Abstract

Isoxazole(isothiazole)-5-carboxamides of the formula ##STR1## where X is oxygen or sulfur, PA1 R.sup.1 is hydrogen, substituted or unsubstituted alkyl, alkoxy, substituted or unsubstituted cycloalkyl, a 5- or 6-membered heterocyclic radical having one or two heteroatoms selected from the group consisting of oxygen, sulfur and nitrogen, and which may be substituted, or substituted or unsubstituted phenyl, or PA1 R.sup.2 is formyl, 4,5-dihydrooxazol-2-yl or a radical of the formula COYR.sup.5 or CONR.sup.6 R.sup.7, where PA2 Y is oxygen or sulfur, PA2 R.sup.5 is PA3 hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, haloalkenyl, substituted or unsubstituted alkynyl, PA3 cycloalkyl, PA3 cycloalkenyl, PA3 substituted or unsubstituted phenyl, PA3 a 5- or 6-membered heterocyclic radical having one or two heteroatoms selected from the group consisting of oxygen, sulfur and nitrogen, PA3 cycloalkanimino, phthalimido, succinimido, or a radical ##STR2## R.sup.3 and R.sup.4 have the meanings defined herein, or their agriculturally acceptable salts possess herbicidal activity.
