摘　　要：采用菌丝生长速率法在室内测定了鲍曼菌素活性粗浸膏对梨黑斑病、轮纹病、炭疽病及草莓立枯病的毒力,并采用接种法测试了它对梨果实轮纹病的防治效果。结果表明:鲍曼菌素活性粗浸膏抑制梨黑斑病、轮纹病、炭疽病病菌菌丝生长的EC50值分别为0.022、0.027和0.079mg/L。用鲍曼菌素活性粗浸膏333～666mg/L对感染梨轮纹病的果实接种后的防治效果为84%～94%。The fungitoxicity of Acinetobacter baumannii crude active product against pear black spot,pear ring rot disease,pear anthracnose and strawberry sheath blight was assessed by mycelial growth rate method,and its biocontrol effect on pear ring rot disease was tested by inoculation method.The results showed that the EC50 values of A.baumannii crude active product to the mycelia growth of pear black spot,pear ring rot disease and pear anthracnose were 0.022,0.027 and 0.079 mg/L respectively.The control effect of A.baumannii crude active product(333-666 mg/L) against pear ring rot disease was 84%-94%.
