摘要
In September 2014, severe stem blight, foot rot and storage tuber rot on sweet potato were observed in experimental fields in Sanmen County, Zhejiang Province, China. The causal agent was identified as Plenodomus destruens on the basis of morphological characteristics and molecular identification. In pathogenicity tests, P. destruens caused severe wilting, stem rot, and storage tubers rot symptoms similar to those observed in the field. This is the first report of P. destruens causing stem blight, foot rot and storage tuber rot on sweet potato in mainland China where sweet potato is a main crop.
