Abstract: Mycovirus is a kind of virus that proliferates within fungi and widely exists in various fungi.In agricultural production,70%-80% of plant diseases are caused by fungal infection.The infection of mycovirus is capable of attenuating the pathogenicity of host fungi and convert them to endophytic fungi,which can promote plant growth and disease resistance.Therefore,mycoviruses can be acted as biological control resources.In this paper,the mechanisms of mycoviruses attenuating hosts'pathogenicity and their application in the management of plant diseases were reviewed,and the prospects and difficulties of mycoviruses in biological control were put forward as well.This review will provide reference for the biological control of plant fungal diseases.

Key words: mycovirus, fungal disease, biological control, pathogenicity
