Novel benzoylaminophenylureas of the formula <IMAGE> wherein R1 is hydrogen, halogen, CF3 or C1-C4alkoxy, R2 is halogen, C1-C4alkyl, CF3 or C1-C4alkoxy, R3 is hydrogen, halogen, CF3 or methyl, R4 is fluorine or chloride, R5 is hydrogen, fluorine or chlorine, R6 and R7 are each independently of the other C1-C6alkyl, C3-C5alkenyl, C3-C5alkynyl, or C1-C4-alkyl which is substituted by 1 to 8 fluorine or chlorine atoms or by methoxy or ethoxy; or R6 and R7, together with the nitrogen atom to which they are attached, are the radical <IMAGE> are prepared from novel amines. Compositions containing the novel ureas are used for controlling insects and representatives of the order Acarina. The novel ureas have larvicidal action, in particular against plant-destructive insects. |
