UGA Extension fruit pathologist says use lime sulfur on blueberries to manage Exobasidium disease

By Clint Thompson, University of Georgia

The key to managing Exobasidium leaf and fruit spot disease in blueberries, which makes the fruit unmarketable, is one application of lime sulfur approximately two weeks prior to bud break, according to Jonathan Oliver, University of Georgia Cooperative Extension fruit pathologist.

Exobasidium disease causes spots on the leaves and fruit, decreases the fruit’s size and, because of the fruit’s immaturity, gives it a bitter taste. The leaf spots eventually turn velvety and white and lead to early defoliation, and the spotted fruit is not fit for sale. Continue reading

UGA mycologists partner with the CDC to tackle fungicide resistance

by Merritt Melancon, University of Georgia

There are a limited number of compounds available to combat fungal infections in both plants and people. A team of University of Georgia researchers is helping to assess the risk posed by fungi developing widespread resistance to the stable of antifungal compounds used in the United States.

Michelle Momany, professor in the UGA Franklin College of Arts and Sciences Department of Plant Biology, and Marin Brewer, associate professor in the UGA College of Agricultural and Environmental Sciences Department of Plant Pathology, recently received a $197,798 contract from the Centers for Disease Control and Prevention (CDC) to study antifungal resistance in agricultural settings.

Spooky new fungal disease on southern golf courses unmasked
