| Abstract/Contents: | "This trial was conducted at the Lake Wheeler Turfgrass Field Laboratory in Raleigh, NC on 'Tifway' bermudagrass maintained under golf course fairway management conditions. Mowing was performed two times weekly at a height of 0.625-in. with clippings returned and the site was irrigated to prevent drought stress. Fertilizer was applied as 30-6-10 on 6 Jul 09 (1.9 lb N/1000 sq ft). Oxadiazon 2G (3 lb ai/A) was applied on 25 Feb 09 and Prodiamine 65WG (2 lb/A) was applied on 10 Sep 09. Plots were 5 ft x 10 ft and were arranged in a randomized complete block with four replications. Each plot was inoculated in 2005 by removing six cup cutter plugs to a 2-in. depth. Rye grain infested with O. korrae (10 cm3) was placed in the bottom of three of the holes, and 10 cm3 of rye grain infested with O. herpotricha was placed in the bottom of the other three holes before replacing the turf plug. Spring dead spot symptoms first became evident in the spring of 2007. Fungicides in this trial were applied in water equivalent to 5 gal per 1000 sq ft with a motorized backpack sprayer at 40 psi using TeeJet 8008 nozzles. All treatments were initiated on 17 Sep 09 and reapplied at the appropriate interval as indicated in the table. Percent turf area exhibiting spring dead spot symptoms was assessed on 20 Apr 10. Data were subjected to analysis of variance and means separation by Waller-Duncan k-ratio t test (k=100). On 20 Apr 10, spring dead spot incidence was 21.9% in the untreated control plots. All fungicide treatments provided suppression of spring dead spot compared to the untreated control, and no significant differences were detected among the fungicide treatments evaluated." |
