摘　　要：调查研究发现,广西烟草病毒病有烟草花叶病毒病(TMV)、黄瓜花叶病毒病(CMV)、马铃薯Y病毒病(PVY)、烟草蚀纹病毒病(TEV)、烟草环斑病毒病(TRSV)和由番茄黄化曲叶病毒(TYLCV)引起的曲叶病毒病等6种,其中TMV分布最广、危害最大;烟草病毒病的发生与主栽品种抗病性、虫媒、气候、种植区域调整及农事操作等因素有关。2005～2007年连续3年在广西靖西县开展烟草病毒病综合防治试验示范,综合防治效果分别为90.38%、89.51%和82.35%,示范区烟草病毒病发病率和病情指数明显降低,上等烟比率、单产、产值等均比对照区高,示范区烟草病毒病综合防治取得了显著效果。The investigation showed that there were 6 kinds of virus diseases of tobacco in Guangxi, which were tobacco mosaic virus （TMV）disease, tobacco cucumber mosaic virus （CMV） disease, tobacco potato y virus （PVY） disease, tobacco etch virus （TEV）disease , tobacco ringspot virus （TRSV）disease and tobacco leaf curl disease caused by tomato yellow leaf curl virus （TYLCV）. Among them TMV disease occurred popularly and caused the greatest damage. The incidence of tobacco virus disease had close relationship with tobacco species, insect vectors, climate, planting region and field operation. The integrated control experiments on tobacco virus disease were conducted during the years of 2005-2007 in Jingxi County of Guangxi. The control effects were 90.38%, 89.51% and 82.35% respectively in the three years, and the yield and rate of high grade tobacco leaf were higher in tested area than that of control area.
