Abstract: In order to study the antifungal activities of Pueraria peduncularis extracts, so as to lay the base for the development of effective, safety, and environment- friendly biopesticides and for the comprehensive development and utilization of Pueraria peduncularis. The antifungal activities of Pueraria peduncularis extracts against Rhizoctonnia solani, Venturia pirina, Fusarium avenaceum, Alternaria solani and Alternaria alternate were tested by means of mycelium growth rate method. The extracts of Pueraria peduncularis showed strong antifungal activities against Rhizoctonnia solani, and the equation of toxicity regression was y=1.5599x+ 1.2562, and R=0.9640, EC50=0.2525 mg/mL. Strong antifungal activities were also showed against the other four fungi with the inhibiton rate over 80% at the concentration of 10 mg/mL. The extracts of Pueraria peduncularis showed strong antifungal activities with broad control spectrum, and it was worth of further research and development of new biopesticides and comprehensive utilization. Key words: Pueraria peduncularis; plant extracts; antifungal activity
