摘要
病毒病在德阳晒烟上每隔１—２年大发生一次，造成重大经济损失。１９８９—１９９１年，采用ＥＬＩＳＡ等手段，鉴定了该地区晒烟病毒标样７２２个。结果表明，烟草普通花叶病毒（ＴＭＶ）、黄瓜花叶病毒（ＣＭＶ）、马铃薯病毒Ｙ（ＰＶＹ）是晒烟上的３种主要病毒。在不同年份或同一年份的不同时期，这３种病毒发生的比例各不相同。重病年以蚜传的ＣＭＶ、ＰＶＹ为主。烟草病毒病流行与否与２、３月的气温及雨日关系密切。调查了该地区的毒源植物，提出了以治蚜避蚜、提高烟株抗病力为中心的综合防治措施，取得了明显的防治效果。
Tobacco virus disease is widespread and catastrophic in Deyang every one or two years. It has not been clear about the virus types for many years. From 1989 -1991,722 Virus samples of sun-cured tobacco were identified with serology (ELISA), indicator hosts and electron microscopy. The results showed that TMV,CMV and PVY are dominant species in Deyang Sun - cured tobacco. Their proportion were 38. 7% (TMV), 46. 0% (CMV) and o2. 3% (PVY) respectively. Tomato spotted wilt virus (TSWV) has been found and identified also on Sun-cured tobacco.The statistical data from 1963 to 1991 showed that there exists a close relationship between disease seventy and climate, especially average temp. and rainy days in Feb.and March. The disease is more serious in high temp. and less rain. Many species of plants, including vegetables, weeds ……, are infected by TMV,,CMW or PVY in this district. A common weed of Solanaceae, Solanum xanthocarpum, are hosted by CMV.PVY. and aphid. It may be an important virus source host. An integrated control program, including killing and avoiding the aphid and earlier transplanting of tobacco, has been suggested, and proved to be effective on control of tobacco virus disease.
