In vitro experiment was conducted at the PG Research Laboratory, Department of Plant Pathology, N. M. College of Agriculture, Navsari Agricultural University to find out the efficacy of medicinal plants extracts against A. solani causing tomato early blight. The extracts of garlic bulb produced significantly maximum growth inhibition (58.15 PGI) against A. solani. This was followed by extracts of datura leaves (52.63 PGI). Extracts of lantana and neem leaves, ginger rhizome, onion bulb, leaves of kadvimahendi, eucalyptus, holy basil, jetropha and periwinkle showed 49.47, 44.21, 43.15, 41.05, 38.94, 36.84, 36.84, 33.68 and 19.21 PGI, respectively.
