从莱州市姜瘟病病株上分离出病原细菌 ,经形态性状观察 ,生理生化性状测定鉴定为Ralstoniasolanacearum。通过室内毒力测定选出毒力较强的药剂 ,进行田间药剂筛选试验表明 ,常规药剂防治难以控制其为害 ,而采用氯化苦熏蒸土壤和消菌灵浸种相结合的方案效果为佳。
The pathogenic bacteria were isolated from the diseased plants of Jiang Zhou of Laizhou City. Morphological characters and physiological and biochemical characters were identified as Ralstoniasola nacearum. Through the toxicity test in laboratory, the virulent drug was selected and the field drug screening test showed that it was difficult to control the damage by conventional drug control. The combination of chloropicrin fumigation soil and bactericide was better.
