The expert stated that, at this stage, the coffee plantations have largely affected the leaves, situation manifested by spots or blotches that appear on the leaves.
The point of maximum infection occurs in the months of January and February. After this step, the rest of the dry season the phase of decent, where the leaves of the coffee plantations and the end of fall is not visible rust occurs. However, the attacks come back in the rainy season due to spores that survive in necrotic leaves are in coffee plantations, which give rise to new infections.
According Adán Hernández, producers must do the pruning of coffee trees during the drought to help in the elimination of residual rust.
