<p>The invention relates to new benzoylurea compounds of the general formula <IMAGE> wherein R1 is a hydrogen atom or represents 1 or 2 substituents which are selected from the group consisting of halogen and alkyl and haloalkyl having 1-4 carbon atoms, R2 is a hydrogen atom or represents 1 or 2 substituents which are selected from the group consisting of chlorine, methyl and trifluoromethyl, and R3 is a hydrogen atom or represents 1-3 alkyl and/or alkenyl groups each having 1-6 and/or 2-6 carbon atoms respectively, or wherein R3 together with the cyclohexyl ring to which it is attached forms a bi- or polycyclic hydrocarbyl group having 8-14 carbon atoms and, if desired, substituted with 1-3 alkyl groups each having 1-4 carbon atoms. 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 from 1 to 5000 g of active substance per hectare.</p> |
