Description

一种小麦田除草剂
技术领域
本发明涉及一种小麦田除草剂。
背景技术
随着社会快速的发展，科学技术进一步的提高。农民对除草剂的不断的认识、不断地使用。目前小麦田除草剂的种类也在发生着变化，小麦田次要的杂草已经演变为主要的杂草。如泽漆(毛毛眼)、猪殃殃已经是小麦田主要的杂草，并且很难防治。同时随着用药量的增加，使杂草的抗药性在不断的加强。现有的苯磺隆+氯氟吡氧乙酸(酯)，虽然对泽漆、猪殃殃有特效，但是它也有着自己的局限性。首先是用药期短在小麦的2叶期至拔节前用药。其次对部分后茬作物不安全如：后茬种植花生的安全间隔期最少是四个月。
发明内容
本发明需要解决的问题就在于克服现有技术的缺陷，提供一种小麦田除草剂，它对小麦田常见的杂草都能有效的防除并且对于比较难以防治的杂草泽漆、猪殃殃有特效。
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，它含有1份-99份(wt)的噻吩磺隆和1份-99份(wt)的氯氟吡氧乙酸(酯)，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-30份(wt)的噻吩磺隆和10份-30份(wt)的氯氟吡氧乙酸(酯)。
更优选地，本发明含有15份(wt)的噻吩磺隆和20份(wt)的氯氟吡氧乙酸(酯)。
更优选地，本发明是由噻吩磺隆和氯氟吡氧乙酸(酯)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。
使它隆除草剂是美国陶氏益农专为小麦研制生产的一种高效阔叶杂草除草剂，其有效成分为氯氟吡氧乙酸(酯)，特效防除猪殃殃、繁缕、播娘蒿、泽漆等。
本发明将两者复配，对小麦田常见的杂草都能有效的防除并且对于比较难以防治的杂草泽漆、猪殃殃有特效。对于后茬种植花生、蔬菜的作物比较安全，其安全间隔期只需要1个月。
具体实施方式
