(Beyond Pesticides, May 13, 2014) After pressure from environmental organizations, the U.S. Fish and Wildlife Service (FWS) dropped plans to spray the synthetic insecticide methoprene in favor of a biological control material  to kill mosquitoes breeding on a national wildlife refuge on the southern Oregon Coast. Several states have banned methoprene due to the chemical’s environmental impacts. The unfolding of this decision illustrates that least-toxic alternatives to manage mosquitos are effective and much safer for the environment. A major restoration at the Bandon Marsh National Wildlife Refuge in 2011 inadvertently created a number of shallow water pools, a perfect habitat for mosquito larvae. Unprecedented swarms of mosquitoes appeared last year, which drove away campers from Bullards Beach State Park and harassed golfers at local courses. FWS did not take into account that this restoration project could create mosquito habitat and initially released a plan to manage mosquitos with methoprene and mineral oil. The insect conservation group Xerces Society, the Center for Food Safety, and others urged the agency to reconsider, arguing the pesticides were a threat to the food chain and the mosquitoes, Aedes dorsalis, did not spread human diseases such as West Nile virus. In a supplemental environmental assessment […]

(Beyond Pesticides, May 7, 2014) A new report from the California Department of Public Health finds 36 percent of public schools in the state have pesticides of public health concern applied within a quarter mile of the school. Persistent and toxic pesticides like chlorpyrifos, methyl bromide, and malathion are among the pesticides found to be applied near schools. The report also finds that Latino children are also more likely to attend schools near areas with the highest use of pesticides of concern. The report, “Agricultural Pesticide Use near Public Schools In California,” released this month, looked at 2,511 schools in the 15 California counties with the highest overall use of farm pesticides in California for 2010, and finds that counties in the southern part of the Central Valley had the most schools near farms where pesticides were applied. Fresno County had the highest number of schools —131 — with pesticides applied nearby. Five percent of schools are within a quarter mile of where the highest volumes of pesticides are used: 2,635—28,979 pounds of active ingredient. Latino children are 46 percent more likely than white children to attend schools where pesticides of concern were applied nearby. The report’s findings are being […]

(Beyond Pesticides, April 30, 2014) A new report, released this week by author  Michele Simon  and Friends of the Earth  documents the tactics used by Bayer and other pesticide companies to delay regulatory action on neonicotinoid pesticides —a key contributor to bee declines. The report identifies public relations tactics reminiscent of those used by the tobacco industry, is now being used by Bayer, Syngenta, and Monsanto. Meanwhile, a Congressional hearing on pollinator health, with a panel dominated by industry, ignored the risks pesticides pose to pollinators, and failed to address sustainable solutions to bee decline. The report,  Follow the Honey: 7 Ways Pesticide Companies Are Spinning the Bee Crisis to Protect Profits,  uncovers the deceptive public relations tactics used by industry giants Bayer, Syngenta and Monsanto, to deflect blame from their products’ contributions to bee declines. The products in question are the chemicals now widely used for seed treatment  —neonicotinoids— as well as on residential sites. They are highly toxic to bees and have been linked to bee decline. Last year, the European Union banned the three most widely used neonicotinoids —imidacloprid, clothianidin and thiamethoxam— based on strong science indicating these insecticides can kill bees outright and make them more […]

(Beyond Pesticides, April 24, 2014) Reports of honey bee deaths have been emerging around the nation: from bee deaths in California’s almond groves and ”˜mysterious’ road-side bee deaths in Oregon, to astronomical overwintering losses in Ohio. The reports are intensifying the ecological crises of Colony Collapse Disorder (CCD) ””a phenomenon typified by the mass abandonment of hives and bee die-off. CCD poses significant issues for many agricultural crops, such as almonds, apples, cherries and blueberries, that are almost completely reliant on honey bees for their pollination services. In California, a total of 80,000 dead or damaged bee hives were reported after pollinating almond trees in the San Joaquin Valley, a region that is known for its agricultural productivity. Beekeepers have pointed to pesticides as the primary culprit. Almond pollination in California requires an army of 1,300 commercial beekeepers from around the nation. However, this year beekeepers have seen higher damages to hives than usual. Damage to the honey bee hives this spring has been so pronounced that the U.S. Environmental Protection Agency (EPA) convened an impromptu meeting with beekeepers in Los Banos, California. The meeting brought together 75 beekeepers who testified that 75 percent of their hives showed severe damage […]

(Beyond Pesticides, April 24, 2014) France’s lower house of parliament passed a bill last week banning the cultivation of all strains of genetically engineered (GE) corn within its borders, even those strains that might not yet be approved within the European Union (EU). The law follows a decree adopted last month, which targeted the only GE crop permitted for cultivation in the EU””Monsanto’s insect-resistant MON810 corn. Back in the U.S., Vermont became the first state to pass a  bill requiring the labeling of food containing GE ingredients  (You can read the House bill as it was introduced here and the Senate amendments to this bill here). The bill, which the Governor said he will sign, passed by large majorities in both houses of the legislature and does not contain a trigger provision similar to laws adopted in Connecticut and Maine  –with a  requirement that  similar action is taken in contiguous states before the law goes into effect. The action in France is not  the first time it has closed the door on MON810, even in the face of its highest court’s rulings that similar bans did not have sufficient justification. Yet, undaunted by these defeats the French General Assembly went […]

(Beyond Pesticides, April 18, 2014) Last week the Vermont state Senate voted 28-2 to authorize the mandatory labeling of foods made with genetically engineered (GE) ingredients. The bill, H.112, “An Act Relating to the Labeling of Food Produced with Genetic Engineering,” passed the Vermont House of Representatives back in May, and now goes back to the House for approval before moving to the Governor. Vermont’s legislation does not include a “trigger clause,” which is contained in  labeling bills passed last year in Maine and Connecticut  that, before  going into effect,  require other states in the New England region (including one boarding state) with an aggregate population of 20 million to pass similar laws. If the last hurdles in the state legislature are cleared and the bill is signed by Governor Peter Shumlin (D), Vermont’s labeling law would not allow manufacturers to describe any food containing GE ingredients as “all natural” or “natural.” Processed foods that contain a product or products with GE would be required to display in clear and conspicuous language the words, “partially produced with genetic engineering” or “may be partially produced with genetic engineering.” But even if passed, Vermont’s bill faces numerous challenges from the deep pockets […]

(Beyond Pesticides, April 22, 2014) As we reflect on the beauty and wonder of the natural world this Earth Day and seek to restore  and preserve  the intricate web of life on the planet, we face an urgent need to stop ongoing toxic chemical contamination.  The hard truth of our time is that the natural world on which life depends  is under grave threat from numerous toxic insults resulting from mechanized and industrial human activity. Massive die-offs of beneficial organisms, increased rates of autoimmune diseases, endocrine disrupting and transgenerational chemical effects, and widespread pollution of our air and waterways —all linked to pesticides and other toxic chemicals, establish the critical  need  to adopt organic standards in sync with ecosystems. This Earth Day we ask you to spread awareness of toxic chemicals that pollute the environment. Get active to safeguard your community and the surrounding environment from toxic insults: teach your neighbors how to maintain their land without toxic pesticides, protect honeybees from neonicotinoids insecticides, aquatic species from endocrine disrupting chemicals, and the streams, lakes, and rivers we all depend on from the widespread use of harmful synthetic pesticides and fertilizers. Beyond Pesticides has the tools needed to increase environmental awareness […]

(Beyond Pesticides, April 18, 2014) Test results have confirmed that the charismatic mountain lion named P-22 ””that frequently roams the hills of the San Gabriel Mountains surrounding Los Angeles, California”” has been exposed to highly toxic rat poisons. When remote cameras in Griffith Park caught images of the puma, state park officials saw a thin mangy cat, far different from the majestic shots taken months ago by National Geographic against the Hollywood sign as a backdrop. Upon performing blood testing analysis, they found that P-22 had been exposed to anticoagulant pesticides, stoking the debate around rodenticide use, as further research suggests that these pesticide poisonings are a common occurrence. Researchers already know of the link between pesticides and mange””parasitic mites which burrow into the skin or hair follicles causing bald spots, scabbing and sore, which left untreated has contributed to the death of wild and domestic animals. Previous research by the National Park Service (NPS) has shown that bobcats that have ingested rodenticide are much more likely to suffer from mange. While the cougar has been treated with topical ointments for mange, and a dose of vitamin  D with vitamin  K as an antidote to the rat poisons, it is […]

(Beyond Pesticides, April 17, 2014) Rep. Mike Pompeo (R-KS) recently introduced H.R. 4432, a bill that would give full authority of  genetically engineered (GE) labeling to the Food and Drug Administration, which now favors a voluntary approach to the issue.  The bill is designed by industry to undercut a growing number of states that are taking on GE labeling by preempting state authority. The bill is being fought by environmental and food safety groups that are backing federal legislation that would label all GE ingredients. H.R. 4432, or what is being dubbed as the “Deny Americans the Right-to-Know Act” (DARK Act) by activists, would dramatically change food labeling by giving the preemptive authority of labeling GE ingredients to the Food and Drug Administration (FDA). The act will prevent states from adopting their own GE labeling laws, allow food companies to put a “natural” label on products that contain GE ingredients, and prevent the FDA from requiring companies to label GE ingredients and continue its current “voluntary” labeling policy. This codification of a voluntary labeling standard clearly does not meet consumers growing demands for more information. In the 13 years that FDA has allowed companies to voluntarily label genetically engineered foods, […]

(Beyond Pesticides, April 16, 2014) The U.S. District Court of Hawaii granted a Motion to Intervene jointly presented by Center for Food Safety (CFS) and Earthjustice on behalf of several community non-profit groups. The order allows the groups to participate in a lawsuit filed by Syngenta and other pesticide companies challenging Kauai’s County Ordinance 960, which  establishes a  county program to monitor pesticide use and genetically engineered (GE) crops. The federal order allows the groups to defend the County of Kauai’s 2013 pesticide disclosure law against the pesticide companies’ legal challenge. The non-profit groups intervening include Center for Food Safety, Surfrider Foundation, Pesticide Action Network North America, and Ka Makani Ho”˜opono. Ordinance 960 (formerly known as Bill 2491) provides residents of Kauai public access to information related to the application of pesticides used in experimental and commercial agricultural operations within the County of Kauai. It also affords County residents and their environment greater protection from and information about potential pesticide drift and the impact of growing experimental GE crops on Kauai. The Kauai County Council voted to enact Ordinance 960 in November 2013, overriding the Mayor’s veto. The Ordinance 960 is set to take effect in August. Local leaders crafted […]

(Beyond Pesticides, April 15, 2014) A new study released last week by the National Park Service on contaminant use in Alaska, found traces of pesticides in fish ””pesticides which have long been banned and likely never been used within the Alaskan wilderness areas. Researchers examined three Alaskan parks renowned for their remote, pristine and protected wilderness ””Lake Clark National Park, Wrangell-St. Elias National Park and Katmai National Park”” only to find that contaminants, including PCBs at concentrations exceeding those in the lower 48 states. The study, Contaminants of Emerging Concern in Fish from Western US and Alaska National Parks””Spatial Distribution and Health Thresholds, published in the Journal of the American Water Resources Association, sought to compare contaminant level found within fish across the nation. Generally, researchers found that Alaskan fish were more likely to have traces of older chemicals, while those in the lower 48 tended to be dominated by newer chemicals. The most commonly detected chemicals are PCBs, endosulfan, sulfate and p,p’-DDE, a breakdown product of DDT.  Some of these long-banned chemicals actually exceed the U.S. Environmental Protection Agency’s (EPA) guidelines for human subsistence on fish and wildlife. Among those exceeding acceptable levels, dieldrin, chlordane, and p,p’-DDE have been […]

(Beyond Pesticides, April 14, 2014) Bowing to political pressure and agrochemical industry opposition Sri Lanka’s government has taken a step back from its original decision to place a ban on one of the most widely used herbicides worldwide ””glyphosate. Scientific evidence has tied glyphosate to the incurable, deadly kidney disease that has afflicted thousands of Sri Lankans. The delay marks a setback in efforts by scientists and activists to remove from the shelves  a chemical widely used on tea and rice paddy plantations in Sri Lanka.  The decision to ban the chemical was initiated following the publication of a scientific report demonstrating that kidney disease was primarily caused by glyphosate. The report provides a summary of existing scientific information demonstrating kidney failure among farmers who were exposed to the popular herbicide. Indeed lead author Channa Jayasumana, PhD. explains that glyphosate bonds with toxic heavy metals in the environment such as cadmium and arsenic, forming stable compounds that are consumed in food and water and do not break down until they reach the kidneys. “Glyphosate acts as a carrier or a vector of these heavy metals to the kidney,” said Dr. Jayasumana. The chemical was initially created as a chelating […]

(Beyond Pesticides, April 11, 2014) Connecticut State Senate bill no.443, an act that bans the sale of genetically engineered (GE) grass seeds, passed the state Senate on Wednesday by a vote of 25-11. The bill shows Connecticut legislators are taking seriously the risks that increased pesticide use in residential areas pose to the health of the states residents, especially children, and pets. The bill will ban the sale, use, and marketing of lawn or turf seeds that are genetically engineered to be resistant to pesticides. The GE grass seed that is being developed by Monsanto and Scotts is currently not available in consumer markets and is being tested by Scotts employees in their front yards. The bill may face stronger challenges from Connecticut’s House as it is unclear if the House speaker, J. Brendan Sharkey, D-Hamden, will call for a vote on the bill before the session ends May 7. One of the major concerns  the bill addresses  is that allowing GE grass seeds for consumer use would lead to dramatic increases in residential pesticide use. “So you will spread this pesticide all across your lawn, back and forth, on your lawn,” said Sen. Edward Meyer, D-Guilford, as quoted in […]

(Beyond Pesticides, April 4, 2014) Habitat destruction, pesticide contamination, agricultural intensification and climate change threaten 24 percent of Europe’s bumblebees, according to research conducted by the International Union for Conservation of Nature (IUCN) and funded by the European Commission. The study is part an ongoing project called European Red List of pollinators, with contribution from experts of the “Status and Trends of European Pollinators”  (STEP) project,  which assesses the conservation status of all bees ””approximately 2000 species”” occurring throughout Europe. The study concludes that almost half of the 68 species in the European Union (EU) are in decline, including those at risk of extinction. Of these, a total of 16 species are listed as at risk according to the IUCN’s Red List of Threatened Species, which represents the world most trusted authority on the conservation status of species. In comparison, only 13 percent of bumblebee populations are increasing. “We are very concerned with these findings. Such a high proportion of threatened bumblebees can have serious implications for our food production,” says Ana Nieto, European Biodiversity Officer of IUCN and coordinator of the study. “Protecting bumblebee species and habitats, restoring degraded ecosystems and promoting biodiversity-friendly agricultural practices will be essential to […]

(Beyond Pesticides, April 2, 2014) Just last week it was announced that California ruled to remove from store shelves several rodenticide products identified by the U.S. Environmental Protection Agency (EPA) as unsafe for children and wildlife.  The maker of these products, Reckitt Benckiser, aggressive in  challenging regulators who want to restrict the company’s loose bait products,  is  suing  California to stop it from acting. The state’s new restriction on retail sales of second-generation anticoagulant rodenticides, due to take effect July 1, 2014, seeks to protect wildlife and pets from accidental poisoning from rat poisons. Reckitt Benckiser is also embroiled in challenging EPA’s decision to remove these products from the national marketplace for failure to meet federal standards. The California’ Department of Pesticide Regulation (CDPR) ruled last week that second generation anticoagulant rodenticides, including the chemicals brodifacoum, bromadiolone, difenacoum, and difethialone, found in d-CON brand products, must be classified as California-restricted materials, and only allowed to be used by certified pesticide applicators. This follows EPA’s 2013 issuance of a Notice of Intent to Cancel the registrations of rodenticide products that do not meet the agency’s new mitigation measures to reduce poisonings to children and wildlife. However, manufacturer of d-CON, Reckitt […]

(Beyond Pesticides, April 1, 2014) Earthworms that make their home in contaminated soil do so at a significant cost, according to French and Danish researchers. Results of the study, “Acclimation of earthworms to chemicals in anthropogenic landscapes, physiological mechanisms and soil ecological implications,” found that earthworms exposed to fungicides in conventionally farmed soil were at a stark disadvantage to worms in land managed organically. Earthworms exposed to the fungicide product Opus, containing active ingredient epoxiconazole, were able to detoxify the chemical, but gained half as much weight as worms from an organic farm, where their population was also 2 to 3 times higher. The study observed the adaptation capability of earthworms by comparing the response from those in land managed conventionally for 20 years to those in land managed organically for the same amount of time. Researchers focused on the metabolic changes seen in each group of worms after exposure to epoxiconazole. According to the study’s authors, “The fungicide increased metabolism rate in the worms, both the adapted worms and the not adapted worms. In the not adapted worms we saw that their energy reserve of glycogen was used faster. Contrastingly, only in the adapted worms we saw that amino […]

(Beyond Pesticides, March 27, 2014) — A report released by Center for Food Safety (CFS) this week refutes claims that a dangerous class of insecticides, neonicotinoids, bring greater benefits than costs to farmers. In the report, Heavy Costs: Weighing the Value of Neonicotinoid Insecticides in Agriculture, researchers analyzed independent, peer-reviewed, scientific literature to answer the simple question: Are neonicotinoid insecticidal seed treatment products beneficial or not? Neonicotinoids, the pesticides in question, are a class of systemic insecticides. Despite numerous studies linking these insecticides with bee kills, colony collapse, and weakened pollinator immune systems, the U.S. Environmental Protection Agency (EPA) continues to operate under an alarmingly slow pesticide registration review process, one that extends to 2018 and will most likely fail to appropriately apply the appropriate standard of review for pesticide registration. Under that standard of review, EPA should not approve a pesticide that poses unreasonable risks to “man or the environment,”  taking into account economic, social, and environmental costs and benefits.  Unfortunately, economic costs and benefits usually become the sole factor. Because of EPA’s failure to appropriately weigh these costs and benefits, honey bees and other pollinators have been bearing the brunt of the costs without recognition of the […]

(Beyond Pesticides, March 26, 2014) Conservation and food-safety groups filed a formal notice of intent to sue the U.S. Environmental Protection Agency (EPA) on Monday for failing to protect hundreds of endangered fish, butterflies and other species from a new, toxic pesticide, cyantraniliprole. The suit claims EPA violated the Endangered Species Act (ESA) by approving the widespread agricultural and residential use of the new pesticide in January without input from the U.S. Fish and Wildlife Service and National Marine Fisheries Service, the two federal agencies in charge of protecting endangered species. The Notice of Intent to Sue is being filed by the Center for Biological Diversity,  Center for Food Safety, and Defenders of Wildlife. Cyantraniliprole, a new, systemic insecticide, was formally registered by the EPA earlier this year. Despite evidence that cyantraniliprole is toxic to honey bees, EPA’s registration document for cyantraniliprole finds that, “There is a reasonable certainty that no harm will result from aggregate exposure to the pesticide residue.” According  to EPA’s assessment the pesticide is also slightly to very highly toxic to aquatic organisms. Comments from beekeepers and concerned groups, including Beyond Pesticides, urged EPA not the grant registration, given the toxic nature of the pesticide and […]

(Beyond Pesticides, March 25, 2014) Highly toxic rodenticides linked to the poisoning of pets, wildlife and young children will no longer be allowed on store shelves in California starting July 1 of this year. According to rules adopted last week by California’ Department of Pesticide Regulation (CDPR), “second generation anticoagulant rodenticides,” including the chemicals brodifacoum, bromadiolone, difenacoum, and difethialone found in d-CON brand products, will be classified as California-restricted materials, and only allowed to be used by certified pesticide applicators. Attempts by the U.S. Environmental Agency (EPA) to remove these products from store shelves nationwide stalled last year after the manufacturer of d-CON rodenticides, Reckitt Benckiser, sued the agency to delay implementation of the cancellation process. In July of 2011, the California Department of Fish and Wildlife requested CDPR restrict the use of anticoagulant rodenticides due to numerous incidents involving direct and indirect poisoning of wildlife. Anticoagulants impair blood clotting and eventually cause internal bleeding in target animals. However, rodents can feed on poisoned bait multiple times before death (some are even resistant to the chemicals now), and as a result their carcasses may contain residues that are many times the lethal dose. Poisoning can occur to nontarget species when […]

(March 24, 2013 Beyond Pesticides) A study by an entomologist at Iowa State University in Ames Iowa found that western corn rootworm is now resistant to two varieties of Bt-incorporated genetically engineered (GE) maize and that resistant insects are likely to be cross-resistant. This study adds to the growing scientific literature that shows insect resistance to Bt crops is making certain GE technologies obsolete, which could lead to an increase in insecticide use. The study, Field-evolved resistance by western corn rootworm to multiple Bacillus thuringiensis toxins in transgenic maize, conducted by a team led by Aaron Gassmann, PhD, adds to the growing scientific literature that that finds western corn rootworm  is resistant to varieties of Bt-incorporated GE maize. In 2009, farmers in Iowa observed severe injury to Cry3Bb1 maize —one of the three varieties of Bt-incorporated GE maize- from larval western corn rootworm in the field. Subsequent laboratory assays reveal that this injury is associated with rootworm resistance to  Cry3Bb1. This study finds that injury to Cry3Bb1 maize because of rootworm resistance persisted beyond 2011 and expanded to include mCry3A maize, a second variety of Bt-incorporated GE maize. Laboratory analysis of western corn rootworm from these fields finds resistance to […]

(Beyond Pesticides, March 19, 2014) Ruling on a  challenge by biotech industry interests, the Colorado Supreme Court on March 13 authorized the Right to Know Colorado ballot initiative to label GMO foods, clearing the way to begin collecting over 86,000 signatures needed for a 2014 statewide ballot measure. In overturning a major challenge by the biotech industry, pesticide, and grocery interests to a statewide GMO labeling ballot initiative, the Colorado State Supreme Court affirmed Colorado consumer’s right to determine whether the presence of genetically engineered foods should be labeled on food packaging. The State Supreme Court ruling allows the Right to Know Colorado campaign, a grassroots effort established by local residents to achieve mandatory labeling of genetically engineered (GE) ingredients ( commonly known as GMOs) in foods, to begin circulating petitions for signatures to place the initiative on the November 2014 ballot. Colorado requires 86,105 valid signatures to be submitted by early August to place an initiative on the ballot. Once on the ballot, Colorado will vote on whether labeling should be required for GE foods. The campaign plans to partner with local farmers, farmers markets, moms, faith-based organizations, natural, organic and non-GE food retailers, and other health, sustainability and […]

(Beyond Pesticides, March 12, 2014) As many as 700 birds have been found dead in a wildlife reserve in New South Wales, Australia. Preliminary tests reveal that the pesticide, fenthion, was the cause of death for many little correlas, galahs and sulphur-crested cockatoos found over the past two weeks. Certain uses of fenthion for home gardens and a range of agricultural uses were scheduled for suspension by the Australian Government, but a few months ago fenthion use, long associated with bird kills, was extended for another year. For the past two weeks, dead birds have been found all along a mile of Troy Reserve on the Talbragar River, in New South Wales, Australia. Testing of samples from the dead birds indicated fenthion, an organophosphate insecticide highly toxic to birds, as the most likely cause of the deaths. Volunteers helped gather the carcasses to prevent raptors, such as whistling kites and tawny frogmouths, from feeding on the poisoned carrion. About 30 sick birds, including two kites, have been so far been rescued. Locals found the first deaths on February 27 but were initially prevented from collecting the carcasses out of concern about possible bird flu. About 200 dead birds were found […]
