Identification of Pathogen of Potato Rot Disease Inner Ventilation Bank of Huade County, Mongolia during Storage Period
摘要
Abstract
[Objective] The aim was to clear main pathogen of potato rot disease inner ventilation bank of Huade County, Mongolia during storage period.[Method] We sampled rotten potato during the storage period from October, 2015 to April, 2016 inner ventilation bank of Huade County, Wulanchabu City, Mongolia, used organizational separation method to separate and culture pathogens, and defined through the means of morphology and molecular identification.[Result] There were several diseases to cause potato rot disease during the storage period in Huade County, such as dry rot disease(Fusarium spp.), late blight disease(Phytophthora infestans), early blight disease(Althernaria solani),ring rot disease(Clavibacter michiganense subsp.sepedonicus) and rot disease(Erwnia spp.), among them the dry rot disease was the main disease.There were 4 kinds of pathogens cause dry rot disease of potato through the identification, such as Fusarium sambucinum,Fusarium Link,Fusarium acuminatum and Fusarium equiseti.The late blight disease caused by Phytophthora infestans and early blight disease caused by part Alternaria solani were often happened in much serious rot potatoes which occurred mixed infection, and these potatoes were always infected by variety of fungi in the late period of storage, the severe rotting potatoes were occurred complex infection by bacterium.[Conclusion] The results provide theoretical basis for disease control of potato during storage period.关键词
