Abstract:

The aim of the present experiment was to observe the effect of extracellular metabolites of the biocontrol agent Trichoderma pseudokoningii on the radial growth of four selected pathogens viz. Fusarium oxysporum, Colletotrichum capsici, Rhizoctonia solani and Sclerotinia sclerotiorum in in vitro conditions. The cell free culture filtrate of the bioagent was added @ 0, 5, 10, 15 and 20% (v/v) concentrations against the pathogens. Maximum inhibition in the radial growth of the pathogens was found when they were applied @ 20% concentrations of the culture filtrates. The treatments tested were not so much significantly different as compared to control where the difference was markedly visible as well as at highest concentration applied. Among the pathogens tested, highest control in the radial growth was found against C. capsici i.e. 65.01% (mean of three replications) followed by S. sclerotiorum (62.82%), R. solani (50.22%) and F. oxysporum (34.53%) proving that the extracellular metabolites released by the biocontrol agent have an effect on the growth of the pathogens.
