Abstract：In order to identify the pathogen causing tobacco black death disease in Henan prov-ince ,two strains were isolated from the disease infected plants in Xiangcheng and Wuyang by the methods of tissue separation and single spore isolation .The pathogens were identified based on their morphological characteristics and ITS sequences .Studies on the pathogens showed that colo-nies were initially white ,yellow or gray on PDA medium ,and they all produced acervuli ,bristles , conidiophores ,and conidia .Two strains were identified as the same species based on their rDNA-ITS ,which displayed 100% and 99% identities with DQ286158 .1 and HM231266 .1 ,respectively . It is confirmed that Colletotrichum capsici(Syd .) Butler & Bisby is the causal organism of tobac-co black death disease in Henan province .
