摘　　要：[目的]筛选出抑制桑黑枯型疫病的理想药剂。[方法]以常规药剂100 mg/kg链霉素作对照,通过室内试验和大田小区防治试验测定不同浓度药剂的抑菌效果。[结果]室内试验结果表明,各种药剂对桑黑枯型疫病均有一定的抑制作用,但以盐酸环丙沙星最为经济有效,其次是盐酸恩诺沙星、诺氟沙星、链霉素和头孢塞呋。室外药剂防治效果与室内试验结果基本一致,其中链霉素和诺氟沙星的防治效果接近。使用药剂的经济有效浓度为100 mg/kg,最低有效浓度为12.5 mg/kg,药剂间复配未见有增效作用。[结论]盐酸环丙沙星是对桑黑枯型疫病有较好抑制作用的经济有效的抗菌素。[Objective] The objective of the study was to screen the ideal antibiotics for controlling mulberry black -blight. [Method] With a common antibiotic, 100 mg/kg Streptomycin, as CK, the inhibitory effects of several antibiotics with different concn, were determined in room experiment and field control test. [Result] The result of room experiment showed that all the tested antibiotics had somewhat inhibitory effects on the mulberry black -blight, in which, the antibiotic with most economic and effect was Ciprofloxaein hydrochloride, followed by Enrofloxaein hydrochloride, Nortlorxaein, Strepromycin and Ceftiofur hydrochloride. The result of field control test was similar to that of room experiment, in which, the control effect of Norflorxaein was close to that of Strepromyein. In practical application, the optimal eonen, and the lowest effective eonen, of the antibiotics were at 100 mg/kg and 12.5 mg/kg, resp. None synergism effects were found in any combinations between antibiotics. [Conclusion] Ciprofloxaein hydrochloride had better inhibitory effects on the mulberry black -blight, which was the economically effective antibiotic on this disease.
