Ten-Year-Old Suffers Traumatic Brain Injury After Home Treated with Pesticide

(Beyond Pesticides September 9, 2015) A young Florida boy and his family are reeling after a routine termite treatment resulted in a devastating outcome. Ten-year-old Peyton McCaughey of Palm City, Florida has been in the hospital for weeks following a severe reaction to chemicals used to fumigate his family’s home. According to news reports, the  fumigation was performed by Sunland Pest Control, a subcontractor of Terminix. The Florida Department of Agriculture has since issued a “Stop Work Order” while it  investigates the company in collaboration with the Environmental Protection Agency (EPA) and the state Department of Health. After returning to their home hours after the Terminix subcontractor told them it was safe to enter, the whole family became very ill. While the parents and the 7-year-old daughter recovered, the young boy’s condition continued to worsen. “He was having some uncontrollable muscle movements, couldn’t stand up, couldn’t speak, so they took him to a local walk-in and the doctor quickly recognized it was probably poisoning from a treatment,” said Peyton’s uncle, Ed Gribben. Current reports indicate that the boy has likely suffered brain damage and has lost all muscle control, rendering him unable to stand or speak. He remains in a […]

Lice Found Resistant to Common Insecticide Treatment

(Beyond Pesticides, August 20, 2015) Just as children go  back to school, research  finds that lice in 25 of 30 states in a  U.S. study have developed resistance to common over-the-counter treatments like permethrin, calling into questions the justification for exposing children to a neurotoxic and carcinogenic pesticide and elevating the need to consider nontoxic alternatives. The  research was presented Tuesday at the 250th National Meeting and Exposition of the American Chemical Society (ACS), by Kyong Yoon, Ph.D., of Southern Illinois University, Edwardsville. Classified as a synthetic pyrethroid insecticide, permethrin is “likely carcinogenic” and a suspected endocrine disruptor, immunotoxic, neurotoxic, and highly toxic to fish, aquatic animals, and bees. Dr. Yoon and his colleagues describe the threefold mutations that lice have developed over time due to the constant use of synthetic pyrethroid insecticides. This new finding builds on his team’s previous research, which found that 99.6% of lice are resistant to chemical treatment, adding weight to the fact that chemical treatments not only are unnecessary given effective least-toxic alternatives, but also are not able to provide the lice control that manufacturers claim. “We are the first group to collect lice samples from a large number of populations across the U.S.,” […]

Mosquito Fogging Kills Hundreds of Bees

(Beyond Pesticides, August 19, 2015) Local fogging for  mosquito control turned tragic for a Palo Alto, California beekeeper who lost hundreds of honey bees from his backyard hives. The beekeeper, who also produces organic honey, now fears his honey is contaminated. The fogging, which occurred last month, was in response to positive tests for West Nile virus in mosquito samples. Many mosquito control pesticides are toxic to honey bees and given the declining populations of pollinators, vector control officials are being asked to carefully consider the risks associated with pesticide spraying. According to the local NBC affiliate, beekeeper Rondolph Tsien believes he was not given sufficient time to protect his bees from the mosquito fogging and, despite trying to cover his hives with a tarp to protect his bees from drifting pesticides, many were lost. A mosquito sample tested positive for West Nile virus about one mile from Mr. Tsien’s home, putting his property in the catchment area for fogging. Mr. Tsien worries the surviving bees will produce contaminated honey that can no longer be labeled organic. A Santa Clara County Vector Control representative stated during an interview that the county uses  an “extremely low dose” of pesticides during fogging […]

Despite Known Hazards, EPA Waits Decades for Manufacturers to Withdraw Pesticide

(Beyond Pesticides, July 8, 2015)  Last week, after decades of review and known toxic hazards, especially to children, the Environmental Protection Agency (EPA) accepted a proposed cancellation for  a number of indoor uses (including food establishments) and tolerances of propoxur, a carbamate insecticide known for its toxic effects to  children. EPA has received a Section 6(f) request under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) from the registrant of propoxur to voluntarily cancel certain uses of the carbamate insecticide. The request from the manufacturer, Wellmark International, requests cancellation of  indoor aerosol, spray and liquid formulations of propoxur, indoor crack and crevice use, and all use in food-handling establishments.  EPA previously agreed to an April 1, 2016 phase out of propoxur in pet collars, but has continued to leave open these other avenues of exposure. The agency will begin accepting comments on its  proposal once it has been published in the Federal Register, which is expected to occur within 10 days of the prepublication signature date. It should be noted that EPA engages in lengthy negotiations with pesticide manufacturers, as is the case with propoxur (see recent announcement on chlorpyrifos), rather than pursuing rigorous regulatory standards through its cancellation or […]

Popular Weed Killer 2,4-D and Lice Treatment Lindane Classified as Carcinogens

(Beyond Pesticides, June 24, 2015) The International Agency for Research on Cancer (IARC) has found that there is some evidence in experimental animals that the popular herbicide, 2,4-D, is linked to cancer and now classifies it as a Group 2B, “possibly carcinogenic to humans.” IARC also classified lindane, used commonly in the U.S. as a topical lice treatment, in Group 1,“carcinogenic to humans” based on sufficient evidence in humans with the onset of non-Hodgkin lymphoma (NHL). These latest cancer findings come just months after the agency classified the world’s most widely used herbicide, glyphosate (Roundup), as “probably carcinogenic to humans,” raising public concerns on the lack of action from U.S. regulators. This month, 26 experts from 13 countries met at the World Health Organization’s (WHO) IARC in Lyon, France to assess the carcinogenicity of the insecticide lindane, the herbicide 2,4-D, and insecticide DDT. The findings are published in the Lancet. The new IARC findings come months after the agency classified glyphosate, the ingredient in the popular Roundup weed killer, as a Group 2A “probable” carcinogen, citing sufficient evidence of carcinogenicity based on laboratory studies. This decision sparked renewed calls for the U.S. Environmental Protection Agency (EPA) to take action on […]

Cornell University Releases GE Moths without Thorough Evaluation of Risks

(Beyond Pesticides, June 12, 2015) Without input from or notification to the public, Cornell University  has released genetically engineered (GE) diamondback moths at its  agricultural experiment station in Geneva, New York. The university is testing a new way to  control agricultural  pests, much to the dismay of environmentalists. The moths, which are engineered to be autocidal (self-killing), pose a possible threat to the certification of organic farmers and create environmental risks. Environmental groups such as Food and Water Watch, Center for Food Safety, and Friends of the Earth, among others, sent a letter expressing concern over the U.S. Department of Agriculture (USDA)’s assessment process, which neglected to address  the possibility of moth movement past the trial area, and the impacts that diamondback moth declines will have on their natural predators and the larger ecosystem. These groups are recommending that  all outdoor trials be stopped until more information is available. Cornell has partnered with Oxitec, a self-described  pioneer in using advanced genetics to control target  insects. They plan on controlling the population growth of these GE moths through their genetic design that kills the moth  in the larval stage on plants. Normally, these larvae feed on crops such as broccoli and […]

Study Shows Neonicotinoid Pesticide Has Devastating Effect on Termites Due to Eusocial Behavior, Similar to Bees

(Beyond Pesticides, May 26, 2015) A study led by Purdue University Entomology Professor Michael Scharf, Ph.D. finds that small doses of imidacloprid, a neonicotinoid pesticide, can halt the normal functioning of termite behavior, leaving colonies vulnerable to disease and eventual death. While this effect may be celebrated by the pesticide industry as a victory for termite control, it has serious implications for the use of imidacloprid and other neonicotinoid pesticides on all eusocial insects, such as ants and bees. Eusocial insects thrive as a colony, working, living and sometimes even fighting diseases as one organism, rather than as many individuals existing together. Termites, specifically, exhibit a remarkable resistance to many diseases because they engage in social grooming, clearing pathogens off of one another. Other examples of eusociality can be found in ant and bee colonies. Ant colonies create foraging trails and engage in cooperative transport, where they create long chains of ant individuals to form a whole assembly line to transport food back to the colony and work as one to carry large prey that would not be otherwise attainable. Honeybee colonies send out foragers to report back with the location of plentiful food sources so that other bees know […]

Canada Fights Toxic Mosquito Spraying Near Homes and Parks

(Beyond Pesticides, April 20, 2015) New details emerged last week after a Canadian volunteer group, Pesticide Free Alberta (PFA), received records from the City of Edmonton regarding ground and aerial application of Dursban 2.5, a restricted insecticide (in both Canada and the US), in close proximity to residential areas to kill off mosquito larvae. The coordinator of PFA, Sheryl McCumsey, fought for months for the data to be released. Health Canada does not recommend using Dursban in areas where children will be exposed, such as homes, parks, school grounds or playing fields, but the City of Edmonton justifies the use of the product by its label language, citing that it can be used in industrial areas. These areas often end up bordering residential neighborhoods and natural lands, such as parks. The active ingredient in Dursban is chlorpyrifos, a neurotoxic insecticide that has been linked to many detrimental health and environmental effects, such as endocrine disruption, reproductive and birth effects, toxicity to birds, bees and aquatic wildlife.In the US, the Environmental Protection Agency (EPA) and Dow AgroSciences restricted the sale and use of most home, lawn and garden product due to its health risks for children. However, it is still used […]

Chemical Landscape and Nursery Industry Says Bee Friendly Habitat “Not Viable”

(Beyond Pesticides, March 11, 2015)   The White House’s recommendations for pollinator-friendly landscaping at federal facilities are “largely unachievable,” according to trade groups AmericanHort and the Society of American Florists. The groups believe that growing plants that attract and feed honey bees, wild bees, butterflies and other pollinators without a reliance on persistent, systemic and toxic pesticides that can harm them is “not a viable recommendation.” This comes in spite of several initiatives already taken by nurseries across the country to limit or restrict the use of systemic neonicotinoid pesticides on nursery and ornamental plant production. Last fall, the White House Council on Environmental Quality (CEQ) announced new guidelines for federal agencies to incorporate pollinator friendly practices at federal facilities and on federal lands. Critical to pollinator health within these guidelines is a requirement that agencies should “[a]cquire seeds and plants from nurseries that do not treat their plants with systemic insecticides.” Further, the document states that, “Chemical controls that can adversely affect pollinator populations should not be applied in pollinator habitats. This includes herbicides, broad spectrum contact and systemic insecticides, and some fungicides.” Concurrent with CEQ’s announcement, the General Services Administration (GSA) also stated it is in the process […]

Emergency Use of Bee-Killing Pesticide Approved for Florida Citrus

(Beyond Pesticides, February 26, 2015) Yesterday, the Environmental Protection Agency (EPA) granted Florida citrus growers an emergency exemption to use the bee-killing pesticide clothianidin to control Asian Citrus Psyllid (ACP), a pest that causes “citrus greening,” a devastating citrus plant disease. Clothianidin, which is not currently registered for use on citrus, is part of a class of neurotoxic, systemic insecticides called neonicotinoids, which have been implicated in global honey bee declines and suspended in the European Union. “EPA needs to assist in stopping the deadly use of pesticides that harm bees, butterflies, and birds with sustainable practices, rather than imperil pollinators with its decisions,” said Jay Feldman, executive director of Beyond Pesticides, a health and environmental advocacy group. He continued, “We understand the immediate chemical needs of chemical-intensive agriculture for increasingly toxic and persistent chemicals, but urge EPA to help stop the treadmill, lest it allow irreversible harm to the environment, biodiversity, and human health.” Beyond Pesticides is urging EPA to require that growers adopt a management plan in order to apply clothianidin. “Ultimately, EPA should be requiring growers to adopt integrated organic systems to manage pests, as a part of an emergency permit,” said Mr. Feldman.

Florida Officials, FDA, Consider Release of Genetically Engineered Mosquitoes

(Beyond Pesticides, February 3, 2015) Officials in the Florida Keys are seeking approval from the U.S. Food and Drug Administration (FDA) to release a wave of mosquitoes that have been genetically engineered to produce offspring whose larvae are unable to survive. The plan to introduce these mosquitoes has been met with intense skepticism by local residents. A change.org petition against the release has garnered over 146,000 signatures to date. Florida Keys Mosquito Control District (FKMCD) officials have been planning the release alongside British biotechnology company Oxitec, which has already conducted similar experiments with the genetically engineered (GE) mosquitoes in Brazil and the Cayman Islands. Websites for Oxitec and the FKMCD assert that the GE aedes aegypti mosquitoes will significantly lower the numbers of the disease spreading insects, and reduce the need to spray insecticides. Opponents counter that the introduction of the modified mosquitoes is unacceptably risky, as there has been little research on possible non-target effects of the novel insect, and current control methods and public education have been successful at controlling exotic diseases. Opportunity for public comment to FDA and the U.S. Centers for Disease Control and Prevention is likely to occur in the near future. Behind the Technology […]

School’s Back in Session, Leave the Toxins Behind

(Beyond Pesticides, August 28, 2014) It’s back to school time again, which for many of our readers and parents across the country means the unnerving possibility of hazardous pesticide exposure at school from well-intentioned but misguided attempts to create a germ and pest-free environment. Because children face unique hazards from pesticide exposure due to their small size and developing organ systems, using toxic chemicals to get rid of pests and germs harms students much more than it helps. Fortunately, parents and teachers have many options for safer techniques and strategies to implement a pest management program at schools without relying on these toxic chemicals. Additionally, schools can further their students’ education beyond the lessons of the text book by providing habitat for wildlife and growing organic food in a school garden.  By going organic, your child’s school can become a model for communities across the nation. Beyond Pesticides has put together this back-to-school checklist of programs and steps you can take to ensure that you are sending your kids back to a healthier and safer environment.

New Research Links Pesticide Exposure to Adverse Effects Three Generations Later

(Beyond Pesticides, July 28, 2014) New research from Michael Skinner, Ph.D.’s laboratory out of Washington State University finds that —yet again”” exposure to pesticides may have devastating consequences for future generations. The study, “Pesticide Methoxychlor Promotes the Epigenetic Transgenerational Inheritance of Adult-Onset Disease through the Female Germline,” published in PLOS ONE, finds that gestating rats exposed to the pesticide methoxychlor develop a higher incidence of kidney disease, ovary disease and obesity in offspring spanning three generations. The incidence of multiple diseases increased in the third generation or “great-grandchildren.” This study suggests that ancestral exposures to methoxychlor over the past 50 years in North America may play a part in today’s increasing rates of obesity and disease. The epigenetic changes observed were specific to methoxychlor exposure and, according to researchers, may prove to be valuable biomarkers for future research on transgenerational disease. For people exposed to the pesticide, Dr. Skinner says his findings have implications such as reduced fertility, increased adult onset disease and the potential to pass on those conditions to subsequent generations. “What your great-grandmother was exposed to during pregnancy, like the pesticide methoxychlor, may promote a dramatic increase in your susceptibility to develop disease, and you will pass […]

UK Bread Contaminated with Pesticides

(Beyond Pesticides, July 21, 2014) According to figures released by the British Government last week, over 60% of the county’s bread supply is tainted with pesticide residues. This is a shocking increase from numbers recorded in 2001, which found 28% of bread to be tainted. According to the Department for Environment, Food and Rural Affairs (Defra) Expert Committee on Pesticides Residues in Food (PRIF), 2,951 bread samples were tested. According to a Pesticide Action Network UK report, a majority of the reoccurring pesticides were glyphosate and chlormequat. Glyphosate is an herbicide that can lead to non-Hodgkin’s Lymphoma, genetic damage, cancer, reproductive issues, liver damage, and endocrine disruption as well environmental damage such as water contamination and harmful effects to amphibians. Unfortunately, very little research has been done on what the effects can be on humans. Chlormequat, the second most-commonly found pesticide in British bread, is a plant growth regulator. A study conducted by the UN’s Food and Agriculture Organization (FAO) linked Chlormequat to developmental toxicity in animals. Very little research has been performed assessing the public health impact of this pesticide. In the U.S., it is only allowed for use on ornamental plants. Pan UK spokesman Nick Mole said, “The […]

Virginia County Stops Pesticide Spraying in Favor of Alternatives to Combat Lyme Disease

(Beyond Pesticides, July 18, 2014) After years of struggling to combat the rise of Lyme disease in the region, Loudoun County, Virginia has decided to forgo the spraying of a hazardous pesticide in public parks in favor of public education and continued surveillance of park lands. Controversy over spraying arose back in 2012 when Loudoun began ramping its spray program to manage ticks, often the carrier of the disease. Loudon County used the pesticide Talstar, which contains the active ingredient bifenthrin, a neurotoxic chemical whose use raises public health and product efficacy concerns, as documented by the Centers for Disease Control and Prevention. Beekeepers expressed concern that spraying would greatly damage their bee colonies, as bifenthrin is highly toxic to bees, while conservationists were concerned with the chemicals leaching into waterways and killing aquatic life. At the same time, some researchers point out that there was no evidence that spraying the chemical would reduce the number of Lyme disease infections. After years of debate and data analysis,  David Goodfriend, M.D., M.P.H, director of the Loudoun County Health Department, said that the county’s Lyme Disease Commission’s recommendation was to not spray any of the properties. The recommendation was based on two […]

Scientist Warns of Ecological Effects Associated with Lawn Care Pesticide Runoff

(Beyond Pesticides, June 9, 2014) A recent talk given by Donald Weston, PhD, a professor emeritus in UC Berkeley’s Department of Integrative Biology, to a community group in San Jose, California warned residents about the dangers that  lawn care insecticides present to  local aquatic life. The talk focused on the problems synthetic pyrethroids and fipronil can have on Hyalella azteca and Chironomus dilutes. Increasing levels of pesticide runoff in local stream systems have not only led to decreased populations of these aquatic crustaceans, but also populations that have become resistant to pesticides. Aquatic invertebrates are extremely sensitive to pesticide runoff and different states around the country have struggled with creating pesticide regulations that foster a healthy aquatic ecosystem. A good way to reduce pesticide runoff is to transition away from toxic land care methods and adopt organic practices. Hyalella crustaceans, a tiny shrimp-like animal, are hypersensitive to pyrethroids, which are a class of insecticides used by professional lawn care companies and found in common products like Raid and mixed with fertilizer products like Scotts Turf Builder under the name SummerGuard. Chironomus dilutes, a red worm-like invertebrate, is sensitive to fipronil, which is used to kill fleas on dogs and cats […]

USDA Advances Biological Controls for Citrus Greening Disease

(Beyond Pesticides, May 15, 2014) Last week, the U.S. Department of Agriculture (USDA) announced  that it is broadening the use of tiny parasitic wasps, Tamarixia Radiata, to combat the rampant problem  of Huanglongbing, also known as citrus greening disease, which has killed thousands of orange trees in Florida. The citrus industry is valued at $2 billion dollars. Citrus greening is an incurable disease that is spread by the Asian citrus psyllid. Symptoms of this disease include yellow shoots, uneven discolored patches, and deficiencies with chlorophyll production. Chlorophyll is the green pigment found within plants. It is extremely important for photosynthesis, which allows plants to absorb energy from the sun. The disease is usually found in warmer climates like Asia, India and the Saudi Arabian Peninsula; however, it made its way to Florida in 1998 and is now endangering California’s citrus industry. USDA has already committed to provide $1.5 million dollars to the T. radiata  breeding and release program in California, Texas, and Florida. Congress has also allocated more than $125 million dollars over the next five years to fund more research on containing the spread of the Asian citrus psyllid. Although the psyllids do not directly kill citrus trees, they […]

California Bans Controversial d-CON Products as EPA Stalled by Manufacturer

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

Scientists Determine 99.6% of Lice Resistant to Chemical Treatment

(Beyond Pesticides, March 10, 2014)  Virtually all lice in the U.S. have developed resistance to over-the-counter and prescription shampoos containing the toxic chemical permethrin. The U.S. Environmental Protection Agency’s Office of Pesticide Programs  considers permethrin, part of the synthetic pyrethroid class of chemicals, “likely to be carcinogenic.” However, when used as a lice shampoo the chemical is regulated by the Food and Drug Administration and allowed for use on infants over two months old. The latest study on lice resistance, published in the Journal of the Entomological Society of America, shows that harsh chemical treatments not only are not necessary given effective least-toxic alternatives, but also are not able to provide the lice control that manufacturers claim. “In the UK and Europe, they don’t even use pyrethroids anymore. Virtually everyone but the United States and Canada has given up using these over-the-counter products,” said Dr. John Clark, PhD, a professor of environmental toxicology and chemistry at the University of Massachusetts Amherst and co-author of the new study. In an interview with the Detroit Free Press,  Eric Ayers, MD of the Children’s Hospital of Michigan noted that lice that are not killed by the chemical treatment not only survive, but become […]

Research on Corn Pest Finds No Economic Benefit to GE Corn in the Northeast

(Beyond Pesticides, January 3, 2014) A recent study on the European corn borer (ECB), a major corn pest, finds no significant difference in yield between genetically engineered (GE)Bt (ECB-resistant) corn and non-GE corn in the Northeast, where pest pressure has decreased. Considering the high cost of GE corn, researchers determine that farmers will see no benefits in terms of profit. The study, published in the journal Pest Management Science, examines the damage that ECBs cause to crops, comparing corn genetically engineered to express the insecticidal toxin Bacillus Thuringiensis (Bt) with non-Bt crops at 29 sites around Pennsylvania over three years. The study concludes that although Bt corn hybrids reduced ECB damage in comparison to non-Bt crops, they found no difference in yields, explaining that because of higher seed costs they also “rarely improved profits.” Although researchers attribute the decline in ECB population to the adoption of Bt corn, the study does not address long-term insect resistance which can develop in fields after the introduction of GE crops and lead to an increased use in pesticides. “With less ECB damage around, non-Bt hybrids in our tests yielded just as well as Bt hybrids, so the decline in ECB populations provides an […]

Multi-generational Effects of DDT Linked to Obesity

(Beyond Pesticides, October 28, 2013) Scientists at Washington State University (WSU), in a laboratory study,  determined that exposure to the insecticide DDT ””banned in the U.S. since 1972, but still used today in developing countries for malaria abatement programs””impacts multiple generations, ultimately contributing to obesity three generations down the line. The study, published in the journal BMC Medicine, provides the scientific community with new information on multi-generational impacts of pesticide exposure. Lead researcher Michael Skinner, PhD., professor of biological sciences at WSU, and colleagues exposed pregnant rats to DDT to determine the long-term impacts to health across generations. The study, Ancestral dichlorodiphenyltrichloroethane (DDT) exposure promotes epigenetic transgenerational inheritance of obesity, finds that the first generation of rats’ offspring developed severe health problems, ranging from kidney disease, prostate disease, and ovary disease, to tumor development. Interestingly, by the third generation more than half of the rats have increased levels of weight gain and fat storage. In other words, the great grandchildren of the exposed rats are much more likely to be obese. “Therefore, your ancestors’ environmental exposures may influence your disease development even though you have never had a direct exposure,” the study finds. Previous studies have demonstrated that exposure to […]

Another Study Finds Rootworms Resistant to Genetically Engineered Corn

(Beyond Pesticides, September 3, 2013) For the past several years, corn rootworms  have  been widely reported to exhibit resistance  to corn genetically engineered (GE) with the Bacillus thuringiensis (Bt) toxin. A  new report by  University of Illinois researchers found the resistant corn rootworm  in two of the state’s counties significantly damaged by western corn rootworm. The increasing lack of efficacy of GE corn, developed with the claim that it  is specifically designed to protect corn from rootworm, calls into question the efforts of agrichemical companies to patent new forms of GE crops. The report by Joe Spencer, PhD, and Michael Gray, PhD,  identifies significant damage from western corn rootworms in farm field that were planted with GE corn that contain a Bt protein referred to as “Cry3Bb1,” which has been inserted into nearly one-third of the corn planted in the United States. This version of Bt corn was introduced by Monsanto in 2003, and was touted as a way to reduce insecticide use against rootworm pests. Evidence was gathered in two Illinois counties, Livingston and Kankakee, after fields that had severe root pruning and lodging were brought to the attention of Drs. Spencer and Gray. Dr. Gray was quoted in […]

CDC Study Finds Pesticide Ineffective at Stopping the Spread of Lyme Disease

(Beyond Pesticides, August 26, 2013) A recent study presented by the Centers for Disease Control and Prevention (CDC)   at the International Conference on Lyme Borreliosis and other Tick-Borne Diseases in Boston finds that spraying lawns with the insecticide bifenthrin does not reduce the incidence of tick-borne diseases. The study could have important policy implications for towns and communities that are feeling pressure to spray as prevalence of tick-borne diseases, such as Lyme disease, continue to rise.  There are least-toxic alternative management strategies that are effective and safer than chemical controls. The recently released study by CDC included 2,500 households in Fairfield, Litchfield, and New Haven Counties in Connecticut; Dutchess County in New York; and four counties in Maryland. Half of the households’ lawns were sprayed with bifenthrin and the other half was sprayed with water as a control. The study, conducted over two years, found that the households that were sprayed with bifentrhin saw a 60 percent reduction in ticks on their propriety but still had similar levels of tick encounters and tick-borne illnesses. These final results are similar to the results the study found after its first year.   This research reveals that using pesticides is not an […]
