The present investigation was undertaken to asses combined application of fungal and bacterial antagonists (Trichoderma harzianum & Pseudomonas fluorescens-27) applied as seedling root dip and foliar spray against the sheath blight of rice caused by Rhizoctonia solani under glass house conditions. Seedling root dip with T. harzianum + P. fluorescens-27 and foliar spray with T. harzianitm was the most effective in reducing the disease severity (45.8–48.0%) and disease incidence (60.1–61.5%) followed by seedling root dip with T. harzianum + P. fluorescens-27 and foliar spray with P. fluorescens-27 which resulted in the reduction of disease severity (43.0–43.4%) and disease incidence (56.7–56.9%), respectively. Among all the integrated treatments, reduction of sheath blight was lowest In combination of seedling root dip with T. harzianum +P. fluorescens-27 with disease severity of (26.9–28.3%) and disease incidence of (31.5–34.7%).
