目前国内鲜有关于番茄溃疡病菌对药物敏感程度的研究报道,本研究针对19株溃疡病菌对5种药剂的敏感性进行了测定,结果表明,19株菌全部对络氨铜和噻菌铜表现耐药,73.68%的菌株对氢氧化铜表现耐药,78.95%的菌株对0.1%溴硝醇溶液表现高度敏感,94.74%的菌株对链霉素表现高度敏感,说明目前使用链霉素防治番茄溃疡病的效果要远远好于铜制剂和溴硝醇;抗药菌株的出现,说明溃疡菌对药剂已经产生了抗性,对铜制剂的抗药性最强。
At present, there are few studies on the susceptibility of tomato canker to the drug sensitivity. In this study, the susceptibility of 19 strains of canker to 5 agents was tested. The results showed that all of the 19 strains showed good activity on copper ammonia and thiabendazole Resistant strains, 73.68% strains showed resistance to copper hydroxide, 78.95% strains were highly sensitive to 0.1% bronopol, 94.74% strains were highly sensitive to streptomycin, indicating that the current use of streptomycin control tomato The effect of ulcer disease is much better than that of copper preparation and bronopol. The appearance of drug-resistant strains indicates that the ulcer bacteria have already produced the resistance to the agent and the drug resistance to the copper agent is the strongest.
