Identification of Trichoderma species based on morphological characters and bio-efficacy against Fusarium oxysporum, Rhizoctonia solani and Sclerotium sclerotianum

In vitro study was carried during 2017–18 to evaluate the efficacy of Trichoderma isolates against important soil borne fungal pathogens. Under in vitro condition, the results revealed that Trichoderma sp. (isolate 5) effectively inhibited the radial mycelial growth of the pathogens viz., Fusarium oxysporum (83.0%), Sclerotium sclerotianum (68.0%) and Rhizoctonia solani. Trichoderma asperellum (isolate 6) effectively inhibited growth of R. solani (88.6%).
