  • Patent number: 5591765
    Abstract: This invention relates to new insecticidal and synergistic miticidal compositions containing as essential active ingredients an arylpyrrolecarbonitrile or arylnitropyrrole and an arylpyrazolecarboxamide. The invention also relates to a method for protecting growing plants from infestation and attack by insects and plant mites comprising applying to the foliage and stems of said plants an insecticidally and miticidally effective amount of a composition containing a synergistic mixture of an arylpyrrolecarbonitrile or arylinitropyrrole and an arylpyrazolecarboxamide dispersed in an inert diluent, or sequentially applying to the foliage and stems of plants which are to be protected from attack by insects and plant mites, an arylpyrazolecarboxamide and a synergistically effective amount of an arylnitropyrrole or arylpyrrolecarbonitrile.
