metadata.revistascielo.dc.description: The study aimed at studying leaf extracts and essential oils of Eremanthus erythropappus on spore germination of four rust species: Puccinia psidii, Hemileia vastatrix, Phakopsora pachyrhizi and Cerotelium fici, and on mycelial growth of Cilindrocladium scoparium. The fungitoxic effect of the extracts used led to absence of urediniospore germination in all rust etiologic agents tested. Mycelial growth inhibition of C. fici was higher with methanol extract (52%), subsequently reducting spore production. Treatments with tea at 10% and essential oil at 1% reduced mycelial growth (25% for both treatments) and spore production (28% and 34%, respectively). Therefore, Eremanthus erythropappus extracts shoud be studied for controlling rust and C. scoparium in eucalyptus.
