New Rust Disease of Korean Willow (Salix koreensis) Caused byMelampsora yezoensis, Unrecorded Pathogen in Korea.
During the growing season of 2015, leaf specimens with yellow rust spots were collected fromSalix koreensisAndersson, known as Korean willow, in riverine areas in Cheonan, Korea. The fungus onS. koreensiswas identified as the rust species,Melampsora yezoensis, based on the morphology of urediniospores observed by light and scanning electron microscopy, and the molecular properties of the internal transcribed spacer rDNA region. Pathogenicity tests confirmed that the urediniospores are the causal agent of the rust symptoms on the leaves and young stems ofS. koreensis. Here, we report a new rust disease ofS. koreensiscaused by the rust fungus,M. yezoensis, a previously unrecorded rust pathogen in Korea.
