(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 neighborâs 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 weekâs 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 applicatorâs 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. MacAlpineâs 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 neighborâs property or allowing the pesticides to drift, […]

(Beyond Pesticides, January 26, 2017) In a startling move that puts independent science at odds with government, the Trump administrationâs U.S. Environmental Protection Agency (EPA) transition team stated on Wednesday that scientists will now face âan unspecified vetting process before sharing their work outside the agency.â However, this kind of review is at odds with EPA’s own scientific integrity policy, which “prohibits all EPA employees, including scientists, managers, and other Agency leadership, from suppressing, altering, or otherwise impeding the timely release of scientific findings or conclusions.” This comes on the heels of an announcement by the administration several days ago issuing scientific grant and hiring freezes at EPA nationwide, along with effectively banning science communications through social media platforms. According to ProPublica, an EPA employee stated that, âHiring freezes happen, but freezes on grants and contracts seemed extraordinary.â These grants are used for financial support to complete environmental testing, remediation and environmental improvement projects across the country. Additionally, on Friday, January 20, after Donald Trump was officially sworn in, he ordered a freeze on all pending regulations from the Obama administration. This included the listing of the rusty patched bumblebee as endangered by the U.S. Fish and Wildlife Service, which had been set […]

(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. Andrewsâ 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, Syngentaâs scientists instead simply graphed average values over time based on their measurements (measurements such as number of bees in a hive, hive weight, number of brood, etc.), and compared […]

(Beyond Pesticides, January 23, 2017) Last week, the U.S. Environmental Protection Agency (EPA)  released its final Biological Evaluations of Three Chemicalsâ Impacts on Endangered Species, which finds that chlorpyrifos and malathion likely have detrimental effect on 97 percent of all species listed and protected under the Endangered Species Act (ESA), while diazinon adversely affects 78 percent. According to EPAâs release on the subject, this is the âfirst-ever draft biological evaluations analyzing the nation-wide effectsâ of these registered chemicals on endangered species after decades of widespread use. The evaluations stem from a legal settlement with the Center for Biological Diversity (CBD) in which CBD sued EPA in April 2014 for its failure to comply with ESA, which requires the agency to carry out consultations with federal wildlife agencies while registering pesticides. According to Nathan Donley, Ph.D., a CBD senior scientist, âWeâre now getting a much more complete picture of the risks that pesticides pose to wildlife at the brink of extinction, including birds, frogs, fish and plants. When it comes to pesticides, itâs always best to look before you leap, to understand the risks to people and wildlife before theyâre put into use. The EPA is providing a reasonable assessment of those risks, many of which can be […]

(Beyond Pesticides, January 3, 2017) A study published in December 2016 in Environmental Contamination and Toxicology, entitled The Effect of Atrazine on Louisiana Gulf Coast Estuarine Phytoplankton, finds that phytoplankton in estuaries in close proximity to agricultural operations are less productive than phytoplankton in an uncontaminated environment. The study examines three different estuaries of the Mississippi river in Louisiana and also evaluates microcosms with different concentrations of atrazine. Phytoplankton, incredibly important to estuary ecosystems and aquatic life, are an integral part of the aquatic food web and ultimately critical to the wild seafood market. As photosynthetic microorganisms, phytoplankton harness the sunâs energy for metabolism and create as a byproduct of photosynthesis dissolved oxygen, which oxygen-breathing sea life require. For the study, the researchers created microcosms, or large containers that are able to closely mimic ecosystems, so that they can observe the effects of independent variables. On average, phytoplankton in the microcosms are less productive at producing chlorophyll a in the presence of atrazine. The microcosm study design is important because it is difficult to separate and measure the effects of chemicals like atrazine in the environment, given the range of potential causes of phytoplankton decline. A variety of factors, like freshwater discharge rates, precipitation, […]

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

(Beyond Pesticides, October 24, 2016) Systemic neonicotinoid (neonic) exposure is associated with reductions in colony size and changes in foraging behavior, according to a recent field study done by a team of scientists at Imperial College London. The senior author of the study, Richard Gill, Ph.D., stated that when neonicotinoid âexposure is relatively persistent and combined with other stressors associated with land use change, they could have detrimental effects at the colony level.â The study, Impact of controlled neonicotinoid exposure on bumblebees in a realistic field setting, assesses the effect of exposure to the neonic, clothianidin, on bumblebee foraging patterns and colony size. Clothianidin was given to 20 buff-tailed bumblebee colonies for five-weeks in a sugar solution at a concentration of 5 parts per billion, an environmentally relevant level of the pesticide. A bumblebee colony census was done before and after the field experiment, where the number of eggs, larvae, pupae, and workers bees were recorded along with the wax and pollen stores in the colony. The researchers found that the clothianidin treated colonies had fewer workers, drones and reproductive female bees compared to the colonies with no exposure. These data add to the growing body of research on sub-lethal […]

(Beyond Pesticides, October 7, 2016) For the first time in U.S. history, the U.S. Fish and Wildlife Service (FWS) has added a group of bees to the list of Endangered Species. FWS published a final rule last Friday that  declares seven species of yellow-faced bees (genus Hylaeus) that are native to Hawaii as endangered. This announcement immediately follows last weekâs news that FWS has proposed listing the rusty patched bumble bee as an endangered species under the Endangered Species Act (ESA). While the decision is great news for these bees and the environmental groups who have fought to protect them, there is still much work that needs to be done, and FWS says that it needs additional time to identify specific areas to be designated as critical habitat for the endangered bees. Further, though FWS has identified many threats to bees, including habitat loss and degradation due to urbanization, and other human activities, the final rule does not specifically point to pesticides. However, there is an overwhelming amount of research demonstrating that neonicotinoid insecticides, working either individually or synergistically, play a critical role in the ongoing decline of bees and other pollinators. Neonicotinoids have been linked to a range of […]

(Beyond Pesticides, October 4, 2016) Chemicals previously used as  inert ingredients in pesticide formulations have been detected in a wide range of North American wildlife species, according to research published in the journal Environmental Science and Technology. The compounds, perfluroalkyl phosphinic acids (PFPIAs), were widely used as anti-foaming agents in pesticide formulations until 2006, when the U.S. Environmental Protection Agency took regulatory action to cancel  their use, citing âhuman health and environmental risks of concern.â However, the chemicals continue to be used today in consumer goods, including carpet cleaning formulas. While scientists did not find what they would consider high concentrations of the chemicals in wildlife, the ubiquity of the detections was found to be most concerning. Researchers detected the presence of PFPIAs in the blood of 100% of animals sampled. This includes northern pike in Montreal, Canada, cormorants from the Great Lakes, and bottlenose dolphins from Sarasota Bay, Florida. “We aimed for diversity: air-breathing versus water-breathing, differences in habitat, different taxonomic groups,” Amila O. De Silva, PhD, coauthor of the study, said to CNN. Part of the reason for the wide range of detection lies with the properties of these chemicals. They are highly stable and resist degradation from […]

(Beyond Pesticides, September 14, 2016) According to a recent study by the U.S. Geological Survey (USGS), high concentrations of dioxins and furans have been detected in tree swallow eggs collected near several sites around the Great Lakes. Other chemicals detected include polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), which were at background levels. The study is part of efforts to clean up a toxic chemical legacy around the Great Lakes, and the researchers believe their results are critical to regulators to assess âbird or animal deformity or reproductive problemsâ The study, âConcentrations and spatial patterns of organic contaminants in tree swallow (Tachycineta bicolor) eggs at United States and binational Great Lakes Areas of Concern, 2010â2015,â used tree swallows to quantify current exposure to organic contaminants across all five Great Lakes including 59 sites within 27  Areas of Concern (AOCs)  and 10 nearby  locations. The Great Lakes Areas of Concern refers to a U.S.-Canada  Great Lakes Water Quality Agreement  (Annex 1 of the 2012 Protocol) that  defines AOCs as “geographic areas designated by the Parties where significant  impairment of beneficial uses  has occurred as a result of human activities at the local level.” An AOC is a location that has […]

(Beyond Pesticides, July 19, 2016) Exposure to common pesticides at levels often found in the environment can have subtle but significant impacts on the behavioral health of fish, amphibians and other aquatic invertebrates. According to researchers at Northern Arizona University, who analyzed data from nearly 40 experiments to reach their conclusion, fish and amphibians swam 35% slower and were 72% less active after pesticide exposure. Chemical Class Type Example Pesticides Carbamates Insecticide Carbaryl, Aldicarb Organochlorine Insecticide DDT, Endosulfan, Chlordane Organophosphates Insecticide Diazinon, Chlorpyrifos Organotins Biocide Tributyltin Phosphonoglycines Herbicide Glyphosate, Glufosinate Pyrethroids Insecticide Permethrin, Bifenthrin, Esfenvalerate Triazines Herbicide Atrazine, Simazine The study, published in Science of the Total Environment, found that the overall effect on aquatic wildlife varied based on the chemical class the animals encountered. While pyrethroids, carbamates, and organophosphates resulted in a significant decrease in swim speed, triazines and phosphonoglycines showed no overall effect. Pyrethroids, carbamates, organophosphates, organochlorines, and organotins decreased activity, while phosphonoglycines had no overall effect, and triazines actually increased activity. âI didnât think that we would see [an effect] across such a wide range of pesticides so consistently, but we did,â said study co-author, Catherine Propper, PhD to KNAU, âand that leads to some concerns about […]

(Beyond Pesticides, June 23, 2016) A truck full of dead bees made its final stop yesterday at a rally outside the headquarters of the U.S. Environmental Protection Agency (EPA), culminating a coast-to-coast tour to raise awareness about recent massive declines in pollinators. While the millions of dead bees stayed on the truck, advocates and beekeepers, including Beyond Pesticides, delivered over 4 million signatures urging an immediate ban on bee-killing pesticides. âIn the five years since I started keeping bees, Iâve seen many hives killed by pesticides,â said James Cook, a Minnesota-based beekeeper who has been driving the truck across the country since last Monday. âIf some fundamental things donât change, itâs going to be really hard for beekeepers to adapt to the environment around us.â Bees pollinate most of the worldâs most common crops, including summer favorites like peaches and watermelon. But over 40 percent of U.S. honeybee hives die each year, costing the farming and beekeeping industry more than $2 billion annually. The most significant culprit in the bee die-off is the widely-used class of pesticides called neonicotinoids, or neonics. Last spring EPA began a process to assess four types of neonics and their impacts on pollinators. In January […]

(Beyond Pesticides, June 17, 2016) The pesticide industry has weakened and delayed pesticide reforms and is shaping new state pollinator âprotectionâ plans nationwide that do little to protect bees, according to a new Friends of the Earth report.  The report is being released in advance of  Pollinator Week (June 20-26, 2016), as people assemble to ask for improved protection for pollinators. The investigation, Buzz Kill: How the Pesticide Industry is Clipping the Wings of Bee Protection Efforts Across the U.S., reveals an array of pesticide industry tactics to slow urgently needed pollinator protection measures at federal and state levels. The report details how new state pollinator protection plans, many still unfinished, have been heavily influenced by pesticide industry interests. According to the report, industry is spending hundreds of thousands of dollars on lobbying to delay state and federal action on the chemicals they manufacture. As a result, state pollinator protection plans across the U.S. are falling short in several ways, including: State pollinator protection plans currently provide more protections for pesticides and pesticide users than for bee keepers and bee colonies. Pesticide industry influence is pervasive throughout statesâ legislative and regulatory planning efforts. Plans lack metrics to measure effectiveness, improvement […]

(Beyond Pesticides, June 14, 2016) To celebrate National Pollinator Week, June 20-26, 2016, several Washington, DC restaurants have teamed up with Beyond Pesticides and the Center for Food Safety to launch a campaign, âMade by Pollinators,â to protect pollinators suffering steep declines. With one out of every three bites of food reliant on bees, the participating restaurantsâ patrons will be treated to a special menu featuring pollinator-friendly food and provided with information on what they can do to help pollinators. The restaurants hope to increase public awareness on the importance of pollinators and steps that can be taken to reverse the decline. Participating  restaurants include Busboys and Poets, Founding Farmers, Lavagna, the Tabard Inn and Restaurant Nora. Of the 100 crop varieties that provide 90% of the worldâs food, 71 are pollinated by bees. Honey bees alone pollinate 95 kinds of fruits, nuts and vegetables, such as apples, avocados, almonds, and cranberries. The value of pollination services to U.S. agriculture alone amounts to nearly $30 billion and about 80% of flowering plants require animal pollination. A recent government survey reports that U.S. beekeepers lost 44 percent of their colonies between spring 2015 and 2016 âthe second highest loss to date. […]

(Beyond Pesticides, June 8, 2016) With years of data documenting the harmful impacts of the herbicide atrazine on aquatic organisms and other wildlife, a recent U.S. Environmental Protection Agency (EPA) assessment now concludes that this widely used chemical poses risks to fish, amphibians, aquatic invertebrates, and even birds, reptiles and mammals. Atrazine is a potent endocrine disruptor with strong associations with birth defects, sex reversal and hermaphroditism in organisms, and whose risk to environmental and human health is exacerbated by pervasive surface, ground and drinking water contamination. Last week, EPA released its triazine ecological risk assessments for atrazine and its chemical cousins simazine, and propazine. The assessments evaluated risks to animals and plants including, amphibians, birds, mammals, fish, reptiles, aquatic invertebrates, aquatic plant communities, and terrestrial plants. Â EPA is currently in the registration review process for these chemicals. For atrazine, EPA concludes, âaquatic plant communities are impacted in many areas where atrazine use is heaviest, and there is potential chronic risks to fish, amphibians, and aquatic invertebrate in these same locations. In the terrestrial environment, there are risk concerns for mammals, birds, reptiles, plants and plant communities across the country for many of the atrazine uses.â Levels of concerns were […]

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

(Beyond Pesticides, May 13, 2016)  Raising questions about Roundup’s (glyphosate) effects on soil health, a study published last month shows that the chemical  is toxic to soil fungus at doses well below levels which are recommended for agricultural use. The commercial formulation of Roundup is  more toxic than technical active ingredient,  glyphosate, highlighting the need to evaluate  full formulation  effects, including  so-called inert ingredients. The study, published in Environmental Science and Pollution Research, looked at Roundupâs effects on  a soil fungus, Aspergillus nidulans. Researchers found that a dilution of Roundup at a rate 100 times less than that  allowed in agricultural production corresponded with 50% mortality of the fungus. A dose only 50 times lower than the recommended application rate for agricultural uses resulted in 100% mortality of the fungus. Even at the median lethal dose (LD50) and lower concentrations, researchers saw impaired growth, cellular polarity, endocytosis and mitochondria (impaired average number, volume and metabolism). The study also found that Roundup has an effect on the soil fungusâ ability to break down nutrients for energy use. Rather than depleting mitochondrial activity, as found in animal cell studies, researchers found a stimulation of mitochondrial activity in the fungal cells, indicating a […]

(Beyond Pesticides, May 11, 2016) Another campus, Macalester College in St. Paul, Minnesota has pledged to become a designated BEE Protective campus. This recognition comes from Beyond Pesticidesâ and Center for Food Safetyâs BEE Protective Campaign, which aims to protect bees and other pollinators from harmful pesticides like neonicotinoids. As part of its  commitment, Macalester College will  no longer use neonicotinoids on its  campus grounds. Neonicotinoids are a class of pesticides known to have severe impacts on bee populations. Macalester is now one of several campuses around the country that have pledged to protect pollinators and move away from using harmful pesticides that are toxic to these beneficial creatures. Just last month,  Antioch College in Yellow Springs, Ohio pledged to become a BEE Protective campus. In addition to these campuses, several local communities and states are also taking a stand for pollinators by passing policies that restrict the use of bee-toxic pesticides. For more on how your campus or student group can support pollinators and become BEE Protective, visit the BEE Protective Ambassadors webpage. âMacalesterâs new resolution to help protect pollinators fits well with our Sustainability Plan and Sustainable Landscaping Master Plan.

(Beyond Pesticides, May 10, 2016) Following an apparent accidental release of documents relating to the safety of the herbicide glyphosate, late last month the U.S. Environmental Protection Agency (EPA) also released and then retracted a preliminary ecological risk assessment of another toxic herbicide, atrazine. Under federal law, every pesticide registered in the United States is required to undergo a 15-year registration review to analyze human health and environmental impacts and determine whether the chemicalâs use should continue another 15 years. The last decade and a half have seen plethora of studies underscoring that atrazine is harmful to human health, and poses unreasonable adverse risks to ecological health, despite attempts by its major manufacturer, Syngenta, to silence and discredit its critics. EPAâs preliminary ecological risk assessment finds that for current uses at prescribed label rates, atrazine may pose a chronic risk to fish, amphibians, and aquatic vertebrate animals. Where use is heavy, the agency indicates that chronic exposure through built-up concentrations in waterways is likely to adversely impact aquatic plant communities. Â Levels of concern, a wonky equation that EPA produces to measure risk, were exceeded for birds by 22x, fish by 62x, and mammals by 198x. Even reduced label rates were […]

(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 […]

(Beyond Pesticides, April 29, 2016) Traces of pesticides, including the long-banned organochlorine chemical DDT, have been found in Western pond turtles, insects, and soil sediment at Sequoia National Park, according to a study.  The study, entitled Organic contaminants in western pond turtles in remote habitat in California  and published in the journal Chemosphere, surveys a suite of 57 current- and historic-use pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in the western pond turtle, along with their potential prey items and habitat. California study sites include Sequoia National Park, Whiskeytown National Recreation Area, and Six Rivers National Forest, all of which are downstream of undeveloped watersheds and varied in distance from agricultural and urban pollution sources. Researchers found that organic pollutants are widespread in the western pond turtle, which has conservation status; that pesticides are prominent in Sequoia National Park, which is downwind of heavy agriculture; and that the legacy  pesticides and PCB concentrations indicate that bioaccumulation is occurring. Brian Todd, Ph.D., an associate professor of wildlife, fish, and conservation biology at University of California Davis, co-authored the study. Dr. Todd said controlling the flow of pesticides into national parks is pretty much impossible. âSequoia National Park is very […]

(Beyond Pesticides, April 25, 2016) Last week, the City Council of Milwaukie, Oregon passed a resolution that halts the use of bee-toxic neonicotinoid insecticides on city government and public property,  joining the growing number of local governments protecting pollinators.  Neonicotinoids  (neonics) have been widely cited in the demise of both managed and wild bee and pollinator populations.  The resolution specifically  restricts city government agencies from purchasing plants and seeds that have been treated with neonicotinoids and other systemic insecticides and urges public and private landscapers and homeowners to plant bee-friendly habitats.  Clackamas County will join with the Mayor’s office and City Council of Milwaukie to adopt an Integrated Pest Management Plan that mirrors the resolution. In addition to these stipulations, the City of Milwaukie is using this resolution to: urge all businesses, homeowners, and homeowner’s associations operating within the City ensure no plants, seeds, or products containing neonicotinoids are purchased, sold, or used within the City; and to clearly and accurately label any plants or materials that have been treated with a neonicotinoid or neonicotinoid-like insecticide; require that commercial pest service providers performing services on behalf of the City provide landscape services that encourage pollinator populations and support pollinator services; […]

(Beyond Pesticides, April 22, 2016) Today is Earth Day! As honey bees and other pollinators continue to suffer from staggering global declines, Beyond Pesticides works year-round through the BEE Protective campaign, launched Earth Day 2013, to support nationwide local action aimed at protecting pollinators from pesticides. Pollinators are a vital part of the environment, a barometer for healthy ecosystems, and critical to the nationâs food production system. With one in three bites of food reliant on bees and other species for pollination, the decline of honey bees and other pollinators demands swift action. The BEE Protective campaign includes a variety of educational materials to help encourage municipalities, campuses, and individual homeowners to adopt policies and practices that protect bees and other pollinators from harmful pesticide applications and create pesticide-free refuges for these critical  organisms. In addition to scientific and regulatory information, BEE Protective also assists people and communities with  a model community pollinator resolution and a pollinator protection pledge. Insecticides, specifically neonicotinoids, have increasingly been linked to bee declines. These chemicals are used extensively in U.S. agriculture, especially as seed treatment for corn and soybeans. Agriculture is not the only concern however, as pesticide applications in home gardens, city parks, […]
