| Abstract: | Essential oils of Erigeron canadensis L. and Myrtus communis L. were tested in vitro as growth inhibitors against phytopathogenic fungi Rhizoctonia solani Kuhn, Fusarium solani (Mart.) Sacc. and Colletotrichum lindemuthianum (Sacc. & Magn.) Briosi & Cav. Both showed weak fungicidal acitivity, except the essential oil of M. communis that exerted a 60% growth inhibition against R. Solani at a dose of 1600 ppm. Microscopic observation revealed that the essential oil of M. Communis caused morphological alterations of hyphae of all fungi at 1600 ppm, while, at the same dose, only the hyphal morphology of C. Lindemuthianum was affected by the essential oil of Er. Canadensis. |
