The challenge
As coffee rust is a foliar disease, infections are diagnosed by premature leaf fall and orange irregular shaped spots on the upper leaves. At the bottom leaves orange powdery lesions can be observed, which contain the spores that will be transmitted to initiate a new infection cycle. If no preventive measures are taken, infected leaves will drop, which might result in tree death in severe occasions. Therefore, Huwa-San TR-50 was used as a biocide to prevent thriving of this fungus, and also to guarantee healthy trees and coffee beans.
