Concentrated herbicide formulation, non-volatile, stable at low temperatures and soluble in water of 2,4-D acid ((2,4-dichlorophenoxy) acetic acid), characterized in that it includes: 45 to 75%, w/v of 2,4-D acid, in the form of a water soluble salt of a primary, secondary, or tertiary amine, or a primary, secondary, or tertiary alkanolamine, or a mixture of both; 1 to 40%, w/v of a humectant selected from a group made up of amine oxides, amide amine oxides, ethoxylated fatty amines, glycerin and its derivatives, sorbitol and its derivatives and polyethyleneglycol, and their mixtures; 0.1 to 20%, w/v of an antifreeze selected from a group made up of glycols; 0.01 to 0.5%, w/v of an antifoaming agent chosen from amongst silicon oil emulsions at 10-30%, surfactant agents based on hydrocarbons such as fatty acids and their salts in hydrocarbon, and alcohols with 8 or more carbon atoms, such as 2-ethylhexanol and isooctanol; optionally, 0.5-10%, w/v of a non-polar solvent; and the rest being water.
