Native Bee Populations on Decline on U.S. Farms

Wednesday, December 23rd, 2015

(Beyond Pesticides, December 23, 2015) Native  bees are on the decline in some of the major agricultural regions in the United States, according to a new study. The study scientists produced the first national map of bee populations and identified numerous trouble areas. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have experienced ongoing and rapid population declines. The continuation of this crisis threatens the stability of ecosystems, the economy, and food supply, as one in three bites of food are dependent on pollinator services. The study, titled Modeling the status, trends, and impacts of wild bee abundance in the United States  and published in the journal Proceedings of the Natural Academy of Science, for the first time aims to assess the status and trends of wild bees and their potential impacts on pollination services across the U.S. and found that between 2008 and 2013 bee abundance declined across 23% of the nation’s  land area. The decline is generally associated with conversion of natural habitats to row crops. The researchers also list pesticide use, climate change, and disease as other threats to wild bees. The researchers specifically cited 139 counties as especially worrisome, with […]

Montreal, Canada Proposes “Complete Ban on Neonics”

Tuesday, December 15th, 2015

(Beyond Pesticides, December 15, 2015) Last week Montreal, the largest city in Canada’s Quebec province, announced plans for an all-out ban on the use of bee-toxic neonicotinoid pesticides. The new regulations represent the strongest move against this neurotoxic class of insecticides by any government entity to date. Environmental and health advocates are praising the ban as a sign that more and more localities in North America are finding these chemicals unnecessary to manage pest problems, and not worth the risk to pollinators and other wildlife. Montreal’s regulations provide for a complete ban, “without exception,” on the use of neonicotinoids outside of buildings on City land. Prior to the new rules, private citizens and businesses could obtain a temporary permit for the use of neonicotinoids in the  case  of an infestation, however, the permit will no longer be available and citizens will be encouraged to employ alternative practices or products. The ban will also apply to golf courses and properties in the City used for agricultural and horticultural purposes. “By adopting a regulation that prohibits the use of such pesticides in Montreal, our Administration places the health of its citizens, the quality of life of its neighborhoods and the preservation of […]

Herbicide (Dicamba) Drift Adversely Affects Non-Target Pollinators and Plants

Thursday, December 10th, 2015

(Beyond Pesticides, December 10, 2015) Researchers at Pennsylvania State University (Penn State) and the Pennsylvania Association for Sustainable Agriculture published a study, which found that aerial drift of the herbicide dicamba adversely affects non-target plants and pollinator species. Dicamba is a chlorinated benzoic acid herbicide associated with neurotoxicity and reproductive effects. The study used alfalfa crops to track the flowering and floral visitation by insects, specifically pollinators, after applications of sublethal doses of dicamba. The researchers concluded, “Our results suggest that widespread non-target damage from these herbicides may adversely affect pollinator communities.” Because dicamba is “frequently responsible for sublethal, off-target damage” to plants and insects, Penn State researchers assessed the most common route of exposure: particle and vapor drift. In its  study, Effects of the Herbicide Dicamba on Nontarget Plants and Pollinator Visitation, the research team examined the crop species alfalfa (Medicago sativa), which requires insect pollination to produce seeds, and the native plant species common  boneset (Eupatorium perfoliatum), which is highly attractive to a wide range of pollinator species. The researchers applied a range of sublethal doses of dicamba to the plants, then tracked flowering and floral visitation by insect species. They identified the types of insects visiting the […]

Home Depot Announces Phase Out of Bee-Toxic Pesticides

Friday, December 4th, 2015

(Beyond Pesticides, December 4, 2015) Home Depot, the world’s largest home-improvement chain, has announced that it will no longer use  neonicotinoid (neonic) pesticides (which have emerged as the leading class of pesticides responsible for bee declines) in  80 percent of its flowering plants, and that it will complete its phase-out in plants by 2018. This follows the announcement made by Lowe’s earlier this year to phase out the sale of products containing neonicotinoid pesticides within 48 months. On its Eco Options gardening page, Home Depot says the following: “Our live goods suppliers have reduced the number of plants that they treat with neonicotinoids, so that now over 80% of our flowering plants are not treated HomeDepotWinBPwith neonicotinoids. We will continue this decrease unless,  1) it is required by state or federal regulation, or  2) undisputed science proves that the use of neonicotinoids on our live goods does not have a lethal or sub lethal effect on pollinators. Otherwise we will have a complete phase-out of neonicotinoid use on our live goods by the end of 2018.” “It’s important that retailers begin to make the switch toward safer products for bees, butterflies, and other beneficial insects,” said Jay Feldman, executive director […]

New Bee-Killing Pesticide Approved in EU

Thursday, December 3rd, 2015

(Beyond Pesticides, December 3, 2015) Last month, the European Commission and member states approved the new pesticide flupyradifurone. The department, known as Directorate-General for Health and Food Safety, authorized the approval of the pesticide, which is an insecticide in  the chemical class  butenolides. Bayer Crop Sciences, the creator of flupyradifurone, touts the insecticide as a “safe” alternative to neonicotinoids (neonics), although both neonics and butenolides are systemic, persistent, and acutely toxic to adult honey bees. Already launched in the United States, Mexico, Nicaragua, Guatemala, Honduras, and the Dominican Republic, advocates are pointing to the hasty nature of flupyradifurone’s approval and the lack of scientific research supporting its use. Flupyradifurone, marketed as “Sivanto prime” in Europe, is approved for use in the EU on sucking pests that feed on fruits and vegetables as well as specialty crops such as hops.  It is also approved for use in seed coatings. The chemical is neurotoxic and can inhibit nicotinic acetylcholine receptors (nAChR) in the nervous system. Neonicotinoids, widely  criticized for their harmful effects on bees,  affect the nervous system in the same way. Matthias Haas, Ph.D., Global Project Manager at Bayer CropScience says, “It combines efficacy and convenience for the grower with excellent […]

Embattled Scientist Receives Prestigious Civic Courage Award

Wednesday, December 2nd, 2015

(Beyond Pesticides, December 2, 2015) On Monday, Jonathan Lundgren, PhD, the U.S. Department of Agriculture (USDA) entomologist suspended by the agency for his work on neonicotinoids, received a prestigious national award for civic courage after  speaking out on his pesticide research despite what he says is the agency’s effort to “suppress” his work. In October 2015, Dr. Lundgren filed a whistleblower complaint  against USDA, citing unprofessional retaliation following the publication of his  study  linking neonicotinoid insecticides to the decline of monarch butterflies. Dr. Lundgren, Senior Research Entomologist and Lab Supervisor for the Agricultural Research Service (ARS), received the Joe A. Callaway Award for Civic Courage, intended to honor those who “at some personal risk, take a public stance to advance truth and justice, and who challenge prevailing conditions in pursuit of the common good.”  This honor comes as Dr. Lundgren is fighting his suspension for publishing research deemed “sensitive” by his USDA superiors. According to USDA, he had made inappropriate remarks in the workplace, and discussed sensitive topics with the press. In September 2014, Dr. Lundgren  filed a complaint  citing  violations of USDA Scientific Integrity Policy with the Scientific Integrity Office and stating that allegations of his misconduct stemmed from […]

Studies Add to Mounting Evidence of Neonic Dangers

Monday, November 30th, 2015

(Beyond Pesticides, November 30, 2015) Last week, two studies were published that link neonicotinoid (neonic) insecticide exposure to detrimental effects in bees and butterflies. The first study, published in the international scientific journal Nature, found that bumblebees exposed to neonics suffered pollination services impairment that reduces their delivery to apple crops. The second study, published in the United Kingdom journal Peer J, used over 1,000 sites cataloged from 1984 to 2012 in the UK Butterfly Monitoring Scheme (UKBMS) database to point to the strong association between neonic use and butterfly population decline. These studies contribute to the mounting evidence that neonic insecticides are linked to pollinator decline. Neonics have increasingly been the subject of recent studies that highlight a causal relationship between neonic exposure  and harmful effects to pollinators, like foraging and reproductive complications. These effects are being identified by scientists all over the world, gradually negating industry criticism of study design. Andre Gilburn, PhD, and ecologist at the University of Stirling, led the butterfly study. He said, “Our study not only identifies a worrying link between the use of neonicotinoids and declines in butterflies, but also suggests that the strength of their impact on many species could be huge.” […]

Quebec to Restrict “High Risk” Pesticides to Protect Pollinators and Public Health

Tuesday, November 24th, 2015

(Beyond Pesticides, November 24, 2015) The Canadian province of Quebec has announced plans for a major overhaul of its pesticide laws in order to protect pollinators, public health and the wider environment. Canadian provinces, particularly Quebec and Ontario, have long led the way in crafting common sense pesticide legislation that responds to sound science on the dangers of these chemicals. The proposed reforms will focus on further restricting the most toxic pesticides allowed for use in both agriculture and residential pest control, including atrazine, chlorpyrifos, and the neonicotinoid class of insecticides, which are  widely implicated in pollinator declines. “QuĂ©bec has made progress in recent years with respect to responsible pesticide management,” said the Quebec Minister of Sustainable Development, Environment and the Fight Against Climate Change. “However, the time is  right to intensify our efforts and become even more proficient at reducing the risks to health and the environment that are associated with pesticide use, particularly by supervising the use of highest-risk pesticides like neonicotinoids, which have a recognized major effect on bee mortality.” Quebec’s Pesticide Strategy 2015-2018  is structured  to incentivize farmers and home gardeners to choose lower risk pesticides through economic motivators such as levies, permits, and compensation fees.

French Researchers Solve Discrepancy in Bee-Killing Neonic Studies

Friday, November 20th, 2015

(Beyond Pesticides, November 19, 2015) French scientists say that they have found the “missing link” between laboratory studies and field studies that assess the adverse effects of neonicotinoid (neonic) insecticides on bees. The study, published in Royal Society Journal Proceedings B, evaluates the effects of neonics on honey bees in field trials. After 15 years of research into the effects of neonicotinoids on bees, researchers had identified a gap between the results of toxicity assessments on individual bees in the laboratory and  impacts seen at the colony level in the field. The new two-year study made two discoveries: First, they found that field exposure to thiamethoxam combined with imidacloprid contamination is associated with a significant excess mortality in individual free-ranging bees.  Second, while colonies appeared to be able to compensate for the excess mortality and preserve population size and honey production, this was done at the expense of a change in brood laying patterns. Thus, this study provides an explanation for the “missing link” in the discrepancies between labs studies and field studies, where the former establishes harmful and fatal effects that had yet to be replicated in real-life conditions. Because the bees responded to the increased mortality with selective […]

Skip the Toxic Turkey This Thanksgiving Season!

Thursday, November 19th, 2015

(Beyond Pesticides, November 19, 2015) Thanksgiving offers an opportunity for family and friends to eat, drink and be thankful for the bounty of the organic harvest. Unfortunately, conventional Thanksgiving meals are more common, which include a host of pesticides, genetically engineered foods, and can affect  the health of consumers and agricultural workers alike. Read below to find out why now, more than ever, it’s important to go organic, and how you can combat the shortcomings of conventional agriculture with an organic Thanksgiving Day feast. Now, more than ever, it’s important to go organic. The most widely used weedkiller, glyphosate, has been classified as a probable carcinogen to humans, based on laboratory animal studies. Glyphosate, produced and sold as Roundup by Monsanto, is touted as a “low toxicity” chemical and “safer” than other chemicals by EPA and industry and is widely used in food production and on lawns, gardens, parks, and children’s playing fields. However, IARC’s recent classification of glyphosate as a Group 2A “probable” carcinogen finds that glyphosate is anything but safe. According to IARC, Group 2A means that the chemical is probably carcinogenic to humans based on sufficient evidence of carcinogenicity in experimental animals. The agency also notes that […]

Native Bees Found to Have Residues of Pesticides Linked to Their Steep Decline

Thursday, November 12th, 2015

(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 […]

USDA Continues to Suppress Independent Science on Bee-Killing Pesticides

Monday, November 9th, 2015

(Beyond Pesticides, November 09, 2015) The U.S. Department of Agriculture (USDA) cancelled a webinar on the presence of neonicotinoids in waterways in the Prairie Pothole region, according to the government watchdog group Public Employees for Environmental Responsibility (PEER). PEER states that the cancellation is “another example of USDA interfering with the release of new science-based information about adverse effects linked to  neonicotinoid (neonics) pesticides.” As a result, PEER continues, “Growing ecological risks posed by the most widely used insecticides in North America will likely not be considered in developing USDA policies, planning or management practices.” Neonicotinoids are a controversial class of chemicals that have been linked to the global bee decline by a rapidly growing body of scientific literature. A webinar, titled Pesticides and Potholes: Understanding the Risks of Neonicotinoid Insecticides to Aquatic Ecosystems in Prairie Canada and Beyond,  was supposed to take place June 24, 2014, according to PEER. Instead, the online event was cancelled by Wayne Honeycutt, Ph.D., the Deputy Chief for Science and Technology at USDA’s Natural Resources Conservation Service (NRCS). The online event would have featured Christy Morrissey, Ph.D., an assistant professor in the University of Saskatchewan, Saskatoon, School of Environment and Sustainability, whose research includes […]

EPA Continues Trend of Pesticide Approval without Adequate Review

Monday, November 2nd, 2015

(Beyond Pesticides, November 2, 2015) The Center for Biological Diversity (CBD) submitted a formal notice last week for intent to sue the Environmental Protection Agency (EPA) for approving benzovindiflupyr, a fungicide that is highly toxic to fish and aquatic invertebrates. CBD asserts that EPA recognized that benzovindiflupyr could harm wildlife and critical habitat protected by the Endangered Species Act (ESA), but approved it for use without consulting with expert wildlife agencies as required by the act. This is  not the first time that EPA has approved toxic chemicals without fully understanding the consequences. On August 28, 2015, EPA granted broad approval for use of benzovindiflupyr on most crops, including cereals, corn, vegetables, fruits, turf grass and ornamentals. The agency’s own data show that benzovindiflupyr is highly persistent in the environment and will build up in waterways due to runoff from treated fields. Nonetheless, EPA approved benzovindiflupyr for immediate use. “This pesticide is highly poisonous to fish and other wildlife, but the EPA approved it anyway,” said Stephanie Parent, senior attorney at the Center for Biological Diversity, in their press release. “This agency’s cavalier approach to approving new toxic chemicals without required consultation or studies must end. The EPA’s indifference is […]

Lawsuit Seeks to Stop Use of Bee-Toxic Pesticide Sulfoxaflor in EU

Wednesday, October 28th, 2015

(Beyond Pesticides, October 28, 2015) On the heels of a recent federal court decision that rejected the U.S. registration of sulfoxaflor, which cited inadequate and flawed review of the science on the chemical’s toxicity to bees, European beekeepers filed complaint that that asks the European Court of Justice to take the same action. The complaint  asks the court to cancel sulfoxaflor’s authorization. Sulfoxaflor is a neonicotinoid-like chemical that, like neonicotinoids, is highly toxic to bees. Three of the most widely used neonicotinoids are currently under a two-year European-wide moratorium which began December 2013, due to concerns about risks to bee populations. European beekeepers, Bee Life European Beekeeping Coordination, the Italian National Beekeeping Union (UNAAPI), and PAN Europe, filed the complaint which cites a published  negative opinion on Dow AgroScience’s sulfoxaflor by the European Food Safety Authority (EFSA). According to EFSA, the pesticide is categorized as ”˜highly toxic to bees’ and it identified crucial toxicity data gaps, which according to the beekeepers, makes a proper risk assessment for bees impossible. Despite these facts, the European Commission’s Directorate-General for Health and Food Safety (DG Sante) and the EU member states authorized sulfoxaflor in July 2015, completely bypassing the pesticide regulation, the complaint […]

Major Popcorn Supplier to Eliminate Neonic Treated Seeds

Monday, October 26th, 2015

(Beyond Pesticides, October 26, 2015) Last week, Pop Weaver, the second largest popcorn supplier in the country, released an official statement on its commitment to “removing 50 percent of its neonicotinoid usage in 2016, 75 percent in 2017, with a long-term commitment of further reducing usage by working with agricultural universities and those companies supplying neonicotinoids to the seed industry.” Widely-used neonicotinoids (neonics), which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies  and by beekeepers  as the major contributing factor in bee decline. This commitment is a response to a campaign led by Center for Food Safety (CFS), which asked citizens to sign a petition asking Pop Weaver, and other large popcorn suppliers, to protect bees and other pollinators by phasing out the use of neonicotinoid-coated corn seed. Over 37,000 people have signed their petition. Americans eat, on average, 17.3 billion quarts of popcorn each year; each American eats about 68 quarts. According to CFS, there are roughly 40 insecticides currently registered for use as an active chemical on popcorn, including 3 bee-toxic neonicotinoid chemicals: clothianidin, thiamethoxam, and imidacloprid. Between  79 and 100 […]

Study Finds Neonics “Severely Affect” Health of Honey Bee Queens

Tuesday, October 20th, 2015

(Beyond Pesticides, October 20, 2015) Exposure to neonicotinoid (neonic) pesticides results in profound negative impacts to the health of honey bee queens, according to an international team of researchers led by Geoff Williams, MD, PhD, at the University of Bern in Switzerland. While most studies to date have investigated how neonics effect the health of individual workers or overall colony fitness, Dr. William’s study, Neonicotinoid pesticides severely affect honey bee queens, is one of the first to focus on the health of honey bee queens. Neither the European Union nor U.S. Environmental Protection Agency (EPA) study the impacts of pesticides on queen health before allowing a pesticide to market. The results of this research are particularly concerning, given widespread anecdotal evidence from beekeepers across the globe that ”˜poor quality queens’ are playing a role in bee declines. To test the impacts of these chemicals on queen honey bees, scientists exposed a sample of 29 queens to field-realistic levels of the neonics  clothianidian and thiamethoxam (1 parts per billion and 4 ppb respectively), and compared them to a population of 28 control queens, which were not treated with neonics. Both groups experienced similar environmental circumstances in terms of food availability, rearing […]

Study Finds Wildflowers Contain More Neonics than Treated Fields

Thursday, October 15th, 2015

(Beyond Pesticides, October 15, 2015) A new study, published in Environmental Science & Technology, has found that wildflowers bordering fields that are treated with neonicotinoids contain a higher concentration of the bee-toxic pesticides than the actual treated fields, pointing out an often overlooked avenue of exposure for bees. Widely-used neonicotinoids, which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies  and by beekeepers  as the major contributing factor in bee decline. The study, titled Neonicotinoid Residues in Wildflowers, A Potential Route of Chronic Exposure for Bees, discovered neonicotinoid insecticides in wildflowers, including Hogweed and Poppy pollen (up to 86ppb and 64ppb, respectively). The study’s authors  found higher concentrations of neonicotinoids in wild flowers in field margins than in Oilseed rape flowers in the adjacent neonicotinoid treated crop — on average 15ppb vs. 3ppb.   They also found that more than 97% of the neonicotinoids being brought into the hive by honey bees are from wildflowers, while only 3% are  from the crop. Researchers have found  that chronic exposure to neonicotinoids increases neuronal vulnerability to mitochondrial dysfunction in the bumblebee. In other words, these pesticides […]

Reno, Nevada Kick-Starts Pesticide-Free Parks Program

Tuesday, September 29th, 2015

(Beyond Pesticides, September 29, 2015) Last week, the City of Reno, Nevada officially approved a Pesticide-Free Parks program aimed at improving the health of its residents and the local environment. In addition to two downtown parks, Neighborhood Advisory Boards within each of City’s five wards chose two parks to join the program, bringing the total to 12 pesticide-free parks. The program is an outgrowth of resident concern over the use of pesticides linked to cancer, asthma, and learning disorders, as well as impacts to local water quality. Beyond Pesticides worked to support the pesticide-free parks movement by sponsoring a training session taught by nationally renowned turfgrass expert Chip Osborne on how to transition to organic practices. “This is a major win for the city in regards to our priority of providing and maintaining safe and healthy neighborhoods,” Ward 2 Reno City Councilmember Naomi Duerr told ABC8. “Community input will continue to drive the important decisions we make.” According to a staff report released by the Reno Department of Parks, Recreation and Community Services, there is not expected to be any burdensome financial implications put upon the City as a result of the program. “There will be no cost implications as […]

Study Finds No Benefit to Bee-Toxic Neonic Use

Friday, September 25th, 2015

(Beyond Pesticides, September 25, 2015) Neonicotinoid-treated seeds do not reduce crop damage from pests, adding to a growing body of evidence questioning the benefits of using these bee-toxic insecticides, according to a study  published in the journal BioOne. Widely-used neonicotinoids (neonics), which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies and by beekeepers  as the major contributing factor in bee decline. The study,  titled Impact of Western Bean Cutworm (Lepidoptera: Noctuidae) Infestation and Insecticide Treatments on Damage and Marketable Yield of Michigan Dry Beans, examines the relationship between western bean cutworm infestation and damage in dry beans, and the use of seeds treated with the neonicotinoid thiamethoxam, as well as soil treated with aldicarb, another systemic insecticide. Researchers have concluded that neither thiamethoxam nor aldicarb reduced cutworm damage. In fact, plots treated with these insecticides had a higher percentage of defects due to feeding by pests when compared to untreated plots, which researchers believed is  attributable to factors such as fewer natural enemies. There have been additional reports and studies published over the past few years questioning the benefits of neonic use. In […]

Sublethal Glyphosate (Roundup) Exposure Harms Bees

Friday, September 18th, 2015

(Beyond Pesticides, September 18, 2015) Glyphosate’s harmful effects continue to accumulate, this time with evidence pointing to toxic and sublethal effects on bees. According to a new study conducted by German and Argentinian researchers, honey bees exposed to low levels of glyphosate have a hard time returning home. Glyphosate, the  controversial and toxic active ingredient in Monsanto’s Roundup, is an herbicide widely used on genetically-engineered (GE) crops as well as on parks and golf courses, for control of weeds and grasses. Along with neonicotinoids, which have been linked to worldwide bee decline by a growing body of science, glyphosate is just another chemical in the toxic mixture that bees and other non-target organisms are constantly exposed to in the environment. In the study, titled “Effects of sublethal doses of glyphosate on honeybee navigation” and published in the Journal of Experimental Biology, researchers evaluate the effects of recommended concentrations of glyphosate used in agricultural settings on honey bee navigation and found that a single exposure to a concentration of glyphosate within this range delays the return of the foraging honey bee to the hive. Flight trajectories were also affected after successive exposure to the herbicide, suggesting that the spatial learning process […]

City of Lafayette, Colorado Restricts Bee-Toxic Neonicotinoids

Thursday, September 17th, 2015

(Beyond Pesticides, September 17, 2015) On Tuesday, the City Council of Lafayette, Colorado unanimously approved a resolution to prohibit bee-toxic neonicotinoid insecticides on city property. The resolution restricts the use of neonicotinoids on any land owned or operated by the city, including public rights-of-way, parks, playing fields, watersheds and ditches, open space lands, and public landscapes. Modeled on  a resolution passed in May by neighboring Boulder city, the new resolution has been propelled through the City Commission with  support from grassroots organizations, including Bee Safe Boulder and Pesticide Free Boulder County Coalition. The resolution affirms that the City of Lafayette: Not purchase or use any neonicotinoid pesticides on city owned or operated land; Restrict city and agricultural contractors from using neonicotinoids like imidacloprid, clothianidin, thiamethoxam, dinotefuran, etc.; Provide exceptions only when emergency situations where the life or health of a valuable, important land asset is at risk, such as a valuable tree or golf course, and when the neonicotinoid application is the most effective option; Urge all residents and business in Lafayette to suspend neonicotinoids for use in seed treatment, soil application, foliar treatment, and other bee-attractive settings; Purchase landscape materials that have not been treated with neonicotinoids and urge […]
