(Beyond Pesticides, May 24, 2024) Even allegedly “low-toxicity” pesticides such as flupyradifurone (insecticide), azoxystrobin, and difenoconazole (fungicides) pose adverse health effects to solitary ground-nesting squash bees (Xenoglossa pruinose), according to a study published in Biological Sciences. Fungicide exposure led to less pollen collected per flower, while exposure to flupyradifurone (FPF) produced larger offspring (which make it more challenging for them to fly). Simultaneous exposure to the three pesticides “induced hyperactivity in female squash bees relative to both the control and single pesticide exposure, and reduced the number of emerging offspring per nest compared to individual pesticide treatments.” With United Nations Food and Agriculture Organizations-sponsored World Bee Day earlier this week, now more than ever advocates are calling for the elimination of toxic insecticide classes, such as neonicotinoids and butanolides, and their wholesale replacement with organic land management principles. This study was written by Sabrina Rondeau, PhD, postdoctoral Fellow in the Department of Biology at the University of Ottawa, and Nigel E. Raine, PhD, professor at University of Guelph’s School of Environmental Science. Published on March 20, 2024, the researchers delve into the individual and co-exposure impacts of two fungicides and one insecticide, which is important, given the documented synergistic effects […]

(Beyond Pesticides, October 9, 2020) A new study demonstrates that emerging “novel” insecticides can cause significant, sublethal harm to beneficial organisms at typical “real life” exposure levels. As neonicotinoid insecticides have come under fire for their terrible impacts on a broad variety of beneficial insects — including their major contributions to the decline of critical pollinators — more such “novel” pesticides are being brought to market in response. The study results, the co-authors say, “confirm that bans on neonicotinoid use will only protect beneficial insects if paired with significant changes to the agrochemical regulatory process. A failure to modify the regulatory process will result in a continued decline of beneficial insects and the ecosystem services on which global food production relies.” Beyond Pesticides would add that the study outcome points, yet again, to the grave recklessness of the pervasive “addiction” to chemical pesticides in agriculture. The solution to this chemical morass is known, doable, and scalable: a transition to organic, regenerative agricultural practices that get everyone off the “toxic treadmill.” Neonicotinoid pesticides (neonics) are the class of chemical pesticides most commonly used worldwide, both on crops and as seed treatments. They are systemic, meaning they infiltrate all tissues of a […]

(Beyond Pesticides, June 23, 2020) Next-generation systemic insecticides, billed by the agrichemical industry as “safer for bees” than neonicotinoids, have been found to stress and kill honey bees. As reported, a study by researchers at Oregon State University in the journal PLOS One, sulfoxaflor and flupyradifurone (in the products Transform and Sivanto, respectively) were found to increase apoptosis (cell death) and increase oxidative stress in exposed honey bees. The study indicates that, “With the recent Environmental Protection Agency (EPA) approval for use of both flupyradifurone and sulfoxaflor, and with the growing concern regarding pollinator health, it is important to better understand any potential negative impacts (especially sub-lethal) of these pesticides on bees.” However, this statement begs the question ‘why these two new bee-toxic pesticide were approved by EPA in the first place.’ This process is familiar and frustrating to those who continue to fight against the decline of pollinators: the chemical industry introduces and EPA approves new toxic pesticides marketed as “safer” to the specific problem caused by its older products, only to find out through independent and academic research that the problem is not solved in the least. Researchers conducted two exposure assessments: one six-hour long study, and another […]

(Beyond Pesticides, March 4, 2019) Last week, U.S. Representative Earl Blumenauer (D-OR) reintroduced the Saving America’s Pollinators Act (H.R.1337) to cancel specific bee-toxic pesticides and establish a review and cancellation process for all pesticides that are potentially harmful to pollinators. The specific pesticides targeted in the bill include the systemic insecticides imidacloprid, clothianidin, thiamethoxam, dinotefuran, acetamiprid, sulfoxaflor, flupyradifurone, and fipronil. The bill also establishes requirements for review of other potentially bee-toxic chemicals by an independent pollinator protection board, and requires annual reports on the health and population status of pollinators. The bill creates a sustainable model for pollinator protection in the face of ongoing obstruction by an increasingly industry-influenced EPA. There are 29 cosponsors to date. The current bill is the fifth version of Saving America’s Pollinators Act (SAPA), which was first introduced by U.S. Representative Conyers (D-MI) in 2013. The newest version differs from previous bills in its bold definition of who should have responsibility for assessing harm to pollinators. SAPA 2019 calls for the establishment of a Pollinator Protection Board, to be composed of expert scientists, beekeepers, farmers, members of environmental organizations and other key stakeholders, nearly all of whom must not have any conflict of interest or affiliation […]

(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 […]

(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 […]

(Beyond Pesticides, January 28, 2015) Global decline of pollinators and pollination services will have a devastating impact on the nutritional health of people in developing countries, especially women and children, if left unabated, according to a new study from scientists at the University of Vermont and Harvard University. This research is the first to examine how pollinators influence nutrient intake and the risk of nutrient deficiency. It also comes at a time when policy makers are slow to find long-term sustainable solutions to reversing pollinator declines, despite mounting scientific evidence urging immediate action. Pollination services are valued at over $125 billion globally and pollinators are responsible for one in three bites of food we eat. However, pollinators like honey bees, wild bees, butterflies and others are in decline around the globe, with many beekeepers, scientists, and environmental activists singling out pesticides as a major contributing factor. But despite suggestions that pollinators are critical not only for global food supply, but specifically human nutritional health, there has not been any research to support this claim until now. The study, “Do Pollinators Contribute to Nutritional Health,” published in PLoS ONE, combined data on crop pollination requirements, food nutrient densities, and actual human […]

(Beyond Pesticides, January 26, 2015) Last week, the U.S. Environmental Protection Agency (EPA) announced it completed the registration of a new pesticide, flupyradifurone, that would be marketed as an alternative to neonicotinoid pesticides, and “safer for bees.” A closer look at this chemical reveals that the agency is grossly misleading the public on the ecological safety of flupyradifurone since the chemical is systemic, persistent, and highly acutely toxic to adult honey bees. At a time when bees are declining, advocates say it is inappropriate for EPA to introduce yet another bee toxic chemical to the market. Flupyradifurone (“Sivanto”) is a new systemic, butenolide insecticide from Bayer CropScience that is to be used on crops such as citrus, cotton, potatoes and many others, and also as seed treatment. Note: EPA is still considering soybean seed treatment. The chemical is a neurotoxic insecticide that can inhibit nicotinic acetylcholine receptors (nAChR) in the nervous system. Neonicotinoids, widely linked to devastating health impacts on bees, affect the nervous system in the same way. However, EPA states that flupyradifurone differs from neonicotinoids because of the way it binds to the receptors and is metabolized. However, most troubling is that, based on EPA’s registration documents, the […]

(Beyond Pesticides, November 7, 2014) Environmental organizations are calling on the Canadian government to reject the approval of yet another bee-killing pesticide called flupyradifurone. According to Health Canada’s Pest Management Regulatory Agency (PMRA) —responsible for regulating pesticides in Canada— the new pesticide exhibits systemic behavior and “may pose a risk to bees, non-target beneficial arthropods, and freshwater and saltwater invertebrates when used for foliar application.” Additionally, the pesticide “may pose a risk to birds and small wild mammals when used for soybean seed treatment.” Environmentalists say approval of flupyradifurone would be irresponsible of PMRA because it would allow yet another chemical with a high potential hazard to bee health into the environment. Environmental groups, including Sierra Club Canada Foundation, David Suzuki Foundation, Pollination Canada, National Farmers Union, Friends of the Earth, and Canadian Association of Physicians for the Environment, have been vocal in expressing their concern about flupyradifurone: “Health Canada has admitted the use of neonicotinoid pesticides threatens bees and other pollinators and has promised a review, but meanwhile wants to open the door to its chemical cousin. Is the government taking the threat of systemic pesticides seriously?” said Lisa Gue, a researcher and analyst at David Suzuki Foundation. Karen […]
