Isolation, Evaluation and Characterization of Indigenous Trichoderma spp. for the Management of Wilt of Chickpea Caused by Fusarium oxysporum f. sp. ciceris

Background: Fusarium oxysporum f. sp. ciceris causing chickpea wilt, a significant soil-borne disease that causes severe crop losses. Trichoderma spp. is diverse fungal bio-control agent with the ability to limit plant growth through variety of ways. The goal this work assess efficiency indigenous isolated from rhizosphere different North Eastern districts Karnataka against wilt pathogen in vitro, as well investigate cultural and morphological aspects isolates. Methods: Dual culture approach was used antagonistic potential isolates inverted plate technique examine synthesis volatile compounds were cultured on potato dextrose agar medium for characterization. Under microscope, characters observed. Result: Twenty reported be effective F. ciceris, preventing mycelial by 48.52 91.85%. All produced amount inhibited 2.59 72.22%. At 72 hours after incubation, had radial mycelium formed fluffy elevated colony growth, margins ranging smooth wavy.
