Insecticide or miticide (especially for spider mites) composition comprising synergistic amounts of pyrethyroid and 4-bromo-2-(4-chlorophenyl)-1-(ethoxymethyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile, and methods of controlling insecticidal and miticidal pests

摘要

The insecticidal and miticidal composition comprises as active ingredients 4-bromo-2-(4-chlorophenyl)-1-(ethoxymethyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile and a pyrethyroid insecticidal ingredient(s), wherein the active ingredients are present in synergistically effective amounts. Also described is a method of controlling insecticidal and miticidal pests which have acquired resistance to 4-bromo-2-(4-chlorophenyl)-1-(ethoxymethyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile at a locus which comprises applying to the locus an effective amount of an insecticidal and miticidal composition that comprises as active ingredients 4-bromo-2-(4-chlorophenyl)-1-(ethoxymethyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile and a pyrethyroid insecticidal ingredient(s), wherein the active ingredients are present in synergistically effective amounts.
