Patent ID: 7989392

Claim:
An aqueous herbicidal composition useful for killing or controlling the growth of unwanted plants, comprising: glyphosate or a herbicidal derivative thereof; a bipyridilium or a herbicidal derivative thereof; and a surfactant component comprising at least one surfactant in a concentration sufficient to provide long term control of the unwanted plants by enhancing glyphosate absorption and translocation within a plant before leaf damage induced by the bipyridilium would interfere with further absorption and translocation of glyphosate; wherein the glyphosate (acid equivalent basis) and the bipyridilium (cation equivalent basis) are present in a weight ratio of between 26:1 and about 100:1 and wherein the glyphosate (acid equivalent basis) and the surfactant component are present in a weight ratio of between 3:1 and about 100:1.
