摘　　要：[目的]鉴定四川烟草上的一种叶斑病害,并探讨其防治技术。[方法]采用"柯赫氏法则",对2012年在四川会东育苗温室红花大金元上发现的一种叶斑病害进行了鉴定,并研究了几种药剂对该病菌的防治效果。[结果]依据病害症状和病原形态特征确认为烟草炭疽病菌(Colletotrichum nicotianae Averna-Sacca);75%百菌清600倍稀释液、80%代森锌800倍稀释液、80%代森锰锌800倍稀释液、50%退菌特800倍稀释液、50%福美双500倍稀释液对炭疽病有较好的防治效果。[结论]为烟草炭疽病的防治提供了参考。[Objective] The aim was to identify a leaf spot disease occurred in seedbed on‘Honghuadajinyuan＇in Sichuan Province in 2012 and explore its control technology. [Method] A leaf spot disease occurred in seedbed on ‘Honghuadajinyuan＇in Sichuan Province in 2012 was identified by Koch＇s Rule,and control effects of several regents on it were studied. [Result] The pathogen was identified as Colletotrichum nicotianae Averna-Sacca according to symptom on tobacco leaf and pathogen shape. The fungicides trial in greenhouse showed that the five fungicides like 75% Chlorothalonil 600 times,80% Zineb 800 times,80% Mancozeb 800 times,50% Tuzet 800 times and 50% Thiram500 times could control this disease. [Conclusion] The results provide reference for control of tobacco anthracnose.
