| Abstract/Contents: | "Evaluation of fungicides for control of fusarium patch, 1997: Fungicides were evaluated for their ability to control Fusarium patch on a putting green at the Peace Pipe Country Club in Denville, NJ. The test area was mowed at a height of 0.156 in. seven times per week with clippings collected. The turf was irrigated to avoid drought stress. Fertilizer was applied as 18-5-10 on 7 Sep 1996 (1 lb N/1000 sq ft) and 12 Apr 1997 (0.5 ob N/1000 sq ft). Turcam 2.5G (2 lb/1000 sq ft) was applied on 10 Aug 1996 for control of insect pests, and Bayleton 25DF (2 oz/1000 sq ft) was applied on 2 Sep 1996 for preventative dollar spot control. Plots were 3 ft x 9 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 or by hand using a shaker jar. Treatments (trt) were first applied on 27 Nov 1996. Fungicides requiring a spring application were reapplied on 7 Feb 1997 as indicated in the table. The number of Fusarium patch infection centers per plot was assessed on 19 Mar. Average patch diameter was 3 in. Winter injury in the form of tip burn was also rated on 19 Mar using a 0 to 5 scale, 0=no tip burn and 5=all foliage exhibiting tip burn. Data were subjected to analysis of variance and means separation by Duncan's New Multiple Range Test (p=0.05). No extended periods of snow were experienced during this trial. However, significant disease development occurred in absence of snow cover during cool, wet periods in late Feb and early Mar. Excellent control of Fusarium patch was provided by most treatments in this trial. In general, fall applications of several fungicides (trt 11-14, 19, 20, 22, 26-31) were as effective as treatments with fall and spring, applications, even though disease development primarily occurred in the spring. A significant amount of disease was observed in plots treated with the 0.6 oz rate of Eagle 40W (trt 1), Eagle 40W + Chipco 26019 50WG (trt 6), Lynx 25DF (trt 15), and Sentinel 40WG (trt 21). Winter injury was more severe in plots treated with Eagle 40W + Fore 80W (trt 4, 5) and Sentinel 40WG + Rizolex 75W (trt 23) when compared to untreated turf." |
