The growth parameters and infectivity of an entornogenous fungus, Zoophthora radicans (Brefeld) Batko were promoted significantly when cultured on Sabouraud Maltose Agar+50 per cent prawn exoskeleton (biomass 725 mg;radial growth: 84.75 mm;sporulation 90.71 %;infectivity:71.90%) followed by 75 and 25 per cent dosages, thus revealing it to be a suitable ingredient in the synthetic media.
