| Abstract/Contents: | "Fungicides were applied with a CO² pressurized (35 psi) sprayer equipped with a flat-fan (8010) nozzle, and calibrated to deliver 2.5 gal water per 1000ft₂. Dates of application are noted in the data table. Soil was a Chillum silt loam with a pH of 6.2 and 2.7% OM. Turf was mowed to a height of 0.75 in., fertilized with 3.0 lb N/1000ft₂/yr, and irrigated to prevent drought stress. Plots were 5 x 5 ft, and were arranged in a randomized complete block with four replicates. Percent of plot area blighted was assessed visually on a linear 0 to 100% scale where 0 = no blight and 100 = entire plot area blighted. Brown patch and dollar spot ratings exceeding 5 and 0.5%, respectively would be considered unacceptable disease control for a golf course fairway. Brown patch pressure was severe throughout most of the study. Lynx provided generally good control until 19 Jul (i.e., 7 days after last applied). This loss of control coincided with intense environmental conditions conducive to a brown patch epidemic in mid-Jul. Sentinel (0.25 and 0.33 oz) and ProStar provided equivalent, and acceptable brown patch control, when applied twice on a 28-day interval. Sentinel (0.25 or 0.33 oz) applied once provided acceptable brown patch control until 12 Ju (i.e., about 28 days after treatment), but thereafter blighting became severe in these plots. Sentinel and Lynx provided excellent dollar spot control. ProStar-treated plots were more severely blighted by dollar spot than untreated plots." Data collected from this study is presented in table form. |
