A herbicidal composition comprising a herbicidally effective amount of (a) a compound of the formula (I):

or an agriculturally acceptable salt or alkyl ester or benzyl ester thereof and (b) glufosinate-ammonium, glyphosate dimethylammonium, glyphosate isopropylammonium, glyphosate trimesium, glufosinate or glyphosate, or a salt or ester thereof wherein (a) and (b) are present in the composition in a ratio such that the composition exhibits herbicidal synergy.

A method of controlling undesirable vegetation which comprises contacting the vegetation or the locus thereof with, or applying to the soil or water to prevent the emergence or growth of vegetation, a combination comprising (a) a compound of the formula (I);

or an agriculturally acceptable salt or ester thereof and (b) a compound selected from:
glufosinate ammonium, glyphosate dimethylammonium, glyphosate isopropylammonium, glyphosate trimesium, glufosinate and glyphosate, or a salt thereof wherein (a) and (b) are present in the combination in a ratio such that the combination exhibits herbicidal synergy wherein the undesirable vegetation is controlled in direct-seeded, water-seeded and transplanted rice, cereals, wheat, barley, oats, rye, sorghum, maize, pastures, grasslands, rangelands, fallowland and turf.
