(, ); Novel Emergence of Black-Foot Causing Pathogen on Young Grapevines in China.

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 , based on both morphological and multi-locus phylogenetic analysis of ITS, and sequence data. For the first time in China, we report associated with symptomatic young grapevines. Koch's postulates were performed on 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.
