The study carried out at Mycology and Plant Pathology laboratory, University of Lucknow during 2015–16 revealed that the growth media impregnated with recommended concentration of imidacloprid, allowing the highest radical growth (70.2 mm) and maximum spore count per ml of spore suspension (297.2) of B. bassiana, next only to the untreated control at 76.0 and 332.2, respectively after 30 days of inoculation, proved comparatively most compatible. Tobacco extract with 50.0 mm radical growth and 295.2 ml-1 spore appeared next best in the compatability test with B. bassiana.
