Abstract

3-(2,3-Dichloro-3,3-difluoro-prop-1-en-1-yl)-2,2-dimethyl-cyclo-propanecarb oxylic acid fluoro-benzyl esters of the formula ##STR1## in which R.sup.1 represents hydrogen, cyano, alkyl with up to 4 carbon atoms, alkenyl with up to 4 carbon atoms or alkynyl with up to 4 carbon atoms, and PA1 R.sup.2 represents a phenyl radical which is substituted by fluorine and/or optionally fluorine-substituted phenoxy, with the proviso that the radical R.sup.2 in total contains at least one fluorine substituent, which possess pesticidal activity.
