ABSTRACT NEW HERBICIDES DERIVED FROM ARYLOXYBENZENECARBOXYLIC ACID IMIDES A herbicide of the formula- Image (I) in which: - Z represents the nitrogen atom or a group -C(X')=, - W, Y, Y', X, Z' and X' represent the hydrogen atom, a halogen atom, a group NO2 or CN, a mono- or polyhalogeno- alkyl group such as CF3, or an alkyl or alkoxy group, _ R1 represents a halogen atom or a group X2R3 or NR4R5. - R2 represents the hydrogen atom, a halogen atom, a substituted alkyl group, an allyl or propargyl group, a group CN, a group NR4R5, a group C(X2)R7, a group C(X2)X3R8 or C(X2)NR4R5, a group SO2F, SO2OR8 or SO2NR4R5 or a group P(X2)R9R10, - R3 represents an optionally substituted alkyl group or an allyl or propargyl group, - R4 represents the hydrogen atom, an alkyl, cycloalkyl or phenyl group, these groups being optionally substituted, an allyl or propargyl group or an alkylcar- bonyl or alkylsulphonyl group, - R5 has one of the meanings given for R4 or rep- resents a cation or a group OR6, R6 being the hydrogen atom, a cation or an optionally substituted alkyl group, or R4 and R5 together form a alkylene group, - X2 and X3 represent the oxygen or sulphur atom, - R7 represents the hydrogen atom, a C1-12-alkyl cycloalkyl or phenyl group, these groups being optionally substituted, or an alkenyl or alkynyl group, - R8 represents a cation or has one of the mean- ings given for R7, and - R9 and R10, which are identical or different, represent the hydrogen atom, an optionally substituted alkyl group, a hydroxyl group or a group OM, M represent- ing a cation, or have one of the meanings given for R1, with the proviso that a) R2 is not COOCH3 if R1 is OCH3, W is NO2, Y' and Z' are H 2nd X is CF3, Y is Cl and Z is -CH=, and with the proviso that b) R2 is not H when X is NO2.
