Spot blotch caused by Bipolaris sorokiniana (Sacc. in Sorok.) Shoem. is an important disease of Wheat and Barley. The biological control has been proved useful and economical in the control of spot blotch because of the harmful effect of fungicides to human and environment. The Trichoderma viride, Trichoderma harzianum and Trichoderma virens were used in dual culture method to see their effect on mycelial growth of Bipolaris sorokiniana. The inhibition varied among Trichoderma spp. was ranged from 60.76 to 73.07%. The bioagent Trichoderma viride exhibited maximum inhibition percentage (73.07%, 72.30%) on mycelial growth of Bipolaris sorokiniana. The seed and soil treatment with Trichoderma viride increased plant height, fresh and dry weight of shoot and root as compared to control. Soil treatment with Trichoderma viride (bio agent) was found best with minimum disease severity (21.51%) and minimum percent root infection (10.00%).
