Abstract
The antagonistic potential of seven species of native Trichoderma against Rhizoctonia solani f.sp. sasakii were evaluated in dual culture method which includes T. asperellum (KU933476), T. koningiopsis (KU904460), Hypocrea lixii (KX0113223), T. harzianum (KU933471), T. ovalisporum (KU904456), T. harzianum (KU904458), T. atroviridae (KU933472). Among them T. asperellum showed highest inhibition percentage (78.09%), followed by Hypocrea lixii by (70.95%), T. ovalisporum by (68.76%), T. atroviride by (54.22%), T. harzianum by (64.76%), T. koningiopsis by (64.76%) and T. harzianum by (62.38%) respectively. However, all the species considerably inhibited the growth of R. solani.
