The objective of this study was to evaluate the fungicidal effect of Moringa on anthracnose in mango (Mangifera indica L). Anthracnose is commonly treated by spraying with fungicidal chemicals; continuous use affects the ecosystem due to the residues generated, thus harming the quality of the fruit, its innocuity and the health of humans. This research tried out a process to achieve an extension of the shelf life of mangos by using Moringa oleifera Lam. Aqueous Extracts (EA) were obtained by infusion and Ethanol Extracts (EE) by simple maceration of the Moringa leaf (Moringa oleifera Lam). For the evaluation of the results, chromatic techniques were used through the Image J software. Quantitative data were obtained on the appearance of spots and their radial growth. Each of the extracts obtained was applied to the samples by means of two treatments, immersion and sprinkling, with varying concentrations: 10.0, 15.0 and 25.0%, respectively. It could be observed that the most effective treatment and concentration in the control of the propagation of the spots and the radial growth was EA_2 (Aqueous extract by immersion) at 15.0%. With the use of Moringa extracts, a soil propagation percentage of less than 20% was obtained with respect to that of the controlled samples with a propagation percentage above 80%. In addition, a radial growth three times less than that of the control sample was obtained over the same study timeframe.
