  • Applications

    Pyroxsulam (CAS 422556-08-9) is a selective post-emergence herbicide used in cereal crops to control annual grasses and certain broadleaf weeds. As an ALS (acetolactate synthase) inhibitor, it is applied in tank-mixed or sequential formulations to protect crops such as wheat and barley. It is formulated for foliar spray in field applications and is commonly integrated into weed-management programs as part of resistance-management and IPM strategies. Its use is typically restricted to cereal crops and is subject to local regulations and formulation limits.
