| Abstract/Contents: | "This trial was conducted at the Lake Wheeler Turfgrass Field Lab in Raleigh, NC on Dominant Plus creeping bentgrass maintained under putting green conditions. Mowing was performed five times weekly at a height of 0.140-in. (15 Jan to 28 Mar), 0.180-in. (29 Mar to 8 Jun), and 0.156-in. (after 8 Jun) with clippings collected. The site was irrigated as needed to prevent drought stress. Fertilizer was applied as 15-15-15 on 15 Jan (0.3 lb N/1000 sq ft), 20-0-10 on 19 Jan (0.16 lb N/1000 sq ft), 14-2-14 on 9 Mar (0.25 lb N/1000 sq ft), 18-3-6 on 1 Apr (0.25 lb N/1000 sq ft), 18-9-18 on 15 and 29 Apr (0.33 and 0.75 lb N/1000 sq ft respectively), and 18-3-6 or 14-2-14 (0.1 lb N/1000 sq ft) every other week between 21 May and 17 Aug. Micronutrients were applied as Brexil Multi (1.0 oz/1000 sq ft) on 9 Mar. Insect pests were suppressed with Acelepryn (4.0 fl oz/A) on 22 Apr. Fungicides were applied as Tourney 50WG (0.37 oz/1000 sq ft) on 8 Feb, Emerald 70WG (0.18 oz/1000 sq ft) on 9 Mar, QP Chlorothalonil (3.2 oz/1000 sq ft) on 30 Apr, Subdue MAXX 2ME (1.0 fl oz/1000 sq ft) on 22 Jul, and QP Mefenoxam 2L (1.0 fl oz/1000 sq ft) on 18 Aug. Cascade wetting agent was applied on 2 Apr and 3 May at 8.0 fl oz/1000 sq ft and on 9 Jun, 5 Jul, and 9 Aug at 4.0 fl oz/1000 sq ft. Plots were 3.33 ft x 6 ft and were arranged in a randomized complete block with four replications. Fungicides were applied in water equivalent to 2 gal per 1000 sq ft with a CO2-powered sprayer at 40 psi using a TeeJet 9508E nozzle. All treatments were initiated on 3 Jun and were reapplied at the appropriate intervals as indicated in the table. Turfgrass quality was evaluated on 15 and 29 Jun, 13 and 27 Jul, 10 and 25 Aug, and 8 and 22 Sep, using a 1 to 9 scale (9=best, 5=acceptable) based on color, density, and uniformity. Data were subjected to analysis of variance and means separation by Waller-Duncan k-ratio t-test (k=100). Record breaking temperatures imposed severe stress on creeping bentgrass greens during the summer of 2010. Both programs evaluated in this study failed to maintain acceptable turf quality throughout the season, with the BASF Program providing acceptable quality in the middle of the study and the NCSU Program providing acceptable quality late in the study. The BASF Bentgrass Program improved turf quality compared to the untreated control on 13 and 27 Jul, 10 and 25 Aug, and 8 Sep and provided acceptable turf quality on four of eight rating dates. Acceptable turf quality was provided by this program following applications of Spectro on 1 Jul, Signature + Daconil on 15 Jul, and Insignia on 29 Jul. The NCSU Program significantly improved turf quality on the last four rating dates and was statistically superior to the BASF Program on 8 and 22 Sep. Plots treated with the NCSU Program exhibited the best turf quality following applications of Disarm C + Subdue on 29 Jul, Daconil + Signature on 12 Aug, Disarm C + Signature on 26 Aug, and Signature + Daconil on 9 Sep." |
