When is the best application time to prevent wheat scab?

Wheat scab is most likely to occur at heading and flowering stage, that is, from mid-April to mid-May, so the control effect at this stage is generally good. Prevention should be given priority to wheat scab. If infected at flowering stage, serious consequences may occur at filling stage, and it is difficult to prevent the disease from happening at this time.

Wheat scab usually occurs at heading stage and flowering stage, and the time is generally between April 15 and May 10. Due to the climate differences in different places, the time is slightly different, so we should carefully control the heading and flowering stages of wheat.

Because wheat scab is infected at flowering stage, serious consequences do not appear until filling stage, and it is difficult to control after the onset, so prevention is generally the main thing. However, wheat scab is generally prevalent in rainy weather, so we must seize the key period of wheat scab control.

Extended data:

Precautions:

1, the temperature at heading stage is high, and wheat can be sprayed at heading stage while flowering.

2. Low temperature and less sunshine at heading stage. Wheat should be sprayed at flowering stage after heading.

3. If it is predicted that there will be rainy, dewing or foggy weather for more than 2 days at the flowering stage of wheat, the first application time should be appropriately advanced to the full heading stage, and 1-2 times every 5-7 days after the first control, so as to ensure the control effect.

4. If the chemicals with good internal absorption and long duration are sprayed, it can be prevented in advance at heading stage.
