(Beyond Pesticides, June 19, 2007) Scientists investigating a mysterious die-off of many of the nation’s honeybees are concentrating on pesticides and microorganisms as possible causes of the disorder, and some beekeepers are refusing to place their hives near chemically treated fields out of fear that pesticides may be contributing to the die-off. Scientists from Penn State University and the U.S. Department of Agriculture are leading the research into the disease, which has killed tens of thousands of bee colonies in at least 35 states. The die-off has threatened the livelihood of commercial beekeepers and strained fruit growers and other farmers who rely on bees to pollinate more than 90 flowering crops, including apples, nuts and citrus trees. After months of study, researchers cannot tie the ailment to any single factor. But scientists have zeroed in on a new, unnamed pathogen found in the dead bees, and on the role of pesticides, said Maryann Frazier, a senior extension associate in the university’s entomology department. David Hackenberg was the first beekeeper to report the disorder to Penn State last fall after losing nearly 75 percent of his 3,200 colonies. He has since rebuilt his business to 2,400 colonies, but now asks growers […]

(Beyond Pesticides, June 11, 2007) Scientists from the University of Nebraska-Lincoln (UNL) have discovered a gene that enables crops to tolerate being sprayed with dicamba. Citing previous experience with glyphosate resistant crops, environmentalists are concerned that this will increase use of a toxic herbicide while negatively impacting health and the environment. This new gene expands the range of genetically engineered (GE) crops available to farmers. The most popular are currently marketed as “Roundup Ready,” or tolerant of glyphosate, by Monsanto Company The discovery is being touted as a way to provide another option in areas where weeds have built up a resistance to glyphosate. Indeed, biochemist Don Weeks, who headed the UNL team, said, “Importantly, we think that this technology will help to extend the lifetime of the Roundup Ready technology. Some Roundup-resistant weeds have emerged in recent years, but working dicamba products into a weed-control strategy with Roundup could help counter that trend and lead to more complete weed control.” In fact, the dicamba-ready technology could appear in fields as part of a “stacked” seed, which is tolerant to both glyphosate and dicamba. Said Mr. Weeks, “It is highly likely that [Monsanto] would stack our gene with the Roundup […]

(Beyond Pesticides, June 4, 2007) The breakdown products (oxons) of the three most commonly used organophosphate pesticides in California’s agricultural Central Valley — chlorpyrifos, malathion and diazinon – are 10 – 100 times more toxic to amphibians than their parent compounds, which are already highly toxic to amphibians, according to a study released last Wednesday by scientists of Southern Illinois University, Carbondale, and the U.S. Geological Survey (USGS) Western Ecological Research Center. The results of the laboratory experiments on the toxicity of the three breakdown products were published in the journal Environmental Pollution. The title of the article is “Comparative toxicity of chlorpyrifos, diazinon, malathion and their oxon derivatives to larval Rana boylii.” “Since some of the parent pesticide compounds are already at concentrations sufficient to cause significant amphibian mortality in the Sierra Nevada, the higher toxicity of the breakdown products poses a serious problem,” said Gary Fellers, Ph.D., coauthor of the study. Donald Sparling, Ph.D., a research biologist and contaminants specialist at Southern Illinois University, and Dr. Fellers, a research biologist and amphibian specialist at the USGS Western Ecological Research Center in California, conducted laboratory tests to determine the acute toxicity – the lethal dosage causing death in 96 […]

(Beyond Pesticides, May 30, 2007) The Center for Biological Diversity today filed a lawsuit against the U.S. Environmental Protection Agency (EPA) for violating the Endangered Species Act (ESA). EPA has registered and allowed the use of 60 toxic pesticides in habitats for nearly a dozen San Francisco Bay Area endangered species without determining whether the chemicals jeopardize their existence. “Ending the use of known poisons in habitat for our most endangered wildlife is an appropriate 100th birthday tribute to Rachel Carson, who alerted us to the hazards of exposure to toxic chemicals almost half a century ago,” said Jeff Miller, conservation advocate with the Center. “Unfortunately the EPA has not learned from her legacy and still has no plan to adequately assess impacts while registering and approving pesticide uses that pose a clear and present danger both to imperiled species and human health.” At least 61 million pounds of pesticide active ingredients were applied in Bay Area counties from 1999 through 2005 ”” over 8.5 million pounds annually. Actual pesticide use may have been several times this amount since most home and commercial pesticide use is not reported to the state. Under the Bush administration, EPA has consistently failed to […]

(Beyond Pesticides, May 09, 2007) In a precedent-setting decision last week, Judge Charles Breyer ordered a complete environmental review of Monsanto’s genetically-altered alfalfa, making a final ruling that the U.S. Department of Agriculture’s (USDA) 2005 approval of Monsanto’s genetically engineered (GE) “Roundup Ready” alfalfa was illegal. The judge called on USDA to ban any further planting of the GE seed until it conducts a complete Environmental Impact Statement (EIS). In the decision, Judge Breyer in the Federal Northern District of California affirmed his preliminary ruling, which echoed the Center for Food Safety (CFS), Beyond Pesticides and other co-plaintiffs’ arguments in their lawsuit against USDA, that the crop could harm the environment and contaminate natural alfalfa. The ruling also requires Forage Genetics to provide the locations of all existing Roundup Ready alfalfa plots to USDA within 30 days. Judge Breyer ordered USDA to make the location of these plots “publicly available as soon as practicable” so that growers of organic and conventional alfalfa “can test their own crops to determine if there has been contamination.” “This permanent halt to the planting of this risky crop is a great victory for the environment,” said Will Rostov, a senior attorney for CFS. “Roundup […]

(Beyond Pesticides, May 1, 2007) More than a month after ordering a temporary halt to sales of genetically engineered (GE) alfalfa seeds, federal district court judge Charles Breyer is considering making the ban permanent, at least until the U. S. Department of Agriculture (USDA) completes a full Environmental Impact Statement (EIS) that confirms the seeds’ safety. (See Daily News of March 14 for Judge Breyer’s reasoning for siding against Monsanto’s team of lawyers, who were arguing that an EIS is unnecessary.) On why he was reluctant to reauthorize the planting of the GE crop, Breyer said, “It is not the court’s function to do an environmental impact study. That hasn’t been done, and I don’t know if the court ought to do it. The government ought to do it, and that is what I held.” Arguments by industry lawyers emphasized their belief that there is very little likelihood of damage being done by the GE alfalfa. Monsanto, which developed the seeds marketed as “Roundup Ready,” argued that there is an “extremely low risk” of conventional crops being contaminated, providing “appropriate stewardship measures” are taken. Monsanto Lawyer Janice Schneider even said, “There are some significant environmental and beneficial effects in Roundup […]

(Beyond Pesticides, March 22, 2007) A federal magistrate judge in Providence, Rhode Island fined The Little Rhody Beagle Club Incorporated and its former president $28,144 for illegally using pesticides, guns and steel leg-hold traps to kill birds and other animals that were preying on the club’s stock of rabbits, which are used to train beagles. According to a report in the Providence Journal, the charges resulted from a joint investigation by the U.S. Fish and Wildlife Service, the Environmental Protection Agency and the Environmental Police of the state Department of Environmental Management. Members of the dog club were chiefly targeting birds of prey, which they say ate the stocked rabbits. Most of the other, non-target birds, all of them quite common, died from insecticide poisoning. None of the birds the club killed are listed on an endangered species list. However, the birds are still protected, according to Tom Healy, a spokesman for the U.S. Fish and Wildlife Service. He explains that virtually all birds in North America, including the ubiquitous robin and the squawking crow, are migratory and fall under the protection of the Migratory Bird Treaty Act. The club, which is located in Warwick, and its former president, William […]

(Beyond Pesticides, March 14, 2007) On March 12, a federal judge ruled that the U.S. Department of Agriculture’s (USDA’s) 2005 approval of genetically engineered (GE) alfalfa is vacated and ordered an immediate halt to sales of the GE seed. The judge’s ruling follows a hearing held last week in the case brought by the Center for Food Safety (CFS) against USDA for approving GE alfalfa without conducting the required Environmental Impact Statement. In a press release issued by CFS, Will Rostov, senior attorney said, “We are pleased that the judge called for halt to sales of this potentially damaging crop.” Mr. Rostov continued, “Roundup Ready alfalfa poses threats to farmers, to our export markets, and to the environment. We expect the USDA to abide by the law and give these harmful effects of the crop full consideration.” The preliminary injunction ordered by Judge Charles Breyer in the Federal Northern District of California follows his ruling last month, finding that USDA violated national environmental laws by approving GE alfalfa without a full Environmental Impact Statement. In addition to barring seed sales, the injunction calls for a March 30, 2007, halt to planting of GE alfalfa by farmers who have already purchased […]

(Beyond Pesticides, March 9, 2007) New research shows that frogs are more sensitive to hormone-disturbing environmental pollutants than was previously thought. Male tadpoles that swim in water with environmentally relevant levels of such substances become females, according to the study that will be published in the scientific journal Environmental Toxicology and Chemistry (ET&C) in May (See University Press Release). The results may shed light on at least one reason that up to a third of frog species around the world are threatened with extinction, suggests the study. In a laboratory experiment by researchers in Sweden, two species of frogs, the European common frog (Rana temporaria) and the African clawed frog (Xenopus tropicalis), were exposed to levels of oestrogen (estrogen or chemicals mimicking the effect of estrogen) similar to those detected in natural bodies of water in Europe, the United States and Canada.The results were startling: whereas the percentage of females in two control groups was under 50 percent – not unusual among frogs – the sex ratio in the groups of tadpoles who matured in water dosed with different levels of oestrogen were significantly skewed. Even tadpoles exposed to the weakest concentration of the hormone were, in one of the […]

(Beyond Pesticides, March 7, 2007) On March 4, the United States Department of Agriculture (USDA) began a recall of a brand of long-grain rice seed because of possible contamination by genetically modified (GM) rice. The recall is one in a series of recent mishaps involving GM foods. The seed, known as Clearfield CL131, is manufactured by BASF Agricultural Products, a division of the world’s largest chemical company, BASF AG, and marketed by Horizon Ag. According to a USDA press release, Animal and Plant Health Inspection Service administrator Ron DeHaven, D.V.M., states, “The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is taking action to prevent the planting and distribution of a long-grain rice seed known as Clearfield CL131 because testing by a private company has revealed the possible presence of trace levels of genetic material not yet approved for commercialization.” The release continues to explain, “On March 1, 2007, BASF notified USDA’s Animal and Plant Health Inspection Service of independent laboratory test findings on 2005 CL131 registered rice seed . . . suggesting the presence of an unidentified and possibly regulated GM event.” In addressing this possibility, Dr. DeHaven states, “APHIS is conducting an investigation to determine […]

(Beyond Pesticides, March 1, 2007) In 24 states throughout the country, beekeepers have been shocked to find that bees have been inexplicably disappearing at an alarming rate, according to an article in the New York Times last week. This loss of honeybees threatens not only beekeeper livelihoods but also the production of numerous crops, including California almonds, one of the nation’s most profitable crops. Although the reasons for the honeybee disappearances are unknown, pesticides may be one of the culprits. “I have never seen anything like it,” David Bradshaw, a California beekeeper, said. “Box after box after box are just empty. There’s nobody home.” Last month he discovered that half of his 100 million bees were missing. Beekeepers have fought regional bee crises before, but this is the first national affliction. Bees are flying off in search of pollen and nectar and simply never returning to their colonies. And nobody knows why. Researchers say the bees are presumably dying in the fields, perhaps becoming exhausted or simply disoriented and eventually falling victim to the cold. As researchers scramble to find answers to the syndrome they have decided to call “colony collapse disorder,” growers are becoming openly nervous about the capability […]

(Beyond Pesticides, February 27, 2007) Pesticide run-off is polluting larger areas of the Great Barrier Reef than originally thought, leading scientists to call for better land care practices. For the first time a new series of satellite images show that sediment plumes, containing pesticides and other pollutants from Australian river systems, travel to the outer Great Barrier Reef, and beyond. Originally, it was thought that the plumes only affected the inner Great Barrier Reef Lagoon and the inner reef corals. The images, taken during the heavy rains in far north Queensland by the National Aeronautics and Space Administration’s MODIS satellite, show the pollutant plumes are travelling up to 135km offshore. Recent studies have shown agricultural chemicals are so poisonous to coral that it can prevent spawning, even when only present in minuscule amounts. This was found to consequently hinder the reef’s ability to regenerate and protect itself. Arnold Dekker, Ph.D., a scientist with the Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO), said the images would change the way scientists analysed reef pollution and that they showed land care practices needed to be improved in order to save the reef from destruction. “This is the first time it’s been really […]

(Beyond Pesticides, February 26, 2007) The United States’ largest dairy company, Dean Foods, has adopted a policy statement rejecting milk from cloned cows. The decision, which joins those of the organic dairy community to reject animal cloning, reflects the publics’ demand for foods free of genetic manipulation and chemicals. The food giant’s policy comes in the midst of the Food and Drug Administration’s (FDA) open comment period on its evaluation of the safety of animal cloning. While FDA is expected to determine animal products from clones are as safe as those from naturally produced animals, Dean Foods’ stance is a clear message that the market is not interested in purchasing them. The statement reads: “Based on the desire of our customers and consumers, Dean Foods will not accept milk from cows that have been cloned. If the FDA does approve the sale of milk from cloned cows, we will work with our dairy farmers to implement protocols to ensure that the milk they supply to Dean Foods does not come from cloned cows. “The U.S. Food and Drug Administration (FDA) is expected to conclude that milk from cloned cows is safe. Our decision not to accept this milk is based […]

(Beyond Pesticides, February 15, 2007) On February 13, a U.S. District judge ruled that the United States Department of Agriculture (USDA) violated federal environmental law by failing to conduct an environmental impact statement (EIS) on genetically engineered (GE) alfalfa seeds before deregulating them in 2005. Ruling on a lawsuit brought by environmental and farming groups, including Beyond Pesticides, Sierra Club and Center for Food Safety, Judge Charles R. Breyer found that USDA did not adequately defend its decision to forgo an EIS, while validating a number of the plaintiffs’ arguments. Alfalfa is the U.S.’s fourth-largest crop, and third most valuable. GE alfalfa seeds, primarily marketed by Monsanto as Roundup Ready, are engineered with a gene that causes them to be resistant to glyphosate. Among the plaintiffs’ concerns are contamination and cross-pollination between GE and natural crops, which can occur at a distance of up to two miles. Judge Beyer wrote, “Such gene transmission is especially likely in this context given the geographic concentration of alfalfa seed production.” He continued, “For those farmers who choose to grow non-genetically engineered alfalfa, the possibility that their crops will be infected with the engineered gene is tantamount to the elimination of all alfalfa; they […]

(Beyond Pesticides, February 1, 2007) Thirty-five years after the banning of DDT, extremely high concentrations of the pesticide are being found in fish caught in California’s Los Angeles county waters. According to a newly released federal survey by the National Oceanic and Atmospheric Administration (NOAA) and Environmental Protection Agency (EPA), the fish caught in the area contain the world’s highest-known DDT concentrations. The survey was conducted in order to update health advisories on which fish are unsafe to eat and to help EPA decide whether to attempt a costly operation to reduce continued contamination from a deposit of DDT on the ocean floor. The findings contradict the belief held by some scientists that DDT on the ocean floor has been breaking down into less-toxic compounds and would soon disappear from marine life. The contamination, most severe in the middle of San Redondo Bay, stems from a 100-ton deposit of DDT released by the Montrose Chemical Co. beginning in the late 1940s, which still covers several square miles of the ocean floor. The pesticide manufacturer had a plant near Torrance, California, from 1947 to 1971, releasing about 2,000 tons of DDT into county sewers that subsequently emptied into the ocean. The […]

(Beyond Pesticides, January 25, 2007) The commonly used herbicide atrazine has been found to have negative biological effects on phytoplankton-free-floating algae that forms the base of the food chain for aquatic animals. The study, published in the January 2007 issue of the journal Pesticide-Biochemistry and Physiology, indicates that protein levels in phytoplankton significantly decrease as a result of atrazine exposure, possibly having a negative affect on the nutritional levels of all aquatic species. The National Oceanic and Atmospheric Administration (NOAA) National Centers for Coastal Ocean Science researchers exposed five algal species to atrazine levels within the range of concentrations measured in the estuarine environment. In the majority of the species tested, the amount of energy converted into protein from photosynthesis, the process by which green plants convert water and carbon dioxide into organic materials using solar energy, significantly decreased with increased exposure. Atrazine is one of the most heavily used herbicides in the United States, applied to a wide variety of crops including corn, sorghum, sugarcane, pineapple, and Christmas trees, as well as turf. It acts as an inhibitor of photosynthesis by preventing the transfer of energy in certain plant species. NOAA researchers observed significant decreases in the size of […]

(Beyond Pesticides, January 18, 2007) A new study conducted in Costa Rica’s mountain forests indicates that surprisingly high concentrations of pesticides are accumulating far above the low altitudes at which they are used. Previously thought to be safe from pesticides applied to distant agricultural areas, some remote mountain forests of Costa Rica were found to have pesticide levels almost ten times greater than those in low-lying areas closer to farms and plantations. The study, led by University of Toronto, Scarborough professor Frank Wania, Ph.D., measured air and soil pesticide levels at 23 sites across Costa Rica in order to produce a model to predict potential accumulation of chemicals at high altitudes. The insecticide endosulfan and the fungicide chlorothalonil were found in the largest concentrations, with up to 1 part per billion (ppb) of chlorothalonil and 3 ppb endosulfan in soil. The high concentrations can be explained by a process in which polluted air above the farms and plantations is pushed up into the mountains, where it then cools and becomes polluted rainwater or fog. The hydrophilic nature of modern pesticides makes the occurrence of this phenomenon much more likely; as Crispin Halsall, Ph.D., of Lancaster University (U.K.) explains, “Most currently […]
