(Beyond Pesticides, January 25, 2017) A study conducted at the University of Buffalo recently revealed a connection between two common insecticides and an increased risk for certain metabolic diseases, including diabetes. Researchers found that by binding to and disrupting melatonin receptors that control numerous physiological functions, chemicals such as insecticides can affect melatonin levels, creating a higher risk for metabolic diseases to develop. The study, Carbamate Insecticides Target Human Melatonin Receptors, was published in Chemical Research in Toxicology and was funded by a grant from the National Institute of Environmental Health Sciences, which is part of the National Institutes of Health. The implicated chemicals in this research, carbaryl and carbofuran, are notoriously dangerous carbamate insecticides. Carbamates share structural characteristics and an ability to inhibit acetylcholinesterase (AChE), an enzyme important for the transmission of nerve impulses. When AChE is inhibited, acetylcholine accumulates leading to overstimulation of neurotransmitters, resulting in muscle weakness, confusion, and paralysis, among other symptoms. Carbaryl is said by EPA to be “one of the most widely applied insecticides in the U.S.,” since use began in 1959, with 10-15 million pounds used annually. It is a broad-spectrum insecticide used on a variety of crops, in forestry and on ornamentals, in […]

(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 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 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 Biology’s 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. EPA’s final decision on registration of Enlist Duo is expected in early 2017. According to Paul Bonarrigo, owner of Messina Hof Winery in Texas, the “approval of these formulations will wind up affecting every vineyard up there.” This will have ramifications across Texas, as the wine industry contributed $1.88 billion to the state’s 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,“If we get […]

(Beyond Pesticides, December 22, 2016) Legislation passed Monday in the District of Columbia stops the use of toxic pesticides near schools, child-occupied facilities, waterbody-contingent property, and public property. The Pesticide Education and Control Amendment Act (PECCA) of 2016 (Bill B21-0580), passed unanimously by the District Council, strengthens previous law to protect children and residents living in Washington DC from unnecessary pesticide exposure. The law places the District at the forefront with other communities around the country that are phasing out the use of toxic pesticides in building and land management. The legislation, sponsored by Councilmember Mary Cheh, clarifies certain provisions of the original PECCA passed in 2012, which had not been implemented by the Department of Energy and Environment (DOEE) in accordance with the original spirit and intent of the law. The new law clarifies the department responsibility to prohibit all pesticide use near schools and waterbody-contingent properties, except a defined list of material allowed in organic land management. The law is intended to effect a transition to sustainable and cost-effective insect and weed management practices in the District. Jay Feldman, Executive Director of Beyond Pesticides, said: “This law protects vulnerable populations, like children, from the dangers of unnecessary toxic […]

(Beyond Pesticides, December 21, 2016) A California Department of Pesticide Regulation (DPR) report of all pesticide related illnesses in the state in 2014 identifies 1,685 cases “potentially involving health effects from pesticide exposure,” combining exposures from agricultural and non-agricultural use. Of the 798 cases associated with non-agricultural use, 18% of them (146 cases) involved exposure in children under 18 years old. The exposure rates are alarming, and only strengthen efforts by local activists in counties like Tulare to protect children from pesticide exposure. According to the report, Tulare County has the highest number of reported illnesses related to pesticide exposure at 78, followed by Santa Cruz County with 67. The report, Summary of Results from the California Pesticide Illness Surveillance Program 2014, provides a summary of illnesses identified by the Pesticide Illness Surveillance Program (PISP), a program under DPR. Of the 1,685 cases potentially involving health effects from pesticide exposure reported, DPR epidemiologists determined that 1,073 of those cases were “at least possibly associated” with pesticide exposure, representing a 5% decrease from 2013. However, even though the number of associated cases decreased in 2014, PISP did see a 14% rise in the number of associated episodes, defined as “an event in which a single source […]

(Beyond Pestimcides,  December 14, 2016) Preliminary research presented this week at the British Ecological Society’s annual meeting identifies yet another troublesome connection between the use of neonicotinoid pesticides and the health of bees, a critical pollinator species. The research links neonicotinoid use with an impaired ability of bees to learn to vibrate flowers and shake out the pollen, which is necessary for fertilization in crops like tomatoes and potatoes. This research is consistent with other studies that link neonicotinoid use to reduced learning in bees, as well as other impacts such as those on their colony size and  reproduction, as well as contributions to overall declines. Neonicotinoids (neonics) pesticides are a relatively new class of chemicals that affect plants in a systemic way, moving through the plants vacular system and expressed through pollen, nectar, and guttation droplets.  These pesticides, :which include  imidacloprid, thiamethoxam and clothianidin, have been found by  a growing body of scientific literature  to be linked to Colony Collapse Disorder, a phenomenon where bees experience rapid declines from hive abandonment and bee die-off,  and  pollinator decline in general.  Neonics are associated with  decreased foraging  and navigational ability, as well as increased vulnerability to pathogens and parasites as a […]

(Beyond Pesticides,  December 12, 2016)   On November 23, Bill Bader of  Bader farms, Missouri’s largest peach farm with over 1,000 acres and 110,000 peach trees, filed a suit against the multinational, agrichemical giant Monsanto. Mr. Bader seeks compensation for extensive damags to his peach trees, which he blames on the illegal, or non-labeled, use of the toxic herbicide dicamba, brought on by sales of Monsanto’s new, genetically engineered (GE), dicamba-tolerant crops. Mr. Bader is projected to lose $1.5 million in revenue from the crop damage. The case was filed in the Circuit Court of Dunklin County, an area that has been hit especially hard by alleged illegal dicamba spraying. The farm’s insurance company refuses to cover damages from any illegal herbicide use. Without compensation for the damages, the farm risks going out of business. The illegal use of dicamba in this case is not an isolated incident. There have been many disputes in the Midwest over the  illegal spraying of dicamba and subsequent crop damage due to pesticide drift.  Numerous news reports over the past two  months in southern soybean growing regions have found that many farmers are, in response to weeds on their farms that have become resistant […]

(Beyond Pesticides, December 8, 2016) On Monday, the Delaware Department of Agriculture (DDA) released its Managed Pollinator Protection Plan, which allows for the continuation of widespread pesticide use in landscapes across the state. The plan includes voluntary strategies for farmers, beekeepers, landowners and pesticide applicators, but fails to include any recommendations for reducing or eliminating toxic pesticide use. DDA resorts to recommending approaches that include “best management practices,” strategies to increase pollinator forage on public and private lands, and advocating for the use of Driftwatch, an online initiative that focuses on pesticide drift. Driftwatch is a voluntary effort run by the non-profit, Fieldwatch, which, according to its website, was created by Purdue University Agricultural and Biological Engineering and Agricultural Communications departments and  Purdue University Cooperative Extension Specialists  “to help pesticide applicators and specialty crop growers communicate more effectively to promote awareness and stewardship activities to help prevent and manage drift effects.” Like other state pollinator protection plans,  there is little mention of pesticides, despite the fact that neonicotinoids (neonics) are highly toxic, persistent and systemic pesticides that have been widely implicated as a leading factor in pollinator decline. According to environmentalists and beekeepers, little meaningful action has been taken to […]

(Beyond Pesticides, December 6, 2016) A new study released by researchers at the University of Washington, Seattle finds that exposure to organophosphate insecticides is associated with changes in oral bacterial diversity, particularly for exposed farmworkers. The study provides insight into the far-reaching changes pesticide exposure can cause to the human body, which are not captured by current risk assessment models used by the U.S. Environmental Protection Agency (EPA). Although past research has investigated the impact of pesticide exposure on the gut microbiome, this is one of the first studies to look at oral bacterial diversity. For the study, scientists took oral swabs from 65 adult farmworkers and 52 non-farmworker adults in the Yakima Valley of Washington State. Swabs were taken both during the spring/summer, when exposure to pesticides is high, as well as winter, when lower exposure is expected. At the same time the swabs were taken, researchers also took blood samples of individuals in the study. Scientists focused on exposure to the organophosphate insecticide Azinphos-methyl (AZM), which at the time of the study (2005-2006) had not begun its cancellation proceedings. Results show that farmworkers have greater concentrations of AZM in their blood than non-farmworking adults in the area. It […]

(Beyond Pesticides, December 5, 2016) People across the country can support farmworker children and rural communities by speaking up in support of better protection of California school children from pesticide exposure by December 9, 2016. Send a  short email to the California Department of Pesticide Regulation (DPR) ([email protected]) to tell the Department it  must expand proposed buffers around schools to one-mile to protect school children during and after school hours, and expand the rule to cover all schools and daycare centers. Given that, according to the California Department of Food and Agriculture’s latest statistics, “Over a third of the country’s vegetables and two-thirds of the country’s fruits and nuts [and a large share of dairy and livestock] are grown in California,” everyone who eats food in the U.S. has a stake in protecting children who live in the communities where the food is grown. Food purchasing decisions have a direct impact on the people who work on farms, their children, and the communities where they live. Support the more than 75 parents, teachers and advocates for social and environmental justice who marched in Tulare County to DPR’s draft rules for pesticides use near schools last week. Led by members of […]

(Beyond Pesticides, December 2, 2016) Last week, the Arkansas Plant Board voted 12-0 to push measures that would ban or limit the use of certain forms of the toxic herbicide dicamba in the state. The hearing was called to address proposals that the board released for public comment on September 30, such as banning certain formulations of dicamba outright, creating restrictions on the time of year that other formulations of the herbicide can be used, and creating buffer zones in certain situations. This decision comes on the heels of a newly registered formulation of dicamba by the Environmental Protection Agency (EPA), and widespread reports of crop damage across the Midwest and Southeast due to the illegal use of dicamba before it was registered. According to DTN Progressive Farmer, the three-hour public meeting was packed with almost 200 people, and approximately 20 of those testified. The testimonies highlighted the disputes and tensions that have arisen over the use of dicamba, as many remembered and spoke about Mike Wallace, a farmer who was tragically murdered on October 27 during an argument with a fellow farmer in Missouri over the illegal use of the chemical and subsequent crop damage. “We’ve seen exactly what […]

(Beyond Pesticides,  November 28, 2016) Last week, a  federal judge effectively  rubber stamped  U.S. Environmental Protection Agency (EPA) policies that allow seeds to be coated with bee-toxic pesticides known as neonicotinoids. These pesticides, persistent in water and soil, are associated with acute bee kills, widespread pollinator declines and environmental damage. The Judge’s Order was issued on Nov. 21 in the case of  Anderson et al. v. McCarthy, No. 3:16-cv-00068-WHA (N.D. Cal.). “It is astounding that a judge, EPA or anyone with any common sense would not regulate this type of toxic pesticide use, especially when the seed-coatings are so broadly applied and there is so much at risk. Study after study has shown that seeds coated with these chemicals are a major culprit in catastrophic bee-kills. Now more than ever our country’s beekeepers, environment and food system deserve protection from agrichemical interests, and it is EPA’s job to deliver it,” said Andrew Kimbrell, Director of Center for Food Safety. The neonicotinoids share a common mode of action that affects the central nervous system of insects, resulting in  paralysis and death. They include  imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam. Neonicotinoid pesticides have  consistently been implicated  as a key contributor […]

(Beyond Pesticides, October 3, 2016) On Friday, the California Department of Pesticide Regulation (CDPR) released a rule titled, Pesticide Use Near Schoolsites, that proposes limited restrictions for certain agricultural pesticide applications near schools and child day care facilities. CDPR, whose proposal  has been criticized by advocates as not adequately protective of workers and communities, is accepting public comments on the proposal until November 17, 2016. The  proposed rule, effective October 1, 2017, will require farmers to notify public schools and child day care facilities when “certain pesticide applications made for the production of an agricultural commodity near a school site are planned in the coming year and also a few days prior to the applications.” For pesticides applied via aircraft, airblast sprayer, sprinkler chemigation, and fumigation, there must be a minimum ¼  mile buffer around the school or child day care facility. While the move by CDPR is a step in the right direction, it is not rigorous enough and does not adequately protect the most vulnerable populations from pesticide exposure, according to advocates. The rule does not include private K-12 schools or family day care homes, a move that according to CDPR documents is due to the potential for […]

(Beyond Pesticides, August 4, 2016) Complaints about a green residue that appeared on golfers’ shoes at Rye Golf Club in New York last spring prompted an investigative report by The Journal News/lohud.com, that  revealed what reporters are describing a region-wide “environmental toxic time bomb” caused by the over and misuse of pesticides throughout the state. The investigation uncovered (i) gaps in the oversight of millions of pound of toxic pesticides applied throughout the Lower Hudson Valley, (ii) heightened health risks in Westchester and Rockland counties where pesticides are used the most, (iii) significant flaws in pesticide data collected in the state of New York, and (iv) the failure of authorities to catch the illegal sale and use of unregistered pesticides. Rye Golf Club, which turned into a “field of dustbowls” within weeks of the green residue appearing on golfer’s shoes, had to close 18 putting greens, leading members to demand thousands of dollars in refunds and city leaders to address the severely damaged city-owned golf course. The cause of the mysterious green residue was later revealed to be the result of an application of a contaminated batch of the fungicide ArmorTech ALT 70, whose active ingredient is azoxystrobin. Rye Golf […]

(Beyond Pesticides, August 3, 2016) Home pest control giant Terminix reached a tentative settlement agreement this week of $87 million with  the  Esmond family for the severe poisoning of the mother, father and two teenage children with the highly neurotoxic pesticide fumigant  methyl bromide.  The company treated  a neighboring unit  to  their vacation residence  last spring  at a  condo resort complex in St. John, U.S. Virgin Islands. This amount is in addition to $3 million already paid to the family to cover the insurance deductible, and an undisclosed amount that the company’s insurance carriers have agreed to pay pursuant to their general liability insurance policies, according to an earnings report filed by the Terminix’s parent company, ServiceMaster Global Holdings, Inc. of Memphis, Tennessee. Stephen Esmond became paralyzed after the March 2015 incident, while his two sons spent weeks in critical condition. The mother,  Theresa Devine is still recovering. Beyond Pesticides’ executive director, Jay Feldman, spoke to CBS Evening News August 2 on the poisoning. Watch news piece  here.   Methyl bromide is a restricted use pesticide and is not registered for residential use, according to the U.S. Environmental Protection Agency’s (EPA) 2013 Methyl Bromide Preliminary Workplan. It was taken off […]

(Beyond Pesticides, July 19, 2016) Exposure to common pesticides at levels often found in the environment can have subtle but significant impacts on the behavioral health of fish, amphibians and other aquatic invertebrates. According to researchers at Northern Arizona University, who analyzed data from nearly 40 experiments to reach their conclusion, fish and amphibians swam 35% slower and were 72% less active after pesticide exposure. Chemical Class Type Example Pesticides Carbamates Insecticide Carbaryl, Aldicarb Organochlorine Insecticide DDT, Endosulfan, Chlordane Organophosphates Insecticide Diazinon, Chlorpyrifos Organotins Biocide Tributyltin Phosphonoglycines Herbicide Glyphosate, Glufosinate Pyrethroids Insecticide Permethrin, Bifenthrin, Esfenvalerate Triazines Herbicide Atrazine, Simazine The study, published in Science of the Total Environment, found that the overall effect on aquatic wildlife varied based on the chemical class the animals encountered. While pyrethroids, carbamates, and organophosphates resulted in a significant decrease in swim speed, triazines and phosphonoglycines showed no overall effect. Pyrethroids, carbamates, organophosphates, organochlorines, and organotins decreased activity, while phosphonoglycines had no overall effect, and triazines actually increased activity. “I didn’t think that we would see [an effect] across such a wide range of pesticides so consistently, but we did,” said study co-author, Catherine Propper, PhD to KNAU, “and that leads to some concerns about […]

(Beyond Pesticides, July 8, 2016) Researchers at the University of Montana (UM) recently released a study that found a lack of government data and accountability on  the use of herbicides on public lands to kill invasive and non-native plants. The report raises serious questions about the widespread management practice, which the researchers say may be causing more harm than good. UM researchers, Cara Nelson, Ph.D. and Viktoria Wagner, Ph.D., along with two researchers from Canada, looked at government agencies and agricultural statistics companies in the U.S., Canada, and Mexico to find their data. The study found that the government agencies in Canada and Mexico kept no archived database of herbicide usage for invasive plant management. In the U.S., five out of seven agencies that were contacted by the researchers tracked herbicide usage, and only four of those agencies shared their data. These agencies include the Bureau of Indian Affairs, Bureau of Land Management, Fish and Wildlife Service, and National Park Service. The U.S. Forest Service, which oversees 193 million acres in the U.S., declined to share its data on herbicide use. The report found that even the agencies that did share their data did not consistently archive information on the […]

(Beyond Pesticides, June 1, 2016) A study  by researchers at Purdue University has concluded  that honey bees collect most of their pollen from non-crop plants that are frequently contaminated with agricultural and urban pesticides. The researchers found this to be true even in places where croplands dominate the area.  The study, which detected neonicotinoids, pyrethroids, fungicides, and others, highlights the large number of toxic pesticides to which bees are exposed to in the environment. Researchers collected pollen from Indiana honey bee hives at three sites over 16 weeks. The hives were placed in a variety of settings, such as an open meadow with wildflowers, woody shrubs and trees present (non-agricultural), the border of a corn field that was treated with the neonicotinoid clothianidin and three fungicides, and the border of a non-treated corn field. The pollen samples that were collected by the bees represented up to 30 plant families and contained residues from pesticides spanning nine chemical classes. The researchers found 29 pesticides in pollen from the meadow site, 29 pesticides in pollen from the treated cornfield, and 31 pesticides in pollen from the untreated cornfield. The most common chemical products found in pollen from each site were fungicides and […]

(Beyond Pesticides, May 17, 2016) It was 10 years ago that commercial beekeepers first reported widespread, unsustainable winter losses of their honey bee colonies. A decade after the alarm was first sounded on pollinator declines, results of 2015-16 Colony Loss Survey show no sign the crisis of abating. According to the Bee Informed Partnership survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. Beekeepers factor in that a small percentage, <15% of their colonies, will be lost each winter, but do not expect to lose colonies during the summer, when there is amble forage and nectar for bees. The costs beekeepers must incur to keep their hives alive continue to increase. More time and money is spent to maintain their hives, yet losses continue to be staggering ”” and unsustainable. As colony collapse disorder (CCD), the cryptic loss of honey bee colonies with no sign of dead bees in or around the hive, has faded from public discussion, concerns over pollinator declines in general, from bees […]

(Beyond Pesticides, April 21, 2016) A report released Tuesday by the Alliance for Natural Health (ANH) shows that glyphosate residues are widely distributed in common breakfast foods, such as bagels, cereals, creamers, and eggs. Glyphosate is a pervasive and toxic chemical found in Monsanto’s Roundup weedkiller and was classified by the International Agency for Research on Cancer (IARC) as a probable human carcinogen in 2015. The report looks at conventional and organic-certified versions of 12  popular breakfast foods and ingredients (a total of 24 items) and finds that many of the sample foods or ingredients contain detectable levels of glyphosate. Testing was done by an independent laboratory using the ELISA (enzyme-linked immunosorbent assay) method. Categories tested were: flour, corn flakes, instant oatmeal, bagels, yogurt, bread, frozen hash browns, potatoes, cream of wheat, eggs, non-dairy creamers, and dairy based coffee creamers. Of note is the finding that a sample of organic cage-free eggs contain more glyphosate than the allowable tolerance level. The lab found glyphosate residue levels of 169 parts per billion (ppb), while the allowable tolerance level is only 50ppb. The report acknowledges that the effects of other chemical ingredients in glyphosate formulations have not been evaluated, and the consequences […]

(Beyond Pesticides, March 31, 2016) On Tuesday, Terminix International LP and its U.S. Virgin Islands (USVI) operation agreed to a $10 million plea agreement after being  charged by the U.S. Justice Department and Environmental Protection Agency (EPA)  in U.S. District Court with multiple violations of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) for “illegally applying fumigants containing methyl bromide in multiple residential locations in the U.S. Virgin Islands.” This decision by Terminix to pay criminal fines comes just one year after a Delaware family of four was poisoned with the neurotoxic pesticide at a resort in St. John, resulting in hospitalization and serious injury. The agreement, which is still subject to District Court approval, requires Terminix USVI to pay $6 million in fines and restitution to EPA for response and clean-up costs, and Terminix LP to pay $3 million in fines and fund a $1 million community service project, and a probation period of three years. In addition, Terminix LP is also responsible for resolving past and future medical expenses for the family through separate civil proceedings. Last March, a family from Delaware was vacationing at a  luxury condo in the U.S. Virgin Islands when they were exposed to […]
