El mango es susceptible a una enfermedad postcosecha denominada antracnosis, causada por el patógeno Colletotrichum sp. Los fungicidas han sido utilizados para controlar las enfermedades ocasionadas por hongos; sin embargo, ocasionan daño al medio ambiente. El quitosano posee propiedades antimicrobianas e induce resistencia en las plantas, en esta resaltan algunas enzimas,
como la peroxidasa (POD). El objetivo de esta investigación fue evaluar el efecto del quitosano en la inducción de resistencia contra Colletotrichum sp. en frutos de mango. A nivel in vitro el quitosano inhibió la germinación de esporas, la elongación del tubo germinativo y el crecimiento micelial de Colletotrichum sp. Para los tratamientos aplicados a los frutos en postcosecha, el quitosano a concentraciones de 1.0 y 1.5% inhibió por completo a Colletotrichum sp.
