Abstract

一种苗前除草剂,它由下列组分构成:2.4－D丁酯10－50份、嗪草酮5－50份,这种新型的除草剂对作物安全,对下茬作物无影响,可广泛作为大豆、玉米的苗前除草剂。

Description

苗前除草剂
本发明涉及一种能同时用于大豆、玉米田苗前除草剂及其生产方法。
目前，广泛用于大豆、玉米田的苗前除草剂主要有三氮苯类、磺酰脲类、酰胺类、有机杂环类、咪唑啉酮类等，在使用过程中多以二元或三元混配来扩大杀草谱以达到一次使用防除全部杂草的目的，存在的问题是上述各类除草剂单用或混用均不同程度地存在着对当茬或后茬作物有影响的缺点，解决这一问题已成为急需。
本发明的任务是：克服现有技术的不足，提出一种对作物安全，对下茬作物无影响，用量小，防效好，安全性高的苗前除草剂及其生产工艺。
本发明的任务是以如下方式实现的：苗前除草剂由下列成份构成：2.4—D丁酯10—50份、嗪草酮5—50份，其它为助剂和溶剂。
将上述两种成份混合均匀即可。
本发明由于成份中含有2.4—D丁酯和嗪草酮，因此对农田中的阔叶杂草防效达80—90％，同时还具有对作物安全、持效期长，对下茬作物无影响，成本低，使用方便，实现用量小，防效好，安全性高，是理想的大豆、玉米田苗前除草剂。
本发明的一个最佳实施例，苗前除草剂由下列组分组成：2.4—D丁酯10kg、嗪草酮50kg，助剂和溶剂40kg，混合均匀即为成品。
本发明的第二个实施例，取2.4—D丁酯50kg、嗪草酮5kg，助剂和溶剂55kg，混合均匀即为成品。
