提高农药产品效率的药效增强剂(Ⅰ)

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.

Enhancer of Increasing Pestcide Products Efficacy(Ⅰ)

This paper describes that enhancer can improve pesticide products efficacy through increasing spray droplet wetting, spreading, retention, penetrating and uptake in plant species. Enhancer can be classified into types: surfactant, oils, polymers, inorganic salts and waxes and so on. So both the physicochemical properties of pesticide products and the leaf surface characters of plant species need to be considered in selecting enhancer. Surfactant was the most widely used of enhancer. Effect of surfactants on...
