Abstract: In order to compare effects of applying different kinds of bio-organic fertilizer with antagonist on tobacco bacterial wilt and make proper suggestion on how to produce tobacco with the principle of ‘unpolluted, high quality and safety’, field experiment was carried out to find out the effects of different kinds of bio-organic fertilizer on tobacco growth, yield, configuration and bacterial wilt in Xuan’en County, Hubei Province. Results showed that applying the 7 different kinds of bio-organic fertilizer with antagonist could promote tobacco growth and improve the ratio of top rank by 12.80-33.59 percent point, but decrease yield by 2.91% to 38.18%. The bacterial wilt was suppressed in each treatment during resetting and fast-growing stage of tobacco, and the control efficacy in treatment 4 [3750 kg bio-organic fertilizer per hm2 (20% rapeseed meal & 20% carbonized rice husks
