Among the silkworm diseases, white muscardine caused by Beauveria bassiana is the most common disease. The seven different chemicals viz., BKC (90%), pine Oil (100%), bleach (12%), sodium chlorite (80%), bleaching powder (30%), sanitech (2000ppm) and hydrated lime (80%) were tested and screened against fungus (beauveria bassiana and bacteria (bacillus and staphyllococcus) based on poison food technique with different concentrations such as 0.05%, 0.5%, 1%, 2%, 2.5%, 3%, 5%and 10% with three replications for each chemical concentration along with control. Among all the chemical the BKC (90%) gave better result. all the six concentration viz., 0.5, 1.0, 1.5, 2.5, 5 and 10 were tested against fungus (beauveria bassiana) and bacteria ( bacillus and staphylococcus). The maximum inhibition was recordrd in 10 % concentration of BKC followed by 5% .The minimum inhibition of radial growth of fungus was recorded in Pine oil i.e. 5% concentration followed by 2.5% .In case of bacterial pathogen 5 and 10% concentration shows maximum inhibition and 2.5% concentration shows partial inhibition. In general, the inhibition of radial growth of fungus increased with increase in concentration of each chemical.
