Abstract
Abstract The invention provides new 4-amino-5-thione-1,2,4-triazine (4,5-H) of the formula ##STR1## in which R is alkyl of up to 8 carbon atoms, cycloalkyl of from 5 to 7 carbon atoms, cycloalkenyl of from 5 to 7 carbon atoms, phenyl, which can optionally be mono-substituted or polysubstituted by halogen, or alkoxyalkyl of from 1 to 4 carbon atoms per alkyl and alkoxy moiety, and R' is hydrogen or alkyl of up to 4 carbon atoms; Which are outstandingly effective as herbicides, particularly as selective herbicides.
