| Abstract/Contents: | "St. Augustinegrass (Stenotaphrum secundatum), a common lawn grass in the southeastern and gulfcoastal United States, is sensitive to some common postemergence herbicides. Recognition, trifloxysulfuron + metcamifen, is a safened formulation of trifloxysulfuron for use in St. Augustinegrass. Field studies were conducted to evaluate the efficacy and safety of Recognition alone and in combination with other herbicides for control of dollarweed (Hydrocotyle spp.), dallisgrass (Paspalum dilatatum), and common bermudagrass (Cynodon dactylon) and safety in St. Augustinegrass. Commercial standards were included in each trial for comparison. Initial applications were made on 8 Aug. 2022, with a follow up application made in the dallisgrass and bermudagrass studies on 6 Sep. 2022. Statistical analysis was performed in RStudio 4.1.1 using the agricolae package. Means were separated using the Student-Newman-Keuls method. Eight weeks after application, over 90% dollarweed control was achieved with Celsius XTRA (30 g thiencarbazone ha-1, 6.5 g iodosulfuron ha-1, 70 g halosulfuron ha-1), 21 g metsulfuron ha-1, 28 g trifloxysulfuron ha-1 + 21 g metsulfuron ha-1, and 28 g trifloxysulfuron ha-1 + 560 g triclopyr ha-1. Eight weeks after application, 420 g fluazifop ha-1, 28 g trifloxysulfuron ha-1 + 420 g fluazifop ha-1, and 28 g trifloxysulfuron ha-1 + 560 g triclopyr ha-1 + 420 g fluazifop ha-1 provided 100% bermudagrass control. Only 420 g fluazifop ha-1 significantly injured St. Augustinegrass. Twelve weeks after application, over 90% dallisgrass control was achieved with 420 g fluazifop ha-1 and 28 g trifloxysulfuron ha-1 + 420 g fluazifop ha-1. Commercial standards, Tribute Total (22 g thiencarbazone ha-1, 44 g foramsulfuron ha-1, 69 g halosulfuron ha-1) and 3360 g MSMA ha-1, provided 68% and 54% control, respectively. The addition of Recognition to fluazifop minimally decreases weed control, while significantly increasing Augustinegrass safety. Recognition is safe for use in St. Augustinegrass and when combined with other postemergence herbicides provides control of dollarweed, dallisgrass, and common bermudagrass." |
