Bio-agents including an unrecorded genera of yeast {Sporidiobolus pararoseus (KFY-1) (MTCC No. 8337)} were evaluated against Botryodiplodia theobromae for the efficacy to manage the stem end rot disease. Among the fungal bio-agents, Trichoderma viride-1 and T. hamatum (HP-20) proved to be most effective against B. theobromae, inhibiting the mycelial growth of 68.7 and 66.3%, respectively as compared to control. Pseudomonas fluorescens (Pf-1) was found most effective bacterial bio-agent which inhibited 84.8% growth of pathogen followed by Bacillus subtilis (64.0%) while, the both yeast bio-agents viz., Debaryomyces hansenii and S. pararoseus (KFY-1) potentially checked the growth to the tune of 83.1 and 80.9%, respectively. Minimum incidence (11.9%) of rot was recorded in the fruits, treated with P. fluorescens (Pf-1) as pre-inoculation treatment followed by D. hansenii (16.2%) and S. pararoseus (KFY-1) (20.0%). B. subtilis was found next in order of efficacy in reducing the incidence to 26.2% as compared to control (70.7%).
