摘要： The black-foot disease of grapevine is one of the most destructive diseases in viticulture and it is caused by a complex of soil-borne fungi. This study aimed to identify the species associated with black-foot disease in young grapevines in vineyards of China. Fungal isolates were identified as Campylocarpon fasciculare, based on both morphological and multi-locus phylogenetic analysis of ITS, tef1-alpha and ss-tubulin sequence data. For the first time in China, we report Campylocarpon fasciculare associated with symptomatic young grapevines. Koch's postulates were performed on Vitis vinifera cv. Summer Black (SB) in a greenhouse and to confirm the pathogenicity on grapevines. This work improves the knowledge of black-foot disease in Chinese vineyards and will be helpful to growers in their decisions regarding vinicultural practices, planting and disease management.
