What are the characteristics of soft water? What are the characteristics of hard water? Why can't hard water be used to dilute pesticides? Gengzhongbang Planting Network gives a brief introduction below for netizens' reference.Water is divided into hard water and soft water. So-called hard water refers to water such as well water, brackish water, seawater and the like that contains relatively large amounts of calcium, magnesium and other substances, with hardness generally at 18-20 degrees.
Soft water refers to fresh water such as river water and lake water, which contains relatively little calcium, magnesium and other substances, with hardness at around 7.5 degrees.
The main reason hard water cannot be used to dilute pesticides is that the calcium, magnesium and other substances contained in the water can reduce the suspension rate of wettable powder formulations or combine with emulsifiers in emulsifiable concentrates to form calcium-magnesium precipitates, destroying the emulsifying performance of the emulsifiable concentrate. This will not only reduce the control effect of the pesticide, but also cause phytotoxicity. Soft water contains relatively little calcium, magnesium and other substances, so it will not destroy the performance of the pesticide or reduce the control effect.
