| Abstract/Contents: | "Spring dead spot (SDS) is among the most damaging diseases to bermudagrass (Cynodon dactylon) in areas where winter dormancy occurs. Most SDS research efforts have focused on preventative chemical and cultural management strategies for the disease. However, many of the preventative tactics employed have been inconsistent, so management strategies that aid in turfgrass recovery are necessary. This experiment elucidates the most effective cultural management practices to employ to recover from SDS damage in the late spring/summer. A field trial was conducted from 24 May 2019 to 2 August 2019 and repeated the following year from 25 June 2020 to 6 August 2020 on Patriot bermudagrass. The study was a randomized complete block design with four replications. There were six treatments in the study: 1) nontreated control 2) two applications of urea two weeks apart totaling (97.6 kg N ha-1) 3) verticutting 4) solid-tine aerification 5) verticutting + two applications of urea two weeks apart totaling (97.6 kg N ha-1) and 6) solid-tine aerification + two applications of urea two weeks apart totaling (97.6 kg N ha-1). Plots were assessed for percent necrosis either weekly or biweekly throughout the study. Data were analyzed as percent necrosis change relative to initial assessment in order to measure bermudagrass recovery from SDS damage. Data were subjected to ANOVA and means were separated using the students t-test (P < 0.1) in JMP Pro 15. The main effect of cultivation increased (P < 0.07) bermudagrass recovery from SDS damage in both 2019 and 2020 while the main effect of fertility increased bermudagrass recovery only in 2019. Urea, alone, was the most effective treatment for increasing bermudagrass recovery while verticutting, alone, was the least effective. These data suggest that fertilizing with urea, alone, in the late spring/early summer is sufficient to optimize bermudagrass recovery from SDS damage." |
