New benzoyl urea compound, the production manner and the insecticidal miticidal agent composition null which contains benzoyl urea compound

摘要

The invention relates to new benzoylurea compounds having insecticidal and acaricidal activity, of the general formula CHEM wherein R1 is a hydrogen atom or represents 1 or 2 halogen atoms; Ar is a para-phenylene group or a para-pyridylene group, which groups may be substituted with 1 or 2 substituents selected from the group consisting of chlorine, methyl and trifluoromethyl; B is an oxygen atom or represents a group having the formula CHEM or CHEM wherein R2 is a hydrogen atom or an alkyl group having 1-4 carbon atoms; and R is a cycloalkyl group, a cycloalkenyl group having 6-12 carbon atoms, which groups may be substituted with 1-3 substituents selected from the group consisting of alkyl and alkenyl having 1-6 carbon atoms, or wherein R is a bi- or polycyclic, saturated or unsaturated, hydrocarbyl group, having 8-14 carbon atoms and, if desired, substituted with 1-3 substituents selected from the group consisting of alkyl and alkenyl having 1-6 carbon atoms; with the proviso, that, if Ar is a whether or not substituted paraphenylene group, and R is a whether or not substituted cyclohexylgroup, or a saturated bi- or polycyclic hydrocarbyl group having 8-14 carbon atoms. then B does not represent an oxygen atom.
