Monsanto Papers Redux: More on Industry Suppression and Regulatory Collusion

Friday, August 11th, 2017

(Beyond Pesticides, August 11, 2017) On August 1, a second round of internal Monsanto documents became public, stirring up additional questions and speculation about Monsanto’s potential malfeasance — i.e., its efforts to hide information about impacts of its popular glyphosate-based herbicide, Roundup. This follows on the heels of the March 2017 unsealing, by federal judge Vince Chhabria, of internal Monsanto documents — the “Monsanto Papers” — that evidenced questionable research practices by the company, inappropriate ties to a top EPA official, and possible “ghostwriting” of purportedly “independent” research studies. This latest release, of more than 700 documents, came courtesy of Baum, Hedlund, Aristei & Goldman, one of many law firms representing thousands of families who claim that exposure to Roundup caused non-Hodgkins lymphoma (NHL), a blood cancer, in their loved ones. Such litigation has been triggered, in part, by the 2015 finding of the International Agency for Research on Cancer (a branch of the U.N.’s World Health Organization) that glyphosate is “probably carcinogenic to humans.” The plaintiffs allege that the combination of glyphosate and surfactants used in Monsanto’s Roundup products is even more toxic than glyphosate alone, and that Monsanto has sought to cover up that information. Monsanto has continued to […]

Reports of Increasing Honey Bee Colonies Mask Continuing Pollinator Crisis

Thursday, August 10th, 2017

(Beyond Pesticides, August 10, 2017)  New data released by the U.S. Department of Agriculture (USDA) earlier this month, indicating a slight increase in the number of honey bee colonies, is masked by beekeepers’ efforts to split hives in the face of losses. The USDA reports that Colony Collapse Disorder losses (CCD) are down 27% compared to the past year. While these numbers may seem to be a positive sign after over a decade of consistent pollinator declines, they are more indicative of a beekeeping industry that is using every available tactic possible to stay viable. With the continued use of highly toxic neonicotinoid insecticides in farms, gardens, and public spaces throughout the country, the long-term health honey bees and other pollinators continue to be in jeopardy. According to USDA’s National Agricultural Statistics Service (NASS), the number of beekeeping operations with five or more colonies reported a total of 2.89 million colonies in April 2017, a 3% increase from April 2016, when numbers stood at 2.80 million. News media such as Bloomberg hailed this report in an article headlined “Bees Are Bouncing Back From Colony Collapse Disorder.” However, a closer look into the numbers and beekeeper accounts reveals what is actually occurring. A more accurate […]

Glyphosate Stresses Tadpoles to Produce More Venom

Wednesday, August 9th, 2017

(Beyond Pesticides, August 9, 2017) Common toad tadpoles express more venom when chronically exposed to glyphosate herbicides, a study published last month in Proceedings of the Royal Society B indicates. Glyphosate, an increasingly controversial chemical found in Roundup brand herbicides produced by Monsanto, has been linked to a range of adverse impacts in both wildlife and people. The results of this research indicate a need to reduce the use of glyphosate in our environment to ease chronic stressors to sensitive wildlife like amphibians. Scientists tested the effects of formulated glyphosate products on toad tadpoles through experiments in a laboratory setting, as well as a mesocosm, a controlled outdoor environment that replicates natural conditions. Tadpoles in the lab were split into a series of groups which were each exposed to varying levels of glyphosate, some for the duration of the experiment, and others for 9 day periods during different stages in their development. For mesocosm tadpoles, researchers set up large plastic tubs and created small self-sustaining ecosystems with pond water and beech leaves. Glyphosate herbicides were added to certain tubs at either low or high concentrations. Both lab and mesocosm experiments had control tadpoles not exposed to any glyphosate herbicides. Tadpoles […]

Crop Damage from Monsanto’s Herbicide Dicamba Being Investigated in 17 States, Pointing to New Formulation Used in GE Fields

Tuesday, August 8th, 2017

(Beyond Pesticides, August 8, 2017) More than 1,400 official complaints of crop damage related to the herbicide dicamba have been recorded across 17 states this year, leading some to question a new formulation of the chemical used in genetically engineered (GE) fields. Dicamba, a toxic pesticide prone to drift off the target site, has been used in agriculture for decades. However, new GE crops developed by Monsanto must be paired with specific formulations of dicamba, and until now many believed these drift incidents were the result of illegal formulations of dicamba being applied to fields. But the extent of damage now being observed, covering over 2.5 million acres, is casting doubt on this theory, and raising more questions as to whether the new dicamba formulation is actually the cause of the widespread drift damage. Fruits and vegetables, as well as other crops that are not genetically engineered to tolerate dicamba are often left cupped and distorted when exposed to the chemical. Monsanto, DuPont Co. and BASF SE sell new formulations of the herbicide for use on dicamba-tolerant soybeans and cotton, and state enforcement officials and farmers have attributed last year’s damage incidents to off-label uses of older dicamba products. Initial reports began to surface […]

Chronic Pesticide Exposure at Work Tied to Breathing Disorders

Thursday, August 3rd, 2017

(Beyond Pesticides, August 3, 2017) Working in close contact with pesticides over the course of one’s lifetime increases the risk of Chronic Obstructive Pulmonary Disease (COPD) and other breathing disorders, according to a study published in Thorax by a team of Australian researchers. While cigarette smoke remains the single leading cause of lung disease worldwide, there is growing interest in understanding the environmental exposures of individuals that develop breathing problems, but have never smoked. Given the growing list of pesticide-induced diseases, the study’s results reinforce calls for a change in pest management approaches that safeguard farmwokers and pest control operators. Researchers’ examination of pesticide exposure made use of a health study that first began in Tazmania in 1968, and tracked asthma prevalence in participants at ages 12, 18, and 30. With this background data in hand, researchers followed up with a subset of study participants, now roughly 45 years old, and were able to further analyze 1,255 participants via in-person laboratory tests. “Our study looked at long-term exposure to pesticides,” said Sheikh Alif, PhD, lead researcher of the study at the University of Melborne to Reuters. “[I]t is thought that long-term exposure to pesticides increases mucus secretion and muscle contraction […]

August’s PolliNATION Pollinator of the Month – The Pollen Wasp

Wednesday, August 2nd, 2017

(Beyond Pesticides, August 2, 2017). August’s PolliNATION Pollinator of the Month is the Pollen Wasp! Pollen wasps, of the small subfamily Masarinae are the only “vegetarian” wasp in the family Vespidae., They feed solely on nectar and pollen, unlike their more aggressive Vespid wasp cousins. There are 300 species of pollen wasp from 14 genera spread across the globe, however, in the U.S., all 14 species of pollen wasps originate from the genus Pseudomasaris. Range Pollen wasps are found throughout the world, though they tend to concentrate in arid areas of southern Africa, and North and South America. They are not documented in the tropics or in Antarctica. In the United States, they can be found from Washington to as far south as New Mexico, and as far east as Nebraska. They are solitary pollinators who make their nests out of mud, often attached to branches, rocks, or hanging off ledges. Diet and Pollination Pollen wasps differ from their omnivorous Vespid wasp relatives by rearing their young on nectar and pollen, rather than other insects. They are the only Vespid species which do so. Their nests, made up of a mixture of soil and nectar, are usually comprised of 4-10 […]

Government and Chemical Industry Collusion Going Back Decades Showcased in “Poison Papers”

Tuesday, August 1st, 2017

(Beyond Pesticides, August 1, 2017) A collection of long archived documents dating back to the 1920s were released last week showcasing the efforts of the chemical industry and the federal government to conceal from the public the real dangers associated with the use and manufacture of chemical products. The Bioscience Resource Project and the Center for Media and Democracy released more than 200,000 pages of these documents now accessible on the “Poison Papers” website. First reported in The Intercept, the project, “Poison Papers,” makes publicly available documents obtained through legal discovery in lawsuits against Dow, Monsanto, the U.S. Environmental Protection Agency (EPA), the U.S. Forest Service, the Air Force, and pulp and paper companies, among others. Activist Carol Van Strum stored much of these documents in her rural Oregon barn. Ms. Van Strum’s activism on pesticides and other toxic chemicals began in the mid-1970s, when she and her neighbors in Oregon filed a lawsuit against the U.S. Forest Service to stop the spraying of 2,4,5-T, a dangerously toxic herbicide that made up one-half of the ingredients in the deadly Agent Orange (the other ingredient was the still widely used herbicide 2,4-D). The spraying directly doused her four children, who developed headaches, nosebleeds, and bloody diarrhea. Miscarriages […]

Toxic Ingredients Found in Various Mac and Cheese Products

Friday, July 28th, 2017

(Beyond Pesticides, July 28, 2017) According to a report released earlier this month by the Coalition for Safer Food Processing and Packaging, a national alliance of leading public health and food safety groups, toxic, hormone disrupting, industrial chemicals have been found in 10 varieties of macaroni and cheese products. The coalition is calling on food companies, especially the Kraft Heinz Company, maker of the iconic boxed mac and cheese, to eliminate sources of these chemicals from their cheese products. The tested mac and cheese products contained elevated levels of phthalates, chemicals used in industrial processing of plastics, adhesives and rubber, among other things, as well as “inert” ingredients in pesticide products. The study tested 30 items of individual cheese products from various manufacturers that were purchased at retail grocery stores in the U.S and shipped to the lab, unopened, in their original packaging. The cheese product items tested include nine of Kraft’s many cheese products. Results found that nearly every cheese product tested contained 10 different phthalates, with six found in a single product. Eight of the nine Kraft mac and cheese products tested contained phthalates. DEHP, a phthalate currently banned in several countries, was found in 10 of the mac […]

Bill to Ban Neurotoxic Chlorpyrifos Introduced in the U.S. Senate

Thursday, July 27th, 2017

(Beyond Pesticides, July 27, 2017) Earlier this week U.S. Senators Tom Udall (D-NM) and Richard Blumenthal (D-CT) introduced a bill that would ban use of the insecticide chlorpyrifos. The Protect Children, Farmers and Farmworkers from Nerve Agent Pesticides Act, S. 1624, comes one week after an appeals court refused to require the U.S. Environmental Protection Agency (EPA) to make a decision over whether to ban the chemical. Removing this neurotoxic insecticide from the environment would significantly reduce health risks for children and farmworkers in underserved rural communities, build pressure to address all toxic organophosphates, and help push U.S. agriculture in a more sustainable direction. As with other organophosphate class chemicals, chlorpyrifos, first registered in 1965 by Dow Chemical, is derived from nerve agents used during World War 2. The chemical is linked to a range of negative health and environmental outcomes that warrant its prohibition. Children are at particular risk from the chemical due to their developing immune, organ, and nervous systems.  As with other organophosphate nerve agents, the chemical acts on the body’s nervous system, inhibiting the movement of neurotransmitters called cholinesterase. Chlorpyrifos chemically binds to the site where cholinesterase would in the body, preventing normal nerve impulse transmission. […]

EPA Rejects Pesticide Use in Cannabis Production, Paves Way for Organic Marijuana

Tuesday, July 25th, 2017

(Beyond Pesticides, July 25, 2017) With the legalization of medical and recreational marijuana in dozens of states, the question of pesticide use in commercial cannabis production and resulting residues in a range of products is a burning issue. The U.S. Environmental Protection Agency (EPA) injected itself into this question when last week it issued a notice of intent to disapprove the planned registration of four pesticides for cannabis production by the state of California. Given cannabis’ narcotic status by the federal government, EPA does not register pesticides for use in marijuana production. However, states and previously EPA have considered using a Special Local Needs (SLN) permit under the nation’s pesticide law, the Federal Insecticide Fungicide and Rodenticide Act (Section 24c), to allow this unregistered pesticide use to meet an “existing or imminent pest problem.” While reports suggest that EPA’s rejection is likely politically motivated based on the current administrator’s opposition to cannabis legalization in general, the agency’s determination is consistent with Beyond Pesticides’ letters to states and EPA, which encourage the burgeoning industry to root itself in organic production, without the use of toxic pesticides. “The cannabis industry has the opportunity to develop with organic soil management and fertility practices that […]

Sustained Glyphosate Use Reveals Risks to Soil and Environmental Health

Friday, July 21st, 2017

(Beyond Pesticides, July 21, 2017) A March 2017 review of studies on the agricultural use of glyphosate (the active ingredient in “Roundup” and other formulated herbicides) points to widespread persistence in soils subject to long-term, intensive glyphosate use, and myriad resulting concerns about impacts on soil and environmental health. The review, by Robert J. Kremer, PhD, of the University of Missouri School of Natural Resources, cites concerns that include: reduction of nutrient availability for plants and organisms; disruption to organism diversity, especially in the areas around plant roots; reductions of beneficial soil bacteria; increases in plant root pathogens; disturbed earthworm activity; reduced nitrogen fixing at plant roots; and compromised growth and reproduction in some soil and aquatic organisms. Globally, glyphosate is the most widely used herbicide compound: in 2017, worldwide use is estimated to be approximately 1.35 million metric tons. Use in the U.S. has risen dramatically — from 2.72–3.62 million kg in 1987 to approximately 108 million kg in 2014, and 15-fold since 1996, when genetically engineered (GE) glyphosate-tolerant crops were introduced. Use has grown for a number of reasons, including more-intensive use as resistance to the herbicide grows. Researchers have found that, after years of consistent application to […]

Petition Filed to Compel EPA to Review All Pesticide Product Ingredients

Monday, July 17th, 2017

(Beyond Pesticides, July 17, 2017) Last week, Center for Food Safety (CFS) filed a legal petition demanding major updates and improvements to the U.S. Environmental Protection Agency’s current review of pesticides. The petition specifically seeks to compel EPA to require that pesticide companies provide safety data on all ingredients of a pesticide products, or formulations, both active and inert. The agency generally only requires data on a pesticide product’s active ingredient, despite evidence of potential hazards associated with synergism between ingredients, including inert (undisclosed) ingredients, and other pesticides applied in combination. According to Amy van Saun, attorney with CFS, “EPA’s job is to ensure pesticides are safe for children, families, and the environment, but numerous pesticides have other ingredients or combined effects that are causing significant risks and harm. EPA’s outdated and insufficient safety assessment endangers the public welfare and must be brought into the 21st century.” The CFS petition requests the following actions from EPA: Revise pesticide registration regulations to take into account all pesticide ingredients (active, inert and adjuvant) and their effects on the environment. Revise pesticide registration regulations to require whole pesticide formulation and tank mixture testing to take into account synergistic effects. Revise pesticide registration regulations to require inert […]

After Extensive Crop Damage, AR and MO Issue Temporary Ban on Sale and Use of Weedkiller Dicamba

Thursday, July 13th, 2017

(Beyond Pesticides, July 13, 2017) Over the past week, both Arkansas and Missouri issued bans on the sale and use of the weedkiller dicamba by farmers because of crop damage associated with the pesticide’s drift off treated fields. On Friday, July 7, the Arkansas Agriculture Department announced this emergency 120-day ban, which raised civil penalties for misuse of the toxic herbicide from $1,000 to a maximum of $25,000. The same day, the Missouri Department of Agriculture announced a temporary “Stop Sale, Use or Removal Order” on all dicamba products in the state labeled for agricultural use. Dicamba has been linked to damage of the kidney and liver, neurotoxicity, and developmental impacts. The chemical has a strong propensity to volatilize small particles of the herbicide into the air and drift far off-site. Sensitive crop species can be damaged by dicamba at levels in the parts per million. As of July 7, nearly 600 complaints of dicamba danage have been filed by Arkansas farmers in 23 different counties. In Missouri, as of July 3, there are 123 cases of dicamba injury complaints under investigation and according to the Missouri Soybean Association, “more than 200,000 Missouri soybean acres currently show signs of suspected dicamba […]

Washington Oyster Growers Request Approval to Apply Neonicotinoid in Aquatic Environments

Thursday, July 6th, 2017

(Beyond Pesticides, July 6, 2017) The Washington State Department of Ecology (Ecology) is evaluating a new permit application for the use of imidacloprid, a toxic neonicotinoid, to combat a growing native population of burrowing shrimp that threatens oyster beds in Willapa Bay and Grays Harbor in Washington state. The application was recently submitted to Ecology by a group of oyster farmers from the Willapa Grays Harbor Oyster Growers Association (WGHOGA), who “propose to use the pesticide to treat tide lands to support their aquaculture practices.” Imidacloprid is known to be toxic to bees and aquatic organisms, raising questions on the impacts of its use on the long-term ecological health of the bays. In April 2015, much to the dismay of activists and concerned local residents, Ecology approved a permit submitted by oyster farmers for the use of imidacloprid to combat burrowing shrimp in these aquatic ecosystems. But with a nationwide public outcry, the permit was withdrawn in May 2015. The recent request that was submitted differs in several ways from this 2015 permit, including: The new permit proposes treating 485 acres in Willapa Bay and 15 acres in Grays Harbor, compared to 2,000 acres combined from both water bodies in the 2015 permit. The oyster farmers […]

Polli-NATION Pollinator of the Month: The Hoverfly

Wednesday, July 5th, 2017

(Beyond Pesticides, July 5, 2017) The Hoverfly is July’s pollinator of the month. Hoverflies, also known as flower flies and syrphid flies, are members of the “true fly” order Diptera, family Syrphidae. There are roughly 200 genera and 6,000 species of hoverflies throughout the world. Range Hoverflies are commonly seen in in flowering landscapes across the globe. According to the United States Forest Service (USFS), there are almost 900 species of the family in North America. They live in a range of habitats, including decaying wood, still and moving freshwater, on plants, and sometimes even in other insects’ nests. They are not often found in desert regions, and no known species have been discovered in Antarctica. Diet and Pollination The diet of hoverflies varies widely among species. In general, they are vital pollinators for a range of common flowering plants. Most adult flower flies have generalized mouthparts structured to sap up nectar and harvest pollen from open flowers; others use a long, beak-like proboscis to imbibe nectar from tube-shaped flowers; and some reportedly feed on the honeydew secreted from aphids. Because certain syrphid flies will feed on human perspiration, they are often mistaken for sweat bees. Unlike sweat bees, however, […]

Largest Field Study Finds Neonicotinoids Decimate Bees

Monday, July 3rd, 2017

(Beyond Pesticides, July 3, 2017) A two-year long study conducted at 33 sites in multiple European countries to assess the effects of neonicotinoid (neonics) insecticides on three bee species in real-world environmental conditions confirms that these pesticides have a deleterious effect on bee survival. The study, the largest of its kind, explored the role of the agricultural use of neonics as seed coatings on bee health and fnds that the pesticides are persistent in the environment, contaminating pollen and nectar that bees forage, reducing colony fitness. The results of the study support ongoing calls for a ban on neonics, including a European Union (EU) wide ban proposed earlier this year. The new research, published in the prestigious peer-review journal Science, which was in part funded by Bayer and Syngenta – manufacturers of the pesticides, encompassed large field experiments to assess the effects of neonic-treated crops on various bee species –honey bees (Apis mellifera), bumble bees (Bombus terrestris), and solitary bees (Osmia bicornis)– across three European countries (Germany, Hungary and the United Kingdom). The study examines the impacts of clothianidin and thiamethoxam, the neonics frequently used as seed coatings of oil seed rape (canola), and used in the fields under study. […]

Did Dow Chemical Influence the EPA Administrator’s Decision to Reverse Chlorpyrifos Ban?

Friday, June 30th, 2017

(Beyond Pesticides, June 30, 2017) Scott Pruitt, Administrator of the U.S. Environmental Protection Agency (EPA), met privately with Dow Chemical’s CEO several weeks before reversing EPA’s tentative decision to ban chlorpyrifos, according to records recently obtained by the Associated Press (AP). A copy of Mr. Pruitt’s schedule reveals he met with Dow CEO, Andrew Liveris, on March 9 at a Houston hotel and “twenty days later Pruitt announced his decision to deny a petition to ban Dow’s chlorpyrifos pesticide from being sprayed on food.” At a hearing this week, U.S. Senator Tom Udall (D-NM) pressed Mr. Pruitt to name a peer-reviewed study that indicates that chlorpyrifos is safe. Mr. Pruitt answered by saying that “he had relied on ‘interagency dialogue’ with USDA [U.S. Department of Agriculture] before denying the petition to ban the chemical.” In a congressional hearing earlier this month regarding chlorpyrifos’ safety, Mr. Pruitt stated that his decision was founded on “meaningful data and meaningful science.” However, AP followed up with EPA to provide details on this science, and Mr. Pruitt’s office replied with quotes from trade groups and USDA, but failed to provide any scientific studies on the chemical’s safety. In March 2017, in an about-face, EPA’s Administrator […]

European Chemicals Agency Classifies BPA as an Endocrine Disruptor

Thursday, June 29th, 2017

(Beyond Pesticides, June 29, 2017) On June 16, the European Chemicals Agency (ECHA) decided to classify bisphenol A (BPA) as an endocrine disruptor, and as a substance of “very high concern” due to “probable serious effects to human health.” The classification follows a proposal by the French food security agency (ANSES), which was made earlier this year. The committee, comprised of representatives from all 28 European Union EU countries, agreed to the classification unanimously. With pressure from environmental groups and others, the European Commission (EC) is working to define scientific criteria that will be used to identify endocrine disrupting chemicals (EDCs), and lead to more effective regulation in EU countries. In June 2016, the EC issued weak regulations on endocrine disruptors in pesticide products, undermining the precautionary legal standard that governs pesticide usage in Europe. Many scientists and advocacy organizations criticized the proposed regulations for creating an impossibly high burden of proof for defining harm from endocrine disrupting pesticides and other products. EDCs contained in common household products such as detergents, disinfectants, furniture, plastics, and pesticides, interfere with the body’s hormone system either by mimicking naturally produced hormones, blocking hormone receptors in cells, or effecting the transport, synthesis, metabolism or excretion […]

French Prime Minister Retains Bee-Toxic Neonicotinoid Pesticide Ban

Tuesday, June 27th, 2017

(Beyond Pesticides, June 27, 2017) French Prime Minister, Edouard Philippe, is retaining the neonicotinoid (neonic) pesticide ban, which is set to go into effect in 2018 and is stronger than the current European Union restrictions on neonics. This decision follows a disagreement with French Agriculture Minister, Stephane Travert, who was in favor of relaxing the ban and told media outlets that he wants to address “the possibility of a number of exemptions until we find substitution products.” In July 2016, lawmakers in France approved plans to ban neonicotinoid pesticides by 2018, based on their link to declining populations of pollinators, specifically bees. The outright ban on neonicotinoid pesticides in France was adopted by a narrow majority of the country’s National Assembly, as part of a bill to protect biodiversity. In March 2017, the European Commission (EC) proposed a complete ban of agricultural uses of the widely used bee-toxic neonicotinoid pesticides across Europe under draft regulations. The EC cites neonicotinoids’ “high acute risks to bees.” In 2013, three neonicotinoids were temporarily banned because of concerns about their high toxicity to bees. A vote by member states is still being awaited. In 2013, the European Commission voted to suspend the use of the neonicotinoid pesticides […]

Citing a Serious Health Threat, Over 200 International Scientists Call for Limit on Antibacterial Triclosan

Wednesday, June 21st, 2017

(Beyond Pesticides, June 21, 2017) More than 200 international scientists and medical professionals have signed the Florence Statement on Triclosan and Triclocarban, which states that triclosan and its chemical cousin triclocarban pose a risk to human health, and urges the international community to limit use of these antimicrobials, which are associated with bacterial resistance and no more effective than soap and water. In 2016 after manufacturers failed to prove efficacy, the U.S. Food and Drug Administration (FDA), which regulates cosmetic triclosan products, announced that manufacturers must, by September 2017, remove triclosan from over the counter hand soaps. The agency still allows the chemical in toothpastes and other products, such as hand wipes. The Environmental Protection Agency (EPA), which regulates triclosan in household items, textiles and plastics, still permits wide use of the chemical in a range of products. The Florence Statement on Triclosan and Triclocarban is “based on extensive peer-reviewed research,” and “concludes that triclosan and triclocarban are environmentally persistent endocrine disruptors that bioaccumulate in and are toxic to aquatic and other organisms.” The statement includes evidence of human health threats, and provides recommendations intended to mitigate harm from triclosan, triclocarban, and other similar antimicrobials. The recommendations are listed below: “Avoid […]

Aerial Mosquito Spraying Linked to Elevated Autism Rates

Thursday, June 15th, 2017

(Beyond Pesticides, June 15, 2017) Communities exposed to frequent aerial spraying for mosquito control experience elevated rates of autism diagnoses, according to new research. The study identifies the frequent use of synthetic pyrethroid insecticides, which are linked to neurocognitive and behavioral impacts, among other health effects. Pediatric researchers at Penn State University and the University of California examined communities in eight zip codes in Onondaga County, New York with frequent aerial spray programs for mosquito control, and contrasted these findings with communities in 16 zip codes that do not employ similar pesticide use programs. According to the study, between 2007 and 2009, the average yearly pesticide burden across the eight aerial exposed zip codes was approximately 11,000 kilograms, compared to approximately 4,000 kilograms of pesticide exposure across the 16 control zip codes. The study finds that the zip codes with frequent aerial pyrethroid exposure are 37% more likely to have higher rates of childhood developmental delays and autism spectrum disorder. The researchers acknowledge that the study establishes a correlational, not a causal, link between pyrethroid exposure and autism/developmental disorders, it adds to a growing body of research demonstrating an exposure-effect relationship between the two. Other studies have similarly linked developmental disorders and autism […]

(Beyond Pesticides, June 13, 2017) Prenatal exposure to commonly used mosquito and agricultural insecticides is associated with decreased motor function in infants, according to a study published in Environment International by a team of Chinese and U.S. researchers. The results of the study should give pause to insecticide-heavy efforts to control mosquitoes as the season ramps up this summer and fall. Frequent spraying as part of efforts to control Zika in Southern Florida last year resulted in large protests and calls for a preventive management approach not dependent on toxic chemicals. For the current study, over 350 pregnant Chinese mothers were tested for the presence of organophosphate pesticides in their umbilical cord blood. Researchers looked at exposure to the insecticides naled, methamidophos, trichlorfon, chlorpyrifos, and phorate. After giving birth, their children’s motor function was tested at both six and nine months of age. Tests included an analysis of the infant’s reflexes, locomotion, grasping, stationary and visual-motor integration abilities. Scores were categorized based on gross, fine, and total motor skills, and standardized quotients were created for each of the categories. Of the over 300 mothers, roughly 240 had detectable levels of one of the insecticides in their samples. Although no differences […]

Crops Damaged by Drift Widespread from Herbicide Dicamba Applied to GE Plants

Monday, June 12th, 2017

(Beyond Pesticides, June 12, 2017) Once again, there are reports that soybean and cotton fields are being damaged by off-site drift of the toxic herbicide dicamba. Last summer, farmers in Missouri, Arkansas, and Tennessee reported widespread crop damage from dicamba drift, which led to reduced yields. The U.S. Environmental Protection Agency (EPA) launched a criminal investigation at several Missouri locations into what they said was the illegal spraying of dicamba in October 2016. This year, reports of dicamba drift and damage are already being reported in Arkansas, and 25 formal complaints have already been filed, according to the state Plant Board. In summer 2016, illegal applications of dicamba damaged thousands of acres of soybeans, cotton, ornamental trees and fruits and vegetables. After numerous complaints, EPA launched a criminal investigation into the illegal spraying of dicamba, an investigation that is still ongoing. Many suspect that farmers who planted Roundup Ready 2 XtendÂŽ and XTENDFLEXÂŽ Cotton, the new dicamba-tolerant genetically engineered (GE) seeds in the region, when faced with a proliferation of pigweed, illegally sprayed dicamba across their fields leading to drift and off-site crop damage to other farmers. This year, although it is too early to say how many acres have been affected or what specific […]
