Abstract/Contents: | "Sand topdressing is applied to maintain or enhance playability of the turf surface of putting greens. Anthracnose is a devastating disease of annual bluegrass (ABG; Poa annua) putting green turf, caused by Colletotrichum cereal. The disease is more severe on weakened turf and reputed to be exacerbated by management practices that wound turf. A 2-year field study was initiated in 2007 to evaluate the effects of foot traffic (0 versus 327 footsteps m-2, equivalent to 200 rounds day-1) and sand topdressing (0 and 0.3 liter m-2 every week) on anthracnose severity of ABG mowed at 3.2 mm. Surprisingly, foot traffic reduced anthracnose severity as much as 28%, regardless of sand topdressing, during both years. Although sand topdressing initially increased disease severity (up to 7%) in 2007, continued applications decreased severity by 9% later in August 2007 and again in 2008. The treatment combination of foot traffic 5 days week-1 and weekly sand topdressing resulted in the best turf quality by the end of both seasons. Results indicate that the practice of sand topdressing can be continued even under conditions of intense foot traffic and anthracnose disease development on ABG putting greens." |
