Summary:Disclosed are solid, phytoactive, N-phosphonomethyl-N-carboxy-methyl compositions. Also disclosed are processes for the preparation of such compositions by (a) forming an initial mixture comprising a phytoactive N-phosphonomethyl-N-carboxymethyl compound, a solvent and a molten surfactant, the surfactant being solid at ambient temperatures; (b) removing solvent from the initial mixture to form a final mixture at a temperature above the melting point of the surfactant; (c) cooling said final mixture to a temperature below the melting point of the surfactant to form a N-phosphonomethyl-N-carboxymethyl composition which is solid at ambient temperatures; and (d) processing said composition into particulate form, such as pellets, flakes, granules, or powders. Further disclosed is the use thereof in controlling vegetation.
