Abstract/Contents:"Winterkill remains a constant concern for golf courses managing warm-season grasses in the transition zone, especially on ultradwarf bermudagrass (Cynodon dactylon ├Ś C. transvaalensis) putting greens. The use of protective covers is an essential management strategy employed to prevent winterkill on putting greens. Unfortunately, golf courses in the northern transition zone have still experienced detrimental winterkill under protective covers. An observation made on putting greens that experienced winterkill underneath protective covers is a rippled appearance and enhanced survival in the stitched seams, suggesting the presence of additional air space enhances survival. The objective of this two-year field trial was to improve upon current cover strategies with the inclusion of air gaps underneath protective covers. The trial was conducted on a USGA putting green established with four replications of 'TifEagle', 'MiniVerde', and 'Champion' ultradwarf bermudagrass. Five cover treatments were applied in a strip plot design across all cultivars. Three air gap materials, composed of straw, batting fabric, or drainage pipe, were placed underneath protective covers and compared to a cover alone and an uncovered control. Soil temperature was continuously monitored at a 2.5 cm depth throughout the trial, and spring green-up was assessed using digital image analysis and visual quality ratings. The winter of 2019-20 was mild for the region and minimal winterkill was observed, although 'Champion' and the uncovered control had delayed spring green-up compared to other treatments. In 2020-21, all uncovered controls experienced widespread winterkill, regardless of cultivar. The straw and batting air gap treatments provided significantly warmer soil temperature on multiple rating dates in both years of the trial. However, the use of air gaps did not enhance spring green-up or winter protection of ultradwarf bermudagrass during either year of the trial compared to covers alone."
