| Abstract/Contents: | "Dollar spot (DS) (Clarireedia spp.) is the most common disease of creeping bentgrass (CBG) (Agrostis stolonifera) golf course fairways. Two methods to suppress DS that are increasingly employed by golf course superintendents include the use of ferrous sulfate (FS) and light-weight rolling (LR). While individual efficacy of each method is documented, their cumulative effects have not been investigated. Therefore, our research objective was to examine the role of FS, LR, and their interaction on DS development on CBG fairways. Field studies were arranged in a 3x2 split-plot, factorial design across four replications on an 'L-93' CBG fairway in Blacksburg, VA and repeated in 2017 and 2018. Main factor of LR was performed 0, 1, or 2 d-1 using a Smithco Tournament Ultra Lite Roller 3 wk-1. Ferrous sulfate was applied biweekly with 0 or 24.4 kg ha-1. Dollar spot infection center counts (IC) and visual turf quality (TQ) assessments were collected weekly and transformed using area under progress curves to determine cumulative effects. Interactions of LR, FS, and year were not significant (Pā„0.10) and data were, therefore, pooled across years. Application of FS reduced DS IC by 70% and increased TQ across all FR treatments (P<0.0001). Dollar spot was suppressed by 61% with plots rolled 2 d-1 but not suppressed with 1 d-1 LR relative to non-rolled plots (P=0.0034). LR did not impact overall TQ in these studies (P=0.68). Dollar spot was suppressed equally with LR 2 d-1 and unrolled FS applications (P<0.0001). There were no negative interactions between FS applications and LR, however, our data does not suggest that their interaction enhances DS suppression or TQ in this study." |
