New N-benzoyl-N'-(tetrazolyl-phenyl)-urea derivatives, useful as pesticides e.g. insecticides, acaricides, nematocides, ectoparasiticides, antifouling agents, herbicides, fungicides and bactericides

摘要

N-(2-Halo- or 2,6-dihalo-benzoyl)-N'-(tetrazolyl-phenyl)-urea derivatives (I) are new. Urea derivatives of formula (I) are new. R1 = H or halo; R2 = halo; R3 = halo, alkyl or haloalkyl; n = 0-2, and R4 = H, alkylsulfonyl or diaminocarbonyl (sic); or alkyl, alkenyl, aryl, arylalkyl, arylsulfonyl, cycloalkyl, cycloalkylalkyl, heterocyclyl or heterocyclylalkyl (all optionally substituted).
