Abstract:

Sugarcane smut seriously endangers sugarcane production,resulting in reduced sugarcane yield and sucrose loss. It is dispered through wind and soil,its teliospores could survive for more than half a year in hot and dry conditions. Rhizosphere microecology is a micro-ecosystem in which roots are closely related to soil. The environmental factors of the system,such as soil microorganisms,root exudates and soil physicochemical properties,have an extremely important impact on the growth and development of plant. Similarly,the development and prevention and control of plant diseases is also closely related. The research on characteristics of sugarcane rhizosphere micro-ecosystem and the internal relationship between it and sugarcane smut is conducive to the early prevention of sugarcane smut and the exploration of biocontrol resources. This paper summarizes the previous research progress from the following these aspects:the occurrence and harm of sugarcane smut,the relationship between plant rhizosphere microecology and diseases,sugarcane rhizosphere microecology and smut control. It aims to provide reference for the research of sugarcane rhizosphere microecology,the excavation of excellent biological control resources and the efficient control of sugarcane smut.

Key words: sugarcane, smut, rhizosphere microecology, control measures
