(Beyond Pesticides, March 7, 2017) Another study, published by a team of French scientists in the journal Occupational and Environmental Medicine, links childhood behavioral problems to pyrethroid insecticide exposure. Synthetic pyrethroids are a class of insecticides that have increased in use over the past decade due to assumptions that they pose fewer risks to human health than older pesticide chemistries, such as organophosphates. However, this latest study is part of a growing body of research showing that pyrethroids share similar neurocognitive health concerns as these older pesticides. . In this research, scientists investigate the interplay between pyrethroid exposure and behavioral problems through a longitudinal cohort study, which tracks levels of pyrethroid metabolites, or breakdown products, in the urine of mothers beginning between six and 19 gestational weeks and then in their children up through six years of age. Childrenâs behavior is measured through a screening questionnaire known as the Strengths and Difficulties Questionnaire (SDQ). SDQ measures how social a child is (altruism), whether the child has difficulty sharing problems or asking for help (internalizing disorders), as well as how defiant or disruptive a child is (externalizing disorders). The study controlled for a number of confounding factors, such as weight, education, location (rural or […]

(Beyond Pesticides, March 6, 2017) A study published last month by Canadian researchers finds that exposure to the neonicotinoid insecticide imidacloprid at environmentally relevant levels results in slight delays in metamorphosis in the tadpoles of the wood frog. While the authors find that this slight delay is not necessarily a cause for concern from an ecological perspective, sublethal effects of pesticide mixtures and a variety of stressors in the environment play a role in extending juvenile periods in frogs, which can increase mortality and population decline. Because neonicotinoids are so widely use, the authors recommend further research on their impact on declining frog populations. The study, published in Environmental Toxicology and entitled, âSublethal effects on wood frogs chronically exposed to environmentally relevant concentrations of two neonicotinoid insecticides,â looks at the chronic exposure effects of the neonicotinoids imidacloprid and thiamethoxam on the wood frog (Lithobates sylvaticus). The wood frog was chosen because it is native to North America and has a wide distribution across the continent. The researchers exposed tadpoles to environmentally relevant concentrations (1ug/L, 10ug/L and 100ug/L) of the commercial formulation of the neonicotinoids (Admire and Actara). The study finds a significant difference in time for tadpoles to metamorphose. Tadpoles exposed […]

(Beyond Pesticides, March 3, 2017) A new report identifies antibiotic use in conventional plant and animal agriculture as contributing to bacterial resistance to critical life-saving human medicines and the importance of organic agriculture in eliminating antibiotic use. The report, Agricultural Uses of Antibiotics Escalate Bacterial Resistance, published in the latest issue of Pesticides and You, finds that while antibiotic use in animal agriculture is widely acknowledged as harmful, the use of antibiotics in chemical-intensive crop production also pose unnecessary and significant risks. The World Health Organization in 2016 identified bacterial resistance to antibiotics as âone of the biggest threats to global health.â The report notes that the herbicide glyphosate, one of the most widely used pesticides in the U.S., is patented by its manufacturer, Monsanto, for its antibacterial properties. As a result, glyphosate leads as the most  widely used antibiotic in agriculture and around homes, gardens, schools, and communities in the U.S. Other antibiotics used widely in apple and pear production are oxytetracycline and streptomycin, which is also used in the production of peaches, beans, celery, peppers, tomatoes and potatoes. These uses at environmentally relevant levels increase bacterial resistance to important antibiotics in medicine. âResistant bacteria move from farms […]

(Beyond Pesticides, February 27, 2017) Myclobutanil, a systemic fungicide commonly used in agriculture and home gardens, can cause significant damage to the muscles that honey bees use to fly and keep warm during the winter. The results of a study, published this month in the journal Proceedings of the National Academy of Sciences (PNAS) by a group of researchers from the University of Illinois at Urbana-Champaign, underscore the importance of wide-scale education and movement away from the regular use of toxic pesticides. After nearly a decade of unsustainable losses, honey bees and other pollinators continue to suffer declines resulting from the use of toxic pesticides, particularly systemic insecticides called neonicotinoids. Although a substantial body of science implicates neonicotinoids as the most serious chemical threat to pollinators currently, the effects of fungicides and other pesticides on these important animals should not be dismissed as inconsequential. In fact, a 2016 study published by researchers at the University of Maryland found that bee colonies may die off as the number of different pesticide exposures increase. In this recent study, researchers discovered complex interactions between myclobutanil, natural compounds found in flowers, and honey beesâ detoxification system, known as cytochrome 450 enzymes. When foraging on flowers sprayed with […]

(Beyond Pesticides, February 22, 2017) The Pest Management Regulatory Agency (PMRA) of Health Canada, which regulates pesticides in the country, recently proposed changes to regulations under the Canada’s Pest Control Products Act (PCPA) that will curtail the ability of individuals living within the country to import pesticide products that do not meet Canadaâs regulatory standards. Designed to address an existing loophole in the country’s law, the policy seeks to eliminate the practice of purchasing pesticide products from international online retailers that circumvent Canadaâs more stringent pesticide regulations. While U.S. law does not contain a similar loophole, U.S. states that restrict pesticide sale and use more stringently than the federal government face a similar legal quagmre. Current PCPA regulations establish a Personal Use Import Exemption that allows individuals to bring in small quantities of pest control products that are not registered for use in Canada, but do not pose an âunacceptable risk.â According to the Canadian government, the original intent of the exemption was to allow travelers to bring small quantities of pest control products, such as insect repellent, into Canada without âlegally undermining the regulatory regimeâ under PCPA. However, with rise of online marketplaces, such as Amazon, the use of the exemption […]

(Beyond Pesticides, February 13, 2017) A study by the World Wildlife Fund (WWF) and others  attributes the reduced number of overwintering monarch butterflies âa reduction of 27% from last yearâto herbicide use and other factors. The World Wildlife Fund (WWF), in conjunction with U.S. and Mexican environmental groups, has been leading the effort in tracking monarch butterflies. Their recently released 2016-2017 study concluded that the population of monarch butterflies decreased 27 percent from last yearâs population, which had marked an increase from dangerously low levels over the previous three years. Overall, this marks an 80 percent decline in monarch population from the 1990âs. Researchers have estimated that within 20 years the monarch butterfly migration could collapse altogether. The study was conducted in December of 2016 when the colonies of monarchs are expected to be at their peak population in Mexico. Monarch populations are gauged by the area of land they inhabit, rather than counts of butterflies.   Thirteen butterfly colonies were observed, recorded and tracked using geographic information systems software. The researchers found that the butterflies occupied 2.91 hectares of forest, which re presents a 27.43 percent decrease in population compared to the 4.01 hectares of forest they inhabited during the […]

(Beyond Pesticides, February 9, 2017) The failure of the U.S. pesticide regulatory system to protect marijuana users was highlighted as Health Canada announced Tuesday that it would begin conducting random pesticide residue testing of marijuana products to ensure that only registered products are being used in medical marijuana production. This comes on the heels of voluntary recalls in 2016 by two licensed Canadian cannabis producers due to the presence of the prohibited pesticides bifenazate, myclobutanil, and pyrethrins in or on marijuana products. Especially concerning is the detection of myclobutanil, a powerful fungicide that, when heated, converts to the hazardous gas hydrogen cyanide. The detection of these toxic chemicals in medical marijuana products is distressing since many users have compromised immune systems or health conditions that make them more susceptible to toxic chemicals. Moves by several states in the U.S. to curb illegal pesticide use in marijuana contain significant pitfalls and loopholes that allow contaminated cannabis to enter the market, where it threatens public health. Without examination of residues in inhaled, ingested, or absorbed cannabis, the userâs health is not protected by pesticide registration addressing other uses. In addition, environmental impacts associated with growing practices are generally ignored. On January 9th, […]

(Beyond Pesticides, February 8, 2017) As the controversy surrounding the Trump Administration and GOP Congressâs plan for the Environmental Protection Agency (EPA) continues to grow, a nonpartisan group of 447 former EPA employees united to write a strongly-worded letter urging the Senate to block Scott Pruittâs confirmation as EPA Administrator. Citing EPAâs âfundamental obligation to act in the publicâs interest based on current law and the best available science,â the group, whose members served under both Democratic and Republican presidents, calls into question Pruittâs qualifications, given his longstanding record of opposing âlongstanding tenets of U.S. environmental law.â This letter is just the latest in the constantly evolving debate over the need for environmental protection. In the past two weeks, the EPA has been under attack by the Trump Administration and Republican lawmakers who would continue to undermine the environmental protections required for clean water, clean air, and healthy natural resources. Myron Ebell, head of Trumpâs EPA transition team, suggested last week that the agencyâs already understaffed workforce be cut from about 15,000 employees to 5,000, with potentially more cuts to follow. Trump himself then issued an executive order proposing that for every new regulation promulgated, two must be repealed, an […]

(Beyond Pesticides, February 7, 2017) After years of legal battle, the Colorado Court of Appeals last week affirmed a ruling that Colorado rancher, James Hopper, must serve two days in jail and pay a $7,500 fine for spraying pesticides that drifted unto his neighborâs farm in violation of a 2012 court order protecting his neighbors. In 2012, organic farmers Rosemary Bilchak and her husband Gordon MacAlpine, were granted a permanent injunction prohibiting pesticide applications within 150 feet of the property line in order to reduce pesticide drift. Last weekâs decision bolsters a legal precedent that wafting pesticides can constitute a trespass against which adjacent landowners and people with health sensitivities are protected. The legal battle began in 2011 when Mr. Hopper obtained his Colorado pesticide applicatorâs license and applied the adulticide Fyfanon, which contains the organophosphate insecticide malathion, to kill mosquitoes on his property. However, the pesticide drifted onto Ms. Bilchak and Mr. MacAlpineâs organic vegetable farm. In 2012, a District Court Judge ruled that they have a right not to have their property invaded by other people or things, and prohibited Mr. Hopper from fogging for mosquitoes within 150 feet of his neighborâs property or allowing the pesticides to drift, […]

(Beyond Pesticides, February 6, 2017) California Department of Pesticide Regulation (CDPR) rules that allow greater use of the highly toxic fumigant Telone, while decreasing protections for the public, have been challenged in California court. On January 31, attorneys representing Juana Vasquez, a farmworker in Ventura County, along with Californians for Pesticide Reform (CPR) and Pesticide Action Network North America (PANNA), filed suit in the Superior Court of California against the California Department of Pesticide Regulation (CDPR). The suit claims that CDPR failed to follow required public procedures in developing new rules for 1,3-Dicholopropene (1,3-D), which is an active ingredient in the product Telone and has many documented health risks, including cancer and kidney and liver damage. In October 2016, CDPR released new rules that allow the continued use of Telone and decrease protections for public health by permitting increased usage. CDPR and many news outlets reported the rule change as a tightening of the restrictions, but in reality, the new rules increase the previous annual cap from 90,250 pounds to 136,000 pounds per township, a defined area of 6Ă6 miles. These new rules went into effect on January 1, 2017, allowing for 1,3-Dâs continued use in strawberry fields, vineyards, almond […]

(Beyond Pesticides, February 3, 2017) The Ruby Throated Hummingbird is the pollinator of the month for February. Hummingbirds are natureâs most nimble of birds. They are so quick and agile that most of the time all youâll see is a flash of red and green before realizing you just encountered a Ruby Throated Hummingbird. This monthâs pollinator is the most abundant species of hummingbird on the eastern half of North America. They are named after the coloration of ruby red feathers around their throat. Range The Ruby Throated Hummingbird is the most populous hummingbird found east of the Mississippi. They enjoy mild habitats such as pine and deciduous forests, and can also be found zipping around urban and suburban gardens and orchards. Ruby Throated Hummingbirds âwinter,â meaning they migrate to warmer parts of the globe during the colder winter months. They typically spend that time in parts of Central America and southern Mexico, but have been known to travel as far south as Costa Rica and the West Indies, according to Animal Diversity Web. They will often migrate without stopping, traveling distances as great as 1,600 km in one trip.  According to the Encyclopedia of Life, the hummingbird’s mating grounds are typically east of the 100th meridian in the […]

(Beyond Pesticides, February 2, 2017) A commonly used inert pesticide ingredient negatively affects the health of honey bees by making larvae more susceptible to a virus, according to a recently published study in the journal, Nature. One of the authors of the study, Julia Fine, PhD candidate, stated that the findings, âMirror the symptoms observed in hives following almond pollination, when bees are exposed to organosilicone adjuvant residues in pollen, and viral pathogen prevalence is known to increase. In recent years, beekeepers have reported missing, dead and dying brood in their hives following almond pollination, and exposure to agrochemicals, like adjuvants, applied during bloom, has been suggested as a cause.â The study assessed honey bee larval development after exposure to a continuous low dose of Sylgard 309, a surfactant, in their diet. This organosilicone surfactant is commonly used on agricultural crops, including tree fruits, nuts, and grapes. Their results reveal that honey bee exposure to chemical surfactants such as Sylgard 309 led to higher levels of Black Queen Cell Virus and when the bee larvae were exposed to the surfactant and virus simultaneously, âthe effect on their mortality was synergistic rather than additive.â This research comes at a time when […]

(Beyond Pesticides, February 1, 2017) Last week in North Miami, the City Council took a significant step that could reduce pesticide use in the community. The Council adopted an Integrated Pest Management (IPM) policy modeled after a plan developed by San Francisco in the mid-90âs. The plan does not ban pesticides and herbicides, but instead aims to reeducate citizens and county workers on least-toxic pest management strategies with the goal of eliminating toxic pesticide use on city property.  The IPM plan does not address pesticide use on private property, due to state preemption of local authority. With the passage of the North Miamiâs resolution, city operatives will now be asked to give preference to available, safe and effective non-pesticide alternatives and cultural practices. As stated in the resolution’s Integrated Pesticide Management Program Guidelines, the goal of the policy is “to eliminate the application of all Toxicity Category I and Category II pesticide products by January 2018.” On top of eliminating certain pesticide categories, the resolution also calls for staff training and expert consultants, both of which have the potential to help ease the transition in pursuit of the 2018 goal, and priority will be given to efforts to reduce or eliminate pesticide use near […]

(Beyond Pesticides, January 31, 2017) A tentative ruling last week by Fresno County Superior Court Judge Kristi Culver Kapetan moves California closer to listing glyphosate (Roundup) as a carcinogen under the stateâs Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). Monsanto, a leading manufacturer of glyphosate under its Roundup brand, sued California to stop the listing, as it would require cancer warning labels be placed on its end-use product. The company indicates it will challenge the tentative ruling. Californiaâs proposed to list glyphosate as a carcinogen after a 2015 determination of the International Agency for Research on Cancer, a United Nations body under the World Health Organization, that the chemical is a cancer-causing agent for humans based on laboratory studies. Monsanto refutes these claims, and since the determination has worked directly, and through proxy organizations, to discredit and attack IARC, as well as individual scientists that have participated in its decision-making process. Shortly after IARCâs Monograph on glyphosate, the German Federal Institute for Risk Assessment (BfR), a Monsanto-supported group, released a report dismissing glyphosateâs link to cancer. In October of last year, the U.S. House of Representativesâ Committee on Oversight and Government Reform, led by Rep. Jason Chaffetz […]

(Beyond Pesticides, January 27, 2016) Last week, farmers, environmentalists, and conservation groups filed a federal lawsuit that challenges the U.S. Environmental Protection Agency’s (EPA) approval of a new formulation of the toxic herbicide dicamba. The new formulation is called Xtendimax with Vapor Grip Technology, which is claimed to have lower volatility. The petitioners claim that EPA violated its duties under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) in issuing a conditional registration, and that it did not adhere to duties under the Endangered Species Act that require EPA to consult with the U.S. Fish and Wildlife Service to ensure registration would not harm any listed species. The organizations involved in the lawsuit are National Family Farm Coalition, Pesticide Action Network North America, Center for Food Safety, and Center for Biological Diversity, represented by legal counsel from Earthjustice and Center for Food Safety. Dicamba has caused a lot of controversy in the past. In August 2016, farmers in Missouri, Arkansas, and Tennessee confronted widespread crop damage and braced for lower yields as a result of agrichemical giant Monsantoâs botched roll-out of GE soybean and cotton crops. The company, whose current line of glyphosate-tolerant crops are failing to control weeds throughout […]

(Beyond Pesticides, January 23, 2017) Last week, the U.S. Environmental Protection Agency (EPA)  released its final Biological Evaluations of Three Chemicalsâ Impacts on Endangered Species, which finds that chlorpyrifos and malathion likely have detrimental effect on 97 percent of all species listed and protected under the Endangered Species Act (ESA), while diazinon adversely affects 78 percent. According to EPAâs release on the subject, this is the âfirst-ever draft biological evaluations analyzing the nation-wide effectsâ of these registered chemicals on endangered species after decades of widespread use. The evaluations stem from a legal settlement with the Center for Biological Diversity (CBD) in which CBD sued EPA in April 2014 for its failure to comply with ESA, which requires the agency to carry out consultations with federal wildlife agencies while registering pesticides. According to Nathan Donley, Ph.D., a CBD senior scientist, âWeâre now getting a much more complete picture of the risks that pesticides pose to wildlife at the brink of extinction, including birds, frogs, fish and plants. When it comes to pesticides, itâs always best to look before you leap, to understand the risks to people and wildlife before theyâre put into use. The EPA is providing a reasonable assessment of those risks, many of which can be […]

(Beyond Pesticides, January 19, 2017) The U.S. Department of Agriculture (USDA) opened a 60-public comment period January 17 on a controversial proposal to establish a federal research and promotion check-off program that has split the organic community, with many family farmers and small farm operators disagreeing with the larger organic industry groups, represented by the Organic Trade Association (OTA), on the benefits that they will derive from a mandatory payment requirement. The application to USDA for a check-off, originally submitted by OTA in 2015, has drawn sharp division on questions of benefits and cost to farmers. OTA believes that the check-off will generate resources to lift the organic market. This program is different from traditional check-off programs, which promote individual commodities. USDA oversees check-off programs under the Commodity, Promotion, Research and Information Act of 1996. According to OTA, the check-off creates an industry-funded promotion, research, and information program for certified organic products, whose overarching goal is to strengthen the position of certified organic products in the marketplace. OTA says this would be achieved by funding research to benefit the organic industry, improving access to information and data across the organic sector, and educating consumers about the benefits of organic, resulting in increased demand for organic […]

(Beyond Pesticides, January 17, 2017) On January 12, 2017, the U.S. Environmental Protection Agency (EPA) released major risk assessment documents on  pollinator exposure to bee-toxic neonicotinoid insecticides finding no significant risks, despite the large and growing body of science identifying the pesticides’ hazards. In the documents, EPA identifies risks posed to bees by several neonicotinoid insecticides, but suggests that no restriction on uses are imminent. In another decision meant to protect bees from acutely toxic pesticides, the agency is scaling back its original proposal in deference chemical-intensive agricultural interests. EPA’s long awaited pollinator assessments for the neonicotinoids: clothianidin, thiamethoxam, and dinotefuran, much like the 2016 pollinator assessment release for imidacloprid, identifies risks to bees from the agricultural applications (foliar, soil and seed) of these chemicals, including from pesticide drift. Observed effects include decline in worker bees, and subsequent declines in brood and pollen stores in the colony. EPAâs assessments continue to focus on honey bees, with cursory mention of wild, native bees. Once again, the assessments did not consider risks from exposures to contaminated water, guttation droplets, or soil, with EPA stating that, âThe Agency lacks information to understand the relative importance of these other routes of exposures and/or to quantify potential risks […]

(Beyond Pesticides, January 12, 2017) Yesterday marked a monumental event in the fight against pollinator declines, as the rusty patched bumblebee became the first bee species to officially be declared endangered by the U.S. Fish and Wildlife Service (FWS). According to FWS, endangered species designations are made when a species is âin danger of becoming extinct throughout all or a portion of their range.â Tom Melius, Service Midwest Regional Director for FWS, stated in a press release that, when it comes to this determination, â[FWSâs] top priority is to act quickly to prevent extinction of the rusty patched bumble bee. Listing the bee as endangered will help [the agency] mobilize partners and focus resources on finding ways right now to stop the decline.â Listed yesterday in the Federal Register, the ruling will go into effect February 10, 2017. This is a victory for environmental groups who have fought to protect the rusty patched bumble bee from widespread threats, such as habitat loss and pesticide use. According to FWS, the rusty patched bumble bee was once widespread across the United States and parts of Canada, but declined dramatically in the 1990s.  Since then, their populations have dwindled and their overall decline is estimated at 91 […]

(Beyond Pesticides, January 11, 2017) Ultra-low doses of glyphosate formulations fed to rats is linked to an increased likelihood of developing non-alcoholic fatty liver disease (NAFLD), according to a recently published study in the journal Nature. A lead author of the study, Michael Antoniou, PhD, stated that the findings are âvery worrying as they demonstrate for the first time a causative link between an environmentally relevant level of Roundup consumption over the long-term and a serious disease.â The findings point to the growing need to eliminate the widespread use of this herbicide, as it has already been implicated in endocrine disruption, reproductive effects, and kidney and liver damage. The researchers analyzed female rat livers obtained from a previous 2-year study on Roundup toxicity using molecular profiling techniques. These rats were administered Roundup via drinking water at a concentration of 0.1 ppb, which is an allowable level within both the U.S. and the European Union. The molecular analyses conducted by researchers on the internal organs of the rats fed Roundup included testing of liver cell disturbances. Overall, ultra-low dose glyphosate-formulation exposure led to observations of biomarkers also seen in fatty liver disease. These findings have human health implications âsince NAFLD is predicted to be the […]

(Beyond Pesticides, January 10, 2017) Exposure to neonicotinoid (neonic) insecticides leads to a decrease in pollination frequency and fewer social interactions in bumblebees, according to research published by scientists from Harvard University and University of California, Davis. The study, released last year but presented this week at the Society for Integrative and Comparative Biologyâs annual meeting, underscores the need for regulators and policy makers to eliminate use of these chemicals, not only to protect honey bees, but also wild pollinators like the bumblebee. While worker bumblebees (Bombus impatiens) divide their tasks within the colony in a similar manner to honey bees, their nests appear quite different than their more structured cousins. “Bumblebee nests are not the organized, beautiful geometry of the honeybee,” said James Crall, PhD candidate in Harvard’s Department of Organismic and Evolutionary Biology. Instead, “They’re more a hodge-podge of food and larvae in a pile in the middle of the nest space.” For their study, researchers placed four bumblebee colonies in a mesh enclosed area, tagged each bee, and observed them foraging on tomato flowers grown in a pollinator-excluding greenhouse (to ensure bees had freshly-opened flowers for pollination each day). After observing normal behavior, bees within each colony […]

(Beyond Pesticides, January 5, 2017) Winegrowers in the Texas High Plains region are concerned that approval of new herbicides by the U.S. Environmental Protection Agency (EPA) will devastate their profitable industry due to chemical damage from pesticide drift. Wine producers in this region of Texas have witnessed chemical damage to their vineyards that they blame on the toxic herbicides, dicamba and 2,4-D, used on cereal crops and pastures on surrounding agricultural land. A new herbicide formulation containing dicamba, XtendiMax with VaporGrip Technology, was approved by EPA, and the agency has recently proposed to register and expand the use of Enlist Duo, a herbicide that contains 2,4-D. EPAâs final decision on registration of Enlist Duo is expected in early 2017. According to Paul Bonarrigo, owner of Messina Hof Winery in Texas, the âapproval of these formulations will wind up affecting every vineyard up there.â This will have ramifications across Texas, as the wine industry contributed $1.88 billion to the stateâs economy in 2013. Advocates say that the new herbicide formulations present unreasonable adverse risks to humans and the environment in addition to harming the livelihood of farmers. Following on these concerns, Garrett Irwin, owner of Cerro Santo vineyard, stated,âIf we get […]
