Another Lawsuit Blames Monsanto for Crop Loss

(Beyond Pesticides, July 26, 2018) A legal complaint filed by a Kansas farmer claims industry giant, Monsanto, knew its new dicamba-formulated product would harm other crops, but marketed and sold it anyway, damaging thousands of acres of crops. The lawsuit, filed by 4-R Farms based in Corning Kansas, lost over 200 acres of soybeans. This is the latest in a string of lawsuits Monsanto is facing. Farmers in Arkansas, Missouri, and elsewhere have been hit with crop losses as a result of the dicamba damage. Advocates  and victims of damage argue that Monsanto places profits ahead of possible damage to crops when it markets seeds resistant to a powerful weedkiller before making a less volatile herbicide available. This, according to the lawsuit filed in court. The petition, filed last week, could be the catalyst for a class action lawsuit of Kansas farmers against Monsanto, which faces a growing docket of legal challenges. The lawsuit also names chemical company BASF as a co-defendant. BASF is facing its own mounting pile of lawsuits over dicamba. The lawsuit requests unspecified damages and a trial by a federal jury in Topeka. Monsanto marketed its new line of dicamba products, Xtend, to go hand in hand with […]

State Proposes Rule to Restrict Sale of Dicamba and 2,4-D, Herbicides that Damage Crops

(Beyond Pesticides, April 4, 2018) In late March, the Missouri Department of Agriculture hosted a public hearing to discuss a proposed emergency rule restricting the sale and use of the herbicides dicamba and 2,4-D – which are known for their ability to drift off-site and damage sensitive crops. The emergency rule was introduced to prevent off-label use of specific dicamba or 2,4-D products. Thus far, dicamba is responsible for damaging approximately 325,000 acres of soybeans in the state last year. The proposed rule will stop sales of the herbicides dicamba and 2,4-D between April 15 and October 1 in Missouri. The department’s goal is to prevent off-label pesticides from drifting onto neighboring property and damaging other crops. According to the department, if it chooses to pursue an emergency rule, it could become effective as soon as April 1, 2018, and expire 180 days later. The rule also requires registrants to provide a sales record by April 30 for each pesticide sold between October 1 and April 15. A proposed rule will be filed at the same time as an emergency rule to initiate the formal rulemaking process. The draft rule language reads as follows: Pesticides that meet the conditions of this section are […]

Monsanto Loses Lawsuit to Stop Dicamba Ban in Arkansas

(Beyond Pesticides, February 23, 2018) Agrichemical corporation Monsanto has lost its bid to halt a statewide ban on the use of its specialty dicamba herbicide in Arkansas. Despite a lengthy process of evaluation and public comment that led to a prohibition on the use of drift-prone dicamba herbicides during the growing season on Arkansas farms, Monsanto made one last-ditch attempt to stop the law from going into effect by suing the entire state. With the industry’s loss, Arkansas is on track to implement the toughest restrictions against dicamba in the U.S. State Circuit Court Judge Chris Piazza dismissed the lawsuit last week based on a recent Arkansas Supreme Court ruling, which held that the state cannot be made a defendant in court. Monsanto’s lawsuit argued against the makeup of the state’s Plant Board, which voted to prohibit the company’s product last November. Monsanto also made claims that the state did not consider the economic damage a ban on the herbicide would cause, despite not seeking monetary restitution in court. Beyond Pesticides led a nationwide campaign to urge action by the Arkansas Plant Board to ban dicamba. Dicamba is an herbicide originally registered for use in 1967 to control broadleaf weeds. […]

Controversial Pesticides Jeopardize Endangered Species Like Salmon

(Beyond Pesticides, January 17, 2018) The organophosphate insecticides chlorpyrifos, malathion, and diazinon are likely to jeopardize the continued existence of endangered species and adversely modify their critical habitats, according to the newly released report from the National Marine Fisheries Service (NMFS). The insecticide cholorpyrifos, whose ban was rescinded by the Trump Administration last year, despite overwhelming evidence of neurological and brain damage to children, is once again being shown to be too toxic for continued use. Under Section 7 of the Endangered Species Act (ESA), any agency action requires a finding that it “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” The December 31, 2017 Biological Opinion from NMFS followed an ecological assessment that relied upon multiple lines of evidence to determine effects to species and their designated habitats. These include “the direct and indirect toxicity of each chemical to aquatic taxa groups (e.g. fish, mammals, invertebrates); specific chemical characteristics of each pesticide (e.g. degradation rates, bioaccumulation rates, sorption affinities, etc.); expected environmental concentrations calculated for generic aquatic habitats; authorized pesticide product labels; maps showing the spatial overlap of listed species’ habitats with pesticide use areas; […]

Protections from Agricultural Pesticide Drift over Schools Take Effect in California

(Beyond Pesticides, January 8, 2018)  With a long-documented history of children’s exposure to pesticides that drift from agricultural fields to school yards, California’s new regulations establishing no-spray buffers took effort January 1, as labor and public health groups acknowledged the progress and inadequacy of the measure. The new rule, DPR 16-004 Pesticide Use Near Schoolsites, adopted by the California Department of Pesticide Regulation (DPR), prohibits many pesticide applications within a quarter mile of public K-12 schools and licensed child day-care facilities during school hours, Monday through Friday between 6 a.m. and 6 p.m. This includes all applications by aircraft, sprinklers, air-blast sprayers, and all fumigant applications. In addition, most dust and powder pesticide applications, such as sulfur, will also be prohibited during this time. The new rule was announced in November, 2017. Advocates say the new rules fail to address persistent low-level exposures associated with the use of the pesticides near schools, which are in agricultural areas that are disproportionately Latino and from farmworker families. There is continuing concern about children’s exposure to hazardous pesticides because children use school grounds after school hours and on weekends and residues from drift may remain on school grounds. Many pesticides used are persistent and systemic, lingering […]

Take Action: Don’t Allow Dow Chemical to Poison Farms and Communities

(Beyond Pesticides, December 4, 2017) You told the Arkansas Plant Board to exercise its authority to protect farmers, consumers, and the environment from use of the herbicide dicamba on genetically engineered (GE) soybeans, and the board listened. Now, we need to ask the board to stop the use of 2,4-D on GE cotton. The action of states is critical as the federal government ignores basic safety concerns. Action in Arkansas will influence other states. Tell the Arkansas Plant Board to adopt the proposed rule and to prohibit use of 2,4-D on cotton! The decision concerning 2,4-D use on herbicide-tolerant cotton goes to the Arkansas Plant Board on December 12. The choice has many similarities to the decision to allow — and then prohibit — the use of dicamba on herbicide-tolerant soybean varieties. Both 2,4-D and dicamba are phenoxy herbicides — 2,4-D being the infamous ingredient (along with 2,4,5-T) of Agent Orange. Our voices were heard when the Arkansas Plant Board considered dicamba, so please weigh in on 2,4-D. At this December 12 meeting, the Arkansas Plant Board is holding a hearing on a proposed regulation that would allow the Board to request more information from pesticide registrants, which could support restrictions based on conditions within Arkansas.

New EPA Restrictions of Herbicide Dicamba, Prone to Drift, Criticized as Not Stopping Major Crop Damage

(Beyond Pesticides, October 20, 2017) Last week, the U.S. Environmental Protection Agency (EPA) announced that label changes to the herbicide dicamba would be made to try to minimize drift that has left thousands of acres of crops already damaged this season. The label changes include making dicamba “restricted use,” which allows only certified applicators to apply the chemical. Dicamba drift has been damaging farmers’ crops for at least two years due to the approval of new dicamba-tolerant genetically engineered (GE) crops. Advocates says that the new changes do not ensure that drift will be eliminated. According to EPA, the agency reached an agreement with the makers of dicamba, (Monsanto, BASF and DuPont) to restrict its application. This comes after hundreds of official complaints of crop damage related to dicamba across 17 states this year alone, leading to questions about the new formulation of the chemical used in genetically engineered (GE) crop productioon. New GE crops developed by Monsanto must be paired with specific formulations of dicamba, and thus led to a vast increase in dicamba use over the past couple growing seasons. Dicamba-based herbicide use has climbed dramatically as farmers have adopted, especially, Monsanto’s GE soybean seeds; in the 2017 season, 20 […]

Neurotoxic Pesticide Detected in Air at High Levels in California County

(Beyond Pesticides, August 29, 2017) Air monitoring in Kern County, California, finds levels of the highly neurotoxic pesticide, chlorpyrifos, in excess of the levels of concern established by the U.S. Environmental Protection Agency (EPA) for pregnant women. Chlorpyrifos is linked to low IQs, autism and other developmental neurological effects. Earlier this year, EPA Administrator Scott Pruitt refused to ban chlorpyrifos to the dismay of many scientists, medical professionals, and farmworker organizations. The California Department of Pesticide Regulation (CDPR) released its 2016 air monitoring data where it was revealed that chlorpyrifos air concentrations for a one-month period at the air monitoring site on the campus of Shafter High School in Kern County was 39.4 nanograms per cubic meter (ng/m3) – more than 18 times higher than EPA’s level of concern for pregnant women (2.1 ng/m3).  Shafter High School is some distance from fields in an area where chlorpyrifos use is not as high as in other parts of Kern County or elsewhere in California. More than 1.1 million pounds of chlorpyrifos was used in California in 2015, and more than a quarter of that is used in Kern County. High chlorpyrifos levels at a school means that children and unsuspecting teachers and […]

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

(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 […]

Agricultural Herbicide Use Threatens Oak Trees

(Beyond Pesticides, June 14, 2017)  Oak trees in Iowa may be the latest victim of widespread chemical-intensive agriculture, according reports in the Des Moines Register. The newspaper indicates that the Iowa Department of Natural Resources (IDNR) has received roughly one thousand calls this spring from residents concerned about the state of their oak trees. Leaves are ‘tattered’ down to the vein, in an appearance one would first think was related to pest damage, according to the newspaper article. However, foresters with IDNR indicate the cause is likely the use of chloroacetanillide herbicides, which are applied throughout the state and region. Advocates say that this situation contributes to mounting environmental problems associated with chemical-intensive food production that support the need for the adoption of non-toxic weed management strategies. Past research has found associations between the use of chloroacetanillide herbicides, such as acetochlor and metolachlor, and oak leaf tatter syndrome. State officials indicate that the increase in resident complaints is likely related to a colder March, which may have retarded leaf development. By the time leaves began unfurling in early spring, herbicide use was at its height, leading to high ambient concentrations of the chemicals in the atmosphere, according to IDNR officials […]

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

(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 Xtend® and XTENDFLEX® 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 […]

Environmental and Farm Groups Challenge Toxic Pesticides Used in Genetically Engineered Crops

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

California Weakens Rules to Protect Children from Pesticide Drift, Comment Period Open until April 4

(Beyond Pesticides, March 21, 2017) Last week, the California Department of Pesticide Regulation (CDPR) released revised rules regarding notification of pesticide applications near schools, weakening standards despite opposition from community and public health groups. The new rules rescind a requirement that schools be granted 48 hours prior notification for a planned application of agricultural pesticides within ¼ mile of a school site. CDPR has re-opened public comments on the new rules, and concerned residents have until April 4 to submit a short statement urging increased protections to the Department at [email protected] Public health, farmworker, and community groups had urged CDPR to strengthen, not weaken common-sense protections for children’s health. As the rules currently stand, applications of toxic, drift-prone pesticides will only be restricted within ¼ mile of a school site, and only during the hours of 6am to 6pm on weekdays. The original proposal required 48 hour prior notification for other agricultural pesticide applications occurring within ¼ mile of school sites during these times. However, CDPR’s revised rules now only require 48 hour notification if the pesticides applied are not on a list provided to school officials at the beginning of the year. Applicators will still be required to submit annual reports […]

Take Action: Bill Will Eliminate Permit Requirement to Spray Pesticides into Waterways

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

Ruling Affirmed in Colorado Pesticide Trespass Case

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

California Regulators Sued for Allowing Increased Use of Toxic Fumigant without Public Input

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

Common Pesticide Ingredient Labeled “Inert” Increases Honey Bee Susceptibility to Virus

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

North Miami Passes IPM Plan in Response to Local Activism

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

Groups File Federal Lawsuit Against Registration of Herbicide Dicamba, Used in Genetically Engineered Crops

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

Study Links Carbamate Insecticides to Diabetes and other Metabolic Diseases

(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 […]

University Scientists Dispute Syngenta Study Conclusion that Pesticide Is Low Risk to Bees

(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 […]

EPA Ignores Risks and Expands Uses of Toxic Herbicide Enlist Duo

(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, […]

More Evidence Neonics Inhibit Social Behavior and Pollination Skills in Bumblebees

(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 […]
