为了增加农药的展着力,提高农药对病虫害的防治效果,许多果农常在稀释的农药中掺入肥皂水和洗衣粉。这些碱性物质与某些农药如水胺硫辨、乐果、敌敌畏、杀虫双、代森锌等混合后,往往影响农药的稳定性,降低防治效果。我们于1984—1985年,在福鼎县前岐果场采用不同剂量的褐藻酸钠(福建省福鼎县化工厂产品)作为展着剂掺入农药,进行
In order to increase the spread of pesticides and improve the control effect of pesticides on pests and diseases, many fruit growers often incorporate soapy water and detergent into diluted pesticides. These alkaline substances and certain pesticides such as water amine sulfur discrimination, dimethoate, dichlorvos, insecticidal double, dexamethasone and other mixed, often affect the stability of pesticides and reduce the control effect. In 1984-1985, we used various dosages of sodium alginate (Fuding County Chemical Plant in Fujian Province) as a spreading agent in Qianqi fruit farm in Fuding County,
