NOVEL MYCOVIRUS, ATTENUATED STRAIN OF PHYTOPATHOGENIC FUNGUS, PLANT DISEASE CONTROLLING AGENT, METHOD OF PRODUCING MYCOVIRUS, METHOD OF ATTENUATING PHYTOPATHOGENIC FUNGUS AND METHOD OF CONTROLLING PLANT DISEASE

摘要

The present invention provides a novel mycovirus that suppresses phytopathogenic fungi and a novel method for controlling plant diseases. A novel mycovirus that is present endogenously in a predetermined rice blast fungus, has four types of double-stranded RNAs of 2.8 to 3.6 kb, and suppresses a phytopathogenic fungus has been found. This virus suppresses phytopathogenic fungi such as rice blast fungus.
