Abstract

Trichoderma isolates (SSBGT07, SSBGT08, SSBGT09, SSBGT10) were isolated from the soil samples of the South-Siberian Botanical Garden and identified using morphological observation and ITS region analysis as Trichoderma harzianum, T. asperellum, T. ghanense, and T. longibranchiatum. Antagonistic activity against Cladosporium sp. and Botrytis sp. was evaluated in vitro. All isolates showed antagonistic effect by competition against Cladosporium sp. T. asperellum and T. longibranchiatum showed antagonism against Botrytis sp. All isolates showed hyper sporulation on the sclerotia of Botrytis sp. (except the T. ghanense) and colonies of the Cladosporium sp. Our study provides new isolates that affect the Cladosporium sp. and Botrytis sp.
