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 […]

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 […]

Deer Ticks Developing Resistance to Popular Tick Control Chemical: Implications for Lyme Disease

July 22, 2021 |A study published in the Journal of Medical Entomology finds black-legged ticks (Ixodes scapulari) in New York are developing potential resistance to widely used tick-control pyrethroid insecticide, permethrin for the transmission of Lyme disease. The study suggests continuous use of area- wide, 4-poster devices (devices that attract deer and then apply pesticide […]

Disease Carrying Mosquitoes Developing Resistance to Widely Used Mosquito Control Pesticides

July 1, 2021 | Yellow fever mosquitoes (Aedes aegypti) are evolving resistance to the pyrethroid insecticide permethrin, according to a study published by Colorado State University researchers in PLOS Genetics, highlighting the need to adopt ecologically-based mosquito management. Widespread, intensive use of the pesticide in mosquito control has allowed genetic mutations to persist among these […]

Threat to Ocean Health: Pesticide Resistant Fish Lice Plague the North Atlantic Ocean

June 3, 2021 | (A report published in Royal Society Open Science finds pesticide-resistant parasitic lice (Lepeophtheirus salmonis) are endangering wild and farmed fish populations in the North Atlantic. Extensive use of pesticides to rid the parasite has led to widespread resistance to multiple pesticides, prompting increasing infection rates among North Atlantic salmon populations. Some […]

Glyphosate and Other Weed Killers Create Antibiotic Resistant Bacteria in Agricultural Soils

February 24, 2021 | Soil sprayed with weed killers glyphosate, glufosinate, or dicamba are likely to contain higher amounts of antibiotic resistant bacteria, according to research published in Molecular Biology and Evolution. Each year in the U.S., at least two million people develop an antibiotic resistant infection and over 23,000 die. Authors of the study […]
