Abstract: Described are compositions and methods for regulating plant growth that use a complex of an imidazolinone ion and a metal counterion; the compositions and methods include methods of regulation plant growth, optionally in combination with herbicidal, fungicidal, and fertilizer compositions and effects.

Abstract: The present invention provides a low viscosity, aqueous concentrate comprising a primary amine salt of glyphosate and surfactant. The aqueous concentrate can be formed from a highly concentrated glyphosate composition that has very low levels of glyphosate in non-salt form. Exemplary aqueous concentrates include a primary amine salt of glyphosate in the range of 45 percent weight to 68 percent weight, and a surfactant at a concentration in the range of 3 percent weight to 27 percent weight, with the concentrate having a viscosity in the range of 40 to 450 centistokes.

Abstract: The present invention provides a high-strength glyphosate salt aqueous concentrate and a method for forming the concentrate. The method uses high purity and low water content glyphosate acid and primary amine preparations. The glyphosate acid and primary amine are reacted in the presence of a nominal amount of water. The method provides a concentrate with a very high concentration of biologically effective glyphosate salt, and a minimal amount of biologically ineffective glyphosate acid particulates. The minimal amount of particulates improves the viscosity of the concentrate to commercially acceptable levels, and the beneficial properties associated with the concentrate can be carried over into excipient-containing concentrates and application compositions that are formed from the high-strength glyphosate salt aqueous concentrate.
