Abstract: Novel substituted N-4-(3-bromoallyloxy)-phenyl-N'-benzoylureas of the formula ##STR1## wherein R.sub.1 and R.sub.2 independently of one another are each hydrogen, chlorine or bromine, R.sub.3 is fluorine or chlorine, and R.sub.4 is hydrogen, fluorine or chlorine; processes for producing these compounds, as well as compositions containing them, for use in combating pests, particularly in combating insects which infest plants and animals. The novel compounds have a strong toxic and/or development-inhibiting action in particular against larval stages of insects which damage plants.
