Chinese Jujube (Ziziphus jujuba) is a common fruit tree used in landscaping, medicine and timber. However, Jujube trees are threatened by various pathogens in the process of planting and cultivation. In this study, destructive canker diseases of Z. jujuba were investigated in Beijing, China. Based on morphological comparison and DNA sequence analysis, the causal organisms of these diseases were identified as Dothiorella acericola and Nothophoma spiraeae. This is the first report of D. acericola and  N. spiraeae on Z. jujuba. This study improves our understanding of fungal species causing canker or dieback disease on this economically important tree and provides insights on selecting the effective disease management strategies for Z. jujuba in China.
