The secondary dilution of pesticides is also called a two-step formulation method and is one of the methods of pesticide formulation. After the pesticides are diluted twice, they can make certain insoluble powders or small amount of pesticides dissolved more completely and more evenly distributed, making the measurement more accurate, improving the effect of drug use and reducing the occurrence of drug injury. , but also reduce the risk of exposure to the original drug poisoning. The following methods can be used for secondary dilution of pesticides.
A. Use a medical saline bottle with a volume scale, place the drug in a bottle, inject a suitable amount of water, and mix it into a mother liquor, and then use a measuring cup for measurement.
B. When using a knapsack sprayer, it is also possible to carry out secondary dilution directly in the pail. First add a small amount of water to the sprayer, add a little liquid, shake it well, and then make up for the water and mix it up.
C. When a large-area spray is applied to a motorized sprayer, a larger amount of containers, such as barrels and cylinders, may be used for the first-stage dilution of the mother liquor. The secondary dilution can be formulated in a sprayer pail and mixed for use.
Note: In order to ensure the dilution quality of the liquid, the amount of water used to prepare the mother liquor should be carefully calculated and carefully measured, and should not be used arbitrarily or with little use, otherwise it will directly affect the control effect.
