Ten years wide investigation and research on the characteristics and pathogenicity of cryphonectria parasitica showed that, Cryphonectria parasitica existed widely in the distributing areas of Castanea mollissima, and that it belonged to weak parasite, only lived on the weak and dying branchs, sprouts, and soon. Cryphonectria parasitica was not main and direct death cause of Castanea mollissima, and the dead parts had no great influence on the growth of whole tree.
