小麦白粉病是我州小麦普遍发生、为害严重、发病期长的一种常见病,严重影响小麦正常生长与结实。一般减产1—3成,严重时减产竟高达4—5成,白粉病已成为小麦生产上的严重威胁。由于我州气候条件较适合白粉病发生,加上当前栽培推广的小麦品种一般抗病力不强,采用药剂防治白粉病,就成为夺取小麦大面积高产的重要措施之一。 Wheat powdery mildew is a common disease of wheat in our country, causing serious damage and long period of disease. It seriously affects the normal growth and fruiting of wheat. Generally reduce the production of 1-3 into, in severe cases cut as much as 4-5 into production, powdery mildew has become a serious threat to wheat production. As the climate conditions in our country are more suitable for powdery mildew, coupled with the current general resistance to wheat cultivars are not strong, the use of pesticides to control powdery mildew has become one of the important measures to capture large areas of wheat yield.
