| 摘 要： | 近年河北省谷锈病逐年加重,给夏谷生产造成严重损失,尤其发病早的地块减产较重,甚至绝收。该病在夏价产区田间流行呈典型的“Ｓ”开曲线。病害流行与否阳决于夏谷生育期的雨量、雨次及其分布,夏谷品种抗病性和环境。防治技术为播种前处理还病谷草,大面积种植抗病品种,多雨年份在发病中心形成期喷药防治。

| Abstract: | The millet rust has been becoming more serious in recent years in Hebei Province. It makes great losses to millet productionlesp. in the fields where the disease oc-cur earlier, the loss is heavier, even without gains. In main millet-production area, the dis-ease epidemic curve is typical "S" type. The epidemic degree deponds on the factors such as rainfall, rain times, resistance of millet varieties, and environment. The controlling methods are: removing diseased millet straw before sowing, planting resistant varieties widely,spraying pesticide in th diseased area during the forming period. |
