散黑穗病是黑龙江省春小麦的主要病害之一,当地主要推广品种普遍感病,病穗率一般在1—5%,个别年份,感病重的品种可达10%以上。过去推行温汤浸种或石灰水浸种,配合隔离繁殖,收到一定防治效果,但繁杂费时,温度不易控制,掌握不好,种子发芽力会明显降低。近年来,通过试验筛选出了一些高效、广谱、内吸杀菌剂,用来拌种防效明显,方法简便,推广使用后,有效地控制了小麦散黑穗病。主要拌种药剂有: Scattered smut is one of the major diseases of spring wheat in Heilongjiang Province. The prevalence of the disease is generally 1-5% in most local popularized varieties. In some years, the susceptible varieties can reach more than 10%. In the past the implementation of warm soaking soup or lime soaking, with isolation and breeding, received a certain control effect, but cumbersome and time-consuming, temperature is not easy to control, control is not good, the seed germination will be significantly reduced. In recent years, some high-efficiency, broad-spectrum and systemic fungicides were screened out through experiments to control the effect of seed dressing obviously and the method is simple and convenient. After the popularization and application, the smut control of wheat was effectively controlled. The main seed dressing agents are:
