The pesticide is prepared by two dilutions, which can make some non-dissolvable wettable powders or small amounts of pesticides more fully dissolved, more evenly distributed, and make the metering more accurate, which not only improves the efficacy but also reduces the occurrence of phytotoxicity. It also reduces the risk of exposure to the original drug poisoning.
1. Use 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.
2. When using a knapsack sprayer, it can also be directly diluted in the barrel. First add a small amount of water to the sprayer, add a little liquid, shake well, then make up the water and mix well.
3, when using a motorized spray machine for large-area application, larger containers, such as barrels, cylinders, etc., can 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.
Note: In order to ensure the dilution quality of the liquid, the water consumption of the mother liquor should be carefully calculated and carefully measured. It should not be added or used at will, otherwise it will directly affect the control effect.
