A Shared Harvest 10/24/24 Emily Cabrera
On a sunny day with bright-blue skies, I arrive at Mark’s Melon Patch in Sasser, Georgia, and immediately spot the familiar white University of Georgia Cooperative Extension pickup truck, the Terrell County Extension logo prominently displayed on the door. Seth McAllister, the Agriculture and Natural Resources agent for Terrell County, greets me with a broad grin and a firm handshake. Terrell County alone has 60,000 acres of row crops, half in cotton. But what McAllister loves most about his role as an Extension agent is the diversity of his work.
Combining data collection and analysis with plant pathology, precision agriculture and robotics, the UGA team will build a photographic library of the foliar symptoms caused by onion diseases and other physiological disorders, feed them into the AI software, and use machine learning to identify the diseases based on pattern and color recognition from the images.

Vidalia AI 10/23/24 Jordan Powers
A multidisciplinary team of UGA researchers aims to enhance the competitiveness of Vidalia onion growers in Georgia by providing them with the ability to confidently detect onion diseases early, enabling them to make management decisions on their crop at a critical time. These abilities, researchers say, should result in increased yield and quality of marketable onions and an overall increase in efficiency and productivity.

Nematode Breakthrough 08/27/24 Julianne Johnston
Researchers have made a major discovery in the fight against soybean cyst nematode (SCN) by focusing on the genetics of the parasitic roundworms. Extensive genetic sequencing and mapping helped them identify a handful of likely genes behind the tricky pests’ ability to skirt soybean genetic resistance. Knowing how these SCN genes and soybean genes interact and evolve will help the industry identify the virulence of SCN populations so farmers can better use the genetic resistance currently available to fight the pest.
Cordyceps, the fungus behind The Last of Us, is real, and it actually does turn some species of ants into zombie-like creatures. The fungus penetrates the ant’s exoskeleton and begins to multiply. Eventually, the fungal cells take over the ant’s central nervous system. It causes the ant to fall from its primary habitat in the tree canopy to the forest floor. Then the fungus makes the zombified creature climb a tree to an ideal height of almost a foot off the ground. The ant bites onto the plant so forcefully that not even death can dislodge it. When the time is right, the fungus bursts from the ant’s body, scattering spores across the forest floor. And the cycle repeats. CAES News
Public Health Enemy 08/26/24 Leigh Hataway
As antimicrobial resistance grows, the world faces a deadly adversary few predicted: fungus. The battle against pathogenic fungi is raging, and UGA researchers are on the frontlines. “The fungus starts to direct the ant’s behavior, telling it where to go, what to do, like a puppeteer with a marionette. And it gets worse,” Dr. Neuman begins. “The fungus needs food to live, so it begins to devour its host from within, replacing the ant’s flesh with its own. But it doesn’t let its victim die. No, it keeps its puppet alive.”

UGA Plant Center 07/12/24 David Mitchell
The University of Georgia Plant Center is a collection of faculty and scientists from across multiple campuses who share common interests in plant science. From basic science in plant biology and genomics to highly applied projects in genetics and plant breeding, researchers run the gamut of plant-based research. More than 60 faculty are affiliated with the center, hailing from seven departments across four colleges and schools and three separate campuses in Athens, Tifton and Griffin.

Proper Watering 07/01/24 Timothy Daly
Now that summer is officially upon us, temperatures are up and areas of Georgia are experiencing abnormally dry conditions, you may be worried about how your yard is doing. Proper watering is key to helping your plants thrive. Excessive watering is one of the leading causes of issues in the home landscape. Yes, this issue can be a problem even during prolonged dry spells. A condition known as root rot develops, and marigolds, verbenas, hollies, boxwoods, azaleas and rhododendrons are some of the most sensitive.

Multidrug-resistant Fungi 06/26/24 Leigh Hataway
That pile of soil you bought at the home improvement store may contain more than just dirt, according to new research from the University of Georgia. A new UGA study found high levels of multidrug-resistant fungi in commercially available compost, soil and flower bulbs. Aspergillus fumigatus is a widespread fungus that thrives in soil. But it also poses a serious risk to human health if inhaled. People with compromised immune systems are particularly vulnerable to the opportunistic fungus.
Plant genetics research at the University of Georgia spans schools, departments, disciplines, and centers. From the College of Agricultural and Environmental Sciences (CAES) to Franklin College of Arts and Sciences, the Plant Center to the Institute of Plant Breeding, Genetics & Genomics and more, UGA faculty with genetics expertise are seeking plant-based solutions to societal challenges.

Plant Power 06/24/24 Stacia Pelletier
With record-breaking temperatures and extreme weather escalating, the threats posed by climate change are intensifying — but the plants of tomorrow could help us meet the massive challenges of our warming planet. Plant genetics research at the University of Georgia spans schools, departments, disciplines and centers. From the College of Agricultural and Environmental Sciences to Franklin College of Arts and Sciences, UGA faculty with genetics expertise are seeking plant-based solutions to societal challenges.

CURO Symposium 05/14/24 Olivia Randall
University of Georgia undergraduate students came together to showcase their individual research projects and achievements on April 8-9 at the Center for Undergraduate Research Opportunities (CURO) Symposium. For 25 years, the CURO Symposium has served as an opportunity to highlight the breadth and depth of undergraduate research across multiple disciplines. CURO enables undergraduates to engage in faculty-mentored research as early as their first year, regardless of discipline, major, or GPA.

Rural Engagement 05/13/24 Roy Parry
The interdisciplinary Rural Engagement Workshop for Academic Faculty, launched by Senior Vice President for Academic Affairs and Provost S. Jack Hu and Vice President for Public Service and Outreach Jennifer Frum, brings together academic faculty and public service faculty. This partnership expands the impact of UGA’s research and ties it to practical applications in rural communities across Georgia.
