|
The occurrence of gray mold on has recently been reported in Pohang, Gyeongbuk province, Korea. The initial symptom was the appearance of small brown spots on the leaves, and these lesions became later covered with a gray fungus as the disease progressed. A fungus was isolated from symptomatic leaves and incubated. Through morphological and phylogenetic analyses, the causal agent of the disease was identified to be . The fungal isolate was then used to inoculate on the leaves of healthy plants to determine its pathogenicity as the causal agent of gray mold as per Koch’s postulates. The inoculated leaves showed the same symptoms as the originally infected plant, and the fungal pathogen re-isolated from the lesions showed the same morphological characteristics as the original pathogen. This is the first report on the occurrence of gray mold on caused by in Korea.
