The objective of present study was to assess the efficacy of individual and mixture of talc based bioformulations of Plant Growth Promoting Rhizobacteria and Trichoderma in the management of sugarbeet root rot caused by Sclerotium rolfsii. The result from field experiments revealed that next to the chemical treatment, significantly lower root rot incidence of (18.6%) was recorded in the combination of Pseudomonas fluorescens (Pf1)and Trichoderma asperellum (TTH1) followed by the combination of P. fluorescens (Pf1) and Bacillus subtilis (EPCO16) with 20.5% as against 28.5% in untreated control. However, the combination effect was not observed while combining TTH1 and EPCO16 as they are incompatible with each other. In the same way, increase in improvement of yield parameters was recorded in Pf1+TTH1 followed by Pf1+EPCO16 under field conditions. The results suggest that the approach of combined application of compatible biocontrol agents may provide improved biocontrol efficiency in controlling the crop diseases.
