Abstract:
Increase of environmental pollution due to use of pesticides is alarming. One of the alternatives is to reduce the pesticide use and use of botanicals as biocontrol agents. The present investigation was undertaken to test antifungal activity of four RET medicinal plants <em>viz., Oroxylum indicum</em>, <em>Embelia ribes, Celastrus paniculatus, and Saraca asoca </em>against four phytopathogens <em>viz., Sclerotium rolfsii</em>, <em>Fusarium oxysporum</em>, <em>Alternaria solani</em>, and <em>Phytophthora capsici</em> was screened <em>in-vitro</em>. Aqueous leaf extract of <em>E. ribes</em> and <em>O. indicum</em>at 15% concentration provided a significant inhibition of mycelial growth of fungi. <em>E. ribes</em> leaf extract inhibited the mycelial growth of <em>A. solani </em>and <em>F. oxysporum </em>upto 86.52% and 43.26% respectively, whereas leaf extract of <em>O. indicum</em> inhibited the fungal growth of <em>S. rolfsii</em> up to 80.39%. Thus the present study revealed that these two plant extracts have proved to be effective as bio control agents for suppressing the growth of phyto pathogens.
