Zusammenfassung:Objective this study aimed to determine the thermal favorability for the oidium (Oidium caricae) and early blight (Asperisporium caricae) in areas of edaphoclimatic aptitude for the papaya (Carica papaya) in the Espírito Santo state, Brazil. The edaphoclimatic zoning was based on the overlapping of maps that characterize the average annual air temperature obtained by multiple linear regression, annual water deficiency calculated by the Thornthwaite and Matter method (1955) and favorable soil classes to the development of papaya. The results indicated that as regards the edaphoclimatic zoning for the papaya crop it was observed that 71.70% of the area is classified as apt for its development. In relation to agrometeorological favorability for the occurrence of fungal diseases, there was a favorability of 7.64% for the development without restrictions of the oidium and a predominance of 64,56% of favorability with thermal restriction. For the early blight fungus, it was observed that the zones of favorability without restriction correspond to 11.66% of the area apt for the papaya cultivation and that 55.13% of the area has favorability with restriction of humidity. The edaphoclimatic zoning for the papaya crop showed compatibility with the most productive areas of this crop in the state of Espírito Santo. The zoning of thermal favorability for the occurrence of papaya fungal diseases proved to be a valuable tool for studies of plant diseases, allowing the establishment of plans for the allocation of resistant varieties, in order to minimize the risks of loss of crop productivity due to the disease. This methodology presents potential to be used in other areas, cultures and phytopathological diseases.
