stripe rust disease management of winter wheat through host resistance and fungicides under rainfed conditions in jammu, india

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 10^th of 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.
