(Beyond Pesticides, February 1, 20011) On January 31, 2011, a coalition of organic companies and environmental organizations, including Beyond Pesticides, released an open letter and call to action on the U.S. Department of Agriculture’s (USDA) January 27 decision to deregulate “RoundUp Ready” (glyphosa te-tolerant) genetically engineered (GE) alfalfa, allowing its unrestricted cultivation and threatening organic and non-GE conventional farmers. It sets a precedent for future deregulation of GE crops. The letter encourages individuals to write to President Obama opposing the decision and asking that the administration reconsider its position. Other signatories include upcoming National Pesticide Forum keynote Maria Rodale (CEO, Rodale, Inc. and author of Organic Manifesto), National Organic Coalition, Center for Food Safety, Organic Trade Association, Organic Valley, Stonyfield Farm, and more. The decision to deregulate GE alfalfa follows USDA’s completion of the court-mandated environmental impact statement (EIS). Secretary of Agriculture Tom Vilsack called for “coexistence” among GE, organic and conventional non-GE farmers, despite the clear recognition in the EIS that GE contamination of organic and conventionally grown crops presents a huge problem. The EIS also fails to take into account the documented increase in herbicide-resistant “super weeds” that is requiring the use of highly toxic herbicide cocktails for […]

(Beyond Pesticides, January 28, 2011) Environmental and public interest groups are extremely disappointed with the announcement late Thursday that the U.S. Department of Agriculture (USDA) plans to fully deregulate genetically engineered (GE) alfalfa seed, despite the risks it poses to both organic and conventional farmers. Among those upset with the announcement are the cosponsors of the original Organic Foods Productions Act, Senator Patrick Leahy (D-Vt.) and Representative Peter DeFazio (D-OR), who have weighed in with their criticism of USDA’s decision. This decision follows the agency’s completion of the court-mandated environmental impact statement (EIS) for GE alfalfa. Secretary of Agriculture Tom Vilsack called for “coexistence” among GE, organic and conventional non-GE farmers, despite the clear recognition in the EIS that GE contamination of organic and conventionally grown crops presents a huge problem. The EIS also fails to take into account the documented increase in herbicide-resistant “super weeds” that is requiring the use of highly toxic herbicide cocktails for weed control on conventional farms. Likewise, USDA has not shown that contamination-free coexistence with deregulated GE alfalfa is likely or possible. “We’re disappointed with USDA’s decision and we will be back in court representing the interest of farmers, preservation of the environment, and […]

(Beyond Pesticides, January 25, 2011) Research by the U.S. Department of Agriculture’s (USDA) Bee Research Laboratory and Penn State University shows that the neonicotinoid insecticide imidacloprid contribute —at extremely low levels— to bee deaths and possibly colony collapse disorder (CCD), the widespread disappearance of honey bees that has killed off more than a third of commercial honey bees in the U.S. While the study has not been published yet, the UK’s The Independent newspaper reports that honeybees exposed to imidacloprid are more susceptible to the fungal pathogen Nosema. This is the first study to show that neonicotinoids impact the survival of bees at levels below the level of detection, meaning that field studies would not have considered the role of the pesticide, because they would not have detected it. USDA researcher Jeffrey Pettis, PhD and Penn State University researcher Dennis Van Engelsdorp, PhD explained their research in the 2010 documentary, The Strange Disappearance of the Honeybees (transcript courtesy of Grist.org): [Pettis] I’ve done a recent study actually in collaboration with Dennis van Engelsdorp and some other researchers, where we exposed whole colonies to very low levels of neo-nicotinoids in this case, and then ”˜challenged’ bees from those colonies, with Nosema […]

(Beyond Pesticides, January 21, 2011) Further proof of the ineffectiveness of chemical pest control has emerged in the form of a study from The Ohio State University documenting the growing resistance of bed bugs to pesticide treatments. The study shows that modern bed bugs have developed the ability to defend themselves against pyrethroid pesticides, due in part to the widespread use of such treatment methods. These findings highlight the need for widespread adoption of alternative, non-chemical methods for controlling bed bugs and other insect pests. The study, which was published in the journal PLoS ONE, is entitled “Transcriptomics of the Bed Bug (Cimex lectularius).” The researchers found that the bugs developed the ability to produce certain enzymes, which can break down toxic chemicals, at higher levels of than previous generations. These enzymes allow the chemicals to be easily excreted by the insects without being harmed. When comparing modern bugs to a colony that has existed in isolation for several decades — without any exposure to pesticides — the team found strong evidence of resistance. Bugs from the isolated colony were readily killed when exposed to even small amounts of pyrethroids. However, the modern bugs, which have been exposed to pesticide […]

(Beyond Pesticides, January 7, 2011) The Office of the Inspector General (OIG) for the U.S. Environmental Protection Agency (EPA) has released a report criticizing the agency’s lack of regulation concerning antimicrobial products. Citing a number of failures, the report finds that the EPA’s Antimicrobial Testing Program (ATP) has been largely inadequate in testing products to ensure safety and efficacy, and has failed to remove products that did not meet program standards. This report is especially of concern because some antimicrobials, such as triclosan, are known to cause dangerous public health and environmental hazards. Triclosan is one of the most prevalent antibacterial compounds found in products ranging from soaps and toothpastes to fabrics and toys. Studies have increasingly linked triclosan (and its chemical cousin triclocarban), to a range of adverse health and environmental effects, from skin irritation, allergy susceptibility, bacterial, endocrine disruption and compounded antibiotic resistant, tainted water, and dioxin contamination to destruction of fragile aquatic ecosystems. Through ATP, antimicrobial products including hospital disinfectants and tuberculocides are meant to be tested to ensure that they meet health standards and that the claims on the product labels are accurate. However, OIG has found that “EPA’s implementation of the ATP has not delivered […]

(Beyond Pesticides, January 3, 2011) The United Nations Food and Agriculture Organization (FAO) has announced the initial results of an experimental program in West Africa that reduces farmers’ use of pesticides and chemical inputs while increasing yields and income. The program, entitled the West African Regional Integrated Production and Pest Management Program, evaluated the use of ecological management versus conventional practices on vegetables, cotton, and grain crops in the countries of Benin, Burkina Faso, Mali, and Senegal. The evaluation shows dramatic decreases in pesticide usage, reduced environmental degradation, as well as increases in farmer income through higher yields and reduced inputs. According to the FAO (which previously advocated for organic agriculture), the goals of the program, which is ongoing, are “building local farming capacity, improving food security and livelihoods, and raising awareness of negative externalities and positive alternatives.” These are accomplished through training farmers in what the FAO calls integrated production and pest management (IPPM) methods so that they can reduce toxic inputs and pollution while enhancing soil fertility and retaining more of their income. The particular methods of IPPM include reducing pesticide usage, soil building through incorporation of compost and manure and the planting of cover crops, careful monitoring […]

(Beyond Pesticides, December 14, 2010) A petition of more than a million signatures was presented to the European Commission last week, demanding a halt to approvals of new genetically modified (GM) crops and the establishment of up a new scientific body to study the impact of the technology and determine regulations. Greenpeace led the effort. The petition is seen as a test case for the “European citizen’s initiative,” introduced under the European Union’s new constitutional treaty, which enables a million or more people to jointly ask the European Commission to change EU legislation. It follows the Commission’s decision in March to grant the first EU GM cultivation approval in 12 years for the “Amflora” potato. “Over a million people across Europe have set the EU a democratic test — will the EU address the real concern people have about GM crops and food, or will it side with the chemical industry lobbyists controlling GM technology?” Greenpeace’s EU Director Jorgo Riss said. “Until safety issues of GMs are examined by independent experts, all GM authorizations should stop.” A spokesman for the EU executive said it would treat the signatures “as a petition in the spirit of the citizen’s initiative,” Despite the […]

(Beyond Pesticides, December 9, 2010) Beekeepers and environmentalists called on the U.S. Environmental Protection Agency (EPA) December 8, to remove a pesticide linked to Colony Collapse Disorder (CCD), citing a leaked EPA memo that discloses a critically flawed scientific support study. The November 2nd memo identifies a core study underpinning the registration of the insecticide clothianidin as unsound after EPA quietly re-evaluated the pesticide just as it was getting ready to allow a further expansion of its use. Clothianidin (product name “Poncho”) has been widely used as a seed treatment on many of the country’s major crops for eight growing seasons under a “conditional registration” granted while EPA waited for Bayer Crop Science, the pesticide’s maker, to conduct a field study assessing the insecticide’s threat to bee colony health. Bayer’s field study was the contingency on which clothianidin’s conditional registration was granted in 2003. As such, the groups are calling for an immediate stop-use order on the pesticide while the science is redone, and redesigned in partnership with practicing beekeepers. They claim that the initial field study guidelines, which the Bayer study failed to satisfy, were insufficiently rigorous to test whether or not clothianidin contributes to CCD in a real-world […]

(Beyond Pesticides, November 22, 2010) The British Beekeepers’ Association (BBKA) last week announced plans to end its controversial practice of endorsing pesticides for financial benefit from leading chemical manufacturers. The endorsement of four products as “bee-friendly” caused outrage among many beekeepers because one of the companies, Bayer Crop Science, makes pesticides like imidacloprid, an insecticide widely implicated in the deaths of honeybees worldwide. The 135-year-old charity endorsed pesticides used to combat the varroa mite that is linked to the collapse of colonies as “bee-friendly.” In return, for the past 12 years the association has received ÂŁ17,500 ($27,949) a year from Bayer Crop Sciences and Syngenta. This relationship angered many members and some left the association. However, the BBKA denies that it has bowed to pressure from members who have been increasingly critical of its relationship with Bayer and other chemical companies. In a statement sent out this week to the secretaries of local beekeeping associations across the UK, the BBKA’s president, Martin Smith, said: “Following discussion with the companies involved, the BBKA trustees have decided that endorsement and related product-specific payments will cease as soon as practically possible.” He added: “The four products subject to BBKA endorsement are of declining […]

(Beyond Pesticides, October 8, 2010) Scientists may have found the missing link behind the colony collapse disorder (CCD): a combination of a virus and a fungus, though more research is needed to determine the exact cause and effect that these two culprits have on CCD. Prior to this study, scientists have hypothesized that there are numerous factors, including pesticides, that depress the immune and nervous system of bees, creating a vulnerability to other factors, such as those identified in this study. Army scientists in Maryland and entomologists in Montana teamed up to find that the co-occcurrence of the viruses, the invertebrate iridescent virus (IIV) with the fungus Nosema ceranae (which was previously implicated as a culprit) consistently marked a colony collapse. The study, Iridovirus and Microsporidian Linked to Honey Bee Colony Decline was published October 6th in the online science journal PLoS One. Researchers looked at the proteins of thousands of healthy and collapsing bee colonies using mass spectrometry-based proteomics (MSP) that revealed two previously unreported RNA viruses in honey bees in North America, one of which is the IIV. Researchers say this virus is similar to a virus that was first reported in India 20 years ago, as well […]

(Beyond Pesticides, October 6, 2010) Organic and genetically modified organism (GMO)-free conventional farmers and food processors need legal certainty that they can continue to produce food free of GMO contamination. This, according to the International Federation of Organic Agriculture Movements (IFOAM)— EU Regional Group, which responded to a presentation by EU Commissioner for Health and Consumer Protection John Dalli on “best practice document” for genetically modified (GM) maize. The best practice document outlines voluntary guidelines for the coexistence of genetically modified crops with conventional and organic farming, but fails to address the economic and social impacts on contaminated non-GMO farms. Commissioner Dalli presented to the Farm Council proposals on GMO cultivation, as well as a new “best practice document” for maize. “Commissioner Dalli is trying to snake his way through crucial GMO policies by attempting to satisfy all conflicting parties with his proposals to the Farm Council this morning. But his approach still fails to solve the main problems,” comments Christopher Stopes, President of the IFOAM EU Group. “Consumers refuse to eat GMOs which is their democratic right.” The best practice document authored by the European Coexistence Bureau, developed in light of a July 2010 recommendation, reflects the possibility for […]

(Beyond Pesticides, October 1, 2010) A new study by University of Notre Dame ecologist Jennifer Tank, PhD and colleagues reveals that streams throughout the Midwest are contaminated with transgenic materials from corn crop byproducts, even six months after harvest. The transgenic corn has been genetically engineered (GE) to produce its own insecticide, a toxin from the soil bacterium Bacillus thuringiensis (Bt). In a 2007 paper in the Proceedings of the National Academy of Science (PNAS), Dr. Tank and a group of researchers demonstrated that transgenic materials from corn (pollen, leaves, cobs) do, in fact, enter streams and can be subsequently transported to downstream water bodies. In a paper, “Occurrence of maize detritus and a transgenic insecticidal protein (Cry1Ab) within the stream network of an agricultural landscape,” published in the September 27, 2010 edition of PNAS, the researchers write about their nvestigation of the fate and persistence of the material and its associated Cry1Ab insecticidal protein, using a synoptic field survey of 217 stream sites in northwestern Indiana six months after crop harvest. “We found that corn crop byproducts were common in agricultural streams and that 86 percent of sites contained corn leaves, cobs, husks and/or stalks in the active stream […]

(Beyond Pesticides, September 30, 2010) A new study finds a clear link between a decline in wild pollinators and reduced vegetable yields in India, which researchers say will harm both the nation’s GDP as well as access to a nutritional diet. Parthiba Basu, PhD, one of the researchers from the University of Calcutta’s Ecology Research Unit, says that nutritional security in India will be affected as a result of the decline, since the vegetables that rely on pollination substantially provide essential nutrients to the population. The research team, which presented its findings at a recent British Society meeting at the University of Leeds, compared the yields of pollinator-dependent crops such as pumpkins, squash and cucumbers with pollinator-independent crops, such as cereals. The data shows that while yields of pollinator-independent crops continue to increase, the crops that are dependent on pollinators have leveled off. Though the researchers would have liked to specifically compare pollinator abundance over the years, this kind of data is not currently available in India. The use of domesticated bees for pollinating crops is not widespread in India and across South Asia, according to Dr. Basu. He attributes the “political noise” in the U.S. and Europe on the […]

(Beyond Pesticides, August 3, 2010) A new study shows that due to a flaw in standard risk assessments, which consider toxic effects at fixed exposure times, the risks posed by the neonicotinoid pesticides imidacloprid and thiacloprid are likely to be underestimated. The authors believe that minute quantities of imidicloprid may be playing a much larger role in killing bees over extended periods of time than previously thought. The study, “The significance of the Druckrey—KĂĽpfmĂĽller equation for risk assessment””The toxicity of neonicotinoid insecticides to arthropods is reinforced by exposure time,” was published online July 23, 2010 in the journal Toxicology. The authors believe that standard risk assessment calculations underestimate toxicity because they do not accurately account for the interplay of time and level of exposure. According the study: The essence of the Druckrey—KĂĽpfmĂĽller equation states that the total dose required to produce the same effect decreases with decreasing exposure levels, even though the exposure times required to produce the same effect increase with decreasing exposure levels. Druckrey and KĂĽpfmĂĽller inferred that if both receptor binding and the effect are irreversible, exposure time would reinforce the effect. The Druckrey—KĂĽpfmĂĽller equation explains why toxicity may occur after prolonged exposure to very low toxicant […]

(Beyond Pesticides, July 22, 2010) In a press release submitted last week, the Monsanto Company, Inc. announced that it has taken a vital step towards commercializing a new soybean product that is tolerant to the neurotoxic pesticide dicamba by completing its regulatory submission to the U.S. Department of Agriculture (USDA) for dicamba-tolerant soybeans. Monsanto expects to complete regulatory submission to the USDA and key global markets in the coming months. The dicamba tolerance trait is expected to also be stacked with the glyphosate-resistant, or “Roundup Ready” soybean trait upon commercialization. While Monsanto claims that this is a “highly effective and economical weed control package,” it is likely to be similar to Roundup (glyphosate) Ready crops, just another way to sell more pesticide product. Monsanto is banking on the idea that mixing dicamba with glyphosate will help manage the hard-to-control broadleaf weeds in chemical-intensive farming systems, targeting both pre-plant and post-emergence weed control in an effort to reduce resistance. In a report published last year, analysts found that genetically engineered (GE) crops have been responsible for an increase of 383 million pounds of herbicide use in the U.S. over the first 13 years of commercial use of GE crops (1996-2008). The […]

(Beyond Pesticides, July 14, 2010) The U.S. Environmental Protection Agency (EPA) announced that Monsanto Company Inc. has agreed to pay a $2.5 million penalty to resolve misbranding violations related to the sale and distribution of cotton seed products containing genetically engineered (GE) pesticides. This is the largest civil administrative penalty settlement ever received under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). “This agreement shows that when a company violates the law by distributing misbranded pesticides, EPA will take action,” said Cynthia Giles, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance. “The regulated community should understand that we take these violations seriously, and the public will accept nothing less than compliance.” “People who manufacture and distribute pesticide products must follow the federal registration requirements,” said Steve Owens, assistant administrator for EPA’s Office of Chemical Safety and Pollution Prevention. “These requirements are critical to preventing the development and spread of insect resistance.” Monsanto Bollgard and Bollgard II cotton seed products contain genetically engineered pesticides known as plant incorporated protectants (PIPs), which are registered as a pesticidal product under FIFRA. As a condition of the registrations, EPA included planting restrictions on Bollgard and Bollgard II, which contain the PIP Bacillus […]

(Beyond Pesticides, March 30, 2010) Searching for clues to the mysterious disappearance of bees, known as “colony collapse disorder”(CCD), Penn State University researchers have identified widespread pesticide contamination of beehives. The study, “High Levels of Miticides and Agrochemicals in North American Apiaries: Implications for Honey Bee Health,” was published March 19, 2010 in the scientific journal Public Library of Science (PLOS). The study finds 121 different types of pesticides within 887 wax, pollen, bee and hive samples from 23 states. The top 10 most frequently detected pesticides are fluvalinate, coumaphos, chlorpyrifos, chlorothalonil, amitraz, pendamethalin, endosulfan, fenpropathrin, esfenvalerate and atrazine. Miticides are the most common contaminant in the wax and bees, and fungicides are the most common contaminant of pollen. For the full results of the study, including several tables of wax, pollen and bee sample data, download the study from the PLOS website. “The pollen is not in good shape,” Chris Mullin, PhD, lead author of the study, told Discovery News. The authors state that the 98 pesticides and metabolites detected in mixtures up to 214 parts per million (ppm) in bee pollen alone represents a remarkably high level for toxicants in the brood and adult food of this primary […]

(Beyond Pesticides, March 10, 2010) A study investigating the sublethal effects of pyrethroids, bifenthrin and deltamethrin on honeybees finds that the chemicals significantly impair the pollinators’ reproduction. The researchers also point out that the concentration of each pesticide that produced adverse effects in the experiments was at or below those that bees could encounter while pollinating treated crop fields. “Effects of sublethal concentrations of bifenthrin and deltamethrin on fecundity, growth, and development of the honeybee Apis mellifera ligustica” published in the March issue of Environmental Toxicology & Chemistry, investigated the effects of the two pesticides at sublethal concentrations on fecundity, growth, and development of honeybees were examined with the feeding method for a three-year period (2006-2008). It was shown that both bifenthrin and deltamethrin significantly reduced bee fecundity, decreased the rate at which bees develop to adulthood, and increased their immature periods. Queens in the control group in 2006 laid a little more than 1,200 eggs each day, compared to not quite 900 a day in the bifenthrin group and roughly 600 per day in the deltamethrin group. In general, the hatch rate of pyrethroid-exposed eggs was also significantly depressed. The success rate of hatchlings, that is the share that […]

(Beyond Pesticides, February 3, 2010) Beyond Pesticides has confirmed exciting additions to Greening the Community, the 28th National Pesticide Forum, scheduled for April 9-10 at Case Western Reserve University in Cleveland, OH. The Forum is an important opportunity to discuss the latest information on pesticides and alternatives, meet scientists and community leaders, and network with other activists working to change policies at the local, state and national levels. David Hackenberg, the beekeeper who first discovered a mysterious disappearance of honeybees now known as colony collapse disorder (CCD), is the most recent addition to the program. Mr. Hackenberg believes that pesticides contribute to CCD and that honeybees are a barometer of the environment. Featured in several films and news investigations, he has been front and center in this important fight to protect our pollinators. Read about Mr. Hackenberg and the other Forum speakers in the highlights below. The Forum will begin Friday afternoon with a tour of the Cleveland Botanical Garden. Founded in 1930, Cleveland Botanical Garden, which is now made up of 20 specialty gardens and exotic indoor biomes, has evolved into a community treasure. The Garden’s community involvement extends beyond its 10 acres into city neighborhoods through its Green […]

(Beyond Pesticides, January 4, 2010) — A pesticide that could be dangerously toxic to America’s honey bees must be pulled from store shelves as a result of a suit filed by the Natural Resources Defense Council (NRDC) and the Xerces Society. In an order issued in December, a federal court in New York invalidated EPA’s approval of the pesticide spirotetramat (manufactured by Bayer CropScience under the trade names Movento and Ultor) and ordered the agency to reevaluate the chemical in compliance with the law. The court’s order goes into effect on January 15, 2010, and makes future sales of Movento illegal in the United States. “This sends EPA and Bayer back to the drawing board to reconsider the potential harm to bees caused by this new pesticide,” said NRDC Senior Attorney Aaron Colangelo. “EPA admitted to approving the pesticide illegally, but argued that its violations of the law should have no consequences. The Court disagreed and ordered the pesticide to be taken off the market until it has been properly evaluated. Bayer should not be permitted to run what amounts to an uncontrolled experiment on bees across the country without full consideration of the consequences.” In June 2008, EPA approved […]

(Beyond Pesticides, November 3, 2009) Research by scientists at the University of Florida (UF) links Colony Collapse Disorder (CCD), the widespread disappearance of honey bees that has killed off more than a third of commercial honey bees in the U.S., to larval exposure to a cocktail of frequently used pesticides. Led by UF Institute of Food and Agricultural Sciences bee specialist Jamie Ellis, PhD, the researchers have finished a first round of testing on bee larvae exposed to the pesticides most commonly found in bee hives. The results were presented on October 22 at a meeting of the North American Pollinator Protection Campaign (NAPPC), which funded the study. The work gives insight into how the larvae react to these pesticides, which are usually only tested on adult bees, and sets the stage for the researchers to test the bees’ reaction to combinations of these pesticides. Just like mixing the wrong medications can have deadly and unpredictable results in humans, chemical mixtures pose a quandary for the bee industry. Bees are commonly exposed to multiple pesticides that are either applied to or nearby their hives. “Beeswax, honey and pollen can contain low mixtures of fungicides, insecticides, and herbicides. The larvae develop […]

(Beyond Pesticides, September 8, 2009) Researchers at the University of Nebraska-Lincoln believe they may have determined the first causal relationship linking colony collapse disorder (CCD) to pathogens and other environmental stresses, including pesticides. CCD is a disappearance of honey bees that has beset beekeepers killing off more than a third of commercial honey bees in the U.S. in 2006-2007. Their study, “Changes in transcript abundance relating to colony collapse disorder in honey bees,” was published September 1, 2009 in the Proceedings of the National Academy of Sciences. The team also included researchers from the University of Illinois and the U.S. Department of Agriculture. In a nutshell, the researchers determined, by comparing the differences in gene expression in healthy and CCD colonies, the infected colonies had considerably more damage in their ribosomes. (Ribosomes function in the expression of the genetic code from nucleic acid into protein in all animal, plant and fungal cells.) The infected hives also had higher rates of picorna-like viruses, which damage the ribosome. The researchers believe the loss of ribosomal function leaves the bees susceptible to pesticides and other infections. The honey bee genome project was launched in 2006 by University of Illinois researchers. The new study […]
