The powdery mildew of Statice (Limonium shinuatum) extensively occurred in the experimental farm of Changwon Floricultural Experiment Station, Kyongsangnam-do Agricultural Research and Extension Services in 2000. Both sides of the leaves, petioles and stems were covered with the white fungal spores and mycelia, and then the leaves, petioles and stems became dark-colored, eventually died. The conidia and conidiophores formed on the lesion were observed. Conidia were cylindric to ellipsoid, 25.3∼49.4 × 12.3∼17.2㎛ in size and borne singly on conidiophore. Fibrosin bodies were not observed. Conidiophores were straight with 2-4 cylindric cells, and 65.7∼124.8㎛ in size. Appressorium was lobed type. Cleistothecia were not formed. This is the first report on powdery mildew of Statice (Limonium shinuatum) caused by Oidium sp. in Korea.
