Identifying Soybean Rust-resistant and Susceptible Populations of Kudzu to Increase Disease Monitoring Efficiency in Alabama

E. J. Sikora and M. A. Delaney

Research

Monitoring for soybean rust (SBR) in Alabama relies on biweekly scouting of kudzu in south and central Alabama. Some kudzu populations are naturally resistant or immune to infection from the pathogen, which can complicate early disease detection. The purpose of this was to study was to determine resistant or susceptible kudzu locations to increase monitoring efficiency and reduce costs associated with the scouting program. Focusing scouting on SBR-susceptible kudzu sites are expected to reduce costs of the monitoring program by approx. 25%.
