Due to long-term low temperature and rain, many wheat fields do not have weeds. At present, the wheat has entered the jointing stage. The weeds in the field are mainly precocious and aphrodisiac. What kind of medicine should be used to prevent it?
After the jointing of wheat, it is generally not appropriate to reuse herbicides to remove grassy weeds. If wheat is in the early stage of jointing, the number of weeds in the field is large, and if it does not result in a serious reduction in yield, we can consider the use of isoproterenol in addition to precocious puberty and aphrodisiac. When the grass age is large, the dosage should be increased appropriately. According to the growth of wheat seedlings, the amount of 50% isopropanol WP can be increased to 150-250 grams. Looking at the seriousness of Aphrodite, consider using isoproturon with clodinafop.
Tip: Poa plant is short, wheat grows quickly after jointing, and can quickly gain competitive advantage, so after the jointing of wheat can be considered without precocious drugs. When wheat seedlings are thin and weak, fertilizers can be added appropriately.
