Scald is common disease of barley in temperate regions. It is caused by the fungus ''Rhynchosporium secalis'' and can cause significant yield losses in cooler, wet seasons.〔 〕〔 〕 == Symptoms == Scald is a foliar disease of barley affecting the leaves and sheaths of the plant; however, lesions may also occur on coleoptiles, glumes, floral bracts and awns. Initial symptoms are oval, water-soaked, grayish-green spots, 1.0-1.5 cm long. As the disease develops, the centers of the lesions dry and bleach, becoming light gray, tan, or white with a dark brown margin. The lesions are not delimited by the leaf veins and often coalesce. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Scald (barley disease)」の詳細全文を読む スポンサード リンク
