| Abstract/Contents: | "The study was conducted at the Valentine Turfgrass Research Center, University Park, PA, on a stand of 'SR-7150' colonial bentgrass mowed three times per week at 0.5-in, with a Hagerstown silt loam soil with a pH of 6.9. Plots were 3 ft x 6 ft and arranged in a double-stacked randomized complete block design. Applications were made with a CO2-powered sprayer at 40 psi using a TeeJet 11008E nozzle in water equivalent to 2 gal per 1,000 sq ft unless otherwise noted. The treatments were applied on 18 Jun, 3, 18, and 31 Jul, and 16 Aug on a 14-day interval, and 11 and 31 Jul on a 21-day interval. The experiment area was fertilized with 0.30 lb N/1000 sq ft with urea (46-0-0) on 13 Jun and 0.75 lb N/1000 sq ft with NXPro (29-0-10) on 18 Jun. Bifenthrin was applied on 25 Jul at 0.25 oz/1000 sq ft of product for treatment of black cutworms. Brown patch severity (Index 0-10; 0=turf asymptomatic; 1=1-10% turf symptomatic; 10=>90% turf area symptomatic) was assessed on 8, 16, 23, and 30 Jul, and 10, 17 and 30 Aug. Data were subjected to analysis of variance and multiple comparisons of the mean values were made using the Waller-Duncan k-ratio t-test (k=100). Brown patch symptoms developed in late June, and disease remained persistent into August. Data in the table were sorted by the figures of 30 Jul, when the mean severity rating in the control plot reached 6.7. Several treatments, including Insignia SC, Honor, Prostar, Affirm, Heritage, Velista and tank-mixes containing Velista, Heritage TL, a rotation of half rates of Daconil Ultrex, Civitas, and strobilurin fungicides, Daconil Action, Encartis, and Chipco 26GT provided excellent brown patch control." |
