Abstract/Contents:"The field experiment was conducted on a perennial ryegrass fairway (Philadelphia Country Club, Gladwyne, PA) mowed at 0.450-in. with a reel mower and clippings not removed. Soil pH was 6.4 with 4.5% organic matter at this native soil site. All treatments were applied with a CO2-powered backpack sprayer pressured calibrated to deliver 4 gal watercarrier per 1,000 sq ft at 40 psi from one XR TeeJet 8006E nozzle. Individual plots measured 3ft 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. A combination of both type I and II fairy ring symptoms were present at this test site, therefore total symptoms in each plot were estimated 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.Jet 8006E nozzle. The test site has a history of fairy ring symptoms typically appearing during mid-Jun and persisting through Aug. Therefore, the experiment was initiated preventively on 25 May with no fairy ring symptoms present. Both type I and II fairy ring symptoms were first observed during late Jun/early Jul in association with hot and humid weather combined with dry soil conditions. Several basidiocarps found within the test site were identified as Agaricus campestris. On 12 Jul, or 22 days after the last treatment, fairy ring symptoms ranged from 0 to 9% plot area affected in all fungicide, fungicide + soil surfactant (i.e., Revolution) tank-mixes, or soil surfactant alone-treated plots compared to 19% plot area affected in untreated plots. Although not statistically significant, a consistent trend was observed on 24 Jul (35 days after the last treatment) and 14 Aug (56 days after last treatment) with a noticeable reduction in fairy ring symptoms in all fungicide + soil surfactanttreated plots compared to fungicide alone-treated plots. By mid-Sep, fairy ring symptoms dissipated in the test area and affected turf within the plots began to recover."
