Watchdog Groups Urge Maryland to Better Enforce State’s Pollinator Protection Act

Thursday, January 3rd, 2019

(Beyond Pesticides, January 3, 2019) Bee-toxic pesticides banned for consumer use by the state of Maryland are still being sold in hardware and garden stores, according to reports from beekeeper and consumer watchdog groups. In 2016, Maryland passed the Pollinator Protection Act, which limited the use of neonicotinoids, insecticides implicated in the global decline of pollinator populations, to only certified applicators. According to spot checks by the Maryland Pesticide Education Network (MPEN) and the Central Maryland Beekeepers Association (CMBA), state enforcement agencies still have a ways to go to ensure retailers are complying with the law. From May to October 2018, six volunteers visited 30 Maryland stores along the Baltimore-Washington corridor to see whether they are complying with the law by removing bee-toxic neonicotinoids from retail consumer sale. Eleven of the 30 stores were not in compliance, ranging from local home and garden stores to national big-box chains. “I’ve taken bottles off the shelf and taken them up to an employee or a manager, and said, ‘You really need to stop selling this stuff — it’s illegal,’” said Steve McDaniel, a master beekeeper in Carroll County to the Bay Journal. The state, for its part, indicates that staffing problems at […]

Pollinator Disappearance Documented in Vermont, Confirming Insect Apocalypse

Friday, December 14th, 2018

(Beyond Pesticides, December 14, 2018) The richness, diversity, and abundance of wild bumblebees in Vermont has plummeted over the last century, according to an analysis from researchers at the University of Vermont and Vermont Center for Ecostudies (VCE). This research adds fresh evidence to the growing realization that mankind is witnessing and contributing to, as the New York Times recently labeled, a worldwide insect apocalypse. “We’re losing bumblebees even before we fully understand their benefits to our economy and well-being, or how they fit into ecosystems,” said Kent McFarland, study coauthor and conservation biologist at VCE in a press release. Researchers conducted surveys with the help of 53 trained citizen scientists. Alongside the researchers, these individuals surveyed bumblebee populations through a combination of photos of wild bees and net collections. In total, over 81% of the state’s municipalities were included in the survey, representing all of Vermont pollinator’s biophysical regions. These data, consisting of over 10,000 bee encounters, were then compared to a database of almost 2,000 historical public and private insect collections amassed by researchers. With the first records beginning at 1915, scientists are able to compose a century-long assessment of pollinator populations in Vermont. “These collections are priceless,” […]

Take Action: Protect Biodiversity – Reinstate the Ban of Bee-Toxic Neonicotinoid Pesticides on Wildlife Refuges

Monday, December 3rd, 2018

(Beyond Pesticides, December 3, 2018) In August 2018, the Trump administration announced a reversal of a 2014 U.S. Fish and Wildlife (FWS) decision to ban neonicotinoid insecticides on National Wildlife Refuges. The administration’s action threatens not only pollinators, but contributes to the attack on biodiversity worldwide.  Tell Congress to protect biodiversity by insisting that the ban on neonicotinoid pesticides in wildlife refuges be reinstated. In 2014, FWS announced that all National Wildlife Refuges would join in the phase-out of neonics (while also phasing out genetically engineered crops) by January 2016. FWS “determined that prophylactic use, such as a seed treatment, of the neonicotinoid pesticides that can distribute systemically in a plant and can potentially affect a broad spectrum of non-target species is not consistent with Service policy. We make this decision based on a precautionary approach to our wildlife management practices and not on agricultural practices.” This move was not only intended to protect honey bees that have suffered average losses above 30% since 2006, but also the federally threatened and endangered pollinators that live in National Wildlife Refuges. However, it is not just pollinators who are affected. Recent research has found dramatic drops in overall insect abundance, leading entomologists to speak of an “insect apocalypse.” Various studies have found reductions of up to […]

Multiple Pesticide Residues in Soil Raise Alarm

Friday, November 30th, 2018

(Beyond Pesticides, November 30, 2018) A study published this month in Science of the Total Environment reveals numerous pesticide residues persisting in soil, harming the viability of agricultural lands and increasing risk of off-site contamination. Funded by the Horizon 2020 programme of the European Commission, researchers from the European Diverfarming project at the University of Wageningen in the Netherlands suggest nations urgently reevaluate conventional land use and inputs including water, energy, fertilizers, machinery and pesticides. Researchers decrying the lack of soil protection policies endeavored to determine which pesticides had the highest soil persistence and toxicity to non-target species. Three hundred seventeen surface soil samples were analyzed from 11 European countries. Selected countries were those with the largest amounts of active agricultural land, characterizing six distinct cropping systems. Sampled soils purposefully represented different soil properties and were taken from crops with the highest pesticide use per hectare. Samples were then analyzed for the concentration of 76 pesticide residues. These 76 pesticides were selected as being most often applied on conventional crops. Eighty-three percent of samples contained varying degrees of pesticide residues, with 25 percent showing one pesticide residue and 58 percent showing mixtures of two or more. Only 17 percent of […]

Behavioral Effects in Bumblebees Linked to Neonicotinoid Insecticides

Wednesday, November 28th, 2018

(Beyond Pesticides, November 28, 2018) Recent research out of Harvard University and published in the journal Science has demonstrated some of the mechanisms through which exposures to neonicotinoid pesticides harm bumblebee populations. The study found that exposure to imidacloprid, a neonicotinoid — the most widely used category of pesticides worldwide — directly impacts social behaviors in bumblebees. These behaviors have serious effects on the functioning and viability of bee colonies. In the research experiment, worker bees exposed to imidacloprid exhibited reduced general and nurturant activity, and a tendency to locate themselves at the periphery of the nest. The study noted decreased caretaking and nursing behaviors, which in turn harms productivity and thermal regulation in the colony. These tasks are important to colony development; impaired thermoregulation negatively affected the bees’ typical construction of an insulating wax canopy for the nest, and poor caretaking can affect brood growth. Investigators noted that, “Neonicotinoids induce widespread disruption of within-nest worker behavior that may conribute to impaired growth. . . . These changes in behavior acted together to decrease colony viability, even when exposure was nonlethal.” The authors also observed that many of these dysregulated behaviors were more pronounced at night than during sunlight hours, and […]

Neonicotinoids Found to Change Frog Behavior

Thursday, November 15th, 2018

(Beyond Pesticides, November 15, 2018) Neonicotinoids are widely known for their link to declining pollinator populations, but new research finds that the ill effects of these chemicals also extends to amphibian populations. In a study published late last month, scientists from the National Wildlife Research Center in Ottawa, Canada found that chronic exposure to real-world levels of the neonicotinoid imidacloprid limits the ability of juvenile wood frogs to escape a predator attack. This research adds additional evidence that neonicotinoids are harming aquatic food chains, and reinforces calls for U.S. regulators to follow the science and adequately restrict these toxic pesticides. Researchers investigated the impact of neonicotinoids on the post-tadpole life stage of wood frogs, which has been identified as critical to sustaining viable populations of the species. Rather than determine acute impacts that assess how lethal a pesticide is, scientists opted to observe how wood frog behavior changes as a result of chronic, real-world exposure scenarios. In particular, scientists sought to figure out whether exposure resulted in an altered behavioral response to the presence of a predator. As tadpoles, wood frogs were chronically exposed to real world levels of imidacloprid (1, 10, and 100 micrograms/liter), while others were left unexposed […]

Monarch Population Loss Tallied at 80% since 2005

Wednesday, November 14th, 2018

(Beyond Pesticides, November 14, 2018) Monarch butterflies are in the midst of a staggering decades-long population decline that has rapidly accelerated since 2005, research published by an international team of scientists and the University of Florida last month indicates. According to data meticulously collected by researchers, monarchs making their way to central Florida after emerging from their breeding grounds in Mexico have declined by 80% over the last decade and a half. This is roughly the same time frame at which beekeepers began to see precipitous declines in managed honey bee colonies. Researchers point to industrial development and increasing pesticide use as factors that have accelerated the decline of this iconic species. “A broad pattern is that 95 percent of corn and soybean products grown in the U.S. are Roundup Ready crops that resist glyphosate,” said study coauthor Earnest Williams, PhD, of New York’s Hamilton College in a press release. “That has a national impact. What’s really needed are patches of native vegetation and nectar sources without pesticides. It’s not just for monarchs but all pollinators.” Beginning in 1985, renowned monarch expert Lincoln Brower, PhD and his team monitored monarch populations at a pesticide-free cattle pasture south of Gainesville, FL.

Bumblebees Shown to Suffer Reproductive Failure after Pesticide Exposure

Thursday, November 1st, 2018

(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 “reproducers,” 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 study’s 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 […]

Bees’ Medicine Chest Should Include Sunflower Pollen, Study Finds

Thursday, October 25th, 2018

(Beyond Pesticides, October 25, 2018) A study published last month in Scientific Reports finds that eating sunflower pollen significantly reduces protozoan infection in bumblebees. Studying ecosystem services and what she calls “floral rewards,” evolutionary ecologist Lynn Adler, Ph.D. at the University of Massachusetts Amherst says sunflowers may provide a long sought after solution for improving bees’ immune system response to both disease and parasites. The researchers studied the protozoan Crithidia bombi, a common parasitic infection of bumble bees, known to impair learning and foraging, shorten lifespan and destabilize colony hierarchies by impacting queen bee behavior. From the outset of the study, Dr. Adler says, “the more sunflowers were grown at the farm, the lower the Crithidia load for the bees at that farm.” Knowing pollinators eat pollen as a source of protein and healthy fats, Dr. Adler hypothesized that both pollen and nectar might have medicinal effects against disease and parasites. However, her experiment did not show consistent results with nectar. After bees in the lab were starved for 4-6 hours, researchers fed individual worker bees from small colonies a drop of fructose fluid containing 6,000 Crithidia cells, being the approximate concentration bees may encounter in the wild while foraging. After […]

EPA Considers 300,000-Acre Expansion of Bee-Toxic Pesticide

Friday, October 19th, 2018

(Beyond Pesticides, October 19, 2018) Pollinator advocates and the Center for Biological Diversity (CBD) are imploring the U.S. Environmental Protection Agency (EPA) to deny Bayer CropScience’s application for use of “Sivanto,”a pesticide product with the active ingredient flupyradifurone, a chemical the company claims is safer for bees, but poses the same risks at the notorious bee-toxic neonicotinoid insecticides. If approved, Sivanto would be sprayed in tobacco-growing states along 300,000 acres in the southeast U.S., areas home to more than three dozen species protected under the Endangered Species Act (ESA). Bayer’s proposal for expanded uses comes after EPA’s own assessment indicated risks to endangered species, and despite the fact that the agency has not undergone an ESA mandated consultation with federal wildlife agencies. For the countless flying insects, birds, and bats already under significant threat from neonicotinoids, adding another systemic insecticide to the mix will only make the situation worse. Bayer AG is characterizing flupyradifurone as being harmless to honeybees. However, flupyradifurone, being a systemic pesticide, can negatively impact many non-target species.  In fact, flupyradifurone impacts honey bee brains in a similar way to neonicotinoids, as it impairs learning, memory and the honey bees’ affinity for nectar rewards. Advocates worry that growing […]

Take Action: Tell Kroger to Stop Selling Food Grown with Toxic Pesticides

Monday, October 15th, 2018

(Beyond Pesticides, October 15, 2018) As a leader in organic sales, it is critical that Kroger take additional expedited steps to increase the market share of organic food and eliminate the use of toxic pesticides harmful to public health and the environment. Kroger is among the major food retailers that sells food that has been grown with toxic pesticides, such as the extremely hazardous insecticide chlorpyrifos which causes neurological and brain damage in children. Kroger should immediately end its misleading and fraudulent advertising and labeling of food products as “natural” and replace these with certified organic products. In fact, by misleading consumers with “natural” labeling and advertising of food, Kroger supports chemical-intensive agriculture that poisons children, causes cancer, and threatens biodiversity through the use of toxic chemicals like chlorpyrifos, glyphosate, and neonicotinoids. This is unnecessary and unacceptable. Tell Kroger to stop selling food grown with toxic pesticides. Chlorpyrifos  is a highly neurotoxic organophosphate pesticide that is linked to neurologic developmental disorders in children. Exposure to even low levels of organophosphates like chlorpyrifos during pregnancy impairs learning, changes brain function, and alters thyroid levels of offspring into adulthood. EPA’s own assessment finds that children exposed to high levels of chlorpyrifos have developmental delays, attention problems, attention-deficit/hyperactivity disorder […]

Shareholders Urge General Mills to Stop Pesticide Use in Its Supply Chain, Popular Products

Wednesday, October 10th, 2018

(Beyond Pesticides, October 10, 2018) Nearly one-third of General Mills shareholders called on the company last month to improve product stewardship and eliminate pesticides like bee-toxic neonicotinoid insecticides or the probable carcinogenic weed killer glyphosate from its supply chain. The proposal was put forward by nonprofit organization As You Sow, and Green Century Equity Fund (GCEF), a mutual fund. This is the latest public shareholder action GCEF has made in regards to corporate pesticide reform, with the company previously putting pressure on the Dr. Pepper Snapple Group for its allowance of pesticides within its supply chain. While the actions are encouraging, some advocates are urging shareholder groups to go beyond increased accountability and transparency and push companies to focus on sourcing organic to ensure that no pesticides make their way into food products. The shareholder proposal ultimately garnered support from 31% of General Mills shareholders. “Shareholders believe the company can, and should, do more to protect the health of their supply chain and the public from toxic pesticides,” said Christy Spees, environmental health program manager at As You Sow to the StarTribune. The proposal states, “While the company asserts that it is currently ‘document[ing] continuous improvement’ concerning environmental impacts from its supply […]

Over 60 Local Officials Call on Congress to Protect Local Authority to Restrict Toxic Pesticides in the Farm Bill

Thursday, September 13th, 2018

(Beyond Pesticides, September 13, 2018) House proposal would wipe out communities’ power to restrict pesticides. In an effort to protect the rights of communities nationwide, over 60 local officials from across the country sent a letter to Congress today opposing a farm bill provision that takes away local governments’ authority to restrict hazardous pesticides. The signatories are urging the farm bill conference committee to reject a “poison pill” rider that will preempt local governments, making the entire legislation unacceptable. Section 9101 of the House version of the farm bill will institute federal preemption of local pesticide policies, a move that will overturn a decades-old Supreme Court decision and prevent communities from adopting protective laws that meet the needs of their residents or unique local environment. The letter urges the conference committee to reach an agreement on a final 2018 farm bill that does not include this rider. It was signed by over 60 local officials in 39 communities from 15 different states, ranging from North Miami, FL to South Euclid, OH, West Hollywood, CA and Maui, HI. The County Council of Montgomery County, MD, which passed a landmark policy on toxic pesticides, also sent a letter to the farm bill conference committee. […]

Amsterdam Leads Bee Recovery Efforts by Banning Bee-Toxic Pesticides, Improving Habitat

Wednesday, September 12th, 2018

(Beyond Pesticides, September 12, 2018) The city of Amsterdam, Netherlands is leading global bee recovery efforts by increasing its diversity of wild pollinator species, according to reporting and an analysis by NBC News. A new map published by the city identified 21 bee species not found in an earlier 1998 survey recorded by Amsterdam officials. The increase has been attributed to a range of pollinator-protective measures, including a ban on bee-toxic pesticides and the planting of native flowers, prioritized by the city government since the turn of the century. Local communities throughout the world can look to Amsterdam for policies and practices that will safeguard their own unique pollinator populations. The NBC News report notes several initiatives undertaken by the Amsterdam government. Many of these measures come out of a $38.5 million fund aimed at broadly improving environmental sustainability. “Insects are very important because they’re the start of the food chain,” said Geert Timmermans, an Amsterdam ecologist to NBC News. “When it goes well with the insects, it also goes well with the birds and mammals.” Insect and bee hotels are often installed in conjunction with the development of green roofs, which are encouraged for all new buildings. And parks […]

Study Finds Bumblebees Increasingly Attracted to the Pesticides that Kill Them

Friday, August 31st, 2018

(Beyond Pesticides, August 31, 2018) Given the choice to forage on untreated or pesticide-contaminated food sources, bees will increasingly choose the pesticide, according to research published in Proceedings of the Royal Society B in late August. The data indicate that risks to pollinators grow, rather than wane, over time, making improved regulation over bee-toxic neonicotinoid pesticides even more climacteric. In essence, the study indicates that bees may be undertaking the human equivalent of chain-smoking themselves to death. Authors of the study note that numerous studies have been performed that subject bees to neonicotinoid-treated food, however this research generally allows pollinators to only forage on contaminated sources. While this provides important information on hazard criteria, it does not indicate risk of exposure. Positing the idea that pollinators may eventually seek to avoid neonicotinoid-contaminated nectar, researchers provided bumblebee colonies with a choice over the course of 10 days. At the start, the bees exhibited no discernable preference between toxic and nontoxic food. However, as time went on more and more bees fed from nectar laced with thiamethoxam, a widely used neonicotinoid. By the end of the experiment, food containing 2 parts per billion of the pesticide was eaten 10% more than in […]

Pesticides Contribute to Bird Declines, Threatening Forests, Crops, and Ecological Balance

Monday, August 27th, 2018

(Beyond Pesticides, August 27, 2018) Beyond the visual and audial charms of some bird species, insect-eating birds play a significant role in controlling pests that can ruin crops or ravage forests. A meta-study by Martin Nyffeler, Ph.D. of the University of Basel in Switzerland finds that globally, birds annually consume 400-plus million metric tons of various insects, including moths, aphids, beetles, grasshoppers, crickets, and other arthropods (invertebrate organisms with exoskeletons, paired and jointed appendages, and segmented bodies, such as insects, crustaceans, and spiders). This research reviews 103 studies that examine the volume of insects consumed by various birds in seven of the world’s major biomes. In consuming such volumes of insects that can inflict damage on crops, trees, and other plants on which organisms may feed or otherwise depend, birds provide significant services to ecosystems, to denizens of habitats, and to human food system and economic interests; they also keep local ecosystems in balance. Threats to birds — and thus, to those ecosystem services — include those from pesticide use. Of the 10,700 known bird species distributed across the planet, more than 6,000 are primarily insectivorous. The study indicates that forest-dwelling birds consume the majority of insects (approximately 300 million metric […]

Canada Proposes to Phase-out Pesticides Linked to Bee Decline, Aquatic Risks

Monday, August 20th, 2018

(Beyond Pesticides, August, 20, 2018) Health Canada’s Pest Management Regulatory Agency (PMRA) has announced a plan to phase out the outdoor use of two neonicotinoid insecticides — thiamethoxam and clothianidin — over three to five years, due to concerns about their effects on aquatic invertebrates. This comes after their 2016 proposal to phase out another neonicotinoid, imidacloprid, for the same concerns, but the proposal has not been finalized. In April, the European Union (EU) voted to ban the most widely used neonicotinoids, citing risks to bees. Earlier this year, PMRA proposed to phase out a number of uses of neonicotinoids in order to mitigate risks to pollinators. And now, after the Canadian agency initiated a special review based on a preliminary analysis of available information on the concentrations and frequency of detection of clothianidin in aquatic environment, the agency has proposed another round of phase-outs. The agency’s review focused on assessing potential risk to aquatic invertebrates exposed to clothianidin applied as a seed, foliar or soil treatment. The assessment finds that, in aquatic environments in Canada, clothianidin and thiamethoxam are both being measured at concentrations that are harmful to aquatic insects. These insects, according to the agency, are an important part of […]

Massachusetts Pollinator Advocates Vow to Advance Protections after Legislature Fails to Restrict Neonicotinoids

Thursday, August 9th, 2018

(Beyond Pesticides, August 9, 2018) Last week, the Massachusetts legislature failed to pass legislation that would have restricted the use of neonicotinoid pesticides in the state in order to protect sensitive pollinators, but advocates vow to campaign for a victory in the next legislative session. H. 4041, would have restricted neonicotinoid uses to certified applicators only. Massachusetts beekeepers lost 65 percent of honey bee hives this year, a rate 25 percent higher than the national average. H. 4041, An Act to Protect Massachusetts Pollinators, introduced in 2017, failed to make it to the floor before the end of the legislative session, which ended July 31. The bill gained the support of more than 100 Massachusetts scientists and academics who sent a letter to the Joint Committee on Environment, Natural Resources and Agriculture in support. Over 180 scientists, businesses, beekeepers, farmers, and conservationists formally endorsed this bill to restrict neonicotinoid use to licensed applicators. The Massachusetts County Beekeepers Association worked to organize an extensive grassroots advocacy movement in support of the bill. H.4041 would have placed “common-sense” restrictions on unlicensed use of neonicotinoids. It would require neonicotinoids to be used by licensed or certified applicators, and would also limit the use […]

Trump Administration Reverses Ban of Bee-Toxic Pesticides on National Wildlife Refuges, as California Confirms Neonicotinoid Pesticides Harm Bees

Tuesday, August 7th, 2018

(Beyond Pesticides, August 7, 2018) At the same time that a new analysis by California’s Department of Pesticide Regulation (DPR) finds current neonicotinoid uses in the state expose bees to residue levels known to cause harm, the Trump administration has reversed a 2014 U.S. Fish and Wildlife (FWS) decision to ban neonicotinoids on National Wildlife Refuges. In 2014, newly passed state legislation required DPR to study the impacts of neonicotinoids (imidacloprid, thiamethoxam, clothianidin, and dinotefuran) and adopt control measures to protect sensitive pollinator health within two years. In its report, released last month, DPR finds the highest risk to bees is posed by use of two neonicotinoids, thiamethoxam and clothianidin, on cereal grains like corn, wheat, rice, and barley. The seeds of these crops are typically coated with neonicotinoids before planting, where residues persist in the pollen and nectar. Although these findings are not surprising and have been documented in the scientific literature, California’s analysis indicates neonicotinoids can cause much broader harm, including to pollinators commonly found on many types of vegetables, cereal grains, tree nuts, fruits and tobacco. Shortly after a decision in the Pacific Region, FWS announced that all National Wildlife Refuges would join in the phase-out of neonics (while also phasing out genetically […]

Suburban Bees Still Vulnerable to Neonicotinoids Despite EU Ban

Wednesday, August 1st, 2018

(Beyond Pesticides, August 1, 2018) According to new research from the University of Sussex, bees living in suburban habitats are still being exposed to high levels of neonicotinoid pesticides. Even though there is a European Union (EU) ban on these chemicals, the ban focuses on agricultural and not residential applications. The study’s authors are urging gardeners to forgo the use of these pesticides in favor of more holistic, pesticide-free approaches. The authors of the study say it is the first of its kind to highlight the risk to bees in urban areas posed by garden use of pesticides. Entitled Monitoring neonicotinoid exposure for bees in rural and peri-urban areas of the UK during the transition from pre- to post-moratorium, the study sampled pollen and nectar from bumblebee colonies in rural and peri-urban habitats in three UK regions–Stirlingshire, Hertfordshire, and Sussex over three years. Sampling began prior to the ban (2013), during the initial implementation when some seed-treated winter-sown oilseed rape was still grown (2014), and following the ban (2015). Honey bee colonies in rural habitats were also sampled to compare species-level differences between bumblebees and honey bees. Not surprisingly, the researchers find pesticide contamination in more than 50 percent of the samples, […]

Presence of Neonic Insecticides in Wild Turkeys Highlights Widespread Contamination of the Environment

Thursday, July 12th, 2018

(Beyond Pesticides, July 12, 2018) Neonicotinoid insecticides have become notorious for their impacts to insect pollinators like bees and butterflies, but research finding the presence of these chemicals in wild turkeys is raising new concerns about the ubiquitous nature of these chemicals once released into the environment. Published in Environmental Science and Pollution Research by a team from the University of Guelph (UG), this new study highlights the broader effects of neonicotinoids on wildlife, and underlines calls to restrict the use of these products in favor of a more sustainable pest management approach. Looking at roughly 40 wild turkeys in southern Ontario, researchers found 10 that contained pesticide residue in their livers. Claire Jardine, PhD, pathobiology professor and study co-author notes that wild turkeys in agricultural regions are more likely to be contaminated. “Wild turkeys supplement their diet with seeds from farm fields,” she indicated in a press release. The agrichemical industry coats a majority of corn and soybean seeds with neonicotinoids prior to planting. Because of their systemic nature, neonicotinoids are incorporated the seedlings as they grow, with the promise by the industry that this will alleviate pest pressure.

Regenerative Farms Yield Soil Health and Higher Profits than Chemical-Intensive Operations

Wednesday, July 11th, 2018

(Beyond Pesticides, July 11, 2018) Ecologically-based farming systems contain far fewer pests and generate much higher profits than their conventional, chemical-based counterparts according to research published in the journal PeerJ earlier this year by scientists at South Dakota State University and the Ecdysis Foundation. The study supports calls to reshape the future of agriculture, as ‘regenerative’ farms, which avoid tillage and bare soil, integrate livestock, and foster on-farm diversity. These farms are found to represent an economically viable alternative to overly simplified, pesticide and fertilizer-dependent cropping systems. Given the study’s focus on corn cropping systems, such a shift is possible for thousands of farmers throughout the United States. Researchers looked at roughly 75 fields on 18 farms, measuring the organic matter in the soil, insect pest populations, corn yield as well as profit. Farms using pesticide treatments, which in corn fields is represented primarily by the use of neonicotinoid-coated seeds, had 10x higher pest levels than regenerative farms. As noted in the study, pest populations are a function of the biodiversity within the crop field. Biodiveristy increased on regenerative farms not only because farmers sprayed fewer pesticides, but because they also allowed more plants to grow in between rows. More […]

Kroger Sets 2020 Phase-Out of Bee-Toxic Pesticides on Its Plants, Costco Encourages Suppliers to Change; Both Commit to Carry More Organic

Friday, June 29th, 2018

(Beyond Pesticides, June 29, 2018) It is widely known that pollinators are in trouble. In light of this, Kroger (which includes numerous other grocery chains, like Harris Teeter) announced in a press release last week — during National Pollinator Week —  a phase-out by 2020 of live garden plants treated with the insecticides most closely associated with the decline of bee populations, the neonicotinoids. In May, Costco updated its pollinator policy, which “encourages” its suppliers of garden plants, fruits, and vegetables to limit the use of bee-toxic pesticides and adopt ecological practices. The company in 2016 announced a policy to encourage suppliers to change their pesticides. In a statement that has broad implications for pollinator and environmental protection, Kroger included the following statement about organic food in its press release: “Kroger also offers one of the largest organic produce departments in America, which is desirable for customers looking to minimize potential exposure to synthetic pesticides. Representing nearly 20 percent of America’s annual organic produce business, Kroger sales reached $1 billion in 2017. A dedicated procurement team partners with more than 300 organic produce growers and suppliers every year to bring customers a growing selection of organic fruits and vegetables.” Costco is also […]
