Herbicides of the formula (I): L-SO2-NH-CO-NR6-A in which: L denotes one of the groups of the formulae L-1 to L-6 given below, A denotes the group of the formula (II) given below, IMAGE L-1 IMAGE L-2 IMAGE L-3 IMAGE L-4 IMAGE L-5 IMAGE L-5 IMAGE (A) R1, R2 and R3 can be identical or different and represent a C1-C4 alkyl radical or a C7-C11 aralkyl radical, especially benzyl; R7, R8 and R9 can be identical or different and represent a hydrogen or halogen atom, a C1-C4 radical which is optionally substituted by one or more halogen atoms or C1-C4 alkoxy or C1-C4 alkylthio radicals, C3-C6 cycloalkyl which is optionally substituted by one or more halogen atoms or C1-C4alkoxy or C1-C4 alkylthio radicals, C1-C4 alkoxy or C1-C4 alkylthio which are optionally substituted by one or more halogen atoms or C1-C4 alkoxy or C1-C4 alkylthio radicals, R13 S(O)n-, n being an integer equal to 1 or 2 and R13 being a C1-C4 alkyl radical which is optionally substituted by one or more halogen atoms or C1-C4 alkoxy or C1-C4 alkylthio radicals, COOR14, where R14 is a hydrogen atom, a C1-C4 alkyl or C3-C6 cycloalkyl radical which is optionally substituted by one or more halogen atoms or C1-C4 alkoxy or C1-C4 alkylthio radicals, C3-C6 alkenyl which is optionally substituted by one or more halogen atoms, R10 and R11 can be identical or different and have the same means as R7, with the exception of the halogen atom. m denotes 0 or 1. Z is the oxygen atom, the sulphur atom or the group =N-R12. R12 is a C1-C6 alkyl, C6-C10 aryl or C7-C11 aralkyl radical, preferably methyl. X is a trivalent radical, -CH= or -N=, preferably -N=. R4 and R5 are identical or different and represent a C1-C4 alkyl radical (preferably methyl), C1-C4 alkoxy radical (preferably methoxy), C1-C4 alkylthio radical (preferably methylthio), C1-C4 haloalkyl radical (preferably trifluoromethyl), C1-C4 haloalkoxy radical (preferably di- or trifluoromethoxy), C1-C4 haloalkylthio radical (preferably trifluoromethylthio), C2-C6 alkoxyalkyl radical (preferably methoxymethyl, C2-C6 alkoxyalkoxy radical (preferably methoxymethoxy), C1-C4 alkylamino radical, di(C1-C4 alkyl)amino radical or a halogen atom (preferably chlorine). R6 represents the hydrogen atom or a C1-C4 radical (preferably methyl), advantageously, R6 is the hydrogen atom and the agriculturally acceptable salts of these compounds.
