Fungicides Driving Resistance
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.

Presidential Interdisciplinary Seed Grants
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.

NSF-NIFA Nematode Award
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.

New Bacteria Species
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.
“Slugs, by their very nature, must have moisture to survive and are known to eat damp paper on occasion,” said Agriculture and Natural Resources Agent Paul Pugliese. “The moral of the story: We now know why the postal delivery service is called 'snail mail.'” CAES News
Snail Mail
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.

Asian Longhorned Tick
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.
Cotton seedlings planted over a rye cover crop. After harvest, cotton fields are planted with a cover crop. Before cotton is planted the next season, the cover crop is killed and rolled , then the cotton seeds are planted using either a no-till or strip-till system. The resulting "mulch" provided by the cover crop residue provides insect habitat, moisture retention and some weed suppression. CAES News
Crop Ecology
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.
Entomosporium leaf spot on Photinia (Red Tip). Small reddish leaf spots appear initially. As spots age, center is grayish with a dark purple border. Leaf spots may coalesce causing severe leaf blight. Severely infected leaves drop prematurely. Over time severely infected plants die. Infection is favored by poor air circulation and prolonged periods of leaf wetness. CAES News
Leaf spot disease
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.
“To my knowledge, this is the all-time highest funding amount the UGA IPM program has received, which is incredible because this is a highly competitive national grant,” said Ash Sial, coordinator of UGA's integrated pest management program. CAES News
IPM Grant
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.
