The invention relates to new benzoyl ureas of the general formula
wherein R1 is a hydrogen atom, a chlorine atom, a fluorine atom or a methyl group,
R2 is a chlorine atom, a fluorine atom, or a methyl group,
R3 is a hydrogen atom or one or two substituents selected from the group consisting of a halogen atom and an alkyl group having 1 to 4 carbon atoms,
R. is a hydrogen atom or from one to three substituents selected from the group consisting of a halogen atom and an alkyl group, alkoxy group or alkylthio group having 1 to 4 carbon atoms and substituted or not substituted with halogen,
R5 and R6 are equal or different and represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms and substituted or not substituted with halogen, and
n is 0 or 1,
as insecticides.
After having been processed to compositions, the compounds can successfully be used for controlling insects in a dosage from 10 to 5.000 g of active substance per hectare.
