Zusammenfassung:	New herbicides especially useful against weeds in cereals or soya, have the formula: in which: X1, X2 and X3 represent a halogen atom, such as fluorine, chlorine or bromine; a polyhalogenoalkyl radical; NO2; CN; an alkyl radical; an SO2-alkyl radical; SO2NH2; NO; or COO-alkyl, Y1 is -N= or -CH=, Y2 is -N= or, when Y1 is -CH=, a group CX7=; Y3 is the oxygen or sulphur atom; X4 is the hydrogen atom or a substituted or unsubstituted alkyl radical; X5 is the hydrogen atom; an alkali metal atom; a cationic quaternary or non-quaternary ammonium group; a substituted or unsubstituted alkyl radical; or a halogen atom; X6 is a substituted or unsubstituted alkyl radical, or an aryl radical, in particular a phenyl radical, which is substituted or unsubstituted; and X7 is the hydrogen atom or a halogen atom.
