Bioactivity of Ethanolic Extracts of Dipteryx punctata on Colletotrichum musae

Bioactivity with antifungal properties has already been reported for some species of the genus Dipteryx. However, little is known about Dipteryx punctata. We evaluated activity, in vitro and vivo, extracts leaves, branches fruits D. punctata on Colletotrichum musae, causal agent anthracnose bananas. The coumarin standard were tested vitro, at concentrations 10%, 20%, 30%, 40%, 50% (w/v), added potato-dextrose-agar (PDA) medium. experimental design was completely randomized, factorial design, four replications. average diameter fungal colonies daily eight days, end, percentage inhibition growth rates calculated. For vivo tests, products 40% 50%, preventive curative applications. In these three medium disks (5 mm) containing phytopathogen structures deposited opposite points fruits, remained a humid chamber 48 h. Anthracnose lesions measured an interval two up to days after fungus inoculation. essay, residues pattern caused biggest reductions phytopathogen. promising terms especially applications, being important source investigation formulation natural as sustainable phytosanitary measures.
