The rainy and humid season from July to September is the crucial period for elongation and jointing and yield performance of sugarcane,and also a peak occurrence and damage period of many important sugarcane diseases.In order to prevent large-area outbreak of sugarcane diseases and ensure safe growth in late stage,the occurrence dynamics of important sugarcane diseases in the rainy and humid season was analyzed and discussed from the aspects of three epidemic outbreak elements of plant diseases:host plant,pathogen and environmental condition.Moreover,the corresponding control ideas and technical countermeasures were put forward according to the epidemic characteristic of sugarcane diseases and the actual sugarcane production.
