  • HPPD p-hydroxyphenylpyruvate dioxygenase
  • HPPD inhibitory herbicides entered the market later than AHAS-, PPO-, and ACCase-inhibitory herbicides. Although they started late, they did not prevent the "star molecules" from occupying the market quickly. It is a trione herbicide-mesotrione (also known as mesotrione) developed by Syngenta. It has occupied the top five herbicide sales for many years. In corn fields with frequent weed resistance, mesotrione has gradually replaced other types of herbicides as the most widely used and effective corn field herbicides.
  • mesotrione still has some inherent shortcomings.For example, it is less safe for other bulk crops such as wheat, rice, soybeans and rapeseed. Hair weeds, foxtail and golden foxtail, etc.) have poor control effects. There are also reports in the literature that weeds tend to turn green after using mesotrione. Recently, ciclopirox, created by Qingyuan Nongguan, became the first HPPD herbicide in wheat field in China (as disclosed in CN105218449A), which can effectively control resistance and multi-resistance. Gramineous weeds and some broad-leaved weeds provide more choices for herbicide use in wheat fields. However, ciclopirox is not ideal for controlling weeds such as brome, wild oats, and knotty wheat, which are harmful to wheat growth. In addition, the specific structure of ciclopirox is as follows:
  • HPPD herbicides there are still some limitations of the nearly 20 commercial HPPD herbicides that have been developed so far. Most varieties are cornfield herbicides. There is no practical agricultural production in China that can be used for wheat, rice, sorghum, HPPD herbicides for millet, peanut, soybean and other crops.

Description

含喹唑啉二酮片段的化合物及其制备方法和应用以及一种除草剂 技术领域
本发明涉及农药除草剂领域,具体涉及一种含喹唑啉二酮片段的化合物及其制备方法和应用,以及一种含有该含喹唑啉二酮片段的化合物的除草剂。
背景技术
在近年来研究和实际田间应用中,发现对羟苯基丙酮酸双加氧酶(HPPD)抑制类除草剂具有毒副作用低、环境友好等特点,更为重要的是,相比于AHAS,ACCase,PSII类除草剂极为严重且呈指数倍增加的杂草抗性问题,针对HPPD抑制类除草剂的抗性报道却鲜有耳闻,其抗性问题是目前所有靶向除草剂中严重程度最低且发展最为缓慢的除草剂之一,并且与其他类型除草剂之间没有交互抗性。由此可以看出,HPPD类除草剂具有全新的除草作用机制,可以作为治理抗性杂草的有力工具。
截止目前,靶向HPPD所开发成功的除草剂多达数十种,以结构分类大致可以归为三大类:1、以硝磺草酮(Mesotrione)为代表的三酮类;2、以苯唑草酮(Topramezone)为代表的吡唑类;3、以异噁氯草酮(Isoxachlortole)为代表的异噁唑类。
经过农药市场销售额调查,HPPD抑制类除草剂进入市场时间较AHAS-、PPO-以及ACCase-抑制类除草剂相比起步虽晚,但不妨碍其中的“明星分子”对市场的迅速占领,特别是由先正达公司研发的三酮类除草剂-硝磺草酮(又名:甲基磺草酮),连续多年占领除草剂销售额前五。在抗性杂草多发的玉米田中,硝磺草酮已经逐渐代替了其他类型的除草剂成为使用最广和最为有效的玉米田除草剂。
然而,硝磺草酮仍然存在着一些自身不足,例如其对其它的一些大宗作物如小麦、水稻、大豆和油菜等安全性较差,同时硝磺草酮对多种禾本科杂草(如普发性杂草狗尾草和金狗尾草等)防效较差,也有文献报道使用硝磺草酮后杂草易出现返青现象等。最近由清原农冠公司创制的环吡氟草酮成为了我国首个麦田HPPD除草剂(如CN105218449A中所公开),其可以有效防除抗性及多抗性的看麦娘、日本看麦娘等禾本科杂草及部分阔叶杂草,为小麦田的除草剂使用提供了更多选择。然而,环吡氟草酮对雀麦、野燕麦、节节麦等多种危害小麦生长的禾本科杂草防效却并不理想。另外,环吡氟草酮的具体结构如下:

然而,目前已开发的近20种商品化HPPD除草剂仍然存在着一定的局限性,绝大多数品种都是属于玉米田除草剂,我国农业生产实际中还没有可以用于小麦、水稻、高粱、谷子、花生、大豆等作物的HPPD除草剂。
进一步地,鉴于我国农业生产实际中还没有能够有效防治严重危害小麦生长的雀麦、野燕麦、节节麦等禾本科杂草的HPPD除草剂;以及针对经济作物花生,目前仍然缺乏可使用的HPPD抑制型除草剂用于防治花生田例如稗草、马唐、狗尾草等禾本科杂草。
因此,为满足我国农业生产中的现实需求,创制出可以防除多种作物(特别是小麦和花生)田禾本科杂草的新型超高效HPPD除草剂具有十分重要的意义。
发明内容
本发明的目的之一是为了克服现有技术存在的上述缺陷,提供一种能够用于防除禾本科杂草和部分阔叶杂草的广谱性HPPD除草剂。
本发明的目的之二是为了提供一种对稗草、狗尾草、马唐、雀麦、野燕麦、节节麦等多种难防治禾本科杂草具有良好防效的含喹唑啉二酮片段的化合物。
为了实现上述目的,本发明的第一方面提供一种含喹唑啉二酮片段的化合物或其农业化学上可接受的盐、水合物、溶剂化物,或其对映异构体、光学活性形式的衍生物,该化合物具有式(I)所示的结构,
