Abstract
一种长季节防治不期望植物的方法,所述方法包括一次施用含有2-(取代的苯甲酰基)-1,3-环己二酮或其金属螯合物、草甘膦或其盐和乙酰胺的除草组合物。
Description
本发明涉及一次处理对不期望植物提供长季节防治的方法。
保护作物免受杂草和其它抑制作物生长的植物的侵害是农业中经常面临的问题。为了帮助解决该问题,合成化学领域的研究人员制备出有效控制这类不期望生长的多种的化学品和化学制剂。多种化学除草剂描述于文献中,并且大部分是商购可得的。
已确定农业上的农药制造商们需要广谱、长效作用的农药产品。单个活性成分制剂很少符合这类需求,因此需要开发或许包含高达四种互补生物活性成分的组合产品。目前可以得到多种组合产品(即包含超过一种活性成分的产品),但是无一是一次施用产品能提供广谱、长季节的防治。
因此,本发明的目的是提供一种一次处理对不期望植物提供长季节防治的方法。
就其对植物生长的影响来说,用于本发明方法中的单个化合物各自是本领域已知的。例如,与大量的其它环己二酮化合物一起描述于U.S.专利号5,049,046的除草的环己二酮化合物2-(2′-硝基-4′-甲基磺酰基苯甲酰基)-1,3-环己二酮(甲基磺草酮)是选择性除草剂。乙酰胺类,尤其是2-氯-N-(2-乙基-6-甲基苯基)-N-(2-甲氧基-1-甲基乙基)乙酰胺(异丙甲草胺)是已知具有除草活性的化合物种类。草甘膦是非选择性除草剂,尤其是以商品名Touchdown来获得。尽管当施用于不期望植物时,所有的这些组分本身有除草活性,然而无一是一次施用能单独提供目前农业生产所需要的广谱、长季节的防治。
因此,本发明提供一种长季节防治不期望植物的方法,所述方法包括将包含2-(取代的苯甲酰基)-1,3-环己二酮或其金属螯合物、草甘膦或其盐以及乙酰胺的除草组合物一次施用至所述不期望植物的所在地。术语“长季节防治”指对任何作物每季仅需要施用除草组合物一次,则不期望的植物将在整个季节期间保持被控制。“季节”通常长达120天,例如40至120天,例如50至120天。
