Abstract
This invention relates to a high-strength herbicidal formulation containing high concentrations of 2,4-D salt mixtures. The 2,4-D salt mixtures can include the DMA salt and the DMEA and/or the DEEA salt of 2,4-D. Selected combinations of the 2,4-D salt mixtures exhibit significantly greater low temperature stability at high concentrations.
Claims3
A stable, high-strength herbicidal formulation, which remains a clear, homogeneous liquid at temperatures as low as 0° C., comprising a mixture of a dimethylamine (DMA) salt of 2,4-dichlorophenoxy acetic acid (2,4-D) with a dimethylethanolamine (DMEA) salt or a diethylethanolamine (DEEA) salt of 2,4-D or a mixture thereof in a relative ratio of 2,4-D DMA salt to 2,4-D DMEA or DEEA salt of between about 55:45 to about 40:60, wherein the formulation contains at least 625 gram acid equivalents per liter (gae/L) to about 740 gae/L based upon the 2,4-D acid equivalent of the 2,4-D salt mixture.
