The comprehensive prevention and control of diseases and pests at the ear of wheat is mainly combined with the control of the control of head blight diseases such as powdery mildew, panicle blast, and planthoppers. The control effect of wheat scab is mainly determined by the time when the medicine is used for the first time. Usually, the best application time is the flowering period. Generally, wheat is first raised after heading and should be used when it is 10%-50% of the flowering time; high temperature at the heading stage, and wheat heading at the heading side should be applied to the heading stage in advance. Whether or not the drug is used when wheat is heading 70% should be determined according to the climate. If the temperature is normal and there is no continuous rainy weather in the later period, you can wait until the early stage of flowering. If the temperature is high during the panicle stage or there is rainy weather, you can use the medicine immediately when the heading is 70%.
