据国外报道,小麦雪霉病早在北美、北欧和亚洲等地发生,而以北欧和亚洲地区为严重。我国最早发生在新疆北部,是该地冬麦苗期的重要病害之一。之后,陕西也相继发生。近年来,江苏、江西等省均有所发现,但各地所用名称不一。如新疆陕西称为小麦雪霉病,江西暂定名为小麦叶斑病,江苏称为小麦雪腐叶斑病,西北暂定名为小麦镰刀轮斑病。我们也暂称之为小麦雪霉病。 According to foreign reports, wheat snow mildew occurred as early as in North America, northern Europe and Asia, while in North Europe and Asia is serious. China first occurred in the northern part of Xinjiang, which is one of the important diseases of winter wheat in this area. After that, Shaanxi also happened one after another. In recent years, Jiangsu, Jiangxi and other provinces are found, but the names used in different places. Such as Xinjiang, Xinjiang called wheat snow mildew, Jiangxi tentatively known as wheat leaf spot, Jiangsu known as wheat snow leaf spot disease, the Northwest tentatively known as wheat sickle leaf spot disease. We also temporarily call the wheat snow mildew.
