(Beyond Pesticides, July 5, 2012) After a 2006 cancellation of uses due to unreasonable risks to farmworker health and the environment, and a 6-year phase out scheduled to conclude this September, the U.S. Environmental Protection Agency (EPA) is conducting a risk-benefit analysis to make a determination whether to keep in place or amend the cancellation order for the organophosphate azinphos-methyl (AZM), citing new information on the economic costs of using alternatives. In 2001, EPA found that insecticides azinphos-methyl (AZM) posed unacceptable risks to farmworkers and announced that 28 crop uses were being canceled, seven crop uses were to be phased-out over four years, and eight crop uses were to be allowed to continue under a “time-limited” registration for another four years. Farmworker advocates challenged that decision in federal court citing that EPA failed to take into account the costs of poisoning workers, exposing children, and polluting rivers and streams. A settlement agreement effectively stayed the legal challenge pending EPA’s reconsideration of the “time limited” uses of AZM. In November 2006, EPA decided that AZM poses unreasonable adverse effects and issued a final decision to cancel AZM, but allowed continued use on some fruit crops (apples, cherries, pears) for six more […]

(Beyond Pesticides, June 29, 2012) New research from the McGill University Health Centre (MUHC) in Montreal suggests that pesticide exposure, as well as smoking, head injury, farming, and less education, may be a risk factor for a rare sleep disorder that causes people to kick or punch during sleep, according to a study entitled “Environmental risk factors for REM sleep behavior disorder: A multicenter case-control study” published in the June 27, 2012, online issue of Neurology, the medical journal of the American Academy of Neurology. People with the disorder, called REM sleep behavior disorder, do not have the normal lack of muscle tone that occurs during rapid eye movement (REM) sleep, causing them to act out their dreams. The movements can sometimes be violent, causing injury to the person or their bed partner. The disorder is estimated to occur in 0.5 percent of adults. “Until now, we didn’t know much about the risk factors for this disorder, except that it was more common in men and in older people,” said study author Ronald B. Postuma, MD, MSc, with the Research Institute at MUHC and a member of the American Academy of Neurology. “Because it is a rare disorder, it was […]

(Beyond Pesticides, June 28th 2012) The Canadian province of Manitoba is asking for public feedback on whether to ban the sale and/or use of cosmetic pesticides for lawn care. This request comes on the heels of a May 17 recommendation by a special committee in the Canadian provincial government of British Columbia (BC) not to enact an all-out ban on cosmetic pesticides. Currently, seven Canadian provinces have enacted pesticide regulation, each with varying degrees of restrictions. The public has until October 1 to submit their comments on the ban to the Manitoba government. The province is providing guidance to the public through a paper titled Play it Safe, which outlines the background on the proposed ban, explores restriction options, and raises awareness about pesticide use on lawns. The paper makes note of the importance of using a precautionary approach to the sale and use of lawn care pesticides, acknowledging the potential harm these chemicals can cause to the environment and human health, especially those at increased risk, such as pregnant women and children. Environmental groups and public health organizations, including the Canadian Cancer Society, the Canadian Association of Physicians for the Environment (CAPE), and The David Suzuki Foundation are all […]

(Beyond Pesticides, June 27, 2012) One county in New Jersey is getting serious about combating mosquitoes this season. Instead of relying on pesticide spraying, which has been shown to not be effective, the Cape May County Department of Mosquito Control is employing 10,000 tiny shrimp-like crustaceans that will eat their way through mosquito larvae in the county’s swamps, roadside ditches and small pools. The latest weapon in the battle against mosquitoes is barely visible. The crustaceans, known as copepods, are cousins to crayfish and water fleas, and do not get much bigger than two millimeters. They are voracious predators of mosquito larvae. New Jersey recently delivered 10,000 of the tiny shrimp-like crustaceans to Cape May County. They are already being used to fight mosquitoes in Bergen, Passaic, and Morris counties. Ocean County is next on the delivery list and six other counties will follow. “The days of driving a truck down the street and spraying pesticides are long gone. These copepods can pick up where fish leave off,” according to Administrator Robert Kent, of the state Office of Mosquito Control. Natural Predators as a Solution for Mosquito Control New Jersey has used mosquitofish, fathead minnows, killifish, bluegill and other fish […]

(Beyond Pesticides, June 25, 2012) The Canadian governmental authority responsible for pesticide registration has expanded its re-evaluation of neonicotinoid pesticides to include two additional compounds linked to honey bee deaths and Colony Collapse Disorder (CCD). Health Canada’s Pest Management Regulatory Agency (PMRA) announced on June 12 that it has added clothianidin and thiamethoxam and their associated products to its ongoing re-evaluation of imidacloprid. The re-evaluation of these pesticides will focus on resolving issues related to environmental risk and specifically the potential effects of neonicotinoids on pollinators. The re-evaluation will consider all agricultural uses of neonicotinoid insecticides, including soil applications, seed treatment, as well as foliar and greenhouse uses. The Canadian announcement follows France’s decision earlier this month to initiate its own review for thiamethoxam that could result in the cancelation of allowances for using the pesticide. Neonicitinoids 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. Neonicotinoids are particularly dangerous because, in addition to being acutely toxic in high doses, they also result in serious sublethal effects when insects are exposed to […]

(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 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 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 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, 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 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 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 […]

(Beyond Pesticides, May 16, 2012) With Congress considering drastic cuts to national clean water protections, and rivers nationwide facing threats from natural gas drilling, chemical pollution, and new dams, American Rivers yesterday released its annual list of America’s Most Endangered Rivers. ® It names the Potomac River, known as ”˜the nation’s river’ as it flows through the capital, the most endangered in the country. While the Potomac is cleaner than it used to be, the river is still threatened by urban and agricultural pollution —and it could get much worse if Congress rolls back critical clean water safeguards. As the country commemorates the 40th anniversary of the Clean Water Act this year, the Potomac is emblematic of what is at stake for rivers nationwide. American Rivers launched a national call to action, giving citizens the opportunity to contact members of Congress and speak up for clean water. The report, “America’s Most Endangered Rivers,” notes that urban development is funneling tons of polluted rainwater to the river, that chemical fertilizer and manure from farms make matters worse, and that wastewater overflowing from sewers, along with pharmaceuticals flushed down toilets, contribute to dead zones in which marine life dies and might cause […]

(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 11, 2012) The Canadian General Standards Board (CGSB) has released the final version of the Canadian Organic Aquaculture Standard, a non-binding system for certifying farmed fish outside of official Canadian organic standards. The final standard is a revised form of a draft standard first proposed in 2010, which was subject to severe criticism from environmental advocates. The standard has been developed independently of Canadian organic standards for agriculture and is not currently included in official government regulations regarding organic agriculture. The release comes less than two weeks before the U.S. National Organic Standards Board (NOSB) will meet to discuss, among other topics, the ongoing process of developing a standard for organic aquaculture in the United States. The new standard was developed by under the auspices of the Canadian National Standards Board and is purely voluntary. In Canada, as in the U.S., fish are are explicitly excluded from federal organic regulations. This means that there can be no official, government-approved organic fish in either country currently. However, this also means that there is nothing stopping private entities from creating their own standard for certifying fish as “organic” according to whatever definition they choose. The fish can then be […]

Beyond Pesticides, (May 10, 2012), British Columbia (BC) may become the eighth Canadian province to ban cosmetic (lawn care) pesticides after the Special Committee on Cosmetic Pesticides submit their recommendations to the legislature later this month. The report will outline the bipartisan committee’s findings from over the last eight months on restrictions for non-essential pesticides use province-wide. Roughly forty municipalities throughout the province already have pesticide bans in place, and a survey found that a majority of Metro Vancouver voters across political party lines endorse a province-wide ban on the sale and use of lawn and garden pesticides. Though it is widely popular, environmental groups and human health organizations are expecting industry backlash and have expressed concern about whether or not recommendations will be strong enough and whether effective legislation will result. “The poll shows nearly two-thirds of Vancouverites know pesticides are linked to childhood cancer,” said Canadian Association for Physicians for the Environment (CAPE) Executive Director Gideon Forman. “Among people with kids, support for a pesticide ban is at 76 per cent,” said Mr. Forman. “Candidates who endorse a strong provincial pesticide ban will be very popular with families.” It’s believed to be the first time in British Columbia […]

(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 […]
