Abstract: Exploring eco-friendly fungitoxicants is a current need in the context of hazardous effects of chemical fungicides. In the present work, inhibitory effect of two common spices viz. cinnamon and garlic was evaluated against Rhizoctonia bataticola, a common soil borne pathogen of green gram. The inhibition of R. bataticola growth with different concentrations of both these spices was in the range of 26.25% to 100% by poisoned food technique. The inhibitory effect of different concentrations of carbendazim and copper oxychloride was in the range of 43.75& to 100%. Autoclaving of the medium along with spices resulted in increase in growth inhibition of the pathogen as compared with the inhibition due to spices when added after autoclaving. Aqueous extracts prepared with boiling were more effective than the extracts prepared without boiling. Antagonistic potential of the spices was evaluated in terms of increase in seedling vigor index (SVI) of green gram seeds inoculated with R. bataticola by paper towel method. The increase in SVI was in the range of 25.85% to 45.03% with independent treatments of garlic and cinnamon to the pathogen inoculated seeds. SVI of the pathogen inoculated seeds increased by 30.43% with 1% carbendazim.
