Novel 1-substituted methyltetrazolinones of the formula (I) ##STR1## wherein R.sup.1 represents a 5-membered heterocyclic radical which has 1 to 3 heteroatoms selected arbitrarily from the group consisting of N, O and S and which is optionally substituted by halogen and/or C.sub.1-4 alkyl, or represents oxiran-2-yl, optionally chloro-substituted pyridyl or C.sub.1-4 alkyl-S(O).sub.m --wherein m represents 0, 1 or 2, or represents a C.sub.3-6 alicyclic hydrocarbon radical; R.sup.2 and R.sup.3 represent, independently of one another, C.sub.1-4 alkyl, C.sub.3-7 cycloalkyl or optionally substituted phenyl, or R.sup.2 and R.sup.3 may form, together with the N-atom to which they are bonded, an optionally substituted ring; R.sup.4 represents a hydrogen atom or methyl; and n represents 0 or 1; as well as for their preparation processes and novel intermediates in their production. The inventive compounds of formula (I) are used as herbicides.
