  • Applications

    Penoxsulam (CAS 219714-96-2) is a sulfonamide herbicide used primarily in agriculture to control weeds in rice, applied in pre-emergence and post-emergence timings; as an ALS inhibitor it provides selective control of annual grasses and some broadleaf weeds in rice fields, supporting effective weed management while minimizing crop stress; it is commonly used in rice weed-management programs and is often included in tank mixes with other herbicides; outside rice it may be evaluated for use in other crops or cropping systems where registered, subject to local regulations and formulation limits.
