Abstract/Contents: | "Preventive applications of DMI fungicides provide control of several soilborne turfgrass diseases on golf putting greens. The objectives of this twoyear field study were to determine the impact of these watered-in applications on foliar diseases, and evaluate the impact of application timing of paclobutrazol, a plant growth regulator, on disease severity. Plots were 1.5 m × 1.5 m, and arranged in a randomized complete block with four replications. The experimental design was a split-plot with creeping bentgrass cultivar ('Penncross' and 'Penn A-4') as the main plot, and fungicide and paclobutrazol application as subplots. Triadimefon (0.16 g m-2), tebuconazole (0.08 g m-2), metconazole (0.04 g m-2), and triticonazole (0.06 g m-2), were applied twice in late April and May. Paclobutrazol (0.03 g m-2) was applied alone, in a tank-mix with the fungicide application, 7 d, or 14 d after the fungicide application. Fungicide and fungicide + paclobutrazol tank-mix applications were immediately watered-in with 5 mm of irrigation. Dollar spot severity was significantly lower in fungicide-treated plots than untreated plots and plots treated with paclobutrazol alone. Triadimefon-treated plots had lower AUDPC values than other fungicide treatments. Short-lived phytotoxicity (bronzing) was observed in plots treated with both paclobutrazol and fungicide. Spring preventive fungicide applications targeted at soilborne disease control also provided control of a foliar disease." |
