In June 2021, a leaf spot was found on Dracaena cambodiana on Yongxing island of Sansha City, Hainan Province, China. The disease mainly occurred at the tips or edges of older leaves. About 50% of leaves were showed necrotic symptoms. Similar fungal isolates were obtained from all sterilized sections incubated on PDA. The fungus was identified as Colletotrichum queenslandicum by morphological characteristics and multi-locus phylogenetic analyses with ITS region of rDNA, GADPH, CHS-1, ACT, GS and TUB-2 gene sequences. This is the first report of Colletotrichum queenslandicum causing leaf anthracnose on Dracaena cambodiana. [ABSTRACT FROM AUTHOR]
