苹果树枝干病害的生物防治研究

Study on Biological Management of Apple Tree Branch Disease

从苹果树体上分离得到颉颃菌株AT970 6。室内测定Valsamali等 3种枝干病害的病原抑制作用均为 10 0 %。田间采用AT970 6制剂对腐烂病和枝干轮纹病的防治效果分别为 99 5%和 86 0 %。

AT9706 stain,obtained from apple trees,had 100% inhibition to Valsa mali、Physalospora piricola and Botryosphaerla dothidea. The 100 times of antibiotic of AT9706 stain had 96.6%and 96 7%and 99 2% inhibition to Valsa mali et al .The control effect were 79 0% and 78.3% to Valsa mali and physalospora piricola by spraying in the field.
