Study on Pathogenicities of pathogenic Fungi of Corn Stalk Rot in Corn Seedling Stage
Jin Qiming Lu Zhongzi Pan Shunfa Jiang Jingchun (Institute of Plant Protection,Jilin Academy of Agricultural Sciences,Gong Zhuling 136100)
The Pathogenicities of pathogenic fungi (Fusarium graminearum,Pythium graminicola and Pythium catenulatum)were tested during the seedling stage of the corn. The result showed that all these three species of fungi could induce the corn stalk rot in seedling stage. The pathogenicity of pythium spp was stronger than Fusarium gramin-earum. Both these infection courts were different. Pythium spp infected secondary root and fibrous root. However, Fusarium graminearum infected embryo root. The mixed pathogenicity of the three strains was also trialed.
