The Costa Rica Coffee Institute (Icafe) issued a warning that variations in atmospheric conditions favor a high threat of coffee rust in a large part of the national coffee park, mainly in the Central Valley, Coto Brus, Turrialba and the North Zone regions, according to the Icafe.
A report by the Research Unit of the Technical Management of the Coffee Institute of Costa Rica, ICAFE indicates that in July there is usually a decrease in rainfall and the emergence of new lesions is less.
With an increase of warmer temperatures and weaker and less frequent rains, there is a greater presence of spores in the lesions. This promotes a great increase in disease when the return of heavy rains return in August. Due the this, the need to protect coffee trees at the end of the period of heat is crucial.
