Used as a fast-acting herbicide to control a broad spectrum of annual weeds and grasses in agriculture and aquatic environments. It is commonly applied for desiccation of crops like potatoes before harvest, helping to dry out foliage and promote uniform skin set. Also used in non-crop areas for vegetation management, including roadsides and industrial sites. Effective in water bodies to control floating and submerged weeds, though its use is regulated due to toxicity concerns. Acts by disrupting photosynthesis, leading to rapid plant tissue destruction upon contact. Often combined with other herbicides to enhance effectiveness or manage resistance.
