Incidencia del daño de la antracnosis (Colletotrichum gloeosporioides) en el cultivo de papaya (Carica papaya L.)

It is well known that anthracnose is the most important disease of the papaya crop(Carica papaya L.) in Ecuador and that its causal agent is the hogo(Colletotrichum gloeosporioides), so in this work the damage caused by characterizing the symptoms and damage is described by specifying the methods of disease control. Using the methodology of collecting information related to the topic from the internet and its variety of channels of access to reliable information source such as scientific articles, theses and others, where then the analysis and drafting of the idea of each of them was performed until the satisfactory compilation. The existence of 17 genera and 25 species of pathogens that affect the papaya crop was compiled, among them five of the Colletotrichum genus, registering two species in Ecuador, but C. gloesporioides and C. acutatum, but the first is the one with the highest incidence. Anthracnose presents symptoms at the beginning with gummy exudates, followed by small lesions that turn brown with yellow halo with a tendency to sink at the edges, which then merge covering a larger area of the fruit, with a central sink of gray to brown color with salmon to pink dots where the reproductive structures of the fungus are located. As the fruit ripens, the epidermis softens and larger lesions are established.
