Abstract
Se evaluó el efecto anti fúngico de la aplicación de cinco extractos vegetales: ortiga (Urtica dioica), manzanilla (Chamaemelum nobile), marco (Artemisia vulgaris), lavanda (Lavandula officinalis) y chamico (Datura ferox), a nivel de laboratorio para control de antracnosis (Colletotrichum acutatum) del tomate de árbol (Solanum betaceum), utilizando dos métodos de extracción (maceración y arrastre de vapor), en los resultados obtenidos, se observa diferencias estadística en el porcentaje de inhibición de crecimiento micelial del hongo, el tratamiento con extracto de lavanda obtenido por el método de arrastre de vapor, presentó la mayor eficacia para control de antracnosis (66.23%). Los demás tratamientos ensayados también presentó actividad contra el patógeno de la antracnosis, en el siguiente orden de inhibición: manzanilla (52.78 %), marco (21.63), chamico (24.14 %), ortiga (12.94), la capacidad de diversas especies de inhibir ciertas enfermedades fúngicas, asumiéndose al contenido diferente de metabolitos secundarios que tienen cada una de las especies vegetales, constituyendo en una alternativa de producción limpia, que reduzcan la utilización de pesticidas químicos para el control de las enfermedades fúngicas.
The antifungal effect of five plant extracts: nettle (Urtica dioica), chamomile (Chamaemelum nobile), frame (Artemisia vulgaris), lavender (Lavandula officinalis) and chamico (Datura ferox) were evaluated at laboratory level for control of anthracnose (Colletotrichum acutatum) of the tree tomato (Solanum betaceum), using two methods of extraction (maceration and steam trapping), in the results obtained, statistical differences were observed in the percentage of inhibition of mycelial growth of the fungus, the treatment with lavender extract obtained by the steam trapping method presented the greatest efficiency for anthracnose control (66.23%). The other treatments tested also showed effectiveness against the anthracnose pathogen in the following order of inhibition: chamomile (52.78%), frame (21.63), chamico (24.14%), nettle (12.94), the ability of various species to inhibit certain fungal diseases, taking into account the different content of secondary metabolites that have each of the plant species, constituting new clean production alternatives that reduce the use of chemical pesticides for the control of fungal diseases.
