Edoxaben is a selective pre-emergent herbicide used to control annual grasses and broadleaf weeds in ornamental landscapes and other non-crop areas. However, the manufacturing process of edoxaben can lead to the presence of impurities in the final product. These impurities can potentially impact the efficacy and safety of the herbicide. Therefore, it is important to closely monitor and control the levels of edoxaben impurities during the production process.
