Resumo:  The aim of this work was to determine the in vitro antifungal activity of ten essential oils on Alternaria solani SORAUER. The effect by direct contact and exposure to vapors was evaluated. The bioassays were performed using a completely randomized design and the method of paper discs inoculated with the oils facing phytopathogen discs; the fungal radial growth was evaluated. All the oils, except those from Citrus sinensis (L.) Osbeck (sweet orange), inhibited the mycelial growth until the seventh day. At day 14, a total inhibition was observed in the treatments with the oils from Pimpinella anisum L. (anise), Ocimum basilicum L. (white basil), Ocinum basilicum L. var. genovese (Genovese basil), and Piper auritum Kunth (anise caisimon). No fungicidal effect was shown by the volatile metabolites of the oils; however, the inhibition of A. solani mycelial growth was observed in the treatments with the extracts of Ruta chalepensis L. (ruda) and P. auritum. These results open new perspectives for the control of this pathogen.
