Abstract
Abstract 3-Phenoxy-fluoro-benzyl carboxylic acid esters of the formula ##STR1## in which R 2 is hydrogen, cyano or ethynyl, R 3 is ##STR2## R 4 and R 5 represent chlorine, bromine or methyl, and R 6 is phenyl or phenyl substituted with halogen, alkyl with 1 to 4 carbon atoms, alkoxy with 1 to 4 carbon atoms, nitro or methylenedioxy, which possess arthropodicidal properties. The alcohols are also new.
