In-vitro characterization of biocontrol potential of Trichoderma isolates

The variability in the biocontrol potential of Trichoderma spp. is a consequence of its colonization in different agroclimatic zones. Thus in this study was focused on isolation and screening out robust isolates of Trichoderma spp. from various district of Uttar Pradesh that could be useful in biological control of three prevalent sclerotia forming soilborne plant pathogens namely Rhizoctonia solani, Sclerotium rolfsii and Sclerotinia sclerotiorum. 80 isolates of Trichoderma spp. R. solani was maximally inhibited by Trichoderma isolates BHU-150, while S. rolfsii and S. sclerotiorum were largely by BHU-51 isolate.
