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.

经过10余年对栗疫病发生特点和致病性的大量调查研究，结果表明栗疫菌在板栗分布区普遍存在，是弱寄生菌，在本地只寄生那些生长十分衰弱，即将死亡的板栗树干、苗木等，但栗疫菌的寄生不是这些部位死亡的主要和直接原因，而且它所寄生的部位局部死亡后对整株栗树的影响不大，因此，栗疫病在一般倩况下并非毁灭性病害。
