Bacterial blight (barley) : ウィキペディア英語版 | Bacterial blight (barley) Bacterial blight is a disease of barley caused by the bacterial pathogen ''Xanthomonas campestris'' pv. ''translucens'' (syn. ''X. translucens''). It has been known as a disease since the late 19th century. It has a worldwide distribution.〔 〕〔 〕 == Symptoms ==
The disease is characterized by small, pale green spots or streaks which soon appear water-soaked. The lesions expand and then appear as dry dead spots. The lesions elongate into linear streaks which may eventually extend the full length of the leaf. Lesions rarely occur on the leaf sheath or culm. In severe infections, a milky gray exudate may be squeezed from the cut end of leaf exhibiting symptoms.
