Abstract
There are disclosed novel unsubstituted or substituted phenoxyfluorobenzyltetramethylcyclopropylmethyl ethers of formula ##STR1## wherein Y is hydrogen, halogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkyl which is substituted by 1 to 9 halogen atoms, C.sub.1 -C.sub.4 alkoxy or C.sub.1 -C.sub.4 alkoxy which is substituted by 1 to 9 halogen atoms, C.sub.1 -C.sub.4 alkylthio or C.sub.1 -C.sub.4 alkylthio which is substituted by 1 to 9 halogen atoms, or is C.sub.2 -C.sub.4 alkenyl or C.sub.2 -C.sub.4 alkynyl and their benzyl ether intermediates of formula IV ##STR2## wherein X is halogen or p-tosyl. Also disclosed is a process for the preparation of these compounds and compositions containing them for use in pest control, especially for controlling insects that attack plants and animals, in particular their larval stages. The novel compounds are particularly effective against plant-destructive insects in rice crops.
