Aqueous extracts from plants commonly used in medicine, food, or that traditionally have been associated with some antifungal effect, were tested against Colletotrichum musae and Fusarium proliferatum, two of the main fungi causing banana crown rot (PCB). Extracts of Gliricidia sepium and Eucalyptus globulus were the most effective to reduce colony growth and lesion depth in banana fingers inoculated with C. musae. Extracts of Thymus vulgaris and Allium sativum reduced colony growth of F. proliferatum. The most effective extracts for reducing lesion development were E. globulus, Neurolaena lobata and T. vulgaris. E. globulus was active in vivo for both C. musae and F. proliferatum. There were less extracts with inhibitory activity in vitro for F. proliferatum and the results obtained in vitro and in vivo differed. For C. musae the results obtained in vitro and in vivo were similar.
