Feb 18, · Goals / Objectives Transmissible hypovirulence of the chestnut blight fungus, cryphonectria parasitica, is a natural biological control for this disease. Hypovirulence is caused by a double-stranded (ds) RNA virus which infects the fungus, the result of which is a reduction of sporulation and virulence expression toward chestnut by the fungus.
