| Abstract: | In November 2019, the typical anthracnose fruits were collected from a papaya orchard in Danzhou City, Hainan Province. The isolate 23 was isolated by tissue isolation method and purified using single-spore isolation approach. According to morphological characteristics and phylogenetic analysis of ITS, GAPDH, TUB, and ACT gene sequences, the pathogen was identified as Colletotrichum okinawense. This is the first report of C. okinawense caused anthracnose on papaya in China mainland. |
