Fungal Resistance to Antimicrobial Pesticides Leads to Deadly Infection

November 23, 2021 | The U.S. Environmental Protection Agency (EPA) announced in mid-October 2021 a revision of its guidance on the evaluation of antimicrobial pesticides used against Candida auris (C. auris). This pathogen is a type of fungus (a yeast) that can cause serious infection and can spread readily among patients and staff in hospitals […]

Secret Inert Ingredient in “Bee Safe” Pesticide Found to Kill Bumblebees

November 11, 2021 | Evidence is building that so-called “inert” ingredients in pesticide formulations are harming pollinators and undermining regulatory determinations that designate products as “bee safe.” According to a study published in Scientific Reports, the fungicide Amistar causes lethal and sublethal effects that can be primarily attributed not to its active ingredient azoxystrobin, but […]

Aquatic Wildlife Populations Take a Nosedive after Neonicotinoid Exposure

November 10, 2021 | The diversity and abundance of freshwater aquatic insects plunges when commonly used neonicotinoid (neonic) insecticides leach into waterways, finds research published in the Proceedings of the National Academy of Sciences. While this is the latest study exploring the effects of neonicotinoids in the field at real-world exposure levels, it is far […]

Weeds Are Now Developing Resistance to Herbicides They’ve Never Been Exposed To

October 13, 2021 | Pesticide use in conventional chemical-intensive farming is so pervasive that weeds are developing resistance to herbicides they have never encountered before. According to research published in Plant and Cell Physiology and New Phytologist, the notoriously difficult-to-control weed waterhemp (Amaranthus tuberculatus) is outpacing commercial crops in its ability to detoxify after herbicide […]

Monoculture Agriculture Leads to Poor Soil Health

October 5, 2021 | Soil and soil quality are declining rapidly in the U.S. and around the world, with recent data indicating that the U.S. Corn Belt has lost 35% of its topsoil. “Understanding the management practices that lead to healthier soils will allow farmers to grow the same crops while reducing costly chemical inputs […]

Conventional Agriculture Decreases Diversity of Gut Bacteria in Foraging Bats

September 29, 2021 | Bats foraging in chemical-intensive banana plantations have much less gut diversity than bats foraging in organic banana fields and natural forestland, finds research published in Frontiers in Ecology and Evolution. Although there is increasing recognition that a diet of conventional, chemically grown food leads to adverse disruptions of the gut microbiome […]

Common Mosquito Pesticide Exacerbates Health Issues Associated with Zika Virus

September 28, 2021 | A widely used mosquito pesticide may exacerbate the effect of the Zika virus on fetal brain development, according to research published by an international team of scientists in Environmental Pollution. Pyriproxyfen, an insect growth regulator often used as a mosquito larvicide, is registered for use in hundreds of commonly used pesticide […]

Studies Show How Pesticides Harm Organisms that Form the Foundation of Freshwater Ecosystems

September 15, 2021 | Toxic pesticide use, and glyphosate in particular, degrades the health of freshwater ecosystems by harming species that form the basis of aquatic food chains, according to research published by scientists at McGill University. In a series of studies, scientists investigated how freshwater bacteria and zooplankton are affected by varying levels of […]

Endangered Species Likely to Be Hard Hit by Neonicotinoid Insecticides, EPA Finds

September 8, 2021 | (September 8, 2021) The U.S. Environmental Protection Agency (EPA) in August 2021 released a long-overdue biological evaluation of the three most commonly used neonicotinoid (neonic) insecticides, finding that the chemicals are likely to adversely affect the lion’s share of endangered species and their habitat. While the public may be most familiar […]

Of Multiple Stressors, Pesticides Are the Most Harmful to Bees by Acting Synergistically to Increase Mortality

August 11, 2021 |Multiple stressors, including pesticides, parasites, and poor nutrition, act synergistically to increase the risk of bee mortality, according to a meta-analysis published in Nature. The findings are yet another indictment of the U.S. pesticide regulatory system’s ability to protect pollinators, as the authors note that their results, “. . . demonstrate that […]
