The anti-phytopathogenic activity of crude and methanol extract of leaves, Stem bark, seed and dry fruit of Terminalia thorelli was tested by disc diffusion method, against four phytopathogens. Crude aqueous extract of plant parts taken of 5 mg concentration showed zone of inhibition ranging from 11-22 mm. Xanthomonas axanopodis pv. malvacearum was found to be highly susceptible with highest zone of inhibition suggesting the strong inhibitory activity of these extracts towards the selected bacterial pathogens. These pathogens were more sensitive to the methanol extracts forming 13- 28 mm zone of inhibition suggesting that the methanol extract is little more effective than crude extract. These results indicate that these extracts can be exploited for the biocontrol of phytopathogens.
