| Abstract/Contents: | "Bermudagrass turf quality is commonly reduced in the transition zone by Ophiosphaerella herpotricha, a root-infecting fungus that causes spring dead spot (SDS). Fungicides applied in autumn typically result in poor to moderate disease suppression. Earlier research has indicated that some cultural practices, including core aerification or fertilization with soil acidifying nitrogen fertilizers, may suppress SDS. Our objective was to evaluate several treatment combinations for reducing disease severity. Treatments were arranged in a split-plot design, with whole plots being aerification + verticutting, or no cultivation. Subplots with whole plots consisted of a factorial arrangement of azoxystrobin (one September application of at 0.6 kg·ha⁻¹), trinexapac-ethyl (three summer applications at 6.1 kg·ha⁻¹), and ammonium sulfate (three summer applications with N at 49 kg·ha⁻¹). After 1 year of treatment, spring turf quality was improved in all treatments that included trinexapac-ethyl. Diseased area was reduced from 34% to 21% in plots receiving azoxystrobin + trinexapac-ethyl." |
