Abstract/Contents:Presents a study conducted to "determine the effectiveness of spring and fall fungicide applications for reduction of spring dead spot incidence and severity" and "to determine the effect of organic fertilizer for the reduction of spring dead spot incidence and severity and overall improvement of turf quality." Details methods and materials used in the study, stating that "this study was initiated in the spring of 2007 in [a] Tifway bermudagrass fairway...Spring dead spot symptoms were observed throughout the study area in the spring of 2007...Treatments plots (15 x 10 ft. [feet]) are arranged in a randomized complete block design with a split-plot arrangement of treatments and replicated four times." Reports that "the occurrence of O. korrae was greatest in Tifway bermudagrass roots in spring transition (9.4%) compared to summer (4.6%) and fall (3.1%) transition growth periods in 2005 and 2006"; "Fenarimol and other standard fungicides labeled for spring dead spot control are applied to symptomatic Tifway bermudagrass fairway in the spring and fall"; and "an organic or inorganic nitrogen source is applied concurrently with fungicides to identify a fungicide/nitrogen source combination that results in reduced spring dead spot incidence and severity."
