小麦矮腥黑穗病菌[Tilletia contro-versa(Kuhn)]在美国,苏联广大地区,在巴尔干,在德国地势较高的小麦栽培地区,是为害小麦的真菌。由于小麦栽培的精耕细作及随之产生的轮作的“减少”,在许多栽培地区,地上厚垣孢子的污染,明显增加。矮腥孢子在地里可以存活几年。麦苗受侵染几乎都是从土壤引起的。所以显然用种子处理剂很少能获得预期的结果。所以对矮腥的防治问题还没有满意的解 Tilletia contro-versa (Kuhn) is a wheat-harden fungus in the United States, extensive areas of the Soviet Union, in the Balkans, and in the more rugged wheat-growing areas of Germany. Due to the intensive cultivation of wheat cultivation and the consequent “reduction” of crop rotation, the contamination of the chlamydospores on the ground is significantly increased in many cultivation areas. Dilly spores can survive in the ground for years. Almost all wheat seedlings are infested from the soil. So it is clear that the seed treatment agent seldom achieves the expected result. So there is no satisfactory solution to the problem of prevention and control of dingy fish
