Abstract

本发明公开了一种小麦田除草剂组合物，其特征在于它含有1份-99份(wt)的噻吩磺隆和1份-99份(wt)的唑草酮，并含有可任选的载体，表面活性剂，分散剂和/或农用的辅助剂。本发明将两者复配，解决了小麦田除草剂的单一性。能有效防除小麦田的各种杂草。同时解决了小麦田除草剂速度慢的问题，加速了除草速度。还解决了小麦田除草剂对后茬作物的安全性，其残留期只有一个月。对于后茬种植花生、蔬菜的农民可以放心使用。

Description

一种小麦田除草剂组合物
技术领域
本发明涉及一种小麦田除草剂组合物。
背景技术
目前小麦田除草剂的种类虽然很多，但是这些产品都有着各自的弊端。有的防除禾本科杂草，有的防除阔叶杂草，无法兼顾两种杂草都防除的目的。也有一些复配产品既能防除禾本科杂草又能防除阔叶杂草的除草剂。如：苯磺隆、异丙隆、噻吩磺隆用到小麦田除草彻底，但是除草速度慢。如：苯磺隆+唑草酮的除草剂虽然除草速度快，但是残留期长，后茬种植以花生、蔬菜的田地不能用药，容易产生药害。
发明内容
本发明需要解决的问题就在于提供一种
为解决上述问题，本发明采用如下技术方案：
本发明小麦田除草剂组合物，它含有1份-99份(wt)的噻吩磺隆和1份-99份(wt)的唑草酮，并含有可任选的载体，表面活性剂，分散剂和/或农用的辅助剂。
优选地，本发明含有1份-80份(wt)的噻吩磺隆和10份-50份(wt)的唑草酮，
更优选地，本发明含有15份(wt)的噻吩磺隆和40份(wt)的唑草酮。
更优选地，本发明它是由噻吩磺隆和唑草酮及相应的助剂配制成的乳油、可湿性粉剂、水分散剂、干悬浮剂等多种剂型。
噻吩磺隆为苗后选择性除草剂，可被植物的茎叶，根系吸收，并迅速传导。通过抑制侧链氨基酸亮氨酸的生物合成，而阻止细胞分裂，使敏感植物停止生长，在受药后1至3周内死亡。该药剂在土壤中能迅速被土壤生物分解，30天后对后茬作物无药害。适用作物：小麦、玉米、大豆等，防除对象：可以有效防除大部分一年生和多年生阔叶杂草，如：苘麻、野蒜、反枝苋、荠菜、藜、猪殃殃、马齿苋、猪毛菜、龙葵、牛繁缕、繁缕、王不留行、婆婆纳、地肤、本氏蓼、桃叶蓼等。
快灭灵其有效成分唑草酮carfentrazone-ethyl是一种原卟啉原氧化酶抑制剂，杂草吸收后细胞膜受到破坏，使杂草很快干枯死亡，在小麦田使用对多种阔叶草有显著防效。且杀草谱宽，是一种特色性强，具有广谱应用前景的除草剂。
本发明将两者复配，解决了小麦田除草剂的单一性。能有效防除小麦田的各种杂草。同时解决了小麦田除草剂速度慢的问题，加速了除草速度。还解决了小麦田除草剂对后茬作物的安全性，其残留期只有一个月。对于后茬种植花生、蔬菜的农民可以放心使用。
