Abstract
本发明提供了一种对于欲消除的植物诸如蓼属植物(Polygonum)、地肤(Kochia)、鼬瓣花(Galeopsis)、猪殃(Galium)、繁缕(Stelaria)、白芥(Sinapis)和野燕麦(Avena)等进行协同控制的方法,该方法包括对上述植物或其生长地施用一种协同有效量的芳氧基吡啶酰胺除草剂与一种或两种选择的附加除草化合物的组合。本发明还提供了协同增效的除草剂组合物,其含有芳氧基吡啶酰胺除草剂与一种或两种选择的附加除草化合物。
Description
芳氧基吡啶酰胺,正如在美国专利5,294,597中所描述的,表现出优异的除草活性,特别是对那些混杂于谷类作物中的宽叶草。然而,当芳氧基吡啶酰胺被用做唯一的活性成份时,在以作物安全上所要求的比例施用时,商业化农药应用中碰到的问题是它并不总是能够获得对整个广谱杂草物种的有效控制。这种在谱系控制中的不足常常可以通过使用已知可有效对抗相关草种的其它除草剂共同处理进行弥补。已经发现(美国专利5,674,807)有选择地联合使用芳氧基吡啶酰胺不仅能产生所期待的附加效果,还可显示出明显的协同效果(即,联合使用时表现出比单独使用单一成份时所可期待的活性更高)。这种协同效果使作物的安全有了更大余地。然而,该公开局限于芳氧基吡啶酰胺和经选择的已知化合物类别的双组分联用,并且所选择的已知化合物类别不包括咪唑啉酮,环己二酮、芳氧基苯氧基丙酸或吡啶羧酸类除草剂。此外,尽管公开了苯氧基乙酸类化合物,2,4-二氯苯氧基乙酸(2,4-D),它的酯和盐未被例举。
困此本发明的目的之一是提供一种具有协同作用的、有作物选择性的除草剂组合,其有广谱杂草控制功能。
本发明的另一目的是提供一种可用于对作物中杂草进行协同广谱控制的除草组合物。
尽管芳氧基吡啶酰胺化合物表现出优异的除草活性,但在单独应用并以作物的安全所要求的比例施用时,它们并不总可以获得理想的杂草谱系的控制。令人惊奇的是,现在发现,一种包括式I所示的芳氧基吡啶酰胺化合物:
其中:Z表示氧或硫原子;
R1表示氢或卤原子或烷基或卤代烷基;
R2表示氢或是烷基;
Q为0或1;
R3表示氢或烷基或链烯基;
每个X独立表示卤原子或视需要取代的烷基或烷氧基,优选卤代烷基,或链烯氧基,氰基,羧基,烷氧羰基,烷硫基羰基,烷基羰基,酰氨基,烷基酰胺基,硝基,烷硫基,卤代烷硫基,烯硫基,炔硫基,烷基亚磺酰基,烷基磺酰基,烷基肟基烷基或烯基肟基烷基;
n为0或1到5的任一整数;
每个y单独表示卤原子或烷基,硝基,氰基,卤代烷基,烷氧基或卤代烷氧基;且
m为0或1到5的任一整数;或其环境上可接受的盐,和选自2,4一二氯苯氧基乙酸(2,4-D)或其环境上可接受的酯或盐、咪唑啉酮、环己二酮、芳氧基苯氧基丙酸或吡啶羧酸除草剂作为第二除草剂的一种双组分组合表现出一种协同除草效果。此外,出乎意料的是,一种经选择的包括如式I所示的芳氧基吡啶酰胺,2,4-D或其环境上可接受的酯或盐,和选自咪唑啉酮、环己二酮、芳氧基苯氧基丙酸除草剂作为第三除草剂的三组分组合可产生显著的协同效果。有利的是本发明的双组分和三组分组合使得可以以较低的施用比例使用芳氧基吡啶酰胺,同时扩大了对杂草控制谱系。此外,本发明的协同除草方法和组合物使得能更有效地进行抗药性的管理。
本发明提供了一种对于欲消除的植物诸如蓼属植物(Polygonum)、地肤(Kochia)、鼬瓣花(Galeopsis)、猪殃(Galium)、繁缕(Stelaria)、白芥(Sinapis)、和野燕麦(Avena)等进行协同控制的方法,该方法包括对上述植物的生长地或叶或茎施用一种协同有效量的双组分除草剂组合,所述组合包括式I所示的芳氧基吡啶酰胺化合物和选自2,4-D式其环境上可接受的酯或盐、咪唑啉酮、环己二酮、芳氧基苯氧基丙酸、或吡啶羧酸除草剂的第二除草剂。本发明还提供了一种对于欲消除的植物进行协同控制的方法,该方法包括对所述植物的生长地施用一种协同有效量的三组分除草剂组合,所述组合包括式I所示的芳氧基吡啶酰胺,2,4-D或其环境上可接受的酯或盐和选自咪唑啉酮、环己二酮、芳氧基苯氧基丙酸酯除草剂的第三除草剂。
本发明还提供了一种协同增效的除草组合物,该组合物包括一种农业可接受载体和一种协同有效量的包含式I所示的芳氧基吡啶酰胺和选自2,4-D或其环境上可接受的酯或盐、咪唑啉酮、环己二酮、芳氧基苯氧基丙酸、或吡啶羧酸除草剂作为第二除草剂的双组分组合;或包括一种农业可接受载体和一种协同有效量的包含式I所示的芳氧基吡啶酰胺化合物、2,4-D或其环境上可接受的酯或盐、和选自咪唑啉酮、环己二酮、芳氧基苯氧基丙酸酯作为第三除草剂的三组分组合。
式I的芳氧基吡啶酰胺:
其中Z、R1、R2、R3、X、n、Y和m在上文中已定义,其制备方法已在美国专利5,294,597中描述。上述的芳氧基吡啶酰胺表现出优异的除草活性,特别是对谷物中的宽叶杂草。然而,当上述的芳氧基吡啶酰胺在商业化农业实践中作为唯一有效成份应用时,特别是联系到对作物物种的可靠选择性时,并不总可以取得对广谱杂草物种的有效控制。
令人惊奇的是,现在发现式I的芳氧基吡啶酰胺或其环境上可接受的盐和选自2,4一二氯苯氧基乙酸(2,4-D)或其环境上可接受的酯或盐、咪唑啉酮、环己二酮、芳氧基苯氧基丙酸或吡啶羧酸除草剂作为第二除草剂的一种双组分组合表现出一种对诸如蓼属植物(Polygonum)、地肤(Kochia)、鼬瓣花(Galeopsis)、猪殃(Galium)、繁缕(Stelaria)、白芥(Sinapis)、和野燕麦(Avena)等有害杂草的协同除草效果。此外,出乎意料的是,一种包括如式工所示的芳氧基吡啶酰胺,2,4-D或其环境上可接受的酯或盐,和选自咪唑啉酮、环己二酮、芳氧基苯氧基丙酸除草剂作为第三除草剂的三组分组合也可产生协同除草效果。也就是说,本发明的双组分或三组分组合提供了一种相互增强的作用,从而使得在应用中单个除草组分的施用比例降低但仍然可获得相同的除草效果,或是相应地,与单个除草组分在相同比例下单独使用的效果相比,除草组分的组合应用表现出一种更强的除草效果。
式I所示的芳氧基吡啶酰胺可以其环境可接受盐的形式存在。一般来说,合适的盐是那些其阳离子或阴离子不会影响活性成份的除草活性的阳离子的盐、或酸的加成盐。
特别地,合适的阳离子有碱金属离子,优选锂、钠和钾;碱土金属离子,优选钙和镁;和过渡金属离子,优选锰,铜,锌和铁;以及铵,在此,如有必要,其1-4个氢原子可被C1-C4烷基、羟基-C1-C4-烷基,C1-C4-烷氧基-C1-C4-烷基,羟基-C1-C4-烷氧基-C1-C4-烷基,苯基或苄基取代,优选铵、二甲基铵、二异丙基铵、田甲基铵、四丁基铵、2-(2-羟基乙-1-氧基)乙-1-基铵,二(2-羟基乙-1-基)铵,三甲基苄基铵;以及离子、锍离子,优选三(C1-C4烷基)锍,和氧化锍离子,优选三-(C1-C4-烷基)氧化锍。
合适的酸加成盐的阴离子主要是氯、溴、氟、硫酸氢根、硫酸根、磷酸二氢根、磷酸氢根、硝酸根、碳酸氢根、碳酸根、六氟代硅酸根,六氟代磷酸根、苯甲酸根以及C1-C4烷酸阴离子,特别是甲酸、乙酸、丙酸和丁酸根。
在说明书和权利要求中,术语2,4-D也可以其环境可接受的酯或盐的形式存在。一般来说,合适的盐是指那些不会影响活性成份的除草活性的那些阳离子的盐。
特别地,合适的阳离子是碱金属离子,优选的是锂、钠、钾,碱土金属离子,优选的是钙和镁,以及过渡金属离子,优选的是锰、铜、锌和铁,以及铵,在此,如有必要,其1到4个氢原子可被以下基团取代:C1-C4烷基、羟基-C1-C4-烷基、C1-C4-烷氧基-C1-C4-烷基、羟基-C1-C4-烷氧基-C1-C4-烷基,苯基或苄基,特别是铵、二甲铵、二异丙基铵、(2-羟基-乙-1-基)铵、二-(2-羟基-乙-1-基)铵或三-(2-羟基-乙-1-基)铵。特别合适的阳离子是钠、二甲铵、二-(2-羟基-乙-1-基)铵和三(2-羟基-乙-1-基)铵。

为了更好地理解本发明,下面将给出实施例。这些例子仅仅是用来说明,不可被理解为限制本发明的范围或是以任何方式给出了本发明的原则。
在下面的实例中,双组分组合的协同作用是由Colby方法确定的(S.R.Colby,杂草1967(15),20),即该组合所期望(或预测的)响应是通过对组合中单个组分在单独应用时被观测到的响应的乘积除以100再从每个组分在单独应用时被观测到的响应总和中扣除该值。这种组合的协同作用可通过比较该联合被观测到的响应与计算出的预期(或预测的)的响应来确定。如果该组合被观测到的响应比预期值(预测值)大,那么该组合即是增效的。
下面先给出的数学图示,其中双组分组合C2是由组分X加组分Y组成,Obs.表示观测到的组合C2响应。
增效作用=Obs.>Exp
相似的方法可用于三组分组合C3,C3是由组分X加组分Y加组分Z组成。Obs.表示观测到的组合C3响应。
增效作用=obs.>Exp.
在下面的例子中,作物的耐受率通过生长季节被周期性地采集。第一个比率是在防治后的第一到第二个星期之后,最后一个比率是在收获之前采集的。在所有下面描述的防治中,作物的耐受性在商业上都是可接受的,即三种作物中的每一种均为≤20%的伤害。没有一种防治会对大麦、硬粒麦、红皮硬粒春小麦产生商业上不可接受的伤害。
实施例1
评价picolinafen和2.4-二氯苯氧基乙酸组合的除草活性
草和宽叶杂草在五月中上旬按作物的播种方向播种,在杂草播种后再种植作物。行距为18cm,种子用Roger’s 1.8米宽的条播机播种至5cm的深度。
所有的试验均采用标准杂草学步骤。使用Roger’s以二氧化碳为动力的喷雾器。试验方案是经修改的随机完整块田试验,做四个重复实验。所有试验都是在杂草和作物出芽后进行的。
试验溶液是将足够量的参试化合物的水溶液和/或分散体在罐中进行混合制备的。
在生长季节对试验田定期检查并评估对杂草的百分控制及对作物的伤害。表中列出的数据是该重复试验的平均数据。用Colly分析法确定组合防治与单独使用时的生物效果的比较。数据见表I。
从表I的数据中可以看出,picolinafen加2.4-D的联用,与picolinafen单独使用或2.4-D单独使用时可以预见的杂草控制效果相比,产生了明显高的杂草控制效果。表IPicolinafen加2.4-D组合的除草活性的评价

从表VIII的数据中可以看出,picolinafen加高噁唑禾草灵(Fenoxaprop-p-ethyl)以及2,4-D的联合应用,与picolinafen单独使用或高噁唑禾草灵(Fenoxaprop-p-ethyl)单独使用或2,4-D单独使用时可以预见的杂草控制效果相比,产生了明显高的杂草控制效果。
