A recently granted patent (Publication Number: US11910795B2) discloses a broadleaf weed herbicidal composition designed to selectively target broadleaf weeds while being less toxic to turf grasses. The composition includes natural indole auxins, chelating agents, and emulsifiers in specific weight ratios. The natural indole auxins can be indole-3-acetic acid, indole-3-butyric acid, or indole-3-propionic acid, along with suitable salts. The chelating agents consist of aminopolycarboxylic acids like ethylenediaminetetraacetic acid (EDTA) or its salts. Emulsifiers such as sorbitan fatty acid ester ethoxylate are also included. The composition can contain additional agriculturally suitable adjuvants like humectants, penetrants, pigments, or wetting agents, with specific weight ratios to the main components.

Moreover, the patent also covers a method for selectively controlling broadleaf weeds on turfgrass using the disclosed composition. By applying the natural indole auxins, chelating agents, and emulsifiers to the broadleaf weeds, turfgrass, or the surrounding growing medium, the combination effectively targets broadleaf weeds while minimizing harm to turf grasses. The method specifies the concentration ranges of the components and emphasizes the selective toxicity of the composition towards broadleaf weeds. Overall, the patent provides a comprehensive solution for managing broadleaf weeds in turfgrass areas, offering a targeted and environmentally friendly approach to weed control.
