Description

一种可用于可湿性粉剂的专用助剂组合物
技术领域
本发明属于农药制剂领域，具体涉及一种可湿性粉剂专用助剂组合物 WP-03。
背景技术
在农业病虫害防治过程中，目前大多使用的常规喷施农药药液，当药液 喷洒到作物表面上时，仅有20-30％药液展铺于作物叶面，其它70-80％药液因 展着、内吸性能较差形成大液滴滚落于田间，因而造成农药利用率，农药亩 用量增加，病虫害防效低，污染环境等问题。
农药可湿性粉剂是农药制剂中历史悠久、技术比较成熟、使用方便的一 种剂型,它是由农药原药、表面活性剂(润湿剂、分散剂等)、辅助剂(稳定剂、 警戒色等)、载体和填料等组成并粉碎得很细的农药制剂。可湿性粉剂用水稀 释成田间使用的浓度时,能够形成一种稳定的、可供喷雾的悬浮液。可湿性粉 剂用水稀释后能在防治对象上达到较大的均匀覆盖。我国生产可湿性粉剂农 药已有几十年的历史，但是可湿性粉剂农药结块、悬浮率低、润湿时间长的 问题一直困扰着广大农药生产企业，多数厂家往往由于上述问题的存在使得 农药的稳定性差，效果并不理想，药效发挥不好，浪费了原药及助剂，增加 了农业生产成本。
因此急需开发一种增效助剂组合物以解决现有技术中可湿性粉剂存在 的各种问题。
