Abstract

Different substrates viz. sorghum, maize, pearl millet, barnyard millet (Echinocloa frumentacae) and cow dung were evaluated for mass multiplication of Beauveria bassiana (Balsamo) Vuillemin. Sorghum grains were found to be best and exhibited maximum population (6.32 ×109 cfu) followed by maize (each grain broken into 8-10 pieces) with 5.77 ×109 cfu and barnyard millet (5.08 ×109 cfu), respectively. Addition of 1 per cent sucrose increased the growth and sporulation of B. bassiana in sorghum (6.65 ×109 cfu) and barnyard millet (6.24 ×109 cfu). However, population of B. bassiana was significantly reduced in sorghum and barnyard millet grains when amended with 2 per cent sucrose.
