Research on Variation of Sugarcane Red Rot ( Colletotrichum falcatum Went) and Sugarcane Disease Resistance

摘要

Sugarcane red rot caused by Colletotrichum falcatum Went is one of the important fungal diseases causing significant losses to sugarcane production,commonly known as "cancer" of sugarcane.It has risen from a minor disease to a major disease,resulting in the death of sugarcane in Lincang,Menglian and Shiping sugarcane areas in Yunnan Province.Due to the frequent variation of this pathogen,it is difficult to control,the pesticide control effect is not ideal at present,and there is still no effective and radical cure measures.The research on the variation of C.falcatum and sugarcane disease resistance is the only way to achieve the sustainable control of sugarcane disease.This paper mainly reviewed the genetic variation on the morphological,pathogenic and molecular variation of C.falcatum,and rapid molecular detection methods,and sugarcane disease resistance research in combination with the latest research at home and abroad.An outlook for further research on sugarcane red rot in the future was also given,to provide a theoretical basis for the research and control of sugarcane red rot in China.
