(Beyond Pesticides, February 24, 2012) On Wednesday, February 22, the Connecticut General Assembly’s Planning and Development Committee held a hearing to consider a bill that would repeal the state’s ban on toxic pesticide use on school grounds by allowing their use as part of a so-called “integrated pest management” (IPM) system. If you live in Connecticut, you can take action to fight this bill and preserve the health of school children. Current state law, adopted in 2005 and amended in 2007 and 2009 to cover facilities from day care centers up through grade 8, prohibits pesticides on playgrounds and playing fields at schools (except under emergency situations), allowing instead for non-toxic pest and fertility management. The bill currently under consideration, HB 5155, would repeal the ban, making pesticide use allowable as part of an IPM program as defined by any number of a range of bureaucratic offices. Although IPM can be a helpful tool in the transition from a pesticide-intensive to a non-toxic management system, it makes no sense to weaken an already strong standard aimed at protecting the health of children. The effort to adopt such a system through passage of HB 5155 is being led by public works […]

(Beyond Pesticides, February 23, 2012) A new study finds organic farming practices in strawberry production result in much greater pollination success than chemical-intensive methods. Researchers also determined that this effect was apparent within just two to four years of conversion to organic, suggesting that there is not a significant lag time before pollination benefits are seen after adopting organic farming practices. The study, led by Georg Andersson of Lund University in Sweden, adds to a growing body of research that highlights the necessity of switching to organic agriculture. Pollination of insect pollinated crops is correlated with pollinator abundance and diversity. Since organic farming has the potential to mitigate negative effects of agricultural intensification on biodiversity, it may also benefit crop pollination, but direct evidence of this has so far been lacking. Researchers speculate that this effect may be due to an increase in insect pollinator abundance and/or diversity. The researchers evaluated the effect of organic farming on pollination of strawberry plants focusing on whether (1) pollination success was higher on organic farms compared to conventional farms, and (2) there was a time lag from conversion to organic farming until an effect was manifested. The results “suggest that organic farming could […]

(Beyond Pesticides, February 22, 2012) Researchers have found high levels of endosulfan, a highly toxic organochlorine pesticide, in the bone marrow of children, including those suffering from hematological malignancies (blood cancers) in areas using the pesticide. Children who have endosulfan in their bone marrow have 7.5 times more risk of developing blood-related cancer compared to those with no detectable pesticide in the bone marrow. While the findings are based on research in India, the insecticide is still used in the production of dozens of crops in the U.S., even though EPA found that exposure to the chemical exceeds the agency’s acceptable risk criteria and announced in 2010 a six-year negotiated phase-out plan with industry that stretches from 2012 to 2016. Following a lawsuit filed against the U.S. Environmental Protection Agency (EPA) in 2008, which cited EPA’s glaring omission in not considering risks to children, EPA announced in 2010 that it would, instead of stopping exposure to a known hazard immediately, phase-out over a six year period all uses of endosulfan in the U.S. Rather than regulating a stop use, EPA astounded many in the environmental and public health community by negotiating a long phase-out agreement with manufacturers that allows some […]

Beyond Pesticides, February 21, 2012) Last week, the Monterey County Board of Supervisors urged California Governor Jerry Brown to reconsider the state’s approval of the carcinogenic fumigant methyl iodide. Monterey County, one of the largest agricultural counties in California, joins Santa Cruz County in mounting pressure to re-examine the controversial decision to approve the toxic chemical as a replacement to the ozone-depleting methyl bromide. This news comes at the heels of the announcement earlier this month that Gov. Brown appointed Brian Leahy, a former organic farmer and the former assistant director at the California Department of Conservation, to head the state Department of Pesticide Regulation (DPR). According to The Californian, agricultural interests present asked County Supervisors to take no action. However, with dozens of local farm workers in attendance pleading their case, the board passed the resolution on a 4-1 recommending that Gov. Brown take another look at the fumigant. Methyl iodide is known to cause miscarriages, thyroid dysfunction, and cancer, and is applied to crops like strawberries and peppers. It was approved by California state pesticide regulators in December as an alternative to methyl bromide, an ozone-depleting chemical being phased out under international treaty. In 2007, EPA fast-tracked the […]

(Beyond Pesticides, February 17, 2011) Beyond Pesticides is urging the U.S. Environmental Protection Agency (EPA), during a public comment period (closing February 23) on its review of the neonicotinoid pesticide, clothianidin, to take swift action to cancel the chemical’s registration. Groups are joining together with comments to EPA, citing the extensive science that shows clothianidin’s toxic effects on honey bees. Beyond Pesticides has drafted comments that it will submit to EPA outlining serious concerns regarding clothianidin. The agency is accepting public comments through February 21, 2012. Tell EPA that because this pesticide is toxic to honey bees and wild pollinators, and has not been properly evaluated in field studies as required it should be banned. Submit comments directly to the EPA docket or sign-on to Beyond Pesticides’ comments. Clothianidin is in the neonicotinoid family of systemic pesticides, which are taken up by a plant’s vascular system and expressed through pollen, nectar and gutation droplets from which bees forage and drink. Scientists are concerned about the mix and cumulative effects of the multiple pesticides bees are exposed to in these ways. Neonicotinoids are of particular concern because they have cumulative, sublethal effects on insect pollinators that correspond to symptoms of honey […]

(Beyond Pesticides, February 16, 2012) Newly released data indicates that more than 40% of American farmers who planted certain varieties of genetically engineered (GE) corn in 2011 failed inspections to verify compliance with mandatory management practices to prevent insect resistance. The farmers involved planted corn varieties that are genetically engineered to express toxins that kill western rootworm. The toxins are derived from Bacillus thuringiensis (Bt), a naturally occurring soil bacterium that when used in non-genetically engineered forms is an important pesticide for organic and sustainable farmers. The non-compliant farmers were specifically cited for failure to establish adequate refuges of non-Bt corn on their farms that the U.S. Environmental Protection Agency (EPA) has determined are necessary to prevent the western rootworm from developing resistance to all forms of Bt. Originally reported on February 9, the results are derived from GE Bt seed suppliers who are required to report refuge data to EPA. As a condition of registering Bt seed varieties as pesticides, EPA requires that farmers using them also plant an appropriately-sized refuge of non-Bt varieties adjacent to the genetically engineered crop. In theory, western rootworms that develop resistance to Bt through constant exposure to the toxins in the genetically engineered […]

(Beyond Pesticides, February 15, 2012) California mosquito control agencies are charging that new NPDES permitting regulations would eliminate West Nile virus fogging and jeopardize public health. In response, the state of California has proposed to scale-back pesticide regulations, easing rules on fumigating adult mosquitoes. This is in spite of the high risk for further degradation of already contaminated surface waters in the state, and contrary to the stipulations and protections set out in the Clean Water Act. The current federal National Pollutant Discharge Elimination System (NPDES) permit, which recently went into effect after much resistance from the pesticide and agriculture industry and intensive lobbying efforts in Congress, does not authorize the discharge of biological and residual pesticides or their degradation by-products to waters of the U.S. that are impaired by the same pesticide active ingredients or any pesticide in the same chemical family. ”˜Impaired waters’ are polluted waters, i.e. those waters not meeting water quality standards pursuant to section 303(d) of the Clean Water Act (CWA). The NPDES permit is authorized under the CWA to require pesticide applicators to apply for permits before applying pesticides on or near surface waters. This process involves keeping records of pesticides used and monitoring […]

(Beyond Pesticides, February 14, 2012) A French court has found U.S. chemical giant Monsanto Co. guilty of pesticide poisoning in the case of a French farmer who became ill after exposure to one of the company’s herbicides, according to Reuters. The case is significant in that it sets precedent for other cases alleging pesticide poisoning or negligence in reporting of potential effects on human health resulting from pesticides. The court has said it will seek an expert opinion regarding the farmer’s losses in order to determine the appropriate amount of damages he should be rewarded. The case stems from an incident in which the farmer, Paul Francois, inadvertently inhaled Monsanto’s Lasso pesticide when cleaning his sprayer tank on his farm in southern France in 2004. He then began experiencing memory loss, headaches, and stammering, among other neurological problems. This led to his decision to file suit against Monsanto, asserting that the company did not provide adequate warnings on the product label that would indicate these symptoms could result from exposure. The court agreed with Mr. Francois, stating that, “Monsanto is responsible for Paul Francois’s suffering after he inhaled the Lasso product … and must entirely compensate him,” according to Agence […]

(Beyond Pesticides, February 10, 2012) Federal District Court Judge Nancy Buchwald heard oral arguments on January 31 on a pre-trial motion filed by Monsanto to dismiss a lawsuit filed against it by the Public Patent Foundation (PUBPAT) on behalf of family farmers, seed businesses, organic agricultural organizations, and environmental groups. The case, Organic Seed Growers & Trade Association, et al. v. Monsanto, challenges Monsanto’s patents on genetically modified seed. The suit was originally filed on behalf of 60 plaintiffs on March 29, 2011, with 23 new plaintiffs, including Beyond Pesticides joining on June 1. The 83 plaintiffs now involved in the suit represent a combined membership in excess of 300,000 people. The plaintiffs in this case are suing preemptively to protect themselves from being accused of patent infringement should they ever become contaminated by Monsanto’s genetically engineered seed, something Monsanto has done to others in the past. “We were very pleased that the court granted our request to have oral argument regarding Monsanto’s motion to dismiss our case today,” said Daniel Ravicher, PUBPAT Executive Director and lead lawyer for the plaintiffs. “The judge graciously permitted both parties to raise all the points they wished in a session that lasted over […]

(Beyond Pesticides, February 9, 2012) Consumer groups submitted a formal petition on Tuesday asking the Food and Drug Administration (FDA) to classify and evaluate AquaBounty’s “AquAdvantage” genetically engineered (GE) salmon and all of its components as a food additive. Currently FDA’s review process classifies the GE salmon as a new animal drug, which the petitioners find insufficient to protect public health. The groups, Center for Food Safety, Food & Water Watch, and Consumers Union say that the agency is required by law to review the GE salmon under a more rigorous process for food additives which offers greater protection. The AquAdvantage salmon would be the first GE animal meant for human consumption. “The data FDA has on GE salmon, which were supplied by Aquabounty, are incomplete, biased, and cannot be relied upon to show that the GE salmon is safe to consume,” said Food & Water Watch Executive Director Wenonah Hauter. “Aquabounty’s own study showed that GE salmon may contain increased levels of IGF-1, a hormone that helps accelerate the growth of the transgenic fish and is linked to breast, colon, prostate, and lung cancer.” The potential health risks of GE salmon, the groups warn, are no different from a […]

(Beyond Pesticides, February 8, 2012) The U.S. Environmental Protection Agency missed a deadline to release federal guidelines on the dangers of excess dioxin chemicals in the food supply and environment, giving ammunition to critics who are urging the agency to change course. EPA was scheduled to release standards in January 2012 that would for the first time set a maximum human-exposure level for dioxins. The delay comes amid criticism and pressure by food and chemical industries that argue the guidelines are too strict. The January 31, 2012 cut-off was part of a reassessment process that has stretched out for 20 years, but the agency has promised to finalize its guidelines “as expeditiously as possible,” although it gave no new deadline. In August 2011, EPA announced a plan for moving forward to complete the dioxin Reanalysis, Volume 1, which is to contain an evaluation of all the scientific literature on dioxin dose-response, including information published since the release of a previous draft Reassessment, and post it by the end of January 2012. EPA was then to post Volume 2 of the Reanalysis soon thereafter. These efforts have been met with resistance from the American Chemistry Council, the International Dairy Foods Association, […]

(Beyond Pesticides, February 7, 2012) The U.S. Department of Agriculture’s (USDA) National Organic Program (NOP) is accepting public comments until April 6, 2012 on a National Organic Standards Board (NOSB) proposal to begin phasing out the use of the synthetic methionine, with a reduction in the current allowable level. Methionine is required for proper cell development and feathering in poultry and has been added in synthetic form to organic poultry feed since the inception of the National Organic Standards under the Organic Foods Production Act (OFPA). Synthetic methionine was officially added to the National List of Allowable Synthetic substances in 2003. Beyond Pesticides and others believe that synthetic methionine should not be used in organic poultry operations and support the NOSB use reduction and phase-out. Naturally-occurring methionine is found in plants and insects that poultry once consumed on the farm (and still do in some operations). Conventional and medium to large scale organic agricultural practices, which raise poultry primarily indoors, have limited the amount of natural methionine available in the birds’ diets. However, the new organic livestock standards adopted at the Fall 2011 NOSB meeting will improve outdoor access for poultry and other livestock, at least partially addressing this issue. […]

(Beyond Pesticides, February 6, 2012) The Clif Bar Family Foundation announced that it has awarded the first fellowships in organic plant breeding ever granted in the United States. Funded through its organic seed initiative, known as Seed Matters, the foundation provided $375,000 to fund three Ph.D. fellowship students for five years in organic plant breeding. The first fellowship recipient has begun working at the Washington State University Mount Vernon Campus and the two other recipients will begin in fall 2012 at the University of Wisconsin-Madison and Washington State University Pullman. As with every agricultural production system, seed is of fundamental importance to organic farmers. However, seed issues in organic agriculture remain especially challenging because of the extremely limited resources that have been dedicated to research and commercial distribution of seeds appropriate for certified operations. For example, the United States Department of Agriculture (USDA) organic certification standard s require that farmers select seed varieties adapted to site-specific conditions including resistance to prevalent pests, weeds, and diseases. However, publicly funded plant breeding programs to develop such locally adapted varieties has decreased dramatically over the past several decades and until very recently none of the funding was dedicated to organic systems. Additionally, the […]

(Beyond Pesticides, February 3, 2012) A new study recently published in the Journal of Integrated Pest Management (JIPM) shows that from 2003 to 2008 the use of insecticide active ingredients was reduced by about 90% in University of Florida (UF) housing buildings after an Integrated Pest Management (IPM) program was implemented. The results of the study show that pest pressure was effectively managed throughout this period as well. These findings demonstrate that IPM can be an effective management tool for institutional pest problems, confronting pests while reducing human exposure to dangerous chemicals. IPM is a systematic approach to managing pests based on long-term prevention or suppression by a variety of methods that are cost effective and minimize risks to human health and the environment. The goal of urban IPM is to manage pests primarily by prevention and elimination of their access to food, water and harborages, exclusion techniques that seal entryways, as well as changes in human behavior. Low-toxicity insecticides were used only when necessary. In their article “Advancement of Integrated Pest Management in University Housing,” the JIPM authors find that the IPM program helps to virtually eliminate the use of hydramethylnon, borate, desiccants, organophosphates, fipronil, and pyrethroids, and they […]

(Beyond Pesticides, February 2, 2011) Beyond Pesticides has partnered with the Just Label It (JLI) campaign, which is made up of a broad-based coalition of 460 partner organizations demanding that consumers have the right to know what is in our food. The campaign has already generated over a half-million consumer comments in support of a petition which calls for food that is produced with genetically engineered (GE) ingredients to disclose this information on the label. The petition was filed with U.S. Food and Drug Administration (FDA) and written by attorneys at the Center for Food Safety. Sign the petition and submit your comments at www.justlabelit.org/takeaction. Beyond Pesticides’ goal is to push for labeling as a means of identifying products containing GE ingredients in an effort to sway consumer demand. The European Union, Japan, Australia, Brazil, Russia, and China, require labeling for GE foods. Recently, the German corporation BASF announced that it would stop developing genetically engineered products targeting the European market, in part due to low consumer demand. Given that a that 93% of Americans support mandatory labeling of genetically engineered (GE) foods, Beyond Pesticides believes that we can have the same impact here as in Europe. In addition, the […]

(Beyond Pesticides, February 1, 2012) Pesticides could be suppressing vitamin D levels in people, leading to deficiency and disease, say scientists. This comes from a new study which discovered that adults with high serum concentrations of organochlorine pesticides, such as DDT, have lower vitamin D levels, further proving that these chemicals have a long-lasting impact on human health. While not widely appreciated, some organochlorine pesticides continue to be used in the U.S., resulting in exposure through our diet, environment, and prescription drugs, while most organochlorine pesticides have been banned in the U.S. and much of the world. Exposure to low doses of organochlorine pesticides has been previously linked to common diseases like type 2 diabetes, metabolic syndrome and cardiovascular disease. Vitamin D deficiency has similarly been associated with a rise in chronic diseases, but the two have been studied separately by researchers in different fields. The study, “Associations between Organochlorine Pesticides and Vitamin D Deficiency in the U.S. Population,” compared serum concentrations of organochlorine (OC) pesticides with serum concentrations of 25-hydroxyvitamin D (25(OH)D), a vitamin D pre-hormone, which is used to assess vitamin D levels in the body. It concludes that background exposure to some OC pesticides can lead to […]

(Beyond Pesticides, January 31, 2012) The Environmental Protection Agency (EPA) has proposed an expansion in pyrethrins/pyrethroid insecticide uses as part of its cumulative risk assessment for this neurotoxic class of chemicals. In the cumulative risk assessment, EPA concludes that pyrethroids “do not pose risk concerns for children or adults,” ignoring a wealth of independent data that links this class of chemicals to certain cancers, respiratory and reproductive problems, and the onset of insect resistance. It went as far as to state that its cumulative assessment supports consideration of registering additional new uses of these pesticides, potentially opening the flood gates for manufacturers to bombard the market with more pyrethroid pesticides, endangering the health of the public. The agency is accepting public comments through February 8, 2012. Tell EPA that it has ignored numerous health effects and that these pesticides do pose unacceptable risks to human health given the availability of alternatives. Submit comments directly to the EPA docket or sign-on to Beyond Pesticides’ comments. In its comments to EPA, Beyond Pesticides states: There are several major concerns and flaws plaguing this cumulative assessment, which therefore does not meet the regulatory burden in fully evaluating synthetic pyrethroids’ effect on public and […]

(Beyond Pesticides, January 30, 2012) The Rodale Institute has published a new technical bulletin containing information and resources to assist farmers in transitioning to diversified organic no-till cropping systems. No-till practices are highly effective for preventing soil erosion and can also decrease labor requirements and fuel use, but they typically depend on heavy pesticide applications to manage weeds in lieu of physical cultivation. This increased dependence on herbicides is unsustainable, contributing to herbicide resistance in certain weeds and increased leaching of pesticides into groundwater due to higher infiltration rates. The technical bulletin outlines the practices that organic farmers can use to capture the benefits of no-till and for conventional farmers to decrease or eliminate the need for herbicides. The technical bulletin contains guidance on using the specialized equipment that enables farmers to move beyond either routine tillage or pesticide applications. The key piece of equipment is a roller-crimper that knocks down the residues from annual crops and crimps them at a standard interval to create a thick vegetative mat into which the next crop is directly planted. The roller-crimper can knock down residues from a cereal crop, such as wheat and oats, or leguminous cover crops including red clover and […]

(Beyond Pesticides, January 27, 2012) The National Research Council (NRC) released a report on Wednesday, finding that, despite extensive investment in nanotechnology and increasing commercialization over the last decade, insufficient understanding remains about the environmental, health, and safety aspects of nanomaterials. Just one day later, a lawsuit was filed in court by the Natural Resources Defense Council challenging approval by the U.S. Environmental Protection Agency (EPA) of a particular nanomaterial, nanosilver, citing the lack of scientific grounding. The suit, filed in the 9th U.S. Circuit Court of Appeals in San Francisco, seeks to block EPA from allowing nanosilver on the market without legally-required data about its suspected harmful effects on humans and wildlife. Starting in December 2011, EPA allowed the company HeiQ Materials to sell nanosilver used in fabrics for the next four years as the company generates the required data on toxicity to human health and aquatic organisms. According to the NRC report, without a coordinated research plan to help guide efforts to manage and avoid potential risks, the future of safe and sustainable nanotechnology is uncertain. The report presents a strategic approach for developing research and a scientific infrastructure needed to address potential health and environmental risks of […]

(Beyond Pesticides, January 26, 2012) The U.S. Environmental Protection Agency (EPA) announced Monday that it is providing a $25,000 grant to the Comite de Apoyo a los Trabajadores AgrĂcolas (CATA) to reduce exposure to pesticides for farm workers in southern New Jersey. CATA, a Latino-led nonprofit organization, will educate migrant farm workers throughout the counties of Atlantic, Burlington, Camden, Cumberland, Gloucester and Salem, New Jersey about the risks of pesticide exposure and how to protect their health during field work. Farm work is demanding and dangerous physical labor. A 2008 study by a National Institute for Occupational Safety and Health (NIOSH) researcher finds that the incidence rate of pesticide poisoning is extremely high among U.S. agricultural workers. An average of 57.6 out of every 100,000 agricultural workers experience acute pesticide poisoning, illness or injury each year, the same order of magnitude as the annual incidence rate of breast cancer in the United States. As a result of cumulative long-term exposures, they and their children are at risk of developing serious chronic health problems such as cancer, neurological impairments and Parkinson’s disease. Southern New Jersey has a large population of migrant farm workers. For the past 20 years, CATA has managed […]

(Beyond Pesticides, January 25, 2012) Apple growers in Michigan are seeking a Section 18 emergency exemption from the U.S. Environmental Protection Agency (EPA) for an unregistered pesticide to curb fire blight on 10,000 acres of apples trees that are susceptible to a deadly disease. Even though Section 18 exemptions from federal pesticide law are only to be used in ”˜emergency conditions,’ this request has been petitioned and granted over the past three years, leading to questions on the of the “emergency” that triggered the section 18 exemption request. In December 2011, the Michigan Department of Agriculture (MDA) asked EPA to grant the use of the antibiotic, kasugamycin, to control streptomycin-resistant strains of Erwinia amylovora, the causal pathogen of fire blight, maintaining that there are no available chemical alternatives and effective control practices. The agency has requested comments until February 6, 2012 at www.regulations.gov, docket number EPA—HQ—OPP—2011—1016. Kasugamycin is not registered for use in the U.S. under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), but has import tolerances for residues on food imported. Fire blight has been on the increase in Michigan orchards and other states for the past few springs due to resistance the disease has to current treatments. […]

(Beyond Pesticides, January 24, 2012) Research published this month in the online edition of the Bulletin of Environmental Contamination and Toxicology finds that the neonicotinoid pesticide imidacloprid contaminates surface waters in agricultural regions. Imidacloprid is a systemic pesticide, meaning it is taken up by a plant’s vascular system and expressed through pollen, nectar, and gutation droplets, and is highly toxic to bees, birds and aquatic organisms. The study, “Detections of the Neonicotinoid Insecticide Imidacloprid in Surface Waters of Three Agricultural Regions of California, USA, 2010—2011,” concludes that imidacloprid commonly moves offsite and contaminates surface waters at concentrations that could harm aquatic organisms following use under irrigated agriculture conditions. Researchers at the California Department of Pesticide Regulation collected 75 surface water samples from three agricultural regions of California and analyzed them for contamination with imidacloprid. Samples were collected during California’s relatively dry-weather irrigation seasons in 2010 and 2011. Imidacloprid was detected in 67 samples (89%); concentrations exceeded the U.S. Environmental Protection Agency’s (EPA) chronic invertebrate Aquatic Life Benchmark of 1.05 ĂŽÂĽg/L (micrograms per liter) in 14 samples (19%). Concentrations were also frequently greater than similar toxicity guidelines developed for use in Europe and Canada. A benchmark is a chemical concentration, specific […]
