wherein R, represents a halogen atom or haloalkyl group; R2 and R3, which may be the same or different, each independently represents a hydrogen or halogen atom or a nitro, cyano or haloalkyl group;
one of Y and Z represents a nitrogen atom or an oxide thereof, and the other also represents a nitrogen atom or oxide thereof or alternatively represents the group CR4;
X represents an oxygen or sulphur atom, a carbonyl, thiocarbonyl or sulphonyl group or a group NRG or CIR4)2; R4 represents a hydrogen atom or a mercaptan, hydroxyl, alkoxy, alkylthio, alkylsulphonyl, alkyl, haloalkyl, amino, imino, alkylureido, alkylcarbonyloxyalkyl, alkoxycarbonylalkylthio, or alkylcarbamoyl group, provided that when two groups R4 are attached to the same carbon atom, then said groups are not both hydroxyl, mercaptan or alkylthio; and
R5 represents a hydrogen atom or a hydroxyl, alkoxy, alkylsulphonyl, alkyl, haloalkyl, amino, imino, alkylureido, alkylcarbonyloxyalkyl or alkylcarbamoyl group. Process for preparing such compositions, herbicidal compositions containing them, and their herbicidal use.
