本文对赣州信丰烟区旱地烟草青枯病的发生规律及不同药剂在不同时期使用的防治效果进行了研究。试验结果表明，在信丰烟区旱地烟田，烟草青枯病的始发期在4月中下旬，盛发期在5月下旬至6月初；两种药剂在不同时期施用的试验结果表明，两种药剂对抑制青枯病的发生均具有一定作用，其中解淀粉芽孢杆菌(烟顺)的防治效果较好。两种药剂都是在最早施用时期防治青枯病的效果最好。
The occurrence regularity of tobacco bacterial wilt on dry land in Xinfeng County and the control effects of different chemicals in different periods were studied. The results showed that the initial period of dry land tobacco bacterial wilt in Xinfeng tobacco area was mid-to-late April, and the peak period was from late May to early June. The control efficiency tests of the two agents at different application periods show that both agents have a certain effect on inhibiting the occurrence of bacterial wilt disease, and the control effect of Bacillus amyloliquefaciens (Yanshun) is better. Both medicaments have the best effect on controlling bacterial wilt in the earliest application period wilt.
