| Abstract/Contents: | "Fungicides were applied on 13 Jun when disease symptoms became evident in a spring-seeded (27 Mar) stand. Soil was a silt loam with a pH of 5.9 and O.M. 3.7%. Fungicides were applied with a CO2 pressurized sprayer at 38 psi in 2.5 gal/1000 sq ft. Plots were 5 ft x 5 ft and were arranged in a randomized complete block with four replications. Percent plot area diseased was visually estimated on a 0 to 100% scale. Brown patch ratings exceeding 5.0% of plot area diseased would be considered unacceptable under golf course fairway conditions. Disease activity was moderate when fungicides were applied but intensified to severe by 11 Jul. Data collected 26 Jun showed that all fungicide treatments had provided good to excellent brown patch control. Acceptable levels of residual browm patch control, assessed 11 Jul, were provided by Daconil 2787, Lesco 0585, Bromasan (18 fl oz/ 1000 sq ft), and Spotless (1.6 oz/1000 sq ft). There was, however, no statistical difference in disease control by Spotless (0.8 oz/1000 sq ft) and the aforementioned fungicide treatments." |
