(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 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 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 17, 2012) Rather than investing in safe, long-term solutions to prevent malaria mortality, the World Health Organization (WHO) has issued a strategic plan that calls for multiple toxic pesticides to combat mosquito resistance to insecticides that is showing up in sub-Saharan Africa. Insecticide resistance, according to the WHO report, is already rampant in 64 malaria-ridden countries and may result in as many as 26 million more cases of malaria a year, which could end up costing between $30 and $60 million annually for tests and medication. Mosquitoes in sub-Saharan African countries are becoming resistant to pyrethroid insecticides, which are used extensively for household spraying and treating bed nets, as well as to the organochloride compound DDT -which is still used in many parts of the world to control mosquitoes. In Somalia, Sudan and Turkey, resistance has spread to carbamates and organophosphates in addition to pyrethroids and organochloride pesticides. Rather than reducing the reliance on these products, WHO is recommending rotating classes of pesticides used to spray inside homes and developing a new non-pyrethroid insecticide to treat bed nets. Implementation for these suggestions are estimated to cost around $200 million, which is in addition to the $6 billion […]

(Beyond Pesticides, May 15, 2012) Dow AgroSciences and Monsanto have filed paperwork for Canadian approval of corn and soybeans genetically engineered (GE) to withstand heavy applications of potent herbicides, reports the Ottawa Citizen. The chemical companies are seeking Health Canada and Canadian Food Inspection Agency assessments for the introduction of four varieties of GE corn and soybeans engineered to tolerate the highly toxic herbicides 2,4-D and dicamba. In the U.S., the federal Department of Agriculture (USDA) is in the process of reviewing Dow’s application for its 2,4-D-tolerant corn, as well. Beyond Pesticides and others recently submitted comments to USDA challenging this approval. Dow’s GE corn is modified to be tolerant to 2,4-D, which is contaminated with dioxin and linked to cancer, birth defects, and more. The company is introducing the new GE corn variety because weeds are becoming resistant to Roundup, the previous chemical of choice for herbicide-tolerant plants. However, solving herbicide resistance with a new, more toxic chemical is like using gasoline to put out a fire. It will cause even more damage to health and the environment, and in a few years, the pesticide industry will be marketing their next “solution” to the growing resistance problem. Dow states […]

(Beyond Pesticides, May 14, 2012) The U.S. Environmental Protection Agency (EPA) is accepting public comment on several complex regulatory issues related to the agency’s commitment to phase out the toxic fumigant sulfuryl fluoride. At one time EPA had supported sulfuryl fluoride as a replacement for a second fumigant, methyl bromide, which the United States is obligated under international treaty to eliminate due to its contribution to ozone depletion. However, EPA reversed that support once further research and a refined risk assessment established that aggregate exposure to sulfuryl fluoride does not adequately protect the health of certain population subgroups. Although EPA decided unequivocally in 2011 to phase out all food-related uses for sulfuryl fluoride, the current public comment opportunity revisits key elements of that decision and could open the door for an unwarranted and unnecessary extension of this toxic fumigant’s allowance. Initially registered in 1959 to kill termites and other wood-boring pests, sulfuryl fluoride gained attention as a potential alternative to methyl bromide as a broad spectrum insect fumigant in post-harvest commodity storage and food processing facilities. The need for such alternatives became more pressing as the U.S., a signatory of the Montreal Protocol, gradually reduced the amount of methyl bromide […]

(Beyond Pesticides, May 9, 2012) In what is being presented as “a clear risk to British farming,” protesters in the United Kingdom have organized a campaign to protest field sites being used to test a new strain of genetically modified (GM) wheat. The industry developing the GM wheat is asking the campaigners not to ruin their experimental plots, but the group, ”˜Take the Flour Back,’ has vowed to “decontaminate” the site unless the research is halted. The “Take the Flour Back” campaign is protesting the outdoor field trials of a new strain of GM wheat which has the potential to contaminate surrounding fields and spread GM material to others areas off-site. Campaigners say controlled indoor trials should be done instead before the crop is planted outdoors. The trial at Rothamsted Research in Harpenden, Herts in South East England is evaluating the efficacy of wheat modified to deter aphids, an insect pest. Rothamsted Research insists this minimizes crop losses due to aphid attack and the fungal infections and viruses that can follow in their wake, and reduces the need for chemical spraying against aphids. Rothamsted agricultural research establishment is set to conduct open air trials of wheat to be planted in […]

(Beyond Pesticides, May 7, 2012) The U.S. Department of Agriculture (USDA) has quarantined a second California farm as part of its ongoing investigation into a confirmed incidence of Bovine Spongiform Encephalopathy (BSE), first reported on April 24. USDA quarantined the second farm because it is operated in close association with the dairy that housed the BSE-infected cow before its condition was detected. Additionally, USDA is investigating the ranch where the BSE-infected cow was raised 10 years ago. USDA also announced that of the two progeny known to have been born to the BSE-infected cow in the past two years, one was stillborn and the second, after being humanely euthanized, tested negative for BSE. The origin and transmission of BSE to hundreds of thousands of cattle has been widely attributed to using cattle rendered protein produced from the carcasses of scrapie-infected sheep or cattle with a previously unidentified form of transmissible spongiform encephalopathy as livestock feed. This widespread practice of feeding substances derived from animals to other animals (even of the same species) was sharply curtailed following the BSE epidemic in the U.S. and Europe, but never fully eliminated. For example, livestock feed regulations in the U.S. continue to allow the […]

(Beyond Pesticides, May 2, 1012) New research published online at the Proceedings of the National Academy of Sciences reports that babies exposed in the womb to a commonly used insecticide have brain abnormalities after birth. The insecticide, chlorpyrifos (used in agriculture, mosquito control, and golf course management) , is well documented as inducing neurodevelopmental abnormalities in infants exposed in their mother’s womb, including ADHD, cognitive deficits, and serious learning, behavioral or emotional disorders. Entitled, “Brain anomalies in children exposed prenatally to a common organophosphate pesticide,” the study investigated associations between chlorpyrifos exposure and brain morphology using magnetic resonance imaging in 40 New York City children. It found significant associations of prenatal exposure, at standard use levels, with structural changes in the developing human brain, including enlargement of superior temporal, posterior middle temporal, and enlarged superior frontal gyrus, gyrus rectus, cuneus, and precuneus along the mesial wall of the right hemisphere. These areas of the brain impacted are related to attention, language, reward systems, emotions and control may be affected by the chemical. Twenty high-exposure children (upper third of chlorpyrifos concentrations in umbilical cord blood) were compared with 20 low-exposure children. The children, ages 6-11 years, considered to have a high […]

(Beyond Pesticides, April 25, 2012) Researchers at Portland State University have found that the cultivation of corn genetically engineered (GE) to express the insecticidal soil bacterium Bacillus thuringiensis (Bt) has negative impacts on beneficial soil life. The research team, led by PhD student Tanya Cheeke, was interested in determining whether the cultivation of Bt corn has a negative effect on arbuscular mycorrhizal fungal colonization of Bt corn or of crops subsequently planted in the same soil. Their findings, published in the April 2012 issue of the American Journal of Botany, show a decreased presence of the beneficial fungi in the roots of Bt corn when compared to non-Bt corn. Bt corn is genetically engineered to express insecticidal toxins derived from Bt in an effort to protect it against common agricultural pests such as the corn root worm and European corn borer. Recent findings have shown, however, that insects are growing increasingly resistant to the toxin, due in part to a breakdown in resistance management implementation. Additionally, researchers in Europe recently found evidence that Bt is toxic to human cells in large doses. Arbuscular mycorrhizal fungi (AMF) are ubiquitous microscopic soil fungi that form symbiotic relationships with the roots of most […]

(Beyond Pesticides, April 24, 2012) Dow Chemical has asked USDA for approval of genetically engineered (GE) corn, modified to be tolerant to the highly toxic 2,4-D herbicide, which is contaminated with dioxin and linked to cancer, birth defects and more. We know from experience that herbicide-tolerant crops are a bad idea. They increase toxic pesticide use, contaminate organic and non-GE farms, and contribute to herbicide-resistance. In fact, Dow introduced a new GE corn variety because weeds are becoming resistant to Roundup, the previous chemical of choice for herbicide-tolerant plants. However, solving herbicide resistance with a new, more toxic chemical is like using gasoline to put out a fire. It will cause even more damage to health and the environment, and in a few years, the pesticide industry will be marketing their next “solution” to the growing resistance problem. Read Beyond Pesticides full comments to USDA for Dow’s petition to approve 2-4,D-resistant GE corn. Tell USDA to stop this toxic experiment and deny Dow’s petition for 2,4-D tolerant corn. Sign your organization or business onto Beyond Pesticides’ comments or submit comments directly to the USDA docket. The deadline to sign on is Friday, April 27 at noon. Background: In a radio […]

(Beyond Pesticides, April 23, 2012) A diverse coalition of farm groups has petitioned the U.S. Department of Agriculture (USDA) to conduct a comprehensive environmental impact statement on the cumulative effects of a new generation of genetically engineered (GE) crops modified to tolerate the herbicides 2,4-D and dicamba. The Save Our Crops Coalition filed the petition in advance of an anticipated spike in applications of the two herbicides in 2013 with the commercial release of a new generation of “stacked” corn and soybean varieties, which will also be resistant to the herbicide glyphosate. In the petition, the coalition stated that 2,4-D and dicamba have been proven to be especially prone to volatilization and drift and that even extremely low residue levels can cause catastrophic damage to non-target crops as far as ten miles from the point of application. The petition raises specific concerns about the increased 2, 4-D and dicamba usage due to the timing of the herbicide applications. The new blended 2,4-D or dicamba and glyphosate herbicides will be sprayed repeatedly during the growing season after weeds emerge and begin to compete with crops. Spraying herbicides, which are known to volatilize and drift during periods when specialty crops are at […]

(Beyond Pesticides, April 20, 2012) The public comment period on proposals from the National Organic Standards Board (NOSB) regarding updates to standards governing organic food and farming remain open until then end of Thursday May 3, 2012. Beyond Pesticides has updated our Keeping Organic Strong web page with information on a number of issues that the board will consider at its meeting in Albuquerque, NM May 22-25, 2012.

Many of the proposed recommendations are available […]

(Beyond Pesticides, April 19, 2012) The University of Texas (UT) Student Government body unanimously passed a resolution last month to ban soap containing the toxic antibacterial chemical triclosan throughout campus. If the ban is accepted by the University administration, UT would be the first university in the country to take an official stance against one of the most prevalent and dangerous antibacterial products available. Triclosan, which can be found in many personal care products, has been linked to numerous human and environmental health effects. Recently the Canadian government declared triclosan as an environmental toxin, proposing regulations to restrict its use. Student Government (SG) representative and public affairs graduate student Robert Love, who initiated the ban, says that officials in several different campus purchasing departments are open to phasing out antibacterial soap. For financial and environmental reasons, the University phased out the use of the triclosan-containing soap in restrooms across campus in 2008; however, it is still being used in other places on campus. According to a university spokeswoman, a campus-wide phase out would require an official decision. “What we’re saying is we need an outright ban on campus, and we need to kind of make a bold statement,” said urban […]

(Beyond Pesticides, April 16, 2012) The U.S. National Marine Fisheries Service (NMFS) has released a draft Biological Opinion finding that three commonly used herbicides are increasing the chance of extinction for threatened and endangered Pacific salmon and steelhead runs. The NMFS assessment reverses earlier assurances from the U.S. Environmental Protection Agency (EPA) that the pesticides are “not likely to adversely affect” the dwindling salmon populations. The draft Opinion also contains restrictions on applying the three pesticides near waterways in California, Washington, Oregon and Idaho that provide habitat for the threatened and endangered runs. Public comment on the draft is being accepted through April 30 and the restrictions on applying the pesticides will take effect no later than one year after the final assessment is released. NMFS prepared the draft Opinion in response to EPA’s initial assessment of the risk that current uses of the herbicides oryzalin, pendimethalin and trifluralin pose for the threatened and endangered salmon and steelhead species. NMFS’ findings contradict significant conclusions from EPA’s work and highlight weaknesses in the agency’s current ecological risk assessment process that underestimate risk and fail to meet modern standards of analysis. For example, NMFS cites EPA’s failure to provide any analysis of […]

(Beyond Pesticides, April 13, 2012) A study has found that the children of flower plantation workers in Ecuador are neurologically affected by the pesticide residues that their parents unwittingly carry home on their clothes, tools, and skin. The study documents significantly reduced activity for the essential enzyme acetycholinesterase (AChE) in children whose parents work on flower plantations compared to others whose parents do not. The two main classes of pesticides that the researchers identify as used in the region’s flower production, organophosphates and carbamates, are known to suppress the enzyme’s activity. AChE activity is crucial to healthy neurological functioning in humans and its suppression during childhood can hinder nervous system and cognitive development causing immediate and long-term impairment. In the study, Lower acetylcholinesterase activity among children living with flower plantation workers (Environ Res. 2012 Apr;114:53-9. Epub 2012 Mar 10), children whose parents work on a flower plantation are more than three times more likely to be in the group of lowest AChE activity. Additionally, the children who live the longest with a flower plantation worker are four times more likely to have lower enzyme activity than children who never live with a plantation worker. The researchers obtained their results by […]

(Beyond Pesticides, April 12, 2012) The U.S. Environmental Protection Agency (EPA) announced Monday that it has rejected a petition to ban the widely used herbicide 2,4-D, dismissing epidemiologic studies that link the pesticide to cancer, endocrine disruption, and other human health effects. In its announcement, EPA also responded to comments that Beyond Pesticides submitted in 2009, dismissing two studies that evaluate the relationship between the use of the chemical on lawns and the incidence of malignant lymphoma in pets. The petition was initially filed in 2008 by the Natural Resources Defense Council (NRDC). 2,4-D has been used in the U.S. since the 1940s, and as such is one of the oldest registered herbicides in the country. It made up roughly half of the herbicide known as Agent Orange, which was used to defoliate forests and croplands in the Vietnam War. According to EPA, 2,4-D is currently found in approximately 600 products registered for agricultural, residential, industrial, and aquatic uses. The use of 2,4-D is expected to increase significantly in the next few years with the recent announcement that Dow AgroSciences, the main manufacturer of the chemical, is seeking federal approval to sell corn seeds that have been genetically engineered to […]

(Beyond Pesticides, April 11, 2012) U.S. Representative Keith Ellison (D-Minn.) reintroduced legislation (H.R.4318), “To prohibit the use, production, sale, importation, or exportation of any pesticide containing atrazine,” on March 29. Atrazine is used nationwide to kill broadleaf and grassy weeds, primarily in chemical-intensive corn production. Upon introduction Rep. Ellison pointed out that a U.S. Geological Survey finds atrazine in approximately 75 percent of stream water and 40 percent of groundwater sampled near agricultural areas. The bill complements calls by Beyond Pesticides and other advocacy groups to ban this dangerous chemical. Previously, a similar bill was introduced in 2010 (H.R. 5124), which remained in committee. H.R. 4318 states, “The toxicity of atrazine is well documented and has shown to have adverse endocrine effects in amphibians, mammals, and humans. There is evidence that atrazine exposure is associated with low sperm counts and poor motility in exposed adult men, and that prebirth atrazine exposure is associated with small birth weight and abnormal development of the gut wall in infants. In laboratory mammals, exposure is associated with abnormal reproductive system development, impaired prostate gland formation, and abnormal breast tissue development. In aquatic wildlife, exposure is associated with abnormal reproductive system development, impaired reproduction, and […]

(Beyond Pesticides, April 9, 2012) A new study finds that exposure of pregnant women to organophosphate (OP) pesticides —a widely used class of pesticides in North American agriculture— may affect both length of pregnancy and birth weight. Environmental Health Perspectives published the paper, “Associations of Prenatal Exposure to Organophosphate Pesticide Metabolites,” last Thursday, April 5, 2012. The study, by a Simon Fraser University researcher, finds that the population of 306 women in Cincinnati, Ohio, is representative of the type of exposures most North American women and their children experience. Although the use of OPs in Canada and the U.S. has declined in recent years, exposures remain widespread, and these findings add to growing evidence about the harmful effects of low-level exposures to environmental toxicants. The researchers collected urine from each of the women in Cincinnati twice during their pregnancies for organophosphate metabolites as well as other factors that could influence the fetus’ health, including exposure to second hand smoke, race, and poverty. Women with higher levels of organophosphates were found to have pregnancies that were three to four days shorter and babies that were about â…“ pound lighter on average than women with lower levels of pesticides. “For an individual […]
