dc.description.abstractBiological control is the reduction in the amount of inoculum or disease producing activity of a pathogen accomplished by or through one or more organisms other than man. Its usefulness is more prominent for soil borne disease management where management by other means are difficult. Trichoderma spp. have gained considerable success in this respect. In the in vitro studies, T. harzianum Rifai Anand isolate (ThA) could sporulate maximum in wheat bran-sawdusttap water carrier. Among various liquid media evaluated in the study, Brown's and Elliott's medium supported maximum fungal growth. A pH range of 4 - 6 was found most suitable for the growth of T. harzianum Anand isolate. The spores of T. harzianum Anand isolate could not germinate when exposed to 55 °C even for 5 minutes. In dual culture T. harzianum (Anand), T. harzianum (Junagadh), T. harzianum (Pantnagar) and T. koningli (Pantnagar) showed more or less antagonistic effect against Rhizoctonia bataticola (Taub.) but l . and Sclerotium rolfsii Sacc . but did not show antagonistic activity against Fusarium oxysporum f. sp. cumini Prasad and Patel . Hyphal interaction and production of non-volatile compound might be the main mechanism responsible for antagonism. In vivo studies T. harzianum Anand isolate alone could reduce the infection of R.bataticola and S. rolfsii at significant level but a combination of fungicides carbendazim and TMTD respectively with T. harzianum Anand isolate was nrast effective in suppression of both the pathogen.en_US
