Abstract/Contents:"Sand topdressing on putting green turf enhances surface aesthetics and playability. Anthracnose, caused by Colletotrichum cereale Manns, is a disease of annual bluegrass [Poa annua L. f. reptans (Hausskn) T. Koyama], which is more severe on stressed turf and was thought to be enhanced by sand topdressing and foot traffic. A two year field study was initiated in 2007 to evaluate the effect of foot traffic and sand topdressing on anthracnose severity in North Brunswick, NJ. A split-plot design with for traffic [none and 392 footsteps m-2 wk-1) as the subplot factor was used on an annual bluegrass putting green established on a Nixon sand loam and maintained at a 3.2 mm cutting height. Foot traffic was initiated 14 June 2007 and 15 May through 29 August 2008. Nitrogen was applied bi-weekly at 4.9 kg ha-1 resulting in a total of 29.3 kg ha-1 during the time treatments were applied. Foot traffic was applied after morning mowing as straight line passes (5 d wk-1) by students wearing golf shoes equipped with soft spikes. Anthracnose was rated using a line-intersect grid counting method. Surprisingly, foot traffic reduced anthracnose severity as much as 27% regardless of the level of sand topdressing in both years. Sand topdressing resulted in a subtle increase in disease severity during June and July 2007. However, disease severity decreased by August as topdressing continued in 2007. Disease severity was either not affected or reduced by topdressing during 2008. Interactions between treatments occurred three times during the two year study. The interaction in 2007 (two dates) indicated that the reduction in disease severity caused by topdressing began sooner in plots that also received foot traffic. In 2008 (one date), the reduction in disease severity resulting from topdressing was only apparent in plots that received regular foot traffic. Although visual symptoms of wear stress were evident in foot traffic plots, the treatment combination of foot traffic (5 d wk-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 should not be terminated, even under conditions of intense foot traffic, when anthracnose develops on annual bluegrass putting greens."
