Studies on the relative efficacy of biocontrol agents under in vitro and in vivo conditions showed that combined treatment of Trichoderma harzianum + Pseudomonas fluorescens was most effective followed by T. viride + P. fluorescens in management of Alternaria blight of cumin. Pseudomonas fluorescens when treated alone was least effective. Trichoderma harzianum + P. fluorescens recorded 40.86 per cent disease intensity with 35.95 per cent disease control and realization of seed yield of 3.63 q/ha which was 100.55 per cent more than that obtained in control.
