The first is to look at the production date and shelf life before the use of drugs, the deadline has not yet reached the amount should be used strictly according to the instructions; the time has passed, according to its efficacy should increase the dosage. As soon as some pesticides have expired, the efficacy will be greatly reduced; some pesticides have expired, but their efficacy remains basically unchanged. Therefore, in the use of expired pesticides, the first use of the amount must be sprayed according to the amount of instructions, use 3-5 days after the observation of their pest killing effect. If the effect is not obvious, it is necessary to increase the dosage on the basis of the original; if the effect after the second spray is not obvious, it is necessary to change the pesticide or use pesticides alternately; if the effect is obvious, the efficacy is still maintained, follow the instructions. Dosage continues to use.
Second, master the dosage according to the crop growth stage. Especially in the seedling stage of the crop, the leaf area is small, the amount of medication should be reduced accordingly, but the spraying of pesticides should still be used according to the proportion of the amount of matching. Other phases, such as overdue pesticides, can increase their dosage in moderation.
Third, pesticides should be sprayed evenly. When pesticides are sprayed, the syrup must always be kept at the pressure scale of the air chamber. This pressure is so great that the sprayed medicine turns into fine droplets that can adhere to the front and back of the blade evenly. In general spraying, the nozzle is placed under the leaves of the crop, the mouth is up, the front and the back of the blade can be evenly sprayed, do not have to change the position of the nozzle, usually spray one time is better, can not be repeated at the same time, otherwise Prone to injury.
