Abstract: The six different bio-agents viz., Trichoderma viride, T. harzianum, Trichoderma longibrachiatum, Pseudomonas fluorescens I, Pseudomonas fluorescens II and Bacillus subtilis were evaluated against Rhizoctonia solani through dual culture technique. Among six different bio-agents Trichoderma viride showed maximum (74.44 %) growth inhibition of the pathogen and appeared to be the most superior in its efficacy over all the antagonists tested. This was followed in sequence by T. harzianum (68.14 %), T. longibrachiatum (67.41 %), Pseudomonas fluorescens I (56.66 %), Pseudomonas fluorscens II (55.74 %) and Bacillus subtilis (47.77 %) were in decreasing order for per cent growth inhibition of Rhizoctonia solani.
