| Abstract/Contents: | "Sand topdresing is a common practice of putting green turf to minimize thatch accumulation, smooth the surface and modify soil. However, wounding and abrasion of host tissue associated with this practice is suspected to enhance anthracnose (caused by Colletotrichum cereale Manns sensu lato Crouch, Clarke, and Hillman). This study evaluated topdressing incorporation method (none, vibratory rolling, soft bristled brush and stiff bristled brush) and sand shape (none, round and sub-angular) for effects on athracnose severity in 2006 and 2007. A split-plot design with incorporation method as the main plot factor and sand shape as the subplot factor was used on a 5-yr-old annual bluegrass (Poa annua L.) turf mowed at 3.2 mm. Topdressing was applied at 0.3 L m-2 every 14 d from 27 June to 5 Sept. 2006 and 14 May to 24 Sept. 2007, respectively. Disease severity was measured as the percent turf area infested using a line-intercept grid count method. The sand shape main effect was the only significant source of variation in both years. Both sand shapes initially increased disease severity 4 to 14% compared to non-topdressed turf in July 2006; whereas neither sand shape increased severity compared to non-topdressed turf in July 2007. Sub-angular and round sands reduced anthracnose 8 to 29% and 7 to 29% respectively, compared to non-topdressed turf during August to September of 2006 and 2007. Anthracnose was less severe in plots topdressed with sub-angular sand than round sand in July 2006 and July through September 2007. The topdressing incorporation methods did not affect anthracnose severity and cumulative sand topdressing reduced disease severity particularly with sub-angular shaped sand. These results support other research recently conducted by the authors indicating that subtle wounding or bruising associated with routine topdressing is not as significant factor affecting anthracnose severity." |
