Study Finds Chemical Industry’s “Bee-Safe” Claim for Its Pesticides To Be False

(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 […]

Strawberries Lose Their Sweetness, Aroma, and Taste after Being Sprayed with Chemical Fungicides, Study Finds

(Beyond Pesticides, March 1, 2023) Fungicides sprayed on chemically farmed strawberries reduce their flavor quality, according to research published in the Journal of Agricultural and Food Chemistry this week. This explanation is a major insight for frustrated consumers who may remember when the strawberries sold at retail contained deeper, more complex flavors. As the agrichemical industry claims that dangerous pesticides are needed to grow food to feed the world, it is evident these practices health and environmental hazards, but also affect the quality of the food grown. As savvy shoppers and gardeners already know, buying and growing organic addresses this range of issues, improving flavor while protecting wildlife and public health. Scientists developed their study to better understand the mechanisms leading to flavor deterioration by growing strawberry plants in a greenhouse with chemical-intensive practices, including the use of synthetic fertilizers. One group was treated with the fungicide boscalid, another with the fungicide difenconazole, and a control group received no spray. Fruits were sprayed beginning at the green, small fruit stage, a total of two times, and collections from each group were taken at the white, turning, and red fruit stage (zero, three, and seven days after the second pesticide application).
