Studies on native isolates of fungal and bacterial bio-agents against collar rot of Chickpea

Sclerotium rolfsii Sacc, [teleomorph: Athelia rolfsii (Curzi)] causing collar rot of chickpea, is a devastating soil-borne fungus. It is reported almost all over the world with 10 to 30% yield loss is recorded annually according to severity of the disease. It is more serious at seedling stage causing plant mortality ranged from 54.7 to 95%. The present investigation was undertaken to find out bio-efficacy of twenty native isolates of Trichoderma spp. isolated from rhizospheric zone of eight different crops from different locations of Jabalpur by using serial dilution method against Sclerotium rolfsii and their effects on growth parameters of chickpea plant.
