    Patent number: 4715888
    Abstract: The new synergistic active compound combinations consisting of (1) a photosynthesis-inhibiting active compound (herbicide) and (2) a pyridinecarboxamide of the general formula (synergistic agent) ##STR1## in which R represents alkyl, halogen, nitro, cyano, alkoxy, optionally substituted phenyl or optionally substituted benzyloxy, and the index n represents the numbers 0, 1, 2 or 3, have a particularly high herbicidal activity. Representative examples of the photosynthesis-inhibiting active compounds are metribuzin, ametridione, methabenzthiazuron, linuron, lenacil, atrazine and 4-amino-6-tert.-butyl-3-ethylthio-1,2,4-triazine-5-one.
