Diseases that attack the root: Incidence of infection in root Severity of root infection 2. Diseases that attack the stem: Incidence of infection in stem Severity of infection in stem 3. Diseases present in leaves: Severity of infection leaves 4. Diseases that attack flowers: Incidence of infection in flores.- 5. Diseases that attack the fruit: Incidence of infection in the fruto.- The plant material used was the seeds of plants uvilla Seedbeds, transplant and low greenhouse inoculation were performed at a temperature of 21-32 ° C and a humidity of 90%. After analyzing the following results: The fungus Alternaria sp. Is present in the aerial part of the plants in both leaves and stems fungus rapidly invades tissues causing mild to severe damage defoliation of plants may occur when there is a strong attack has an incidence of 4 to 7% and severity in a 17 and 19% in both Yaruqui and Amaguaña.
