摘　　要：随着新疆生产建设兵团农业产业结构的调整，红枣种植推广面积不断扩大，枣园也随之出现了新病害，红枣黑点病就是其中之一。大田调查发现。该病目前仅感染骏枣，发病轻的果园病果率为1％～5％，重者病果率可达30％以上。自2010年在南疆和田地区发现该病以来，病害在枣园有进一步蔓延的趋势。Black spot disease was found on fruits of Jun jujube in Hetian area, Xinjiang, in June, 2010. The typical spots on fruits were round or suborbicular, concave slightly, dark brown and the diameter was about 4 mm. The colony grew fast with irregular edge on PSA medium, while relatively slow with smooth edge on PDA medium. The colonies were white at the early stage, slightly pink finally and flocculent on the both culture medi- um. The conidia arranged chain shape and the spore chain was basipetal. The rDNA ITS sequence, cyt b gene se- quence and EF-la gene sequence were amplified and analyzed. The result showed that the homology was above 99% between the isolate and Fusarium verticiUioides strains based on the three DNA sequences. By morphology combining with molecular biology techniques, the pathogen of Jun jujube black spot disease was identified as F. verticillioides. It is the first report on jujube disease caused by F. verticillioides in the world.
