  • Applications

    Propanil is primarily used as a selective herbicide in rice production to control annual grasses and some broadleaf weeds. It acts by inhibiting photosynthesis in susceptible plants and is commonly formulated for spraying as emulsifiable concentrates (EC) or wettable powders (WP); it is applied to flooded rice fields, typically pre- or post-emergence depending on the product and local guidelines. Usage is subject to regulatory requirements and formulation limits.
