Seth McAllister and farmer Mark Daniel discuss crop production and agritourism. CAES News
A Shared Harvest
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.
The Peanut Innovation Lab has worked with Pyxus Agriculture, a private company in Malawi, to answer research questions that will help the company to build a formal peanut sector in the Southern Africa country. CAES News
Peanut Lab partners
The Feed the Future Innovation Lab for Peanut and Pyxus Agriculture Limited (Pyxus) has made it official, inking an agreement that formalizes a partnership that pairs university and private sector research efforts to improve outcomes for farmers in Malawi. In a Memorandum of Understanding between the Board of Regents of the University System of Georgia and Pyxus, the partners express their mutual interest in performing and disseminating research.
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
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.

Monarch Migration
With vigorous debate surrounding the health of the monarch butterfly, new research from the University of Georgia may have answered the biggest question plaguing butterfly researchers. Why are the wintering populations declining while breeding populations are stable? Published by the Proceedings of the National Academy of Sciences, the study suggests that monarchs are dying off during their fall migration south to Mexico.

Flocking to the classroom CAES News
Poultry Science Education
On a Monday morning in late June, just over two dozen middle- and high-school teachers trickled into a classroom at the University of Georgia Poultry Research Center and took their seats in groups of two and three. Hailing from public schools around the state, the teachers were preparing for Avian Academy, a highly popular three-day program for agriculture and STEM teachers hosted annually.
Planted three years ago during the pandemic, the University of Georgia’s Heritage Apple Orchard is starting to bear fruit and spark interest in the state’s agricultural history. Its 139 varieties hail from a time when Georgia was a major player in the country’s apple industry. (Photo by Michael Terrazas) CAES News
Heritage Apple Orchard
On a fine day at the University of Georgia Heritage Apple Orchard, you can see the fringing peaks of the Chattahoochee-Oconee National Forest rising around like a hedgerow, guarding against whatever forces might encroach. When Stephen Mihm looks over the tops of the 275-odd dwarf apple trees that constitute the orchard, he sees more than a pretty view of the Appalachian foothills. He sees clear into Georgia’s past.
Anna Blount CAES News
Love in Action
An 11-year-old girl changed everything for Anna Blount. Blount enrolled in the University of Georgia College of Agricultural and Environmental Sciences in 2001 with plans to go on to veterinary school. She loved animals and worked at a veterinary clinic while she earned her degree in biological science. But, as a college student, Blount also became a de facto parent.
