Novel substituted N-(p-aminophenyl)-N'-benzoyl ureas of the formula <IMAGE> wherein each of R1 and R2 independently is C1-C4alkyl or C3-C5alkenyl, each of R3 and R4 independently is chlorine or bromine, and each of R5 and R6 independently is hydrogen, fluorine or chlorine, with the proviso that R5 and R6 are not both simultaneously hydrogen, processes for the manufacture of these compounds and compositions containing them for use in pest control, especially for controlling insects harmful to plants and animals. The novel compounds inhibit feeding damage and have in particular a pronounced ovolarvicidal and ovicidal action against plant-destructive insects. |
