In Vitro antifungal potency of plant extracts against five phytopathogens

The antifungal activity of aqueous extract of Cannabis sativa, Parthenium hysterophorus, Urtica dioeca, Polystichum squarrosum and Adiantum venustum was investigated against Alternaria solani, Alternaria zinniae, Curvularia lunata, Rhizoctonia solani and Fusarium oxysporum at different concentrations (5, 10, 15 and 20 percent). At 20 percent, maximum antifungal potential was observed with the extracts of C. sativa, which recorded excellent inhibitory activity against C. lunata (100 percent), A. zinniae (59.68 percent), followed by leaf extract of P. hysterophorus (50 percent) against A. solani. The application of botanical extracts for disease management could be less expensive, easily available, non-polluting and eco-friendly.
