Neonicotinoids

Neonic Seed Treatments in the (Science) News

Posted on October 27, 2020 in Environmental Impacts, Hot Science, Pesticides | 919 Views | Leave a response
It appears that scientists, and farmers too, are taking a closer look at the ubiquitous use of neonicotinoid seed treatments in US corn, soybean and other crops. Neonics are powerful insecticides used to coat the outside of a wide variety of seeds including grain and oilseed crops. The brightly-dyed layer of pesticide is designed to […]

Just a quick note to share a handy new resource put out by the University of Wisconsin’s Extension Office. “What’s on your seed?” is a one page guide to the many different types of seed treatments used on corn and soybean crops these days. Seed treatments are organized by active ingredient and treatment type (fungicide, […]

Early-Life Insecticide Exposure Compromises Brain Development in Bees

Posted on March 5, 2020 in Animals, Environmental Impacts, Hot Science, Pesticides | 829 Views | Leave a response
New science has, for the first time, replicated in a lab experiment the neural impacts on baby bees triggered when foraging adults are exposed to one type of insecticide. The widely used neonicotinoid (“neonic”) insecticide imidacloprid was the focus of the study done by a team at Imperial College London, whose key finding is summarized […]

Washington Oyster Farmers Let Go of Bid to Use Imidacloprid on Tidelands

Posted on October 23, 2019 in Environmental Impacts, In The News, Pesticides | 137 Views | Leave a response
The Seattle Times reported this week that oyster growers in southwestern Washington state have given up their years-long quest for permits to spray imidacloprid insecticides on their shellfish farms. This story has been brewing along the coastal mudflats of Gray’s Harbor and Willapa Bay, which are about three hours from Seattle.  Shellfish farmers, some of […]

Growing Evidence Tracks the Spread of Neonics Up and Through Branches on the Tree of Life

Posted on May 10, 2019 in Animals, Environmental Impacts, Hot Science, Pesticides | 720 Views | Leave a response
A Scientific American piece on neonicotinoid insecticides begins with a fascinating story about a wildlife rehab clinic in Montana. In the 1990s, a “bizarre trend” was noticed — an unusual number and diversity of birth defects in roadkill deer and other big game autopsied at the clinic. Scientists at the clinic pondered what could have […]

Prenatal and Early-Life Pesticide Exposures Associated with Increased Autism Risk and Severity

Posted on May 3, 2019 in Hot Science, Pesticides | 1,043 Views | Leave a response
A multidisciplinary research team including epidemiologists, bio-statisticians, and neurologists has identified a link between prenatal and infant pesticide exposure and increased risk of developing autism spectrum disorder (ASD) for residents of California’s Central Valley. The UCLA-based team started with a database of almost 3,000 people with a diagnosis of ASD born between 1998-2010 in eight […]

Neonic Insecticides and Metabolites ID’d in IA Tap Water, May Become More Toxic from Water Purification Process

Posted on February 21, 2019 in Environmental Impacts, Hot Science, Pesticides | 354 Views | Leave a response
Two years ago in 2017, scientists with the USGS and the University of Iowa first reported that neonicotinoid insecticides were “persistent” in drinking water samples collected at the University’s Iowa City campus during a seven week period after the corn planting season (May-July). The reason why was no mystery — at least 80% of the GMO […]

Research Team Documents Key Behavioral Changes in Bumblebees Exposed to Neonic Imidacloprid Using Robot-Guided Camera System

Posted on December 5, 2018 in Animals, Hot Science, Pesticides | 576 Views | Leave a response
We know that neonicotinoid insecticides are no-good for bees and other pollinators, even at very low levels of exposure. We know the major neonic — imidacloprid (Admire®) — is the single most acutely toxic pesticide to bees ever discovered, narrowly edging out the former #1 methyl parathion. But scientists are still trying to figure just […]

Dow Seeks Expansion for Neonic Replacement Sulfoxaflor, Despite EPA Classification of “Very Highly Toxic”

Posted on October 17, 2018 in Environmental Impacts, In The News, Pesticides | 900 Views | Leave a response
With neonicotinoid insecticides under fire for contributing to pollinator decline, Dow AgroSciences is pushing its sulfoxaflor insecticide as an alternative. As Environmental Health News reports, Dow applied to the EPA for an expansion of the registration of sulfoxaflor to allow use on “rice, avocados, residential ornamentals and at tree farms and greenhouses.” But, is this new […]

Politico Chimes In on Pesticide Industry’s “Losing Streak”

Posted on September 11, 2018 in In The News, Pesticides | 497 Views
Does the excerpt below from the September 10th issue of Politico’s Morning Agriculture e-newsletter sound familiar? It echoes sentiments on Hygeia in an “Endnote” to our August 20, 2018 post on the Lee Johnson verdict and award, which states — Endnote: The first half of August 2018 will go down in the history of pesticide use and regulation […]
