New research from the University of Georgia has shown, for the first time, that compounds used to fight fungal diseases in plants are causing resistance to antifungal medications used to treat people. 

Eleven grants totaling $1.5 million were awarded in November 2021 to recipients of the third round of Presidential Interdisciplinary Seed Grants. Overall the awards went to faculty from 13 UGA departments, centers, programs, schools and colleges.

University of Georgia plant pathology researcher Melissa Mitchum will co-direct a $1.2 million award from the joint National Science Foundation and U.S. Department of Agriculture National Institute of Food and Agriculture (NSF-NIFA) Plant-Biotic Interactions Program to help combat a devastating soybean pathogen with colleagues at the University of Missouri.         

University of Georgia researchers have identified a new species of bacteria, which they have named Pseudomonas alliivorans — from “allium vorans,” which translates as onion devourer or eater.

Recently, a church trustee in Bartow County brought samples of “holey” mail to the local University of Georgia Cooperative Extension office for closer examination. Strangely, mail deposited in the church’s mailbox was showing up with holes chewed through the outer layer of the envelopes, but the mail inside was intact — a small miracle in itself.

As of Sept. 21, an invasive and dangerous pest, the Asian longhorned tick, has been confirmed in north Georgia. Experts are warning livestock producers and the public to be on the lookout, as the ticks can kill an animal by attaching to a host by the hundreds.

The use of cover crops has risen among both traditional and organic producers for a variety of reasons — to control erosion, choke out weeds, improve soil health and enhance water availability. Now research by University of Georgia scientists is examining which cover crops also may provide important habitat for predatory insects that could help control disease- and damage-causing pests in cotton.

Excessive rain signals another a bad year for leaf spot diseases on landscape trees and shrubs. The leaf spotting that affects pear trees, including both edible pears and ornamental Bradford types, is caused by a fungal disease known as Entomosporium leaf spot. This disease also affects related shrubs such as Indian hawthorn and red tip photinia.

An impressive team of University of Georgia researchers has received $765,000 from the U.S. Department of Agriculture’s National Institute of Food and Agriculture Crop Protection and Pest Management Program to support the continuation of integrated pest management (IPM) programming throughout the state over the next three years.
