Keywords: Seed borne pathogens | Antimicrobial activity | Solanum torvum | Paddy

Aqueous and Solvent extracts of leaves of S. torvum viz., Petroleum ether, Benzene, Chloroform, Methanol and Ethanol were tested in vitro for antimicrobial activity following the procedures of poisoned food technique and cup diffusion method against some important seed borne pathogens of paddy viz, Pyricularia oryzae, Alternaria alternata, Bipolaris oryzae, Tricoconis padwickii, Dreschlera tetramera, D. halodes, Curvularia lunata, F. oxysporum, F. moniliformae, F. solani and Xanthomonas oryzae. Aqueous extracts of leaves (at 25% concentration) showed 100, 47.44, 60.47, 71.50, 56.11, 63.33, 78.62, 66.66, 47.44 and 46.27% inhibition of the test pathogens respectively. Highly significant antifungal activity was observed in Methanolic and ethanolic extract. The percentage inhibition of the test pathogenic fungi in Methanolic extract was 100% (P.oryzae), 74.42 (A. alternata), 65.68 (B oryzae), 87.62 (C .lunata), 100% (T. padwickii), 63.33 (D.halodes), 60.31 D. (tetramera), 76.01 (F.moniliformae), 59.21 (F. oxysporum), 43.91% (F.solani) and zone of inhibition of Xanthomonas campestris pv oryzae was 18 and 30mm in Methanol and ethanol extract.
