Description
技术领域
本发明涉及农药制备领域，具体一种含有高效氟吡甲禾灵的除草组合物。
背景技术
高效氟吡甲禾灵属芳氧苯氧丙酸类选择内吸传导型除草剂，又名高效盖草能，是一种脂肪酸合成抑制剂，是新一代氟代杂环高效除草剂，该药剂由叶片、茎干和根系吸收，在植物体内抑制脂肪酸的生物合成，使细胞生长、分裂停止，使细胞膜等含脂肪的结构被破坏而导致杂草死亡。草甘膦化学是一种有机膦类除草剂，主要通过阻碍芳香氨基酸的生物合成，和抑制其他植物酶和动物酶的活性的途径来达到除草的目的。精喹禾灵，属于苯氧羧酸类除草剂，通过杂草茎叶吸收，在植物体内向上和向下双向传导，积累在顶端及居间分生，抑制细胞脂肪酸合成，使杂草坏死。精喹禾灵是一种高度选择性的新型旱田茎叶处理剂，在禾本科杂草和双子叶作物间有高度的选择性，对阔叶作物田的禾本科杂草有很好的防效。
目前单独使用高效氟吡甲禾灵不能完全有效地控制杂草，且存在亩使用量高、杂草抗药性日趋严重的趋势。针对现有技术的缺点，提供一种除草效果好，尤其对多年生禾本科杂草效果优异、持效期长、安全性能高、增产作用显著、施药方便、毒性低的复配除草剂成为迫不及待的市场需求。
合理的化学除草剂复配或混配具有扩大除草谱，提高防治效果、延长施药适期、减少用药量、降低药害、减少残留、延缓抗药性的发生与发展等积极特点，除草剂复配或混配是解决上述问题的最为有效的方法之一。我们在室内筛选和田间试验的基础上，筛选出草甘膦、精喹禾灵与高效氟吡甲禾灵复配，具有明显的增效作用。且关于高效氟吡甲禾灵、草甘膦和精喹禾灵复配的除草组合物及应用目前尚无人报道过。
发明内容
基于背景技术存在的技术问题，本发明提出了一种含有高效氟吡甲禾灵的除草组合物
一种含有高效氟吡甲禾灵的除草组合物，其特征在于：该除草组合物以高效氟吡甲禾灵、草甘膦与精喹禾灵为主要有效成分，其中高效氟吡甲禾灵的质量百分比为5～30％，草甘膦的质量百分比为5～20％，精喹禾灵的质量百分比为 5～20％。
优选的，所述的除草组合物还包括乳化剂、分散剂、稳定剂、增稠剂、植物油和去离子水。
优选的，乳化剂为十二烷基苯磺酸钙、烷基酚聚氧乙烯醚、蓖麻油环氧乙烷中的一种或多种；所述的分散剂为烷基萘磺酸钠、木质磺酸盐中的一种或多种；所述的稳定剂为环氧氯丙烷、丁基羟基茴香醚中的一种或多种；所述的增稠剂为硅酸铝镁、白炭黑中的一种或多种；所述的植物油为环氧大豆油、玉米油中的一种或多种。
优选的，乳化剂的质量百分比为5～20％；所述的分散剂的质量百分比为 0.1～20％；所述的稳定剂的质量百分比为0.1～20％；所述的增稠剂的质量百分比 1～25％；所述的植物油的质量百分比为0.1～20％；所述的去离子水的质量百分比为5～50％。
优选的，除草组合物剂型为可分散油悬浮剂。
优选的，除草组合物适用于植物播种后除草或苗生长中除草。
优选的，除草组合物用于小麦、玉米、大麦和燕麦等作物中杂草的去除。
优选的，除草组合物可去除阔叶杂草和禾本科杂草。
与已有技术相比，本发明的有益效果体现在：
(1)协同增效、除草活性高高效氟吡甲禾灵、草甘膦与精喹禾灵的除草组合物通过作用植物不同的部位，通过不同途径杀死杂草，三种配合使用，协同增效作用，可以极大地提高除草剂的杀草活性；
(2)降低用量、提高防效通过实验试验证明，三者混配有显著的增效作用，能扩大杀草谱，降低亩用量，提高防效，且对作物安全；
具体实施方式:
下面将对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
