水稻纹枯病的危害及其微生物防治概述

The Damage of Rice Sheath Blight and Its Microbial Control

水稻纹枯病是水稻的主要病害之一,化学杀菌剂虽能有效降低纹枯病的危害,但其易造成农药残留,破坏生态环境、病菌抗药性增强等诸多问题,而生物防治凭借其良好的环境兼容与可持续性独特优势,备受全球学者的青睐。通过简要概述水稻纹枯病菌的致病机理,生防微生物种类及其生防机理,以期为水稻纹枯病的防治研究提供有益参考。

Rice sheath blight（RSB） is one of the main rice diseases in the world. Although chemical fungicides can effectively reduce the harm of sheath blight, they can easily cause pesticide residues and environmental pollution, and also strengthen the drug resistance of bacteria. However, biological control is favored by global scholars for its unique advantages, such as good environmental compatibility and sustainability. In this paper, the pathogenic mechanism, bio-control microorganism species and biological control mechanism of rice sheath blight were briefly summarized in order to provide useful references for the study of rice sheath blight control.
