Pyroxasulfone is a pre-emergent herbicide used in agriculture to control a broad spectrum of weeds in various crops. Its mode of action involves inhibiting the enzyme acetolactate synthase, crucial for amino acid synthesis in plants, leading to weed death. Pyroxasulfone’s long-lasting residual activity and low application rates make it effective in weed management while minimizing environmental impact and crop damage.
