Abstract
La madera del cedro (Cedrela odorata) es considerada una de las más valiosas de América tropical. En el presente trabajo se informaron afectaciones fitopatológicas a la madera de árboles adultos de esta especie, que desde 1974 se registran en la región oriental de Cuba. Una muerte progresiva, con afectaciones al fuste, corteza y abundante exudación de goma, son los síntomas más comunes entre los observados. Esta enfermedad se considera la más importante de el momento, aunque se informaron otras enfermedades de menor daño y extensión. Se determinó el índice de infección en diferentes localidades de la provincia de Guantánamo, y se registró hasta un 44,32% en la zona de San Luís, Baracoa. Se hicieron aislamientos e inoculaciones de algunos patógenos fungosos, se analizaron muestras de suelo de las zonas afectadas y se realizaron cortes histológicos en madera, que establecen en detalles, el deterioro de la misma, tanto en el tronco como en las ramas.
