Abstract
Influence of formulations, doses and time of application of Trichoderma harzianum and T. virens was evaluated to manage rice sheath blight, under field conditions. Talc+ CMC based formulation of T. harzianum was found best in reducing sheath blight (45.1%) and increasing grain yield (24.0%). Higher rate (8g/l) of the bio-agent(s) was found superior in reducing sheath blight as compared to lower doses. Fungal bio-agent(s) applied 7 days before inoculation of Rhizoctonia solani resulted 67.0% reduction of the disease as compared to simultaneous application.
