Novel Ureas Abstract The present invention relates to novel N-phenyl-N-pyrimidin-2-ylureas having a herbicidal and plant growth-regulating activity, to agrochemical compositions containing those substances as active ingredients, to the use of the novel ureas for controlling weeds or for regulating plant growth, and to processes for the preparation of the novel compounds. The invention also relates to novel intermediates and to processes for the preparation thereof. The novel compounds correspond to formula I Image (I), in which R1, R2 and R3 are each, independently of the others, hydrogen; halogen; C1-C4alkyl; C1-C4alkoxy; C1-C4haloalkyl; C1-C4haloalkoxy; C1-C4alkyl- S(O)n-; nitro; cyano; C1-C4alkoxycarbonyl; C1-C4alkylcarbonyl; di- (C1-C4alkylamino)-carbonyl; mono-(C1-C4alkylamino)carbonyl; carbamoyl; C1-C4haioalkyl-S(O)n-; or -PO[O-(C1-C4)-alkyl]2; R4 is C1-C6alkyl; C1-C4alkoxy; C1-C4alkyl-S(O)n-; C1-C4haloalkyl; C1-C4haloalkoxy; phenyl that is unsubstitutsd or is substituted by up to three identical or different substituents from halogen, C1-C4alkyl, C1-C4haloalkyl and C1-C4alkoxy; 2-furanyl; 2-thienyl; 3-thienyl; C3-C6- cycloalkyl that is unsubstituted or ls substituted by up to three ideneical or different C1-C4alkyl radicals; cyano; C2-C4haloalkenyl; C1-C4alkoxy-C1-C4alkyl; C1-C4alkoxy-C1-C4alkoxy; or halogen-C1-C4alkyl- thio; R5 is hydrogen; C1-C3alkyl; C1-C3haloalkyl; halogen; or C1-C3haloalkoxy; and n is 0, 1 or 2, with the proviso that when one of the radicals R1, R2 and R3 is nitro, that substituent may not be bonded in tho 2- or 6-position of the phenyl ring.
