| Abstract/Contents: | "In the beginning there were two sulfonylurea (SU) herbicides in turfgrass, chlorsulfuron and metsulfuron. Chlorsulfuron, introduced in the 1990s under the trade name Lesco TFC, was the first SU approved for use in fine turf. Lesco TFC was marketed for tall fescue control in Kentucky bluegrass and other tolerant turfgrass species. This herbicide also controlled many other weeds. However, use of this product was never widely adopted. Shortly thereafter, The O.M. Scotts Company brought metsulfuron to the market under the trade name Scotts DMC Weed Control. Scotts dropped the product after a short time and metsulfuron disappeared from the turfgrass for several years. However, metsulfuron had proven to be an effective, broad spectrum herbicide for which bermudagrass and St. Augustinegrass have excellent tolerance. Metsulfuron controls several problem weeds including prostrate spurge, wild garlic and bahiagrass. In addition, metsulfuron proved to be a useful tool for the transition of ryegrass in overseeded bermudagrass. As a result, metsulfuron developed a following which led to use widespread use of Escort, a metsulfuron product labeled for industrial applications, on highly maintained bermudagrass turf throughout the south. Sulfometuron was developed around the same time as metsulfuron and sold under the trade name Oust. Due to injury on fine turf, use of Oust has been confined to roadside and industrial sites, primarily for bermudagrass release on right-of-ways. Around 2000, metsulfuron and chlorsulfuron were returned to the turfgrass market by Riverdale as Manor and Corsair. Halosulfuron (Manage, SedgeHammer) was the next SU to appear in turfgrass weed control. Monsanto began trials in 1988 and the herbicide was approved for use in turfgrass in the mid 1990s. Halosulfuron, now being marketed by Gowan, is a sedge control herbicide that is unique in that it is safe to use on almost all turfgrasses. Rimsulfuron, trade name TranXit, was the next SU to be introduced into turfgrass use around 2000. The primary target weed was annual bluegrass. However, rimsulfuron has also been shown to be effective on other cool season grasses. TranXit brought the problem of movement of SU herbicides onto sensitive sites such as bentgrass greens to the attention of the turfgrass industry. Griffin introduced TranXit but it is now part of the DuPont portfolio. The period from about 2000 to the present has seen the most rapid increase in the number of SU herbicides being used in turfgrass and consequently the amount of research being conducted. Trifloxysulfuron (Monument), foramsulfuron (Revolver), and sulfosulfuron (Certainty) were all labeled for use in rapid succession. Certainty, Monument and Revovler have demonstrated usefulness for control of several cool season grasses. Monument, developed by Syngenta, is also effective for control of sedges and several broadleaf weeds. Revolver, a Bayer product, is active on goosegrass and shows promise for dallisgrass control. Certainty, from Monsanto, controls johnsongrass and sedges. Flazasulfuron, an ISK Biotech SU, was in university trials in the mid 1990s and then dropped out of sight. It reappeared in 2001 and is now on track for approval as a turfgrass herbicide under the trade name (Katana). Katana will be used for control of cool season grasses, especially tall fescue, and certain sedges and broadleaf weeds." |
