Abstract
Abstract 1-Aralkylpyrazoles of the formula ##STR1## in which Ar represents optionally substituted aralkyl, R 1 represents alkyl, R 2 represents hydrogen, alkyl, halogenoalkyl, optionally substituted benzyl, or the --COR 4 , --COOR 4 , --NR 5 R 6 or --CONR 5 R 6 radicals, where R 4 represents hydrogen, alkyl, halogenoalkyl or alkoxyalkyl, and R 5 and R 6 represent hydrogen and/or alkyl, R 3 represents hydrogen or alkyl, or R 2 and R 3 together represent the --Co--(CH 2 ) m --, --(CH 2 ) m --or --CH═CH--CH═CH-- groups, where m represents the numbers 2, 3, 4 or 5, and n represents the numbers 0, 1 or 2, which possess pesticidal activity.
