Abstract– Every year farmers face 10-40 percent grain yield loss on maize cultivation, Maize is one of the important crops that consume low water, highly nutritious, fast-producing crops. Blended leaf and Sheath blight is a serious disease caused by a soil-born fungus Rhizoctonia solani, multi nuclei septate hyphae, branched, white, and dark brown colonial fungus, affect leaves, stalk, and ears. Irregular water-soaked straw colour spot on leaf sheath and dark brown stalk. Artificially inoculated BLSB on Maize field at Dr. Shyama Prasad Mukherjee University’s campus area, Seeds were purchased from Birsa Agriculture University, Ranchi. Invasive plant leaves and green stem parts are boiled for six hours and collect their extracted solution. Total seven treatments were designed, four biopesticide treatment were provided individually (T1, T2, T3, T4) including a control – T7 and a chemical pesticide treatment -T5 and T6 only inoculated with infection. Spry thrice a week and compare their infection rate. T2 treatment shows the best result, T4 is better than T1, T3 and T5 shows more or less similar effects and T6 infected plot without treatment showing massive loss of productivity.
