在吉林省调查了柳河、蛟河、龙井等九个主要烟草产区,发现有四种细菌病害。经对其症状的观察和对病原细菌的系统鉴定,确认病斑周围具有宽晕的是烟草野火病,病斑多角形而无晕圈的是烟草角斑病。这两种病害的病原菌分别为 Pseudomonas syringae Pv·tabici的两个不同的菌系,即产生野火毒素的菌系和不产生野火毒素的菌系。病斑不规则形,排列于叶脉两侧为主的是烟草细菌性叶斑病,病原细菌为 Xanthomonas campestris PV·vesicatoria。主要危害茎部,使髓部腐烂,茎中空,叶片萎蔫腐败的是烟草软腐病,病原细菌为 Erwiniacarotovora subsp carotovora。其中烟草野火病和角斑病只在柳河县发现.另两种病害则较普遍。
In Jilin Province, Liuhe, Jiaohe, Longjing and other nine major tobacco producing areas were investigated and four bacterial diseases were found. After the observation of its symptoms and the systematic identification of pathogenic bacteria, it was confirmed that there was a broad halo around the lesion, which was tobacco wildfire, polygon of lesion and no halo. The pathogens of these two diseases are respectively two different strains of Pseudomonas syringae Pv. Tabici, namely wild-type toxin-producing strains and wild-type toxin-producing strains. Irregular lesions, arranged on both sides of the vein are tobacco bacterial leaf spot, pathogenic bacteria Xanthomonas campestris PV vesicatoria. The main harm to the stem, the decay of the stem, hollow stems, leaf wilting corruption is tobacco soft rot, the pathogenic bacteria Erwiniacarotovora subsp carotovora. Among them, tobacco wildfire and angular leaf spot were only found in Liuhe County, while the other two diseases were more common.
