Herbicidal mixture (A) contains: (1) tritosulfuron (I) or its salt; and (2) at least herbicide comprising florasulam, flucarbazone, propoxycarbazone, sulfosulfuron, amicarbazone, pethoxamid, mesotrione, mesosulfuron-methyl, iodosulfuron-methyl, foramsulfuron, flupyrsulfuron-methyl, beflubutamide, carfentrazone-ethyl, fluazolate and/or pyraflufen-ethyl (including their salts). ACTIVITY : Herbicide. In post-emergence tests against Alopecurus myosuroides, the herbicidal effect was 41% for (I) at 125 g/ha, 55% for propoxycarbazone sodium salt at 7.81 g/ha and 81% (compared with a calculated value (Colby) of 73%) for a combination of (I) at 125 g/ha and propoxycarbazone sodium salt at 7.81 g/ha.
