USGA Summary Points:Aeration treatments were conducted in August of 2020. Cold tolerance/spring green up data were collected in spring of 2019, aeration recovery data were collected following aeration and TruFirm and volumetric water data were collected monthly during the growing season. A second year of trinexapac-ethyl treatments were made during the fall/winter of 2019/20 on four different ultradwarf putting greens (G12 and TifEagle) with four replications at each location. Champion ultradwarf bermudagrass plugs were planted in the spring of 2020 in 6 pots with 80/20 greens mix over pea gravel to simulate USGA spec putting greens. Pots were maintained in temperature-regulated greenhouse to mimic summer conditions. Pots received urea (0.25#N/1000ft2), trinexapac-ethyl (Primo Maxx 3 fl. oz/A), and chlorothalonil (Daconil Weatherstik, 3.6 fl. oz/1000ft2) every two weeks in the greenhouse. Pots were transferred into the field to acclimate in July of 2020, where pots were separated into two treatments; 1) trinexapac-ethyl (3oz/Acre every two weeks from July 23-October 8) and 2) nontreated control. Twenty-four randomized UDB pots underwent cold temperature acclimation to mimic fall conditions from July 23, October 8, 2020. After undergoing fall temperature simulation, pots were treated to 15°F for 4, 6, 8, and 10 hours to mimic cold temperature exposure. Zero hours represented no damage and 14 hours represented lethal damage. After cold-temperature exposure In early 2020 (Pre-Covid 19), Dr. Zhang and Jordan Booth evaluated a series of testing methods for rapid assessment of winter injury of bermudagrass using existing and improved methods.
