Procedure

A series of concentrated herbicide formulations were prepared as described above in Example 1 by combining glyphosate acid (technical grade, as a wet cake) with varying amounts of isopropyl amine ranging from a molar ratio glyphosate acid to isopropyl amine of 1:1 to 1:15. The resulting aqueous solutions were combined with a tallowamine ethoxylate (10 EO) and diluted with a sufficient amount of water to yield a concentrated glyphosate IPA salt formulation with 480 gae/l glyphosate and 110 g/l tallowamine ethoxylate. Table 3 provides a listing of the series of 62% glyphosate isopropylammonium salt components that were used to prepare the formulations, which ultimately contained 480 gae/l glyphosate isopropylammonium salt and 110 g/l tallowamine ethoxylate surfactant.
