<p>2-Substituted benzazoles of the formula in which R represents optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, optionally substituted aryl or optionally substituted aralkyl, R1, R2, R3 and R4 independently of one another represent hydrogen, halogen, optionally halogensubstituted alkyl, optionally halogen-substitu-ted alkoxy, nitro, cyano, alkylcarbonyl or alkoxycarbonyl, or two radicals in combination form a benzo radical, X and Y independently of one another represent oxygen or sulphur and n represents zero or 1, synergize conventional pesticides. Those benzazoles in which R is -CH2-C?CH, R1, R2, R3 and R4 represent independently of one another hydrogen or halogen (preferably chlorine), Y represents oxygen and n represents 1, are new and exhibit particularly high synergistic activity.</p> |
