[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 Ciprofloxacin hydrochloride,followed by Enrofloxacin hydrochloride,Norflorxacin,Strepromycin and Ceftiofur hydrochloride.The result of field control test was similar to that of room experiment,in which,the control effect of Norflorxacin was close to that of Strepromycin.In practical application,the optimal concn.and the lowest effective concn.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] Ciprofloxacin hydrochloride had better inhibitory effects on the mulberry black-blight,which was the economically effective antibiotic on this disease.
