Abstract:
1. A clear, homogenous, stable high-strength herbicidal concentrate composition, having a viscosity of less than 140 centipoise, consisting essentially of: (a) water, (b) glyphosate, predominantly in the form of the monomethylamine or the dimethylamine salt, in solution in the water in an amount of greater than about 350 grams of acid equivalent per liter of the composition, and (c) at least one surfactant in a total amount of about 20 to about 200 grams per liter of the composition in which the surfactant is a) an alkyletheramine surfactant having the chemical formula  in which R b) a quaternary ammonium surfactant having the chemical formula  in which Z is an agriculturally acceptable anion and R c) an amphoteric surfactant having the chemical formula  in which R d) an alcohol ethoxylate having the chemical formula  in which formula R e) an alcohol ethoxylate phosphate ester having the chemical formula  in which formula R f) an alkylpolyglycoside having the general chemical formula  in which the polyglycoside is derived from glucose or other mono-, di- or polysaccharides, n is the degree of polymerisation and is typically within the range from 1 to 3, and R g) an anionic ester derivative of alkylpolyglycosides having the chemical formula  in which the polyglycoside is derived from glucose or other mono, di- or polysaccharides, n is the degree of polymerisation and is typically within the range from 1 to 3, R h) mixtures thereof.
