La enfermedad de las cerezas del café (CBD): ocasionada por el hongo Colletotrichum kahawae por Cárdenas López, Jaime, Gómez Quiroga, Ramiro, Gil Vallejo, Luis Fernando

“…La enfermedad de las cerezas del café (CI3D), ocasionada por el hongo Collectotrichum kahawae, se detectó en 1922, al oeste de Kenia, en áreas con altitudes superiores a 1700 msnn. A finales de los años 60, la enfermedad se había diseminado a todas las áreas cafeteras de ese país, incluidas zonas con altitudes inferiores a las mencionadas, y en la actualidad se encuentra en toda la zona cafetera del continente africano (5,7,10,14.1 5.27). …”
