摘　　要：通过对烤烟棒孢霉叶斑病病原菌越冬规律的研究,结果,南瓜、豇豆、辣椒、番茄和茄子等作物在大田生产中感染烤烟棒孢霉叶斑病菌的可能性小,随病株种子及碎屑越冬的病菌很少,杂草作为烤烟棒孢霉叶斑病病菌来源的作用亦是次要的,带菌烟秆才是病菌的主要越冬场所。The results from investigating the overwintering regulation of pathogenic fungi of Corynespora cassiicola-leaf spot indicate that the main overwintering place of pathogenic fungi of Corynespora cassiicola leaf spot is at the tobacco sterns with the pathogenic fungi, weeds is the second source of pathogenic fungi of Corynespora cassiicola leaf spot, seeds and particles from severely deseased tobacco plant is slightly infected by Corynespora cassiicola leaf spot and the vegetable crops such as pumpkin, China bean, pepper, red bean, tomato and eggplant is not almost infected by Corynespora cassiicola leaf spot.
