A herbicidal composition is provided comprising an aqueous solution of N-phosphonomethylglycine, predominantly in the form of the monoethanolammonium salt thereof, at a concentration of about 30% to about 48% N-phosphonomethylglycine acid equivalent by weight. In a particular embodiment, a herbicidal composition comprises water; N-phosphonomethylglycine predominantly in the form of the monoethanolammonium salt thereof in solution in the water in an amount of about 360 to about 570 g a.e./l of the composition; and a surfactant component in solution or stable dispersion in the water, comprising one or more surfactants in a total amount of about 20 to about 200 g/l of the composition, this surfactant component being selected such that the composition has a cloud point not lower than about 50.degree. C.

[ What is claimed is:] [1.]1. A herbicidal concentrate composition comprising(1) water;(2) N-phosphonomethylglycine, predominantly in the form of the monoethanolammonium salt thereof, in solution in said water in an amount of about 360 to about 570 grams acid equivalent per liter of the composition; and(3) a surfactant component in solution or stable dispersion in said water, comprising one or more surfactants in a total amount of about 20 to about 200 grams per liter of the composition;wherein said surfactant component is selected such that the composition has a cloud point not lower than about 50.degree. C. and said surfactant component predominantly comprises one or more surfactants each having a molecular structure comprising(1) a hydrophobic moiety having one or a plurality of independently saturated or unsaturated, branched or unbranched, aliphatic, alicyclic or aromatic C.sub.3-8 hydrocarbyl or hydrocarbylidene groups joined together by 0 to about 7 linkages selected from ether, thioether, sulfoxide, ester, thioester and amide linkages, said hydrophobic moiety having in total a number J of about 8 to about 24 carbon atoms, and(2) a hydrophilic moiety comprising(i) an amino group that is cationic or that can be protonated to become cationic, having attached directly thereto 0 to 3 oxyethylene groups or polyoxyethylene chains, said oxyethylene groups and polyoxyethylene chains comprising on average no more than a number E of oxyethylene units per surfactant molecule such that E+J=25, and/or(ii) a glycoside or polyglycoside group comprising on average no more than about 2 glycoside units per surfactant molecule,said hydrophobic moiety being attached (a) directly to an amino group of said hydrophilic moiety, (b) to said hydrophilic moiety by an ether linkage incorporating an oxygen atom of one of said oxyethylene groups or of a terminal oxyethylene unit of one of said polyoxyethylene chains, or (c) to said hydrophilic moiety by an ether linkage to one of said glycoside units.
