Se recolecto 20 hojas de cada una de las 17 especies, cuatro hojas eran dispuestas por caja gerbox, totalizando cinco repeticiones, mantenidas por 10 dias en condiciones de fotoperiodo de 12 horas de luz y temperatura de 24 + o- 1oC. Los hongos esporulados en las hojas fueron repicados para placas de Petri con medio BDA (patata- destroxa- agar). La intensidad de la enfermedad fue obtenida por la relacion matematica entre incidencia y severidad. Las pruebas estadisticas fueron realizadas con el software Assistat, se utilizo la prueba de medias de Duncan al 5% de probabilidad de error. Se verifico diferentes reacciones de severidad dependiendo del material del eucalipto utilizado.
