Description

一种除草剂组合物
技术领域
本发明属于农药技术领域,尤其涉及一种除草剂组合物。
背景技术
世界各地分布着大量的杂草,其中,多数会对农业生产造成危害,使作物产量大幅度降低,成为影响农业生产的重要因素之一。但是,化学除草剂的过量使用,以及单一除草剂或作用机理相同的除草剂的长期使用,会对环境造成严重的负面影响。同时,会加速杂草耐药性的产生,使杂草的群体结构发生变化,影响除草效率。据估计,杂草的多重抗性与除草剂作用模式之间的矛盾日益加剧,对杂草防除构成了巨大的威胁。
目前,使用除草剂仍然被认为是最快捷、高效的杂草防除方法。但除草剂的发展却面临严峻的挑战,要保持长期可持续的发展,就必须与环境保护密切结合。因此,研发或通过复混得到具有广谱、高效、低污染的新型除草剂是杂草防除领域重要的研究方向。
发明内容
本发明提供了一种除草剂组合物,通过多元复配的除草剂组合物防治农田杂草,解决目前单一类除草剂杀草谱小,受农作物和杂草种类限制,除草效果差的难题。
本发明采用的技术方案如下:
一种除草剂组合物,包括活性成分精恶唑禾草灵、甲草胺、噻吩磺隆和2,4-D,所述精恶唑禾草灵、甲草胺、噻吩磺隆和2,4-D的质量比为(5~10):(15~30):(8~20):(2~9)。
优选的,所述精恶唑禾草灵、甲草胺、噻吩磺隆和2,4-D的质量比为(7~9):(18~25):(10~15):(6~8)。
具体的,所述活性成分精恶唑禾草灵、甲草胺、噻吩磺隆和2,4-D的含量占所述除草剂组合的10%~85%。
优选的,所述活性成分精恶唑禾草灵、甲草胺、噻吩磺隆和2,4-D的含量占所述除草剂组合的20%~70%。
上述任意一项除草剂组合物,其还包括辅助剂,包括消泡剂、洗涤剂和溶剂。
本发明中的精噁唑禾草灵:分子式:C18H16ClNO5,化学名称:(R)-2-[4(6-氯-1,3-苯并噁唑-2-氧基)苯氧基]丙酸乙酯,英文名称:fenoxaprop-p-ethyl。常用于大豆、花生、棉花、水稻田等阔叶作物防除禾本科杂草。属杂环氧基苯氧基丙酸类除草剂,主要是通过抑制脂肪酸合成的关键酶一乙酰辅酶A羧化酶,从而抑制了脂肪酸的合成。
本发明中的甲草胺是一种选择性芽前除草剂。化学名称:2-氯-N-(2,6-二乙基苯基)-N-(甲氧甲基)乙酰胺。用作芽前和芽后早期除草剂,可防除棉花、玉米、油菜、花生、大豆和甘蔗中一年生禾本科杂草和许多阔叶杂草;选择性旱地芽前除草剂。植物幼芽吸收药剂后,抑制蛋白酶的活力,阻碍蛋白质合成,致使杂草死亡。
本发明中的噻磺隆属内吸传导型苗后选择性除草剂,是支链氨基酸合成抑制剂,能抑制缬氨酸、亮氨酸、异亮氨酸的生物合成,阻止细胞分裂,使敏感作物停止生长。主要用于防除禾谷类作物小麦、大麦、燕麦、玉米田间的阔叶杂草。
本发明中的2,4-D在500ppm以上高浓度时用于茎叶处理,可在麦、稻、玉米、甘蔗等作物田中防除藜、苋等阔叶杂草及萌芽期禾本科杂草。
本发明的有益效果:
1)提供一种具有四种活性成分的除草剂组合物,该混配可以提高杂草防除效果及反应速度,并能提高对作物的安全性,杀草谱广,活性高,适合各种田间阔叶杂草和一年生杂草比较多的地区;
2)除草谱广,对水稻、玉米、小麦、高粱、大豆和棉花等均有一定作用,对作物和人畜相对安全;
3)由于组合物中的各有效成分的作用机制各不相同,降低了杂草产生抗性的风险。
