ABSTRACT UREA COMPOUNDS, INTERMEDIATES AND PROCESS FOR THEIR PREPARATION, HERBICIDAL AND/OR FUNGICIDAL COMPOSITIONS, AND METHOD OF COMBATING UNDESIRED PLANT GROWTH Compounds of the general formula: Image (I) in which R1 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R2 represents a hydrogen atom, a methyl or a methoxy group; Ar represents an optionally substituted phenyl group or an optionally substituted heteroaromatic ring containing 1 or 2 oxygen, sulphur and/nitrogen atoms; each of X and Y independently represents a hydrogen or halogen atom or an alkyl, haloalkyl or alkoxy group; and one of A and B represents a group -CO-; -CR3(OR4)- or -CR3(SR4), in which R3 represents a hydrogen atom or an alkyl group and R4 represents a hydrogen atom, an alkyl, alkenyl, alkynyl or cycloalkyl group, an optionally substituted phenyl or benzyl group, or an acyl group derived from a carboxylic, sulphonic or phosphoric acid; -C(OR5)(OR6)-, -C(OR5)(SR6)- or -C(SR5)(SR6)-, in which each of R5 and R6 independently represents an alkyl group or together represent an alkylene group; -CH(CH8COOR7)- in which R7 represents an alkyl group; or -(CNR8)- in which R8 represents a group OR4 or NHR4; and the other of A and B represents a group -CR9R11-CR10R12-, in which each of R9, R10, R11 and R12 independently represents a hydrogen atom or an alkyl group or R11 and R12 together represent a carbon-carbon bond, a -CH2- group or an oxygen atom exhibit herbicidal and fungicidal properties.
