Abstract: In order to select more effective control medicaments against tobacco bacterial wilt of flue-cured tobacco, field experiments on tobacco bacterial wilt were conducted in Longyan, and the control effects were calculated. The results showed that the control effect of 72% streptomycin sulfate WP (North China Pharmaceutical Group Co., Ltd.) was the best, which was 36.15%; the control effects of 20% metalaxyl thiram WP and 72% streptomycin sulfate WP (Shijiazhuang Shuguang Pharmaceutical Factory) were the worst. Their control effects were 16.11% and 14.77%, respectively. Phytotoxicity of the several control medicaments did not appear against tobacco plants in different treatments. Therefore, 72% streptomycin sulfate WP (Chengdu Pratt & Whitney Biological Engineering Co., Ltd. or North China Pharmaceutical Group Co., Ltd.) is better against tobacco bacterial wilt in Longyan, Fujian Province. However, the mixed use of streptomycin sulfate WP and metalaxyl mancozeb WP should be avoided for better control effects.
