(Beyond Pesticides, February 29, 2012) Bees are in trouble –in large part because of pesticides– and policymakers just aren’t acting quickly enough to help them. But backyard gardeners, sideline beekeepers, and ordinary people all over the country have been stepping up. Beyond Pesticides and Pesticide Action Network North America have launched HoneyBeeHaven.org, a site where individuals who are taking matters into their own hands can add their pesticide-free pollinator habitat to the map, while we continue to pressure EPA to protect honey bees and wild pollinators from pesticides. On the website, visitors are encouraged to take the pledge to go pesticide-free and protect bees, and then put your yard, park, or school grounds on the map. It’s easy to do, and will demonstrate the groundswell of citizen support to protect pollinators from pesticides now. Display a Pesticide Free Zone sign to show your neighbors that pesticide-free spaces are important for health and the environment. You don’t need to be a beekeeper or avid gardener to create a safe haven –tucking a few containers of bee-friendly plants on a balcony or front stoop will get you started. Like any other living organism, bees need food, water, and shelter in order to […]

(Beyond Pesticides, February 28, 2012) A study by researchers at the University of Padova in Italy and published in the journal Environmental Science and Technology has confirmed the findings of previous research showing that honey bees are exposed to toxic neonicotinoid insecticides during spring seed planting. Neonicotinoids are known to be highly toxic to honey bees and, yet, are used on millions of acres through North America every year. These findings lend even greater urgency to the need to take these chemicals off the market and ensure the continued survival of honey bees and the essential pollination services that they provide for our food system. Neonicotinoids, including clothianidin, imidacloprid, and thiamethoxam, are most commonly applied by coating crop seeds with the chemical. When these treated seeds are planted, the chemical becomes part of the plants vascular system and stays in the plant for the duration of its lifetime, expressing itself in the pollen. Previously, it had been thought that bees were only exposed to these chemicals through pollen and water droplets from treated plants, which would occur later in the season once the plants had grown and bloomed. However, the Italian study shows that bees are actually exposed to high […]

(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 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 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 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 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 μg/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 […]

(Beyond Pesticides, January 19, 2012) Although organic farming and land management continue to grow, policies to protect people from pesticides are threatened in the Northeast and around the country.

(Beyond Pesticides, January 18, 2012) Given the persistent wariness of genetically modified organisms (GMOs) in Europe, Germany’s BASF will stop developing new products targeting the European market. The group announced on January 16 that it plans to refocus its activities in the sector on more receptive regions. Unfortunately, this means BASF will redouble its efforts in the U.S. to develop new GMO products, leading to public and environmental health concerns in this country. In a statement, a BASF representative announced, “Biotechnologies are not accepted enough in many parts of Europe by the majority of consumers, farmers and political leaders. That is why it does not make sense economically to continue to invest in products aimed exclusively at this market.” BASF promotion of its GMO products has been stalled in the last couple years. BASF fought for a decade before obtaining European Union (EU) marketing authorization in 2010 for Amflora, a genetically modified high-starch potato. Shortly afterwards BASF mistakenly planted in an Amflora field in Sweden another of its GMO potatoes, Amadea, which had not received authorization from European officials. According to the company, after this scandal, “European sentiment towards transgenic products declined further.” BASF plans to halt the planting and […]

(Beyond Pesticides, January 13, 2012) A U.S. District Judge in San Francisco has issued a ruling finding that the U.S. Department of Agriculture’s (USDA) decision to deregulate genetically engineered (GE) alfalfa was not unlawful, as has been charged by organic and environmental advocates, including Beyond Pesticides. Judge Samuel Conti of the U.S. District Court for the Northern District of California found that USDA did not act improperly by deregulating the GE Roundup Ready alfalfa, developed by Monsanto Co., and that the agency’s environmental review of the product was adequate. The plaintiffs in the case, including conventional farmers and seed growers, with Center for Food Safety serving as legal counsel, argued that the environmental impact statement (EIS) the agency prepared failed to take several critical matters into consideration in its evaluation. Among the issues neglected by the EIS are the impacts that the crop would have on endangered species, which advocates hold is required to be considered under the Endangered Species Act, as well as the potential effects that the likely increased pesticide applications would have on the environment. For these reasons, the groups argued that the EIS was woefully incomplete and that the agency’s subsequent deregulation of the GE alfalfa […]

(Beyond Pesticides, January 11, 2012) On January 10, beekeepers from across the country gathered at a national conference, with environmental organizations at their side, to draw attention to the growing plight facing their industry —the decline of honey bees, a problem that has far reaching implications for the U.S. economy. The disappearance of the bees alerts us to a fundamental and systemic flaw in our approach to the use of toxic chemicals -and highlights the question as to whether our risk assessment approach to regulation will destroy our food system, environment, and economy. “Bees and other pollinators are the underpinnings of a successful agricultural economy,” said Brett Adee, Co-Chair of the National Honey Bee Advisory Board and owner of Adee Honey Farms. “Without healthy, successful pollinators, billions of dollars are at stake.” Many family-owned beekeeping operations are migratory, with beekeepers traveling the country from state-to-state, during different months of the year to provide pollination services and harvest honey and wax. Bees in particular are responsible for pollinating many high-value crops, including pumpkins, cherries, cranberries, almonds, apples, watermelons, and blueberries. So any decline in bee populations, health and productivity can have especially large impacts on the agricultural economy (see factsheet). Honey […]

(Beyond Pesticides, January 10, 2012) A Purdue University study shows that honey bees’ exposure to the highly toxic neonicotinoid pesticide clothianidin, as well as thiamethoxam, is greater than previously thought. Beyond Pesticides, as a part of a coalition of beekeeping and environmental groups, challenged the Environmental Protection Agency (EPA) in a December 2010 letter for allowing the continued use of this bee-killing pesticide after EPA admitted in a leaked memo that its field study on bees is inadequate. The study, “Multiple Routes of Pesticide Exposure for Honey Bees Living Near Agricultural Fields,” was published January 3, 2012 in the online edition of PLoS ONE. Like other neonicotinoid pesticides, clothianidin is a systemic pesticide, which is taken up by a plant’s vascular system and expressed through pollen, nectar, and gutation droplets. It is most commonly applied by seed treatment. Most pesticides that are toxic to bees carry a warning that the product cannot be applied while foraging bees are present. As this study shows, systemic pesticides continue to expose and poison bees throughout foraging season. The study authors decided to take a closer look at clothianidin routes of exposure because of its prevalence in honey bee pollen and comb material, combined […]

(Beyond Pesticides, January 5, 2012) Just as everyone was getting ready for the holidays, the U.S. Department of Agriculture (USDA) approved yet another genetically modified seed by Monsanto, a drought-tolerant variety of corn, MON87460. In addition to its announcement approving Monsanto’s newest GE corn variety, USDA also opened a 60-day public comment period for two additional petitions — one for Monsanto’s GE soybean containing higher levels of an omega-3 fatty acid, that does not naturally occur in soybeans, and the other from Dow AgroSciences for corn that has been genetically engineered to resist the poisonous herbicide 2,4-D. “In 2012 the USDA is proposing approving a new GE corn variety that is resistant to a different toxic herbicide, escalating the toxic treadmill in chemical-dependent agriculture,” said Jay Feldman, Executive Director of Beyond Pesticides. “This is nothing more than a band-aid solution to a serious problem, and will only give rise to more superweeds, more herbicide pollution in our environment, more herbicide poisoning, while likely leading to the need for even more toxic herbicides a couple of years down the line. This foolish circle has to end,” he added. [To listen to a radio interview on 2,4-D by Jay Feldman click here.] […]

(Beyond Pesticides, December 5, 2011) On December 3, the 27th anniversary of the Bhopal pesticide plant disaster in Bhopal, India, a trial began in an international people’s court in India involving the world’s six largest pesticide companies: Monsanto, Syngenta, Bayer, BASF, Dow and Dupont. These companies, collectively known as the “Big 6,” are cited by prosecutors for their human rights violations, including internationally recognized rights to life, livelihood and health. Beyond Pesticides joined Pesticide Action Network (PAN) and others in signing a joint statement demanding that these companies be held accountable for their human rights violations, which was presented at the trial. The trial, hosted by PAN International, is facilitated by the Permanent People’s Tribunal (PTT), an international opinion tribunal independent from State authorities. The prosecution’s 230-page indictment outlines the global threats to human rights. It begins: The victims and survivors of [pesticide industry] aggression are the poor peasants, small-scale farmers, agricultural workers, rural women, children, and indigenous and agricultural communities around the world. They are at the mercy of the expanding power of the agrochemical [corporations] and are losing their control over their seeds and knowledge, and suffering debilitating physical and chronic effects due to pesticide poisoning, including coping […]

(Beyond Pesticides, November 30, 2011) A federal judge in southern Illinois has ordered the Swiss parent company of Syngenta Crop Protection Inc. (SCPI), maker of the herbicide atrazine, to appear in court to defend its actions in a water-contamination lawsuit brought last year by Midwestern public water providers. The suit was filed by the law firm Korein Tillery of St. Louis, MO and holds that Syngenta is responsible for the costs the water utilities incurred in order to clean municipal drinking water supplies of atrazine. The order marked the first time the Swiss company has ever been held subject to the jurisdiction of U.S. courts. The notably detailed opinion by District Judge J. Phil Gilbert of the U.S. District Court for the Southern District of Illinois was handed down the day before Thanksgiving and found that Syngenta AG (SAG) — the Basel, Switzerland-based international conglomerate — “has organized its group of subsidiary companies, including SCPI, purposefully to limit the jurisdictions in which it is subject to court authority.” Judge Gilbert focused on substance over form, however, and exercised jurisdiction because voluminous evidence revealed SAG’s pervasive operational control over SCPI — the agrochem giant based in Greensboro, N.C. that manufactures and […]

(Beyond Pesticides, November 23, 2011) A Federal Court of Canada has ordered Health Canada -the nation’s public health department- to take a second look at the impacts on amphibians of glyphosate-based pesticides, one of the most widely-used pesticides in Canada and the U.S., which includes products like Monsanto’s Roundup. The decision was the result of an action brought by a pesticide-activist and pediatrician, Josette Wier, M.D., and orders Health Canada to address requests by the public for a review of the safety of a pesticide where there is serious scientific concern about its risks. Dr. Wier’s legal challenge focused on wetlands that provide critical habitat for many species of frogs and amphibians. The original request for a special review of glyphosate-pesticides, especially those containing the “inert” ingredient polyoxyethyleneamine (POEA), and a subsequent 2009 legal challenge was brought because of her concern about possible aerial spraying of Monsanto’s pesticide in the forests near her community in Smithers. In her suit, Dr. Weir stated that the evidence “challenges the scientific validity of the previous evaluations” that led to the registration of the glyphosate herbicides containing POEA. Judge Michael Kelen of the Federal Court of Canada in his decision wrote, “[Dr. Wier] is […]

(Beyond Pesticides, November 15, 2011) Research published in the online edition of Environmental Health Perspectives finds that exposure to certain pesticides elevates the risk of non-Hodgkin’s Lymphoma (NHL). The study, “A Prospective Study of Organochlorines in Adipose Tissue and Risk of non-Hodgkin’s Lymphoma,” finds a positive correlation between levels of the organochlorine pesticides DDT, cis-nonachlor, chlordane, and their breakdown products in human fat tissue and the often deadly form of cancer. The researchers from the Danish Cancer Society’s Institute of Cancer Epidemiology conducted a case-cohort study using a prospective Danish cohort of 57,053 persons enrolled between 1993 and 1997. Within the cohort they identified 256 persons diagnosed with NHL in the population-based nationwide Danish Cancer Registry and randomly selected 256 sub-cohort persons. The research team measured concentrations of eight pesticides and ten polychlorinated biphenyl congeners (PCBs) in fat tissue collected upon enrollment. The results indicate a higher risk of NHL in association with higher fat tissue levels of DDT, cis-nonachlor and oxychlordane, but shows no association with PCBs. Because the tissue samples were taken up to 15 years prior to the cancer diagnosis, the research suggests that exposure to these organochlorines increases the risk of NHL later in life and […]

(Beyond Pesticides, November 8, 2011) The Environmental Protection Agency (EPA) published a petition to ban the endocrine (hormone) disrupting herbicide atrazine on September 14, 2011, opening a 60-day comment period for the public to weigh-in on the issue that ends Friday. Tell EPA that because atrazine poses unacceptable risks to humans and wildlife, the agency should remove this hazardous pesticide from the market immediately. Submit comments directly to EPA’s atrazine petition docket by November 14, 2011 or sign your organization or business onto Beyond Pesticides’ comments by Friday, November 11. According to its Federal Register notice, EPA received a petition from the non-profit organization Save the Frogs that includes over 10,000 signatures and select statements from the public, as well as two brief summaries of published literature, one by Jason Rohr, PhD (University of South Florida), and one by Tyrone Hayes, PhD (University of California, Berkeley), that is co-authored by 39 other scientists. In conjunction with the petition, EPA received nearly 50,000 emails from supporters of the Center for Biological Diversity and the Natural Resources Defense Council requesting that EPA “immediately take steps to phase out atrazine use in the United States,” stating that atrazine poses an unreasonable risk to […]

(Beyond Pesticides, November 7) Once heralded as a breakthrough for reducing the rates and toxicity of the pesticides applied by farmers, genetically engineered (GE) crops are perversely leading to renewed dependency on the very herbicides they were claimed to make obsolete. Growing recognition that pervasive planting of “Round-Up Ready” corn, soybeans and cotton is accelerating weed resistance is prompting GE seed companies to rush to market ‘stacked’ varieties that are resistant to additional herbicides, including 2, 4-D and dicamba. Farmers planting the stacked varieties will be spraying these older herbicides in addition to glyphosate, which most commodity crops have already been engineered to tolerate. Professor David A. Mortensen of Pennsylvania State University has estimated that adoption of Round-Up Ready and 2, 4-D or dicamba resistant stacked varieties in soybeans could result in a 70% increase in herbicide use in a relatively short time. The St. Louis Pots-Dispatch reported on progress that multinational chemical corporations Dow AgroSciences, BASF, and Monsanto are making to bring multi-herbicide resistant varieties to market. Under separate arrangements with each company, Monsanto adds glyphosate resistance to seeds that are simultaneously engineered to resist other herbicides. In October, Dow AgroSciences obtained a global patent on its Enlist Duo […]

(Beyond Pesticides, November 2, 2011) On Monday, a federal judge rejected a lawsuit brought by Dow AgroSciences challenging pesticide application restrictions to protect salmon and upheld the measures recommended by the National Marine Fisheries Service (NMFS) to protect endangered salmon and steelhead from three highly toxic pesticides: chlorpyrifos, diazinon, and malathion. The restrictions, recommended by NMFS’s Biological Opinion in 2008, ban the ground spraying of the three commonly used organophosphate agricultural insecticides within 500 feet of any salmon-bearing waterway, and aerial spraying within 1,000 feet. NMFS has issued four Biological Opinions, the latest on June 2011, which call for several limitations on aerial spraying and ground application of the pesticides near salmon waters, as well as buffer zones around salmon waters and ditches that drain to salmon habitat, among others. EPA was court ordered to consult with NMFS to identify measures needed to protect salmon and steelhead from the pesticides as a result of a 2002 and 2007 lawsuit. Pesticide manufacturers have been willfully ignoring and challenging NMFS’s findings. Dow AgroSciences alleged that NMFS used bad data and modeling and that the proposed buffers are far too large. Earthjustice, representing Northwest Center for Alternatives to Pesticides (NCAP), Pacific Coast Federation […]

(Beyond Pesticides, October 28, 2011) St. Louis-based chemical and seed giant Monsanto Co. has purchased a company called Beeologics, which has developed a product intended to counteract viral agents that plague honey bee colonies in an attempt to stem the effects of Colony Collapse Disorder (CCD). However, advocates wonder whether the antiviral agent will result in any significant decline of CCD when bees around the country and across the world continue to be exposed to highly toxic pesticides that are known to have serious effects on a range of pollinators, including honey bees. Beeologics was founded in 2007 and is headquartered in both Florida and Israel. The company’s antiviral agent, called Remembee, is designed to fight a virus that is commonly thought to be a contributing factor to CCD. According to the St. Louis Post-Dispatch, Monsanto spokesperson Kelly Powers said that, “I don’t need to tell you how important bees are to farmers who rely on pollination, and Remembee has great promise, pending approvals.” The product is currently being reviewed for potential commercial sale by the U.S. Food and Drug Administration. Efforts to counteract CCD are commendable, as a range of factors, including viruses as well as colony invaders such […]
