Herbicidal substituted thiadiazolyloxyacetamides of the formula ##STR1## in which R.sup.1 stands for hydrogen or for an optionally substituted radical from the group consisting of alkyl, alkenyl, alkinyl and aralkyl, R.sup.2 stands for an optionally substituted radical from the group consisting of alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aralkyl, aryl, alkoxy, alkenyloxy and alkinyloxy, or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are bonded form an optionally substituted, saturated or unsaturated heterocycle which can contain further hetero atoms and to which a benzo group can be fused, and R.sup.3 stands for an optionally substituted alkyl radical. Intermediates of the formulas ##STR2## in which R.sup.3 stands for optionally substituted alkyl, and X stands for S or SO.sub.2, are also new.
