Herbicidal compounds, compositions containing them, and a method for controlling weeds by application of the compositions are disclosed. The herbicidal compounds are 2-(1-aryl-4-cyano-5-pyrazolylmethyleneiminooxy)alkanoic acid derivatives of the structure: ##STR1## in which R is lower alkyl, lower alkenyl, or lower alkynyl, each optionally substituted with halogen, or CH(R.sup.1)--C(O)--Y--R.sup.2 ; R.sup.1 is hydrogen or lower alkyl; R.sup.2 is one of a variety of substituents; Y is O or NH; Z is lower alkyl or lower alkoxy; and Ar is 3-chloro-5-trifluoromethyl-2-pyridyl, 2,6-dichloro-4-trifluoromethylphenyl, or 2,4,6-trichlorophenyl.
除草化合物、含有它们的组合物以及通过应用这些组合物来控制杂草的方法已被披露。这些除草化合物是结构为2-(1-芳基-4-氰基-5-吡唑基甲亚氧基)烷酸衍生物的化合物:##STR1## 其中R是较低的烷基、较低的烯基或较低的炔基,每个都可以选择性地用卤素取代,或者CH(R.sup.1)--C(O)--Y--R.sup.2;R.sup.1是氢或较低的烷基;R.sup.2是多种取代基中的一种;Y是O或NH;Z是较低的烷基或较低的烷氧基;Ar是3-氯-5-三氟甲基-2-吡啶基、2,6-二氯-4-三氟甲基苯基或2,4,6-三氯苯基中的一种。
