Abstract/Contents:"The field experiment was conducted on a perennial ryegrass fairway (Philadelphia Country Club, Gladwyne, PA) maintained at a 0.450-in. mowing height with a reel mower and clippings not removed. Soil pH was 6.7 with 4.1% organic matter at this native soil site. All treatments were applied with a CO2-powered backpack sprayer pressured to 40 psi and calibrated to deliver 4 gal water-carrier per 1,000 sq ft from one XR TeeJet 8006E nozzle. Individual plots measured 3 ft x 5 ft, and treatments were arranged as a randomized complete block design with three replications. Product treatments, application rates, and application calendar dates are listed in the table. Fairy ring was evaluated as a combination of both type I and II symptoms present in the plots, therefore total symptoms were estimated on a percent plot area basis on a 0 to 100% scale, where 0 = no disease and 100 = entire plot area affected. All data were subjected to analysis of variance with treatment means compared by Fisher's protected least significance difference test at P = 0.05. The experiment was initiated on 25 May with no fairy ring symptoms present at this fairway site with a history of severe fairy ring. In Jul, the hot and humid weather (i.e., heat stress) combined with low rainfall (i.e., dry soil conditions) provided additional turf stress, and therefore both type I and II fairy ring symptoms were visibly evident and more noticeable during Jul through mid-Aug. The fairy ring species was identified as Agaricus campestris based on the visual appearance of basidiocarps within the test area. On 12 Jul, or three weeks after the last treatment, fairy ring symptoms were minimal (i.e., < 5% plot area affected) in all fungicide and/or soil surfactant treated-plots compared to the untreated plots. On 24 Jul, or five weeks after the last treatment, best residual suppression of fairy ring symptoms (i.e., < 5% plot area affected) were observed in plots treated with Prostar + Revolution (tank-mix), Revolution FB Insignia, or Surfside FB Insignia. By mid-Aug or eight weeks after the last treatment, fairy ring symptoms ranged from 15 to 32% plot area affected in all treated plots, and 38% in the untreated plots. On 14 Aug, plots treated with Prostar + Revolution, Insignia alone, or Revolution FB Insignia exhibited a reduction in fairy ring symptoms statistically lower than observed in untreated plots. By mid-Sep, fairy ring symptoms subsided in the test area and affected turf areas began to recover."
