The invention relates to new benzoylurea compounds of the general formula <IMAGE> wherein R1 is a halogen atom, R2 is a hydrogen atom or a halogen atom, R3 is a hydrogen atom or represents 1 or 2 substituents which are selected from the group consisting of chlorine, methyl and trifluormethyl, R4 is a hydrogen atom or represents 1-3 substituents which are selected from the group consisting of halogen, and alkyl, alkoxy, haloalkyl and haloalkoxy, having 1-4 carbon atoms, X is N or CH, n is 0 or 1, and R5 is a hydrogen atom, an alkyl group having 1-6 carbon atoms, an alkenyl group having 2-6 carbon atoms, or a cycloalkyl group having 3-6 carbon atoms, with the proviso, that, if n is 0 and R5 is a hydrogen atom, R3 is a hydrogen atom. The compounds have an insecticidal and acaricidal activity. After having been processed to compositions, the compounds may be used for the control of insects and/or mites in a dosage of 1 to 5000 grams of active substance per hectare. In addition the compounds have an antitumor activity and may be used in pharmaceutical compositions. |
