Wheat cultivars PBW-343, PBW-550 and Agra local were used for testing seven fungicides viz., Propiconazole (Tilt 25EC), Tebuconazole (Folicur 250EC), Triadimefon (Bayleton 25%WP), Tebuconazole DS (Raxil 2%WP), Azoxystrobin 23% (Quadris 25SC) at 0.1 per cent while as Mancozeb (Dithane M-45) and Mancozeb + Carbendazim (Saaf) at 0.2 per cent concentration, respectively and three sowing dates viz., 15 Nov, 30 Nov. and 15 Dec. at University farm Chatha SKUAST-K during Rabi 2009-10. Sowing date (15th Nov.) significantly reduced the disease severity (36.42%) followed by late (30 Nov.) and very late sowing (15 Dec.), respectively. Different cultivars showed different levels of infection and yield at different sowing dates. Under field conditions, Raxil (0.1%) as seed treatment and Quadris (foliar spray @ 0.1%) were found most effective against brown rust followed by Raxil (ST) + Folicur (FS), and Raxil (ST) + Tilt (FS), respectively, at same concentration. Foliar application of chemicals singly or along with Raxil (ST) exhibited significant increase in yield of wheat cultivars. Seed treatment by Raxil (0.1%) was found to be least effective in reducing the disease severity.
