| Abstract/Contents: | "Fungicides were evaluated for their ability to control gray leaf spot on perennial ryegrass at the Rutgers Turf Research Farm in North Brunswick, NJ. Turf was established 12 May 99 on a Norton loam with a pH of 6.5. Mowing was performed two times weekly at a height of 2.5 in. and clippings were collected. The site was irrigated to prevent drought stress. Fertilizer was applied as 10-10-10 on 12 May (0.5 lb. N/1000 sq ft) and 4 Jun (0.5 lb. N/1000 sq ft), and as 46-0-0 on 25 Jun (1.0 lb N/1000 sq ft) and 26 Jul (0.5 lb. N/1000 sq ft). ProStar 70W was applied to the entire study on 23 Jun (2.0 oz/1000 sq ft), 27 Jul (2.0 oz/1000 sq ft), 30 Aug (2.0 oz/1000 sq ft) and 14 Sep (2.0 oz/1000 sq ft) to prevent brown patch. Weeds were controlled wtih Acclaim Extra 0.57E (0.46 fl oz/1000 sq ft) on 9 Jun, MCPP-2 amine (0.55 fl oz/1000 sq ft) on 1 Jul, and 2,4-D-1 amine (3.67 fl oz/1000 sq ft) plus Banvel-4 amine (0.18 oz/1000 sq ft) on 3 Aug. Plots were 4 ft x 5 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 30 psi using TeeJet 8003E nozzles. Treatments (trt) were initiated on 19 Aug. Fungicides were reapplied at the appropriate intervals as indicated in the table. Percent turf exhibiting foliar symptoms of gray leaf spot was assessed on 15 Sep and 22 Sep. Turf quality was evaluated on 4 Oct using a 1 to 9 scale, where 9=the best turf quality. Data were subjected to analysis of variance and means separation by Waller-Duncan k-ratio t-test (k=100). Natural gray leaf spot infection was first observed on 22 Jul, but did not become evenly distributed throughout the test until 18 Aug. The disease developed rapidly from 18 Aug to 15 Sep, resulting in 85% turf area infected in untreated plots (trt 11). Cleary 3336 50W (trt 1), Heritage 50WG (trt 2), Fore 80W (trt 3), Daconil Ultrex 82.5SDG (trt 4), and Eagle 40W + Fore 80W (trt 6) provided good to excellent disease control throughout the study. Eagle 40W (trt 5), Bayleton 50W (trt 7), and F-155 20W (trt 8-10) did not provide acceptable disease control at the rates tested. Turf quality was closely associated with prior incidence of gray leaf spot (18 Aug - 4 Oct). No phytotoxicity was observed." |
