Abstract: The antagonistic potentialities of six species of native Trichoderma viz., T. asperellum (KU933475), T. koningiopsis (KU904460), Hypocrea lixii (KX0113223), T. harzianum (KU904458), T. ovalisporum (KU904456) and T. atroviradae (KU933472) were evaluated in vitro against Rhizoctonia solani causing sheath blight of rice. The current study of dual culture assay, revealed the percentages of mycelial growth inhibition of R. solani by T. asperellum (KU933475), T. koningiopsis (KU904460), Hypocrea lixii (KX0113223), T. harzianum (KU904458), T. ovalisporum (KU904456) and T. atroviradae (KU933472) were 56.44%, 68.44%, 75.5%, 66.6%, 63.1%, and 54.2% respectively. All the species considerably inhibited the growth of Rhizoctonia solani pathogen. The outcomes direct that the extent of inhibition by all the six species of Trichoderma provides use of excellent potential antagonists capable of reducing the growth of R. solani on sheath blight of rice.
