The second dilution of pesticides is also known as the two-step preparation method and is one of the methods for pesticide formulation. The pesticide is prepared by two dilutions, which can make some non-soluble WPs or small amounts of pesticides get more fully dissolved and more evenly distributed, which makes the measurement more accurate, which not only improves the drug effect, but also reduces the occurrence of phytotoxicity. It also reduces the risk of exposure to the original drug poisoning. The pesticide can be diluted twice by the following methods.
How to make a second dilution of pesticides A. Select a medical saline bottle with a capacity scale, place the medicine in the bottle, inject a proper amount of water, prepare a mother liquor, and measure the dosage cup.
B. When using a knapsack sprayer, it can also be directly diluted in the barrel. Pesticide manufacturers recommend adding a small amount of water to the sprayer, then adding a little liquid, shake well, and then make up the water and mix well.
C. When using a motorized sprayer for large-area application, a larger container, such as a barrel or a cylinder, may be used for primary dilution of the mother liquor. In the second dilution, it can be placed in the sprayer barrel for mixing and mixing.
Tips for China Pesticide Network : The water consumption of the mother liquor should be carefully calculated and carefully measured to ensure the dilution quality of the liquid. It should not be added or used at will, otherwise it will directly affect the control effect.
