This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,949.

Background and Problem Solved

The original patent disclosed stable, concentrated herbicidal compositions comprising glufosinate-ammonium. However, these formulations still have limitations, such as sensitivity to temperature, pH, and pressure fluctuations during preparation. The present invention addresses these limitations by introducing novel systems and methods for preparing and enhancing the stability and biological activity of herbicidal compositions.

Novelty and Inventive Step

The present invention provides a significant improvement over the original patent by introducing a controlled temperature mixing process, pH-adjusting agents, and optimized surfactant selection. These novel features ensure enhanced stability, biological activity, and user convenience, making the invention non-obvious and novel compared to the prior art.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include varying the type and amount of surfactants, adjusting the pH range, or using different organic solvents. Additionally, the invention could be adapted for use with other herbicidal active ingredients or in different crop protection applications.

Potential Commercial Applications and Market

The enhanced herbicidal compositions and systems of the present invention have significant commercial potential in the crop protection industry, offering improved stability, biological activity, and user convenience. The target market includes agricultural companies, farmers, and crop protection product manufacturers.
