Pathogens were isolated,purified and cultured with tissue separation method,and identified by morphological observation and molecular identification. The results showed that there were five main diseases that caused potato rotting in Huande County,Inner Mongolia during the storage period,including dry rot,late blight,early blight,ring rot and soft rot. Specifically,potato dry rot was the most serious disease,which was induced by four pathogens: Fusarium sambucinum,Fusarium Link,Fusarium acuminatum and Fusarium equiseti. Late blight caused by Phytophthora infestans and early blight caused by Alternaria solani could easily result in complex infection,which were mostly found in seriously rotted potato tubers. Moreover,these potatoes were always co-infected with fungal diseases at late stage of storage or even subject to complex infection with bacteriosis in serious cases. This study provided theoretical basis for the prevention of potato diseases during the storage period.展开更多
