Abstract
Among the various biotic constraints, stripe rust is known to cause significant losses in grain yield and quality of wheat. In this study, out of 20 varieties evaluated, WH-1105, WH-1121, WH-1124, WH-1142, VL-804, VL-907, HS-240 were found to be resistant; RSP-561, Raj-3765, PBW-664, PBW-590 were moderately resistant; Raj-3077, PBW-373, PBW-175, PBW-527, PBW-621, HS-490 were moderately susceptible, and PBW-343, PBW-550,HD-2967 were susceptible. Rust progressive curve had the highest value of 2,377.42 during 2014/2015 due to conducive environmental conditions, while in 2015/2016, it was 2459.4.The disease severity ranged from 1.0 to 15.30% at 10thof February in 2014/2015, while this range in 2015/2016 was 1.0 to 13.39%. The highest yield (44.95 q ha-1) was found in the plot treated with two sprays of Tilt @ 0.1% followed by two sprays of Folicur (43.47 q ha-1) and Bayleton @0.01% (43.2 q ha-1), respectively. Two sprays of Tilt (0.01 %) at 15 days interval gave minimum disease severity i.e. 4.03% followed by Folicur (5.29%) and Bayleton @ 0.01% (8.90%). The yield increased up to 34.60% when treated with two sprays of Tilt (0.01%) at 15 days interval.
