3株木霉对杨树叶枯病病原菌的影响

Influence of 3 Trichoderma Strains on the Pathogenic Bacterium of Leaf Blight from Poplar Tree

采用PDA综合培养基对3株木霉和杨树叶枯病病原菌进行对峙培养,考察木霉对病原菌的抑制效果。结果表明,3株木霉对杨树叶枯病病原菌均具有拮抗作用,其中桔绿木霉2的抑菌效果最佳。

The confronting culture was performed on 3 Trichoderma strains and pathogenic bacterium of leaf blight from poplar tree using PDA synthetic medium and the inhibition effect of Trichoderma on pathogenic bacterium was investigated.The results showed that all of the 3 Trichoderma strains had antagonistic action on the pathogenic bacterium of leaf blight from poplar tree and the inhibition effect of Trichoderma citrinoviride 2 was best.
