dc.description.abstractTo ascertain the status of foliar blight disease, extensive survey was conducted in major wheat growing areas of Jammu division, viz., Jammu, Samba and Kathua in Rabi, 2022-23. Average infection index (AIDX) was recorded in village Jangichak (50.65%) of Kathua district and minimum in village Birpur (23.87%) of Samba district. Seven fungi viz., Bipolaris sorokiniana, Alternaria alternata, Alternaria triticina, Fusarium moniliforme, Curvularia lunata, Penicillium spp., Aspergilus spp. were isolated from the blighted wheat leaf samples. Ten wheat cultivars were sown under protected and unprotected conditions to estimate the yield loss. Among ten cultivars Agra local showed the maximum reduction in grain yield (36.08%) and test weight (20.22%), however minimum reduction in grain yield (11.05%) and test weight (8.88 %) was recorded in the cultivar RSP-561. Out of fifty two wheat genotypes screened for disease resistance under artificially epiphytotic conditions. Nine genotypes viz., DBW- 222, HD-3418, HD-3440, RSP-303, WH-1080, HD-3171, DBW-327, VL-2043, DBW-90 were found resistant with the AUDPC value in the range of 242.85-396.55. Among seven fungicides tested, tebuconazole+trifloxystrobin and azoxystrobin + difenoconazole were found highly effective and inhibited (100%) radial growth of test fungi viz., B. sorokiniana and A. triticina under In vitro conditions. Moreover, the bio control agent Trichoderma harzianum was found most effective against foliar blight pathogens with 79.00 per cent mycelial inhibition. Under field conditions, maximum per cent disease control (64.76%) and maximum yield (39.08q/ha) were recorded in trifloxystrobin + tebuconazole followed by azoxystrobin + difenoconazole (57.36 %) and (38.52 q/ha).
