| Abstract/Contents: | "Dollar spot (caused by Sclerotinia homoeocarpa) is a prevalent disease on golf course turfs throughout the United States. The effect of lightweight rolling on dollar spot incidence of creeping bentgrass (Agrostis stolonifera L. Independence) was assessed in a field study maintained at 12.7 mm on a sandy loam in North Brunswick, NJ. A 2 × 2 factorial arranged in a randomized complete block design with four replications was used to evaluate the time of day [morning (AM) or afternoon (PM)] and frequency (3 or 6 d wk-1) of lightweight rolling during the fall of 2015, spring of 2016 and fall of 2016. Two additional treatments were included in the design: morning removal of dew using an absorbent fabric and an untreated control. Plots rolled in the morning when dew was present had the greatest impact on disease incidence, reported as the area under disease progress curve (AUDPC), reducing AUDPC by 52, 33 and 39% compared to PM rolling during the fall 2015, spring 2016 and fall 2016, respectively. The frequency of rolling interacted with time of day to affect dollar spot incidence on a few observation dates in fall 2015. The interactions suggested that more frequent AM rolling (6 d wk-1) may be more effective at reducing disease incidence compared to less frequent AM rolling (3 d wk-1), whereas rolling frequency did not affect disease with PM rolling. There was no effect of rolling frequency on disease during the spring regardless of the time of day. A time of day by frequency interaction during fall 2016 again suggested that more frequent AM rolling (6d wk-1) reduced disease incidence compared to less frequent AM rolling (3d wk-1); whereas, more frequent PM rolling (6 d wk-1) increased disease incidence compared to less frequent PM rolling (3d wk-1). Removal of dew using an absorbent fabric reduced AUDPC by 74, 53 and 60% during the fall 2015, spring 2016 and fall 2016, respectively, compared to the untreated control. This reduction from dew removal with an absorbent fabric was similar to the disease reduction from AM rolling 6 d wk-1 during fall 2015, spring 2016 and fall 2016. This research will be continued during the spring of 2017." |
