农药的分散除依赖机械的破碎和剪切作用外(此处指喷撒机具的作用),还有赖于助剂的辅助作用,药液中加某种表面活性物质,可提高药液在雾化时的分散度,改善药液对植物和昆虫体表的湿润能力,增加农药的粘着性,提高农药在生物靶标上的沉积量,因而显著的提高防治效果.1990年,作者在防治小麦赤霉病时,研究了在多菌灵药液中加入表面活性剂拉开粉后对药液沉积
In addition to the dispersion of pesticides rely on the role of mechanical crushing and shearing (here refers to the role of spraying equipment), but also depends on the auxiliary role of additives in the liquid plus a surfactant, can improve the liquid atomization When the degree of dispersion to improve the ability of plants on the surface of plants and insects moisturizing ability to increase the adhesion of pesticides and improve the deposition of pesticides on biological targets, which significantly improve the control effect.In 1990, the author in the control of wheat scab Disease, the study of the carbendazim liquid surfactant added to open the powder deposited on the liquid
