SYNERGISTIC HERBICIDAL WEED CONTROL AND IMPROVED CROP TOLERANCE FROM COMBINATIONS OF 2,4-D-CHOLINE AND GLUFOSINATE IN 2,4-D- AND GLUFOSINATE-TOLERANT SOYBEANS, CORN, COTTON

摘要

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.

1. A method of controlling undesirable vegetation and improving crop tolerance in 2,4-D- and glufosinate-tolerant soybeans, corn, or cotton, comprising contacting undesirable vegetation and 2,4-D- and glufosinate-tolerant soybeans, corn, or cotton or the locus thereof, or foliage, water or soil, with a composition comprising a mixture comprising a synergistic, herbicidally effective amount of:
(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)
