Fed To Require Strengthened State Protection from Nonpoint Pesticide Pollution

Beyond Pesticides, December 23, 2013) The Environmental Protection Agency (EPA) and the National Oceanic and Atmospheric Administration (NOAA)  in a  Federal Register notice  has found that the state of Oregon’s program to reduce nonpoint coastal pollution is inadequate. Both federal agencies state that Oregon’s program does not adequately protect streams that provide habitat for Coho Salmon, an endangered species, and drinking water from herbicides that are aerially sprayed by lumber companies. This notice comes just after a recent report was released by Beyond Toxics on the health and environmental problems caused by aerial herbicide application on timber forests near Triangle Lake. EPA and NOAA’s proposed disapproval action of Oregon’s Coastal Nonpoint Program finds that the state has failed to adequately protect certain waterways within the state. Under the Coastal Zone Act Reauthorization Amendments (CZARA) of 1990, states are required to submit an approvable Costal Nonpoint Pollution Control Program to NOAA and EPA. In 1998, federal agencies approved the Oregon Nonpoint Program with conditions that the state meet certain water pollution issues. This proposed disapproval action is part of a settlement of a lawsuit brought by the Northwest Environmental Advocates in 2009, which charged Oregon has failed to meet the conditions […]

Bee-Killing Pesticides Damage Children’s Brain and Nervous System, Says European Authority

(Beyond Pesticides, December 20, 2013) The European Food Safety Authority (EFSA) announced on Tuesday that pesticides linked to honey bee deaths worldwide may also damage human nervous systems ””in particular the brain, and recommended that the European Commission lower the guidance levels of acceptable exposure until more research is conducted. This new determination heightens the call to ban the use of these toxic chemicals in the U.S., following the lead of the European Union (EU). EFSA found that two commonly used chemicals “may adversely affect the development of neurons and brain structure associated with functions such as learning and memory” particularly of children. The recommendation focuses on two chemicals ””acetamiprid and imidacloprid”” in a relatively new class of insecticide called neonicotinoids. Three chemicals in this class were recently placed under a two-year ban in the European Union (EU) for uses on flowering crops known to attract honey bees. The move stems from a recent review of research on rats which found, “Neonicotinoids may adversely affect human health, especially the developing brain.” Researchers who exposed newborn rats to one of these chemicals ””imidacloprid”” found they suffered brain shrinkage, fewer nerve signals controlling movement, and weight loss. Another study on rats found […]

Environmental and Farm Groups Support Beekeepers’ Challenge of Newest Bee-Toxic Pesticide

(Beyond Pesticides, December 19, 2013) Environmental and farm groups, including Beyond Pesticides,  came together to file a legal brief in support of the nation’s major beekeeping associations’ lawsuit against the U.S. Environmental Protection Agency (EPA). The beekeepers, including the Pollinator Stewardship Council, American Honey Producers Association, National Honey Bee Advisory Board, and the American Beekeeping Federation, are requesting that a federal court vacate EPA’s decision to register sulfoxaflor, a new chemical known to be highly toxic to bees and considered in the same chemical class of the controversial insecticides known as neonicotinoids, which have been linked to bee decline. According to the  Friend of the Court (Amicus curiae) brief, filed by the Center for Food Safety on behalf of the organizations, “Scientists have linked the drastic declines in honey bee and other pollinator populations to systemic pesticides, and more specifically, to a category of systemic pesticides known as neonicotinoids.  Sulfoxaflor is a systemic pesticide with the same mode of action as neonicotinoids, that EPA determined is ”˜very highly toxic’ to bees.  EPA’s registration of sulfoxaflor will introduce yet another systemic and highly toxic insecticide into the environment, intensifying the ecological crises of Colony Collapse Disorder (CCD) and other pollinator losses.” […]

Beyond Pesticides’ Decade-Long Campaign Leads FDA to Bar Antibacterial Soaps

(Beyond Pesticides, December 17, 2013) A new rule proposed by the U.S. Food and Drug Administration (FDA) requires manufacturers of antibacterial hand soaps, body washes, and other consumer goods to prove that their products are both safe for long-term use and more effective than regular bar soap in order to remain on the market. This announcement, though long-delayed, represents a positive step towards reining in the unnecessary use of antibacterial chemicals at a time when top-level government scientists at the U.S. Centers for Disease Control and Prevention (CDC) have asserted that we’ve reached “the end of antibiotics.”  With the publication of its article The Ubiquitous Triclosan: A common antibacterial agent exposed  in 2004, Beyond Pesticides began a campaign to ban triclosan because of it cross resistance with antibiotics, endocrine disrupting effects, and lack of benefits. “Numerous studies have shown that antibacterial soaps cause more harm than any of their perceived benefits,” said Nichelle Harriott, staff scientist  at Beyond Pesticides. “For the protection of human health and the environment, we urge the FDA to move quickly to get these products off of the market.” FDA’s new rule, announced Monday, will be open for public comment for 180 days and manufacturers will […]

Unregulated Contaminants Found Widespread in U.S. Drinking Water

(Beyond Pesticides, December 13, 2013) A recent survey conducted by researchers at the U.S. Geologic Survey (USGS) and the U.S. Environmental Protection Agency (EPA) found traces of 18 unregulated chemicals in drinking water from more than one third of U.S. water utilities. Of the 21 total chemicals found, researchers discovered among them 11 perfluorinated chemicals, an herbicide, two solvents, caffeine, an antibacterial chemical, a metal and an antidepressant. Preliminary findings were presented by scientists at an annual toxicology conference held by the Society of Environmental Toxicology and Chemistry last month in Nashville. Federal researchers took samples from 25 U.S. utilities from around the nation who voluntarily participated in the study, providing samples of treated and untreated water. Disturbingly, 18 of the chemicals found are not regulated under the Safe Water Drinking Act, meaning utility companies are not required to treat, limit, or even monitor for their presence. “The good news is the concentrations are generally pretty low,” said USGS research hydrologist Dana Kolpin, PhD. to Environmental Health News. “But,” he continued “there’s still the unknown. Are there long-term consequences of low-level exposure to these chemicals?” While there is a paucity of data on some of the contaminants, regulated chemicals such […]

Maui Third Hawaiian Island to Consider Restricting Pesticides and GMOs

(Beyond Pesticides, December 11, 2013) Following the counties of Kaua’i and Hawaii, Maui Council Member Elle Cochran has introduced legislation (full text available here) that will require disclosure of pesticides and genetically modified organisms (GMOs) in agriculture. In addition, the bill requires buffer zones and a health impact study. The Council Member feels it is important to make permanent a voluntary agreement reached between the Mayor of Maui and Monsanto, according the Associated Press. Monsanto, which has written on similar legislation in the other Hawaii counties, maintains that, “Monsanto is committed to being a good neighbor and responsible business. We have very strict policies and practices in place to ensure we meet all state and federal laws, operate in a responsible and safe manner.” The Maui Farm Bureau has said that these technologies are necessary to grow food for a growing population. Kauai made history in Hawaii and worldwide in November when it enacted a law to force public disclosure of large scale production of experimental genetically engineered organisms and pesticide use. Using the authority vested in local political subdivisions by the state’s constitution, the law seeks to “to establish provisions to inform the public, and protect the public from […]

Flight Attendant Links Airline Insecticide Use to His Parkinson’s

(Beyond Pesticides, December 10, 2013) A former steward for Australian-based Quantas airlines is suing the Australian government claiming that frequent insecticide use in airplane cabins resulted in his Parkinson’s disease diagnosis. Australia is among 49 countries that require pesticide spraying on some or all flights. Pesticide use on flights into the United States is not required, but is permitted under international law. (See here for a breakdown of pesticide use in American-based airlines, and here for information from the U.S. Department of Transportation on pesticide use in aircrafts.) Brett Vollus, former Quantas airline steward, worked for the company for 27 years until this past May when he was diagnosed with Parkinson’s and a malignant brain tumor. “He [my doctor] asked me what I did for living and when I told him he just nodded and said: ‘Another one, I am seeing a lot of you’,” Mr. Vollus said to The Australian. “This is a nightmare that has ruined my life. I am very keen to start a legal action and if it can help others I am happy to lead the way.” This case puts an international spotlight on growing evidence that pesticide use is linked to Parkinson’s disease. Parkinson’s […]

Feds Moves to Dismiss Case Seeking to Protect Children from Pesticides

(Beyond Pesticides, December 4, 2013) The U.S. Department of Justice filed a motion in federal court asking a judge to dismiss a lawsuit alleging that the U.S. Environmental Protection Agency (EPA) has failed to uphold environmental justice protections under civil rights law. EPA previously found that Latino schools in California disproportionately suffer from exposure to pesticides due to spraying near their schools, but has yet to adequately remedy these risks, prompting parents to file a civil rights complaint. The schools are near crop fields where toxic fumigants are routinely sprayed and drift off agricultural fields to the nearby community. More than a decade after Latino parents first filed a civil rights complaint with EPA detailing the dangerous levels of pesticides at Latino public schools throughout California, parents on Aug. 23, 2013 filed a lawsuit against EPA to force the agency to protect the civil rights of hundreds of Latino children. The parent say that  ongoing pesticide monitoring set up by the California Department of Pesticide Regulation (CDPR) has not protected children from excessive exposure to pesticides.  The case argues that the Latino community did not receive due process and that EPA’s agreement with CDPR does not prevent schools from pesticide […]

Start of EU Moratorium on Neonicotinoids Puts Focus on US EPA Inaction

(Beyond Pesticides, December 3, 2013) On Sunday, December 1, 2013 the European Union (EU) took critical steps to protect pollinators from the hazards associated with the use of neonicotinoid pesticides. Despite attempts by agrichemical corporations, including Bayer, and Syngenta,   to delay or reverse the decision, the two-year, continent-wide ban on bee-harming pesticides has gone into effect. However, what’s happening on the other side of the Atlantic is part of a larger story that raises serious concerns for the future of our food. In the United States, the Environmental Protection Agency (EPA), under the direction of Administrator Gina McCarthy, has put forth inadequate label changes that do not protect pollinators. With the support of   over 60 organizations, Beyond Pesticides has helped launch a coalition-based  national advertising campaign to raise awareness of pollinator declines and urge EPA to stop stalling by enacting substantive restrictions on the use of bee-harming pesticides. Go to save-bees.org to lend your support to these efforts. Neonicotinoids, a relatively new class of pesticides, are often used as a seed coating on agricultural crops. Studies have found that honey bees are exposed to high concentrations of neonicotioid pesticides through the dust that is kicked up when coated […]

Broad Coalition Is Building Buzz on Pollinator Decline with National Ad Campaign

(Beyond Pesticides, December 2, 2013) Today, Beyond Pesticides, Center for Food Safety and Pesticide Action Network, supported by Ceres Trust and joined by more than 60 other organizations, launched a national media campaign to bring attention to the severity of pollinator declines due in part to the use of bee-harming pesticides. The campaign launch was timed to coincide with the beginning of the European Union’s two-year moratorium on three of the most potent neonicotinoids, which began yesterday. See the ad here. For action item related to this campaign, go to www.save-bees.org. For more on Beyond Pesticides’ BEE Protective campaign, go to www.BEEprotective.org. As part of the national media campaign, full page ads were released in seven newspapers today, including the New York Times, citing the urgency and impact of bee declines and encouraging the public to call on EPA to take action. “We hope this national media campaign will spur public action to combat this major threat to the environment and to our food system. We must protect bees and other pollinators from these harmful pesticides that EPA has so far failed to safeguard them from,” said Larissa Walker, policy and campaign coordinator for Center for Food Safety.

Oregon Restricts Some Neonicotinoid Pesticide Uses after Bee Kills

(Beyond Pesticides, November 25, 2013) The Oregon Department of Agriculture (ODA) has restricted two pesticide products linked to massive bee die offs experienced in Oregon earlier this year. Both pesticides are neonicotinoid chemicals that are extremely harmful to bees. Though these restrictions are an important step in protecting bee health, the new rules will still not limit all of the uses of these chemicals that can harm pollinators. ODA placed restrictions on dinotefuran and imidacloprid, banning their use  on linden trees, basswood and other trees of the Tilia genus. Pesticide products that contain these active ingredients are now required to have Oregon-specific labels. This is only the second time in the past ten years that ODA has regulated pesticides more strictly than federal standards. These new restriction comes after ODA adopted a temporary rule in June that limited the use of 18 pesticide products that contained diontefuran. That rule was set to expire next month. States and local jurisdictions  have authority under the nation’s pesticide registration law, the  Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), to adopt more stringent pesticide use restrictions than the federal government. However, after the U.S.  Congress rejected proposals to preempt local authority and the Supreme […]

EPA Reluctant to Endorse Chemical Safety Improvement Act

(Beyond Pesticides, November 22, 2013) The U.S. Environmental Protection Agency (EPA) Assistant Administrator of the Office of Chemical Safety and Pollution Prevention, James Jones, testified before the House Subcommittee on Environment and the Economy last week. The subject of Jones’ testimony: EPA’s informal observations on the proposed Chemical Safety Improvement Act (CSIA). Introduced this past April, the CSIA seeks to reform the severely outdated and ineffective Toxics Substances Control Act (TSCA), the nation’s primary chemical safety law. Adopted in 1976, TSCA established an inventory and notification framework to monitor and assess the commercial production and importation of chemicals. Excluding large swaths of chemicals (such as pesticides and drugs) and placing the burden on EPA to demonstrate unreasonable risks to health or the environment, TSCA has done little to protect the public from or enable EPA to restrict the uses of the more than 84,000 chemicals in the marketplace today. As one 2009 Government Accountability Office (GAO) report noted, “Since 1976, EPA has issued regulations to control only five existing chemicals.” Assistant Administrator Jones’s testimony was quick to point out TSCA’s many flaws, including the grandfathering in of 60,000+ chemicals without any kind of testing and EPA’s inability to require testing […]

Climate Change Increases Storm Severity and Toxic Chemical Hazards

(Beyond Pesticides, November 13, 2013) As the world sheds tears from reading the reports of human suffering and looks on in horror at the pictures of devastation caused by Typhoon Haiyan, the debate of whether increased occurrences of super-storms like Haiyan are just over the horizon because of man-made climate change have also taken up residence in the headlines. Coupled by coverage of the 19th session of the Conference of the Parties to the U.N. Framework Convention on Climate Change and the leak of a draft summary of the Intergovernmental Panel on Climate Change’s latest report on the impacts of global warming, the world is clearly paying attention. As the wide array of demonstrated effects and impacts of climate change are discussed on the world stage and world leaders attempt, once again, to create a meaningful plan to mitigate risks and even potentially avoid some of the most extreme threats, an important and even more deadly consequence of climate change lurks in the background: increased toxic chemical exposure. In a collection of studies and scientific reviews released earlier this year in Environmental Toxicology and Chemistry, scientists investigated a wide range of global climate change issues and toxicological impacts on the […]

BASF Sues EU Commission for Restricting Pesticides Harmful to Bees

(Beyond Pesticides, November 12, 2013) On November 6 BASF, a German agrochemical company, took legal action in the General Court of the European Union (EU) to challenge the EU Commission’s decision to restrict seed treatment uses of the insecticide fipronil. BASF joins chemical companies Bayer and Syngenta in challenging the EU’s decision to restrict the use of certain pesticides that are harmful to pollinators. The EU Commission’s decision to restrict the use of fipronil in July came after the Commission’s landmark decision announcing a two-year continent-wide ban  on the neonicotinoid pesticides clothianidin, imidacloprid and thiamethoxam. The pesticides have been linked to the decline in bee populations.  Twenty-three European Union Member States supported the fipronil restriction, two Member States voted against, and three Member States abstained during the standing committee vote. BASF argued that its  legal action against the EU is based on a disproportionate application of the precautionary principle. However, overwhelming scientific evidence supports the position that fipronil is highly toxic to bees. Fipronil, a phenyl pyrazole broad-spectrum insecticide, was first introduced in the U.S. in 1996 for commercial turf and indoor pest control and is highly toxic to bees. A recent investigation reveals that fipronil is responsible for the […]

Increased Risk of Endometriosis Linked to Persistent Pesticides

(Beyond Pesticides, November 7, 2013) A study released this week established a strong connection between endometriosis and exposure to two dangerous pesticides: lindane and mirex. While the results are not surprising given past connections between these pesticides and their endocrine-disrupting effects, this new study, Organochlorine Pesticides and Risk of Endometriosis: Findings from a Population-Based Case-Control Study, is one of the first to examine the association between organochlorine pesticides (OCPs) and endometriosis, one of the most common gynecological diseases, in women in the general population. The study’s authors, Kristen Upson, Ph.D. et al,  explained to Environmental Health Perspectives, “Our study suggests that exposure from extensive past use of environmentally persistent OCPs in the United States, or present use in other countries may impact the health of the current generation of reproductive-age women with regard to a hormonally-mediated disease.” In conducting the study, researchers selected a group of women with surgically-confirmed cases of endometriosis from the greater Pacific Northwest area. This group of women was then divided into four groups, based on the level of pesticide in each woman’s blood. Women in the second-highest exposure group for beta-hexacyclochlorohexane (beta-HCH), a byproduct of lindane, had a 70 percent greater risk of endometriosis than […]

Settlement Will Safeguard Endangered California Frog from Harmful Pesticides

(Beyond Pesticides, November 6, 2013) A federal district court approved a settlement Monday requiring the U.S. Fish and Wildlife Service to better protect California red-legged frogs from seven common pesticides known to be highly toxic to amphibians. The settlement gives the agency two years to prepare “biological opinions” under the Endangered Species Act (ESA) to analyze pesticide use in and near the frog’s aquatic and upland habitats.   A 2006 legal settlement secured by the Center for Biological Diversity (CBD) required the U.S. Environmental Protection Agency (EPA) to assess pesticide impacts on red-legged frogs and to then formally consult with the Fish and Wildlife Service (FWS) under the ESA. The EPA’s assessments found that widespread use of pesticides is likely harming red-legged frogs and the court ordered temporary pesticide use restrictions that remain in effect today. EPA determined that 64 other pesticides are “likely to adversely affect” or “may affect” red-legged frogs. Despite the EPA’s findings, however, FWS and EPA failed to complete the required consultation, resulting in the litigation by CBD that culminated in Monday’s settlement. The court order gives FWS two years to complete biological opinions for seven pesticides: glyphosate, malathion, simazine, pendimethalin, permethrin, methomyl and myclobutanil. This […]

Behavioral and Emotional Problems in Children Linked to Insecticide Exposure

(Beyond Pesticides, November 1, 2013) Insecticides commonly used in homes and schools are associated with behavioral problems in children, according to a recent study by Canadian researchers. The study investigates exposure to pyrethroid pesticides, used in more than 3,500 products, including flea and tick controls, cockroach sprays, and head lice controls. The study, Urinary metabolites of organophosphates and pyrethroid pesticides and behavioral problems in Canadian children, published in the journal Environmental Health Perspectives, raises serious concerns about the impact of pyrethroids, which are increasingly used as a replacement for organophosphates. This study uses data from the Canadian Health Measures Survey (2007-2009), a nationally representative survey, so researchers are able to apply these findings to the entire population of Canadian children. In a previous study among U.S. children, researchers at the National Health and Nutrition Examination Survey (NHANES) examined the metabolites of pyrethroids in children below the age of six. Similarly, they found pyrethroid insecticides in more than 70 percent of the samples, concluding that children had significantly higher metabolite concentrations than those of adolescents. Together these studies demonstrate that exposure is widespread, with real impacts to human health. In the recent study, researchers analyzed organophosphate and pyrethroid metabolites in the […]

Bats Are Not the Real Threat This Halloween

(Beyond Pesticides, October 31, 2013) Bats get a bad rap on Halloween with their image synonymous with blood-sucking vampires; however, the real scary thing about bats is that they are disappearing due to a myriad of threats, including pesticides, habitat destruction, and the horrible white-nose syndrome (WNS), a disease caused by the fungus Pseudogymnoascus (Geomyces) destructans. Researchers are reporting an even bleaker picture, finding very little evidence of what might stop the disease from spreading further and persisting indefinitely in bat caves. The new study, from researchers at the Illinois Natural History Survey at the University of Illinois, found that the fungus can make a meal out of just about any carbon source likely to be found in caves, said graduate student Daniel Raudabaugh, who led the research under the direction of survey mycologist Andrew Miller, Ph.D. The study, Nutritional Capability of and Substrate Suitability for Pseudogymnoascus destructans, the Causal Agent of Bat White-Nose Syndrome is published in PLOS One. “It can basically live on any complex carbon source, which encompasses insects, undigested insect parts in guano, wood, dead fungi and cave fish,” Mr. Raudabaugh said. “We looked at all the different nitrogen sources and found that basically it can […]

Exposure to Atrazine in Combination with Fungus Increases Mortality of Frogs

(Beyond Pesticides, October 29, 2013) Early-life exposure to the herbicide atrazine makes frogs more susceptible to death from chytrid (Batrachochytrium dendrobatidis), a fungal disease implicated in amphibian declines across the globe. The research, Early-life exposure to a herbicide has enduring effects on pathogen-induced mortality, published in the Proceedings of the Royal Society B and led by University of South Florida (USF) biologist Jason Rohr, Ph.D, provides critical information for scientists hoping to stem the global demise of amphibian populations. “Understanding how stressors cause enduring health effects is important because these stressors might then be avoided or mitigated during formative developmental stages to prevent lasting increases in disease susceptibility,” Dr. Rohr explains. Researchers exposed tadpoles to atrazine at levels found in the environment for a period of  six days during the animal’s development, in combination with exposure to chytrid fungus (linked to worldwide amphibian decline), resulted in increased mortality 46 days later. According to the study, “[E]arly-life exposure to atrazine altered growth and development, which resulted in exposure to chytrid at more susceptible developmental stages and sizes, and reduced tolerance of infection, elevating mortality risk at an equivalent fungal burden to frogs unexposed to atrazine. Moreover, there was no evidence of […]

Multi-generational Effects of DDT Linked to Obesity

(Beyond Pesticides, October 28, 2013) Scientists at Washington State University (WSU), in a laboratory study,  determined that exposure to the insecticide DDT ””banned in the U.S. since 1972, but still used today in developing countries for malaria abatement programs””impacts multiple generations, ultimately contributing to obesity three generations down the line. The study, published in the journal BMC Medicine, provides the scientific community with new information on multi-generational impacts of pesticide exposure. Lead researcher Michael Skinner, PhD., professor of biological sciences at WSU, and colleagues exposed pregnant rats to DDT to determine the long-term impacts to health across generations. The study, Ancestral dichlorodiphenyltrichloroethane (DDT) exposure promotes epigenetic transgenerational inheritance of obesity, finds that the first generation of rats’ offspring developed severe health problems, ranging from kidney disease, prostate disease, and ovary disease, to tumor development. Interestingly, by the third generation more than half of the rats have increased levels of weight gain and fat storage. In other words, the great grandchildren of the exposed rats are much more likely to be obese. “Therefore, your ancestors’ environmental exposures may influence your disease development even though you have never had a direct exposure,” the study finds. Previous studies have demonstrated that exposure to […]

New Study Links Neonicotinoids to Bee Virus

(Beyond Pesticides, October 24, 2013) A team of scientists in Italy believe they have found the molecular mechanism through which neonicotinoid pesticides adversely impacts the immune system of honey bees. The team’s experiments suggest that exposure to neonicotinoids results in increased levels of a particular protein in bees that inhibits a key molecule involved in the immune response, making the insects more susceptible to attack by harmful viruses. Though previous studies have indicated that exposure to minute amount of neurotoxic pesticides like neonicotinoids severely impair the immune systems of bees, making them more susceptible to pathogens, the underlying mechanism has was not yet been fully  understood. The study, Neonicotinoid clothianidin adversely affects insect immunity and promotes replication of a viral pathogen in honey bees, is published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS). This work is the latest of several studies to add weight to the urgency of repeated calls from U.S. beekeeper and environmental groups for the Environmental Protection Agency (EPA) to  suspend the use of neonicotinoid pesticides, as the European Commission recently decided this past April. Neonicotinoids, a class of insecticides that includes clothianidin and imidicloprid, are taken up […]

Pesticide Spraying Stopped after Concerned Parents Mobilize

(Beyond Pesticides, October 23, 2013) Ball State University, Indiana has cancelled plans to spray herbicides on the lawns around its K-12 school after objections from parents worried that it would expose their children to toxic chemicals. The university planned to use Trimec 992, a 2,4-D product, but a petition started by parents helped to put a stop to the weedkiller. The spraying was scheduled for last week, the start of the fall break at Burris Laboratory School, a separate K-12 school district overseen by Ball State University. School Principal Cathlene Darragh sent an email to Burris parents last Friday  explaining that  the school decided against the spraying. “We have received a great deal of feedback from parents and the community about possible weed and pest control for the school lawn that was scheduled for this weekend. We have worked with the facilities department to further evaluate the need to spray. Upon further consideration, we have decided to forgo the scheduled spraying.” Parents mobilized after it became known that the school planned to spray Trimec 992, a 2,4-D product on school grounds. 2,4-D, a widely used herbicide in many ‘weed and feed’ lawn care products, is associated with many human and […]

Investigative Report Finds Soaring Pesticide Use and Poisoning Linked to GE Crop Production

(Beyond Pesticides, October 22, 2013) Nearly a week after plant geneticists from the world’s largest agrichemical companies accepted the World Food Prize, an Associated Press (AP) investigation links the effect of their work to soaring pesticide use and resulting health problems.  According to the  AP, the advent of “no-till” farming methods in Argentina with the use of genetically engineered (GE) crops and companion pesticides has caused significant health impacts in farming towns abutting GE fields. Since the introduction of these practices in Argentina by agrichemical companies such as Monsanto, cancer rates have skyrocketed and the number of birth defects has quadrupled. Argentina was an early adopter of GE technology in 1996, when it was billed as the silver bullet to solve world hunger with increased crop  productivity, and improved human and environmental health resulting from decreased pesticide use. The most widely used GE crops, such as Monsanto’s Roundup Ready line of corn and soybeans, allow farmers to apply the herbicide glyphosate during and after seed plantings in order to kill weeds without risk of the main crop dying off.
