The antifungal activities of aqueous (infusion and decoction) and ethanolic (tincture) extracts from a medicinal plant, Z. punctata, were evaluated on important fungal pathogens isolated from major crops of Argentina. Fungal species were Fusarium oxysporum, F. thapsinum, F. verticillioides, Macrophomina phaseolina and Rhizoctonia solani. Percentage of hyphal growth inhibition was evaluated by agar dilution method. Tincture was the most fungitoxic extractive form assayed. Inhibition of mycelial growth increases with concentration. Our results suggest that Z. punctata has a broader fungicidal activity than that previously showed and most fungicidal principles were in the tincture. Further research is needed to identify and characterize these bioactive compounds.
