(Beyond Pesticides, April 4, 2017) Exposure to commonly used pyrethroid insecticides results in the early onset of puberty in boys, according to a study presented at the 99th meeting of the Endocrine Society in Orlando, Florida this week. Pyrethroids, which exhibit endocrine disrupting properties, have the ability to interfere with the proper regulation of the human body’s hormonal system. This research is the first to investigate not only the association between pyrethroids and accelerated puberty, but also the causal mechanisms involved in the physiological changes taking place within the human body. For the study, Jing Liu, PhD, and colleagues from Zhejuang University in China, analyzed the urine in 463 Chinese boys aged 9 to 16 for the presence of metabolites from the pyrethroid insecticide cypermethrin. Results show that a 10% increase in the metabolite 3-PBA is associated with a roughly 4% increase in luteinizing and follicle-stimulating hormones, which facilitate puberty and sperm production. The author’s note that, “Boys with increased urinary levels of 3-PBA have a significantly increased risk of earlier pubertal onset, in which the odds of being in an advanced pubertal stage are increase by 73% to 110%.” The study, acknowledging the limitation in determining causality, further investigates the […]

(Beyond Pesticides, March 31, 2017) On Wednesday, Scott Pruitt, the new head of the Environmental Protection Agency (EPA), rejected the conclusions of EPA scientists, and independent scientific literature, and reversed a tentative decision from 2015 to revoke food residue tolerances of chlorpyrifos due to the chemical’s neurotoxic impacts. This would have effectively banned chlorpyrifos from agriculture. This decision stemmed from a petition and lawsuit filed by the Natural Resources Defense Council (NRDC) and Pesticide Action Network North America (PANNA)  ten years ago, calling for EPA to revoke all chlorpyrifos tolerances and cancel all registrations. A Federal Appeals court mandated that EPA take final action by March 31, 2017. Mr. Pruitt’s decision leaves the door open for continued neurotoxic dangers for humans, especially children, who have been shown to be especially vulnerable to chlorpyrifos. Chlorpyrifos is part of the organophosphate (OPs) class of pesticides, which were used in World War II as nerve agents. As potent neurotoxicants, organophosphates are extremely harmful to the nervous system, given that they are cholinesterase inhibitors and bind irreversibly to the active site of an enzyme essential for normal nerve impulse transmission. The scientific evidence of neurotoxic dangers associated with chlorpyrifos exposure is extensive and consistent. Epidemiological data also […]

(Beyond Pesticides, March 22, 2017) Today, a coalition of farmers and environmental and public health organizations filed a lawsuit against the Environmental Protection Agency (EPA) for approving agrochemical giant Dow Chemical’s toxic pesticide combo, Enlist Duo, among the newer more highly toxic pesticide mixtures used in genetically engineered (GE) herbicide-tolerant crops. Comprised of glyphosate and 2,4-D (50% of the mixture in the warfare defoliant Agent Orange), Enlist Duo is typically marketed alongside commercial crops like corn, cotton and soybeans that are engineered to withstand pesticide exposure, leading to problems of resistance and driving the evolution of super weeds. This is the third lawsuit challenging EPA approval of Enlist Duo by petitioners, which include Beyond Pesticides, National Family Farm Coalition, Family Farm Defenders, Pesticide Action Network North America, Center for Food Safety, and Center for Biological Diversity, represented jointly by legal counsel from Earthjustice and Center for Food Safety. The lawsuit charges that approval of Enlist Duo “will lead to sharply increased spraying of toxic pesticides, harming farmers, neighboring crops, and wildlife.” Specifically farmers’ health and financial positions stand to be heavily impacted by the approval of Enlist Duo, as increased use will result in increased pesticide drift, an alarming concern especially […]

(Beyond Pesticides, March 14, 2017)  The U.S. Environmental Protection Agency (EPA) is opening an investigation into whether the Hawaii Department of Agriculture (HDOA) and the state Agribusiness Development Corporation (ADC) are discriminating against Native Hawaiians in their administration of the state’s pesticide program. The investigation comes after a number of local community groups, represented by the nonprofit environmental law organization Earthjustice, filed a complaint in September 2016 asking EPA to take action against systemic abuses of Native Hawaiian peoples. Local efforts to protect pesticide-exposed communities have been repeatedly stymied by giant pesticide corporations operating on the island, which filed lawsuits that ultimately struck down local laws. EPA’s investigation will focus on the state’s activity on the islands of Kauai and Moloka’i. “The External Civil Rights Compliance Office will investigate whether in administering the pesticides program and the leasing and licensing of the state land program the HDOA and/or ADC discriminated on the basis of race and/or national origin against farm workers and residents of West Kauai and Molokai, in violation of Title VI of the Civil Rights Act, and EPA’s implementing regulation,” wrote Lilian Dorka, director of EPA’s External Civil Rights Compliance Office(ERCO), in a letter to Earthjustice. Under Title […]

(Beyond Pesticides, March 13, 2017) Nearly 1 in 4 species of native bee is imperiled and at increasing risk of extinction. This, according to a new report from the Center for Biological Diversity (CBD), released earlier this month. The report is the first comprehensive review of the more than 4,000 native bee species in North America and Hawaii, and finds that more than half the species assessed are declining. With native bee decline increasing, advocates say it is imperative that action be taken to reduce toxic pesticide use and restore native habitats lost to chemical-intensive agriculture, urbanization, and climate change. The new analysis, Pollinators in Peril: A systematic status review of North American and Hawaiian native bees, reveals that more than 700 species are in trouble from a range of serious threats, including severe habitat loss and escalating  pesticide use. Key findings include: (1) among native bee species with sufficient data to assess (1,437), more than half (749) are declining; (2) nearly 1 in 4 (347 native bee species) is imperiled and at increasing risk of extinction; (3) many of the bee species lacking sufficient data are also likely declining or at risk of extinction, highlighting the urgent need for additional […]

(Beyond Pesticides, March 10, 2017) A French study published last week has found that higher pesticide use does not mean larger profits, demonstrating that farmers can reduce their usage of pesticides without worrying about their profits being affected, in most cases. Similar studies have shown that organic and conventional yields are comparable, supporting the case for farmers to transition from high pesticide use to healthier, safer, and more profitable alternatives. The study, led by Martin Lechenet, a PhD student with the French National Institute for Agricultural Research, looked at data from 946 French farms, including yields, pesticide application rates, soil characteristics, and local climate conditions. The researchers then used a model to focus on the relationship between pesticide application rates and productivity or profitability. They found that, in 77% of the farms, higher pesticide use was not linked to a higher profit. The researchers then estimated that pesticide use could be reduced by 42% without any negative effects on current profit levels in 59% of farms in their national network. According to the researchers, their results demonstrate the ability to reduce pesticide usage for most farmers in current production situations. In addition, other studies support the finding that farmers do not have […]

(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, “Sublethal effects on wood frogs chronically exposed to environmentally relevant concentrations of two neonicotinoid insecticides,” 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, February 27, 2017)  Texas has been dealing with a feral hog issue for many years, however recently Texas Agriculture Commissioner Sid Miller approved the use of a toxic rodenticide in an effort to control feral hog populations, a decision hunters and trappers oppose because the pesticide will poison prey and wreak havoc on ecosystems where the hogs live. The estimated population of the feral hog population is about 1.5 million in the state of Texas, where they can cause extensive damage to property, crops, and native wildlife. Wild hogs have been considered to be one of the most destructive invasive species in the U.S. The feral hog population, close to six million, span 39 states and four Canadian provinces. Commissioner Miller, in announcing the widespread use of toxic pesticide referred to the problem as the “feral hog apocalypse.” Damage caused by wild hogs has been estimated to reach well into the millions. Smithsonian Magazine has reported the annual damage caused by feral hog populations to be around $400 million. The Texas Parks and Wildlife website states that hogs are opportunistic omnivores.  Feral hogs enjoy eating domestic agricultural crops, such as corn, soybeans, peanuts, potatoes, watermelons and cantaloupe. They can cause […]

(Beyond Pesticides, February 23, 2017) Male pesticide applicators who experienced a pesticide spill or another related accident are more likely to harbor changes in their DNA associated with an increased risk of prostate cancer, according to a recent paper published in the journal, Environmental and Molecular Mutagenesis. While the relationship between pesticide exposure and prostate cancer is not new, this study adds to the growing body of evidence that high exposure to specific pesticides may lead to the development of prostate and other cancers. The analysis finds that after experiencing one of these exposure events, men are more likely to have higher DNA methylation of a gene linked with an increased risk of developing prostate cancer. DNA methylation is a form of gene regulation that, if disturbed, can result in gene expression changes that can cause cancer. The researchers used data from the ongoing Agricultural Health Study (AHS), which is a long-term cohort study evaluating cancer and other health outcomes of pesticides applicators and their spouses in North Carolina and Iowa. This paper, High pesticide exposure events and DNA methylation among pesticide applicators in the agricultural health study, analyzed a sample size of 596 male pesticide applicators who underwent three phases of […]

(Beyond Pesticides, February 21, 2016) The Agriculture Committee in the U.S. House of Representatives approved a bill last week that will eliminate protections from toxic pesticides for the nation’s waterways. The bill now moves on to the full House for a vote and the public has an opportunity to let Representatives hear the concerns about weakening local protection of waterways from toxic pesticides. HR 953, The Reducing Regulatory Burdens Act (code for the sponsors and supporters as legislation to eliminate environmental protection of water quality), is the committee’s latest effort in a multi-year string of attempts to rollback common sense protections for the public waterways all Americans use for swimming, fishing, and other forms of recreation. The bill would repeal the Clean Water Act requirement that those who apply pesticides to waterways, with an exemption for farm use pesticides not directly deposited into waterways, obtain a National Pollutant Discharge Elimination System (NPDES) permit. Last May, at the height of fears over the Zika epidemic, the same Committee ushered through the same bill under another misleading name, The Zika Vector Control Act. Pensive lawmakers and the public saw through the ruse, and the bill was defeated. But, like previous iterations, including the 2015 Sensible Environmental […]

(Beyond Pesticides, February 16, 2017) On Tuesday, the Natural Resources Defense Council (NRDC) sued the Trump administration for reversing a February 10 rule, published in the Federal Register, that designated the Rusty Patched Bumblebee an endangered species under the Endangered Species Act (ESA). The reversal  of the endangered species listing establishes a new review period until March 21. As to their reasoning for such a sudden change, the U.S. Fish and Wildlife Service (FWS) cited the White House memo instructing federal agencies to postpone the effective date of any regulations that had been published in the Federal Register, but not yet in effect. As discussed several days ago, the order by the Trump administration means that despite FWS’ determination that without federal action the species will likely become endangered, the Trump administration has 60 days to evaluate the decision for the purpose of “reviewing questions of fact, law, and policy.” The lawsuit, filed in the U.S. District Court for the Southern District of New York, argues that FWS violated the notice and comment requirements of public rulemaking for the delay on the bumblebee listing. In the lawsuit, NRDC states that, “Without valid explanation, opportunity for public input, or other legally required process, FWS […]

(Beyond Pesticides, February 14, 2017) Less than one month after the Rusty Patched Bumblebee’s listing as ‘threatened’ under the Endangered Species Act (ESA) by the U.S. Fish and Wildlife Service (FWS), the Trump Administration has reversed the order. On his first day in office, President Trump issued a memo instructing federal agencies to postpone the effective date of any regulations that had been published in the Federal Register, but not yet in effect. This order means that despite FWS’ determination that without federal action the species will likely become endangered, the Trump administration has 60 days to evaluate the decision for the purpose of “reviewing questions of fact, law, and policy.” Advocates for the imperiled species are urging the administration to allow the Rusty Patched Bumblebee to officially become the first bumblebee federally recognized under ESA. Although the Rusty Patched was once widespread throughout the United States and parts of Canada, it declined dramatically in the 1990’s, and now their populations are estimated to be less than 10% of what they once were.  On its website, FWS lists a number of threats to the Rusty Patched, including pesticides, habitat loss, disease, climate change, and intensive farming practices. Insecticides known as neonicotinoids, […]

(Beyond Pesticides, February 13, 2017)  A study by the World Wildlife Fund (WWF) and others  attributes the reduced number of overwintering monarch butterflies –a reduction of 27% from last year—to 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 year’s 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 1990’s.  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 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 neighbor’s 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 week’s 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 applicator’s 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. MacAlpine’s 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 neighbor’s 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 6×6 miles. These new rules went into effect on January 1, 2017, allowing for 1,3-D’s continued use in strawberry fields, vineyards, almond […]

(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-90’s. 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 Miami’s 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 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 Monsanto’s 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 26, 2017) In a startling move that puts independent science at odds with government, the Trump administration’s U.S. Environmental Protection Agency (EPA) transition team stated on Wednesday that scientists will now face “an unspecified vetting process before sharing their work outside the agency.” However, this kind of review is at odds with EPA’s own scientific integrity policy, which “prohibits all EPA employees, including scientists, managers, and other Agency leadership, from suppressing, altering, or otherwise impeding the timely release of scientific findings or conclusions.” This comes on the heels of an announcement by the administration several days ago issuing scientific grant and hiring freezes at EPA nationwide, along with effectively banning science communications through social media platforms. According to ProPublica, an EPA employee stated that, “Hiring freezes happen, but freezes on grants and contracts seemed extraordinary.” These grants are used for financial support to complete environmental testing, remediation and environmental improvement projects across the country. Additionally, on Friday, January 20, after Donald Trump was officially sworn in, he ordered a freeze on all pending regulations from the Obama administration. This included the listing of the rusty patched bumblebee as endangered by the U.S. Fish and Wildlife Service, which had been set […]

(Beyond Pesticides, January 24, 2017) An analysis conducted by scientists at the University of St. Andrews in Scotland is calling into question the conclusions reached in a study conducted by multinational chemical company Syngenta, which indicated that honey bees were not at risk from the widely used neonicotinoid insecticide thiamethoxam. The challenge to the Pilling et al 2013 study is important because while many experiments have been performed in the lab or semi-lab environment, this study was a field experiment developed to test pollinator exposure under normal agricultural conditions. The conclusions of such real-world experiments are weighed more heavily by regulators when making safety and use determinations. St. Andrews’ scientists focus in on the Pilling et al claim that because its study did not have high levels of replication, that it would have been misleading to perform formal statistical analysis. They respond that this would indeed be the case if Pilling et al had intended on finding statistical significance and concluded that there was no effect based on those tests. However, Syngenta’s scientists instead simply graphed average values over time based on their measurements (measurements such as number of bees in a hive, hive weight, number of brood, etc.), and compared […]

(Beyond Pesticides, January 23, 2017) Last week, the U.S. Environmental Protection Agency (EPA)  released its final Biological Evaluations of Three Chemicals’ 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 EPA’s release on the subject, this is the “first-ever draft biological evaluations analyzing the nation-wide effects” 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, “We’re 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, it’s always best to look before you leap, to understand the risks to people and wildlife before they’re put into use. The EPA is providing a reasonable assessment of those risks, many of which can be […]

(Beyond Pesticides, January 18, 2017) Despite science affirming its hazards, the U.S. Environmental Protection Agency (EPA) has expanded the registration of the toxic herbicide mixture, Enlist Duo, which contains 2,4-D and glyphosate, for use on genetically engineered (GE) cotton and extended its use on GE corn, soybean, and cotton from 15 to 34 states. This approval late last week comes at a time when widespread chemical use is threatening public health and the environment and weed resistance continues to grow, threatening farmers’ productivity and profitability. Over 600 public comments were submitted to EPA on this issue, with many comments vehemently opposing the current uses and the proposed expansion of uses. In its decision, EPA stated that Enlist Duo “meets the safety standard for the public, agricultural workers, and non-target plants and animal species.” However, as Beyond Pesticides stated in comments to the agency, EPA has not fully considered all the environmental costs, including the cost of tackling increased 2,4-D resistant weeds, crop and non-target damages from uncontrolled drift, as well as unanswered questions regarding synergistic chemical effects in non-plant species. Advocates predict weed resistance to Enlist Duo and have urged EPA to reject its continued use and incentive sustainable organic practices. Additionally, […]

(Beyond Pesticides, January 13, 2016) Just prior to the U.S. Environmental Protection Agency (EPA) announcement on January 12 that several neonicotinoid insecticides “do not pose significant risks to bee colonies,” the preprint version of a new review of neonics identified the range of lethal and sublethal effects of the chemicals on non-target organisms.  The review, The Environmental Risks of Neonicotinoid Pesticides: a review of the evidence post-2013, authored by Dave Goulson, PhD, and Thomas James Wood, a PhD candidate, concludes that studies published since the 2013 European Food Safety (EFSA) published risk assessments show even greater risks. The EFSA assessment, which led to a moratorium on neonicotinoid uses, found that certain neonics on specific flowering crops pose a high risk to bees. With reference to the 2013 EFSA risk assessment conclusions as their baseline, the researchers summarize the difference in risk for certain categories, including: “Risk of exposure from and uptake of neonicotinoids in non-crop plants. Uptake of neonicotinoids by non-target plants was considered likely to be negligible, though a data gap was identified. Many studies have since been published demonstrating extensive uptake of neonicotinoids and their presence in the pollen, nectar and foliage of wild plants. Exposure from non-target plants clearly represents a Greater […]
