Abstract

5,6-Dihydro-1,2,4,6-thiatriazin-5-one-1,1-dioxides of the formula ##STR1## where R.sup.1 is hydrogen, a metal atom or an unsubstituted or substituted ammonium radical, PA0 R.sup.2 is a saturated or unsaturated straight-chain aliphatic radical of up to 10 carbon atoms, a cycloaliphatic radical or 3 to 7 carbon atoms, a branched saturated or unsaturated aliphatic radical of 3 to 10 carbon atoms, a halogen-, alkoxy- or alkylmercapto-substituted aliphatic radical of 2 to 10 carbon atoms tetrahydrofuryl substituted methyl, a cycloalkoxy-substituted aliphatic radical of 4 to 10 carbon atoms, unsubstituted or halogen-substituted benzyl or phenyl, halophenyl, or alkylphenyl of a total of up to 10 carbon atoms, PA0 R.sup.3 is hydrogen, a straight-chain aliphatic radical of up to 10 carbon atoms, a cycloaliphatic radical of 3 to 7 carbon atoms, a branched aliphatic radical of 3 to 10 carbon atoms, haloalkyl, or alkoxyalkyl of 2 to 10 carbon atoms and PA0 X is oxygen and may also be sulfur if R.sup.2 is unsubstituted or halogen-substituted benzyl, processes for their preparation, and herbicides containing the above compounds.
