Weed management is a common practice in golf courses, home lawns, and sod production systems. Sulfonylurea (SU) herbicides were initially introduced in the agricultural market in 1982; however, SUs were also evaluated for control of weeds and overseeded grasses. Later, SUs were evaluated for selective control of broadleaf weeds, sedges, and kyllinga species in cool- and warm-season turfgrasses. In the 1990s, chlorsulfuron and metsulfuron were registered for selective control of broadleaf weeds, such as wild garlic, spotted spurge, and difficult-to-control grasses, such as bahiagrass in turfgrass. Now, there are several SUs registered for specific weed management in both cool- and warm-season turfgrasses. The current status of SUs, along with potential benefits and drawbacks in using these herbicides for weed management practices, are discussed. The research findings, possible recommendations in relation to the safety of turfgrass (established and overseeding stands), environmental concerns (persistence and lateral movement), and management practices in cool- and warm-season turfgrasses are discussed, including the potential evolution of weed resistance.

Nomenclature: Chlorsulfuron; metsulfuron; bahiagrass, Paspalum notatum Fluggé; spotted spurge, Chamaesyce maculata (L.) Small; wild garlic, Allium vineale L.
