| Abstract/Contents: | "The experiment was conducted at the Valentine Turfgrass Research Center, University Park, PA, on a mixed stand of colonial bentgrass and annual bluegrass maintained under golf course fairway management conditions, and mowed three times per week at a height of 0.5-in. The soil was Hagerstown silt loam with a pH of 6.8. Treatment plots, 3 ft x 6 ft, were arranged in a randomized complete block design with three replications. Applications were made with a CO2-powered sprayer, using a TeeJet 11008E nozzle, at 40 psi, in water equivalent to 2 gal per 1000 sq ft. The treatments were applied on 27 May, 11 and 24 Jun, 8 and 22 Jul, and 4 Aug on a 14-day interval, and 27 May, 17 Jun, 8 and 28 Jul on a 21-day interval. Dollar spot incidence (infection centers per plot) was assessed on 9, 16, and 23 Jun, and 1, 7, and 14 Jul. Data were subjected to analysis of variance and multiple comparisons of the means were made using the Waller-Duncan k-ratio test (P<=0.05). Environmental conditions were conducive for dollar spot development early in the season. Disease development was moderately severe in the early part of the experiment, and disease incidence gradually increased to moderately high levels during the latter course of the experiment. In untreated control plots mean disease incidence was 8.3 on 9 Jun, increased to 25 by 1 Jul, and by 14 Jul increased to 44 infection centers per plot. Most fungicides provided excellent to good control of dollar spot. Products providing the most satisfactory control were Banner MAXX, Honor, Emerald, Insignia, Disarm M, and tank-mixtures of Civitas + Banner MAXX + Daconil Ultrex. No phytotoxicity was observed in any of the treatment plots during the course of the experiment." |
