The new synergistic combinations of active ingredients consisting of (1) a photosynthesis inhibitor active ingredient (herbicide) and (2) a 1,4-disubstituted pyrazole derivative of the general formula (II) (synergist), <IMAGE> (wherein R¹ and R² are those in the Description have given meaning), have a particularly high herbicidal activity. A particularly characteristic example of the photosynthesis inhibitor active ingredients is 4-amino-6-tert-butyl-3-methylthio-1,2,4-triazin-5-one (metribuzin). |
