| Abstract/Contents: | "Cold-temperature damage to ultradwarf bermudagrass (UDB; Cynodon transvaalensis ^D#@X Cynodon dactylon) limit successful management of putting greens in colder regions of adaptation. Many golf courses experienced cold-temperature damage to UDB throughout the southeast and Mid-Atlantic during the winter of 2017-2018, causing course closures for complete re-establishment. This research compares alternative recovery methods against traditional eradication and sprigging to re-establish UDB after cold-temperature damage. Treatments were initiated in June when weather conditions became favorable for growth in Richmond VA. Treatments were randomized over four 3.7 m2 plots with three replications across two locations with cold-temperature damage. Treatments (TRT) included 1) eradication of turf with glyphosate followed by sprigging; 2) core aeration followed by application of healthy aeration cores, dragging, and rolling; core aeration followed by application of healthy aeration cores followed by 3) shallow vertical mowing (9.5mm depth) and rolling; and 4) deep vertical mowing (25mm deep) and rolling. Plots were assessed thirteen times over 78d for percent UDB cover (PC) and turfgrass quality (TQ). Data were analyzed as repeated measures and cumulative effects were transformed using area under progress curves. ANOVA revealed no location or treatment × location interaction (P≥0.12); therefore, treatment data were pooled across locations and had significant differences for PC and TQ (P<0.0001). Treatment differences were explained over time using Gompertz 3P non-linear regression (r≥0.88). The inverse prediction model determined that treatment TRT1 reached 95 PC first after 33d and TRT4 was last at 41d. However, TRT2 and TRT3 compared favorably with TRT1 and serve as viable options for recovery without complete re-establishment. Overall TQ was highest in TRT1, with all other treatments comparing favorably to each other. These data suggest that renovation from sprigs will provide the fastest establishment and highest TQ of UDB but that viable options exist without complete eradication." |
