Usually, well water is used for pesticide application. Because of the shortage of tap water in rural areas, well water is basically used. Generally speaking, well water is alkaline. Adding a little vinegar can neutralize alkalinity. If the water is neutral, pesticide is the best. Vinegar contains some substances such as acetic acid and amino acids. After spraying these substances on leaves, they can first adjust the photosynthesis of leaves, and then stimulate the growth of crop leaves. Another point is that vinegar has the function of sterilization and disinfection. When the amount of liquid is small, it can be diluted directly.
Add the required clean water into the prepared dispensing container, then gradually pour a certain amount of medicine into the water and gently stir it with a wooden stick. When more doses need to be prepared, it is best to adopt two-step preparation method; That is, a small amount of water is used to prepare the mother liquor of pesticide stock solution, and then the prepared mother liquor is poured into the prepared clear water according to the dilution ratio and can be used after being evenly stirred. A two-step preparation method is adopted, that is, a small amount of water is used to prepare concentrated mother liquor, and then it is poured into a container containing water for final dilution. It should be noted that the water required for two-step preparation should be equal to the theoretical water consumption.
Don't use sewage to dispense medicine, there are many impurities in sewage. The dispensing nozzle is easily blocked, which will also destroy the reagent suspension and produce precipitation. Don't use well water to dispense medicine. Well water contains a variety of minerals, which are easy to produce chemical reactions after being mixed with pesticides, forming precipitates and reducing the efficacy. It is best to fill the medicine with clean river water. According to different crop types, control objects and pesticide properties, use corresponding pesticides. To really suit the remedy to the case, the abuse of pesticides often causes phytotoxicity. ?
