| Abstract/Contents: | "Dollar spot is one of the most intensively managed diseases on turf. The objective of this study is to further our understanding of the role of IPM in reducing inorganic fertilizer and pesticides applications to control dollar spot. A creeping bentgrass field plot was established and monitored. Nitrogen fertility and compost topdressing significantly influenced turfgrass quality, foliar nitrogen content, and clipping yield. Additional differences in foliar elemental concentrations were also observed. Foliar nitrogen concentrations were negatively correlated with desease severity irrespective of nitrogen source. Fungicide was reduced 60% in the IPM program when compared to a label-rate application program. Compost topdressings reduced the need for inorganic fertilizers in the first 6-10 weeks post-application. A study is underway to determine the long-term impact of compost-topdressings on plant nutrition, disease and insect suppression, and soil tilth." |
