烟草靶斑病发生规律及防治技术研究进展

Research Progress on the Occurrence Rules and Prevention and Control Technology of Tobacco Target Spot

烟草靶斑病是近年来国内烤烟生产中出现的一种叶部病害。病害发生时,叶片病斑部位穿孔、破烂,甚至失去采烤价值。该病流行迅速、再侵染频繁、危害性大,并有一定的传染性,在重庆、贵州、四川、湖南等烟区均有发生,甚至有大流行趋势,给烟草生产带来严重打击。本文综述了国内外对烟草靶斑病的研究成果,包括烟草靶斑病病原菌生物学特性、发生规律和防治技术,以期为烟农正确识别烟草靶斑病、及时开展烟草靶斑病的预防及防治工作提供参考,从而降低烟草靶斑病造成的损失。

Tobacco target spot is a leaf disease that has appeared in domestic flue-cured tobacco production in recent years.When the disease occurs,the leaf lesion site become perforated,tattered,and even lose their value for harvesting and baking.The disease is rapidly prevalent,frequently reinfected,highly harmful,and has a certain degree of infectivity.It has occurred in tobacco areas such as Chongqing,Guizhou,Sichuan,Hunan,and even has a pandemic trend,bringing a serious blow to tobacco production.In this paper,the research achievements of tobacco target spot at home and abroad were reviewed,including the biological characteristics of pathogenic bacteria,occurrence rules and prevention and control technologies of tobacco target spot,in order to provide reference for tobacco farmers to correctly identify tobacco target spot,timely carry out the prevention and control of tobacco target spot,and reduce losses caused by tobacco target spot.
