Relación entre la incidencia y la severidad de la roya del café (Hemileia vastatrix) en San Ramón, Chanchamayo, Perú

Abstract

This work was carried out with the objective of determining the relationship between the incidence and severity of coffee rust (Hemileia vastatrix) in central jungle of Peru. The study was carried out at the Fundo “La Genova” of the Regional Institute of Jungle Development in San Ramón (Chanchamayo), Junín Region, central jungle of Peru. For this, in an experimental coffee field of approximately one hectare, 184 random plants were taken in which both the incidence and severity of the disease were measured. A direct relationship was found between the incidence and severity of “coffee rust” in Peru, confirming the advisability of evaluating only the incidence, as it is a practical, cheap, simple and easy-to-learn method for technicians and farmers.
