| 摘要 |
The invention relates to an insecticidal and miticidal composition which contains as active ingredients chlorfenapyr (4-bromo-2-(4-chlorophenyl) 1-(ethoxymethyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile in combination with one or more compounds selected from the organophosphoric acid ester-type compounds represented by general formulae (I) or (II), wherein X represents oxygen or sulfur atom, Y represents oxygen or sulfur atom, group or single bond represented by -S(CH2)nS- (n is 1 or 2), R<1> represents C1-C6 alkyl group, R<2> represents C1-C8 alkoxy group, C1-C8 alkylthio group, C1-C4 alkylcarbonylamino group, C1-C6 alkylamino group or phenyl group, and R<3> represents C1-C8 alkyl group, C2-C6 alkenyl group, amino group, phenyl group, or heteroaryl group, which are substituted by 1 to 4 same or different substituents selected from the substituent group A mentioned below or formula (III) (wherein R<1>, R<2> and X mean the same as the above-mentioned) or unsubstituted. Substituent group A: C1-C8 alkyl group, C1-C8 alkoxy group, C1-C6 aliphatic acyl group, C1-C6 alkoxy-carbonyl group, C1-C6 alkylthio group, C1-C6 alkylamino group, di-C1-C6 alkylamino group, C1-C4 alkylsulfinyl group, C1-C4 haloalkyl group, N-C1-C4 alkylcarbamoyl group, N,N-di-C1-C4 alkylcarbamoyl group, N-C1-C4 alkyl-N-formylcarbamoyl group, heteroaryl group which may be substituted, phenyl group which may be substituted, halogen atom, nitro group, cyano group, hydroxy group and acetylamino group. The insecticidal and miticidal composition of the invention is effective against pests and mites having resistance to commercial insecticidal and miticidal agents.
