FIELD: agriculture, herbicides.
SUBSTANCE: invention relates to aqueous herbicidal concentrate compositions containing glyphosate or salt thereof dissolved in aqueous medium,, surfactant in solution or in form of stable suspension, emulsion or dispersion in said medium, oxalic acid or salt thereof wherein ratio of surfactant and oxalic acid or salt thereof is from 5:1 to 40:1 and ratio of glyphosate or salt thereof based on acidic equivalent and oxalic acid or salt thereof is from 2:1 to 125:1. Also disclosed are method for reducing of surfactant content in said composition including dilution thereof with water; method for suppression of imopea growth by applying of aqueous composition on imopea leaves, as well as solid herbicidal concentrate composition containing glyphosate ammonium salt, oxalic acid or salt thereof and surfactant.
EFFECT: compositions of increased effectiveness.
