FIELD: agriculture.SUBSTANCE: invention relates to agricultural chemical compositions. Herbicidal compositions comprising (a) fluroxypyr or an agriculturally acceptable salt or ester thereof and (b) flumetsulam or an agriculturally acceptable salt thereof, provide synergistic herbicidal control of undesirable vegetation, where the weight ratio (a) to (b) ranges from 1:1.2 to 6:1. Herbicidal compositions provide control of undesirable vegetation in wheat, barley, oats, rye, sugarcane, rice, sorghum, corn/maize, soybean, rice, sunflower, canola/oilseed rape, sugarcane, sorghum, cotton, and also on pastures, grasslands, rangelands, fallowland, turf, tree and vine orchards, in industrial vegetation management and rights-of-way, or crops comprising an aad-12 gene. Invention also relates to methods of using herbicidal compositions containing (a) fluroxypyr or an agriculturally acceptable salt or ester thereof and (b) flumetsulam or an agriculturally acceptable salt thereof.EFFECT: herbicidal compositions containing
