井水中含有较多的矿物质,如钙、镁等。如果用含钙、镁较高的井水去稀释乐果、马拉松、杀虫脒、敌百虫、甲胺磷等乳油农药时,井水中的钙、镁等物质容易与农药中的乳油结合,产生沉淀物,因而破坏农药的乳化性能,降低农药的使用效果。如果用含钙、镁较高的井水去稀释速灭威、叶蝉散等可湿性粉剂农药时,会降低药液的均匀度,也会影响防治效
Well water contains more minerals, such as calcium, magnesium and so on. If you use calcium and magnesium well water to dilute dimethoate, marathon, chlordimeform, trichlorfon, methamidophos and other EC pesticides, well water calcium, magnesium and other substances easily with pesticide EC, Produce sediments, thus undermining the emulsifying properties of pesticides and reduce the use of pesticides. If you use calcium and magnesium well water to dilute speed off Viagra, leafhoppers and other wettable powder pesticides, will reduce the liquid uniformity, will also affect the control effect
