烟草棒孢霉叶斑病的综合防控研究进展

Research Progress on the Comprehensive Prevention and Control of Tobacco Corynespora Leaf Spot

多主棒孢霉(Corynesporacassiicola)入侵烟叶会导致烟草棒孢霉叶斑病.烟草棒孢霉叶斑病在我国六大烟区均有发生,其中贵州省、广西壮族自治区烟区最严重,严重限制我国烟草产业的发展.通过分析烟草棒孢霉叶斑病的研究情况,整理关于多主棒孢霉类型特点、病原病害特点、病害流行规律及其主要防治技术的研究与进展,为烟草棒孢霉叶斑病的有效防治提供依据.研究发现,混合药剂比单一药剂对烟草棒孢霉叶斑病防控效果更好,但是单一的化学防控方法并不是我们的主要目标,绿色综合防控治理才是主要的研究方向,而我国在这一方面还处于初始阶段.

Corynesporacassiicola invades tobacco leaves, causing tobacco Corynespora leaf spot. Corynebacterium leaf spot disease occurs in six major tobacco areas in China, of which Guizhou and Guangxi tobacco producing areas are the most serious, severely restrict the development of China’s tobacco industry. By analyzing the research situation of tobacco Corynespora leaf spot, previous reports on the typecharacteristics of Corynesporacassiicola, pathogenic disease characteristics, disease epidemic rules and its main prevention and control technologies were sorted out, which provided a basis for the effective prevention and control of tobacco Corynespora leaf spot. Combined agents are more effective than single agents for the prevention and control of tobacco Corynespora leaf spot. However, the chemical only prevention and control method is not our main purpose, but green comprehensive prevention and control management is the main research direction. Our country is still in initial stage in this regard.
