Abstract:
In vitro compatibility of selected entomopathogenic fungi with botanicals and chemical insecticides at field recommended concentrations indoxacarb, Spinosad, Neem oil and NSKE were non-toxic to the test strains of B. bassiana (Bb-L-2) did not show significant reduction in radial growth. The insecticide Diclorovos (DDVP) recorded 100 per cent reduction in radial growth of test strains at field recommended concentration. The joint action of microbial agents (bacteria, viruses and fungi) revealed that the combination of pathogens did not prove superior to individual effect. All the combination of entomopathogenic fungi (B. bassiana (Bb-L-2) strain with microbial agents were within the critical limits of additive effect and combination with insecticides viz., Spinosad 45EC @0.009%, neem oil 5% and NSKE 5%, which produced the synergism reaction.
