Efecto de aceites esenciales en emulsión en la antibiosis de hongos patógenos en condiciones de laboratorio, en la Universidad Técnica de Cotopaxi 2022-2023”.

Botrytis spp. and fusarium spp. are pathogenic fungi that infect more than 500 plant species causing productive and economic losses worldwide, attacking crops at different stages of plant development. The present research project was developed in the laboratory of the Cotopaxi Technical University whose objective was to evaluate the effect of essential oils in emulsion on the antibiosis of pathogenic fungi for which two concentrations were used at 25%, 50%, and including the control at 0%, a completely randomized design (DCA), with factorial arrangement (AxBxC), with twelve treatments and four repetitions. The experimental units were Petri boxes with PDA (Papa Dextrose Agar) where the purified fungi were inoculated in a diameter of 5.72 mm, then applying 0.25 ml of the essential oils in emulsion were applied and the radial growth of the fungi was evaluated every 24 hours for 8 days. The chemical composition analysis of the oils under study was conducted by gas chromatography. From the results obtained, we determined that the compounds with the highest presence were (Trans-Anetol 75.88%) in lavandula officinalis and (L-Borneol 22.02%) in Anethum graveolens. The essential oil that presented the least radial growth was Anethum graveolens, at 50% concentration on fusarium spp, with an average of 0.93 mm, followed by Botrytis spp. with the essential oil of Anethum graveolens with an average of 1 mm in diameter. It was possible to corroborate that the emulsified AEs do have an antibiosis effect by controlling the radial growth of the fungi.
