摘  要：
烟草野火病是赣州烟区烟草的主要病害之一。为探索防治该病的轮换药剂,进行了20%噻菌铜SC田间药效试验。田间药效试验结果表明:在烟草野火病发病前或发病初期,用20%噻菌铜SC 450倍液喷雾防治,每7 d 1次,连续2~3次,可有效控制该病的发生蔓延。第1次用药后7 d,20%噻菌铜SC 450倍液处理的防效为67.81%;第2次用药后7 d、14 d分别为68.98%、73.70%。同时在试验过程中,20%噻菌铜SC 450倍液处理,对烟株生长无不良影响。20%噻菌铜SC对烟草野火病具有较好的防治效果,可在赣州烟区烟叶生产上推广应用。

摘  要：
In order to explore the alternative chemicals against Pseudomonas syringae pv. tabaci,20% thiodiazole-copper SC were introduced to conduct field trials. The results showed that 20% thiodiazole-copper SC could effectively control the spread of tobacco wildfire disease before or during the initial stage by spraying at intervals of 7 d with the continuous use of more than two times. 7 d after the first spray,the efficacy of 20% thiodiazole-copper SC 450 treatment was 67.81%,7 d and 14 d after the second spray,the efficacy were 68.98% and 73.70%,respectively. Furthermore,it was also found that 20% thiodiazole-copper SC 450 had no adverse effects on the growth of tobacco during the field trials. So,20% thiodiazole-copper SC had relatively good control effects on tobacco wildfire disease,and thus it could be used in tobacco production.
