| 摘 要： | 系统地调查云南烟草丛枝症病害的田间自然发病情况和介体发生情况，并实验测定烟草品种的抗病性，结果表明：烟草丛枝症病害在病区常年均有发生，最早发病时间在４月下旬，保山市１９９４，１９９５和１９９７年属一般年份，１９９３，１９９６和１９９８年属流行年份，导致病害流行的主要因素是苗期和移栽初期的两次蚜虫迁飞期高峰，以网罩隔离培育无毒烟苗、避开蚜虫迁飞高峰期移栽并同时施药是最有效的防治方法．目前生产上审定推广的品种全为高感品种，测定３１个烤烟和１４５个晒晾烟品种未发现抗病品种．

| Abstract: | Investigating systematically the circumstances of the infection of the field and vectors producing and detecting the disease resistance of sorts of tobacco,the result showed that the disease had often happened in these diseased places and begun in later April.The disease was serious in 1993,1996,1998,but was normal in 1994,1995,1997.The main factor of the disease happening was two summits of aphids migrating in young plants and early transplanting periods,so the effective ways were culturing health young plants isolated with net,transplanting not in the summits of aphids migrating and using insecticide during the time.No diseased resistant sort of tobacco had been found until now in production. |
