Isolates of Phakopsora euvitis, causal agent of grapevine rust, will be collected in three regions of São Paulo State for determining in vitro its sensitivity to strobilurin fungicide. Relationships between environmental variables (temperature, leaf wetness duration, relative humidity, rainfall volume, rainfall intensity) and the progress of grapevine rust (evaluations of disease incidence and severity) will be examined in areas where the damage caused by the disease will be evaluated.
