Maize(Zea mays L.) is the third important cereal crop in agriculture world. It serves as food for human and feed for live stock. Like any other crop,maize is also attacked by several diseases. One example of such a disease is Banded Leaf and Sheath Blight of maize caused by Rhizoctonia solani For the management of this disease,a field trial was conducted using cultural practices, bioagents and fungicides,during kharif 2008 and 2009 at Research Farm of HAREC, Dhaulakuan. Out of 11 treatments, minimum disease intensity(1.36 on 1–5 scale) and maximum yield(42.28 q/ha) was found in case of foliar spray of validamycin (0.25%) followed by Tilt (0.1%) and bavistin (0.1%). Foliar spray of Indofil M-45 (0.25%) was found to be least effective among all chemicals,but showed significantly lower disease severity and higher grain yield over check. Use of bioagents given as foliar spray showed more effective response against the disease when compared with seed treatment. Trichoderma viridae was found more effective than Pseudomonas florescence.In all the treatments,there were significant increase in yield over check.
