Application of soft Water for Pesticide dilution

(agricultural Wealth Network) in the prevention and control of diseases and insect pests, because some farmers do not pay attention to diluting pesticide water, pesticides can not play their due role in prevention and control, resulting in failure or even drug damage, resulting in losses to agricultural production. As we all know, water can be divided into hard water and soft water. The so-called hard water refers to well water, salt water, sea water and other substances containing more calcium, magnesium and other substances, the hardness is generally 18-20 degrees. If the pesticides are diluted with these water, the calcium, magnesium and other substances contained in the water can reduce the suspension rate of wettable agents or synthesize calcium and magnesium precipitates with emulsification in EC, destroying the emulsifying performance of EC, which will not only reduce the prevention and control effect of pesticides, but also cause drug damage. Soft water, such as 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 agent and reduce the control effect.
