Abstract: Tomato (Lycopersicon esculentum Mill.) is one of the major vegetable fruit crop in the state of Maharashtra and widely grown in Marathwada region throughout year. It is known to be affected by several fungal diseases. Based on symptomatology rotten with typical soft and watery tomato fruit wth coarse grey colour growth yielded the growth of Rhizopus stolonifer on artificial media and proved pathogenic in causing fruit rot of tomato in artificial inoculation. Culture was purified and maintained for further studies. In in vitro study, all tested botanicals/plant extracts were found effective in inhibition of mycelial growth of R. stolonifer. least mycelial growth was recorded with maximum inhibition of 88.15% with treatment of Nilgiri oil which was at par with treatment of Garlic clove extract (84.07%) followed by Turmeric rhizome extract (81.11%). While least mycelial inhibition was recorded with Onion bulb extract (66.30%) and Tulsi leaf extract (64.07%), Neem leaf extract (54.07%) and Ginger rhizome extract (52.96%). All the tested chemicals were found fungistatic against R. stolonifer. Calcium chloride and Boric acid at both concentration 1 & 2% were found most effective in inhibiting the mycelial growth of Rhizopus stolonifer, while least inhibition of these fungi was observed with Potassium chloride and Sodium bicarbonate.
