Abstract

Substituted N-phenylthioureas, N-phenylisothioureas and N-phenylcarbodiimides of formula ##STR1## wherein R.sub.1 is C.sub.1 -C.sub.12 alkyl, C.sub.3 -C.sub.8 cycloalkyl, polycyclic alkyl containing a total of 7 to 10 carbon atoms, C.sub.1 -C.sub.12 alkyl which is substituted by 1 to 12 halogen atoms, C.sub.1 -C.sub.4 alkyl which is substituted by one or two C.sub.3 -C.sub.6 cycloalkyl radicals, alkoxyalkyl containing a total of 3 to 10 carbon atoms, C.sub.1 -C.sub.5 alkyl which is substituted by a phenyl radical, C.sub.1 -C.sub.5 alkyl which is substituted by a phenyl radical which is in turn substituted by one or two members selected from the group consisting of halogen, methyl, methoxy and ethoxy; or is C.sub.3 -C.sub.10 -alkenyl or C.sub.3 -C.sub.10 alkynyl, R.sub.2 is hydrogen or C.sub.1 -C.sub.4 alkyl, R.sub.3 is C.sub.1 -C.sub.4 alkyl, R.sub.4 is hydrogen or C.sub.1 -C.sub.4 alkyl, and R.sub.5 is a defined nitrogen-containing heterocyclic radical, and Z is a group selected from ##STR2## and salts thereof, the preparation of said compounds and compositions containing them for use in pest control.
