| Abstract/Contents: | "Athracnose, caused by Colletotrichum cereale Manns, is a highly destructive disease of annual bluegrass [Poa annua L. f. reptans (Hausskn) T. Koyama] turf. Previous work has shown that both granular- and liquid-N fertilization play an important role in anthracnose suppression, however the potential interactive effect of both factors on disease severity has not been reported. The objectives of this study were i) to evaluate the impact of late- or early- season granular-N fertilization rate on anthracnose severity and ii) to determine whether late- or early-season granular-N fertilization alters the effect of frequent low rate soluble- N fertilization on anthracnose. The field study conducted on annual bluegrass turf maintained at 3.2 mm was initiated in 2008 in North Brunswick, NJ. The experiment was arranged as a randomized complete block with three replications. Treatments were arranged as a 2 x 3 x 4 factorial with primary season of granular-N fertilization (2/3 of total N applied in the fall or spring), annual granular-N rate (73, 146 and 219 kg ha1 ), and frequency of summer soluble-N (4.6 kg ha1 of soluble-N applied every 0, 1, 2 or 4 weeks from mid-May through August 2009 and 2010) as main factors. Summer soluble-N applied every week (18.3 kg N ha1 month 1 ) had the greatest reduction in anthracnose severity compared to other summer frequencies. Granular-N fertilization applied primarily in the spring reduced disease severity compared to autumn based granular-N fertilization on all but two rating dates. The rate of granular-N fertiliza tion also affected disease severity; N applied at an annual rate of 219 kg N ha1 had less disease than plots that received lower N rates. Interaction between season and granular-N rate indicate autumn based fertilization at 219 kg N ha1 annually was needed to reduce disease severity; whereas, the spring granular program reduced disease severity at 146 kg N ha1 annually." |
