Abstract: A new disease-Dongzao jujube black spot in Hebei and Shandong provinces was reported. The black spot of Dongzao jujube has been studied in the laboratory and in fields during 2004-2005. 653 isolates from 219 infected Dongzao jujube samples from eighteen times of sample collection were selected, purified and reinoculated. The pathogens were inoculated on fruits through wounds and on surface directly. According to Koch's Rule and cultural and morphological characters, two fungal pathogens were identified as Alternaria alternata (Fr.) Keissler and Phoma destructive Plower.

Key words: Dongzao jujube, Black spot, Identification of pathogens
