摘　　要：在室内选用了6种生物药剂对尖孢镰孢菌进行了毒力测定。结果表明:在供试的药剂中,抑菌效果较好的药剂有低聚糖素、春雷霉素、克菌康,其中低聚糖素对尖孢镰孢菌的抑菌效果最好,EC50为18.20mg·L-1,春雷霉素次之,EC50为20.49mg·L-1。Toxicity measurements of 6 kinds of biological fungicides on Fusarium oxysporum were studied in laboratory. Results showed that oligosaccharide, kasugamycin, Zhongsheng-mycin inhibited the growth of Fusarium oxysporum obviously .Among them, oligosaccharide was the best inhibitor to Fusarium oxysporum and EC50 was 18.20 mg·L^-1. Kasugamycin had a better effect on inhibiting pathogen and its EC50 of kasugamycin was 20.49 mg·L^-1.
