In this study, the biocontrol abilities of water-soluble and volatile metabolites of the three different isolates of Trichoderma (T. asperellum, T. harzianum and Trichoderma spp.) against soil born plant pathogen Rhizoctonia solani was investigated in-vitro and in-vivo. The results showed, for the first time that Mycelial growth inhibition of the pathogen was 74.4-67.8% with water–soluble metabolites as compared to 15.3-10.6% with volatile metabolites in vitro. In-vivo antagonistic activity of Trichoderma isolates against R. solani was evaluated on bean plants under laboratory and greenhouse conditions. We observed that T. asperellum was more effective and consistent, lowering disease incidence up-to 19.3% in laboratory and 30.5% in green house conditions. These results showed that three isolates of Trichoderma could be used as an effective biocontrol agents against R. solani.
