Abstract: 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.
