| Abstract/Contents: | "Gray leaf spot (GLS) is one of the most devastating turfgrass diseases in the northeast and mid-atlantic region. The disease, incited by Pyricularia grisea affects many turfgrass species including St. Augustinegrass, perennial ryegrass (PRG) and tall fescue (TF). Growth chamber and field studies were conducted from 1997 to 1999 to determine the impact of nitrogen (N) rate (0, 0.7, 1.4, and 2.7 kg N/90 m2), cutting height (1.3, 1.9, 3.8, 6.3 and 8.9 cm), and clipping removal on the incidence and severity of GLS. In 1997 disease decreased with increasing N, whereas in 1998 and 1999 disease increased with increasing N (99% and 100% increase respectively). For all three years, turf mowed at 1.3, 1.9, and 3.8 cm sustained significantly less foliar injury than turf maintained at 6.3 and 8.9 cm. Removal of clippings reduced disease up to 41% in 1997 for TF, but clipping removal had little effect on disease severity for PRG throughout the study." |
