Abstract
Trichoderma spp. were known to have antagonistic activity against against many soil borne diseases. In this experiment we have prepared five different formulations of Trichoderma asperellum and stored them in normal temperature. Later the efficacy of all the formulations were checked against sheath blight disease of rice both in-vitro and in-vivo. Among formulations the F5 [Trichoderma grown in potato dextrose broth (500ml) + Talc(500g)] treated plants showed very good result in managing sheath blight of rice by enhancing the plant height, total number of filled grains and root length. All the formulations performed significantly better than untreated control plants. The F5 treated plants were also recorded to have less disease incidence with increased yield as compared to other formulations.
