(Beyond Pesticides, April 8, 2013)  Given the rise of targeted plant and animal pests that are resistant to the tactics of the biotechnology industry, companies that produce genetically engineered (GE) crops have begun producing plants with “stacked” traits. For herbicide resistant crops, this means adding traits that incorporate crop resistance to increasingly dangerous and toxic chemicals, such as 2,4-D, a major component in the Vietnam-era herbicide Agent Orange. For crops engineered to produce their own natural insecticide, namely the toxin Bacillus thuringiensis, this means adding new formulations of the bacterium. Although this practice is widely considered acceptable and effective by the biotechnology industry, a new study from the University of Arizona College of Agriculture and Life Sciences, published in the journal PNAS, casts doubt on this assumption. Most scientists assume that two-toxin plants will be more durable than one-toxin plants. The extent of the advantage of the pyramid strategy, however, rests on assumptions that are not always met, the study reports. “The pyramid strategy has been touted mostly on the basis of simulation models,” said Yves Carrière, PhD, lead author of the study. “We tested the underlying assumptions of the models in lab experiments with a major pest of corn […]

(Beyond Pesticides, April 3, 2013)   Last week, Syngenta and Bayer CropScience proposed an action plan to forestall pending European Union (EU) restrictions on their neonicotinoid products that have been linked to global bee declines.   Stating that a ban on their products would not save hives, the plan focuses on implementing agricultural best management practices, planting habitat, and new research and development, all of which fail to seriously address the real problem that their products are highly toxic to bees. This new industry plan comes on the heels of the European Union (EU) stalemate on bee health, and after the EU food safety agency concluded that certain neonicotinoids pose unacceptable risks to bees. Public and regulatory scrutiny is now focused on the class of chemicals — neonicotinoids— linked to bee health decline. Neonicotinoids have been shown by numerous studies to adversely impact the health of  bees, as well as  birds and aquatic organisms. Beyond Pesticides, Center for Food Safety, and Pesticide Action Network North America joined beekeepers and other environmental and public health advocacy groups to sue the U.S. Environmental Protection Agency (EPA), calling for the suspension of the neonicotinoids, clothianidin and thiamethoxam. The science continues to document these […]

(Beyond Pesticides, April 2, 2013) On March 26, President Obama signed into law House Resolution 933, a stop-gap Continuing Resolution(CR) that allowed the U.S. to avoid a government shutdown for six months. The resolution contains the “biotech rider,” or amendment that takes away the authority of federal courts to halt the sale or production of genetically engineered (GE) crops, undermining the courts’ ability to protect farmers and the environment from potentially hazardous GE crops- a major violation of the separation of powers, an essential element of U.S. constitutional governance and law.  It would also compel the U.S. Department of Agriculture (USDA) to immediately grant any requests for permits to allow continued planting and commercialization of unlawfully approved GE crops. The rider, section 735 of the resolution, also dubbed the “Monsanto Protection Act” for the GE corporate  giant, was never voted on and was written by Senator Roy Blunt (R-MO), who worked with Monsanto to craft its language. This new rule will be viewed as a challenge for environmental organizations as courts have played an important role in slowing the growth of GE industry due to noncompliance with environmental law. In early March, Beyond Pesticides reported that a coalition of over […]

(Beyond Pesticides, March 29, 2013) Two studies released Wednesday support the findings of the European Food Safety Authority that neonicotinoid insecticides pose an unacceptable risk to bees. The pair of British studies indicate that neonicotinoids and miticides cause brain damage, compromising bee survival. The study, published in Nature Communications by researchers at the University of Dundee and Newcastle University, concludes that imidacloprid  and clothianidin, a commonly used insecticides on crops and plants, as well as the organophosphate miticide coumaphos, a treatment for Varroa bee mites, cause cognitive damage in bees. The research indicates that within 20 minutes of exposure to pesticides the neurons in the learning center of the brain stop firing, causing “epileptic type” hyperactivity. While the bees are still alive, the lobes of the brain fail to communicate with each other with obvious implications for their survival, Another study, published in the Journal for Experimental Biology by a team of Newcastle scientists, links imidacloprid and coumaphos to learning and memory impairment. The research indicates that brain damage from pesticides makes it more difficult for bees to forage and find food, and when they find the food they have trouble locating and returning to their hives. In sum, the […]

(Beyond Pesticides, March 28, 2013) A scathing new report by the Natural Resources Defense Council (NRDC) sheds much needed light on the flaws in the Environmental Protection Agency’s (EPA) pesticide approval process, noting that in terms of the agency’s ability to offer transparency and rigorously test these inherently toxic chemicals, “the public’s trust is misplaced.” The recent lawsuit brought about by a coalition of beekeepers, consumer, and environmental groups, including Beyond Pesticides, emphasizes the harm resulting from EPA’s  abuse of the statutory  “conditional registration” program.  Through this program,  EPA has  allowed  the wide and growing use of the systemic neonicotinoid pesticides that are  linked to the dramatic decline in honey bee health and viability of honey bee colonies. A startling number of pesticides, nearly 65% of the more than 16,000 pesticides now on the market, were first approved by the process of “conditional registration,” a loophole in which EPA allows new pesticides on the market without the full range of legally mandated toxicity tests. NRDC accuses EPA of misusing the conditional registration process, and their assertions are by no means unfounded. The report cites EPA’s own 2004-2010 internal analysis that ultimately determined the agency had misused the provision “98 percent […]

(Beyond Pesticides, March 26, 2013) Scientists are learning more about the mechanisms bed bugs have developed to increase their resistance to the increasingly common class of pyrethriod pesticides. The study, published in the journal Scientific Reports in early March, adds further weight to calls from consumer health and environmental groups to adopt proven, non-toxic strategies to manage bed bugs and other household pest problems. After all, if alternatives exist, why put your family at risk with unsustainable, ineffective control methods? This latest research reveals something scientists had not suspected. Bed bugs are developing most of their resistance-associated genes on the outer layer of their shell. These genes either neutralize the insecticides before they can take effect, or slow down the toxins’ move towards the insects’ nerve cells. In addition, bed bugs in the study also show resistance developing within their nerve cells, the target site for the pesticides. This multilayered resistance is unique, scientists say, but, as Beyond Pesticides has long documented, pest resistance to pesticides is not. A 2011 study from Ohio State University reveals bed bugs’ ability to evolve hereditary changes in their production of certain enzymes, allowing them to excrete the toxins without being harmed. A study […]

(Beyond Pesticides, March 21, 2013) Beyond Pesticides joins beekeepers, environmental and consumer groups in filing a lawsuit in Federal District Court against the U.S. Environmental Protection Agency (EPA) for its failure to protect pollinators from dangerous pesticides. The coalition seeks suspension of the registrations of insecticides- clothianidin and thiamethoxam- which have repeatedly been identified as highly toxic to honey bees, clear causes of major bee kills and significant contributors to the devastating ongoing mortality of bees known as colony collapse disorder (CCD).  The suit challenges EPA’s oversight of these bee-killing pesticides, as well as the agency’s practice of “conditional registration” and labeling deficiencies. Beyond Pesticides joins The Center for Food Safety, Pesticide Action Network North America, the Sierra Club, the Center for Environmental Health, and four beekeepers: Steve Ellis of Old Mill Honey Co. (MN, CA), Jim Doan of Doan Family Farms (NY), Tom Theobald of Niwot Honey Farm (CO) and Bill Rhodes of Bill Rhodes Honey (FL). See Press Release. Read the 2013 Lawsuit, Appendix A: Clothianidin, Appendix B: Thiamethoxam. Handing the Reins to Industry The lawsuit comes on the heels of the recent Pollinator Summit, hosted by EPA with the aim to “advance our understanding and our efforts […]

(Beyond Pesticides, March 18, 2013) The bee-killing neonicotinoid insecticides used for agriculture will continue to be used across the European Union (EU), as members failed to reach an agreement on the proposal to suspend their use on flowering crops over the next two years. The proposal had followed reports released by the European Food Safety Authority (EFSA), which found the continued use of neonicotinoids to be an unacceptable “high acute risk” to pollinators, particularly honey bees. However, three EU members opposed the plan to suspend, blocking the European Commission from attaining a qualified majority to adopt the proposed suspension. “The commission put the text to the vote and no qualified majority was reached, either in favor or against the text,” the European Commission said in a statement. Those opposing the proposal, notably UK and German Ministers, argued that more scientific evidence was needed as a suspension could cause disproportionate damage to food production, counter to research indicating bee declines also damage crop productivity. Pesticide companies Bayer and Syngenta have pressed hard following the EFSA report to effect this outcome. The decision, or lack thereof, runs contrary to a precautionary approach to ensuring healthy bees as critical for our food production […]

(Beyond Pesticides, March 15, 2013) A group of Washington D.C. area activist led by Alan Cohen, the president of Safe Lawns for DC Kids and Critters, and Beyond Pesticides delivered a petition to the National Park Service (NPS) that urges officials to stop the seasonal spraying of Rodeo, a glyphosat-based herbicide, to control for fig buttercup in Rock Creek Park in the DC metropolitan area. The group is asking the park to adopt an alternative weed management strategy. According to Mr. Cohen, “We are not saying they should do nothing. We should do something to manage this invasive plant, but it shouldn’t be this treatment with Rodeo.” The activist group gathered over 250 signatures to a petition that asks the park service to stop the spraying of Rodeo by canvassing in the park over several weekends and through their online petition. The group argues that spraying within 25 feet of waterways violates DC’s Pesticide Education and Revisions Act of 2012.  The group says that through this process of petitioning that they want to start a dialog between community members and the NPS on how to best manage fig butter cup. However, NPS has not been responsive to this request. The […]

(Beyond Pesticides, March 8, 2013) Sugarcane and pineapple production in Hawaii is threatening aquatic life as years of atrazine applications, a pesticide regularly used for corn production too, has run off into rivers, streams, and groundwater sources. Recent reviews by Hawaiian news service Civil Beat found that water testing for the chemical is not tracked currently in the state of Hawaii, despite requirements by U.S. Environmental Protection Agency regulatory limits under the Clean Water Act. Instead, the Hawaii Department of Agriculture almost exclusively relies on label compliance, according to Thomas Matsuda, manager of its pesticide program. Monitoring problems have been compounded by understaffing, with only six inspectors for the state of Hawaii. Not surprising, close examination of atrazine sales records by Civil Beat indicate that the largest buyers of the chemical are Hawaiian seed corn companies Monsanto and Mycogen. Syngenta recently reached a class action settlement in City of Greeneville v. Syngenta Crop Protection, Inc., providing the Kaua’i Department of Water with $6,692.96 for atrazine clean-up expenses. Atrazine is used nationwide to kill broadleaf and grassy weeds primarily in corn crops. A potent toxicant, atrazine is known to be associated with infertility, low birth weight, and abnormal infant development in […]

(Beyond Pesticides, March 6, 2013) The Minnesota Pollution Control Agency announced on March 3rd that state agencies have been ordered by Governor Mark Dayton to stop buying products that contain triclosan, a synthetic, broad-spectrum antimicrobial agent that has become ubiquitous in consumer products ranging from face-washes to fabrics. This ban, which will go into effect in June, comes as the debate over the efficacy and necessity of triclosan intensifies in the Minnesota State legislature. A bill banning triclosan’s use outside of medical settings is expected to be introduced this week, and the legislature conducted a hearing Tuesday on the possible human health and environmental consequences of the chemical. The state government, about 100 school districts, and local governments together currently buy about $1 million worth of cleaning products annually through joint purchasing contracts. Many of these products contain triclosan, but the U.S. Food and Drug Administration concluded in 2010 that products containing triclosan are no more effective than plain old-fashioned soap and water. “There are alternatives, and they are at the same price,” said Cathy Moeger, sustainability manager for the Minnesota’s Pollution Control Agency. “If it has an environmental benefit, why not do it?” Triclosan has been used for over […]

(Beyond Pesticides, March 1, 2013) In a literature review published in Toxicology last week, researchers found that environmental and occupational pesticide exposure was strongly associated with declines in sperm count. Researchers Sheena Martenies, BS, and Melissa Perry, ScD., MHS., determined that of the 17 studies evaluated, 15 of them reported significant associations between pesticides and semen quality. The researchers counted semen quality according to concentration of sperm over an area, their motility and ability to move, as well as their shapes. Researchers targeted studies on DDT, HCH, and abamectin, grouping pyrethroids and organophosphates by class. What they found was striking: almost all the studies reported a decrease in sperm concentration; decreased motility was also reported though less frequently; while morphological changes were not strongly associated in studies””only two indicated any changes to sperm shape. These findings build on a growing body of evidence that pesticide exposure at environmental or occupational levels diminished sperm health. In addition to the U.S. findings,  studies conducted on French, New Zealander, Indian, Tunisian, and Israeli men have all found decline in sperm count. Some studies record a drop by approximately 50% between 1940 and 1990, no small amount. These results might not be surprising as […]

(Beyond Pesticides, February 27, 2013) Last week a U.S. Court of Appeals found that pesticide restrictions to protect endangered salmon and steelhead proposed by the National Marine Fisheries Service (NMFS) in its Biological Opinion (BiOp) were “arbitrary and capricious,” supporting Dow AgroSciences LLC and other pesticide makers’ claims that the restrictions were based on “unsupported assumptions and conclusions.” The BiOp concluded that the pesticides chlorpyrifos, malathion and diazinon, three of the most highly toxic pesticides still in use, pose risks to salmon, steelhead and their habitat. In collaboration with NMFS, the U.S. Environmental Protection Agency (EPA) is tasked with implementation of any recommended pesticide restrictions to satisfy the mandate under Section 7 of the Endangered Species Act (ESA). However, to date, EPA has not taken any actions to implement any of the proposed measures to protect endangered salmon and steelhead, in part due to challenges from industry. Dow AgroScience LLC, Makhteshim Agan of North America, Inc., and Cheminova, Inc. USA first filed a suit in 2009 (Dow Agrosciences v. National Marine Fisheries ), challenging the NMFS’ 2008 BiOp to restrict  chlorpyrifos, malathion and diazinon as being based on numerous unsupported assumptions and conclusions, and faulty analyses. The U.S. District Court […]

(Beyond Pesticides, February 26, 2013) The world’s most commonly used synthetic insect repellent is not  as effective as it once was, according to scientists at the London School of Hygiene and Tropical Medicine. While researchers found DEET to be an effective repellent after an initial application, subsequent rounds of testing mere hours later showed mosquitoes to be unaffected by its presence. The study, published in the journal PLOS One, underlines the need to develop safe, natural, effective alternative preventions to this hazardous chemical. To perform their experiment, researchers took the mosquito species Aedes aegypti, a carrier for dengue and yellow fever, and exposed it to a human arm covered in DEET. A few hours later they repeated the experiment, but this time the mosquitoes largely ignored the presence of the chemical. To find out what caused this to occur, researchers placed electrodes on the antennas of the insects. “We were able to record the response of the receptors on the antenna to DEET, and what we found was the mosquitoes were no longer as sensitive to the chemical, so they weren’t picking it up as well,”   co-author James Logan, PhD told the BBC.  “There is something about being exposed […]

(Beyond Pesticides, February 21, 2013) On February 6, the U.S. Environmental Protection Agency (EPA) released its preliminary volatilization assessment for the registration review of chlorpyrifos, finding that vapor phase chlorpyrifos may be emitted from treated fields at levels resulting in exposure to children and others who live, work, attend school, or otherwise spend time nearby.  In some circumstances, these bystanders may be exposed to chlorpyrifos and/or the transformation product chlorpyrifos-oxon at concentrations that could cause adverse effects. Citing uncertainties, the agency is requesting comments by March 8, 2013 on the potential risks to children and other bystanders from volatilization of chlorpyrifos from treated crops. EPA’s preliminary volatilization assessment is also in response to a petition filed by the Natural Resources Defense Council (NRDC) and the Pesticide Action Network North America (PAN) in 2007, which requested that the agency revoke all tolerances and cancel all registrations for chlorpyrifos. In a letter to NRDC and to PAN dated January 25, 2013, updating these groups on EPA’s response to their September 12, 2007 joint petition regarding chlorpyrifos, EPA stated that, “This assessment represents a significant advancement in the evaluation of pesticide risks, as it will be the first probabilistic assessment of the risks […]

(Beyond Pesticides, February 12, 2013)   Is 2013 the year colony collapse disorder (CCD) begins impacting our food supply? According to the American Bee Journal, almond growers in California may not have access to the honey bee colonies necessary to pollinate this year’s crop. “We need 1.6 million colonies, or two colonies per acre, and California has only about 500,000 colonies that can be used for that purpose. We need to bring in a million more colonies but due to the winter losses, we may not have enough bees,” says Eric Mussen, PhD,  extension apiculturist at the University of California Davis (UC Davis) Department of Entomology. The problem, Dr. Mussen explains, is due to heavy losses this winter and less populous hives overall. Some beekeepers are reporting astonishing winter losses upwards of 90 percent, and in select cases complete colony loss. Honey production in 2012 was one of the worst years in the history of the United States, Dr. Mussen notes. Less honey means less food for overwintering bees, putting increased stress on colonies attempting to fight off the spread of CCD. CCD is the name given to the precipitous decline of honey bee populations around the world beginning in […]

(Beyond Pesticides, February 11, 2013) The U.S. Environmental Protection Agency (EPA) has announced its decision to allow residues of the cancer causing insecticide endosulfan on imported Chinese teas until July 31, 2016. Its decision to provide “additional time to transition to an alternative to endosulfan” raises serious concerns of further exposure to the toxic carcinogen for farmworkers and consumers. In May 2011, EPA proposed to revoke all tolerances for endosulfan, as, “It can pose unacceptable health risks to farmworkers and wildlife and can persist in the environment.” The agency proposed transition time that would allow growers time to adopt alternatives, with the last four uses ending on July 31, 2016. For tea, EPA proposed an immediate revocation, since there is little if any endosulfan used in tea production in the U.S. However, the Chamber of Commerce of the Zhejiang International Tea Industry filed a complaint indicating that it would need five years or less to find feasible alternatives to endosulfan. It also indicated that it was unable to provide comment on the tolerance revocation ruling as the EPA did not provide proper notice to the World Trade Organization. In acknowledging this oversight, EPA will allow endosulfan residues of 24 parts […]

(Beyond Pesticides, February 8, 2013) A recent study conducted at the University of Granada, Spain and published in the Journal Environmental Research proposes a link between exposure to persistent organic pollutants (POPs) in food, air, and water and prevalence of type 2 diabetes in adults, regardless of age, gender, and body mass index. The paper concludes that people with higher concentrations of DDE, the break down product of DDT, are four times more likely to develop type 2 diabetes compared to other participants in the study. Increased rates of type 2 diabetes are also associated with exposure to beta-hexachlorocyclohexane, a break down product of the toxic chemical lindane, which in still allowed for use in agriculture and certain formulations of products used to treat lice and scabies. The study was carried out by analyzing the concentrations of specific POPs in adipose, or fat, tissue of 386 adults undergoing non-cancer-related surgery in Spain. According to one of the authors of the study, Juan Pedro Arrebola, “Human adipose tissue acts as an energy reservoir and has an important metabolic function. However, adipose tissue can store potentially harmful substances, such as POPs.”    The study found that as concentrations of POPs grows in […]

(Beyond Pesticides, February 6, 2013) The U.S. Environmental Protection Agency (EPA) has proposed to register a new insecticide, sulfoxaflor, which the agency has classified as “very highly toxic” to honey bees. Despite efforts underway in Europe to protect bee populations, and continued warnings from beekeepers, EPA is poised to allow another chemical toxic to bees into the environment without proper field studies evaluating long-term effects to bee colonies and with label statements that are impractical and unenforceable. With continuing reports of bee deaths, would sulfoxaflor be yet another bee disaster waiting to happen? Take action and tell EPA not to repeat past missteps and protect pollinators from sulfoxaflor by providing a public comment to EPA.   (see below for sample comments). Last month, EPA opened the comment period for the proposed conditional registration of sulfoxaflor, a new active ingredient, whose mode of action is similar to that of neonicotinoid pesticides -it acts on the nicotinic acetylcholine receptor (nAChR) in insects. Even though it has not been classified as a neonicotinoid, it elicits similar neurological responses in honey bees, with many believing that sulfoxaflor is the new generation of neonicotinoid.  EPA has noted that sulfoxaflor is highly toxic to bees, and […]

(Beyond Pesticides, February 1, 2013) The European Commission announced yesterday its position against the use of neonicotinoid insecticides, pushing nations within the European Union (EU) to impose a two year suspension on their use. The proposal, put forward at a meeting of the Standing Committee on the Food Chain and Animal Health, would restrict the application of neonicotinoids as granules, seed-treatment or spray, on crops that are attractive to bees, particularly, sunflowers, rapeseed, corn, cotton, and cereal crops. Environmental groups say that this decision should signal the way forward for the U.S. Environmental Protection Agency (EPA) to suspend neonicotinoids in the U.S. “It’s a great thing,” said New York beekeeper Jim Doan, “I’m hoping that the EPA follows in their footsteps. While I recognize our government works differently, it says something that the European government has recognized the overwhelming data on the impact of these pesticides.” The announcement comes on the heels of research conducted by the European Food Safety Authority (EFSA) which indicated that three neonicotinoid insecticides””imidacloprid, clothianidin, and thiamethoxam, produced by Switzerland’s Syngenta and Germany’s Bayer, pose an unacceptable hazards to honey bees. In its report released January 16th, EFSA concludes that systemic contamination of neonicotinoid-treated crops, neonicotinoid […]

(Beyond Pesticides, January 31, 2012) A new study finds that a mother’s exposure to pesticides before, during and after pregnancy may increase the risk of infant leukemia diagnosed before the age of two. Researchers in Brazil found that children are twice as likely to develop the rare cancers if their mothers were exposed three months before conception when compared to mothers who reported no exposures. A mother’s exposure at any time to the insecticide permethrin also raised the cancer risk for infants. The results support recommendations for women of reproductive age to minimize their pesticide exposure before and during pregnancy and while breastfeeding, and adds to the growing weight of evidence of the dangers of using synthetic pyrethroid pesticides. The study, entitled, “In utero pesticide exposure and leukemia in Brazilian children less than 2 years of age,” is published in Environmental Health Perspectives. Researchers asked mothers in Brazil about their pesticide exposure three months before pregnancy, while pregnant and three months after pregnancy when they were nursing. The women reported their home, work and agricultural contact with pesticides (at least once) between 1999 and 2007. Pesticide exposures from mothers of 252 children younger than two years old and diagnosed with […]

(Beyond Pesticides, January 29, 2013) A new study has discovered the anti-bacterial chemical triclosan and several of its toxic derivatives in sediment samples taken from freshwater lakes. Research published in the journal Environmental Science and Technology reveals the chemical to be present in increasing concentrations since it was first invented in the 1960’s. The results of this study put increased pressure on lawmakers and cosmetic companies to remove this chemical from consumer products. Beyond Pesticides and other groups, which have petitioned the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA) to remove triclosan from a vast array of consumer products, continues to urge cosmetic companies to take action on the chemical in the face of inadequate regulation to protect human health and the environment. Scientists tested  eight sediment samples from freshwater lakes across Minnesota, including Lake Superior. Bill Arnold, Ph.D.,  co-author of the study and professor at University of Minnesota notes, “We found that in all the lakes there’s triclosan in the sediment, and in general, the concentration increased from when triclosan was invented in 1964 to present day. And we also found there are seven other compounds that are derivatives or degradation products of […]

(Beyond Pesticides, January 28, 2013) Research published Thursday indicates that pesticides widely used on farms are highly toxic to frogs. Researcher Carsten Brühl, Ph.D., at the University of Koblenz-Landau in Germany called the results “alarming” with the potential for “large-scale effects” on amphibians. Two chemicals commonly used in orchards and on grains demonstrated a 100% mortality rate when researchers applied doses recommended on the label, raising serious concerns about the strength of pesticide regulations. The research builds on Brühl’s previous work on the ability of frogs to absorb pesticides through their porous skin, which is necessary for breathing underwater. More importantly, the study highlights the threats that pesticides post to biodiversity. Amphibians are considered the most threatened and rapidly declining vertebrate group, with more than a third of all amphibians listed in the International Union for Conservation of Nature and Natural Resources (IUCN) “Red List” of threatened species. The organization lists loss of habitat, climate change, and disease as the most serious threats to amphibian populations. The scientific community is increasingly recognizing the role of chemical pollutants in amphibian decline. Though sadly, regulatory agencies do not: pesticides are not even required to be tested on amphibians before the pesticide is […]
