(Beyond Pesticides, February 6, 2008) EPA has submitted a draft Notice of Intent to Cancel (NOIC) for all carbofuran registrations to EPA’s Scientific Advisory Panel (SAP). Carbofuran is a highly toxic insecticide used on field, fruit and vegetable crops and has long been the subject of controversy and a series of use restrictions that environmentalists have decried as too limited. EPA has opened a docket containing the materials provided to the SAP that is convening on February 5-8. The SAP will review the scientific assessment underlying EPA’s NOIC for carbofuran and respond to questions posed by the agency related to the impact on health and the environment of the proposal. The docket number is EPA-HQ-OPP-2007-1088; view docket information.This action is the result of an interim reregistration eligibility decision reached by EPA in August 2006, in which the agency found all products containing carbofuran ineligible for reregistration. FIFRA requires that EPA consult the SAP before issuing an NOIC. The SAP meeting, which is open to the public, will be held at an EPA Office of Pesticide Programs conference room at One Potomac Yard in Arlington, Virginia.Carbofuran was first registered in the United States in 1969 and is classified as a restricted […]

(Beyond Pesticides, February 1, 2008) Two studies of nutrient levels in the Gulf of Mexico, one by the United States Geological Survey and the other by Yale and Louisiana State University researchers, have recently been published. Both reveal that nutrient levels in the Mississippi watershed have risen significantly, and that the growing “dead zone” in the Gulf can largely be attributed to changes in agricultural practices in the last half-century. The first report, entitled “Differences in Phosphorus and Nitrogen Delivery to The Gulf of Mexico from the Mississippi River Basin,” modeled nutrient delivery to the gulf in order to determine the watershed management practices required to reduce nitrogen discharge by 30 to 45 percent, and the size of the dead zone in half, by 2015. 13 states in the midwest contributed the overwhelming majority of inputs to the watershed. The largest contributor to nitrogen pollution of the watershed came from corn and soybean production, which also contributed to a quarter of the total phosphorus runoff into the Gulf. The researchers concluded that future management strategies must “include recognition of important differences in the agricultural sources of N[itrogen] and P[hosphorus] . . . and better control of both N and P […]

(Beyond Pesticides, November 30, 2007) Seven years ago, the introduction of genetically modified (GM) sugar beets, along with other crops like potatoes and rice, was shelved at fears that consumers would not support their use. Sugar beets, which produce about half of the United States sugar (almost all of which is used domestically), are used in foods like candy, cereal, and baking products. The failure of the GM beet’s initial introduction was based on unwillingness from companies like Hershey and Kellogg to provoke consumer protests. Now, the marketplace seems to have changed enough that such big sugar-buying companies are less hesitant to buy Monsanto’s “Roundup Ready” beet (which are tolerant of Roundup’s main ingredient, glyphosate). According to Kellogg spokeswoman Kris Charles, her company “would not have any issues” buying them because “most consumers are not concerned about biotech.” “Basically, we have not run into resistance,” said American Crystal Sugar president David Berg of the switch. “We really think that consumer attitudes have come to accept food from biotechnology.” Most other companies, including Hershey and Mars, are refusing to comment on the subject, which has kept these developments quiet until recently. Despite the corporate perception of public opinion on GM crops, […]

(Beyond Pesticides, October 16, 2007) Corn, genetically engineered (GE) to tolerate the pesticide Bacillus thuringiensis (Bt), has been found to harm non-target aquatic insects and disrupt the connected food web. A new study by researchers at Indiana University, funded by the National Science Foundation and published in Proceedings of the National Academies of Sciences, suggests that the crop, which has been licensed for use since 1996, poses an unforseen risk to aquatic ecosystems. According to the study, roughly 35 percent of American corn acreage is Bt corn. Pollen and other parts of the plants are travelling much farther than the fields in which they are planted, carrying Bt toxins through watersheds and being consumed by close relatives of the corn’s targeted pests. Caddisflies experience high mortality and stunted growth as a result of exposure. As researcher Todd V. Royer observed, they “are a food resource for higher organisms like amphibians and fish. And, if our goal is to have healthy, functioning ecosystems, we need to protect all the parts. Water resources are something we depend on greatly.” This effect went unnoticed for ten years because the Environmental Protection Agency (EPA), in its registration trials, tested Bt on a crustacean, rather […]

(Beyond Pesticides, September 13, 2007) As the debate rages on the impacts of growing plants, including food crops, for biofuel, the environmental impacts of growing practices and energy costs are consistently raised with concern. University of Minnesota scientists, in releasing a report, “Environmental, economic, and energetic costs and benefits of biodiesel and ethanol biofuels,” in the July 15 2007 online Proceedings of the National Academy of Sciences, say that an analysis of the “full life cycles of soybean biodiesel and corn grain ethanol shows that biodiesel has much less of an impact on the environment” and causes less pesticide pollution in its production. It can be argued that if crops are to be grown for fuel, they should only be grown organically to reduce energy consumption and sequester atmospheric carbon at the highest possible rates (see “The Organic Farming Response to Climate Change“). A September 9, 2007 New York Times article, “Mali’s Farmers Discover A Weed’s Potential Power,” cites a plant found in Mali, called jatropha, that grows under the harshest soil and weather conditions without any pesticides and little fertilization and is an ideal source for biofuel. The author of the Times piece describes the plant with “poisonous black […]

(Beyond Pesticides, August 10, 2007) As the face of agriculture in America changes with rising prevalence of herbicide-tolerant crops, farmers in Mississippi and Arkansas are also facing challenges caused by increased herbicide resistance. A recent press release by the Delta Research and Extension Center (DREC) blames glyphosate-resistant weeds for increased costs in Mississippi, while a leading British researcher will work with the University of Arkansas Cooperative Extension Service to determine the impact that the same weeds will have on farming in Arkansas. According to DREC’s release, a “concern for agricultural production in the Mississippi Delta is the increase of weeds resistant to the herbicide glyphosate . . . DREC rice weed scientist Jason Bond said that both glyphosate-resistant horseweed and volunteer Roundup Ready soybeans have become problem weeds for Mississippi rice production.” Research associate Tom Eubank also said, “Glyphosate-resistant horseweed, ryegrass and pigweed are concerns in Mississippi Delta soybeans.” Meanwhile, Arkansas farmers are noticing a similar trend: the increased use of glyphosate on Monsanto’s “Roundup Ready” crops is leading them to map the future of herbicide-resistant weeds and consider alternative weed management programs. According to the High Plains/Midwest Agricultural Journal, “researchers believe that if pigweed, or Plamer amaranth, can’t be […]

(Beyond Pesticides, August 3, 2007) Maine is no longer the only state to prohibit the use of genetically altered corn. Despite concern from the organic farming community, Maine joined the rest of the nation last Friday when the Board of Pesticide Control (BPC) ruled to allow Bacillus thuringiensis (Bt) corn to be grown and sold in the state of Maine. With the aim of reducing the use of hazardous pesticides, the BPC registered Bt corn products from Dow AgroSciences, Pioneer Hi-Bred International and Monsanto to be grown for animal feed. Bt corn is genetically modified to produce its own pesticide, a naturally occurring toxin that protects against a combination of insects. Organic growers caution that overuse of the crop will lead to insect resistance to the Bt toxin, which is widely sprayed on organic crops. “I think it might very well be a short-term solution and farmers will be forced to use more pesticides in the future,” said Board member Lee Humphreys, a market gardener. She warned that there are too many unknowns about the genetically modified corn, such as its long-term effect on the soil and in creating resistant bugs. In addition, the safety of consuming milk and beef […]

(Beyond Pesticides, July 11, 2007) According to the U.S. Department of Agriculture’s (USDA) Economic Research Service, the number of genetically engineered (GE) crop acres by U.S. farmers has skyrocketed since their introduction in 1996, despite resistance from consumers and concerns about agricultural and environmental impacts. Because the U.S. does not require GE crops to be labeled, the only way to be sure you are not consuming these products is to buy organic, which forbids the use of GE technologies. Soybeans and cotton genetically engineered with herbicide-tolerant traits have been the most widely and rapidly adopted GE crops in the U.S., followed by insecticide-incorporated cotton and corn. The chart below shows the growth of GE soybeans, cotton and corn since 1996. (HT = modified to be herbicide tolerant, Bt = modified to produce the insecticide Bt) Since 2000, use of HT soybeans has increased from 54% of acreage planted with the crop to 91% in 2007. GE corn varieties, both HT and Bt, have increased from 25% to 73%. Cotton varieties, both HT and Bt, have increased from 61% to 87%. In addition to the lack of information available on the long-term safety of GE products, Beyond Pesticides is concerned with […]

(Beyond Pesticides, July 3, 2007) A scientist at the Minnesota Pollution Control Agency (MPCA) has filed a whistleblower lawsuit in federal court, arguing that he was first not allowed to share his research with a legislative panel, and then fired for it. Hydrologist Paul Wotzka, who worked for the state Agriculture Department for sixteen years before leaving to join MPCA in October, had been slated to testify about the rise in atrazine levels in Whitewater State Park, which have exceeded recommended levels for several area species. Atrazine, which has been linked to cancer, birth defects, neurotoxicity, endocrine disruption and a variety of other health and environmental effects and has been banned by the European Union, is a widely used agricultural herbicide.. Mr. Wotzka said in his lawsuit, as well as publicly, that this rise in atrazine in Minnesota waterways was due to increased row-crop agriculture in the region and the the Agriculture Department’s support of corn for ethanol. In his lawsuit, Mr. Wotzka is asking for $75,000 and to return to his position with MPCA. He claims that he was put on investigative leave, “related to missing data that is property of the State of Minnesota.” The investigative leave led […]

(Beyond Pesticides, June 8, 2007) New research shows that pesticides can reduce the efficiency of nitrogen-fixing plants, impacting soil fertility and ultimately reducing crop yields. The insecticides methyl parathion, DDT and pentachlorophenol were among the chemicals found to inhibit or delay the symbiotic relationship between the legume alfalfa and rhizobia bacteria, which is crucial to nitrogen fixation. Legume crops are often cultivated to help replenish the vital soil nutrient nitrogen (N), but legumes cannot achieve this on their own — Rhizobium bacteria interacts with legumes to convert atmospheric N to nutrient compounds utilizable by plants. Legumes like alfalfa and soybeans are often included in crop rotations due to this beneficial relationship. Nitrogen fixation resulting from the symbiotic relationship between leguminous plants and species of Rhizobium bacteria is an ecological service estimated to be equivalent to $10 billion worth of synthetic N fertilizer annually. Symbiotic nitrogen fixation (SNF) reduces the need for synthetic fertilizers, which cause environmental problems such as impaired water quality. Acknowledging that SNF is both initiated and maintained by chemical signals between the host plant and the beneficial bacteria, the research team postulated that natural and synthetic chemicals could disrupt these signals. The study shows “previously undescribed in […]

(Beyond Pesticides, May 18, 2007) Mosquito season is here in many parts of the country and many communities are reaching for mosquito control sprays as the solution to reducing West Nile Virus infection with little data supporting reduction in risk. Beyond Pesticides urges communities to practice responsible mosquito protection by focusing on reducing breeding grounds and practicing safe personal protection. The first step in avoiding mosquitoes is prevention. Remove any standing water where mosquitos can breed around the home and the schoolyard, such as plant pots, leaky hoses, empty buckets, toys, and old tires. The best way to avoid mosquitoes, especially in the evening when they are most active, is to wear long pants and long sleeves. Burning citronella candles outside also helps repel mosquitoes. Since these two options are not always possible, mosquito sprays can sometimes be a good alternative. Many common mosquito sprays can contain toxic ingredients, however, so it is important to consider all of the option and read labels carefully before buying or spraying the repellents. Some Least-Toxic Mosquito Sprays Include: Oil of Lemon Eucalyptus- CDC recommends lemon eucalyptus oil repellents as a good alternative to DEET. The scented oil of lemon eucalyptus masks both carbon […]

(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, April 23, 2007) Organic produce growers, beef producers, and others testified before Congress this week that industrialized farming has hurt rural communities, the American diet, and family farms and asked that the Farm Bill support the fast growing and successful family businesses that are producing organic foods. The disproportionate subsidies going to conventional agriculture and leaving out organic farmers was brought to light during the first-ever hearing about organics last week before the House Agriculture Committee. Organic farmers are vying this year to gain some federal support as Congress rewrites its five-year farm bill set to expire later this year. Organic growers, now believed to number more than 10,000 are experiencing rapid growth nationwide as interest in healthier food and a healthier environment continues to spread from local farmers’ markets to major supermarkets across the country. Despite this rise is organic markets, growers are not nearly keeping pace with consumer demand for organic products, estimated to be growing by 20 percent a year. Representative Dennis Cardoza, a California Democrat who chairs a new agriculture subcommittee on horticulture and organics, hopes to include organic farmers in the farm bill. Since the Great Depression, congressional farm bills have been dominated […]

(Beyond Pesticides, March 2, 2007) The United States Department of Agriculture’s (USDA) Pesticide Data Program (PDP) recently released its latest annual summary detailing pesticide residues in the U.S. food supply. The data, from 2005, reveals approximately two-thirds of sampled foods contained one or more pesticides at detectable levels. For the 2005 report, PDP sampled fresh and processed fruit and vegetables, soybeans, wheat, milk, heavy cream, pork, bottled water and drinking water. A total of 14,749 samples were tested for various insecticides, herbicides, fungicides and growth regulators. Twelve states reported data to comprise the report: California, Colorado, Florida, Maryland, Michigan, Minnesota, Montana, New York, Ohio, Texas, Washington and Wisconsin. Excluding drinking water, 84 percent of samples originated within the United States. Foods most likely to be consumed by infants and children are analyzed to provide data that is used in the implementation of the Food Quality Protection Act. The data is used in this context to assess dietary exposure to pesticide residues by the Environmental Protection Agency (EPA). Overall results show that, excluding drinking water samples, 36 percent of samples had more than one detectable pesticide, 30 percent had one detectable pesticide, and 34 percent did not have detectable levels of […]
