本发明的化合物可以用作出苗前和出苗后除草剂。一般来说,它们只需较低剂量来控制出苗前杂草。出苗前除草剂通常在播种前,播种中或播种后,但在作物长出之前施用于土壤上。出苗后除草剂是在作物长出后和其生长过程中施用。具体的物质一般显示出对一些重要农业经济作物具体选择性,如玉米,棉花,水稻,大豆,甜菜,向日葵,花生和小麦。
在某些条件下,可将本发明的化合物在作物栽培之前掺加到所说的土壤或其它生长介质中。这种掺加可以通过任何方便的方式,包括与所说的土壤混合,将所说的化合物施用于土壤表面,然后透入土壤至所需浓度,或采用液体载体的方法。
本发明的2-芳基嘧啶可以施用于各种地方,如所说的土壤或叶片上。为此目的,这些化合物可以以制备技术的或纯的形式使用,例如,溶液或组合物的形式。通常将所说的化合物溶解于载体中或配制成组合物作为除草剂,以使其适用于后续的散布。例如,可以将这些化学剂配合成可湿性粉末,乳油,粉末,颗粒状组合物,烟雾剂或可流动的乳油。在这种组合物中,所说的化合物被液体或固体所分散,需要时,可以加入适当的表面活性剂。
在通常情况下,特别是在叶面喷洒组合物的情况下,希望根据农业实践包括一些助剂,例如,润湿剂,扩展剂,分散剂,粘着剂,粘附剂等。本领域通常使用的这些助剂公开于the John W.McCutcheon,Inc.publication“Detergents and Emulsifiers,Annual.”Allured Publishing Company,Ridgewood,New Jersey,U.S.A.
这种2-芳基嘧啶可以通过常用的方法以除草喷雾剂的形式施用所说的常用方法例如,传统的高加仑水力喷雾,低加仑喷雾,气喷雾飞机喷雾和撒粉。所采用的稀释度和施用量将取决于所用设备的种类所用的施用方法和所要控制的杂草,但是,优选的有效量一般为约0.01-10磅有效成分/英亩。
当进行土壤处理时,所说的化学物质可以掺加到土壤中或施用其表面上,通常用量为约0.01-10磅/英亩。当进行叶面喷洒时所说的毒药剂通常施用在生长着的植物上,用量为约0.01-10磅/英亩。
本发明的2-芳基嘧啶还可以在施用前与肥料相混合。在一种固体肥料组合物类型中,可以使用所说的芳基嘧啶,肥料或肥料组分,如硫酸铵,硝酸铵或磷酸铵的颗粒,可以用一种或多种化合物来涂覆。所说的固体化合物或固体肥料也可以在混合设备中混合,或者它们可以与肥料结合成粒状组合物。适用于作物和待处理的杂草的任何相对比例的肥料都可以使用。所说的2-芳基嘧啶通常为所说的肥料组合物的约5%-25%。这些组合物提供了肥料,该肥料可以促进所需作物迅速生长,同时控制不需要的杂草的生长。
对于某些应用,在本发明的除草剂中可以加入一种或多种其它的除草剂。由此产生附加优点和效果。当使用除草剂混合物时,所使用的相对比例将取决于对待处理的植物混合物中的化合物的相对药效。可以与本发明的除草剂相结合的其它除草剂的例子包括:
