Abstract : Using plant extracts (EV) to control plant diseases has increased in the last few years and its application is an important alternative in fresh fruits consumption. The objective of this research was to determine the effect of applicating EV of 'nim' (Azadirachta indica), 'flor escondida' (Phyllanthus niruri), 'algodón de seda' (Calotropis procera), 'orégano silvestre' (Lippia origanoides), 'mata ratón' (Gliricidia sepium) and 'rabo de alacrán' (Heliotropium indicum) on mango (Mangifera indica) fruit quality at postharvest. Physiologically mature fruits were inoculated with C. gloeosporioides and placed in a completely random design with four replicates and 13 treatments of the different EV; water was used as a control treatment. Results showed that physic variables: polar and equatorial diameter, fresh matter loss as well as the chemical variables were not significantly affected by the presence of the fungus neither the EV application; although fresh matter tended to diminish in time. As maturity process progressed, total soluble solids (SST) and SST/Acidity relation increased, while acidity values diminished. Appearance of EV treated fruits was less affected by the presence of C. gloeosporioides, compared to the control. In conclusion, mango fruits quality seems no to be affected by using plant extracts to control anthracnose.
