Abstract

Compatibility of six strains of Beauveria bassiana with four commonly used insecticides, viz., imidacloprid, spinosad, indoxacarb and chlorpyriphos, was tested to identify and incorporate the compatible strain(s) in IPM against Spodoptera litura. All the strains were compatible with imidacloprid and spinosad. Indoxacarb showed no significant inhibition of radial growth of B. bassiana strains, but caused significant inhibition of sporulation and spore viability in some strains. Chlorpyriphos was found to be highly incompatible with all the strains and exhibited high inhibition of growth and complete inhibition of sporulation and spore viability.
