Antifungal activity of Acacia farnesiana extracts on the in vitro growth of Fusarium oxysporum f. sp. lycopersici

Plants produce compounds with antimicrobial properties that can be used for diseases control that affect cultivars of economic interest. The obtention of the vegetal extracts and identification of their active compounds will allow their application against different fungi. In this work we received two vegetal extracts: one aqueous-alcoholic and other plant species Acacia farnesiana. The antifungal activities were evaluated of the two extracts on the fungus Fusarium oxysporum f. sp. lycopersici by the percentage of inhibition of mycelial growth in time and were performed for phytochemical analysis. Both extracts showed more 90% of inhibition micelial growth in the first evaluation (72 hours) after of the inoculation. So, the vegetal extracts showed fungicide effect on the fungus. Besides, two vegetal extracts showed the presence of metabolites to microbial activity known as flavonoids, tannins, phenols, alkaloids and saponins.
