In the winter of last year, there was no dismantling and serious weeds occurred in the field, and spring should be taken care of during the spring. Since the spring wheat is greened, the time for proper removal is relatively tight, and the temperature is unstable. The improper use of the herbicide is prone to phytotoxicity. Therefore, you must pay attention to the following points when using the medicine:
1 spraying time must be in the wheat before returning to the jointing, the daily average temperature is stable above 10 degrees, after the jointing of wheat, chemical herbicides should not be used to prevent the occurrence of phytotoxicity.
2 Pay attention to the weather changes before applying the medicine. It is not advisable to use the medicine when there is a strong temperature drop within 2~4 days before application.
3 Strictly control the dosage of the drug, can not be increased or decreased at will, for some new herbicide varieties, must not be used blindly.
4 Spray evenly and thoughtfully, so as not to leak or spray.
5 Select the correct type of herbicide based on the type of weed in the field.
