摘要
玉米纹枯病是一种主要由立枯丝核菌(Rhizoctonia solani)引起的重要真菌性病害,在世界范围内广泛发生,可导致玉米严重减产。通过介绍玉米纹枯病在我国的发生区域,症状特点与危害情况、发病规律与发生条件,并综述了玉米纹枯病菌的致病机制、抗玉米纹枯病的种质与基因资源挖掘进展及各种防控措施等,分析了目前防治玉米纹枯病存在的问题,旨在为玉米纹枯病的防控提供指导性意见。
Maize sheath blight,primarily caused by the fungus Rhizoctonia solani,is a significant fungal disease occurring widely worldwide and leading to severe yield reduction in corn.This paper provided an overview of the disease’s distribution in China,its symptomatic characteristics and damage effects,as well as its pathogenesis and prevailing conditions.Furthermore,it reviewed the recent advances in understanding the pathogenic mechanisms of R.solani,the exploration of germplasm and genetic resources resistant to maize sheath blight,and various control strategies.Current challenges in controlling this disease were also analyzed,aiming to offer a guidance for its prevention and management.
