Patent ID: 6992045

Claim:
An aqueous pesticidal concentrate composition comprising: glyphosate or a salt or ester thereof dissolved in an aqueous medium, the glyphosate being present in a concentration that is biologically effective when the composition is diluted in a suitable volume of water to form an enhanced application mixture and applied to the foliage of a susceptible plant; a surfactant component in solution or stable suspension, emulsion, or dispersion in said medium, comprising one or more surfactants; and oxalic acid or a salt thereof in a concentration such that growth of the plant is controlled to a greater extent as compared to a plant treated with a reference application mixture devoid of oxalic acid and said salt but otherwise having the same composition as said enhanced application mixture, wherein said surfactant component and said oxalic acid and said salt are present in a weight ratio between about 5:1 and about 40:1.
