摘　　要：通过对发病株率、病情指数、病死株率的调查,明确了康地蕾得细粒剂对烟草青枯病病菌的抑制率,并进行药效防治试验,观察康地蕾得细粒剂对烟草青枯病病菌的防治效果。结果表明:康地蕾得对烟细粒剂草青枯病病菌有一定的抑制作用,15.0kg/hm2、45.0kg/hm2、67.5kg/hm2、90.0kg/hm2的用药地块对青枯病的发病率有不同程度的降低,随着使用剂量的增加,防治效果有所提高,且在速效性、持续性及防治效果等方面优于对照药剂72%农用链霉素。The suppression ratios of Kangdileide FG against tobacco bacteria wilt were determined by the investigation of incidence,disease index and mortality of plants due to disease.The control effect of Kangdileide FG against tobacco bacteria wilt was observed by control experiment.The results showed that Kangdileide FG had definite inhibitory effect on tobacco bacteria wilt.From the control experiment,Kangdileide FG at 15.0kg/ hm2,45.0kg/hm2,67.5kg/hm2,90.0kg/hm2 all had certain control effect on Tobacco bacteria wilt.The control effect improved with the incr-ease of the using dosage and its effect such as the rapid availability, duration and control effect was better than the CK of 72% Agricultural Streptomycin.
