ABSTRACT: In January and February 2013 occurred a South American leaf blight epidemic in regions considered as escape zones, causing concern to rubber tree growers and throughout the rubber industry. A possible adaptation of the fungus to escape zones was raised and the consistency of disease control by the use of the binomial: plants with uniform renewal of leaves + dry season, typical of the escape zones, was questioned. The aim of this work was to bring relevant information to the rubber growers about the interaction climate-pathogen-host and to compare normal climate (historical average) and climatic data of the occurrence period of epidemic (January and February 2013). We conclude that was not the pathogen that has adapted to rubber tree in drier conditions, typical in escape regions, but a more humid climate occurred in these drier regions during this period.
