摘要
以春雷霉素为对照药剂，采用生长速率法开展吩胺霉素对黄瓜枯萎病菌的室内毒力测定试验。结果表明：吩胺霉素对黄瓜枯萎病菌毒力很强，EGo和Ec如分别为1．1999、11．6096mg/L。田间药效试验表明：吩胺霉素防治黄瓜枯萎病效果较好，在150-250mg／L浓度范围内对该病害的防效为66．27-76．59％，且速效性和持效性等方面均优于对照药剂春雷霉素。
The toxicity of fenanmycin against the Fusarium oxyspoum f. sp. cucumerinum Owen was tested in laboratory with kaxugamycin as the contrast fungicide （CK）. The results showed that the toxicity of fenanmycin had strong effects and the ECs0and EC9o were 1.199 9 mg/L and 11.609 6 mg/L, respectly. The field efficiency trials indicated that fenanmycin had relatively high effects on cucumber Fusarium wilt and the control activity was from 66.27% to 76.59% in fields at the concentration range from 150 to 250 rng/L, which showed fenanmycin was better than kaxugamycin in control efficacy and duration.
