| Abstract/Contents: | "Hybrid bermudagrass (Cynodon transvaalensis Burtt-Davey x C. dactylon (L.) Pers.) often requires fall overseeding with perennial ryegrass (Lolium perenne L.) to sustain acceptable quality through the winter and spring. However, during the ensuing spring, ryegrass aggressively competes with the bermudagrass for resources, which complicates spring transition, impairs the bermudagrass base, and results in unacceptable turf quality. Field studies were conducted in Clemson, SC from mid-April to July 2006 and 2007 utilizing two mowing heights (1.2 and 2.5 cm), two nitrogen rates (18 and 36 kg N ha-1 week-1), three trifloxysulfuron rates (0.005 and 0.017 kg ai ha-1) and three application dates (mid-April, mid-May, and untreated) to determine the best treatment(s) to optimize spring transition and provide continuous acceptable turf quality. Turf quality, percent ryegrass/bermudagrass, shoot/root dry weight, and bermudagrass shoot counts were measured at various times following treatments. Both years trifloxysulfuron affected all parameters except 2006 root dry weight. In 2006, all treatments except untreated and 2.5 cm low April trifloxysulfuron treatments experienced unacceptable quality for a minimum of 2 weeks. However, both 2.5 cm low April trifloxysulfuron and control treatments possessed unacceptable ryegrass percentages at studies end, 30 June. In 2007, untreated and 1.2 cm height and low May trifloxysulfuron treatments at both fertility levels maintained acceptable (>7) turf quality for the duration of the study. All trifloxysulfuron treatments had 0% ryegrass and 100% bermudagrass coverage at studies end, 1 July. In Clemson, SC, best overall transition followed 1.2 cm mowing height, 36 kg N ha-1 week-1 and 0.005 kg ai ha-1 mid-May trifloxysulfuron treatments." |
