| Abstract/Contents: | "The test was conducted at The Ohio State University Turfgrass Research Center, Columbus, OH on a stand of creeping bentgrass established in 1997. Mowing height was 0.17-in., clippings removed and the area was irrigated as needed. The condition of the sward was good with fair color, minimal thatch and good density. No fertilizer was applied before or during the evaluation. The soil was Crosby B silt loam, pH 7.3. Individual plots measured 3 ft x 5 ft, with 1 ft alleys between plots, and 2 ft between blocks, and were arranged in a randomized complete block design with three replications. Treatments were applied with a hand-held, CO2-powered boom sprayer using 6503 TeeJet nozzles at a pressure of 40 psi, (water equivalent to 2.0 gal water/1000 sq ft) for all treatments. All treatments were started on 15 Jun. Percent of plot area blighted was assessed visually on a linear 0 to 100% scale where 0 = no blight and 100 = entire plot blighted. Analysis of variance was performed with least significant difference at the P=0.05 level. The average high and low air temperatures (°F) and rainfall (in.) for each month respectively were: May 76.8, 55.7 and 7.1; Jun 79.9, 58.8 and 3.5; Jul 81.2, 62.8 and 11.3; and Aug 80.9, 59.9 and 7.6. Environmental conditions were favorable for brown patch development from natural inoculum in mid-Jun to early-Aug with moderate levels of disease symptoms expressed early in the evaluations period and severe symptoms by late Jul. Insignia and Spectro treatments provided complete control at 8 days after the initial application and throughout the evaluation. The Velocity treatment showed moderate phytotoxicity to the turf." |
