Abstract:

Aqueous extract of leaves of ten medicinal plants viz. Calotropis gigantia, Adhatoda vasica, Achyranthus aspera, Daucuscarota, Calendula officinalis, Aloe vera, Momordica monadelpha, Moringa pterygosperma, Eclipta alba and Ricinus communis was tested in-vitro at 0.20% and 0.50% concentration using poisoned food technique for antimicrobial activity against mycelial growth of Pyricularia oryzae (Syn. Magnaporthe oryzae) causing leaf blast and Helminthosporium oryzae (syn. Bipolaris oryzae) causing brown spot diseases in rice. The leaf extracts of all the ten medicinal plants were found significantly effective in reducing mycelial growth of the pathogens. The result reveals that the aqueous leaf extract of all the medicinal plants at the concentration of 0.50% was found most effective in minimizing the mycelial growth of both the pathogens.
