本文将植物源药剂作为增效剂，与噻菌铜等化学制剂联合施用，考察该方法对烤烟大田青枯病的发生情况、烟叶产质量的综合影响。结果表明，将植物源药剂与噻菌铜联合施用，单一防治防治青枯病时，相对防效为83.1%，产量比对照增加12.72%，产值增加16.93%。其防治方法为：将植物源药剂600 kg/hm2、奇农素600 g/hm2和噻菌铜3种药剂混配，于青枯病高发期前进行3-4次灌根。

Abstract: This article took the botanical medicine as synergistic agent jointed with chemical medicine to search the control effect of bacterial wilt, the yield and output value in those two fields. It was shown that, by the jointing measurement of botanical medicine and thiediazole copper, the relative control efficiency could be 83.1%, yield was 12.72% higher than CK, output value was 16.93% higher than CK. To achieve this effect, we should apply 600 g/hm2 Qinongsu, 600 kg/hm2 botanical exacts with thiediazole copper to roots 3-4 times before the disease occurs.
