| Abstract:
The frequency of organisms associated with crown rot of banana (PCB) in Costa Rica was compared in two banana production systems. The organisms isolated were similar to those previously described by other authors and were common to the two systems (integrated and organic), but the frequency of recovery, overall, was higher in the integrated system. Organisms more frequently found in the integrated production system were Erwinia spp., Pseudomonas fluorescens, Fusarium proliferatum, F. semitectum, F. graminearum, other species of Fusarium, Lasiodiplodia theobromae, F. verticillioides, F. sacchari, yeasts and fungi that did not sporulate. In organic farming the highest percentage of fungi isolated were F. subglutinans, Acremonium sp. and Colletotrichum musae. F. verticillioides was only recovered in the integrated system. La frecuencia de organismos asociados a la pudrición de la corona del banano (PCB) se comparó entre dos sistemas de producción de banano en Costa Rica. Los organismos encontrados en ambos sistemas (integrado y orgánico) fueron similares entre sistemas y coincidieron con lo informado por otros autores. En general, la frecuencia de recuperación de organismos fue mayor en el sistema integrado. Los organismos más frecuentes asociados a PCB en el sistema de producción integrada fueron Erwinia spp., Pseudomonas fluorescens, Fusarium proliferatum, F. semitectum, F. graminearum, otras especies de Fusarium, Lasiodiplodia theobromae, F. verticillioides, F. sacchari, levaduras y hongos que no esporularon. En el sistema orgánico los organismos más frecuentes fueron F. subglutinans, Acremonium sp. y Colletotrichum musae. F. verticillioides fue recuperado solo en el sistema de producción integrada. | |
