Abstract
本发明公开了一种用于大豆的除草剂，解决了现有除草剂效果不佳的问题，其特征在于由氟磺胺草醚、乙草胺、精喹禾灵或者氟吡甲禾灵和水混合组成。本发明可全面防治大豆田的一年生阔叶杂草和禾本科杂草，特别是对大豆田常见的菟丝子草效果显著，杀杂草不反弹，一次施药基本可铲除杂草危害，而且不影响大豆的产量，省工、省时、省钱。
Description
技术领域
本发明涉及一种复配除草剂，更确切地说涉及一种用于大豆田防除杂草的除草剂。
背景技术
目前广泛用于大豆田的除草剂往往是一种单剂，杀杂草谱比较单一，不能有效控制大豆田整个生长期的草害，安全性比较差。特别是大豆田里的菟丝子草，为一年生寄生草本植物，丝状，附着在土粒上，另一端形成丝状的菟丝，在空中旋转，碰到豆棵就缠绕其上，在接触处形成吸根，吸取豆棵的养分和水分，而且茎不断分枝伸长形成吸根，再向四周不断扩大蔓延，严重时将整株豆棵布满菟丝子，使豆棵生长不良，甚至引起全株豆棵死亡，有时不得不连豆棵一起拔掉。
发明内容
本发明的目的在于克服现有技术的不足提供一种用于大豆的除草剂，制备简单、除草效果明显，不留草根，具有广谱、高效的优点，除菟丝子草显著。
本发明的特征在于由药液原剂和水组成，按重量份数所述的药液原剂为20-50份，水为1000-1500份；所述的药液原剂按重量份数由A、B组分组成：所述的A组分由25％的氟磺胺草醚10-30份、50％乙草胺10-30份组成，所述的B组分为精喹禾灵15-30份，或者为10.8％氟吡甲禾灵10-30份，或者由精喹禾灵8-15份和10.8％氟吡甲禾灵5-15份组成；所述的精喹禾灵含量为8.8％或者10.8％。
由上述技术方案可知，本发明把几种单一除草剂复配在大豆苗后使用，可全面防治大豆田的一年生阔叶杂草和禾本科杂草，如麦苗子、地扁草、铁苋菜、毛谷草、马齿苋、野苋菜、香包子草、狗尾草等，特别是对大豆田常见的菟丝子草效果显著，杀杂草不反弹，一次施药基本可铲除杂草危害，而且不影响大豆的产量，省工、省时、省钱。
具体实施方式
实施例1
取25％氟磺胺草醚18g、50％乙草胺14g、8.8％精喹禾灵20g混合，搅拌均匀得药液原剂；把药液原剂和水20000g混合均匀制成水溶性制剂。
施药方法：在大豆播种之日起10天-20天，在喷雾器内先加少量的水，放入上述药液原剂，然后再加入余量的水，搅拌均匀即可喷洒在豆田里和豆苗上。
除草效果：一年生草本植物如大豆田常见的地扁草、麦苗子、铁苋菜、毛谷草、马齿苋、野苋菜、香包子草、狗尾草等杂草，特别是菟丝子草直到收割大豆时都没有，达到了预防效果。有时由于喷雾不够彻底、全面，局部出现杂草时，或者有个别豆棵上缠绕菟丝子草时，可用上述制剂直接喷雾在杂草或豆棵上，一般2-4天菟丝子草等杂草即枯萎死亡。
