小麦细菌性条斑病是我省河西地区小麦重要病害之一,对小麦产量,品质都有很大影响。据调查一般感病品种发病率为20—40％,严重地块高达100％,病株千粒重下降14.4—27.5％。病原与小麦黑颖病病原基本相同。症状: 小麦细菌性条斑病在自然条件下,主要危害叶片,有时也危害叶鞘和颖壳。被害叶片初期出现暗绿色水渍状小斑,其后因受叶脉限制,病斑可纵向扩展形成油浸状褐色条斑,并有
Wheat bacterial leaf streak is one of the important diseases of wheat in the Hexi area, which has a great impact on wheat yield and quality. According to the survey, the incidence rate of common susceptible varieties is 20-40%, the massif is as high as 100% and the weight of diseased plants is reduced by 14.4-27.5%. The pathogen is basically the same as that of wheat black-eyed. Symptoms: Wheat bacterial leaf streak, under natural conditions, harms the leaves and sometimes the leaf sheaths and glumes. Victims of the early leaves of dark green water-like small spots, then due to the limitations of the veins, lesions can be longitudinally expanded to form oily brown streaks, and
