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

(Beyond Pesticides, November 1, 2018) A new study offers fresh evidence that wild bumblebee pollinators are particularly vulnerable to the impacts of neonicotinoid (neonic) insecticides, finding that exposure to these compounds interferes with mating success and population stability. Researchers from Worcester Polytechnic Institute in Massachusetts, measuring real-world harms of neonicotinoids, indicate that the impacts they found to bumblebee âreproducers,â namely queen and drone (male) bees, does not bode well for the array of plant species that relies on them. Though advocates warn that destabilizing managed pollinators could threaten U.S. food production and exports, with food prices increasing as cost of bringing pollinators to farms increases, the studyâs authors and advocates insist that the impacts of such widespread poisoning of wild bees could be felt well beyond agriculture. Researchers in the lab compare behavioral and psychological responses of virgin queens, workers, and male Bombus impatiens from multiple colonies to field-realistic doses of the neonicotinoid clothianidin. While every bee was given a replenishing supply of pollen based on body weight and energy demands, four distinct concentrations of diluted analytical-grade (pure) clothianidin (including a control with no pesticide added) were mixed into a nectar-like solution and fed to the bumblebees orally for 5 […]

(Beyond Pesticides, June 7, 2018) Health Canada is proposing to phase out a number of uses of neonicotinoids in order to mitigate risks to pollinators. The agency has completed its review of clothianidin and thiamethoxam — two neonicotinoids that have been linked to pollinator decline and finds risks of concern for bees. However, these measures do not go as far as those recently made in the European Union, but further than label restrictions issued by the U.S. Environmental Protection Agency (EPA). Health Canada concluded its Pollinator Re-evaluation for clothianidin and thiamethoxam after examining hundreds of laboratory and outdoor field studies that examined the possible effects on bees from wide-ranging situations. The agency finds that uses of these neonicotinoids have âvarying degrees of effects on bees,â and that some uses âmay pose a risk of concern to bees.â However, instead of a complete ban of the neonicotinoids, the agency is proposing mitigation measures to minimize potential exposure to bees, which includes the phase-out of many uses and certain additional product label statements. Clothianidin will see a phase-out of the following uses: Foliar application to orchard trees and strawberries, and Foliar application to municipal, industrial and residential turf sites. There will also […]

(Beyond Pesticides, June 6, 2018)Â By the close of 2018, three top neonicotinoid (neonic) pesticides, linked to the worldwide decline in bee populations, will be banned for outdoor use in the European Union (EU), based on the General Court of the European Unionâs (GCEU) ruling last month. The GCEU, the equivalent of the U.S. Supreme Court, ruled in favor of taking precautionary action to protect pollinators from clothianidin, imidacloprid, and thiamethoxam. This ruling allows for the limited use of neonic-treated seeds grown in permanent greenhouses where contact with bees is not expected. In its lawsuit, multinational seed and chemical companies, Syngenta and Bayer âmanufacturers of the neonics in questionâ argued unsuccessfully that the pesticides do not necessarily harm bees if farmers use them according to label instructions. Syngenta also sought compensation of approximately $435 million to offset market losses resulting from the ban, but that, too, was denied. In rejecting the arguments of Syngenta and Bayer, the high court aligned itself with the European Food Safety Authority (EFSA) and its assessment of the harm caused by the widely used pesticides. EFSAâs updated assessment, released in February of this year, provided convincing evidence that neonics represent a risk to wild bees and […]

(Beyond Pesticides, March 12, 2018)Â European Regulators Confirm Neonicotinoids Harm Bees, Increasing Likelihood of Continent-Wide Ban A comprehensive assessment released last week by the European Food Safety Authority (EFSA) confirmed that neonicotinoids, the most widely used class of insecticides in the world, pose risks to honey bees and wild pollinators. EFSA analyzed over 1,500 studies from academia, beekeeper associations, chemical companies, farmer groups, non-governmental organizations, and national regulators. EFSAâs risk assessment provides a definitive, independent conclusion that overall, continued use of these chemicals risks the long-term health of pollinator populations. Tell Your Governor to Ban Neonicotinoid Insecticides âThe availability of such a substantial amount of data as well as the guidance has enabled us to produce very detailed conclusions,â said Jose Tarazona, PhD, head of EFSAâs Pesticides Unit in a press release. This is EFSAâs second comprehensive evaluation of the three most commonly used neonicotinoids: imidacloprid, clothianidin, and thiamethoxam. Earlier research finalized in 2013 led the European Union (EU) to ban use of the three neonicotinoids on agricultural flowering crops. The new assessment applies EFSA guidance to assessing risks to bees and on the initial review. It includes literature not only on honey bees, but also on wild pollinators, including bumblebees […]

(Beyond Pesticides, February 16, 2018) U.S. Representatives Blumenauer (D-OR) and Jim McGovern (D-MA) this week announced plans to reintroduce the Saving Americaâs Pollinators Act, (previously H.R. 3040) which suspends the registration of certain neonicotinoid insecticides until the U.S. Environmental Protection Agency conducts a full scientific review that ensures these chemicals do not harm pollinators. Beyond Pesticides joined Rep. Blumenauer and other experts from environmental, conservation, whistleblower and farmworker health groups on Capitol Hill to urge Congress to take action to protect pollinators in the face of ongoing obstruction by an increasingly industry-influenced EPA. âPollinators are the backbone of Americaâs agriculture system. Acting now to protect them and stop their decline is essential to the sustainability of our nationâs food supply,â Rep. McGovern said. âSimply taking the word of the manufacturers that their products are safe is not an option. Consumers need strong oversight. That is why I am proud to join Congressman Blumenauer in demanding the EPA fully investigate the effect that certain harmful pesticides may have on the vitality of our pollinators.â Numerous scientific studies implicate neonicotinoid pesticides as key contributors to the global decline of pollinator populations. EPAâs own scientists have found that neonicotinoids pose far-reaching risks to […]

(Beyond Pesticides, January 4, 2018) Last month, the U.S. Environmental Protection Agency (EPA) released the preliminary ecological (non-pollinator) assessments for the neonicotinoids (neonics); clothianidin, thiamethoxam, dinotefuran, and the terrestrial ecological assessment for imidacloprid, finding that these pesticides pose both acute and chronic risks to aquatic life and birds. Treated seeds are identified as posing the highest dietary risks to birds, confirming previous research that neonics are highly hazardous not only to bees, but to birds, aquatic life, and other non-target organisms. Released December 15, 2017, EPA opened the public comment period for these assessments until February 20, 2018. Along with the risks identified in the assessments, the agency is specially requesting feedback on the benefits of continued use of the neonics in cotton and citrus crops identified in last year’s pollinator assessments as posing risks to honey bees. EPA states, “We believe early input from the public will be helpful in developing possible mitigation options that may be needed to address risks to bees.” This despite evidence of long-term systemic exposures to non-target organisms that support a phase-out of these pesticides. EPA believes that neonicotinoids are crucial for the management of Asian citrus psyllid, an invasive pest that causes citrus greening, […]

(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 âhoney bees (Apis mellifera), bumble bees (Bombus terrestris), and solitary bees (Osmia bicornis)â 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. […]

(Beyond Pesticides, May 11, 2017) On Monday, a federal judge in California ruled that the U.S. Environmental Protection Agency (EPA) violated the Endangered Species Act (ESA) when it issued 59 neonicotinoid insecticide registrations between 2007 and 2012 for pesticide products containing clothianidin and thiamethoxam. The original lawsuit against EPA, Ellis v. Housenger, was filed in March 2013, by beekeeper Steve Ellis and a coalition of other beekeepers and environmental groups, including Beyond Pesticides. The 2013 lawsuit focused on the EPAâs failure to protect pollinators from dangerous pesticides and challenged EPAâs oversight of the bee-killing pesticides, clothianidin and thiamethoxam, as well as the agencyâs practice of âconditional registrationâ and labeling deficiencies. According to George Kimbrell, Center for Food Safetyâs legal director and the lead plaintiffsâ counsel, âThis is a vital victory. Science shows these toxic pesticides harm bees, endangered species and the broader environment. More than fifty years ago, Rachel Carson warned us to avoid such toxic chemicals, and the courtâs ruling may bring us one step closer to preventing another Silent Spring.â The judge presiding over the case rejected claims by pesticide producers and their supporters that the plaintiffs failed to establish a causal link between the pesticides and the […]

(Beyond Pesticides, April 5, 2017) A new study, Occurrence of Neonicotinoid Insecticides in Finished Drinking Water and Fate during Drinking Water Treatment, has detected neonicotinoids, a class of insecticides known for their detrimental effects on bees, in treated drinking water. This marks the first time that these insecticides have been found in water sourced straight from the tap. Federal regulators have not yet addressed safe levels of neonicotinoids in drinking water, so at this point, any detection of these chemicals is cause for concern. The study authors âreport for the first time the presence of three neonicotinoids in finished drinking water and demonstrate their general persistence during conventional water treatment.â Drinking water samples “collected along the University of Iowa treatment train” over a seven week period, May through July, 2016 directly after corn and soy planting, find three neonicotinoids, clothianidin, imidacloprid, and thiamethoxam at levels ranging from 0.24 to 57.3 ng/L (nanogams per liter). The University of Iowa tap water is run through a water treatment plant that uses conventional treatment methods. In contrast, the Iowa City water treatment methods (granular activated carbon filtration) result in substantially lower levels of the neonicotinoids. Additionally, the researchers found that extensive transformation of clothianidin […]

(Beyond Pesticides, January 17, 2017) On January 12, 2017, the U.S. Environmental Protection Agency (EPA) released major risk assessment documents on  pollinator exposure to bee-toxic neonicotinoid insecticides finding no significant risks, despite the large and growing body of science identifying the pesticides’ hazards. In the documents, EPA identifies risks posed to bees by several neonicotinoid insecticides, but suggests that no restriction on uses are imminent. In another decision meant to protect bees from acutely toxic pesticides, the agency is scaling back its original proposal in deference chemical-intensive agricultural interests. EPA’s long awaited pollinator assessments for the neonicotinoids: clothianidin, thiamethoxam, and dinotefuran, much like the 2016 pollinator assessment release for imidacloprid, identifies risks to bees from the agricultural applications (foliar, soil and seed) of these chemicals, including from pesticide drift. Observed effects include decline in worker bees, and subsequent declines in brood and pollen stores in the colony. EPAâs assessments continue to focus on honey bees, with cursory mention of wild, native bees. Once again, the assessments did not consider risks from exposures to contaminated water, guttation droplets, or soil, with EPA stating that, âThe Agency lacks information to understand the relative importance of these other routes of exposures and/or to quantify potential risks […]

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

(Beyond Pesticides, January 12, 2017) Yesterday marked a monumental event in the fight against pollinator declines, as the rusty patched bumblebee became the first bee species to officially be declared endangered by the U.S. Fish and Wildlife Service (FWS). According to FWS, endangered species designations are made when a species is âin danger of becoming extinct throughout all or a portion of their range.â Tom Melius, Service Midwest Regional Director for FWS, stated in a press release that, when it comes to this determination, â[FWSâs] top priority is to act quickly to prevent extinction of the rusty patched bumble bee. Listing the bee as endangered will help [the agency] mobilize partners and focus resources on finding ways right now to stop the decline.â Listed yesterday in the Federal Register, the ruling will go into effect February 10, 2017. This is a victory for environmental groups who have fought to protect the rusty patched bumble bee from widespread threats, such as habitat loss and pesticide use. According to FWS, the rusty patched bumble bee was once widespread across the United States and parts of Canada, but declined dramatically in the 1990s.  Since then, their populations have dwindled and their overall decline is estimated at 91 […]

Dec
(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, July 12, 2016) Canadian environmental organizations sued the  Canadian Pest Management Regulatory Agency (PRMA) last week in a bid to overturn the approval of two neonicotinoid pesticides linked to the decline of honey bees and wild pollinators. The move comes amid growing awareness, action, and scientific evidence linking this widely used class of insecticides to the global decline of pollinator populations. The lawsuit, filed  by Ecojustice on behalf of  The David Suzuki Foundation, Friends of the Earth Canada, Ontario Nature, and the Wilderness Committee, argues that pesticide products containing two neonicotinoids, clothianidin and thiamethoxam, are unlawfully registered in Canada. The groups allege that PMRA failed to ensure that it had the data necessary to determine the environmental risks, particularly those concerning pollinators, posed by the chemicals. âThe PMRA has taken a see-no-evil, hear-no-evil, speak-no-evil approach by repeatedly registering these neonicotinoid pesticides without important scientific information on their risks to pollinators,â said Charles Hatt, staff lawyer at Ecojustice. Under Canadaâs Pest Control Products Act, PMRA must have âreasonable certaintyâ that a pesticide will not cause harm to the environment before it is registered. The groups also note that several thiamethoxam-based products have been registered by the agency for years […]

(Beyond Pesticides, May 2, 2016) A study published online last week has examined the effects of three neonicotinoids (neonics) on bumblebee colonies, from live bee kills to changed sex ratios. Neonics have been widely cited as contributing to  the demise of both managed and wild bee and pollinator populations. They can cause  changes in bee reproduction, navigation, foraging, and even the suppression of bee immune systems. The study, published in Scientific Reports, looked at field-relevant levels (2.5 parts per billion) of imidacloprid, thiamethoxam, and clothianidin, and found compound-specific effects at all levels, including within individual bee cells, individual bees, and whole colonies in semi-field conditions. Given the limitations of laboratory studies and field studies, researchers conducted a semi-field study to try to recreate and represent real world exposure patterns. The neonics were provided to the bees as an optional supply of sugar syrup, but were free to forage and did need to gather pollen in order to grow and raise offspring. Researchers found that imidacloprid and clothianidin displayed abilities to affect neuronal Kenyon cells, which help with learning, memory and multisensory integration. At the whole colony level, thiamethoxam altered the sex ratio, leaving more males than females. Both imidacloprid and […]

Nov
(Beyond Pesticides, November 12, 2015) The U.S. Geological Survey (USGS) recently performed the first-ever study of pesticide residues on native bee populations and found that they are exposed to neonicotinoid insecticides, as well as other pesticides, at significant rates. This study digs deeper into a question  that was previously considered by a researcher who  studied chemical-intensive  apple orchards and linked a steep decline in wild or native bees to the application of pesticides. The USGS study  broadens understanding about the effects of toxic pesticides to native bee species, expanding field research that has principally focused on managed honey bee populations. The study tested for 122 different pesticides including bifenthrin, atrazine and chlorpyrifos, a chemical for which the U.S. Environmental Protection Agency (EPA) recently proposed to revoke all food tolerances in response to  a court-ordered deadline. According to study findings, 72% of bees tested positive for pesticide residues, raising concerns for the potential for unintended pesticides exposures where land uses overlap or are in proximity to one another.  Residues of pesticides found in bees in the study include  thiamethoxam, clothianidin, and imidacloprid, all of which are highly toxic neonicotinoids, a class of chemicals that have been linked to the global […]

Aug
(Beyond Pesticides, August 28, 2015) The European Unionâs food safety agency confirmed Wednesday that foliar spraying of neonicotinoids (neonics), the widely-used bee-toxic insecticides, poses a risk to bees, bolstering previous research that led to a two-year moratorium on the chemicals in the EU. The European Food Safety Authority (EFSA), which guides EU policymakers, said leaf spray containing three neonicotinoid pesticides â clothianidin, imidacloprid, and thiamethoxam â could harm bees. Previous research found that these chemicals pose a risk as seed treatments or granules, which prompted the European Commission to limit their use in  December 1, 2013. The use of the three neonicotinoid substances in seed or soil treatments is prohibited in the European Union for crops attractive to bees and for cereals other than winter cereals except in greenhouses. “They (the EFSA conclusions) confirm that the Commission was correct to take precautionary measures in 2013,” a Brussels-based EU executive said in a statement. Neonicotinoids have been found by  a growing body of scientific literature  to be linked to honey bee and pollinator decline. Recently, a  study  performed by the Food and Environment Research Agency (FERA) in the United Kingdom provides evidence confirming the link between neonicotinoid pesticides and continually increasing […]

(Beyond Pesticides, July 31, 2015) New information has surfaced regarding the role of agrochemical giants Bayer and Syngenta in the United Kingdom (UK)âs recent decision to temporarily allow the use of neonicotinoid seed treatment on oilseed rape crop. A record of the meeting, involving the UK governmentâs expert committee on pesticides (ECP) and industry representatives, had previously been suppressed. The newly released record of the meeting shows that Bayer and Syngenta were the only external representatives asked to answer the ECPâs questions. The emergency use, which has been granted for 120 days, allows growers to use Bayerâs Modesto (clothianidin) and Syngentaâs Cruiser OSR (thiamethoxam). The active ingredients of these products belong to a class of toxic chemicals known as neonicotinoids  (neonics), which have been  linked  to pollinator decline. These pesticides are associated with  decreased learning,  foraging  and navigational ability in bees, as well as increased vulnerability to pathogens and parasites as a result of suppressed bee immune systems. Used widely in agriculture as seed treatment for various crops, foraging bees, in the absence of their native habitat, are exposed to fields of poison where even pollen and nectar are contaminated. In addition to toxicity to bees, neonicotinoids have been shown […]

(Beyond Pesticides, July 24, 2015) An emergency application was approved by the UK Department for Environment, Food, and Rural Affairs (DEFRA) on Wednesday that allows  farmers to use neonicotinoid seed treatment on 5 percent of oilseed rape crop (known as canola in the U.S.) this summer to control a flea beetle infestation. The emergency use, which has been granted for 120 days, allows growers to use Bayer CropScienceâs Modesto (clothianidin) and Syngentaâs Cruiser OSR (thiamethoxam). The active ingredients of these products belong to a class of toxic chemicals knowns as neonicotinoids, which have been linked to pollinator decline. The request was the second one for the National Farmers Union (NFU) after the first request for a nationwide lifting of the two-year moratorium on neonicotinoid use was rejected. The NFU said it was âfrustratedâ at having to put in an application for a smaller area. There have been numerous attempts to shroud the application process in secrecy. DEFRA told its expert committee on pesticides (ECP) to halt its  normal practice of publishing the minutes  of meetings at which the neonicotinoid applications were discussed, in order to avoid âprovoking representations from different interest groups.â Additionally, according to the Guardian, the UK government […]

Apr
(Beyond Pesticides, April 24, 2015) Two new studies reporting on the adverse effects of neonicotinoids on bees were published Wednesday in the journal Nature, adding to a growing body of scientific literature linking the controversial class of pesticides to the global decline in bee populations. The conclusions reached by the two studies find that not only does neonicotinoid exposure result in reduced bee density, nesting, colony growth, and reproduction, but also that bees in fact prefer foods containing neonicotinoid pesticides despite their adverse effects. Neonicotinoids affect the central nervous system of insects, resulting in paralysis and eventual death. These pesticides have consistently been implicated as a key issue in pollinator declines, not only through immediate bee deaths, but also through sublethal exposure that causes  changes in bee reproduction, navigation, and foraging. The science has become increasingly clear that pesticides, either working individually or synergistically, play a critical role in the ongoing decline of honey bees. Pesticide exposure can impair both detoxification mechanisms and immune responses, rendering bees more susceptible to viruses, parasites, and other diseases, and leading to devastating bee losses. In one study, âSeed coating with a neonicotinoid insecticide negatively affects wild bees,â Swedish scientists report that wild bees […]

Mar
(Beyond Pesticides, March 27, 2015) Portland, Oregon is considering a ban on neonicotinoids, a class of insecticides linked to bee deaths, from use on city property. If the measure passes, Portland will join a long list of towns and communities, including Eugene (Oregon), Â Skagway (Alaska), Â and, in Washington State, Thurston County, Â Seattle, and Spokane. Under the proposed ordinance, city officials would not be permitted to use or buy neonicotinoids or similar pesticides on city lands or in city buildings and would urge stores to label products, such as plants and seeds treated with neonicotinoids. The proposal also applies to city contractors. Additionally, the proposed ban on neonicotinoids and neonicotinoid-like insecticides would not apply immediately to two city rose gardens. Officials say the rose midge, a pest, is difficult to eradicate with the insecticide. Instead the city will look for an alternative method using a pilot project at Peninsula Park in North Portland to test alternative non-toxic insecticides. That proposal would be phased in with a deadline of December 2017 to eliminate all neonicotinoid-based products. The proposal cites seven separate bumble bee incidents in Oregon related to the application of neonicotinoids on trees since June 2013, documented by the stateâs Department […]

Mar
(Beyond Pesticides, March 6, 2015) Last Friday, Oregon enacted a new rule which bans the use of four types of bee-killing insecticides, including  imidacloprid, clothianidin, thiamethoxam and dinotefuran, regardless of application method on linden trees and other Tilia species. The four insecticides that are now illegal to spray on Tilia trees are all in the neonicotinoid chemical class which are implicated in pollinator decline, and represents a step forward in protecting bees. However, Tilia trees are not the only route of exposure that bees and other pollinators have to neonics, which are currently applied to fields across the U.S. as seed treatment. The rule comes at the request of the Oregon Department of Agriculture (ODA) following several bee-kill incidents in Oregon since June 2013, when more than 50,000 bumblebees were killed after dinotefuran was sprayed on trees in a shopping mall parking lot in Wilsonville, Oregon.
