Tommy Atkins, irrigated by microsprinklers, in order to support epidemiological studies in Petrolina, Pernambuco State, Brazil. Mathematical models were obtained by relating microclimatic with macroclimatic conditions. Inside the orchard, comparing with data from automatic agrometeorological station near the experimental area, the air temperature showed values up to 0.5oC lower and 0.3oC higher at hotter and colder hours, respectively. The air relative humidity reached values 9% and 6% higher, respectively at hotter and colder hours. The thermal and umidity amplitudes inside the orchard were lower in relation to outside the orchard. Wind speed values inside the orchard were, on the average, up to 1.9m/sec lower. The values of leaf wetness duration show a good correlation with The air relative humidity/air temperature index. This last index seems to be a good indication for spore germination conditions.  aClima  aEsporo  aGerminação  aManga  aModelo Matemático  aUmidade Relativa  aAvaliação  aFolha de planta  aTemperatura do ar  aVelocidade do vento1 aREIS, V.
