The best time to spray herbicide
It is safest to spray herbicide about 40 days after sowing, when the wheat is in the 4-leaf or 4-leaf 1-heart stage, and the resistance to herbicide is high, which is relatively safe. In addition, the weeds in the field have been out at this time, and the grass age is small, the drug resistance is poor, and the weeds are safe and efficient.
