Determinación de la concentración óptima de aceite esencial mentha spicata l. (hierbabuena) en la inhibición del fusarium sp y alternaría sp presentes en dos variedades de lycopersicon esculentum m. (tomate) en Quevedo, 2016

Inhibition of fusarium and alternaria present in two varieties of Lycopersicon esculentum M. (tomato) where it determined the optimal concentration of essential oil Mentha spicata L. One of the main causes of decomposition of the tomato is in postharvest, for The presence of fungi that develop, not only in the superficial part to have several days exposed to the medium without any conservation treatment. The objective of this investigation is to determine the optimal concentration of essential oil of Mentha spicata L. in the inhibition of Fusarium sp and Alternaria sp present in two tomato varieties, resulting in a high antiphygetic potential in all concentrations inhibitory minimal prolonged life Useful of the raw material. The research was carried out in the laboratories of Microbiology and Molecular Biology of Quevedo State Technical University. For this, an investigation was proposed in which 12 treatments and 3 repetitions with essential oil concentrations of 0.5%, 1.5% and 2.5% were involved. From this, radial growth and percentage of spore inhibition were determined. With respect to the statistical analysis, a completely randomized block design with factorial arrangement A * B * C and 3 replications were used, considering factor A (essential oils types of Mentha spicata L. Extracted in the laboratory and commercial), factor B (Concentrations Of essential oils of 0.5%, 1.5% and 2.5%) and factor C (phytopathogenic fungi). In the evaluation of treatments for radial growth there was no significant difference resulting in 100% inhibition. With respect to the evaluation of inhibition of spore growth, as well as radial growth in all factors no significant difference was found inhibiting at 100%.
