Used as a selective herbicide in agriculture and horticulture, particularly for controlling broadleaf weeds in cereal crops, lawns, and turf. It functions by mimicking plant growth hormones, causing uncontrolled growth in susceptible plants, leading to their death. Effective at low application rates and commonly found in weed control formulations for pastures, rice fields, and non-crop areas. Its sodium salt form enhances water solubility, allowing for easy mixing and spraying in aqueous solutions.
