| Abstract/Contents: | "The research was conducted at the Turfgrass America sod farm in Apollo Beach, FL. The experimental site was a stand of 'SeaIsle 1' seashore paspalum. Plots were maintained by the Turfgrass America sod farm staff with standard practices of mowing, insecticide application, herbicide application, and flood irrigation when appropriate. The plot area did not receive nitrogen fertilizer during the study. On 8 Apr fungicide treatments were initiated using a CO2 backpack sprayer, calibrated to deliver 2 gal/1000 sq ft per treatment through two Teejet (8003) nozzles. Treatments were reapplied on 29 Apr, 6 May, and 20 May. Treatments were randomized within four replications of 3.3 ft by 6.6 ft plots. Disease was allowed to develop from natural inoculum. A disease sample was collected, and the dollar spot pathogen was isolated for diagnostic confirmation. Disease severity was recorded by counting the number of infection centers per plot. Data shown below are average number of infection centers per plot for each treatment. All untransformed data were subjected to statistical analysis, and significant differences among means were identified. Applications began curatively on 8 Apr. April was cool (average temperature for April at test site was 67°F) and favored disease development over turfgrass growth and recovery. When warmer temperatures occurred later in the trial (average temperature for May was 75°F), the turfgrass began to recover with the fungicide applications. All fungicide products and programs tested provided excellent control of dollar spot on seashore paspalum during the trial. After the first week of June, the turfgrass in the control plots recovered from the dollar spot disease. No additional dollar spot symptoms were observed. No growth regulator effects or phytotoxicity were observed throughout the trial." |
