Incidencia de las principales enfermedades que se presentan en el cultivo de papaya (Carica papaya), en el Ecuador

Papaya cultivation within the production process is susceptible to destructive pests and diseases. The problems start from the nursery, continue in the field and even in storage from harvest and packing. From the phytosanitary point of view, one of the greatest limitations detected for papaya crop production is the presence of the ringspot virus (PRV-p). This disease is distributed in all the papaya-producing areas of Ecuador, presenting an incidence close to 100% and causing economic losses to the producer of more than 80%. Root and fruit rot caused by the fungus Phytophthora sp can be classified as another limiting disease for papaya cultivation, due to the high susceptibility of the varieties and to the soil moisture conditions that prevail in the areas of production during the winter season due to high rainfall. The information obtained was carried out through the technique of analysis, synthesis and summary, in order for the reader to know about the main diseases that occur in the cultivation of papaya (Carica papaya) in Ecuador. Due to the above, it was determined that the most important diseases in papaya cultivation are: ringspot (PRV-p), anthracnose (Colletotrichum gloeosporiodes) and root rot (Phytophthora sp). Continuous monitoring within the papaya crop allows verifying if there is any phytosanitary problem. Fungicide application systems allow control of papaya crop diseases. Proper agronomic management of the crop is important to avoid the presence of endemic diseases.
