Master correct pesticide dilution methods to ensure efficacy. Preventing pollution has an important role. The method of operation is as follows: When the amount of diluted liquid liquid pesticide is small, it can be directly diluted. The correct method is to fill the required clean water in the prepared medicine container, then slowly pour the quantitative medicine into the water, and use it with a wooden stick or the like to mix gently. If you need to make more liquid volume. It is best to adopt a two-step preparation method: first, dilute the original pesticide solution with a small amount of water into a mother liquor, and then pour the prepared mother liquor into the prepared fresh water according to the dilution ratio, and mix thoroughly evenly. The wettable powder is diluted by a two-step preparation method, ie, a relatively small amount of water is used to prepare a relatively thick mother liquor and then poured into a container containing water for final dilution. However, it should be noted that the amount of water used for the two-step preparation should be equal to the theoretical amount of water used. Dilution of powdered pesticides is mainly done with fillers. First take the filler (grasswood ash, coal ash, rice bran, etc.) Mix the required powder pesticide into the mix, and then add it repeatedly until it reaches the required multiple. Dilutions of granule pesticides are mixed with appropriate fillers. When diluted, dry soft soil or homogenous fertilizer can be used as the filler, and the mixture can be evenly stirred in a certain proportion.
