover topics such as pesticides and health, pollinators, organic food and farming, genetically engineered crops, healthy communities, organic land care, non-toxic bed bug control, and more. The event is open to the public and registration starts at $35. Limited scholarships are available, contact Beyond Pesticides for information. Speaker highlights (see full list) Maria Rodale — author of Organic Manifesto, CEO of Rodale Inc. -publisher of Organic Gardening and Prevention magazines, and co-chair of the research-based Rodale Institute’s board of directors.

Theo Colborn, PhD — honored by Time magazine as a global Environmental Hero, Dr. Colborn is […]

(Beyond Pesticides, February 9, 2011) Last Friday the U.S. Department of Agriculture (USDA) announced plans to allow the U.S. sugar beet industry to continue growing Monsanto’s “Roundup Ready,” genetically engineered (GE) sugar beets, despite the incompletion of an environmental impact statement (EIS). This comes one week after USDA decided to fully deregulate GE alfalfa seed, despite the risks it poses to both organic and conventional farmers. On Monday, Center for Food Safety, Beyond Pesticides, Sierra Club and Cornucopia Institute formally filed a 60-day notice of intent to sue the agency concerning its decision to allow unrestricted deregulation of GE alfalfa. The 60-day notice of intent to sue, filed February 7, 2011, officially notifies USDA’s Animal and Plant Health Inspection Service (APHIS) of the groups’ intent to sue pursuant to the citizen suit provision of the Endangered Species Act (ESA), citing APHIS’ violation of Section 7 of the ESA in failing to ensure that the deregulation of GE alfalfa is not likely to jeopardize threatened or endangered species and their habitat. According to Section 7, APHIS must consult with the U.S. Fish and Wildlife Service (FWS) to ensure that agency actions do not impact threatened or endangered species. The notice charges […]

(Beyond Pesticides, February 1, 20011) On January 31, 2011, a coalition of organic companies and environmental organizations, including Beyond Pesticides, released an open letter and call to action on the U.S. Department of Agriculture’s (USDA) January 27 decision to deregulate “RoundUp Ready” (glyphosa te-tolerant) genetically engineered (GE) alfalfa, allowing its unrestricted cultivation and threatening organic and non-GE conventional farmers. It sets a precedent for future deregulation of GE crops. The letter encourages individuals to write to President Obama opposing the decision and asking that the administration reconsider its position. Other signatories include upcoming National Pesticide Forum keynote Maria Rodale (CEO, Rodale, Inc. and author of Organic Manifesto), National Organic Coalition, Center for Food Safety, Organic Trade Association, Organic Valley, Stonyfield Farm, and more. The decision to deregulate GE alfalfa follows USDA’s completion of the court-mandated environmental impact statement (EIS). Secretary of Agriculture Tom Vilsack called for “coexistence” among GE, organic and conventional non-GE farmers, despite the clear recognition in the EIS that GE contamination of organic and conventionally grown crops presents a huge problem. The EIS also fails to take into account the documented increase in herbicide-resistant “super weeds” that is requiring the use of highly toxic herbicide cocktails for […]

(Beyond Pesticides, January 28, 2011) Environmental and public interest groups are extremely disappointed with the announcement late Thursday that the U.S. Department of Agriculture (USDA) plans to fully deregulate genetically engineered (GE) alfalfa seed, despite the risks it poses to both organic and conventional farmers. Among those upset with the announcement are the cosponsors of the original Organic Foods Productions Act, Senator Patrick Leahy (D-Vt.) and Representative Peter DeFazio (D-OR), who have weighed in with their criticism of USDA’s decision. This decision follows the agency’s completion of the court-mandated environmental impact statement (EIS) for GE alfalfa. Secretary of Agriculture Tom Vilsack called for “coexistence” among GE, organic and conventional non-GE farmers, despite the clear recognition in the EIS that GE contamination of organic and conventionally grown crops presents a huge problem. The EIS also fails to take into account the documented increase in herbicide-resistant “super weeds” that is requiring the use of highly toxic herbicide cocktails for weed control on conventional farms. Likewise, USDA has not shown that contamination-free coexistence with deregulated GE alfalfa is likely or possible. “We’re disappointed with USDA’s decision and we will be back in court representing the interest of farmers, preservation of the environment, and […]

(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, January 21, 2011) Further proof of the ineffectiveness of chemical pest control has emerged in the form of a study from The Ohio State University documenting the growing resistance of bed bugs to pesticide treatments. The study shows that modern bed bugs have developed the ability to defend themselves against pyrethroid pesticides, due in part to the widespread use of such treatment methods. These findings highlight the need for widespread adoption of alternative, non-chemical methods for controlling bed bugs and other insect pests. The study, which was published in the journal PLoS ONE, is entitled “Transcriptomics of the Bed Bug (Cimex lectularius).” The researchers found that the bugs developed the ability to produce certain enzymes, which can break down toxic chemicals, at higher levels of than previous generations. These enzymes allow the chemicals to be easily excreted by the insects without being harmed. When comparing modern bugs to a colony that has existed in isolation for several decades — without any exposure to pesticides — the team found strong evidence of resistance. Bugs from the isolated colony were readily killed when exposed to even small amounts of pyrethroids. However, the modern bugs, which have been exposed to pesticide […]

(Beyond Pesticides, January 7, 2011) The Office of the Inspector General (OIG) for the U.S. Environmental Protection Agency (EPA) has released a report criticizing the agency’s lack of regulation concerning antimicrobial products. Citing a number of failures, the report finds that the EPA’s Antimicrobial Testing Program (ATP) has been largely inadequate in testing products to ensure safety and efficacy, and has failed to remove products that did not meet program standards. This report is especially of concern because some antimicrobials, such as triclosan, are known to cause dangerous public health and environmental hazards. Triclosan is one of the most prevalent antibacterial compounds found in products ranging from soaps and toothpastes to fabrics and toys. Studies have increasingly linked triclosan (and its chemical cousin triclocarban), to a range of adverse health and environmental effects, from skin irritation, allergy susceptibility, bacterial, endocrine disruption and compounded antibiotic resistant, tainted water, and dioxin contamination to destruction of fragile aquatic ecosystems. Through ATP, antimicrobial products including hospital disinfectants and tuberculocides are meant to be tested to ensure that they meet health standards and that the claims on the product labels are accurate. However, OIG has found that “EPA’s implementation of the ATP has not delivered […]

(Beyond Pesticides, January 3, 2011) The United Nations Food and Agriculture Organization (FAO) has announced the initial results of an experimental program in West Africa that reduces farmers’ use of pesticides and chemical inputs while increasing yields and income. The program, entitled the West African Regional Integrated Production and Pest Management Program, evaluated the use of ecological management versus conventional practices on vegetables, cotton, and grain crops in the countries of Benin, Burkina Faso, Mali, and Senegal. The evaluation shows dramatic decreases in pesticide usage, reduced environmental degradation, as well as increases in farmer income through higher yields and reduced inputs. According to the FAO (which previously advocated for organic agriculture), the goals of the program, which is ongoing, are “building local farming capacity, improving food security and livelihoods, and raising awareness of negative externalities and positive alternatives.” These are accomplished through training farmers in what the FAO calls integrated production and pest management (IPPM) methods so that they can reduce toxic inputs and pollution while enhancing soil fertility and retaining more of their income. The particular methods of IPPM include reducing pesticide usage, soil building through incorporation of compost and manure and the planting of cover crops, careful monitoring […]

(Beyond Pesticides, December 14, 2010) A petition of more than a million signatures was presented to the European Commission last week, demanding a halt to approvals of new genetically modified (GM) crops and the establishment of up a new scientific body to study the impact of the technology and determine regulations. Greenpeace led the effort. The petition is seen as a test case for the “European citizen’s initiative,” introduced under the European Union’s new constitutional treaty, which enables a million or more people to jointly ask the European Commission to change EU legislation. It follows the Commission’s decision in March to grant the first EU GM cultivation approval in 12 years for the “Amflora” potato. “Over a million people across Europe have set the EU a democratic test — will the EU address the real concern people have about GM crops and food, or will it side with the chemical industry lobbyists controlling GM technology?” Greenpeace’s EU Director Jorgo Riss said. “Until safety issues of GMs are examined by independent experts, all GM authorizations should stop.” A spokesman for the EU executive said it would treat the signatures “as a petition in the spirit of the citizen’s initiative,” Despite the […]

(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 […]
