Abstract: 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.

Abstract: A solid herbicidal formulation of N-(phosphonomethyl)glycine is described, in powder, granule, or flake form, soluble or dispersible in water, is described, containing Glyphosate (N-(phosphonomethyl)glycine) in the form of hydrosoluble salt and also including 5% to 30% in weight of one or more tensioactive agents, soluble in water, compatible with glyphosate and which are solid at ambient temperature, i.e. at approximately 25.degree. C. The process for preparation of said herbicidal formulation is also described.

Abstract: A solid herbicidal formulation of N-(phosphonometyl)glycine is described, in powder, granule, or flake form, soluble or dispersible in water, is described, containing Glyphosate (N-(phosphonomethyl)glycine) in the form of hydrosoluble salt and also including 5% to 30% in weiglit of one or more tensioactive agents, soluble in water, compatible with glyphosate and which are solid at ambient temperature, i.e. at approximately 25° C. The process for preparation of said herbicidal formulation is also described.
