Description
技术领域
本发明属于除草剂技术领域,涉及除草剂在作物中选择性防治禾本科杂草和阔叶杂草的用途。本发明具体涉及一种嘧啶水杨酸肟酯类化合物的制备方法及其作为除草剂的应用。
背景技术
乙酰乳酸合成酶(ALS)抑制剂是上世纪80年代开发兴起的一种新型除草剂,即通过阻止氨基酸的生物合成而达到防除杂草的作用。其具有广谱、高效、低毒等特点,现已被广泛应用于田间的杂草防治。近年来,基于乙酰乳酸合成酶为靶标的抑制剂被大量开发。从化学结构分此类除草剂主要有磺酰脲类、咪唑啉酮类、嘧啶并三唑类、嘧啶水杨酸类等。与其它几种ALS抑制剂相比,嘧啶水杨酸类结构变化更为灵活。
嘧啶水杨酸类除草剂为日本组合化学公司首先开发的新型除草剂。该药剂对稻田中广范围的禾本科杂草和阔叶杂草有显著效果。其最大的商业潜力是能选择性地防除稗草,且用量极低,应用范围广,从而越来越引起人们的重视。嘧啶水杨酸类除草剂的商品化品种主要有:双草醚,嘧草醚,嘧啶肟草醚,嘧硫草醚和环酯草醚。其中,嘧硫草醚是该类除草剂第一个商品化品种,也是棉花田专用除草剂,对棉花高度安全。它可以防除一年生和多年生禾本科杂草和大多数阔叶杂草。对难除杂草如各种牵牛、苍耳、苘麻、刺黄花禾念,田普、阿拉伯高粱等都有很好的防除效果。
由于ALS抑制剂的作用靶标单一,连续使用易诱发杂草产生抗药性,随着除草剂嘧硫草醚的广泛使用,杂草抗药性问题越来越突出,针对这一问题,发现并开发使用剂量低、活性更高的新型嘧啶水杨酸类衍生物具有重要意义,可以为除草剂提供更多的选择。

本发明的嘧啶水杨酸类化合物具有良好的除草活性,可用作除草剂的有效活性成分,制备各种农药剂型,例如可湿性粉末,乳剂,水分散颗粒剂,片剂,颗粒剂等。
使用本发明制备的除草剂进行除草活性测试,结果如下:
1.测试药剂及配制
用万分之一分析天平称取20mg的嘧啶水杨酸类化合物原药,用丙酮(或DMF或DMSO)溶解,用0.1%吐温80水溶液稀释成浓度为45g a.i/hm2。
2.实验设计:
3.试验方法
试验土壤定量装至盆钵的4/5处,采用盆钵底部渗灌方式,使土壤湿润。将测试杂草种子分别播种与土壤表面,于温室中培养。待禾本科杂草长到3~4叶期,阔叶杂草4~6叶期时,使用茎叶喷雾法处理。施药后第21天取地上部分称量鲜重,按照公式计算鲜重抑制率。
鲜重抑制率(%)=(对照鲜重-处理鲜重)/对照鲜重×100%
嘧草硫醚作为阳性对照。通过对目标化合物的除草活性普筛;剂量参考嘧硫草醚在棉花田的施用剂量,为45g a.i/hm2时,茎叶喷雾处理,结果见表1。
表1.嘧啶水杨酸类化合物的室内除草活性
从上表1可以观察到,45g a.i./hm2下,嘧啶水杨酸类化合物具有良好的抑制稗草、牛筋草、反枝苋、马齿苋、藜等杂草的活性,对狗尾草抑制不明显。其对阔叶科杂草活性普遍优于禾本科杂草,J、K、L和M对阔叶科杂草的抑制率高于90%,均优于嘧硫草醚。
本发明的嘧啶水杨酸类除草剂化合物均为新型、未报导的化合物,并测定了其对稗草、牛筋草、反枝苋、马齿苋、藜等杂草的抑制活性,其中含氟、硝基以及2,4-二甲氧基的化合物对杂草的抑制活性较好,抑制活性均达到85%以上,甚至100%(除了狗尾草),且均高于商品化除草剂嘧硫草醚,显示出优秀的除草效能。
4.结论
本发明对嘧啶水杨酸类化合物进行了广泛的研究,目的在于研究一种具有高效、广谱、安全的化合物,结果发现,引入官能团氟、硝基、间三氟甲基均对供试杂草有较好的防治效果,可作为除草剂的候选化合物。
以上所述仅是本发明的优选实验方式,应当指出,对于本技术领域的普通技术人员,在不脱离本发明的前提下,还可以做出若干改进和补充,这些改进和补充也应视为本发明的保护范围。
