(Beyond Pesticides, June 20, 2012) To control a growing insect resistance problem to the widely used biological pesticide Bacillus thuringiensis (Bt) toxin, now genetically engineered into corn, two experts have concluded that the U.S. Environmental Protection Agency (EPA) should double the so-called “refuges” of acreage planted with non-genetically engineered (GE) corn. If the resistance problem continues -exacerbated by these GE pesticide incorporated plants (PIPs), it will eliminate a bio-rational tool often used by organic farmers. The article, “Delaying Corn Rootworm Resistance to Bt Corn,” was published in the June 2012 issue of Journal of Economic Entomology. Currently, EPA requires 20 percent of the total acreage to be set aside for refuges for corn producing one Bt protein (CryBb1), and a 5 percent refuge portion for corn that produces two different Bt proteins at the same time. However, earlier this year, inspections found that more than 40% of American farmers who planted certain varieties of the GE corn in 2011 failed inspections to verify compliance with these management practices to prevent insect resistance. “Most of the corn seed currently produced in the U.S. is transgenic and includes genes for insect control,” said co-author Fred Gould, PhD. “Enlarging refuges will require more […]

(Beyond Pesticides, June 19, 2012) A senior U.S. Environmental Protection Agency (EPA) official stated recently that the agency is prepared to exercise is long-neglected authority under the Toxic Substances Control Act (TSCA) to ban or restrict hazardous chemicals. In reference to TSCA, EPA Acting Assistant Administrator for Chemical Safety and Pollution Prevention Jim Jones was quoted as saying that, “We will try and exercise some muscle we have not exercised for decades.” In fact, EPA has not sought to use this authority under TSCA since 1991, when the U.S. Court of Appeals for the Fifth Circuit overturned the agency’s attempt to ban asbestos. Speaking on June 7 to a forum convened by The Environmental Council of the States, Mr. Jones was further quoted as expecting a decision from EPA on the matter “in the near future.” Section 6 of TSCA requires that EPA prove it has substantial evidence that a chemical poses an unreasonable risk before it can ban, restrict, or take other actions to manage that risk. In his comments, Mr. Jones cited EPA’s March 1 announcement that it had selected 83 chemicals or groups of chemicals for risk assessment in the near future. EPA’s work plan identified seven […]

(Beyond Pesticides, June 18, 2012) Once again, attempts to repeal the Clean Water Act permits for pesticide discharges are underway in Congress. This week the 2012 Farm Bill will be introduced to the Senate floor where measures to attack environmental laws have been added unceremoniously to the bill, including the controversial H.R. 872, Reducing Regulatory Burdens Act, which seeks to undermine federal authority to monitor our nation’s waterways for pesticide contamination, as well as eroding already lax federal oversight of genetically engineered crops. Congress is working on the monumental process of altering and renewing the Farm Bill, S. 3240. This process only comes along every five years and has major impacts on how we grow our food. The last Farm Bill was passed in 2008, and expires in 2012. The bill is expected to be introduced on Senate floor on Tuesday, June 19. North Carolina Democratic Senator Kay Hagan and Idaho Republican Senator Mike Crapo have introduced an amendment (amendment 2367, full text available in the Congressional Record) to the Farm Bill that states pesticides should be allowed into water bodies without any oversight, leaving the public to swim, fish and boat on waters that are contaminated with endocrine disruptors, […]

(Beyond Pesticides, June 15, 2012) Researchers at the Duke University School of Medicine have developed a laboratory screening system for detecting neurotoxic chemicals and successfully tested it on more than 1,400 potential toxicants. The study confirms the high toxic activity of the chemical piperonyl butoxide (PBO), a chemical “synergist” used to increase the potency of more than 700 insecticides, including synthetic pyrethroids widely used in mosquito and community spray programs and for home use. The study, entitled “The Insecticide Synergist Piperonyl Butoxide Inhibits Hedgehog Signaling: Assessing Chemical Risks,” was published in the May 2012 edition of the journal Toxicological Sciences. The testing shows that PBO disrupts a biological signaling system that is “critical in neurological development,” the researchers reported in the abstract of their paper. The study finds that the disruption of this critical pathway “may be the molecular basis for profound developmental defects in children exposed in utero to PBO.” Piperonyl butoxide is not itself classified as a pesticide, but companies combine it with insecticides to increase their potency. PBO came into widespread use when the U.S. Environmental Protection Agency (EPA) phased out chlorpyrifos and other organophosphate pesticides nearly a decade ago after determining that they posed a risk […]

(Beyond Pesticides, June 14, 2012) Across the U.S., some communities are responding to the threat of mosquito-transmitted West Nile virus (WNv) with aerial insecticide spray programs. This method of mosquito management is widely considered by experts to be both ineffective and harmful due to the hazards associated with widespread pesticide exposure. Given the lack of evidence that adulticides (insecticides that target adult mosquitoes) reduce or prevent mosquito-borne incidents or illnesses, public health and environmental advocates question the decision to resort to indiscriminate spraying. Studies have shown that aerial spraying for adult mosquitoes is greatly ineffective (as little as 1% of mosquitoes will be hit, according to Cornell University entomologist David Pimentel). Pesticides like those typically used in aerial sprayings against mosquitoes, including synthetic pyrethroids and organophosphates, have been linked to numerous adverse health effects including asthma and respiratory problems, dermatological reactions, endocrine disruption, chemical sensitivities, and cancer. These chemicals can also be harmful or fatal to non-target wildlife, including pollinators like the honeybee. Further, pesticides that kill mosquitoes also kill their predators, leading to fewer biological checks on mosquito populations than without spraying. Here are some of the areas currently, or soon to be spraying insecticides intended to kill adult […]

(Beyond Pesticides, June 12, 2012) Congressman Edward J. Markey (D-Mass.), senior member of the Energy and Commerce Committee, has asked the U.S. the Food and Drug Administration (FDA) to halt the use of the insecticide lindane in pharmaceutical treatments for head lice in children. Despite research on its toxicity and ineffectiveness, FDA continues to allow lindane to be used in prescription shampoos and lotions to treat cases of lice and scabies, overwhelmingly on children. Rep. Markey’s letter to the FDA can be found here. Lindane has been found to cause skin irritation, seizures, and, in rare instances, even death. Infants and children are especially sensitive to the health risks posed by pesticides such as lindane because of their developing bodies. In 2005, the U.S. Department of Health and Human Services determined that lindane could cause cancer in humans, and the EPA cancelled all pesticide registrations for agricultural uses of lindane in 2006 because of its toxicity to humans and persistence in the environment. It was banned in California in 2000 because of high levels of water contamination. Following the ban, water contamination drastically declined, and an increase in head lice cases was not reported. A 2002 study that compared efficacy […]

(Beyond Pesticides, June 12, 2012) Monsanto’s new drought tolerant corn, DroughtGard, reduces crop losses only modestly during moderate droughts, and will not reduce the crop’s water requirements, according to a report released by the Union of Concerned Scientists (UCS). The report finds that traditional breeding and improved farming practices have done more to increase drought tolerance, and that further improvements in genetic engineering are unlikely to solve the drought problem in coming years. Monsanto’s advertising campaigns touted its intention to develop seeds that yield “more crop per drop,” but there is no evidence that DroughtGard will help the crops or farmers use water more efficiently. The report, High and Dry: Why Genetic Engineering is Not Solving Agriculture’s Drought Problem in a Thirsty World, finds that during limited testing DroughtGard ””the only crop genetically engineered (GE) for drought tolerance approved for commercial use, containing the engineered gene cspB”” reduced crop losses by about six percent. U.S. Department of Agriculture (USDA) analysis of data supplied by Monsanto show that DroughtGard produces only modest results, and only under moderate drought conditions. The report estimates that DroughtGard does not improve water use efficiency. By comparison, breeding and improved farming practices have increased drought tolerance […]

(Beyond Pesticides, June 11, 2012) More than one year after petitioning the U.S. Food and Drug Administration (FDA) to complete a mandatory environmental impact statement on the first-ever genetically engineered (GE) fish intended for human consumption, Earthjustice has submitted a letter on behalf of its co-petitioners urging the agency to meet its obligation promptly. The letter points out that FDA is prohibited from acting on the application to raise and release into commerce genetically engineered salmon until the agency has completed a comprehensive environmental risk assessment on the fish. Earthjustice filed the petition on May 25, 2011 along with Ocean Conservancy, Friends of the Earth, Center for Food Safety, Food & Water Watch, the Center for International Environmental Law, and Greenpeace. In addition to reminding FDA of its obligation to complete the risk assessment, the petitioners also ask the agency to improve its process for reviewing these kinds of applications to commercialize GE animals to address environmental threats and public concerns at a much earlier stage. FDA has held off on taking decisive action on the application from Massachusetts-based AquaBounty Technologies, which has been seeking approval to sell its GE salmon product in the U.S. for more than a decade.

(Beyond Pesticides, June 8, 2012) The U.S. Department of Agriculture’s (USDA) National Organic Program (NOP) has published a final rule in the Federal Register officially codifying into federal regulations changes to organic standards that were recommended by the National Organic Standards Board (NOSB) over the past year and a half. The changes to the National List of Allowed and Prohibited Substances (National List) include the renewal of a number of substances already on the list, the removal of two substances, and specific changes to several others. Among the more notable changes to the organic standards made by the publication of this final rule is a hard fought victory for organic hops growers in the form of a new requirement that, beginning the first day of 2013, all hops used in organic beer production must be produced organically. Due to the “commercial availability” clause in the organic law, beer bearing the organic seal had previously been allowed to contain conventionally produced hops due to a perception that hops produced organically were not available in the necessary quantities. However, the American Organic Hop Grower Association petitioned the NOSB to remove this allowance on the basis that this would create increased demand for […]

(Beyond Pesticides, June 7th, 2012) A new study confirms several other recent study findings on the inability of commonly used pyrethroid based pesticide products to control bed bug infestations. The results reinforce the voices of concerned citizens and environmental groups calling for a wider adoption of proven, non-toxic methods to manage bed bugs and other household pest problems. The study, entitled “Ineffectiveness of Over-the-Counter Total-Release Foggers Against the Bed Bug,“ was published in the June issue of the Journal of Economic Entomology. Researchers from Ohio State University focused on the efficacy of three over-the-counter ”˜foggers,’ or ”˜bug bombs,’ including Hotshot Bedbug and Flea Fogger, Spectracide Bug Stop Indoor Fogger, and Eliminator Indoor Fogger. Results from the study reveal that bed bugs are not affected by direct exposure to the pyrethriods present in these products. Even long-term laboratory populations of bed bugs, known to be susceptible to pyrethroids, were unaffected by the pesticide when given a thin cloth as cover. This means that even if the current strain of bed bugs in the U.S. were not resistant to pyrethriods, the chemical still would not be an effective method of control because of bed bugs’ propensity to hide in small cracks and […]

(Beyond Pesticides, June 7, 2012) As Hawaii officials finalize new rules for the regulation of pesticide discharge into waterways due to the federal court ruling requiring permits for pesticide discharges, critics say the state’s draft rules are not strict enough and that stakeholders, such as the farming lobby, may have had undue influence in crafting the new permitting requirements. Now that federal rules have been finalized to require National Pollutant Discharge and Elimination System (NPDES) permits under the Clean Water Act for pesticide discharges near waterways, as a result of a 2009 federal court order instructing EPA to require permits for pesticide discharges (see Daily News coverage), many states are rolling out their own rules to regulate these discharges. In Hawaii, a meeting called by state officials on Monday to hear public input was largely a battle between pro-pesticide interests, including Alexander & Baldwin, which sprays pesticides in irrigation ditches to control weeds, and state land officials, who use chemicals to kill invasive species, as well as Monsanto, that pushed to ease the rules, and environmental groups seeking to make them more stringent. Dean Okimoto, head of the Hawaii Farm Bureau, said that the rules would increase costs for farmers […]

(Beyond Pesticides, June 5, 2012) A new study finds that children exposed to high levels of naphthalene, a common air pollutant and the active ingredient in mothballs, are at increased risk for chromosomal aberrations (CA’s) that have been associated with increased cancer risk in adults. These include chromosomal translocations, a potentially more harmful and long-lasting subtype of CAs, which are of special concern as they result in a portion of one chromosome being juxtaposed to a portion of another chromosome, potentially scrambling the genetic script. Researchers from the Columbia Center for Children’s Environmental Health (CCCEH) at the Mailman School of Public Health, Columbia University Medical Center, and the Centers for Disease Control and Prevention (CDC) published the findings in Cancer, Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. “Translocations can persist for years after exposure. Some accumulated damage will be repaired, but not everyone’s repair capacity is the same. Previous studies have suggested that chromosomal breaks can double an adult’s lifetime risk for cancer, though implications for children are unknown,” says first author Manuela A. Orjuela, MD, ScM, assistant professor of clinical environmental health sciences and pediatrics (oncology) at Columbia University Medical Center and a […]

(Beyond Pesticides, June 4, 2012) France’s Agriculture Minister Stephane Le Foll announced plans on Friday to cancel Swiss manufacturer Syngenta’s registration to treat canola seed with the neonicotinoid insecticide thiamethoxam, a chemical cousin of the bee-killing pesticide clothianidin, in a move to protect honey bees from Colony Collapse Disorder (CCD). When honey bees are exposed to thiamethoxam, it breaks down in their bodies to, clothianidin, which Beyond Pesticides is petitioning the Environmental Protection Agency (EPA) to ban due to a preponderance of adverse effects data and inadequate registration safety testing. Both pesticides have been shown in numerous scientific studies to play a key role in CCD. As France acts to protect its pollinators from pesticides, the U.S. continues to allow the uses of theses highly toxic chemicals to continue. Tell Congress and EPA that the U.S. should join France in taking a precautionary approach to our pollinator crisis. The chemical manufacturer Syngenta has two weeks to report its own evidence before the ban officially goes into effect. If enacted, France’s Agriculture Ministry stated that the ban will take effect before the start of canola sowing season in late summer. Minister Le Foll reinforced the fact that farmers do not need […]

(Beyond Pesticides, June 1, 2012) Beyond Pesticides is pleased to announce the release of videos from Healthy Communities, the 30th National Pesticide Forum. The forum was held March 30-31, 2012 at Yale University School of Froestry and Environmental Studies in New Haven, CT and included leaders in the fields of pesticide reform, public health, organic agriculture, and alternative pest control as well as many community leaders, local activists, and students. The videos span the range of topics that were discussed at the Forum and include keynote speeches, panel discussions, and workshops. You can access the playlist, which includes all of the available videos of the 2012 forum, on Beyond Pesticides’ YouTube page. The videos include such notable presentations as: “Inventing the Future of Food“ by Gary Hirshberg — Mr. Hirshberg discusses organics, his experience with Stonyfield Farm and future of food. Mr. Hirshberg is chairman and co-founder of Stonyfield Farm, the world’s leading organic yogurt producer, and the author of Stirring It Up: How to Make Money and Save the World. Previously, he directed the Rural Education Center, the small organic farming school from which Stonyfield was spawned. Before that, he had served as executive director of The New Alchemy […]

(Beyond Pesticides, May 31, 2012) The Centers for Disease Control and Prevention (CDC) and the Maryland Department of Health and Mental Hygiene have enrolled Maryland households in a study that involves spraying the controversial pesticide bifenthrinon their property to determine the efficacy of this approach in controlling Lyme disease. Now in the beginning of its second year, the study found no evidence in the first year that the spraying works to reduce the transmission of Lyme disease. Beyond Pesticides is concerned that study participants have not been provided complete information about bifenthrin’s potential health risks to people. According to the Baltimore Sun, the study is an effort to find new ways to combat the disease, which infected 1,600 people in Maryland in 2010. Half of the 185 families that have volunteered for the study will have water sprayed on their lawns to serve as a control group, while the other half will receive the bifenthrin treatment. The 185 families that have signed up so far this year get a $25 gift card, lowered from $40 given to the 440 participants last year. Last year, while the pesticide reduced the amount of ticks on treated lawns compared to the control group, […]

(Beyond Pesticides, May 30, 2012) A settlement between plaintiffs and the manufacturer of the endocrine disrupting herbicide atrazine, Syngenta, will pay $105 million to settle a nearly 8-year-old lawsuit and could help reimburse community water systems (CWS) in 45 states that have had to filter the toxic chemical from its drinking water, according to news reports. It will provide financial recoveries for costs that have been borne for decades by more than 1,887 CWSs that provide drinking water more than one in six Americans across at least 45 states. “The scope of this historic settlement is enormous and its protection of the health of millions of Americans across the country is a huge benefit to the public, the environment, and the taxpayers,” the lead plaintiffs’ lawyer Stephen M. Tillery told the media. The individual amounts that eligible CWSs will recover will be calculated based on the levels of atrazine and frequency of atrazine contamination measured in the water of impacted CWSs and the population served by each CWS. The 300 CWSs with the highest contamination levels will recover 100 percent of their costs. Atrazine Settlement Details ”¢ Under the reported settlement, Syngenta will pay $105 million to pay the claims […]

(Beyond Pesticides, May 29, 2012) An industry newsletter has quoted representatives from two Washington, DC-based environmental organizations working on nanotechnology policy who blame the Obama Administration for impeding oversight of the largely unregulated technology. On May 23, Chemical Regulation Reporter quoted Richard Denison, PhD, a senior scientist with the Environmental Defense Fund, and Jaydee Hanson, senior policy analyst at the Center for Food Safety, as stating that two pending nanotechnology regulations have been placed on hold by the Office of Management and Budget (OMB). The delayed regulations involve separate proposed rules issued by the U.S. Environmental Protection Agency (EPA) that address engineered nanoparticles used as pesticides and chemicals, respectively. The article reported that Dr. Denison had spoken with EPA officials who told him that they do not expect any regulations for engineered nanoscale pesticides or chemicals to be approved by OMB. OMB is a powerful agency within the Executive Office of the President of the United States which exercises final authority for approving all significant regulatory actions initiated by Cabinet departments. “My understanding is that there is a view in some circles in the White House that they do not want to stigmatize nanomaterials nor stifle the technology even by […]

(Beyond Pesticides, May 25, 2012) Biologists at the University of California at San Diego (UCSD) have discovered that a small dose of the commonly used neonicotinoid crop pesticide imidacloprid turns honey bees into “picky eaters” and affects their ability to recruit their nestmates to otherwise good sources of food. The results of the experiments, detailed in this week’s issue of the Journal of Experimental Biology (abstract), shed light on one of the main culprits suspected to be behind the recent declines in honey bee colonies and detail the particular ways that the substance impedes the functions of the colony. Since 2006, beekeepers in North America and Europe have lost about one-third of their managed bee colonies each year due to “colony collapse disorder.” While the exact cause is unknown, researchers believe pesticides have contributed to this decline. One group of crop pesticides, called “neonicotinoids,” has received particular attention from beekeepers and researchers. Neonicotinoids, including clothianidin and thiamethoxam, in addition to imidacloprid, are highly toxic to a range of insects, including honey bees and other pollinators. They are taken up by a plant’s vascular system and expressed through pollen, nectar and gutation droplets from which bees forage and drink. They are […]

(Beyond Pesticides, May 24, 2012) On Tuesday, several hundred mothers and fathers joined nurses and cancer survivors at the U.S. Capitol to demand action on toxic chemicals. The group, deemed the “National Stroller Brigade” rallied in support of U.S. Senator Frank Lautenberg’s (D-NJ) Safe Chemicals Act, a bill to overhaul antiquated laws governing toxic chemicals. “It’s shocking that toxic chemicals end up in everyday consumer products, and in our bodies, without anyone proving that they are safe. The stroller brigade is carrying an important message to Congress that we’re not going to stand by and let our kids continue to be exposed to chemicals that make them sick. Concerned moms are the best weapons we have in this fight. With their help, I will keep advancing the Safe Chemicals Act to reform our broken toxic chemical laws and provide a healthier future for our families,” said U.S. Senator Frank R. Lautenberg (D-NJ). Public health groups have long urged Congress to strengthen the law by restricting chemicals known to be dangerous and requiring testing of new and existing chemicals to ensure that they are safe. The Safe Chemicals Act, utilizing risk assessment methodology, would, in theory, require chemical companies to prove […]

(Beyond Pesticides, May 23, 2012) University of South Florida (USF) researchers find that the commonly used fungicide chlorothalonil is lethal to a variety of freshwater organisms, including amphibians, snails, zooplankton, algae and aquatic plants below estimated environmental concentrations deemed safe by the U.S. Environmental Protection Agency (EPA). The research builds on a study published last year by the team which found that the fungicide is lethal to frogs at low doses, wiping out 87% of the population at the expected environmental concentration level. The study, entitled “Fungicide-induced declines of freshwater biodiversity modify ecosystem functions and services” was published in the journal Ecology Letters by USF biologists Taegan McMahon, PhD and Jason Rohr, PhD. The study was conducted over the course of four weeks using several 300-gallon tanks that were filled with water to mimic pond conditions. Using EPA calculations of how much chemical the farmer would use and how much would be expected to runoff into nearby bodies of water, they dosed the tanks with chlorothalonil. Though some species were able to recover from the chemical assault, researchers found that the ecosystem was fundamentally changed. “In addition, to reducing biodiversity and altering ecosystem functions, chlorothalonil reduced the decomposition of waste, […]

(Beyond Pesticides, May 22, 2012) The Spanish-based Inesfly company announced recently its plans to release commercially pesticide encapsulated paint, Inesfly 5A IGR, containing two neurotoxic organophosphates (OPs), chlorpyrifos and diazinon, and the insect growth regulator (IGR), pyriproxyfen, which it hopes will combat malaria in sub-Saharan Africa. The company’s owner Pilar Mateo, PhD, calls her product “a vaccine for houses and buildings” and explains that because the insecticides are released slowly from the paint, it remains effective for two to four years. This formulation of Dr. Mateo’s paint could not be registered for use in the U.S. because both indoor residential uses of chlorpyrifos and diazinon have been banned because of risks posed to children’s health, although the company has another formulation that substitutes pyrethroids for the organophosphates. Though probably well-intentioned —Dr. Mateo has already invested $6 million of her family’s money and $12 million in grants from nonprofits, on research, creating educational programs about hygiene, and donating paint to more than 8,000 homes in Latin America and Africa””the product puts the people it is supposed to protect from disease at risk for other health problems. Organophosphate insecticides have been linked to a host of neurodevelopmental problems, especially in children. Because […]

(Beyond Pesticides, May 21, 2012) American farmers are growing increasingly more frustrated with the lack of commercially available seeds that have not been pretreated with pesticides. Farmers across the Midwest have called on federal officials this week to provide greater access to seeds without pesticide treatments. The request comes as scientists and beekeepers highlight the nearly pervasive use of neonicotinoids as seed treatments on corn as a critical factor in recent bee die-offs, including colony collapse disorder (CCD). Beekeepers from Minnesota to Ohio to Canada report large losses after their hives forage near treated cornfields. Scientists from Purdue University and a multi-year series of studies from Italy point to toxic dust, or neonicotinoid-contaminated powder from recently planted corn fields as key pesticide exposure pathways for bees. The request comes on the heels of a report aired by NBC Nightly News this week entitled “Bee Deaths Linked to Pesticides”, as well as recent reports of large bee kills in Ohio. “Farmers want to be good stewards and neighbors by purchasing seeds and growing corn that supports healthy honey bees and successful beekeepers,” said Doug Voss, a Minnesota corn farmer who also keeps beehives. We have a genuine concern with the majority […]

(Beyond Pesticides, May 18, 2012) A groundbreaking report documents the potential for antibiotics used in the production of corn-based ethanol to contribute to the emergence of antibiotic-resistant bacteria. The potential for the misuse of antibiotics in industrial agriculture to spawn antibiotic-resistant bacteria has long been recognized, but the new report sheds light on a dimension of the problem that has largely gone unnoticed. Entitled Bugs in the System and published by the Institute for Agriculture and Trade Policy (IATP), the report establishes that antibiotic residues found in the by-products of ethanol production are strong enough to promote resistance in pathogenic bacteria when those by-products are fed to livestock. The report points out that for life-threatening bacterial infections in humans, there are no alternatives to antibiotics and that once resistant bacteria develop from antibiotic misuse, we have forever lost an effective treatment for the illness. For at least two decades, antibiotics have been an important component of the fermentation process used to make ethanol. Corn ethanol is the product of starches broken down into sugars by yeast. The sugars are then fermented and distilled, all of which happens in tanks full of warm water, a perfect environment not only for yeast […]
