  • Applications

    Oxasulfuron (CAS 144651-06-9) is a sulfonylurea herbicide used in agriculture for selective weed control in crops. It is formulated into herbicide products for pre- and post-emergence applications to suppress broadleaf and grassy weeds in cereal crops and some high-value crops, contributing to integrated weed management programs. In the agrochemical industry, it is evaluated and formulated by manufacturers for crop protection products and is commonly studied in research programs for new herbicidal solutions, with use governed by label directions and local regulations.
