CAS Number: 74223-64-6
Metsulfuron Methyl is a sulfonylurea herbicide that inhibits acetolactate synthase (ALS), disrupting the biosynthesis of branched-chain amino acids in susceptible broadleaf weeds and some grasses. Applied at very low rates, it provides effective post-emergence control in wheat, barley, and non-agricultural areas. Metsulfuron Methyl is absorbed rapidly through foliage and roots, with rapid translocation to growing points. AB Enterprises supplies Metsulfuron Methyl technical grade to formulators developing WG and WP herbicide products. Its low use rate, cost-effectiveness, and strong weed control profile make it a preferred herbicide for cereal crop and industrial weed management.
