Author(s): Muralidhar Mysore Kalpashree and Koteshwara Anandarao Raveesha
Abstract: Aqueous extracts of 25 plants selected from local flora were evaluated for antifungal potential against Alternaria solani by Poisoned Food Technique and Dry Mycelial weight method at five different concentrations viz.10%, 20%, 30%, 40% and 50%. Maximum Inhibition activity was observed in Poisoned Food Technique, Prosopis juliflora recorded 88.9% inhibition at 50% concentration followed by Carica papaya (77.84%), Ricinus communis (70.5%) and Polyalthia longifolia (63%). Dry Mycelial weight method revealed 90.7% inhibition by Prosopis juliflora, followed by Carica papaya (89.47%), Ricinus communis (86.1%) and Polyalthia longifolia (79.2%). Significant inhibitory activity was also observed in 10, 20, 30 and 40% concentration in both the methods. Among the 25 plants tested Prosopis juliflora, Carica papaya, Ricinus communis and Polyalthia longifolia plant extracts significantly reduced the mycelial growth of the pathogen in both the tests conducted.
