The in Vitro Control by Hipovirulence of Chestnut

In this study it has been attempted to characterize some isolates of Cryphonectria parasitica both virulent and hypovirulent and to test the efficiency of the hypovirulent isolate as a biocontrol agent. After the identification of the two types of Cryphonectria parasitica isolates, they were grown in co-culture ant it was observed that the hypovirulent isolate grew faster than the virus-free isolates. The findings of this study are promising for the sustainability of Cryphonectria hypovirus as a biocontrol agent for chestnut blight
