| 摘 要： | 目的]掌握普洱市烤烟主要病虫害的发生流行规律和危害特点。方法]于2006～2008年对普洱市烟区主要病虫害进行了系统观测和大面积普查,并有针对性地提出了防治措施。结果]烟草花叶病(TMV和CMV)在烟苗移栽10 d后便开始发病危害烟株,6月中旬至7月上旬是危害高峰期;黑胫病在整个大田生育期均有危害,6月底达到危害高峰;青枯病属于区域性病害,5月上旬便开始危害并持续至7月底;赤星病从6月中旬开始零星发生,烟叶进入成熟采烤阶段后发病速度加快,8月中下旬进入发病稳定期;烟蚜发生危害主要集中在5月30日至7月10日,且有2个危害高峰;5月中下旬是烟青虫的始发期,7月上旬达到为害高峰。结论]普洱市烟草主要病虫害的发生流行、危害时期以及危害程度各不相同,防治应遵循"预防为主,综合防治"的植保方针,采取包括农业防治、生物防治、物理防治、化学防治等的综合防治措施。
