Oxaziclomefone is a selective herbicide used in agriculture, particularly for weed control in rice paddies. It belongs to the oxadiazole class and acts as a protoporphyrinogen oxidase (PPO) inhibitor, disrupting chlorophyll synthesis and causing rapid necrosis in susceptible weeds. Effective against broadleaf weeds and sedges, it provides post-emergence control without significant injury to rice crops when applied at recommended rates. This makes it valuable for integrated weed management in paddy fields, reducing labor-intensive manual weeding.
