UA88063C2 - Use of n-(4-pyridyl)methylsulfonamides for combating harmful arthropodes - Google Patents

Abstract

The present invention relates to the use of N-(4-pyridyl)methylsulfonamides of the formula for combating arthropodal pests (harmful arthropodes) and for protecting materials against infestation and/or destruction by said pests: where the substituents are as follows: Ris hydrogen, С-С-alkyl, С-С-аlkoxy, C-C-alkenyl, С-С-аlкуnуl or benzyl; R, R, R, Rindependently of one another are hydrogen, halogen, С-С-alkyl, С-С-alkoxy, С-С-haloalkoxy or С-С-haloalkyl; Rand Ror Rand Rtogether with the carbon atoms to which they are attached may also, form a condensed 5- or 6-membered hydrocarbon ring, it being possible for the hydrocarbon ring to carry one or two groups R, R, R, Rindependently of one another are halogen, С-С-alkyl, С-С-alkoxy, halomethoxy or halomethyl; X is a cyclic radical selected from phenyl, naphthyl and five- or six-membered saturated, partially unsaturated or aromatic heterocycles, the heterocycle being attached to the sulfur atom via a carbon atom and containing 1 , 2 or 4 heteroatoms selected from the group consisting of O, N and S, where the cyclic radical X may carry 1 , 2, 3 or 4 substituents R.I
