摘　　要：采用生长速率法进行了康地蕾得(多粘类芽孢杆菌)对黄瓜枯萎病的室内毒力测定,结果表明:康地蕾得对黄瓜枯萎病菌毒力很强,EC50、EC70及EC90值分别为920.21、1387.39、2510.15mg/L。田间药效试验结果表明:康地蕾得FG对黄瓜枯萎病均具有良好防效,使用剂量在30～45kg/hm2范围内对黄瓜枯萎病的防效为57.08%～73.48%,在速效性、持效性及防治效果等方面优于对照药剂3%多抗霉素WP。The toxicity of Kangdeleide to the Fusarium omysporum（Schl） f.sp. cucumerinum Owen was tested in laboratory. The results show that the toxicity of Kangdeleide is the stronger, with EC50, EC70 and EC90 values of 920.21, 1387.39, 2510.15 mg/L. The field efficiency trials indicated that Kangdeleide FG has relatively high effects on cucumber Fusarium Wilt, the control activity was 57.08% to 73.48% in field at the rate of 30 to 45 kg/ha, was better than Polyoxin 3% WP in effective and duration.
