Species Identification and Control Countermeasures of Tobacco Virus Disease in Hezhou City

从贺州市主要产烟区采集疑似病毒病症状的烟叶样品71份,并对症状进行了拍照和描述记载,采用ELISA法对样品进行了检测。检测出TMV、CMV、To MV、Ts WV 4种病毒病,检出率分别为51.87%、46.92%、19.35%、74.79%,复合侵染率为71.83%,以TMV和To MV复合侵染为主,病毒阳性检出率和采集烟叶样品发病特征基本吻合。同时对贺州市烟草病毒病发生原因进行分析,提出了有针对性的防治措施。

71 tobacco samples were collected from major tobacco producing areas of Hezhou City. The symptoms were recorded and described. Detected a total of tobacco mosaic virus （TMV）, cucumber mosaic virus （CMV）, tomato mosaic virus （ToMV）, tomato spotted wilt virus （TsWV）, their detection rates were 51.87% ,46.92%, 19.35%, 74.79% respectively;the detection sample to complex infection ,positive ratio up to 71.83%, and TMV and ToMV co infection was the main infection type.Positive delection rate and disease characleristics reached the match.
