Abstract: Maize is kharif season crop and member of grassy family Poaceae. Northern corn leaf blight caused by Exserohilum turcicum (Pass.) Leonard & Suggs having worldwide importance devastating disease causes severe losses in yield. In-vitro, the effectively colony growth of fungus E. turcicum was inhibited through different fungicide at different concentration and different bioagent. Among the fungicides tested were capable of inhibiting the growth of E. turcicum at various concentrations; the hexaconazole 5 SC was the most effective fungicide with 96.17 per cent mean mycelial growth inhibition and significantly superior over rest of the treatments, while fenamidon 10% + mancozeb 50% WG found second best fungicide. Azoxystrobin 23 SC was found least effective fungicide with mean mycelial growth inhibition of 18.15, 32.22 and 58.89% at all the tested concentrations. Among different Trichoderma spp. tested against E. turcicum, maximum inhibition was recorded in T. viride (NAU isolate) (70.74%) which was statistically at par with T. asperellum (AAU isolate) (70.63%) with fungal colony diameter of 26.33 mm and 26.43 mm of E. turcicum. While, least inhibition was recorded in T. harzianum (JAU isolate) (54.37%) with fungal colony diameter of 41.07 mm of E. turcicum as compared to the control.
