Abstract |
Leaf blight of kudzu was found in Jeonbuk province in 2002. Water-soaked lesion appeared on leaves, and young stems and gray green blight sypmtom expanded from margin to main vine of leaves. As the disease became severe, blighted leaves and shoots turned dark brown and then collapsed. The causal pathgen showed initially white aerial mycelium and turned brown to gray. Mycelia were branched at 90˚ angles and multinucleate in one cell. It formed sclerotia on PDA. Slerotia were irregular, globose and 0.5~3.0 mm in diameter. The causal fungus of leaf blight was identified as Rhizoctonia solani Kuhn based on the cultural and morphological characteristics. This is the first report on leaf blight of kudzu caused by R. solani in Korea. |
