论述药效增强剂通过改善农药产品性能,增强喷雾液滴在靶标上的润湿、展布、滞留、渗透和吸收从而提高药效。药效增强剂类型包括表面活性剂、油类、聚合物类、无机盐类和蜡类等。选择药效增强剂时,不仅要考虑农药产品的理化性质,还要考虑靶标植物的表面特性。在药效增强剂中应用最多的是表面活性剂;指出表面活性剂对吸收的影响更为复杂,与其亲水基和亲脂基结构和浓度均有关。
Efficacy enhancers discussed by improving the performance of pesticide products and enhance the spray droplets on the target wetting, spreading, retention, penetration and absorption to improve efficacy. Efficacy enhancer types include surfactants, oils, polymers, inorganic salts and waxes. When selecting efficacy enhancers, not only the physicochemical properties of the pesticide product but also the surface properties of the target plant should be considered. The most commonly used surfactant in the efficacy enhancer is the more complex effect of surfactant on absorption, which is related to the structure and concentration of hydrophilic and lipophilic groups.
