In April 2005, rust-infected Pueraria lobata (kudzu) was detected near Nelspruit, Mpumalanga, South Africa. At this location, kudzu plants occurred abundantly on road sides, edges of pine plantations, and in natural vegetation. Most vines were infected, with abaxial surfaces of older leaves often showing 100% severity. Following inoculation with rust spores collected from kudzu, soyabean line PI200492 (Rpp1) produced tan lesions typical of a susceptible reaction for Asian soyabean rust.
