Conteúdo: | Abstract: Viticulture in Brazil has been growing in importance in recent years. Among fungal diseases, the phomopsis (Phomopsis viticola) is one of the main diseases affecting this crop in Brazil, with important damage effects on its production. The objective of this study was to predict the favorability of incidence of the phomopsis on grape under the climatic change conditions in Brazil, based on criterions of mathematical logic associating combinations of ranges of climate variables with classes of favorability and using Geographical Information System - GIS tools. The study considered the months throughout the year of periods of 1961-1990 and 2071-2100, scenario A2 of IPCC. Mean temperature and relative humidity were the basic weather data entered in the GIS database. Leaf wetness duration was estimated from relative humidity measurements. Climatic data entered in the GIS were used to calculate and produce maps depicting the favorability of incidence of the phomopsis, through the application of disease favorability criterions. Areas of classes of favorability were calculated considered the country and Northeast and South regions. There is a tendency in the future to increase the favorability of incidence of the phomopsis on grape considering Northeast and South regions. The adopted methodology permitted quantifying the area of favorability of the phomopsis on grape not only in spatial terms, identifying the variability among the different regions of the country, but also in temporal terms, along the months, making an adequate distinction of the studied regions.
