Diluted pesticides with soft water

As we all know, water is divided into hard water and soft water. The so-called hard water refers to wells, salty water, seawater, etc. contain more calcium, magnesium and other substances, the hardness is generally 18 to 20 degrees. If these waters are used to dilute the pesticides, calcium, magnesium and other substances in the water can reduce the suspension rate of the wettable agents or synthesize calcium and magnesium precipitates with the emulsifiers in the emulsifiable concentrates to destroy the emulsifying properties of the emulsifiable concentrates. This will not only reduce the control of pesticides. Effect, but also produce phytotoxicity. Soft water, like river water, lake water, and other fresh water, contains less calcium and magnesium, and its hardness is about 7.5 degrees. It will not destroy the performance of the drug and reduce the control effect.
