In order to determine the duration of the incubation periods (IP) and latency (PL) of the pathogen Hemileia vastatrix, its behavior over the years of studies and their relationship with climatic factors, a study was carried out from January 2017 to December 2019, in three locations in the coffee zone in the municipality of Third Front. In the laboratory, coffee plants of the variety Caturra of 6 months of age inoculated with the pathogen and transferred to the zones of studies. After 15 days of inoculation, it was evaluated daily: time of appearance of the first visible symptoms of the disease, number of plants with symptoms, time and number of leaves with lesions number of lesions per leaf, number of leaves with sporulated lesions and maximum and minimum temperatures. The Temperatures during the study ranged between 19 and 34 ºC. It was determined that the period of latency and incubation for the study areas La Mandarina is 33 and 19 days, Caimitón 32 and 21 days, Monjará 34.4 and 22 days, respectively.
