(Beyond Pesticides, August 31, 2011) Widely grown corn plants that Monsanto Co. genetically modified to thwart a voracious bug are falling prey to that very pest in Iowa cornfields, the first time a major Midwest scourge has developed resistance to a genetically modified crop. The discovery raises concerns that the biotech crops are spawning “superbugs” and calls into question EPA’s allowance of so-called plant incorporated protectants (PIPs). Fields planted in Monsanto’s Bt corn in some areas of the Midwest are showing damage from the corn rootworm””the very species targeted by Monsanto’s engineered trait. Iowa State University entomologist Aaron Gassmann, PhD has discovered that western corn rootworms in four Iowa fields have evolved and can resist the pesticide built into Monsanto’s genetically altered corn seeds. The scientist said the cases were isolated, but he did not know how widespread the problem could become. Farmers in Illinois are also seeing severe rootworm damage in fields planted in Monsanto’s Bt corn. In 2010, Monsanto acknowledged that in industrial-agriculture regions of India, where Monsanto’s Bt cotton is a dominant crop, the cotton-attacking bollworm had developed resistance. “These are isolated cases, and it isn’t clear how widespread the problem will become,” said Dr. Gassmann in […]

(Beyond Pesticides, August 30, 2011) A new study finds that older men living in California’s Central Valley are more likely to develop prostate cancer if they were exposed to certain agricultural pesticides than those who were not exposed. The study examines exposure via drift rather than occupational exposure, although similar results have been noted in farmworker populations. Exposure to methyl bromide or various organochlorine pesticides increased the risk of cancer by about one and a half times. The study, “Prostate cancer and ambient pesticide exposure in agriculturally intensive areas in California,” was published in the June 2011 issue of the American Journal of Epidemiology. The researchers from the University of Southern California’s Keck School of Medicine recruited 173 men between the ages of 60 to 74 from 670 identified by the California Cancer Registry as being diagnosed with prostate cancer between August 2005 and July 2006 in California’s Central Valley. The authors used calendars and questionnaires to determine where they lived and worked between 1974 and 1999, and compared this to historical data of the corresponding area’s agricultural pesticide use from state pesticide use reports and land use records. In comparison with unexposed persons, increased risks of prostate cancer were […]

(Beyond Pesticides, August 29, 2011) The U.S. Environmental Protection Agency (EPA) announced last Thursday that it has entered into an agreement with the California Department of Pesticide Regulation (CDPR) to resolve a civil rights complaint from 1999 which alleged that the department’s renewal of the toxic fumigant methyl bromide in 1999 discriminated against Latino school children whose schools are located near agriculture fields. Per the agreement, CDPR has agreed to expand on-going monitoring of methyl bromide air concentrations by adding a monitor at or near one of the Watsonville, CA area schools named in the original complaint. The purpose of the additional monitor is to confirm that there will be no recurrence of earlier conditions. CDPR will share the monitoring results with EPA and the public and will also increase its community outreach and education efforts to schools that are in high methyl bromide usage areas.EPA says that this is a part of a “backlog” of more than 30 unresolved complaints. The complaint was filed in 1999 under Title VI of the Civil Rights Act of 1964 , which prohibits intentional discrimination and discriminatory effects on the basis of race, color, and national origin by recipients of federal financial assistance.

(Beyond Pesticides, August 24, 2011) Scientists say the fungus that causes apple scab appears to be growing more resistant to pesticides routinely used to control the fungus, worsening the threat of outbreaks in commercial orchards. For decades, manufacturers have come up with replacements for chemical mixtures the fungus outwitted. By using a rotating lineup of fungicides from year to year, farmers usually stayed a step ahead of the scab. But the fungus now appears to be overcoming multiple fungicides at once. In a paper published this month in the journal Plant Disease, researchers described samples collected in Indiana and Michigan that are resisting all four of the most commonly used chemical treatments: dodine, kresoxim-methyl, myclobutanil, and thiophanate-methyl. “We’ve dealt with fungicide resistance over the years, but this time we’re losing three or four different classes of completely unrelated fungicides at the same time,” said Henry Ngugi, PhD, a plant pathologist with Penn State University’s Fruit Research and Extension Center. “We have to literally go back to the drawing board.” Another ominous sign: The fungus apparently hasn’t developed any new weaknesses while evolving to resist the pesticides, unlike what usually happens in nature, the study found. Anecdotal reports from orchard owners […]

(Beyond Pesticides, August 22, 2011) A US Department of Agriculture (USDA) official speaking at an agricultural conference said that the heavy use of Roundup, an herbicide manufactured by Monsanto and used heavily on “Roundup Ready” genetically engineered (GE) crops, appears to be causing harmful changes in soil and potentially hindering yields of crops that farmers are cultivating. Reuters reported that Robert Kremer, PhD, a microbiologist with the USDA’s Agricultural Research Service, told the audience at the August 12, 2011 conference sponsored by the Organization for Competitive Markets that repeated use of the herbicide glyphosate, the key ingredient in Roundup herbicide, impacts the root structure of plants, and 15 years of research indicates that the chemical could be causing fungal root disease. Dr. Kremer first warned us about his research and questioned the government’s response last year. “This could be something quite big. We might be setting up a huge problem,” Dr. Kremer told Reuters last year. “Science is not being considered in policy setting and deregulation. This research is important. We need to be vigilant.” Monsanto created “Roundup Ready” crops to withstand its Roundup herbicide (with the active ingredient glyphosate). Growing previous Roundup Ready crops such as soy, cotton, and […]

(Beyond Pesticides, August 18, 2011) A new report by the Australian government finds that agricultural pesticides are severely damaging the Great Barrier Reef; despite this fact, sugarcane growers have been allowed a six week extension to continue to use the weed killer diuron, which was intially set to be suspended for use on August 13. The Reef Water Quality Protection Plan First Report Card estimates that 28,000 kilograms (or approximately 61,730 pounds) of pesticides enter the reef, which is the world’s largest structure made up of living organisms and a World Heritage natural wonder. The findings in the report corroborate previous research on the health of the Great Barrier Reef. The sugarcane industry claims that the research is based on old data and that there have been significant changes in practices, including cutting back on the use of pesticides. Though the Australian government acknowledges these changes, those improvements have been undermined by Cyclone Yasi. The heavy flooding from Yasi, which ripped through the region earlier this year, likely flushed pollutants out into the reef. According to the industry, the suspension of the use of diuron would drive up the costs for sugarcane growers because there is no viable alternative to […]

(Beyond Pesticides, August 16, 2011) A lawsuit filed in federal court against the U.S. Fish and Wildlife Service (FWS) seeks to end cultivation of genetically engineered (GE) crops on twenty-five national wildlife refuges across the U.S. Southeast. The suit is the latest step in a campaign to banish GE crops from all refuges. Filed in the U.S. District Court for the District of Columbia on August 12, 2011 by Public Employees for Environmental Responsibility (PEER), the Center for Food Safety (CFS), and Beyond Pesticides, the federal suit charges that FWS unlawfully entered into cooperative farming agreements and approved planting of GE crops in eight states without the environmental review required by the National Environmental Policy Act (NEPA) and in violation of FWS policy. This is the third in a series of lawsuits filed by CFS and PEER challenging FWS’s practice of permitting GE crops on wildlife refuges. In 2009 and 2010, the groups successfully challenged approval of GE plantings on two wildlife refuges in Delaware — Prime Hook National Wildlife Refuge and Bombay Hook National Wildlife Refuge — which forced FWS to end GE planting in the entire 12-state Northeastern region. National wildlife refuges have allowed farming for decades despite […]

(Beyond Pesticides, August 15, 2011) Poultry farms that have adopted organic practices and cease using antibiotics have significantly lower levels of drug-resistant enterococci bacteria that can potentially spread to humans, according to a new study published August 10, 2011 in the online edition of Environmental Health Perspectives. The study, led by researchers at the University of Maryland’s School of Public Health, suggests that organic conversion of U.S. poultry farms can result in immediate and significant reductions in antibiotic resistance for some bacteria. The non-therapeutic use of antibiotics in livestock production accounts for nearly 80% of all antibiotics used in the United States. Typically, low levels of antibiotics are administered to animals through feed and water to prevent disease and promote growth. This is generally done to compensate for overcrowded and unsanitary living conditions, as is common in concentrated animal feeding operations (CAFOs), and to fatten livestock to get them to market sooner. Antibiotic use is prohibited in the production of all animal products labeled organic. “We initially thought we would see some differences in on-farm levels of antibiotic-resistant enterococci when poultry farms transitioned to organic practices. But we were surprised to see that the differences were so significant across several […]

(Beyond Pesticides, August 11, 2011) A combination of eleven different kinds of commonly used pyrethroids were tested on mice in a new study which found that, at real-world exposure levels, the insecticides can produce heightened toxicity that is equal to the sum of each insecticide’s individual effect. The mixture of similar-acting insecticides works by over-stimulating electronic channels in the mouse’s brain cells and eventually causing death. This study adds to the growing body of research on the toxicity of pesticide combinations in nature and showcases the need for policy change because the current risk assessment approach to regulating pesticides fails to look at chemical mixtures and synergistic effects. The U.S. Environmental Protection Agency (EPA) currently regulates on a chemical-by-chemical basis, but as this study demonstrates, interacting chemicals can have synergistic effects at very low levels, where a “chemical cocktail” of multiple interacting chemicals combine to have greater effects than expected. Pesticides can also have a cumulative “toxic loading” effect both in the immediate and long term. Researchers exposed mice brain cells to eleven different food-use pyrethroid insecticides either singly or in a mixture in the study entitled ”Additivity of pyrethroid actions on sodium influx in cerebrocortical neurons in primary culture.” […]

(Beyond Pesticides, August 10, 2011) A citizen advisory council in Boulder County, Colorado is preparing to decide on whether or not to recommend that genetically modified organisms (GMOs) be banned from county lands. The County’s Croplands Policy Advisory Group will meet on Wednesday, August 10 (agenda packet here) to decide if they want farmers who plant their crops on county land to be able to be able to grow crops that have been genetically modified. With organic farmers around the country worried about potential contamination of their crops with GMO pollen following a number of recent regulatory decisions, the citizen council model may represent a good way for communities to come together and find a solution. Currently, many farmers grow on land owned by the county, and some want to plant GMOs to stay competitive with other farmers around the country. However, some citizens of the county are concerned about the widespread use of GMOs and the increased reliance on agricultural chemicals that usually accompanies them. Organic farmers in the area are also very worried. Recent decisions by the U.S. Department of Agriculture have led to the deregulation of several genetically engineered varieties of common crops, including alfalfa and sugar […]

(Beyond Pesticides, August, 8, 2011) In a move that highlights serious concerns regarding the pesticide registration process, DuPont has announced that it plans to issue a total recall of its new herbicide, Imprelis, following widespread evidence and complaints that the product has caused the deaths of trees around the country. After originally giving conditional approval to the new pesticide, the U.S. Environmental Protection Agency (EPA) has now stated that it is preparing to issue a “Stop Sale” order to halt any further use of the product. According to a letter posted on DuPont’s website Imprelis-Facts.com, the company is implementing a “voluntary suspension” of Imprelis sales. It intends to ask distributors to collect all Imprelis containers, even those partially used, that they have sold and return them to the company for a refund. Earlier this year, in what some said was one of the biggest disasters of its kind since the emerald ash borer killed millions of trees, Imprelis was linked to white pine and Norway spruce trees turning brown or dying all across the country. Tree damage was reported throughout the Midwest, in East Coast states and as far south as Georgia. Many landscapers in Michigan and elsewhere switched to […]

(Beyond Pesticides, August 5, 2011) The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice (DOJ) announced last week that Dow Chemical Company (Dow) has agreed to pay a $2.5 million civil penalty to settle violations of the Clean Air Act, Clean Water Act and the Resource Conservation and Recovery Act (RCRA) at its chemical manufacturing and research complex in Midland, Michigan. In addition to paying a penalty, Dow will implement a comprehensive program to reduce emissions of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from leaking equipment, such as valves and pumps. These emissions —known as fugitive emissions because they are not discharged from a stack, but rather leak directly from equipment— are generally controlled through work practices, such as monitoring for and repairing leaks. The settlement requires Dow to implement enhanced work practices, including more frequent leak monitoring, better repair practices, and innovative new work practices designed to prevent leaks. In addition, the enhanced program requires Dow to replace valves with new “low emissions” valves or valve packing material, designed to significantly reduce the likelihood of future leaks of VOCs and HAPs. Past waste disposal practices, fugitive emissions, and incineration at the Midland plant […]

(Beyond Pesticides, August 4, 2011) At least 21 different species of weeds are found to be resistant to the herbicide glyphosate, commonly sold as Roundup and used across thousands of acres of “RoundUp Ready” genetically engineered (GE) crops, according to a series of studies in the current issue of Weed Science. Palmer amaranth, one of the weeds discussed in the journal, can reduce yields of cotton by more than 50 percent if there is a density of at least 10 of these weeds per row. Fifty-two counties in the state of Georgia had infestations of glyphosate-resistant Palmer amaranth last year. Studies confirm that the weed, which also competes with soybean, corn, grain sorghum and peanut crops, is also resistant to the herbicide phrithiobac in addition to glyphosate. Over-application and over-reliance by farmers on glyphosate to solve all of their weed problems has led to the proliferation of so-called “super weeds,” which have evolved to survive the treatments through repeated exposure. The most common species which have evolved these traits include pigweed (palmer amaranth), mare’s tail, and ryegrass. The spread of resistance is what has led farmers to increasingly rely on more toxic alternative mixtures, including weed killers like atrazine. There […]

(Beyond Pesticides, August 2, 2011) Under pressure from lab results showing arsenic in apple juice, the U.S. Food and Drug Administration (FDA) and New York state officials inspected a Williamson, NY Mott’s apple products plant for the toxic metal on July 26, 2011. While the lab tests commissioned by the Rochester-based Empire State Consumer Project examined several brands of apple juice and apple sauce, Mott’s Apple Juice stood out, with one sample registering 55 parts per billion of arsenic, five times higher than the Environmental Protection Agency’s (EPA) legal limit (tolerance level) for drinking water. While no longer used in U.S. orchards, arsenic-based pesticides are still used on food crops in some countries, including China. “This is not the first time high levels of arsenic have been found in apple juice,” said Judy Braiman, executive director of the Empire State Consumer Project. “It is past time for the FDA to set a limit on a toxic substance like arsenic with long term health effects in the juice that kids drink.” Two-thirds of apple juice that Americans consume ””more than 400 million gallons annually”” comes from China. The Empire State Consumer Project and Food & Water Watch sent a letter to […]

(Beyond Pesticides, August 1, 2011) After sighting three Japanese beetles in the vicinity of Greenback Lane and Fair Oaks Boulevard in Sacramento County, California, state officials are scheduled to spray pesticides linked to cancer, reproductive and neurological effects. On August 2, the California Department of Food and Agriculture (CDFA) is scheduled to begin ground applications of carbaryl on fruit-bearing trees, and cyfluthrin on non-fruit-bearing trees and landscape plants in attempts to stave of attacks from the voracious Japanese beetle. Japanese beetles, a threat to turf grass as well as ornamental plants such as roses and cut flowers, have been detected in the Fair Oaks area, state officials said, but the ”˜infestation’ appears to be localized. To keep the ”˜infestation’ from spreading countywide, Juli Jensen, Acting Agricultural Commissioner, is urging residents in the area not to move plants or plant parts. The initial treatments will be directed at adult beetles and begins August 2 with applications of carbaryl on fruit-bearing trees, and cyfluthrin on non-fruit-bearing trees and landscape plants. Two weeks later, a second treatment will be applied and augmented by a granular imidacloprid to target grubs. The applications, to occur on approximately 100 properties, will be carried out by the […]

(Beyond Pesticides, July 26, 2011) On July 25, 2011, in the case of Oluf Johnson v. Paynesville Farmers Union Cooperative Oil Company, Judge Ross of the Minnesota Court of Appeals ruled that pesticides drifting from one farm to another may constitute trespass. Organic farmers Oluf and Debra Johnson filed a civil suit alleging that the oil company sprayed a pesticide that drifted from targeted fields onto theirs, and that this prevented them from selling their crops as organic. Previously, a district court dismissed the Johnsons’ trespass claims. The victory is important for organic growers who are frequently under threat of pesticide drift from neighboring properties. Under the federal organic standards authorized by the Organic Foods Production Act (OFPA), produce may not be labeled organic if it is contaminated with pesticide residues, as a result of off-site use, o greater than five percent of the allowable pesticide tolerance levels. Pesticide tolerances are the pesticide residue limits used in the U.S. or by countries imporing to the U.S., which are set by the federal government under the Food Quality Protection Act (FQPA). Because we live in a polluted world where pesticide residues are present, often at low levels, nearly everywhere. A very […]

(Beyond Pesticides, July 25, 2011) Exposure to certain pesticides and polycyclic aromatic hydrocarbons (PAHs) in the womb has been linked to neural tube defects, which lead to conditions such as spina bifida, according to researchers at Peking University in China. The study finds elevated levels of the organochlorine pesticides DDT, alpha-hexachlorocyclohexane (a lindane contaminant) and endosulfan, as well as PAHs in the placentas of women who had babies or aborted fetuses with such birth defects. The study, “Association of selected persistent organic pollutants in the placenta with the risk of neural tube defects,” was published July 8, 2011 in the online edition of the Proceedings of the National Academy of Sciences. While most organochlorine pesticides are banned or restricted, they still continue to cause problems decades after their widespread use has ended. This study reinforces the need for a more precautionary approach to regulating pesticides and industrial chemicals. Once released into the environment, many chemicals can affect health for generations, either through persistence or genetic means. PAHs are a group of over 100 different chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances like tobacco or charbroiled meat. PAHs are usually […]

(Beyond Pesticides, July 22, 2011) Parallel bills have been introduced in the U.S. Senate and U.S. House of Representatives designed to increase federal research on endocrine disrupting chemicals and ensure public safety by restricting or eliminating chemicals found to present unacceptable risks to public health. S 1361, introduced by Senator John Kerry (D-MA), and HR 2521, introduced by Rep. Jim Moran (D-VA), are both titled the Endocrine-Disrupting Chemicals Exposure Elimination Act. The bills would establish a scientific panel at the National Institute of Environmental Health Sciences (NIEHS) to evaluate up to ten chemicals per year that potentially affect the endocrine system and would create a trigger to ban those found most harmful to public health. The bills would create a more updated scientific evaluation process than any that currently exists in the federal government for reviewing potential endocrine disruptors and would have a strong regulatory mandate to ban or restrict chemicals that are found to present serious health risks. The specific process outlined directs the National Toxicology Program at NIEHS to evaluate each chemical according to (i) the amount of evidence that it is an endocrine disruptor, (ii) the “level of concern” that it may disrupt hormones, and (iii) the […]

(Beyond Pesticides, July 20, 2011) With flavors like “tangelo orange twist,” and “sugar lemon fizz,” popular body care chain, Bath and Body Works, has marketed an entire line of antibacterial body care products to teens and young adults. Unfortunately, these products contain the toxic hormone disruptor and water contaminant, triclosan, which could be hazardous to teenagers whose bodies are still developing. Join Beyond Pesticides, Center for Environmental Health, and The Campaign for Safe Cosmetics in asking Bath and Body Works to stop selling triclosan products that claim to “Spread Love, Not Germs.” The Bath and Body Works antibacterial line, which includes products with names like “Tangelo Orange Twist” and “Sugar Lemon Fizz,” is marketed to teenagers using the slogan “spread love, not germs.” Although not listed on their website, this antibacterial line and others sold by the company contain triclosan as their main germ fighting ingredient. Beyond Pesticides in 2004 began voicing concern about the dangers of triclosan and in 2009 and 2010, submitted petitions to the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA), calling for the removal of triclosan from consumer products. Since then many major companies are quietly and quickly removing triclosan […]

(Beyond Pesticides, July 19, 2011) According to a U.S. Department of Agriculture (USDA) study published in the Journal of Environmental Quality, the volatilization of atrazine and metolachlor, two herbicides known to contaminate surface and ground water, consistently results in herbicide movement off the target site that exceeds nontarget field runoff, varying widely depending upon weather conditions. Linked to endocrine disruption, cancer, developmental effects, and more, increased levels of these hazardous pesticides in the air is cause for concern. When averaged over the two herbicides, loss by volatilization is about 25 times larger than movement from surface runoff, despite low vapor pressures. Agricultural Research Service (ARS) soil scientist Timothy Gish, PhD and ARS micrometeorologist John Prueger, PhD led the investigation, which looks at the field dynamics of these two herbicides commonly used in corn production. Prior to this field study, many experts believed that volatilization was not a contributing factor to water contamination because atrazine and metolachlor had a low vapor pressure. However, the monitoring of both herbicide volatilization and surface runoff at the field-scale over multiple years had never been done. So the team set up a 10-year study in an experimental field in Beltsville that is equipped with remote […]

(Beyond Pesticides, July 15, 2011) A study conducted by researchers at Michigan State University and published in the Proceedings of the National Academy of Sciences has linked the growth of industrial farming systems to increased pest pressure and higher pesticide use, highlighting the importance of biodiversity in agriculture. The researchers found that “landscape simplification” in the form of conversion of natural areas to intensive monocultural crop production results in increased pest populations through the removal of natural habitat for pest predators. This in turn leads to higher rates of pesticide application by farmers in response to the increased pest pressure. As wild areas providing natural habitat to a range of wildlife and beneficial insects are destroyed and converted to conventional crop production, pest populations in the area will be robbed of their natural predators. This leads to pest population booms and to a corresponding increase in pesticides in an attempt to control them. Monocultural crop production —growing a single crop on hundreds and often thousands of acres— presents a uniquely perfect breeding ground for pests as it provides acres upon acres of food and habitat with no natural checks or barriers. The study lays out the problems in this way: […]

(Beyond Pesticides, July 13, 2011) Millions of dollars’ worth of Norway spruce and white pine trees are mysteriously turning brown and dying this summer, and the chief suspect is a new lawn chemical. The product, Imprelis, a new herbicide manufactured by DuPont, is suspected by State officials and lawn care professionals who say they think Imprelis may be attacking pines and spruces. Once again, this new incident exposes the deficiencies in the registration process for new pesticides put onto the market without a full data set. In what some say could be one of the biggest disasters of its kind since the emerald ash borer killed millions of trees, white pine and Norway spruce trees are turning brown or dying all around the country. Tree damage has been reported throughout the Midwest, in East Coast states and as far south as Georgia. Many landscapers in Michigan and elsewhere switched to Imprelis (See the MSDS here) this year to control weeds such as dandelions because it was touted as “safer” by DuPont for the environment than predecessors such as 2, 4-D. So many trees have died -from the East Coast west to Iowa – that the damage is projected to be […]
