Abstract

The present work aimed to evaluate the fungitoxicity of ginger (Zingiber officinalis) and eucalypt’s (Corymbia citriodora) aqueous crude extracts (ACE) concerning the Helminthosporium sp fungus. This pathogen was identified in the fibers of banana pseudostem, used in local handicraft production. The fungus mycelial growth and sporulation were evaluated in vitro, as well as the growth of fungus colony on banana fibers treated with these plant extracts. The fibers received the following treatments: preventative, curative and T0 (the inoculation process and the treatments with the ACEs were used at the same time). The in vitro results showed that the eucalypt crude extract was the most efficient in mycelial growth and in reduction of spores production. As for the in vivo treatment, it was observed that fibers, preventatively treated with eucalypt ACE, were not affected by Helminthosporium sp.
