摘  要:
通过小区对比试验,研究了生防菌剂对烟草主要土传病害的防治效果。结果表明:生防菌剂XE01与X23能有效降低烟草青枯病发病几率和发病程度,其中施用生防菌剂XE01 7500 m L/hm~2+X23 4500 m L/hm~2处理,在打顶期和中部叶采收期防效较72%农用硫酸链霉素5000倍液分别提高了11.17%、13.53%,具有较好的推广应用价值。生防菌剂虽能在一定程度上降低烟草黑胫病发病几率和发病程度,但其防治效果与72%甲霜·锰锌相比还有一定的差距。

摘  要:
Field contrast test was conducted to study the control effects of bio-control agents on major soil-borne diseases of tobacco. The results showed that: the bio-control agents XE01 and X23 were more effective than streptomycini sulfas in the control of tobacco bacterial wilt. It reduced the incidence and disease severity of tobacco bacterial wilt. Compared with 72%streptomycini sulfas treatment,by using bio-control agents XE01 7500 m L / hm~2+ X23 4500 m L / hm~2,the control effect increased 11. 17 percentage in the topping stage,and 13. 53 percentage in the middle leaves harvesting stage. The bio-control agents have better value of application and dissemination. Although the bio-control agents XE01 and X23 could reduced the incidence and disease severity of tobacco black shank,but compared with the chemical agent of 72% ridomil-MZ,the control effect was still had a certain distance.
