(Beyond Pesticides, April, 30, 2019) According to the latest blog post from pesticide industry propagandist Henry I Miller, the pollinator crisis either a) is not occurring; b) is not a problem; or, c) caused by varroa mites, pathogens, and habitat loss. Notwithstanding outlandish assertions that there is no pollinator crisis, new research is further undermining the long-held industry claim that it is mites and disease alone, and not pesticides that are harming pollinator populations. Published in the journal Scientific Reports by a team of Canadian scientists, this research finds that realistic exposure to neonicotinoid insecticides impairs honey bees ability to groom mites off of their bodies and increases infection with a disease known as deformed wing virus (DWV). “When bee colonies began to collapse years ago, it became clear there wasn’t just one factor involved, so we were interested in whether there was an interaction between two of the main stressors that affect bees: varroa mites and a neurotoxic insecticide, clothianidin,” said Nuria Morfin Ramirez, PhD, at the University of Guelph, Canada. Dr. Ramirez and her team exposed honey bees to a range of different concentrations (low, medium, high) of the neonicotinoid clothianidin, with some bees receiving combined stressors of […]

(Beyond Pesticides, April 25, 2019) As reported by Mother Jones, the New York Times (NYT) published, on April 6, a distressing report about a deadly fungus that has been advancing steadily across the world during the past five years. Candida auris is an emerging fungal pathogen that threatens those with compromised or immature immune systems, such as infants, the elderly, people taking steroids for autoimmune disorders, diabetics, those undergoing chemotherapy, and even smokers. Nearly half of those who contract a C. auris infection die within 90 days. One of the factors making this fungus so deadly is that it has developed resistance to existing antifungal medicines, with 90% of infections resistant to one drug, and 30% to two or more. As is true for resistant bacteria, culprits in C. auris’s development of resistance may be the overuse of antifungal medications in health care and overreliance on fungicides in agriculture. The Centers for Disease Control and Prevention (CDC) has added C. auris to its list of pathogens considered “urgent threats.” It is an “emerging fungal pathogen,” meaning that the incidence of infection has been increasing across multiple countries since it was first recognized in 2009 in Japan (although a different strain had […]

(Beyond Pesticides, April 17, 2019)  A neurotoxic pesticide labeled “bee-safe” has been found to be harmful to bees, according to a new study. Flupyradifurone (FPF), the subject of the study, is a novel chemical that was hastily registered in the wake of public awareness about the impact of neonicotinoid insecticides on bees. A systemic insecticide and a nicotinic acetylcholine receptor (nAChR) agonist, it functions in the same way as a neonicotinoid, though it is in the butanolide family. “Lethal and sublethal synergistic effects of a new systemic pesticide, flupyradifurone (Sivanto®), on honeybees,” not only debunks the myth that FPF is safe on its own, it also delves into the FPF’s synergistic effects with a commonly used fungicide propiconazole (PRO). PRO, on its own, has no impact on bee mortality. A rarely studied realm of pesticides, the study defines a synergistic effect as, “when combined exposure to two factors results in an effect that is significantly greater than the sum of individual effects.” Researchers manipulated six healthy honey bee (Apis mellifera ligutica) colonies and observed the impact of varying amounts of pesticide exposure, including both individual and synergistic effects, on behavior and mortality. They recorded data over seasons and between worker […]

(Beyond Pesticides, April 8, 2019) Officials in Europe and the U.S. focus on banning problem pesticides, raising concerns about their replacements in the face of pesticide-intensive management strategies, while organic advocates call for a systems change in land management. In reference to widespread community bans of Roundup/glyphosate, Cary Gillam, author of Whitewash, told last year’s Beyond Pesticides’ Forum, “Glyphosate is the poster child for the bigger pesticide problem.” She continues, “If it goes away tomorrow, we are not okay.” Because of this, Beyond Pesticides has strategically sought to transform our country’s approach to pest management, both agricultural and residential/structural, by eliminating a reliance on pesticides and advancing organic management practices that do not rely on toxic inputs. This Daily News Blog post offers updates on progress in the European Union (EU), in the U.S. Congress, and in communities and sates nationwide. The EU is poised to ban clorothalanil, a commonly used — and highly toxic — organochlorine fungicide, The Guardian reported, in mid-to-late May 2019. After a review by the European Food Safety Authority (EFSA), EU states voted to approve a ban. EFSA identified as a chief safety concern the possibility that breakdown products (metabolites) of the compound may cause damage […]

(Beyond Pesticides, April 5, 2019) Beyond Pesticides’ 37th National Pesticide Forum, Organic Strategies for Community Environmental Health, begins today at the New York Academy of Medicine, and continues until tomorrow night, where the New York City premiere of the new documentary Ground War will take place with special guest Lee Johnson—who successfully sued Monsanto after linking his cancer to exposure to the weed killer glyphosate. (Tickets are $10 and available through Ticketmaster until sold out, please sign up/log in to a Ticketmaster account to purchase). The two-day conference is convened by Beyond Pesticides in collaboration with the Children’s Environmental Health Center of the Icahn School of Medicine at Mount Sinai, and 24 local cosponsoring organizations. The conference begins at 4:30 pm on Friday April 5, followed by a reception and evening session. Saturday includes breakfast and runs from 8:30 am until 5:30 pm. The Ground War screening, to be held at Florence Gould Hall (55 E. 59th Street), starts at 7:30 pm and concludes with a panel discussion featuring advocates and California Groundskeeper Dewayne Lee Johnson. The Forum provides a unique place to network with advocates, scientists, practitioners, policy makers, and other experts on the cutting edge of the pesticide […]

(Beyond Pesticides, April 4, 2019)  Following on its verdict that the herbicide Roundup caused plaintiff Edwin Hardeman’s  non-Hodgkin lymphoma (NHL), the jury on March 27 issued an award of $80 million—$5 million in compensatory damages and $75 million in punitive damages—for improper labeling and negligence on the part of the manufacturer and defendant, Monsanto. The trial, the first federal Roundup cancer trial, marks the first of a multidistrict litigation against Monsanto, with more than 1,600 similar lawsuits pending in San Francisco’s federal court. The jury’s second verdict affirmed Mr. Hardeman’s allegations that Roundup’s design is defective and lacks sufficient warnings, and that Monsanto was negligent by not using reasonable care to warn about Roundup’s NHL risk. The Edwin Hardeman v. Monsanto Co. jury verdict marks the second multi-million dollar award to be granted in a landmark case against Bayer/Monsanto within the past year. Last August in San Francisco Superior Court, California groundskeeper Dewayne “Lee” Johnson was awarded $39 million in compensatory damages, and $250 million in punitive damages in the first case that linked his NHL to Monsanto’s glyphosate/Roundup. In October, the judge in the case upheld the verdict, but reduced the award to $78 million. Mr. Hardeman is represented by […]

(Beyond Pesticides, March 25, 2019) EPA is using a regulatory loophole – the “treated articles exemption” – to allow systemic insecticides to be used in mass quantities, without regulating or labeling them as required under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). EPA does not currently assess adverse effects on the environment and public health caused by widespread use of neonicotinoid insecticides delivered through seeds coated with the insecticides, resulting in widespread exposure to one of the most environmentally damaging classes of chemicals on the market. Tell your Congressional delegation that EPA must fully regulate treated seeds to protect the environment and public health. Pesticide-coated seeds are now ubiquitous, yet their far-reaching impacts on wildlife and human health continue to go unregulated. The introduction and spread of seed-delivered pesticides to major field crops, beginning around 2003, caused a massive increase in total neonicotinoid use nationwide. As of 2011, 34 to 44% of soybeans and 79 to 100% of maize acres were planted with coated seeds, accounting for an astounding 35-fold increase in nationwide neonicotinoid use from baseline rates prior to 2003 (Douglas and Tooker, 2015). Alarmingly, because the national pesticide survey conducted by the National Agricultural Statistics Service fails to […]

(Beyond Pesticides, March 22, 2019) A two-year study, published March 14,  finds that field-relevant contamination with the neonicotinoid insecticide imidacloprid causes reduced body weight and metabolism in white-tailed deer, and – in fawns – mortality. Remarkably, researchers uncovered imidacloprid levels in free-ranging deer a full 3.5 times higher, on average, than the levels in the animals treated in their experiment. These new findings add to the mounting evidence of the hazards posed by current patterns of neonicotinoid use, while evidence of benefits remains sparse. The study, published in Nature Scientific Reports, includes two years of data on the physiological and behavioral outcomes of imidacloprid contamination in 80 white-tailed deer housed in a South Dakota State University captive research facility. Notably, researchers were unable to entirely control imidacloprid levels in untreated deer, most likely due to background contamination from corn- and soy-based feed, and surrounding vegetation infiltrated by runoff from nearby agricultural fields. This background contamination altered, but did not compromise, the analysis. Researchers found that imidacloprid levels detected in the spleens of treated and control animals were significantly predictive of reduced thyroid hormone levels, shorter jawbones, lower activity levels, and higher fawn mortality. Lead authors Elise Berheim, Jonathan Jenks, PhD, […]

(Beyond Pesticides, March 19, 2019) Research is beginning to explain how systemic neonicotinoid insecticides affect often overlooked species of ground nesting bees. While much of the current scientific literature has focused on the impacts of pesticides to bumblebees and honey bees, a study, Chronic contact with realistic soil concentrations of imidacloprid affects the mass, immature development speed, and adult longevity of solitary bees, recently published in Scientific Reports, confirms that wild, soil-dwelling bees are at similar risk. As policy makers consider ways to protect pollinators, this research finds that uncontaminated soil is an important aspect of ensuring the health of wild, native bees. “This is an important piece of work because it’s one of the first studies to look at realistic concentrations of pesticides that you would find in the soil as a route of exposure for bees,” said Nick Anderson, co-author of the study. “It’s a very under-explored route, especially for some of the more solitary species that nest in the ground.” In order to study the impact of neonicotinoids on ground nesting bees, researchers used orchard mason bees and leafcutter bees as proxies, as they are easier to gather and rear in the lab, and have a similar ecology […]

(Beyond Pesticides, March 11, 2019)  We must stop the expanded commercialization of genetically engineered pesticides. The failure of the U.S. Environmental Protection Agency (EPA) to fully evaluate environmental impacts of gene-manipulating pesticides raises serious concerns in light of the agency’s ongoing failure to predict ecological effects of pesticides, such as the dramatic decline of pollinators. With the release of a 2019 peer-reviewed scientific article, Environmental Fate of RNA Interference Pesticides: Adsorption and Degradation of Double-Stranded RNA Molecules in Agricultural Soils, on the potential impact on soil and non-target microorganisms in soil, the study’s co-author, Kimberly Parker, PhD, remarked, “The ecological risk assessment of these emerging pesticides necessitates an understanding of the fate of dsRNA [double stranded RNA] molecules in receiving environments, among which agricultural soils are most important.” This technology, given that it is systemic to the plant and leaves traces in the soil, can cause widespread indiscriminate poisoning—as has been seen with bees, butterflies, birds, and the larger catastrophic decline of insect populations. Tell your members of Congress that the ecological effects of RNAi gene-manipulating pesticides raise serious questions—they have not been fully studied by EPA and, until they are, the agency should issue a moratorium on their release. Previously, […]

(Beyond Pesticides, March 7, 2019) A publication in the journal Environmental Health Perspectives highlights findings from a recent study showing that environmental concentrations of the neonicotinoid insecticides thiacloprid and imidacloprid increase expression of a gene linked to hormone-dependent breast cancer. Authors of the featured study uncovered a pathway through which neonicotinoids stimulate excess estrogen production, known to occur during the development of progressive hormone-dependent breast cancer. In the words of the authors, “Our findings highlight the need for further research to assess the potential impacts of low-dose and chronic exposure to neonicotinoids on endocrine processes affecting women’s health.” The study, published in Environmental Health Perspectives in April 2018 by researchers at the University of Quebec, is not the first to point to a potential link between neonicotinoid exposure and breast cancer. A 2015 study by the same research group revealed that the neonicotinoids thiacloprid and thiamethoxam, along with the herbicide atrazine, induce similar effects in breast cancer cells. In both studies, exposure to neonicotinoids alter promoter activity to induce heightened production of the enzyme aromatase, which is known to stimulate estrogen production and thereby cancer cell proliferation. The recently published study, authored by Silke Schmidt, PhD, brings greater urgency to […]

(Beyond Pesticides, March 4, 2019) Last week, U.S. Representative Earl Blumenauer (D-OR) reintroduced the Saving America’s Pollinators Act (H.R.1337) to cancel specific bee-toxic pesticides and establish a review and cancellation process for all pesticides that are potentially harmful to pollinators. The specific pesticides targeted in the bill include the systemic insecticides imidacloprid, clothianidin, thiamethoxam, dinotefuran, acetamiprid, sulfoxaflor, flupyradifurone, and fipronil. The bill also establishes requirements for review of other potentially bee-toxic chemicals by an independent pollinator protection board, and requires annual reports on the health and population status of pollinators. The bill creates a sustainable model for pollinator protection in the face of ongoing obstruction by an increasingly industry-influenced EPA. There are 29 cosponsors to date. The current bill is the fifth version of Saving America’s Pollinators Act (SAPA), which was first introduced by U.S. Representative Conyers (D-MI) in 2013. The newest version differs from previous bills in its bold definition of who should have responsibility for assessing harm to pollinators. SAPA 2019 calls for the establishment of a Pollinator Protection Board, to be composed of expert scientists, beekeepers, farmers, members of environmental organizations and other key stakeholders, nearly all of whom must not have any conflict of interest or affiliation […]

(Beyond Pesticides, February 21, 2019) In 2018, the Environmental Protection Agency (EPA) approved 16.2 million acres of crops to be sprayed with the bee-toxic insecticide sulfoxaflor under an emergency exemption. Sulfoxaflor was used in 18 different states on cotton and sorghum — plants known to attract bees. In response to a lawsuit headed by beekeepers, the EPA reclassified sulfoxaflor in 2016 and, recognizing its toxicity to bees, prohibited use on crops that draw in these pollinators. However, Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) gives the EPA authority to permit temporary emergency use of unapproved pesticides. This loophole is used regularly in response to predictable stressors. “Emergency” use was approved 78 times for sulfoxaflor on sorghum and cotton between 2012-2017. Sulfoxaflor is a systemic insecticide that acts similarly to neonicotinoid pesticides. After application, the chemical is absorbed and distributed throughout the plant, including pollen and nectar. These kinds of chemicals are selective agonists of insects’ nicotinic acetylcholine receptors—they bind to the receptor and cause it to activate. The impact on foraging bees is sublethal, but devastating on a population level. Even at low levels, sulfoxaflor impairs reproduction and reduces bumblebee colony size. Sufloxaflor is functionally identical to […]

(Beyond Pesticides, February 15, 2019) A study, published in January 2019 in the journal Environmental Health, demonstrates that consumption of organic foods reduces significantly the levels of synthetic pesticide residues in the bodies of U.S. children and adults. Pesticide residues are found four times as frequently in conventionally grown food as in organically produced foodstuffs. Although the number of subjects in this study was relatively small, the results point to the importance of organics, and add to the evidence that organic food production and consumption are key to protecting human health. Study subjects comprised members of racially diverse families — from Oakland, Minneapolis, Baltimore, and Atlanta — who did not typically consume an organic diet. Study participants, ages 4 to 52, ate their typical diet of conventionally grown foods for five days; for the following six days, they switched to a certified organic diet (provided by researchers) for consumption at home, work, school, or daycare, including all foods and beverages other than water. Urine samples were gathered prior to the “organic” days, and first thing on the morning after those six days. Fourteen different pesticides and metabolites were present in all participants’ urine in the “pre-organic” analysis; following the organic diet […]

(Beyond Pesticides, February 11, 2019) A new systematic review of insect population studies worldwide reports on “the dreadful state of insect biodiversity in the world, as almost half of the species are rapidly declining and a third are being threatened with extinction.” The study concludes with the dire prediction that insects as a whole will go extinct in the next few decades if patterns of intensive agriculture, in particular pesticide use, continue. The review, published in Biological Conservation, analyzes 73 insect population studies conducted within the past 40 years, filtered to include only those that quantitatively assess all insect species within a taxa over a span of 10 or more years. Researchers Francisco Sánchez-Bayo, PhD and Kris A.G. Wyckhuys, PhD uncover the disturbing truth behind this mass of data: one in every three insect species monitored worldwide is threatened with extinction. Even more concerning is the finding that 41% of insect species worldwide are in decline, outpacing the more well-publicized vertebrate declines by 200%. Only a few species are expanding in range or occupying vacant niches – not nearly enough to compensate for the massive losses. In 8% of the studies in the review, citizen science data is analyzed in […]

(Beyond Pesticides, February 4, 2019)  Although the rusty patched bumblebee was placed on the endangered species list in 2017, the Trump Administration has failed to put in place legally required safeguards for the species. The U.S. Department of the Interior (DOI) must designate locations where additional protections could help restore the endangered bumblebee’s population. Tell Your U.S. Representative and U.S. Senators to Urge U.S. Department of Interior Acting Secretary David Bernhardt to protect the endangered rusty patched bumblebee as required by law. DOI’s failure to comply with requirements under the Endangered Species Act (ESA) is consistent with the Trump Administration’s continued disregard for ongoing pollinator declines and environmental protections in general. Under ESA, DOI is required to determine “critical habitat” that contains physical and biological requirements a listed species needs in order to recover. That area must be designated within one year of placing a species on the endangered list, using best available scientific data. The Trump Administration’s DOI has failed to do so under either former Director Ryan Zinke or Acting Director David Bernhardt. Without determining critical habitat, the administration is in violation of the ESA, and the survival of a critical endangered species is threatened. The rusty patched bumblebee has a […]

(Beyond Pesticides, January 17, 2019) Although the rusty patched bumblebee was placed on the endangered species list in 2017, the Trump Administration has failed to put in place legally required safeguards for the species. As a result, the Natural Resources Defense Council (NRDC) is suing the Administration’s Department of the Interior (DOI) for failing to designate locations where additional protections could help restore the endangered bumblebee’s population. Advocates say DOI’s failure to comply with requirements under the Endangered Species Act (ESA) is consistent with the Trump Administration’s continued disregard for ongoing pollinator declines and environmental protections in general. Under ESA, DOI is required to determine “critical habitat” that contains physical and biological requirements a listed species needs in order to recover. That area must be designated within one year of placing a species on the endangered list, using best available scientific data. But the Trump Administration’s DOI, under both former Director Ryan Zinke and Acting Director David Bernhardt, has failed to do so, in violation of ESA. NRDC’s legal director Rebecca Riley notes that this lack of follow-through “leaves this highly endangered bee’s habitat at risk of destruction and decreases the species’ chance for survival.” The rusty patched bumblebee has […]

(Beyond Pesticides, January 16, 2019) Preliminary counts in California indicate the western monarch butterfly population dropped 86% from 2017 to 2018. The survey is a result of an annual effort by volunteer citizen scientists, organized by the nonprofit organization Xerces Society. If the trend from the initial sample (97 sites) holds true, the population of overwintering butterflies is estimated to be less than 30,000 – 0.05% of its historical size. Full and vetted results will be published in late January. To get an accurate count of monarch populations, volunteers follow a monitoring guide, which recommends beginning a count on a still, cool, and dry morning so that monarchs are still clustered together. Volunteers count a small cluster of monarchs and then extrapolate that number to arrive at a total for the larger cluster they’re observing. Citizen science has been crucial to understanding the decline of monarchs and insects worldwide. As covered by The New York Times, the current “Insect Apocalypse” has largely been documented by volunteers. The dismal numbers recorded this year are potentially disastrous, as the predicted extinction threshold for overwintering western monarchs is a population of 30,000. However this threshold, based on population densities needed for thermoregulation and mating […]

(Beyond Pesticides, January 9, 2019) It is news to approximately no one that pollinators are in trouble worldwide. A series of papers by biologists at the University of Guelph, Ontario, posits that pesticide regulations aimed at protection of honey bees fall far short of the critical task of protecting the multitude of bee species that are important pollinators of human food crops. These recent papers arose from 2017 workshops that involved 40 bee researchers from various universities, and representatives from Canadian, U.S., and European regulatory agencies, and from the agrochemical industry. Beset by shrinking habitat, pathogens, and toxic chemical exposures, bee pollinator populations are at great risk, even as “‘our dependency on insect-pollinated crops is increasing and will continue to do so as the global population rises,’ said [Professor Nigel] Raine, [PhD], [a] co-author of all three papers recently published in the journal Environmental Entomology. . . . Protecting wild pollinators is more important now than ever before. Honeybees alone simply cannot deliver the crop pollination services we need.” There are, in fact, more than 20,000 bee species worldwide, and 3,500–5,000 bee species in North America alone. Although regulators across many countries have focused narrowly on assessing the risk of pesticides to honey bees, many […]

(Beyond Pesticides, January 4, 2019) First, the good news: plaintiffs in a 2013 lawsuit against the Environmental Protection Agency (EPA) can allow themselves a small victory dance. In that suit, plaintiffs made a number of claims related to EPA’s failure to protect pollinators from dangerous pesticides, its poor oversight of the bee-killing pesticides clothianidin and thiamethoxam, and its practice of “conditional registration,” as well as labeling deficiencies. The parties in the suit negotiated a settlement, as directed by a federal judge (see below), that was signed in October 2018 and portends some positive movement in curtailing the use of some toxic pesticides [12 products, each of which contains chlothianidin or thiamathoxam as an active ingredient] that harm pollinators in particular, as well as other organisms and the environment. It also establishes a public process for EPA to consider requiring whole formulations of pesticide products during registration, and redefining EPA’s interpretation of law that allows seeds treated with bee-toxic pesticides to escape regulation as a pesticide. The suit was brought by a number of individual beekeepers and several organizations, including Beyond Pesticides, Center for Food Safety (CFS), Sierra Club, and Center for Environmental Health, and named as defendants Steven Bradbury, then-director of the […]

(Beyond Pesticides, January 3, 2019) Bee-toxic pesticides banned for consumer use by the state of Maryland are still being sold in hardware and garden stores, according to reports from beekeeper and consumer watchdog groups. In 2016, Maryland passed the Pollinator Protection Act, which limited the use of neonicotinoids, insecticides implicated in the global decline of pollinator populations, to only certified applicators. According to spot checks by the Maryland Pesticide Education Network (MPEN) and the Central Maryland Beekeepers Association (CMBA), state enforcement agencies still have a ways to go to ensure retailers are complying with the law. From May to October 2018, six volunteers visited 30 Maryland stores along the Baltimore-Washington corridor to see whether they are complying with the law by removing bee-toxic neonicotinoids from retail consumer sale. Eleven of the 30 stores were not in compliance, ranging from local home and garden stores to national big-box chains. “I’ve taken bottles off the shelf and taken them up to an employee or a manager, and said, ‘You really need to stop selling this stuff — it’s illegal,’” said Steve McDaniel, a master beekeeper in Carroll County to the Bay Journal. The state, for its part, indicates that staffing problems at […]

(Beyond Pesticides, December 14, 2018) The richness, diversity, and abundance of wild bumblebees in Vermont has plummeted over the last century, according to an analysis from researchers at the University of Vermont and Vermont Center for Ecostudies (VCE). This research adds fresh evidence to the growing realization that mankind is witnessing and contributing to, as the New York Times recently labeled, a worldwide insect apocalypse. “We’re losing bumblebees even before we fully understand their benefits to our economy and well-being, or how they fit into ecosystems,” said Kent McFarland, study coauthor and conservation biologist at VCE in a press release. Researchers conducted surveys with the help of 53 trained citizen scientists. Alongside the researchers, these individuals surveyed bumblebee populations through a combination of photos of wild bees and net collections. In total, over 81% of the state’s municipalities were included in the survey, representing all of Vermont pollinator’s biophysical regions. These data, consisting of over 10,000 bee encounters, were then compared to a database of almost 2,000 historical public and private insect collections amassed by researchers. With the first records beginning at 1915, scientists are able to compose a century-long assessment of pollinator populations in Vermont. “These collections are priceless,” […]

(Beyond Pesticides, December 4, 2018) In mid-November, the state whose agricultural operations used more than 900,000 pounds of chlorpyrifos in 2016 (down from two million pounds in 2005) moved to establish some temporary restrictions on its use. Regulators at the California Department of Pesticide Regulation (CDPR) issued interim restrictions on the compound while the agency works on a formal regulatory process to list chlorpyrifos as a “toxic air contaminant” and develop permanent restrictions on its use. A neurological toxicant, chlorpyrifos damages the brains of young children: impacts of exposure, even at very low levels, include decreased cognitive function, lowered IQ, attention deficit disorder, and developmental and learning delays. It was slated to be banned for food uses by the U.S. Environmental Protection Agency (EPA) last year, but the decision was reversed by the Trump administration. The interim measures in California include: banning aerial application of chlorpyrifos; ending its use on many crops — except for those determined to be “critical” by virtue of there being few, if any, alternatives (as determined by the University of California Cooperative Extension and listed on DPR’s website); establishing a quarter-mile buffer zone for 24 hours after any application of the pesticide; and requiring a 24/7/365, 150-foot […]
