BCR analysis for five selected fungicides and bioagent (Pseudomonas fluorescens) recorded highest in Propiconazole (1.72:1) followed by Propineb (1.47:1), bioagent (P. fluorescens) (1.46:1), Myclobutanil (1.45:1), Carbendazim (1.34:1), Thiopanate (1.33:1) and in Control (1.13:1). This inferred that in treatment Propiconazole investment of Re.1.00 will generate gross income of Rs.1.72 or net return (Re.0.72) and net return following other treatments i.e, Propineb (Re. 0.47), P. fluorescens (Re.0.46), Myclobutanil (Re.0.45), Carbendazim (Re.0.34), Thiophanate (Re.0.33) and in case of control (Re.0.13).
