DUARTE, Yanisia; PINO, Oriela  y  MARTINEZ, Benedicto. Effect of four essential oils on Fusarium sp.. Rev. Protección Veg. [online]. 2013, vol.28, n.3, pp. 232-235. ISSN 1010-2752.

In this work, the antifungal activity of four natural extract essential oils was determined in vitro on three isolates of Fusarium spp (F2 and F5 of Fusarium solani (Martius) Appel & Wollenweber emend. Snyder & Hansen and F3 of Fusarium redolens Wollenweber), pathogens in the tomato (Solanum lycopersicum L.) crop in Cuba. The bioassay was performed as a completely randomized design using the method of filter paper disks inoculated with the oils placed in direct contact with the discs of the Fusarium isolates. The fungal radial growth was evaluated for up to 96 hours. The Casimon of anise (Piper auritum Kunth) oil produced complete growth inhibition of the isolates; meanwhile, the oil from the platanillo of Cuba (Piper aduncum subsp. ossanum (C. DC) Saralegui) showed to have a high fungistatic power. Melaleuca oil (Melaleuca quinquinervia (Cav) ST Blake showed little growth inhibition in the three isolates, whereas any of the isolates was inhibited by Citrus (Citrus sinensis L. Osbeck) at any of the concentration tested, which limits the possible use of these in the practice. The Casimon of anise oil was the most prominent, and it is recomended to be further nvestigated for its properties for the control of plan pathogens.
