(Beyond Pesticides, November 26, 2014) Last week, over 100 scientists from diverse disciplines released a letter citing the growing body of scientific evidence that neonicotinoids and other systemic pesticides harm bees, and called on leaders of President Barack Obama’s Pollinator Health Task Force to quickly take action on pesticides to protect and promote healthy populations of bees and other pollinators. The letter was submitted in response to the recent “listening sessions” hosted by U.S. Environmental Protection Agency (EPA) and the U.S. Department of Agriculture (USDA). These sessions were held by the agencies to  collect public  feedback  on federal efforts on pollinator protection, and the Task Force convened to develop a National Pollinator Health Strategy. In June, the White House issued a Presidential Memorandum directing federal agencies to  join the  Pollinator Health Task Force, led by USDA, to develop pollinator health solutions. The 108 scientists ””whose areas of expertise include entomology, agronomy, ecology, ecotoxicology”” called on Task Force co-chairs, EPA Administrator Gina McCarthy, and USDA Secretary Tom Vilsack, to place a moratorium on the use of neonicotinoid pesticides in the U.S., and increase investment, research and funding for growers to adopt alternatives. In the letter, the scientists note that, “While gaps […]

(Beyond Pesticides, November 20, 2014) A study published in the Journal of Organic Systems this week examined potential connections between the increase in chronic diseases seen within the United States and other parts of the world over the last 20 years and the explosion of glyphosate use, finding a significant correlation between glyphosate use, genetically-engineered (GE) crops, and human health. Glyphosate, one of the most popular weedkillers in both the U.S. and the world, is the active ingredient in Roundup ® ””the leading glyphosate product developed by Monsanto. Known as “Roundup Ready,” GE soybeans, corn, cotton, and other crops have been genetically altered and patented by Monsanto to be glyphosate-tolerant. Whether a crop stems from a Roundup Ready seed or not, glyphosate is used in almost all agricultural areas of the U.S., as well as on an international scale, in conventional, non-organic farming operations. Because of Roundup’s popularity, glyphosate use has skyrocketed, leading to an estimated application of nearly 250 million pounds of the chemical across the U.S. alone and resulting in significant problems of glyphosate resistance and the increased presence of the herbicide in our food and environment. The increased presence of glyphosate has also ushered in independent data […]

(Beyond Pesticides, November 19, 2014) A group of doctors and nurses is urging the Ontario government to ban neonicotinoid pesticides, blamed for the decline of bees and other insect pollinators. As Canada’s first neonicotinoid campaign organized by doctors and nurses, the Canadian Association of Physicians for the Environment and the Registered Nurses’ Association of Ontario say that these pesticides are a “major threat to both nature and people.” The doctors and nurses in Ontario, Canada, now urging the province to ban the pesticides adds to growing pressure on the Ontario government to take action on neonicotinoids (neonics), the insecticide class of chemicals linked to the deaths of bees across Canada and the U.S. Central to the initiative is an advertising buy which starts this week on the Toronto subway system. The ads show an anxious child beneath the caption, ”˜Doctors and Nurses say neonic pesticides hurt our bees and us.’ The Canadian Association of Physicians for the Environment (CAPE) and the Registered Nurses Association of Ontario (RNAO) also plan to meet with the Ontario Environment Minister, Glen Murray, later this year  to urge the government to ban the chemicals. CAPE is the campaign’s main funder, with contributions from David Suzuki […]

(Beyond Pesticides, November 14, 2014) In the face of staggering declines of monarch butterflies, more than 40 leading scientists and 200 organizations and businesses this week urged the Secretary of the Department of the Interior, Sally Jewell, to protect these butterflies under the Endangered Species Act (ESA). These groups and scientists are supporting the formal petition to the U.S. Fish and Wildlife Service (FWS) submitted this summer, which seeks federal protection for monarch butterflies. Forty scientists from around the U.S. and Mexico signed on to a letter requesting protected status for the butterflies and for FWS to recognize the importance of continued research by scientists and citizen scientists in understanding and conserving the monarch butterfly and its habitat. The scientists also request FWS to streamline the permitting process, so that scientific and conservation research and citizen science activities are encouraged rather than deterred by a listing. In a separate letter, over 200 environmental groups and businesses called on FWS to take swift and effective action by granting the monarch butterfly protection as a threatened species under the ESA. Both letters come in support of a formal petition to FWS seeking federal protection for monarchs. The petition was filed in August […]

(Beyond Pesticides, November 10, 2014) According to a new Government Accountability (GAO) report, the U.S. Food and Drug Administration (FDA) does not test food for several commonly used pesticides with established tolerance levels —including glyphosate, one of the most commonly used pesticides in the U.S. This and other disturbing findings documented in GAO’s report,  Food Safety: FDA and USDA Should Strengthen Pesticide Residue Monitoring Programs and Further Disclose Monitoring Limitations,  issued last Thursday, sounds an alarm that GAO began sounding  in the 1980’s in several reports that identify shocking limitations of  FDA’s approach to monitoring for pesticide residue violations in food. GAO sharply criticizes FDA for not using statistically valid methods consistent with Office of Management and Budget (OMB) standards to collect information on the incidence and level of pesticide residues. In fact, GAO states that it “was unable to find publicly available estimates of the overall toxicity or risk associated with the use of agricultural pesticides in the United States.” According to GAO, FDA is testing less than one-tenth of one  percent of all imported fruits and vegetables and less than 1 percent of domestic fruits and vegetables.  The report is also critical of U.S. Department of Agriculture’s (USDA) […]

(Beyond Pesticides, November 7, 2014) Environmental organizations are calling on the Canadian government to  reject the approval of yet another bee-killing pesticide called flupyradifurone. According to Health Canada’s Pest Management Regulatory Agency (PMRA) —responsible for regulating pesticides in Canada— the new pesticide exhibits systemic behavior and “may pose a risk to bees, non-target beneficial arthropods, and freshwater and saltwater invertebrates when used for foliar application.” Additionally, the pesticide “may pose a risk to birds and small wild mammals when used for soybean seed treatment.”  Environmentalists say approval of  flupyradifurone would be irresponsible of PMRA because it would allow yet another chemical with a high potential hazard to bee health into the environment. Environmental groups, including Sierra Club Canada Foundation, David Suzuki Foundation, Pollination Canada, National Farmers Union, Friends of the Earth, and Canadian Association of Physicians for the Environment, have been vocal in expressing their concern about flupyradifurone: “Health Canada has admitted the use of neonicotinoid pesticides threatens bees and other pollinators and has promised a review, but meanwhile wants to open the door to its chemical cousin. Is the government taking the threat of systemic pesticides seriously?” said Lisa Gue, a researcher and analyst at David Suzuki Foundation. Karen […]

(Beyond Pesticides, October 23, 2014) Lawsuit filed against Environmental Protection Agency for approval of 2,4-D use on genetically engineered corn, soy crops in six Midwest states.A coalition of farmers and environmental groups filed a lawsuit to sue the U.S. Environmental Protection Agency (EPA) today on behalf of six Midwest states where a toxic herbicide cocktail called Dow’s Enlist Duo, a blend of glyphosate and 2,4-D, was approved on October 15 for use on genetically engineered (GE) crops. Approved for use on GE corn and soybeans that are engineered to withstand repeated applications of the herbicide, the creation of 2,4-D-resistant crops and EPA’s approval of Enlist Duo is the result of an overuse of glyphosate, an ingredient in Monsanto’s Roundup. The misuse resulted in an infestation of glyphosate-resistant super weeds which can now be legally combatted with the more potent 2,4-D. Dow Chemical has presented 2,4-D resistant crops as a quick fix to the problem, but independent scientists, as well as USDA analysis, predict that the Enlist crop system will only foster more weed resistance. “The toxic treadmill has to stop,” said Jay Feldman, executive director of Beyond Pesticides. “EPA and USDA cannot continue to ignore the history, science, and public […]

(Beyond Pesticides, October 20, 2014) The U.S. Environmental Protection Agency released a report Thursday that soybean  seed treatments with neonicotinoid insecticides provide little or no overall benefits in controlling insects or improving yield or quality in soybean production. While pesticide manufacturer Syngenta has petitioned EPA to raise the allowable levels of another systemic pesticide thiamethoxam on a number of crops, EPA’s report confirms  scientific findings  that these chemical treatments are unnecessary and inefficacious. Widely used neonicotinoids, which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies and by beekeepers  as the major contributing factor in bee decline. The report concludes that not only is there no increase in soybean yield when compared to using no pest control at all, but also the potential benefit of neonicotinoid seed treatment is not likely to be large or widespread throughout the U. S. EPA also found that seed treatments fail to provide protection from target pests during critical times of plant activity, ultimately leading to the assessment that “much of the existing usage on soybeans is prophylactic in nature.” “This report demonstrates, yet again, the need for […]

(Beyond Pesticides, October, 16, 2014) Despite a massive outpouring of public opposition, the U.S. Environmental Protection Agency (EPA) announced yesterday that it has registered Enlist Duo ®, officially putting the rubber stamp of approval on the sale and use of a new wave of genetically-engineered (GE) 2,4-D tolerant crops. Developed by Dow AgroSciences, Enlist Duo ® is an herbicide that incorporates a mix of glyphosate and a new formulation of 2,4-D, intended for use on GE Enlist-Duo ®-tolerant corn and soybean crops. While registration of the herbicide was anticipated by most of the public since the U.S. Department of Agriculture (USDA)’s approval of the Enlist Duo ®-tolerant crops in mid-September, the announcement still comes as a disappointing shock, demonstrating the failings of the U.S. pesticide and agricultural regulatory system to put people and the environment before economic incentives and industry bottom lines. “EPA approval of this herbicide sets a dangerous precedent,” says Jay Feldman, executive director of Beyond Pesticides. “Instead of looking to alternatives, regulators are signaling that the answer to widespread weed resistance is more toxic products that endanger farmworkers and farming communities.” As Beyond Pesticides noted in its comments submitted to EPA in June of this year, the […]

(Beyond Pesticides, October 10, 2014) Many officials are no longer mincing words as they tie the global decline in bee populations with  mounting  evidence pointing to neonicotinoid pesticides. “All the science is not done, but everything that I have before me. . .  suggests to me that this is the biggest threat to the structure and ecological integrity of the ecosystem that I have ever encountered in my life, bigger than DDT, ” said Environmental Commissioner Gord Miller, of Ontario, Canada, as he released his annual report. The Annual Report of the Environmental Commissioner of Ontario, which has been released since 1994, has in recent years found particular scrutiny falling on neonicotinoids. Dichloro-diphenyl-trichloroethane, more commonly known as DDT, was banned in Canada and in the United States in 1972, following a massive environmental movement spurred by Rachel Carson’s Silent Spring, which documented the adverse environmental effects resulting from the indiscriminate use of pesticides. Mr. Miller called bees the “canary in the coal mine” on neonicotinoids, and said the impact of the pesticides is “clearly more wide scale” in the ecosystem. Neonicotinoids  are chemically similar to nicotine and are pesticides that are toxic to a broad range of insect pests. They […]

(Beyond Pesticides, October 8, 2014) After headliners like genetically engineered (GE) Roundup-Ready corn and soybeans failed to deliver on claims of decreased pesticide use and environmental sustainability, instead leading to the rise of “superweeds,” the U.S. Department of Agriculture approved more dangerous, 2,4-D-resistent versions   shortly after. Now after the predictable failure of Roundup-Ready cotton, USDA is set to approve dicamba-tolerant GE cotton, coming soon to a t-shirt near you.   Feeling a bit itchy now? Join us in telling USDA the solution to “superweeds” is NOT more GE crops and increased herbicide use! Act by October 10, at midnight! USDA’s proposal to deregulate and allow into the environment yet another GE variety will inevitably lead to damaging effects on non-GE crops, native plant species, and environmental biodiversity. USDA acknowledges that the purpose of dicamba-tolerant cotton “is to provide growers with an additional in-crop weed management option to manage [glyphosate resistant] broadleaf weed species,” but introducing crops resistant to other chemical technologies like dicamba may provide short-term relief from resistant weeds, but is not a long-term, sustainable solution to burgeoning weed resistance. This current proposal also includes dicamba-tolerant soybean, as well as a stacked tolerance to the herbicide glufosinate. Contrary […]

(Beyond Pesticides, October 1, 2014) Just after announcing a close to its investigation into the illegal presence of genetically engineered (GE) wheat in Oregon, finding it to be an “isolated  incident,”  the U.S. Department of Agriculture (USDA) opened a new investigation into another incident of unauthorized release of  GE wheat, this time  detected in Montana. This new report highlights the contamination threat that these materials pose to farmers and the environment, as well as the government’s failure to recognize the pervasive and persistent nature of GE contamination. According to USDA, on July 14, 2014 it was notified that suspected GE wheat had been discovered growing at the Montana State University’s Southern Agricultural Research Center (SARC) in Huntley, Montana, where Monsanto and researchers grew GE wheat as part of field trials between 2000 and 2003. Testing of the samples by a USDA laboratory confirmed that the wheat is genetically engineered to resist Roundup. The agency states that its ongoing investigation is focusing on why GE wheat was found growing at the research facility location. Currently, GE wheat has not been deregulated by USDA, unlike several other GE crops (corn, soybean, sugarbeets). This means that any experimental use of GE wheat must […]

(Beyond Pesticides, September 23, 2014) A new study finds that the increasingly common use of treated wastewater on food crops can result in contamination from chemicals like DEET, triclosan, and pharmaceutical drugs. The study, titled “Treated Wastewater Irrigation: Uptake of Pharmaceutical and Personal Care Products by Common Vegetables under Field Conditions” and published in Environmental Science & Technology,  measures levels of 19 commonly occurring pharmaceutical and personal care products (PPCPs) in eight  types of vegetables irrigated with treated wastewater under field conditions. The analytes studied include compounds that are commonly detected in treated wastewater, including 16 pharmaceuticals (acetaminophen, caffeine, meprobamate, atenolol, trimethoprim, carbamazepine, diazepam, gemfibrozil, and primidone) and three  personal care products (DEET, triclosan, and triclocarban). The vegetable species included in the  study are carrot, celery, lettuce, spinach, cabbage, cucumber, bell pepper, and tomato, which were included because they are often consumed raw by people and are also among the most important cash crops in arid and semi-arid regions, such as southern California, where there has been a rapid increase in irrigation with treated wastewater. The study points to water shortages in many parts of the world and the U.S. as factors contributing to the increase in use of recycled […]

(Beyond Pesticides, September 19, 2014) The pesticide treadmill continues to turn with the U.S. Department of Agriculture’s (USDA) recent approval this week of three 2,4-D-tolerto ant corn and soybean crops, developed by Dow AgroSciences. Some growers have been pushing for the new Enlist crops in order to combat the rapid proliferation of glyphosate-resistant weeds. The use of glyphosate, the active ingredient in Monsanto’s Roundup formulation, on genetically-engineered (GE) crops has proven to be an abject failure due to widespread weed resistance. So widespread is this resistance that the U.S. Environmental Protection Agency (EPA) has  granted an emergency use exemption  for fluridone, which does not have registered uses in agriculture.  More recently, Texas regulators requested the use of propazine to combat glyphosate-resistant Palmer amaranth, or pigweed, which EPA recently denied,  citing risks to drinking water and other hazards.   Even though the agency denied the emergency use application, it accepted the argument put forth by the Texas Department of Agriculture that  glyphosate-resistant weeds in three million acres of herbicide-tolerant cotton constituted an  “urgent non-routine situation.”  Beyond Pesticides argued to EPA that the weed resistance in  herbicide-tolerant cropping systems is very predictable and has become routine, thus disqualifying states from using the […]

­ ­ ­(Beyond Pesticides, September 17, 2014) DuPont agreed to pay the U.S. Environmental Protection Agency (EPA) $1.853 million to settle charges from the agency that the chemical giant’s herbicide product ImprelisTM was responsible for killing and damaging thousands of acres of spruce and pine trees in 2011. On Monday, EPA filed a Consent Agreement and Final Order against DuPont for violations of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) for selling and distributing its pesticide product -ImprelisTM herbicide. EPA contends that DuPont failed to submit in a timely manner  field trial studies indicating potential ecological adverse effects from the use of Imprelis. In 2011, in what some say was one of the biggest disasters of its kind, Norway spruce and white pine tree damage and deaths were reported throughout the Midwest, in East Coast states, and as far south as Georgia. It was determined that Imprelis, marketed as a “low environmental impact” pesticide, was applied during the spring to control weeds on lawns and other landscapes in the vicinity of the non-target evergreen trees. Imprelis, whose active ingredient is the potassium salt of aminocyclopyrachlor, was conditionally registered by EPA in September 2010, in a regulatory process reminiscent of […]

(Beyond Pesticides, September 4, 2014) Beekeepers in Ontario, Canada are tired of losing bees and have decided to take matters into their own hands by filing a class action lawsuit against two makers of neonicotinoids. According to The Globe and Mail, the lawsuit alleges that Syngenta and Bayer CropScience were negligent in the design, sale, manufacture, and distribution of neonicotinoid pesticides and this negligence caused the plaintiffs, Sun Parlor Honey and Munro Honey, to suffer $450 million in damages. These alleged damages are based on losses from damaged or lost bee colonies, decreased honey production, lost profits, and unrecoverable costs ””all because of neonicotinoids. Neonicotinoids are chemically similar to nicotine and are pesticides that are toxic to a broad range of insect pests. They are also known as systemic pesticides, which are pesticides that spread throughout the entire plant structure, making everything from roots to pollen toxic to organisms that come in contact with it. As a result of neonicotinoids systemic nature, pre-treatment practices, and other factors these dangerous pesticides have been linked to the global disappearance of honey bees and other non-target organisms, such as earthworms, birds, and aquatic invertebrates. For honey bees, the impacts have been astounding, with […]

(Beyond Pesticides, September 2, 2014) U.S. Representative Henry Waxman (D-Calif.) sent a letter to the U.S. Environmental Protection Agency (EPA) last week asking them a poignant question: Why didn’t the human health risk assessment of Dow’s newest 2,4-D-based herbicide apply the ten-fold safety factor required by national law to protect children and infants? The question is a good one and events leading up to it began back in April 2014, when EPA opened up a public comment period for Dow AgroSciences’s application to expand the use of its 2,4-D choline salt herbicide, known as Enlist Duo ®, on 2,4-D-tolerant corn and soybeans. This application was the next step in ushering in a new wave of genetically-engineered (GE) crops sought to replace the quickly waning glyphosate-resistant or Roundup Ready ® varieties. As EPA described on its Enlist-Duo ® webpage, “Weeds are becoming increasingly resistant to glyphosate-based herbicides and are posing a problem for farmers. If [the Enlist Duo ® application is] finalized, this action would provide an additional tool to reduce the spread of glyphosate resistant weeds.” In other words, because of the overuse of glyphosate on GE glyphosate-resistant crops and the resulting development of weeds across the U.S. showing resistance […]

(Beyond Pesticides, August 29, 2014) Environmentalists issued a legal petition to the U.S. Fish and Wildlife Service on Tuesday calling for the protection of the monarch butterfly as a threatened species under the  Endangered Species Act (ESA). Monarch butterflies, a striking and familiar symbol of beauty and nature in the U.S., have had their population decline by a staggering 90 percent in the past two decades alone, most likely due to a significant loss of habitat of more than 165 million acres – an area about the size of Texas -as well as nearly a third of their summer breeding grounds. Part of the decline of monarch butterflies  stems from the loss of milkweed, a native plant where the butterflies lay their eggs and is their main food source. Although little use to farmers, milkweed is an important plant to butterflies, wasps, and bees. A recent study attributed the disappearance of milkweed plants primarily to the use of genetically-engineered (GE) corn and soybean crops. The widespread adoption of GE agriculture and the ever-growing use of herbicides are contributing extensively to the loss of milkweed areas. Scientists also point to the prolific use of herbicides in the Midwest eliminating these plants, […]

(Beyond Pesticides, August 8, 2014) Despite the continued documentation of weed resistance all over the United States, as well as the world, another line of herbicide-tolerant crops developed by Monsanto is currently in the pipeline awaiting likely approval by U.S. regulators. The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) released a draft environmental impact statement (EIS) on Tuesday, which, according to regulators, will pave the way for the approval of new  genetically modified cotton and soybean plants tolerant to a mixture of the herbicides glyphosate and dicamba. Monsanto’s new soybean and cotton crops were developed to withstand their new herbicide formulation, called Roundup Xtend, which combines the pesticides dicamba and glyphosate. The “Roundup Ready Xtend crop system” was developed to curb the proliferation of millions of acres of weeds that have grown resistant to Monsanto’s glyphosate-based Roundup, which has been used on the company’s biotech corn, soybeans, and cotton. Weed resistance due to cropping systems dependent on herbicides has been documented for years, making APHIS’ conclusions in the EIS all the more alarming. A report that Beyond Pesticides published 12 years ago, “The Environmental Risks of Transgenic Crops: An Agroecological Assessment is the failed pesticide […]

(Beyond Pesticides, July 25, 2014) A new U.S. Geological Survey (USGS) study published yesterday found neonicotinoid pesticides persistent and prevalent in streams throughout the Midwestern United States. The study is the first to investigate the presence of neonicotinoids on a wide-scale level in the Midwest. While neonicotinoid use has increased throughout the country, the Midwest in particular has seen a dramatic increase over the last decade. The use of clothianidin, one of the chemicals studied, on corn in Iowa alone has approximately doubled in just two years, from 2011 and 2013. Neonicotinoids are chemically similar to nicotine and are pesticides that are toxic to a broad range of insect pests. They are also known as systemic pesticides, which are pesticides that spread throughout the entire plant structure, making everything from roots to pollen toxic to organisms that come in contact with it. As a result, neonicotinoids have been linked to the global disappearance of honey bees and other nontarget organisms, such as earthworms, birds, and aquatic invertebrates. USGS scientist Kathryn Kuivila, Ph.D., stated, “Neonicotinoid insecticides are receiving increased attention by scientists as we explore the possible links between pesticides, nutrition, infectious disease, and other stress factors in the environment possibly […]

(Beyond Pesticides, July 24, 2014) Last week, the U.S. Environmental Protection Agency (EPA) denied an emergency application to use a hazardous pesticide, propazine, on 3 million acres of Texas cotton fields, after groups representing environmental, public health, and organic farm interests urged the agency to reject the request based on environmental effects and the predictable nature of the weed resistance to currently used chemicals. Despite determining “that an urgent and non-routine condition exists for Texas growers” when certain weed-densities are reached, EPA’s primary reasons for denying the application focused on health and environmental concerns of the pesticide. As EPA explained, “When conducting human health risk assessment for new use the Agency must first consider the risk profile for currently registered uses and determine if an additional use can be added to the cup.” This aggregate risk assessment is required under the Food Quality Protection Actand in the case of propazine, EPA found that “drinking water estimates suggest that risks from drinking water alone may lead to unacceptable risks . . . .” “While we disagree with the EPA that this meets any of the criteria for emergency exemption, we applaud the EPA for putting the health of people and the […]

(Beyond Pesticides,  June 27, 2014) The Environmental Protection Agency (EPA) is considering a  request  by Texas regulators to allow the use of a controversial herbicide, propazine, to battle Palmer amaranth, a glyphosate-resistant “super weed” that has been plaguing growers of genetically engineered (GE) herbicide-tolerant cotton in the state. Propazine, an active ingredient in Milo-Pro, would be sprayed on up to 3 million acres, which amounts to approximately half of the state’s estimated crop acreage for this season. As currently proposed, the maximum amount of product to be applied would be 70,314 gallons. The Texas Department of Agriculture, on behalf of  chemical-intensive GE cotton growers,  asked EPA last month for an exemption to permit growers to spray fields with the herbicide this summer in order to control this highly invasive plant, also known as pigweed. Pigweed can grow up to 3 inches a day and is one of many plant species that has developed a resistance to  glyphosate, a systemic herbicide found in Roundup that has become one of the most widely used pesticides on the market.  Public comments are due by July 3, 2014. The occurrence of super weeds coincides strongly with the use of toxic herbicides on genetically engineered […]
