摘　　要：针对临沧新烟区烟草花叶病、赤星病等病害普遍发生的生产实际问题,开展了青霉菌灭活菌丝体、枯草芽孢杆菌和哈慈木霉菌在烤烟上的抗性比较研究,选取这3种药剂在烤烟大田期进行施药,观察各药剂的防治效果.结果表明,4个采用生物防治措施的处理均对烟草花叶病、赤星病具有显著的防控效果,其中"青霉菌灭活菌丝体+枯草芽孢杆菌+哈慈木霉菌"组合处理对烟草花叶病、赤星病防控效果最好,相对于空白对照防效分别为92.35%和55.12%,相对于化学药剂防效分别为13.0%和4.7%.Considering the tobacco mosaic virus (TMV)and brown spot disease prevailing in Lincang new tobacco-growing area,organic induced resistant agent (DMP),Bacillus subtilis and Trichoderma harzianum were studied comparatively on flue-cured tobacco resist-ance.Three kinds of selected organic induced resistant agent (DMP),Bacillus subtilis and Trichoderma harzianum are used in flue-cured tobacco fields to observe the control effect.The result shows that four methods all have significant effect on the tobacco mosaic virus (TMV)and brown spot disease.Among which DMP +Trichoderma harzianum +Bacillus subtilsi performed best on TMV and brown spot disease with a control effect of 55.1 2% comparing with blank control effect for brown spot disease and 92.35% for (TMV), with a control effect of 4.7% comparing with chemical control effect for brown spot disease and 1 3.0% for (TMV).
