(Beyond Pesticides, August 22, 2016) An invasive whitefly that is resistant to pesticides has been found outdoors in the U.S. for the first time, prompting a public discussion hosted by the University of Florida Extension Miami-Dade in Homestead, Florida on July 29. And while the fears amongst fruit and vegetable growers over crop devastation are valid, little attention has been paid to the viability and effectiveness of organic and cultural management practices in preventing and managing  whiteflies. Meanwhile, chemical intensive agriculture, which is dependent on insecticides to control whiteflies, is harming the same beneficial insects that act as natural predators to the whitefly. The pest, a Q-biotype of the sweet potato whitefly, Bemisia tabaci, has been present in greenhouses around the U.S. since 2004, when it was first found in Arizona. According to Florida Agriculture Commissioner Adam Putnam, this pest “poses a serious risk to Florida’s $120 billion agriculture industry and the more than two million jobs it supports.” Whiteflies are tiny, fluid-sucking insects that thrive in warm weather and become abundant in ornamental and vegetable plantings. This particular species breed year round and large colonies often develop on the undersides of leaves. Whiteflies draw fluid of out a plant […]

(Beyond Pesticides, August 19, 2016) A study published earlier this week has found that the increasing use of neonicotinoid (neonic) insecticides is correlated with a steep decline in butterfly health and reproductive success — as more neonics are used, butterflies are struggling to survive. This study adds to previous evidence that demonstrates, in addition to bees, neonics can cause serious harm to other important pollinators. The study, Increasing neonicotinoid use and the declining butterfly fauna of lowland California, looks at 67 species of butterfly fauna in the lowlands of Northern California at four sites that were  monitored for approximately 30-40 years. The sites include Suisun Marsh, West Sacramento, North Sacramento, and Rancho Cordova. While controlling for land use and other factors, the researchers found a correlation between butterfly population decline and increasing neonic applications, which also appeared to be more severe for smaller-bodied species. According to the researchers, the results suggest that neonics could influence non-target insect populations when applied nearby. This study contributes to the mounting evidence that neonicotinoid insecticides are linked to pollinator decline. Neonics have increasingly been the subject of studies that highlight a relationship between neonicotinoid exposure  and harmful effects to pollinators. These effects are being […]

(Beyond Pesticides, August 18, 2016)   Decline of wild bee populations is linked to the use of toxic, systemic neonicotinoid (neonic) pesticides used on oilseed rape (canola), according to new research done by a team of scientists at the Centre for Ecology and Hydrology in the United Kingdom. In addition to corn and soybeans, canola is one of the main crops treated with neonicotinoids worldwide. Neonic pesticides have long been identified as a major culprit in bee decline by independent scientists and beekeepers, yet chemical manufacturers like Bayer and Syngenta have focused on  other issues such as the varroa mite. As Beyond Pesticides put it in the spring 2014 issue of Pesticides and You, the issue of pollinator decline is No Longer a Big Mystery, and urgent action is needed now to protect pollinators from these toxic pesticides. Neonics are associated with decreased learning, foraging and navigational ability, as well as increased vulnerability to pathogens and parasites as a result of suppressed bee immune systems. In addition to toxicity to bees, pesticides like neonicotinoids have been shown to also adversely affect birds, aquatic organisms and contaminate soil and waterways, and overall biodiversity. The study, Impacts of neonicotinoid use on long-term […]

(Beyond Pesticides, August 17, 2016) In response to dramatic scientific findings, a severe decline in bee populations, and growing public demand for bee-safe plants, a new report confirms  the decision  of  major retailers to phase-out  the sale of flowers and trees treated with the pesticides most closely associated with the decline —neonicotinoids. A new report released by Friends of the Earth, analyzes plants purchased at  Home Depot,  Lowe’s, Ace Hardware,  True Value  and  Walmart. Many of these major retailers have made public commitments to stop selling bee-toxic neonicotinoids and treated plants. Additionally, the states of Maryland and Connecticut have passed legislation that stops the retail sales of neonics. The report,  Gardeners Beware 2016, released yesterday is a follow-up to previous testing that demonstrated the presence of bee-toxic neonicotinoid insecticides in more than half of bee-attractive flowers tested. The 2016 analysis found that 23 percent of flowers and trees tested contain neonicotinoid insecticides at levels that can harm or kill bees, compared to 51 percent in 2014, indicating that stores are selling far fewer plants treated with bee-killing neonics. This reduction is likely due to changes in store policies that commit retailers to eliminate neonicotinoid use on garden plants. Retailer commitments […]

(Beyond Pesticides, August 16, 2016) Young children are disproportionately poisoned by toxic pesticides used indoors, according to a study published in the Australian and New Zealand Journal of Public Health. Data analyzed from the Queensland, Australia Poisons Information Centre (QPIC) finds that 49% of 743 insecticide-related calls in 2014 concerned young children. Given that children are more sensitive to pesticide exposure than adults because they take in more of a chemical relative to their body size and have developing organ systems, this data underscores the importance of educating the general public about alternatives to the use of toxic pesticides in and around the home. A significant share of childhood pesticide poisonings occurred in very young children. “Children in the one-year age group were at greatest risk — as they’re at that stage where they spend a lot of the time on the floor and put things in their mouth,” said Karin English, PhD candidate at the University of Queensland. As a result of children’s propensity for hand to mouth motion, cockroach baits and ant liquid were found to be the most common source of insecticide exposure for kids under five, covering 39% of calls. However, Ms. English notes that enclosing […]

(Beyond Pesticides, August 14, 2016) According to recent reports, the illegal misuse of pesticides in Dubai has left ten people dead within the last year. The culprit? Domestic use of a pesticide containing highly toxic aluminum phosphide sold on the black market, touted as a way to fight bed bugs for low-income families that may not have the education level or means to research and pursue other options. While the government acknowledges a significant problem given the common occurrence of these  deaths, those in positions of power are admittedly at a loss when it comes to finding a solution, with some calling for a crack down on those selling the pesticides illegally, and others wanting to punish those that buy and use it. Regardless of the actions, elected officials decide to pursue, embracing organic pest management systems, as well as a robust education campaign, will be critical in curbing these deaths. Given the availability of greener, safer alternatives, Beyond Pesticides opposes any registration or allowance of phosphide fumigants and other highly toxic chemicals that can be easily misused. Phosphide fumigants, including aluminum phosphide, are known to be acutely toxic when ingested or inhaled. Symptoms of mild to moderate acute exposure […]

(Beyond Pesticides, August 12, 2016) A new study by a team of scientists at Virginia Tech finds that commonly used in-hive pesticides result in changes to the honey bee gut microbiome. The study, Honey bee gut microbiome is altered by in-hive pesticide exposures, was led by Virginia Tech associate professor of horticulture, Mark Williams, Ph.D., and colleagues from Oregon State University and North Carolina State University. This research, published several weeks ago in the journal Frontiers in Microbiology, aimed to determine the microbiome of honey bees (Apis mellifera) after being exposed to three common pesticides. Coumaphos and tau-fluvalinate, both common miticides used in conventional beekeeping, and chlorothalonil, a fungicide commonly detected in hives, were used as pesticide treatments in the study. While this  research contributes to the already established body of science on the complexity of pesticide exposure effects, beekeepers reported the steepest, and then sustained, declines in honey bee populations after the large  increase in  neonicotinoid pesticide  use in the early 2000’s. Beekeepers nationwide suffered  their highest hive losses of 44.1% in the last national survey from April 2015-2016. While it is likely that neonicotinoids are not the sole factor in pollinator decline, they have been found to exacerbate […]

(Beyond Pesticides, August 10, 2016) New research connects 78 pesticides commonly used by farmers with many adverse respiratory effects, including both allergic and non-allergic wheeze. The study, Pesticides Are Associated with Allergic and Non-Allergic Wheeze among Male Farmers, was led by NC State environmental epidemiologist, Jane Hoppin, ScD and colleagues from the National Institute of Environmental Health Sciences (NIEHS), the National Cancer Institute, Westat and the National Institute for Occupational Safety and Health (NIOSH). This is one of the most comprehensive evaluations of pesticides in relation to wheeze that has been evaluated to date, finding that several commonly used pesticides in both agriculture and residential settings can cause adverse respiratory effects. “Fifty-one of the pesticides we tested in this study had never been analyzed in terms of their effects on respiratory outcomes. And some of them, like glyphosate, 2,4-D and permethrin, aren’t just used on farms. They’re used residentially now to kill weeds or treat fleas on pets,” said Dr. Hoppin. “We believe it’s important information that will help people make decisions about pesticides.” Researchers used interview data from the 2005-2010 Agricultural Health Study (AHS) to assess the correlation between pesticide exposure and wheeze in male farmers. 22,134 farmers were […]

(Beyond Pesticides, August 10, 2016) In a letter, submitted by the Soil Association, leading bread producers and supermarkets in the United Kingdom (UK) are being urged to cease stocking and selling bread products that  contain traces of the herbicide glyphosate. Glyphosate, the active ingredient in Monsanto’s Roundup, has been classified as a probable human carcinogen by the World Health Organization (WHO) and is linked to numerous other environmental and human health concerns. Glyphosate residues have already been detected in bread, beer, and wine. The Soil Association, a UK organization that campaigns for healthy, humane and sustainable food, farming and land use, is concerned that glyphosate is used on crops immediately before harvest, and subsequently makes its way into food. According to the letter and a spokesperson for the group, “Using glyphosate, and glyphosate-based products, as a pre-harvest treatment is fundamentally wrong, and we are calling for an end to it with our campaign.  Wheat harvest will start in the next few weeks, and we are asking bread companies to act now and put a stop to glyphosate as a pre-harvest desiccant in their supply chains. The EU has just advised glyphosate use as a pre-harvest spray on food crops should […]

(Beyond Pesticides, August 9, 2016) Farmers in Missouri, Arkansas, and Tennessee are confronting widespread crop damage and bracing for lower yields as a result of agrichemical giant Monsanto’s botched roll-out of new genetically engineered soybean and cotton crops. The company, whose current line of glyphosate-tolerant crops are failing to control weeds throughout the U.S. and across the globe, developed a new line of soybean and cotton with traits that make it tolerate applications of an older herbicide dicamba. However, while its seeds are available for purchase on the market, and Monsanto is encouraging farmers to grow them, the company has yet to receive EPA regulatory approval for the dicamba herbicide meant to be used with the plants. A spate of news reports over the past two  months in southern soybean growing regions finds that many farmers are illegally applying off-label dicamba-based herbicides to Monsanto’s new GE crops in an effort to control weeds resistant to glyphosate. Use of this highly volatile herbicide is causing widespread crop damage not only to soybeans that don’t carry the resistance trait, but other crops in the region, including peaches, melons, and tomatoes. Dicamba has a strong propensity to volatilize small particles of the herbicide […]

(Beyond Pesticides, August 8, 2016) Last week, the Environmental Protection Agency (EPA) received a  letter  from Earthjustice requesting that the agency notify the Hawaii State Department of Agriculture (HDOA) of its chronic failure to meet statutory duties for pesticides regulation and enforcement under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and, if timely corrections are not made, to rescind HDOA’s primary enforcement authority completely. Earthjustice has asked EPA to immediately notify HDOA that it has failed to carry out its responsibilities, and, pursuant to FIFRA, to give the agency 90 days to correct its overwhelming shortcomings. If the problems, which include failure to enforce pesticide use violations and a large backlog of pesticide complaints and investigations dating back to as early as 2008, are not corrected and addressed within 90 days, Earthjustice requests that EPA revoke HDOA’s primary enforcement authority indefinitely.  In the event that HDOA’s authority to regulate is stripped, EPA would then take over the responsibility for enforcing pesticide use violations occurring within the state. Under FIFRA,  the federal statutory authority for  pesticide approval and use, EPA may  delegate to  a state primary responsibility for enforcing pesticide use violations if thestate has adequate pesticide laws and adequate […]

(Beyond Pesticides, August 2, 2016) The Environmental Protection Agency’s (EPA) Environmental Appeals Board (EAB) has upheld an earlier ruling by EPA’s chief administrative law judge, Susan Biro, to cancel sales of the conditionally registered insecticide flubendiamide, produced by Bayer CropScience, which was conclusively found  to be highly toxic to freshwater wildlife after EPA allowed its use on 200 crops. The situation has left many questioning why the agency did not wait to register the product until it had complete data. The EAB disagreed with the Office of Pesticide Programs  and Judge Biro’s decision regarding existing stocks of the insecticide product, and ruled that farmers and other users, retailers, and distributors (not the manufacturers) will be allowed to use and sell existing supplies of the chemical. This controversy points to what health and environmental advocates cite as a fundamental flaw  in EPA’s pesticide registration review —the agency’s conditional pesticide registration process, which allows toxic pesticides  on the market without a complete and comprehensive assessment  of their  potential  harm””in this case to  wildlife and the vital ecosystem services they provide. Despite its agreement with EPA, Bayer said in March it would fight the EPA decision, which it appealed to the EAB. But, […]

(Beyond Pesticides, July 29, 2016)  A study released earlier this week finds lower IQ (intelligence quotient) in children born to mothers who during their pregnancy were living in close proximity to chemical-intensive agricultural lands where organophosphate pesticides were used. This study adds to the body of scientific literature that links prenatal exposure to organophosphate pesticides with lower IQ’s in children. Organophosphate pesticides, a relatively older generation of highly neurotoxic pesticides still widely used on farms in California, have been associated with a  broad range of diseases  in both children and adults.  This  latest study  supports health and environmental advocates’ call to eliminate these toxic pesticides in agriculture and move toward safer, sustainable, and organic management practices. The study, titled  Prenatal Residential Proximity to Agricultural Pesticide Use and IQ in 7-Year-Old Children, looks at 283 women and children from the agricultural Salinas Valley who are enrolled in the long-term Center for the Health of Mothers and Children in Salinas (CHAMACOS) study. Specifically, researchers looked at pregnant women living within one kilometer of agricultural fields where organophosphate pesticides were used. They found that at age 7, the children of those women had declines of approximately two IQ points and three verbal reasoning […]

(Beyond Pesticides, July 28, 2016)   Led by the Institute of Bee Health at the University of Bern, new research finds evidence that two commonly used neonicotinoid (neonic) insecticides have a significant adverse effect on the reproductive ability of male honey bees (drones) and queen bees in managed and wild colonies. The study,  Neonicotinoid insecticides can serve as inadvertent insect contraceptives, published in  Royal Society Journal Proceedings B, focuses on the differences in lifespan and viability of sperm throughout exposed and unexposed drones. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have incurred ongoing and rapid population declines from hive abandonment and bee die-off in a phenomenon known as colony collapse disorder (CCD).  Neonicotinoids, such as imidacloprid, thiamethoxam and clothianidin, have been found by  a growing body of scientific literature  to be linked to the CCD phenomenon and  pollinator decline in general. While science has become increasingly clear that these  pesticides  play a critical role in contributing to  the ongoing decline of bee health, this is one of the first to look at how these chemicals specifically effect the fertility of male honeybees. In the study, scientists randomly assigned honeybee colonies consisting of drones […]

(Beyond Pesticides, July 26, 2016)  Health Canada’s Pest Management Regulatory Agency (PMRA) announced this week it will cancel certain  formulations  of boric acid-based pesticides. The announcement reflects the latest science showing that certain products, such as those in dust formulations or open baits, put residents at inhalation and ingestion exposure risk, respectively, to the naturally occurring element  boron and borate compounds. PRMA’s decision  is part of the Health Canada’s registration review of boric acid, which, like that of the U.S. Environmental Protection Agency (EPA), is conducted every 15 years. PRMA is cancelling the following uses of boric acid and similar compounds All domestic dust formulation products All domestic granular formulation products Domestic solution formulation products, with the exception of enclosed bait stations and spot treatment with gel formulations For other uses, PRMA has amended label requirements to better protect handlers and users of the pesticide. For example, the agency will update label directions to specify that boron products can only be applied to areas inaccessible to children and pets. Jane Philpott, Minister of Health in Canada said in a press release, “even natural ingredients like boric acid can pose a risk to Canadians. That’s why Health Canada looks at all […]

(Beyond Pesticides July 1, 2016) Lawmakers in France approved plans to totally ban neonicotinoid pesticides by 2018, based on their link  to declining populations of pollinators, specifically bees. This new restriction would go above and beyond current European Union (EU) restrictions on neonicotinoids, which limit the use of neonicotinoids, but do not ban them. The outright ban on neonicotinoid pesticides in France was adopted by a narrow majority of the  country’s  National Assembly, as part of a bill on biodiversity. While the bill must still gain the approval of the French Senate, which rejected it in a previous reading, passage by the Assembly is significant, as France becomes the first country to join state and local movements to eliminate the use of these toxic chemicals. Neonicotinoids have been found by  a growing body of scientific literature  to be linked to honey bee and other pollinator declines. In light of these findings, in 2013 the European Commission  voted to suspend  the use of neonicotinoid pesticides for two years. The ban came several months after the European Food Safety Authority (EFSA)  released a report  identifying “high acute risk” to honey bees from uses of certain neonicotinoid chemicals.   Along with recent reports […]

(Beyond Pesticides, June 29, 2016) A new report published by Regeneration Vermont finds that herbicide and chemical fertilizer use on Vermont dairy farms nearly doubled from 2002 to 2012, increasing from 1.54 to 3.01 pounds of herbicide per acre, respectively. The report, Vermont’s GMO Legacy: Pesticides, Polluted Water & Climate Destruction, by Will Allen, Ph.D. of Regeneration Vermont and Cedar Circle Farm, focuses on the failed promises of genetically engineered (GE, or GMO) crops to reduce chemical inputs required for crop production. While Vermont leads the nation on the GE labeling front, with its  law set to go into effect on July 1, the report, which highlights the flawed exemption on dairy and meat products, is a sobering reminder that this is only a part of the solution to the effects of GE crops and chemical-intensive agriculture. “While the law will force mainstream food corporations to label GMOs in products like Cheetos and Spaghetti-os before coming into the state, it turns a blind eye to the GMO-derived dairy that is the primary ingredient in, for example, Ben & Jerry’s ice cream and Cabot’s cheddar cheese,” says Dr. Allen. “This is about more than the consumer’s right to know. It’s also […]

(Beyond Pesticides, June 28, 2016) In an effort to block the impending implementation of Vermont’s genetically engineered (GE) food labeling law, Senators Debbie Stabenow (D-MO) and Pat Roberts (R-KS) have struck a deal aimed at continuing to keep consumers in the dark about the ingredients in the food they eat. Vermont’s law, signed on May 8, 2014 by Governor Peter Shumlin (D), is set to go into effect on July 1, 2016. After the state defeated a legal challenge brought by the Grocery Manufacturers of American and other industrial food companies, opponents pivoted their efforts to Congress, where they pushed for the so-called DARK (Denying Americans the Right to Know) Act, which would have codified a voluntary labeling system nationwide and preempted Vermont’s law. The DARK Act was passed through the House, yet failed to secure enough votes in the Senate. Despite Senator Stabenow voting against the DARK Act earlier this year, she has now reached a DARK deal that, in effect, would continue to deny Americans important information about the presence of genetically engineered ingredients in the food we eat. While proponents this DARK deal say it will require a mandatory national labeling scheme, the Senate bill includes no […]

(Beyond Pesticides, May 27, 2016) — Thanks to the hard work and efforts of beekeepers, environmental groups, scientists, legislators and activists, Maryland is the first state to pass legislation through its General Assembly that restricts consumers from using neonicotinoids, a pollinator-toxic pesticide. Earlier this month, the state of Connecticut also passed far-reaching legislation aimed at protecting pollinator populations from these toxic chemicals. The Maryland Pollinator Protection Act (Senate Bill 198/House Bill 211) will become law without the Governor’s signature. Supporters had feared a veto from the executive office, but as a result of overwhelming pressure from beekeepers and activists, Governor Larry Hogan (R) allowed the bill to come into law. Under the Act, consumers will not be permitted to buy pesticides that contain neonicotinoids starting in 2018. Certified pesticide applicators, farmers and veterinarians will be still be allowed to use neonicotinoids. Connecticut’s bill also restricts consumer use of neonicotinoids. In addition, it requires the creation of pollinator habitat on state lands, and begins to address the use of these chemicals in agriculture by developing best practices on neonicotinoid coated seeds, and model pollinator habitat in farm preservation programs. As Maryland’s bill made its way through the legislature, an amendment was […]

(Beyond Pesticides, May 10, 2016) Following an apparent accidental release of documents relating to the safety of the herbicide glyphosate, late last month the U.S. Environmental Protection Agency (EPA) also released and then retracted a preliminary ecological risk assessment of another toxic herbicide, atrazine. Under federal law, every pesticide registered in the United States is required to undergo a 15-year registration review to analyze human health and environmental impacts and determine whether the chemical’s use should continue another 15 years. The last decade and a half have seen plethora of studies underscoring that atrazine is harmful to human health, and poses unreasonable adverse risks to ecological health, despite attempts by its major manufacturer, Syngenta, to silence and discredit its critics. EPA’s preliminary ecological risk assessment finds that for current uses at prescribed label rates, atrazine may pose a chronic risk to fish, amphibians, and aquatic vertebrate animals. Where use is heavy, the agency indicates that chronic exposure through built-up concentrations in waterways is likely to adversely impact aquatic plant communities.  Levels of concern, a wonky equation that EPA produces to measure risk, were exceeded for birds by 22x, fish by 62x, and mammals by 198x. Even reduced label rates were […]

(Beyond Pesticides, March 30, 2016) European researchers found  over 50 different types of pesticides in honey bees while  investigating more than 70 honey bee poisoning incidents. Their study, which detected neonicotinoids, pyrethroids, fipronil, and others, highlights the large number of toxic pesticides to which bees are exposed in the environment from agricultural fields to  home gardens. The study results add to the body of knowledge connecting bee poisoning to pesticide exposure. The study, which is a multi-residue analysis to determine pesticides in honey bees   from poisoning incidents, was published in the Journal of Chromatography by a team of researchers from the National Veterinary Research Institute in Poland.   57 pesticides were found in 73 samples of poisoned honey bees, with four pesticides on average, and up to 13 determined simultaneously in a honey bee sample. The compounds detected include 21 insecticides and their metabolites, 20 fungicides, 12 herbicides, 2 acaricides and 2 veterinary medicinal products metabolites.  Among them, metabolites of imidacloprid, thiacloprid, fipronil, methiocarb and amitraz were found. Chlorpyrifos, clothianidin, dimethoate, and tebuconazole were most frequently detected. Of the herbicides detected only MCPA, 2,4-D and prosulfocarb were determined more than once. The authors believe that the study  results contribute […]

(Beyond Pesticides, February 3, 2016) Speaking to The Guardian, a leading Kenyan entomologist warns that spraying pesticides will fail to deal with the Zika virus. Just recently the World Health Organization (WHO) declared the virus a public health emergency over growing concerns that the virus is linked with microcephaly. Aerial and ground applications of pesticides have long been used for mosquito control, but many believe that these methods fail to sufficiently control mosquito populations, promote resistance and kill other species that would have acted as a natural predator to mosquitoes. Dino Martins, PhD, a Kenyan entomologist in an interview with The Guardian said that while pesticides can reduce the population of  flying adult mosquitoes that transmit the virus, they will fail to deal with the epidemic that threatens to become a global pandemic, and warns that spraying landscapes is extremely dangerous.  “It is a quick fix but you pay for it. You kill other species that would have predated on the mosquitoes. You also create a mosaic of sprayed and unsprayed low densities of chemicals that fosters the rapid evolution of resistance.” Mosquitoes have very short life cycle (a week or less), increasing the probability that each succeeding generation is […]
