为了探究烟叶采后白粉病菌在烘烤过程中的侵染情况，以烟草品种南江3号为材料，研究了不同寄主植物白粉病菌对烟叶的侵染情况。结果表明：不同寄主植物的白粉病菌成活率和侵染率以烟草白粉病菌最高，分别为66．7％～88．9％和50．0％～88．9％，烟田周边的植物中，羊蹄、水蛇麻、风轮菜、地雷花和葵花上的白粉病菌均能侵染烟叶导致烟叶白粉病，侵染率为5．6％～50．0％，以地雷花的侵染率最高，达50％；在烟叶烘烤过程中，烟草、地雷花、风轮菜、葵花和水蛇麻上的白粉病菌只能在散叶堆放阶段和鲜烟装炕阶段侵染烟叶，侵染率为5．6％～88．9％，在烟叶烘烤的后续阶段不能感染。

Nanjiang 3,a tobacco variety,was used to study the infection status of Erysiphe graminis from different hosts to tobacco during the tobacco curing process.The survival rate and infection rate of Erysiphe cichoracearum is up to 66.7%~88.9% and 50.0%~88.9% separately.The Erysiphe graminis from Rumex japonicus ,Fatoua villosa ,Clinopodium chinense ,Mirabilis jalapa and Helianthus annuus can result in tobacco powdery mildew also and the infection rate is 5.6%~50.0%.The Erysiphe graminis from Nicotiana tabacum ,Mirabilis jalapa ,Clinopodium chinense ,Helianthus annuus and Fatoua villosa can infect tobacco at stacking stage and loading stage during the tobacco curing process only and the infection rate is 5.6%~88.9%.
