Abstract/Contents:"The field experiment was conducted on a perennial ryegrass fairway that was maintained according to normal or routine mowing (0.50-in. height with a reel mower), fertilization, irrigation, and other cultural practices typically employed at the golf course. Soil pH was 6.2 with 5.4% organic matter on this native soil site. All treatments were applied with a 35 psi CO2-pressurized back-pack sprayer calibrated to deliver 1.0 gal water per 1000 sq ft from two 8005 flat-fan nozzles spaced 18-in. apart. Individual plots measured 3 ft by 5 ft, and were arranged as a randomized complete block design with three replications. Product treatments, product application rates, and application calendar dates are listed in the table. Pythium blight was visually estimated as percent plot area covered with active mycelium and foliar turf injury due to Pythium blight. All data were subjected to analysis of variance and treatment means were compared by Fisher's protected least significant difference test at P = 0.05 and by preplanned orthogonal contrasts. The experiment was initiated on 27 May, and no disease symptoms were present at that time. Pythium blight activity was observed in early Aug, and the experiment was concluded during the second week of Aug due to severe Pythium blight activity and turfgrass injury. Due to the data variability from this natural infestation of foliar Pythium blight, all treatments were compared to Signature fungicide which is commonly used for preventive control of the disease in turf at this golf course and many other golf courses in the region. More active mycelium was observed in plots treated with Banner Maxx or untreated plots versus Signature on 2 August, and more turf injury was observed in untreated plots versus Signature on 18 Aug. Overall, plots treated with plant protection products listed in the table below exhibited statistically similar levels of Pythium blight versus plots treated with Signature."
