细菌病害在各种植物上都可以发生,只是种类不如真菌病害那样多。重要的细菌病害,如水稻白叶枯病、水稻细菌性条斑病、黄瓜细菌性角斑病、白菜软腐病、辣椒青枯病、柑橘溃疡病、烟草青枯病、姜瘟病等,都给生产造成过严重损失。由于细菌没有主动侵染植物的能力,传播、侵染都与水关系密切,所以田间可以看到病害随流水或雨滴飞溅传播的分布格局;淹水和暴风雨往往会造成细菌病害的大流行。这可以从时间顺序上取得旁证。 Bacterial diseases can occur on a variety of plants, but not as many as fungal diseases. Important bacterial diseases such as rice bacterial leaf blight, rice bacterial leaf streak, bacterial angular leaf disease cucumber, cabbage soft rot disease, pepper bacterial wilt, citrus canker, tobacco bacterial wilt, blast, etc. To produce a serious loss. Because bacteria have no ability to actively infect plants, the spread and infection are closely related to water, so the distribution of diseases along with running water or raindrops can be seen in the field. Flooding and storms often result in bacterial disease pandemics. This can be circumstantial evidence.
