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. 
UGA mycologist Marin Brewer is using a recent USDA NIFA grant to continue her research of Aspergillus fumigatus, a fungus that is abundant in soil, compost and other organic debris. This fungus can cause serious lung infections in immunocompromised people. Michelle Momany, a professor in the UGA Franklin College of Arts and Sciences Department of Plant Biology, is collaborating with Brewer on this study. CAES News
Fungal Research
University of Georgia mycologist Marin Brewer has been awarded close to $500,000 from the United States Department of Agriculture National Institute of Food and Agriculture (NIFA) to search for ways to detect antifungal resistance in a naturally occurring fungus and identify the factors that contribute to its resistance in agricultural environments.
University of Georgia graduate student Zach Matteen conducted trials on 11 varieties of winter squash at UGA's Durham Horticulture Farm in Watkinsville, Georgia, on land used to grow organic crops. Matteen tested winter squash varieties 'Waltham' butternut, 'Zeppelin' delicata, 'Metro PMR' butternut, Seminole pumpkin, Choctaw sweet potato, 'Thai Kang Kob' tropical pumpkin, 'Thelma Sanders' sweet potato and a fifth-generation cross of 'Waltham' butternut and Seminole pumpkin. He found that the two sweet potato squashes and Seminole, tropical and tan cheese pumpkins held up best against squash pests and diseases. CAES News
Winter Squash
By determining the varieties best suited for the area, University of Georgia graduate student Zach Matteen is on a mission to convince more backyard gardeners and farmers to grow winter squash. He has found that Seminole, tropical and tan cheese pumpkins, as well as Choctaw and 'Thelma Sanders' sweet potato squashes, hold up best against squash pests and diseases.
University of Georgia researchers are studying the effectiveness of applying a Bacillus bacteria species to the stigmas of female flowers to slow the spread of bacterial fruit blotch from seed to seedling. CAES News
Battling Blotch
Georgia farmers struggle to control bacterial fruit blotch (BFB), but University of Georgia plant pathologists have discovered that naturally occurring bacteria can combat the disease.
Conks, fibrous but sometimes fleshy fruiting bodies of a wood-rotting fungus, grow on a tree CAES News
Tree Decay
Wood-rotting organisms can slowly nibble away at tree trunks and buttress roots. Many trees that topple look perfectly healthy before they fall. Afterward, it becomes clear that there were absolutely no structural roots remaining for support.

Female farmers
Women own 13.6 percent of America’s active farms and their farms produce almost $13 billion worth of goods each year. Just like male farmers, they need access to business and technical information to help make their farms successful. But while many pride themselves on not needing a “women’s only” class on how to work the land or run a business, many other women simply feel more comfortable learning around other female farmers.
When using pesticides, remember that the safe and legal use of pesticides requires that the entire label be followed exactly. Contact your local Extension agent if you're unsure about a product. CAES News
Pesticide Recertification Classes
Pesticides can be helpful in controlling insects and diseases, but there are chemicals that should be handled with care. To educate pesticide users, University of Georgia Extension has planned pesticide safety and handling classes in Albany, Savannah and Perry this February and March.
Cotton roots infected with root-knot nematodes swell in response to the infection. These knots serve as feeding sites where nematodes (microscopic worms) grow, produce more eggs and stunt the plant's growth. CAES News
Better, Healthier Cotton
Breeding cotton varieties with resistance to root-knot nematodes and better cotton fiber quality are at the forefront of Peng Chee’s research at the University of Georgia.
