Herbicidal carboxamide derivatives

The invention provides compounds of the general formula in whichR1 represents a hydrogen or halogen atom or an alkyl or haloalkyl group;the or each group X independently represents a halogen atom or an optionally substituted alkyl or alkoxy group or an alkenyloxy, alkynyloxy, cyano, carboxy, alkoxycarbonyl, (alkylthio)carbonyl, alkylcarbonyl, amido, alkylamido, nitro, alkylthio, haloalkylthio, alkenylthio, alkynylthio, alkylsulphinyl, alkylsulphonyl, alkyloximinoalkyl or alkenyloximinoalkyl group;n is 0 or an integer from 1 to 5; andL is an alkoxy group.

Herbicidal carboxamide compounds

Compounds of the formula STR1 wherein n is 1 to 5 and the/each X is hydrogen, halogen, cyano, nitro, optionally substituted alkyl or alkoxy alkenyloxy, alkynyloxy, haloalkylthio, alkenylthio or alkynylthio; m is 0 or 1 to 3 and the/each Y is halogen, alkyl or haloalkyl; Z is oxygen or sulphur; and R1 and R2 each, independently, is hydrogen, alkyl optionally substituted by halogen, hydroxy, cyano, alkoxy, alkylthio, alkoxycarbonyl, or mono- or di-alkylamino, alkenyl, alkynyl, hydroxy, alkoxy, alkenyloxy, alkynyloxy, alkoxycarbonyl, amino, mono- or di-alkylamino, alkoxycarbonylamino, arylamino, dialkylcarbamoyl, cycloalkyl, or optionally substituted cycloalkylalkyl; or R1 and R2 together form an alkylene chain optionally interrupted by oxygen, sulphur or --NR--, R being hydrogen or alkyl; are herbicides.
