Eight different organic substrates rice husk, wheat straw, wheat bran, cotton waste, maize stover, saw dust and sugarcane bagasse were screened for their effect on spore production and growth (cfu/gm) of three different species of Trichoderma i.e. T. harzianum, T. longibrachiatum and T. viride isolated from rhizosphere of Dalbergia sissoo. Wheat bran supported maximum growth (19.75) cfu/gm and conidial production (2.98) per gram of substrate for biocontrol agents. T. harzianum showed maximum population (16.57) cfu/gm and T. viride yielded maximum no of spores (2.77) per gram utilizing all the substrates. A temperature 25 degree C was observed best for their mass multiplication. Soil application of organic preparation of biocontrol agents was effective in managing seed borne pathogenic fungi F. oxysporum, F. moniliforme, F. solani, B. theobromae, A. alternata and R. solani and in seedling establishment of Dalbergia sissoo Roxb.
