In the absence of deforestation in the last winter and severe field crops in the field, we should take precautions during the spring. As the spring wheat turns green, the time for the appropriate removal is relatively tight, and the temperature is unstable. The improper use of herbicides is prone to phytotoxicity. Therefore, the following points must be noted when using drugs: 1 The spraying time must be controlled before the wheat turns green and before the jointing. The daily average temperature is stable at more than 10 degrees. After the jointing of wheat, no chemical herbicide can be used to prevent the occurrence of injury. 2 Before the application, pay attention to the change of the weather. If there is a strong temperature drop within 2 to 4 days before the application, it is not appropriate to use drugs. 3 Strictly control the amount of drugs used, can not arbitrarily increase or decrease, for some new herbicide species, must not blindly use. 4 It should be even and thoughtful when spraying, so as not to spray or re-spray. 5 Select the correct herbicide type based on the type of weeds in the field.
