(Beyond Pesticides, December 13, 2011) Despite opposition from Lake Tahoe water providers and environmental groups, the Lahontan Regional Water Quality Control Board (LRWQCB) voted last week to allow the use of pesticides to control invasive species like Asian clams and the underwater plants Eurasian watermilfoil and curly leaf pondweed. For years, the rules regulating pesticide use in Lake Tahoe limited their use to below detectable levels, creating a âde facto prohibition,â explains Mary Fiore-Wagner, an environmental scientist with the LRWQCB. The decision to allow the use of pesticides in the lake now rests in the hands of California State Water Resources Control Board. Carl Young, interim executive director of the League to Save Lake Tahoe/Keep Tahoe Blue, told the Associated Press that the plan poses a threat to the lake’s water quality and the public’s health, and he’s concerned visitors and residents could be exposed to pesticides through Tahoe’s fish and drinking water. The League is urging regulators to use non-chemical methods, including bottom barriers that involve the use of large mats to starve the species of sunlight and oxygen. The aquatic plants can be managed through mechanical harvesting. The U.S. Army Corps of Engineers estimates economic impacts from introductions […]

(Beyond Pesticides, December 12, 2011) Continuing a long tradition of public participation in setting organic standards, more than one thousand people submitted comments leading up to the National Organic Standards Board (NOSB) meeting in Savannah, GA between November 30 and December 1. View webcast of 4-day meeting. The comments were in response to specific agenda items which the NOSB was convening to consider, including many important materials review decisions. At the meeting, NOSB members frequently cited both individual comments and the collective weight of public opinion as decisive factors in determining how they voted. Beyond Pesticides thanks everyone who used our Keeping Organic Strong webpage as a resource for developing their comments and encourages the public to continue making your voice heard in the development of organic standards. The NOSB was established under the Organic Foods Production Act of 1990 (OFPA) which authorizes the U.S. Department of Agriculture (USDA) to operate an organic certification program. Appointed by the Secretary of Agriculture, the 15-member NOSB is responsible for making recommendations on whether a substance should be allowed or prohibited in organic production or handling, assisting in the development of standards for substances used in organic production, and advising the Secretary on […]

(Beyond Pesticides, December 1, 2011) Ongoing research at the U.S. Department of Agricultureâs (USDA) Sustainable Agricultural Systems Lab (SASL) finds that organic grain production reduces greenhouse gas emissions relative to chemical-intensive no-till and chisel-plow production systems. In fact, the research concludes that the organic system removes more greenhouse gases from the atmosphere than it contributes, while the other systems result in net increases. The results are based on data from comparable three-year crop rotations maintained for each production system at the Labâs farm in Beltsville, MD under the direction of Michel Cavigelli, PhD. The rotations mirror typical commercial grain production operations in the mid-Atlantic region that begin with corn followed by a rye grass cover crop, rotate to soybeans and winter wheat in the second year, and conclude with a legume crop. Dr. Cavigelliâs team identified the substantial energy savings achieved in the organic system by using natural fertility sources, especially for nitrogen, as the critical factor in reducing its overall impact on climate change. Previous research shows that carbon dioxide and nitrous oxide are the two most potent greenhouse gases that are produced and released as a consequence of crop production. It is also known that, due to its […]

(Beyond Pesticides, November 21, 2011) Two recent reports from the Organic Center can help consumers identify food choices that will reduce their intake of pesticides while enhancing the overall nutritional content of their diets. The reports, entitled Dietary Risk Index and Transforming Jane Doeâs Diet are based upon state-of-the-art pesticide residue and risk assessment research conducted by USDA and EPA. The reports establish that switching to organically produced and handled foods significantly reduces the amount of pesticides consumers will receive from their diet and that a few simple changes in behavior can drive such exposure to nearly zero. Noting that extensive research has identified fresh fruits and vegetables as by far the greatest source of pesticide exposure and risk in our diets, the Dietary Risk Index (DRI) report focuses on the relative risk of choices within these food groups. The DRI calculates expected risk by weighing the toxicity of a specific pesticide with the amount of the substance to which consumers are likely to be exposed. This estimated risk is then measured against the EPA-established âlevel of concernâ, the exposure level beyond which EPA can no longer assert a âreasonable certainty of no harm.â The DRI calculations for individual pesticides […]

(Beyond Pesticides, November 18, 2011) Organic crop systems can provide similar yields and much higher economic returns than a conventional corn-soybean rotation, according to thirteen years of data from a side-by-side comparison at Iowa State Universityâs Neely-Kinyon Research and Demonstration Farm. The Universityâs Long-Term Agroecological Research Experiment (LTAR) began in 1998 with support from the Leopold Center for Sustainable Agriculture. LTAR is one of the longest running replicated comparisons in the country. Kathleen Delate, PhD., professor in ISU Agronomy and Horticulture, leads the project. âThe transitioning years are the hardest years,â Dr. Delate said, explaining that the project was originally designed to help farmers make the shift into an organic system. To sell a product as organic, the crop must be raised for three years prior to harvest in accordance with organic systems plans on land that has not been treated with synthetic fertilizers and has only been exposed to substances placed on the “NationL List, ” which is established by the Organic Foods Production Act. The LTAR experiment shows that organic crops can remain competitive with conventional crops even during the three-year transition. Averaged over 13 years, yields of organic corn, soybean, and oats have been equivalent to or […]

(Beyond Pesticides, November 10, 2011) Two new studies released last week add further proof that the popularity of organic food is not just an elitist trend. One report by the Organic Trade Association (OTA), The 2011 U.S. Familiesâ Organic Attitudes and Beliefs Study, finds that 78 percent of U.S. families purchase organic food. Another study by SCALE, Inc. finds that organic food is generally cheaper at farmers markets than at grocery stores in Southeast U.S. OTA partnered with KIWI Magazine, and polled nearly 1,300 U.S. families about their attitudes and behaviors relating to organic food. The total sample reflects the target population of U.S. households with a confidence interval of +/-3% at the 95% confidence level. This is the third year the study has been conducted. According to OTA, it contains in-depth information about organic consumersâ demographics, purchase motivation, understanding of organic, willingness to substitute when organic is not available, and attitudes about genetically modified organisms (GMOs). The other study, Is Local Food Affordable for Ordinary Folks?, compares farmers markets and supermarkets throughout 19 different communities in six Southeast states, including Virginia, Tennessee, West Virginia, Kentucky, North Carolina and South Carolina. Though the study focuses on local foods, it did […]

(Beyond Pesticides, November 9, 2011) A 2009 European Union (EU) report on pesticide residues, published yesterday by the European Food Safety Authority (EFSA), shows food on the European market is still heavily contaminated with cocktails of pesticides. The percentage of EU food in shops and markets with multiple residues remains at a high level of 25.1%, meaning only a slight improvement in the last five years of reporting. The highest reported number of pesticide chemical residues in one food item remains at 26: One sample analyzed had 26 different pesticides! Like the U.S. where consumers are exposed through food and drinking water to a variety of chemical mixtures of pesticide food residues, EU citizens also continue to be exposed to mixtures of pesticides on a daily basis. According to the report , compliance with the legal maximum residue levels (MRLs) for pesticides in food rose to 97.4 percent of the analyzed samples in 2009, up by about one percentage point from 2008, EFSA said. However, like their counterparts in the U.S., the regulatory entities EFSA and European Commission still do not protect people against the effects of mixtures. Health standards for pesticide residues do not take these effects into account. […]

(Beyond Pesticides, November 4, 2011) On Tuesday, November 1, Senator Sherrod Brown of Ohio and Representative Chellie Pingree of Maine along with 35 original co-sponsors, introduced the Local Farms, Food, and Jobs Act (LFFJA) â S. 1773 and H.R. 3286 â a comprehensive bill intended for inclusion in the 2012 Farm Bill. The legislation helps farmers and ranchers by addressing production, aggregation, processing, marketing, and distribution needs to access growing local and regional food markets. The bill would provide critical support for a number of programs that benefit organic farmers and the organic industry, as well. It also assists consumers by improving access to healthy food. The measure provides secure farm bill funding for critically important programs that support organic and family farms, expand new farming opportunities, create rural jobs, and invest in the local food and agriculture economy. Take action. Among the provisions of the bill that would benefit organic producers are an increase in funding and payment caps for certification assistance, elimination of surcharges on crop insurance for organic farmers and development of more accurate price estimates, and expansion of specialty crop block grants that often are awarded to organic operations (âspecialty cropsâ being the U.S. Department of […]

(Beyond Pesticides, November 3, 2011) The State of Ohio announced Friday, October 28 it will rescind a regulation that has prohibited organic dairy product labeling from declaring that antibiotics, pesticides or synthetic hormones are not used. In a lawsuit filed by the Organic Trade Association (OTA), the Sixth Circuit Court of Appeals found that proposed restrictions violate the First Amendment of the constitution. As a result, Ohio has abandoned the rule, thus allowing labeling to proudly state that organic dairy products are produced in accordance with federal organic standards under the Organic Foods Production Act, and therefore without the use of synthetic growth hormones or antibiotics. âThis is significant for all of us who support what the organic foods are about, and for consumers who carefully read food labels to find out whatâs in their food and how itâs produced,â said Christine Bushway, Executive Director and CEO for OTA. âThe Sixth Circuit opinion made it clear that states cannot unduly restrict organic labels or consumersâ right to know how their food is produced, and the State of Ohioâs actions today make it clear that the fight to keep labels accurate by OTA, its members, farmers, and consumers was worth it.â […]

(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 companyâs 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, âI don’t need to tell you how important bees are to farmers who rely on pollination, and Remembee has great promise, pending approvals.â 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 […]

(Beyond Pesticides, October 25, 2011) Farmers in California and other states have begun planting bee-friendly flowers and shrubs to attract bees, whose populations have been severely declining in recent years under a complex set of circumstances. Farmers hope to sustain native bees and strengthen dwindling honey bee populations as well as lower their pollination costs. For many farmers that rely on bees to pollinate their crops, creating safe bee habitat and reducing chemical assaults can help stem the tide of declining pollinator populations. These efforts, organized by the Xerces Society, a Portland, Ore.-based nonprofit group, and other organizations are aimed to educate and help farmers boost dwindling wild pollinator populations needs to pollinate their crops. According to Xerces Society, as part of their pollinator conservation program, farmers and land managers are trained with the latest science-based approaches to reversing the trend of pollinator declines. California farmers are provided seeds for native plants like wild rose, aster, sage, manzanita, and other shrubs and trees to entice bees. New bee habitat can also reduce a farmer’s costs and alleviate the stress on honey bees. “For bees to thrive, they need a diverse diet, so we’re trying to bring more pollen diversity to […]

(Beyond Pesticides, October 13, 2011) A new report released by The Cornucopia Institute reveals the deceptive marketing practices in the natural foods industry by some of the nationâs largest breakfast cereal manufacturers, demonstrating the importance of the organic label in order to avoid synthetic pesticides and genetically engineered food. In some cases, companies are selling products contaminated with toxic agrichemicals and Monsantoâs genetically modified organisms while promoting them as ânatural.â The new report, Cereal Crimes: How âNaturalâ Claims Deceive Consumers and Undermine the Organic LabelââA Look Down the Cereal and Granola Aisle, explores in-depth this growing trend of marketing conventional foods as ânaturalâ to lure health-conscious and eco-conscious consumers and their shopping dollars. As Beyond Pesticides has pointed out in previous Daily News entries and our fact sheet, âMaking Sure Green Consumer Claims Are Truthful,â the report also acknowledges that there are no restrictions for foods labeled ânatural.â Unlike the organic label, no government agency, certification group, or other independent entity defines the term ânaturalâ on processed food packages or ensures that the claim has merit. Analysis by Cornucopia of wholesale and retail cereal and granola prices reveals that ânaturalâ products often are priced similarly or higher than equivalent organic […]

(Beyond Pesticides, October 6, 2011) Representatives of the International Federation of Organic Agriculture Movements (IFOAM) presented a special declaration October 1, 2011 to the United Nations (UN), requesting that the international organization commit all of its member nations to a world without genetically modified (GMO) foods and to identify existing GMO foods on product labels. The UN declaration was written in anticipation of the GMO Right2Know March which kicked off at the UN headquarters in New York on October 1 and will end at the White House on October 16. The UN delegation included IFOAM representatives, Joseph Wilhelm, founder of Rapunzel organic products and the force behind “Gene-Free America;â and his employees.” Maria-Luisa Chavez welcomed the delegation and accepted the declaration on behalf of the UN. She will pass it on to the president of the General Assembly, the main deliberative, policymaking and representative organ of the United Nations. Mr. Wilhelm believes that consumers have the right to know whether the food they buy is genetically altered. âTwenty percent of all manufactured foods in the U.S. contains genetically modified ingredients (GMO),â he said. âWe hope the Right2Know march will raise consumer awareness and influence U.S. legislators to require that labels […]

(Beyond Pesticides, October 4, 2011) In September, Bayer CropScience announced that it plans to phase-out its most acutely toxic pesticides, all remaining World Health Organization (WHO) class I products, by the end of 2012. While this is a positive development, Beyond Pesticides points out that other Bayer pesticides, such as its bee-killing insecticides imidacloprid and clothianidin, will remain on the market. Activists around the globe have mixed reactions to Bayerâs announcement, which comes over 15 years after Bayer first promised to phase-out its WHO Class I products. Philipp Mimkes of the Coalition Against Bayer Dangers based in Germany said, âThis is an important success for environmental organizations from all over the world who have fought against these deadly pesticides for decades. But we must not forget that Bayer broke their original promise to withdraw all class I products by the year 2000. Many lives could have been saved. It is embarrassing that the company only stopped sales because the profit margins of these chemical time bombs have fallen so much.â Acutely toxic pesticides with a WHO Class I rating are extremely toxic and present an immediate hazard to farmworkers and others in the vicinity of pesticide applications. The WHO estimates […]

(Beyond Pesticides, September 16, 2011) The U.S. Environmental Protection Agency (EPA) announced earlier this week that it is seeking public comments on a petition to ban atrazine, one of the most widely used herbicides in the United States. The call for comments was prompted by a petition submitted earlier this year by the group SAVE THE FROGS!, to ban the highly toxic chemical. The group, along its allies, delivered over 60,000 petition signatures and emails to EPA requesting an immediate ban. The group organized a rally at the steps of the EPAâs headquarters in Washington, DC back in April to raise awareness of the disappearance of amphibians and call for a federal ban on atrazine on the occasion of the international Save The Frogs Day. Amphibian populations worldwide have been declining at unprecedented rates, and nearly one-third of the world’s amphibian species are threatened with extinction. âNow that we have the EPAâs attention, we are a large step closer towards protecting our food supply, our drinking water and our wildlife from this known endocrine-disruptor,â says Kerry Kriger, PhD, founder and executive director of SAVE THE FROGS! âHowever, only a few percent of Americans have ever heard of atrazine, so raising […]

(Beyond Pesticides, September 14, 2011) A ruling last week by the European Court of Justice states that honey produced though cross-pollination with a genetically modified (GM) crop must be authorized as a GM product before being sold. The ruling means that the European Union (EU) will have to ban imported honey containing traces of pollen from GM crops that have not been approved for entry. Honey exports from the United States, Canada, Argentina or Brazil, countries with no regulations on the subject, will now be virtually impossible. In the ruling, which, in part, addressed the viability of GM pollen, delivered September 6, 2011, the Court observes, first, that the pollen in question may be classified as a GMO only if it is an âËorganismâ that is a âËbiological entity capableâ either of âËreplicationâ or of âËtransferring genetic material.’ If the pollen in question has lost all specific and individual ability to reproduce, it should be determined whether that pollen is otherwise capable of âËtransferring genetic material.â taking due account of the scientific data available and considering all forms of scientifically-established transfer of genetic material. The court concludes, âHoney and food supplements containing pollen derived from a GMO are foodstuffs produced […]

(Beyond Pesticides, September 6, 2011) Scientists in France have discovered that honey bees are at a higher risk of dying from infection by Nosema ceranae (N. ceranae) when they are exposed to low doses of insecticides. The results, presented in the journal PLoS ONE, support the theory that combining more N. ceranae with high pesticide content in beehives could contribute to colony depopulation. The French study, âExposure to Sublethal Doses of Fipronil and Thiacloprid Highly Increases Mortality of Honeybees Previously Infected by Nosema ceranae,â brought together researchers from the Laboratoire Microorganismes: GĂŠnome et Environnment and the Laboratoire de Toxicologie Environnment who utilized their respective skills in parasitology and toxicology to assess the effect of pathogen/toxin interactions on bee health. In the laboratory, the researchers chronically exposed newly emerged honey bees, some healthy and others infected with Nosema ceranae, to low doses of insecticides: fipronil and thiacloprid. They found that the infected bees died when they were chronically exposed to insecticides, even at sublethal doses, unlike the healthy bees. This combined effect on honeybee mortality was observed with daily exposure to extremely low doses (over 100 times less than the LD50 or dose needed to kill 50% of the sample population, […]
