在1977—1978年生长季节,种植在旁遮普省农业大学试验农场的几个小麦品种在腊熟期严重地感染了颖枯病。病害的特征初期表现为紫褐色椭圆形病斑,后期转为灰色。严重感染颍枯病的植株,其病斑有时几乎完全被黑色的孢子群所复盖,甚至有时感染到芒上。在高度感病的品种上,穗轴上复盖了一层暗褐色病斑,叶面呈 During the 1977-1978 growing season, several wheat cultivars planted at the pilot farm at Punjab Agri-Agro University were severely infected with Z. crassifolia during the ripening stage. Disease characteristics initially manifested as purple brown oval lesions, later turned to gray. Plants that are severely infected with blight can sometimes be spotted almost completely with black spore colonies and sometimes even with mans. On highly susceptible varieties, the cob covered a dark brown lesion with a foliar appearance
