本发明属于农药技术领域,具体涉及一种苯基吡唑啉衍生物或其盐、组合物,并涉及这些化合物或其盐、组合物作为除草剂的用途。
背景技术
随着农业生产水平的提高,人们越来越认识到除草剂、杀虫剂、杀菌剂等药物的重要作用,目前已普遍采用化学除草、杀虫或杀菌,如玉米、大豆、棉花、小麦和水稻等作物的种植过程中常常使用除草剂、杀虫剂、杀菌剂等药物。尽管目前农业生产过程中使用的除草剂、杀虫剂、杀菌剂种类繁多,但由于植物病虫草害的抗性问题、药物的效率及使用成本等问题的不断涌现,依然需要针对杀虫剂、杀菌剂、除草剂等药物的高效性、成本、残留等问题进行持续地研究。其中,对于具有苯基吡唑啉结构的生物活性化合物已经在公开号为CN1292791A、CN1355806A的专利中有描述,但其植物出苗后的除草活性可能不甚令人满意,且均不能同时兼具杀菌、除草的活性。
发明内容
为解决现有技术中存在的上述问题,本发明提供了一种取代的苯基吡唑啉衍生物或其盐、组合物及其用途。申请人通过对苯基吡唑啉衍生物类化合物的大量研究,以苯基吡唑啉衍生物的结构为基础引入了取代的吡唑基团,开发得到了一类可用作除草剂和/或杀菌剂,具有非常突出的生物活性和作物安全性。
本发明为实现上述目的采用的技术方案是:一种苯基吡唑啉衍生物或其盐,其结构式如下:

对于许多一年生的单子叶和双子叶不想要的植物,本发明的式I化合物具有突出的除草活性。本发明的活性物质也对于多年生杂草有效,这些杂草从根茎、根状茎、或其它的多年生的器官上生长出来。至于本发明的活性物质的使用时机,可以是在播种前、萌发前或萌发后。特别提及本发明化合物可以控制的单子叶和双子叶杂草群的代表例,本发明的活性物质能起到有效作用的杂草物种代表例包括单子叶植物:一年生燕麦属、黑麦草属、看麦娘属、稗、马唐属、狗尾草属和莎草属,和多年生的冰草属、狗牙根属、白茅属和高粱属、以及多年生的莎草属。
关于双子叶杂草物种,其作用可以扩展到的物种例如一年生的猪殃殃属、堇菜属、婆婆纳属、野芝麻属、繁缕属、苋属、白芥属、番薯属、黄花稔属、母菊属和苘麻属,和多年生杂草旋花属、蓟属、酸模属和艾属。本发明活性物质在水稻播种这种特定条件下依然能有效控制不想要的植物,例如稗、慈姑属、泽泻属、荸荠属、蔗草和莎草属。如果将本发明化合物在萌芽前施用于土壤表面,可以在杂草长出前完全预防杂草的秧苗,或在杂草长出子叶时就停止生长,最后在三到四星期之后完全死亡。虽然本 发明化合物对于单子叶和双子叶的杂草具有优良的除草活性,但对于重要的经济类作物植物,例如小麦、大麦、黑麦、稻子、玉米、甜菜、棉花和大豆却没有损害,或者是损害非常微小。因此,本发明化合物非常适于有选择地控制在农用作物或观赏植物中的无用植物。另外本发明化合物可以明显调节作物植物的生长。通过调节参与植物代谢,使用这些化合物定向控制植物的组分和促进收获,例如使植物干化和矮化生长。而且它们也适于调节和抑制不希望的植物生长,而不破坏作物的生长。抑制植物的生长在许多单子叶植物和双子叶植物作物中起着非常重要的作用,因为这样可以减少或完全预防倒伏。
可以使用一般的制剂来应用本发明的化合物,可使用可湿性粉剂、可溶性粉剂、乳油、水乳剂、悬浮剂、可分散油悬浮剂、粉剂、微囊悬浮剂、水分散粒剂、水溶性粒剂等。这样本发明也提供了包括式I化合物的除草剂组合物。根据通常的生物学和/或化学的物理参数,可以用多种方式配制式I化合物。适合的制剂选择实例为:可湿性粉剂(WP)、可湿性液剂(SL)、可溶性粉剂(SP)、可分散液剂(DC)、水剂(AS)、微乳剂(ME)、乳油(EC)、水乳剂(EW)、可喷洒溶液、悬浮剂(SC)、可分散油悬浮剂(OD)、粉剂(DP)、微囊悬浮剂(CS)、水分散粒剂(WG)、水溶性粒剂(SG)、大粒剂(GG)、用于撒播和土壤施药的颗粒剂(GR)、气雾剂(AE)、超低容量剂(ULV)和蜡制品。必要的制剂助剂,例如惰性物质、表面活性剂、溶剂及其它添加剂。

实施例8
杀菌生物活性评价:
称取一定质量化合物样品,溶解于丙酮中,配制成母液备用。试验时,将化合物样品和对照药剂(95%氟吡菌胺TC、10%氟噻唑吡乙酮OD、95%唑啉草酯TC,均为市售)用0.1%吐温80的水配制成系列浓度梯度药液(供试化合物及对照药剂的药剂浓度:400mg/L),用于活体筛选。选择生长整齐一致的1叶1心期盆栽黄瓜幼苗(新泰密刺)作为黄瓜霜霉病(Pseudoperonospora cubensis)的试验寄主植物。喷雾器类型为生测喷雾塔,每处理喷30ml药液,自然晾干。24h后接种病原菌,设空白对照。采用接种器将黄瓜霜霉病菌孢子悬浮液喷雾于黄瓜苗上,用黑色塑料袋将接种好的黄瓜苗套袋保湿12h后,摘袋,温室培养(22℃,RH=50,无光照)。4d-10d后待幼苗长至4-6片真叶期时调查化合物的杀菌活性。结果调查参照美国植病学会编写的《A Manual of Assessment Keys for Plant Diseases》,用100~0来表示,以“100”级代表无病和“0”级代表最严重的发病程度。
