Provided herein are herbicidal compositions comprising a mixture comprising (a) a choline salt of 2,4-dichlorophenoxyacetic acid (2,4-D-choline) and (b) a salt of 2-amino-4-(hydroxymethylphosphinyl) butanoic acid (glufosinate). The compositions provide synergistic weed control of undesirable vegetation and improved crop tolerance in 2,4-D-and glufosinate-tolerant soybeans, corn, or cotton. The compositions also provide synergistic weed control of undesirable vegetation in areas including, but not limited to, non-crop, perennial crop, fruiting crop, and plantation crop areas.此處提供除草劑組成物包含一混合物含有(a)2,4-二氯苯氧基乙酸之膽鹼鹽(2,4-D-膽鹼)及(b)2-胺基-4-(羥基甲基膦基)丁酸(草銨膦)之鹽。該等組成物提供在耐2,4-D與草銨膦的大豆、玉米、或棉花中非所欲植被之協同性雜草控制及改良的作物耐受性。該等組成物也提供在包括但非僅限於非作物、多年生作物、結果實作物、及種植作物區之區域中非所欲植被之協同性雜草控制。
