Rust just found on kudzu in southeast GA; several new spore finds

“Numerous pustules and copious spores” found on kudzu leaf in Decatur County, GA

6:45 p.m. CDT—Soybean rust was confirmed this afternoon on kudzu growing in extreme southern Decatur County, Georgia, near the Florida border. “Numerous pustules and copious spores” were found on one leaf in a kudzu patch only two miles south of a Georgia sentinel plot.

The same patch was scouted last week without rust being sighted. Georgia officials say the new finding today: “further strengthens our belief that rust has spread to some degree in the state. Growers in the Coastal Plain are advised to begin a fungicide program as the crop enters reproductive growth and reassess the spread of disease before making additional applications.”
