Genetically Engineered Crops to Boost Use of 2, 4-D and Dicamba

(Beyond Pesticides, November 7) Once heralded as a breakthrough for reducing the rates and toxicity of the pesticides applied by farmers, genetically engineered (GE) crops are perversely leading to renewed dependency on the very herbicides they were claimed to make obsolete. Growing recognition that pervasive planting of “Round-Up Ready” corn, soybeans and cotton is accelerating weed resistance is prompting GE seed companies to rush to market ‘stacked’ varieties that are resistant to additional herbicides, including 2, 4-D and dicamba. Farmers planting the stacked varieties will be spraying these older herbicides in addition to glyphosate, which most commodity crops have already been engineered to tolerate. Professor David A. Mortensen of Pennsylvania State University has estimated that adoption of Round-Up Ready and 2, 4-D or dicamba resistant stacked varieties in soybeans could result in a 70% increase in herbicide use in a relatively short time. The St. Louis Pots-Dispatch reported on progress that multinational chemical corporations Dow AgroSciences, BASF, and Monsanto are making to bring multi-herbicide resistant varieties to market. Under separate arrangements with each company, Monsanto adds glyphosate resistance to seeds that are simultaneously engineered to resist other herbicides. In October, Dow AgroSciences obtained a global patent on its Enlist Duo […]

Court Upholds Protection for Salmon Protections

(Beyond Pesticides, November 2, 2011) On Monday, a federal judge rejected a lawsuit brought by Dow AgroSciences challenging pesticide application restrictions to protect salmon and upheld the measures recommended by the National Marine Fisheries Service (NMFS) to protect endangered salmon and steelhead from three highly toxic pesticides: chlorpyrifos, diazinon, and malathion. The restrictions, recommended by NMFS’s Biological Opinion in 2008, ban the ground spraying of the three commonly used organophosphate agricultural insecticides within 500 feet of any salmon-bearing waterway, and aerial spraying within 1,000 feet. NMFS has issued four Biological Opinions, the latest on June 2011, which call for several limitations on aerial spraying and ground application of the pesticides near salmon waters, as well as buffer zones around salmon waters and ditches that drain to salmon habitat, among others. EPA was court ordered to consult with NMFS to identify measures needed to protect salmon and steelhead from the pesticides as a result of a 2002 and 2007 lawsuit. Pesticide manufacturers have been willfully ignoring and challenging NMFS’s findings. Dow AgroSciences alleged that NMFS used bad data and modeling and that the proposed buffers are far too large. Earthjustice, representing Northwest Center for Alternatives to Pesticides (NCAP), Pacific Coast Federation […]

NJ School Pesticide Exposure Incident Reinforces Need for Policy

(Beyond Pesticides, October 31, 2011) The Borough Council of Oradell, NJ has pledged to review the use of pesticides on public grounds following an incident in which children may have been allowed to prematurely re-enter an herbicide-treated soccer field. This incident recalls the recently reported exposure and poisoning that occurred in Ohio a few weeks ago, and echoes the need for a comprehensive national policy to protect children from harmful and unnecessary exposure to toxic chemicals. The on-line edition of The Record reported on October 25 that the Council acted in response to a complaint filed as a result of an herbicide application to Memorial Field on October 6. The complaint stated that despite numerous posted signs warning children should not to enter the treated area for 72 hours, two youth soccer teams were playing on the field six hours after the application. The complaint further stated that the town’s Department of Public Works had removed all but one of the warning signs by the next day when another soccer game was played. The Record also reported that the field is open and accessible to members of the general public. Children are especially sensitive and vulnerable to pesticides because of […]

Students Poisoned by Pesticides Sprayed on Playing Field Outside of Classroom

(Beyond Pesticides, October 27, 2011) Forty-seven students from Edgewood Middle School in St. Clair Township, Ohio, reportedly fell ill after the school’s hired pest control company sprayed the herbicide Momentum, which contains the toxic ingredients 2,4-D, triclopyr and clopyralid, on nearby playing fields to treat for clover and other weeds. The incident and others like it demonstrate the need for a comprehensive national policy to protect children from harmful and unnecessary exposure to toxic chemicals. Six students were taken to nearby hospitals and twenty-one students total were treated for symptoms, including headaches, breathing difficulties, nausea and dizziness. Children are especially sensitive and vulnerable to pesticides because of their rapid development and behavior patterns. Adverse health effects, such as nausea, dizziness, respiratory problems, headaches, rashes, and mental disorientation, may appear even if a pesticide is applied according to label directions, which may have been the case in this situation. Pesticide exposure can have long-term adverse effects, including damage to a child’s neurological, respiratory, immune, and endocrine system and increased asthma symptoms. Studies show that children living in households where pesticides are used suffer elevated rates of leukemia, brain cancer, and soft tissue sarcoma.

Group Files Lawsuit for Failure to Protect Red-Legged Frogs

(Beyond Pesticides, October 20, 2011) The Center for Biological Diversity filed a lawsuit yesterday against the Environmental Protection Agency (EPA) and U.S. Fish and Wildlife Service (FWS) for failing to evaluate and act on threats to the threatened California red-legged frog posed by more than 60 toxic pesticides used in and near its habitats. The Center had announced its intent to sue the two agencies back in December 2010. A 2006 legal settlement secured by the Center requires EPA to assess the impacts of harmful pesticides on red-legged frogs and formally consult with the Fish and Wildlife Service to address those impacts. EPA determined that widespread use of more than 60 pesticides is likely harming red-legged frogs, but since the agency and the Fish and Wildlife Service have failed to complete the required evaluations, no permanent protections for frogs have been put in place. “Federal agencies acknowledge that scores of pesticides may harm California’s rare red-legged frogs, but for years now they’ve neglected to complete biological evaluations of the effects of these chemicals,” said Jeff Miller, a conservation advocate with the Center. “California’s imperiled frogs are suffering as a result.” “Biological opinions,” the evaluations required by the Endangered Species Act, […]

Tell USDA To Deny Deregulation of GE “Roundup Ready” Sugar Beets

(Beyond Pesticides, October 18, 2011) The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) recently announced the availability of a draft environmental impact statement (EIS) that evaluates the potential environmental effects of deregulating (commercializing) sugar beets genetically engineered (GE) to be resistant to the herbicide glyphosate, commonly referred to as Roundup Ready (RR) sugar beets. APHIS considered three alternatives in the draft EIS: deny the petition seeking a determination of nonregulated status (prohibit commercial planting), make a determination of nonregulated status (allow commercial planting), or extend the partial deregulation of RR sugar beets for the root crop, with mandatory conditions and restrictions. Comments will be accepted until December 13, 2011. APHIS originally deregulated RR sugar beets in 2005. A coalition of environmental groups and organic seed companies, led by the Center for Food Safety, challenged the USDA approval in 2008. It argued that GE sugar beets would contaminate organic and non-GE farmers of related crops, such as table beets and chard, as well as increase pesticide impacts on the environment and worsen the current Roundup-resistant “superweeds” epidemic in U.S. agriculture. In September 2009, Judge Jeffrey S. White in the federal district court in San Francisco agreed, […]

Residents Battle with City Park District To Prevent Toxic Pesticide Use

(Beyond Pesticides, October 17, 2011) Backlash from local residents in an Illinois city has pressured park officials to keep chemical pesticides off of athletic fields, successfully stopping a planned chemical treatment in November and postponing the city’s decision to spray until they hear more from concerned residents and turf experts. For four years, the Park Board of Highland Park, IL has managed its playing fields without the use of chemical pesticides and herbicides. Back in August, however, the Park Board decided to allow its groundskeepers to apply herbicides in order to control dandelions, clover, and other unwanted plants at three local parks. Over 70 residents sent emails to the Park Board and administration, and an online petition has collected 683 signatures opposed to the city park commissioners’ decision to spray the chemical pesticides. In response to public concern, Bruce Branham, PhD, a Professor of the Department of Crop Sciences at the University of Illinois wrote a statement to the park officials in favor of spraying, citing the U.S. Environmental Protection Agency (EPA) pesticide registration process as establishing the safety of the pesticides being proposed for use by the Park Board. Beyond Pesticides responded with a letter

New Research Links Pesticides to Cardiovascular Disease

(Beyond Pesticides, October 14, 2011) Researchers at Uppsala University in Sweden have found that environmental toxicants such as dioxins, PCBs, and pesticides can pose a risk for cardiovascular disease. The results of the study, entitled “Circulating Levels of Persistent Organic Pollutants (POPs) and Carotid Atherosclerosis in the Elderly,” show a link between exposure to persistent organic pollutants (POPs), including several organochlorine pesticides, and the development of atherosclerosis, which can lead to heart disease. The study will be published in the journal Environmental Health Perspectives, and a version of it is available online ahead of print. Cardiovascular diseases, including heart attacks and strokes, are the most common cause of death in industrialized countries, and the most important underlying cause of these diseases is atherosclerosis. Unbalanced blood fats, diabetes, smoking, and high blood pressure are traditionally recognized risk factors for atherosclerosis. Previous studies have also reported possible links between cardiovascular disease and high levels of persistent (long-lived and hard-to-degrade) organic environmental toxicants, such as dioxins, polychlorinated biphenyls (PCBs), and pesticides. These compounds are fat-soluble and can therefore accumulate in vessel walls. However, no earlier studies have investigated possible links between exposure to these compounds and atherosclerosis. Of the POPs that were screened […]

Industry Study Touts ‘Safety’ of Triclosan Soaps, Dismissing Independent Adverse Effects Data

(Beyond Pesticides, October 12, 2011) A new industry-funded study that claims to “Reaffirm Safe Use of Triclosan, Triclocarban in Antibacterial Soaps and Washes,” concludes that triclosan and triclocarban soaps do not facilitate antibiotic resistance and antibiotic cross-resistance. The study, sponsored by the American Cleaning Institute and the Personal Care Products Council, long supporters of the antibacterial pesticide triclosan, dismisses previous independent data that has identified triclosan as a promoter of antibacterial resistance and calls for precautionary measures against the unnecessary but widespread use of antibacterial agents. The study, “Investigation of Antibiotic and Antibacterial Susceptibility and Resistance In Staphylococcus From The Skin Of Users and Nonusers Of Antibacterial Wash Products In Home Environments,” found that there was no statistically significant difference in antibiotic resistance in the bacteria, Staphylococcus aureus, exposed to triclosan and triclocarban soaps compared with those not exposed. The study collected swab samples from the forearms of participants that used triclosan, triclocarban, and a control group that used neither. The study’s conclusions are not surprising since this industry has been a vocal and active promoter of the antibacterial products they manufacture and represent. Beyond Pesticides has previously responded to the American Cleaning Institute’s (formerly the Soap and Detergent Association) […]

Mosquito Pesticide Suspected in Lobster Deaths

(Beyond Pesticides, October 7, 2011) Commercial lobster fishers operating in Long Island Sound off the coast of Connecticut have begun to suspect that the mosquito killing chemical methoprene, sprayed by neighboring New York State as part of its West Nile virus (WNv) control program, is contributing to widespread deaths of lobsters in the sound. Believing that a large amount of the chemical flowed into the sound in late summer due to heavy rains from Hurricane Irene, the lobster fishers are asking New York to follow Connecticut’s example and switch its WNv control method to the less toxic bacillus thuringiensis. Late summer declines in the sound’s lobster population have been alarmingly common throughout much of the last decade, devastating fishers and the local economy that depends on them. A number of factors have been blamed, but the lobstering community has increasingly been pointing to mosquito pesticides for several reasons. Methoprene has a tendency to sink to the bottom of the ocean water, where lobsters live and feed. Additionally, lobsters are a distant cousin of mosquitoes, and the methoprene acts on them in much the same way that it does the insects. Finally, the western part of the sound was the hardest […]

Bayer To Withdraw Most Acutely Toxic Pesticides, Leave Other Hazardous Products on Market

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

Triclosan Among Chemicals Detected in Narragansett Bay

(Beyond Pesticides, 9-30-11) Researchers from the University of Rhode Island (URI) have detected the antimicrobial triclosan and other toxic chemicals in the waters of Narragansett Bay off the coast of Rhode Island. The chemicals are a group of hazardous compounds that are common in industrial processes and personal care products but are not typically monitored by the U.S. Environmental Protection Agency (EPA). Rainer Lohmann, Ph.D., associate professor of chemical oceanography, and graduate student Victoria Sacks, with the help of 40 volunteers, tested for the presence of the chemicals in 27 locations throughout the bay. The compounds were found at every site. “Being exposed to these compounds is the hidden cost of our lifestyle,” said Dr. Lohmann. “It’s frustrating that as we ban the use of some chemical compounds, industry is adding new ones that we don’t know are any better.” Although the chemicals were detected at very low levels, research has shown that many chemical compounds can still be quite toxic, even at low doses. Additionally, since triclosan is an antimicrobial agent, low concentrations provide the perfect environment in which to breed and select for bacteria that resist the effects of the chemical. “By themselves, none of these results makes […]

Centers for Disease Control Reports Illness and Death Linked to Bed Bug Pesticides

(Beyond Pesticides, September 26, 2011) On September 23, 2011, the Centers for Disease Control and Prevention (CDC) published a study in its Morbidity and Mortality Weekly Report linking pesticides sprayed in attempts to control bed bugs to poisoning incidents and death. Because bed bugs do not transmit disease and can be controlled without pesticides, this risk is completely unnecessary. The study, “Acute Illnesses Associated with Insecticides Used to Control Bed Bugs,” utilized data from California, Florida, Michigan, North Carolina, New York, Texas, and Washington. In those seven states, over 100 poisonings, including one fatality, were associated with bed bug-related insecticide use. The CDC researchers used data from states participating in the Sentinel Event Notification System for Occupational Risks (SENSOR)-Pesticides program and the New York City Department of Health and Mental Hygiene (NYC DOHMH). The authors defined “acute illness” associated with an insecticide used to control bed bugs as two or more acute adverse health effects resulting from exposure to an insecticide used for bed bug control. The study reports: A total of 111 illnesses associated with bed bug–related insecticide use were identified; although 90 (81%) were low severity, one fatality occurred. Pyrethroids, pyrethrins, or both were implicated in 99 (89%) […]

Distribution and Sale of Illegal Pesticides Busted

(Beyond Pesticides, September 21, 2011) An unregistered pesticide product, which was smuggled into the U.S. from overseas and contained an ingredient at a concentration of nearly 61 times greater than allowed by federal regulations, was one of 6,000 rat and cockroach poison products seized from shops and street vendors in and around New York’s Chinatown. The pesticides are particularly dangerous because their packaging and appearance could lead them to be mistaken for cookies or cough medicine. The U.S. Environmental Protection Agency (EPA), with several other federal and state agencies, including the New York State Department of Environmental Conservation (DEC), the New York Office of U.S. Immigrations and Customs Enforcement’s (ICE) Homeland Security Investigations (HIS), and the New York Office of the United States Postal Inspection Service (USPIS), on Monday announced federal criminal charges against two defendants, and state criminal charges against 10 defendants, for their respective roles in the illegal distribution and sale of unregistered and misbranded pesticides that were sold out of multiple locations in Manhattan. All pesticides pose unique risks to users and the environment at large since they are designed to kill living organisms; many have been linked to several chronic diseases including cancer.

Army-Funded Study Links Gulf War Illness to Pesticides and More

(Beyond Pesticides, September 20, 2011) A study supported by the U.S. Army Medical Research and Materiel Command links pesticide exposure and other factors to Gulf War illness (also referred to as Gulf War Syndrome), an illness characterized by a wide range of acute and chronic symptoms experienced by veterans and civilians after the 1991 Gulf War. The study, “Complex Factors in the Etiology of Gulf War Illness: Wartime Exposures and Risk Factors in Veteran Subgroups,” is published in the September 19, 2011 online edition of Environmental Health Perspectives. The researchers designed the study to compare the characteristics of deployment and the risk factors experienced by veterans participating in various theaters of the Gulf War. Among personnel who were in Iraq or Kuwait, where all battles took place, four exposures were independently associated with GWI: taking PB pills, being within one mile of an exploding SCUD missile, using pesticides on the skin, and exposure to smoke from oil well fires. For veterans who remained in support areas, GWI was significantly associated only with personal pesticide use, with increased prevalence (OR=12.7, CI=2.6-61.5) in the relatively small subgroup who wore pesticide-treated uniforms, nearly all of whom also used skin pesticides. Among 64 pesticide […]

EPA Publishes Petition to Ban Atrazine in the U.S.

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

Use of Soil Fumigant Still High Despite Ban

(Beyond Pesticides, September 12, 2011) While the fight continues over the use of toxic methyl iodide in California, new research is showing that the banned chemical methyl bromide, which methyl iodide was intended to replace, is continuing to be used in alarming amounts across the state due to a sizeable loophole in the regulations. While some may argue that this is simply a consequence of the controversy surrrounding methyl iodide, those concerned with human health and the environment point out that it is irresponsible and counterproductive to replace a devastating environmental contaminant with a highly toxic human carcinogen, especially when there are more responsible alternatives to both which can be employed. Most methyl bromide is used to fumigate, or sterilize, agricultural soils, especially those growing strawberries, though it is used for other crops as well. It is also used in high amounts as a structural fumigant to eradicate indoor pests. The most common applications of this kind are for residential termite treatments and for insects in food storage facilities. An investigation by New America Media has found that use of methyl bromide in California in 2009 was still at nearly 50% of levels from ten years prior, before the supposed […]

Dow Seeks Approval of New Soybean Resistant to Multiple Herbicides

(Beyond Pesticides, September 9, 2011) Despite rising concerns over the side effects of herbicide tolerant, genetically engineered (GE) crops, Dow AgroSciences has recently asked for approval of a new GE soybean variety that will be the first ever to be simultaneously resistant to three different pesticides. The soybean variety, which the company is calling “Enlist,” is designed to compete with Monsanto’s line of “Roundup Ready” crops, which are engineered to be resistant to the company’s glyphosate formulation. The Enlist soybean will be resistant to glyphosate as well as glufosinate and 2,4-D. Antonio Galindez, CEO of Dow AgroSciences, told Reuters that the Enlist system is the company’s “most important project ever.” This is likely due to the company’s ambitious target of taking over Monsanto’s dominance of the GE market in American agriculture. Herbicide tolerant (HT) Roundup Ready crop varieties have become nearly ubiquitous in the corn, cotton, and soybean seed markets. Dow will market the product as a replacement for Roundup Ready soybeans. If farmers are finding that weeds in their fields are not responding to applications of Roundup, Dow will argue, then planting Enlist soybeans will allow them to spray a combination of chemicals in order to eradicate the resistant […]

New Issues Arise Over Methyl Iodide Use

(Beyond Pesticides, September 7, 2011) California’s approval of the dangerous and controversial agricultural chemical, methyl iodide, suffered serious questions with the release of new documents showing the fumigant’s registration process was flawed. The documents, which were made public as part of a lawsuit challenging the state’s approval of the chemical, show the state’s Department of Pesticide Regulation (DPR) cut and pasted calculations from different risk assessments in order to come up with a less stringent set of restrictions on the chemical’s use. Earlier this year, several environmental groups sued the State of California for approving the agricultural use of methyl iodide. Methyl iodide is known to cause miscarriages, thyroid dysfunction, and cancer, and is applied to crops like strawberries and peppers. It was approved by California state pesticide regulators in December as an alternative to methyl bromide, an ozone-depleting chemical being phased out under international treaty. Environmental advocacy groups and other opponents of methyl iodide use in the state have released documents detailing dissension in the ranks of DPR over the risk assessment of methyl iodide and its subsequent approval. Earthjustice, a nonprofit environmental law group, sued DPR in an attempt to reverse the state’s approval of the chemical. The […]

Low Doses of Pesticides Put Honey Bees at Risk

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

Widespread Glyphosate Contamination Detected in Air and Waterways

(Beyond Pesticides, September 2, 2011) The widely used herbicide glyphosate, the active ingredient in Roundup, has been detected in significant levels in rain and rivers in agricultural areas across the Mississippi River watershed, according to two new studies released this month by the U.S. Geological Survey (USGS). The studies’ results raise serious concerns about public exposure and potential environmental damages. Detailed results are available in “Occurrence and fate of the herbicide glyphosate and its degradate aminomethylphosphonic acid in the atmosphere,” published in Environmental Toxicology and Chemistry and in “Fate and transport of glyphosate and aminomethylphosphonic acid in surface waters of agricultural basins,” published online in Pest Management Science. Glyphosate is used in almost all agricultural and urban areas of the United States. The greatest glyphosate use is in the Mississippi River basin, where most applications are for weed control on genetically-modified corn, soybeans and cotton. Overall, agricultural use of glyphosate has increased from less than 11,000 tons in 1992 to more than 88,000 tons in 2007. The two studies conducted by USGS examine glyphosate content in air and water samples in the states of Iowa and Mississippi across two growing seasons. The results show that glyphosate is detected 60-100% of […]

Monsanto GM Corn Falls Prey to Bug It Was Suppose to Thwart, Threatening Organic

(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 […]

New Study Links Pesticide Exposure to Prostate Cancer

(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.
