Abstract
Among silkworm diseases, white muscardine is the most virulent and contagious disease
caused by the fungus, Beauveria bassiana. In the present study, 30 aqueous extracts of plant
products were tested in vitro against Beauveria bassiana. Of them, Garlic (Allium sativum)
bulb, Ginger (Zingiber officinale) rhizome, Turmeric (Curcuma longa) rhizome, Cardamom
(Elettaria cardamomum) seeds, Safed AK (Calotropis procera) leaves, Walnut (Juglans regia)
epicarp and Pumba chalan (Rheum australe) root were found effective in inhibiting the conidial
germination and vegetative mycelial growth of Beauveria bassiana at 1% concentration in 30
minutes duration. Safed Ak (Calotropis procera) and Walnut (Juglans regia) were found
effective at 0.5% - 1.0% in 30 minutes duration
Key words : Plant products, Beauveria bassiana, in vitro effects.
