Answer: Clodinafop-propargyl is used to control grassy weeds in wheat fields. The dosage depends on the size of weeds and the sensitivity to drugs. Sensitive weeds 2 to 4 leaf stage, clodinafop-propellant pure medicinal mu dose 3 ~ 4.5 g can be. When the grass age is increased or when it is necessary to control hard weeds and Japanese aphrodisiacs, we should increase the amount of drug to be used. When the dosage is large, and the dosage of pure medicinal mu exceeds 6 grams, it will have a certain inhibitory effect on the growth of wheat seedlings. When the dosage of pure medicinal mu exceeds 9 grams, it will seriously inhibit the growth of wheat seedlings. Due to waterlogging and other reasons, wheat grows poorly. When the seedlings are small and seedlings are weak, it is more prone to phytotoxicity when the amount is increased. Strong spring wheat seedlings have strong drug resistance and can be applied at appropriate dosages. In addition, the application of clodinafop-propargyl in the short-term can not be a strong cooling temperature and cold weather, otherwise it may increase the injury.
