Abstract: The invention relates to novel fluorothiadiazolyloxyacetamides of the formula (I) ##STR1## in which R.sup.1 represents hydrogen or respectively optionally substituted alkyl, alkenyl, alkynyl or arylalkyl,R.sup.2 represents respectively optionally substituted alkyl, alkoxy, alkenyl, alkenyloxy, alkynyl, cycloalkyl, cycloalkenyl, aryl, arylalkyl or arylalkyloxy, orR.sup.1 and R.sup.2 together with the nitrogen atom that they are attached to form an optionally substituted saturated or unsaturated nitrogen heterocycle which may contain further hetero atoms and to which a benzo grouping may be fused, andR.sup.3 represents fluorothiadiazolyl,to a process and to novel intermediates for their preparation and to their use as herbicides.
