Abstract

3-Phenoxybenzyl alcohols and carboxylic acid esters thereof for combating pests of the formula ##STR1## in which R and R.sup.1 are different and each represent hydrogen, fluorine or bromine, PA0 R.sup.2 represents cyano or ethynyl and PA0 R.sup.3 represents the ##STR2## or the ##STR3## wherein the phenyl ring can optionally carry one or more substituents selected independently from halogen, alkyl, alkylthio and alkoxy with in each case 1 to 4 carbon atoms, nitro and methylenedioxy, and PA0 R.sup.4 and R.sup.5 are identical and each represent chlorine, bromine or methyl, and PA0 R.sup.2 represents hydrogen in case that PA0 R.sup.3 represents the ##STR4## wherein R.sup.4 and R.sup.5 are identical and each represent chlorine or bromine and PA0 R.sup.3 represents the ##STR5## wherein the phenyl ring can carry the above mentioned substituents which possess insecticidal and acaricidal properties. The benzyl alcohols from which the esters are made are also new.
