(Beyond Pesticides, March 8, 2011) Leading up to the 29th National Pesticide Forum in Denver, Beyond Pesticides and the Denver Botanic Gardens will be hosting a free screening of the award-winning film Vanishing of the Bees on Wednesday, April 6th, 7:00pm at the Denver Botanic Gardens (1007 York Street). The film, which is narrated by Ellen Page, takes a piercing investigative look at the economic, political and ecological implications of the worldwide disappearance of the honeybee and empowers the audience to fight back. Join us for the film Wednesday evening, and then learn more about Colony Collapse Disorder at the National Pesticide Forum at the Colorado School of Public Health, Friday evening and Saturday, April 8-9. The film is free. Register for the conference online. Film Synopsis Honeybees have been mysteriously disappearing across the planet, literally vanishing from their hives. Known as Colony Collapse Disorder, this phenomenon has brought beekeepers to crisis in an industry responsible for producing apples, broccoli, watermelon, onions, cherries and a hundred other fruits and vegetables. Commercial honeybee operations pollinate crops that make up one out of every three bites of food on our tables. Vanishing of the Bees follows commercial beekeepers David Hackenberg and Dave […]

(Beyond Pesticides, March 1, 2011) As insect resistance to pesticides steadily increases, and the underlying conditions of poverty, poor water management, and indecent living conditions contribute to the spread of malaria, the search for silver bullet solutions escalates. Researchers are exploring genetic engineering as the next frontier for a product-based approach to fighting malaria, which annually kills nearly one million people worldwide. While releasing genetically engineered organisms into the environment raises serious concerns that must be fully studied, some in the public health community believe this could help slow the spread of malaria as part of an integrated campaign. At the same time, the long-term underlying causes that support the spread of malaria must be addressed. The new research indicates that a genetically engineered fungus carrying genes for a human anti-malarial antibody or a scorpion anti-malarial toxin could be an effective tool for combating malaria, at a time when the effectiveness of current pesticides against malaria mosquitoes is declining. The researchers also say that this general approach could be used for controlling other devastating insect and tick bug-borne diseases, such as or dengue fever and Lyme disease. “Though applied here to combat malaria, our transgenic fungal approach is a very […]

(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.

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

(Beyond Pesticides, February 14, 2011) The Oregon Department of Environmental Quality (DEQ) hosted a public hearing on February 10 on a proposal to give Oregon the nation’s strictest water quality standards. The proposal filed by the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) is currently tied in great measure to human consumption of fish. The change intends to improve water quality by changing the state’s assumption of how much fish people eat. Current rules describe for water clean enough to let each Oregon resident eat 6.5 grams of fish per day, however the new rule would raise that amount to 175 grams per day. According to The World Newspaper, N. Kathryn Brigham, secretary of the Confederated Tribes of the Umatilla Indian Reservation, said that members of her tribe consume 389 grams of fish per day, mostly salmon. The 175-gram proposal resulted from negotiations among the department, tribes, and industries. “The higher fish consumption rate is designed to better protect Oregon’s more sensitive fish consumers,” said Leo Steward, vice-chair of CTUIR board of trustees. “In the past, water quality standards did not protect Indian People. They did not protect our children, our women, our mothers. We must think of the […]

(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 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 20, 2011) Beyond Pesticides and the National Organic Coalition (NOC) are encouraging their members to contact President Obama and the U.S. Department of Agriculture (USDA) and tell them not to approve (or not deregulate) Monsanto’s “RoundUp Ready,” genetically engineered (GE) alfalfa, which contributes to genetic drift, superweeds, and the use of a hazardous herbicide glyphosate. In December, USDA completed its environmental impact statement (EIS) of GE alfalfa. Secretary of Agriculture Tom Vilsack has rejected the option to prohibit the planting (and continuing to regulate) GE Alfalfa, despite the clear recognition in the EIS that that GE contamination of organic and conventionally grown crops presents a huge problem. USDA released its 2,400 page EIS as required by a 2007 Federal District Court decision and upheld by both 2009 Ninth Circuit Court of Appeals and June 2010 U.S. Supreme Court rulings. The litigation was led by the Center for Food Safety, and joined by Beyond Pesticides, and other groups, including conventional and organic seed companies and producers. Three alternatives are considered during the preparation of the final EIS: 1) to maintain the RR alfalfa’s status as a regulated article; 2) to deregulate RR alfalfa; or 3) to deregulate RR […]

For over sixty-years, the Rodale Institute has been researching the best practices of organic agriculture and sharing their findings with farmers and scientists throughout the […]

(Beyond Pesticides, January, 11, 2011) Responding to a June 2006 petition submitted by Fluoride Action Network, Beyond Pesticides, and Environmental Working Group, the U.S. Environmental Protection Agency (EPA) has announced that it proposes to eliminate the use of the toxic fumigant sulfuryl fluoride in agriculture and food related applications. The agency plans to cancel all allowable pesticide residue levels (tolerances) for the chemical, finding that, when residues on food products are combined with fluoridated drinking water and toothpaste, public exposure levels are too high. Under the Federal Food, Drug, and Cosmetic Act (FFDCA), EPA is required to ensure that pesticides it has registered for use cannot combine with non-food sources of the same substance to result in unsafe levels of exposure for that chemical. According to EPA officials, the decision appears to be the first time the agency has granted substantive formal objections to a pesticide tolerance rule based on public health advocates’ evidence that a particular chemical’s use violates the safety standard for aggregate exposures under federal law. Despite granting the petition’s assertion that total public exposure to fluoride is too high, EPA has denied the petition’s request for an immediate stay of all registered uses of sulfuryl fluoride.

(Beyond Pesticides, January 5, 2011) Your voice is critical in generating public comments on a petition, published in the Federal Register, to ban the antibacterial chemical triclosan. As you may know, this chemical, now found in the bodies of 75% of the U.S. population, is linked to endocrine disruption, bacterial and antibiotic resistance, dioxin contamination, and contaminated fish and biosolids. We have five more weeks —until February 7, 2011— to let EPA know that triclosan must be banned to protect the public, workers and the environment. Click here for the document you can use to publicize the public comment period on Ban Triclosan petition or email info@beyondpesticides for the word version. EPA published in the Federal Register a petition, filed by 82 public health and environmental groups, to ban the hazardous antimicrobial/antibacterial pesticide triclosan for non-medical use. The chemical is found in products from clothing to soaps. The Federal Register notice (Petition for a Ban on Triclosan, 75 FR 76461, December 8, 2010) announces a public comment period until February 7, 2011 on the need to ban triclosan under numerous federal statutes from pesticides, clean water, safe drinking water, to endangered species. SUGGESTED ACTION AND SAMPLE PUBLIC COMMENT: Please send […]

(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 17, 2010) Secretary of Agriculture Tom Vilsack disappointed organic farmers and consumers, as well as environmentalists when he announced December 16, 2010 that the U.S. Department of Agriculture was considering “deregulating” a genetically engineered crop that is tied to genetic drift, superweeds, and the use of a hazardous pesticide -Monsanto’s genetically-engineered (GE) Roundup (glyphosate) Ready (RR) alfalfa. The Department released a 2,400 page Environmental Impact Statement (EIS) as required by a 2007 Federal District Court decision and upheld by both 2009 Ninth Circuit Court of Appeals and June 2010 U.S. Supreme Court rulings. The litigation was led by the Center for Food Safety, and joined by Beyond Pesticides, and other groups, including organic seed companies and producers. A broad coalition of groups has previously called for USDA to deny approval of Monsanto’s genetically engineered, Roundup Ready alfalfa (GE alfalfa). In March, more than 200,000 people submitted comments to USDA critiquing the substance and conclusions of its Draft EIS on GE Alfalfa. In addition, more than 300 public interest organizations, farmers, dairies, retailers and organic food producers from the U.S. and Canada delivered a critical letter to USDA. U.S. Senator Patrick Leahy (D-Vt.) and Rep. Peter DeFazio (D-OR), […]

(Beyond Pesticides, December 10, 2010) Announcing a 60-day public comment period, the U.S. Environmental Protection Agency (EPA) yesterday published in the Federal Register a petition filed by 82 public health and environmental groups, led by Beyond Pesticides and Food and Water Watch, to ban the controversial antimicrobial/antibacterial pesticide triclosan, found in products from clothing to soaps, for non-medical use. The Federal Register notice (Petition for a Ban on Triclosan, 75 FR 76461, December 8, 2010) invites the public to comment until February 7, 2011 on the need to ban triclosan under numerous federal statutes. The petition, filed on January 14, 2010, identifies pervasive and widespread use of triclosan and a failure of EPA to: (i) address the impacts posed by triclosan’s degradation products on human health and the environment, (ii) conduct separate assessment for triclosan residues in contaminated drinking water and food, and (iii) evaluate concerns related to antibacterial resistance and endocrine disruption. The petition cites violations of numerous environmental statutes, including laws on pesticide registration, the Clean Water Act, Safe Drinking Water Act, and Endangered Species Act. It also documents that triclosan is no more effective than regular soap and water in removing germs and therefore creates an unnecessary […]

(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, December 3, 2010) Ignoring the assessments of top U.S. scientists and its own Scientific Review Committee, the California Department of Pesticide Regulation (DPR) announced its approval on December 1, 2010 for use of methyl iodide, a potent carcinogen and water contaminant, as a fumigant in the state’s strawberry fields, nut orchards, and flower farms. The news comes one day after press events in eight California cities urging DPR to deny its approval, and after Washington State decided to not allow use of the chemical.”¨ Methyl iodide poses great risk to farmworkers and those who live near fields where it will be applied as well as to air and waterways, should it escape into the surrounding environment. It is on California’s official list of known carcinogenic chemicals and has been linked to serious risks in reproductive and neurological health. A coalition of farmworker, farm, public health and environmental groups is calling on the administration of governor-elect Jerry Brown to work with his agency staff to undo this approval, and deny the use of methyl iodide in California. Specifically, the groups call on Brown to: ”¢ Follow the recommendation of John Froines, PhD, Chair of the Scientific Review Committee, to […]

(Beyond Pesticides, December 1, 2010) Several fishing and environmental conservation groups are suing the U.S. Environmental Protection Agency (EPA) for failing to limit the use of six agricultural pesticides to protect salmon. Restrictions on the use of six pesticides in Oregon, Washington and California shown to harm endangered salmon and steelhead, were ordered after a court found that EPA violated the Endangered Species Act (ESA) by failing to restrict the pesticides from entering salmon habitat. However EPA has failed to act to restrict the pesticides. The lawsuit, filed in U.S. District Court in Washington is the fourth lawsuit the plainstiffs -Northwest Coalition for Alternatives to Pesticides, Pacific Coast Federation of Fishermen’s Associations; Institute for Fisheries Resources and Defenders of Wildlife- brought against the EPA to restrict the pesticides diazinon, malathion, chlorpyrifos, carbaryl, carbofuran and methomyl in streams of endangered salmon and steelhead. The plaintiffs seek a judgment declaring that EPA’s failure to implement the organophosphate (OP) and carbamate biological opinions issued by the National Marine Fisheries Service (NMFS) violates the ESA, and a judgment declaring that EPA is taking listed salmonids in violation of the ESA. The lawsuit seeks an order vacating and enjoining EPA’s authorization of the uses of […]

(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 9, 2010) In October, 11 groups representing chemical-intensive and biotech-based agricultural interests dropped out of the process to develop an American National Standards Institution (ANSI)-certified standard for sustainable agriculture, facilitated by the Leonardo Academy. The groups cited committee dominance “by environmental groups, certification consultants, agro-ecology and organic farming proponents” and an opposition to “modern agriculture” as their main reasons for resigning. The drop-outs include the American Farm Bureau Federation, American Frozen Food Institute, American Soybean Association, California Seed Association, CropLife America, Environmental Intelligence, Inc., Grocery Manufacturers Association, National Corn Growers Association, National Cotton Council of America, and United Fresh Produce Association. “These groups relentlessly pushed for molding the standard to validate industrial agriculture and high tech genetic manipulation,” says Jeff Moyer, Farm Director at the Rodale Institute and active member of the committee. “The model they propose confuses short-term profits for sustainability.” Responding to the resignation, a Leonardo Academy spokesperson said it, “recognizes their perspective but disagrees with their assessment.” The Academy believes their ANSI-approved standard development process provides the balance across interest categories needed for developing a Sustainable Agriculture Standard that will be widely implemented and successful in the marketplace. They state that the balance is […]

(Beyond Pesticides, November 8, 2010) After numerous scandals involving China’s industrialized food supply, a new movement is afoot in the world’s most populous nation toward local, organic, and sustainable food. According to a promising Washington Post report, “Young Chinese farmers sowing seeds for organic revolution,” many of the organic farmers working to meet the growing demand are urban professionals seeking an escape from fast paced city life. The overuse of pesticides in industrialized agriculture has created numerous problems for people and the environment. Pesticide use has been linked to many diseases including numerous types of cancer, Parkinson’s, and learning disabilities. In addition pesticides are also dangerous to wildlife. Pesticides often kill non-target organisms that may be beneficial to farmers, such as predatory insects. Organic agriculture is an ecological approach to farming that does not rely on or permit toxic pesticides, chemical fertilizers, genetically modified organisms, antibiotics, sewage sludge, or irradiation. Instead of using these harmful products and practices, organic agriculture utilizes techniques such as cover cropping, crop rotation, and composting to produce healthy soil, prevent pest and disease problems, and grow healthy food and fiber. Just as in the United States, demand for local and organic food is growing in […]

(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, November 4, 2010) A new study finds that organically grown onions, carrots, and potatoes generally have no higher levels of antioxidants and related substances than vegetables grown with traditional fertilizers and pesticides, disputing other studies and failing to examine pesticide residues or other essential vitamin content. The study also does not consider the environmental and health impacts of conventional, chemical-based production systems. Researchers analyzed antioxidants termed “polyphenols” from onions, carrots and potatoes grown using conventional and organic methods and found no differences in polyphenol content for organic vs. traditional methods of growth. The study, “Effects of Organic and Conventional Growth Systems on the Content of Flavonoids in Onions and Phenolic Acids in Carrots and Potatoes” was published in the American Chemical Society’s bi-weekly Journal of Agricultural and Food Chemistry. In this study, onions, carrots, and potatoes were cultivated in two-year field trials in three different geographical locations, comprising one conventional and two organic agricultural systems. The contents of two kinds of polyphenols, flavonoids and phenolic acids in plants were analyzed by pressurized liquid extraction and high-performance liquid chromatography−ultraviolet quantification. Polyphenols have one or more phenol units in their chemical structure and are a group of secondary plant metabolites. […]

(Beyond Pesticides, November 2, 2010) A new study published in the American Chemical Society’s bi-weekly journal Industrial & Engineering Chemistry Research shows that nicotine could be used as an effective natural pesticide on a large scale, however the article fails to discuss the health and environmental hazards of tobacco production. Conventional tobacco production is heavily reliant on pesticides and synthetic fertilizers, and nicotine poisoning, called green tobacco sickness, is common among farmworkers in tobacco fields. The new study, “Experimental Investigations into the Insecticidal, Fungicidal, and Bactericidal Properties of Pyrolysis Bio-oil from Tobacco Leaves Using a Fluidized Bed Pilot Plant,” was published online September 14, 2010. According to lead researcher Cedric Briens, PhD from the University of Western Ontario, concerns about the health risks of tobacco have reduced demand and hurt tobacco farmers in some parts of the world. Scientists are looking for new uses for tobacco. One potential use is as a natural pesticide, due to tobacco’s content of toxic nicotine. For centuries, gardeners have used home-made mixtures of tobacco and water as a natural pesticide to kill insect pests. A “green” pesticide industry based on tobacco could provide additional income for farmers, and as well as a new eco-friendly […]
