| dc.description | The document details on the management of Fusarium wilt disease (Fusarium oxysporum f. Sp. Lycopersici) in table tomato cultivation. The fungus Fusarium oxysporum f. sp causes wilting of the plant and premature death of the crop, causing economic losses to farmers. Among the conclusions it is detailed that planting cultivars resistant to diseases, in order to lower the incidence in the plantations, caused by Fusarium oxysporum f. sp .; Foliar application of honey to husk tomato seedlings favored fruit production in the presence of Fusarium oxysporum. The foliar combination of silicon and honey decreased the severity of damage by Fusarium oxysporum; the enzymatic nature of the effect of F. oxysporumf. s p. lycopersici in tomato and indicate that the reduction of wilting in resistant plants could be due to the deactivation of the enzymes due to the effect of the catechins present in them; the main modes of action of T. harzianum isolates were parasitism and competition of nutrients and space, since they developed rapidly, surpassing the growth of F. oxysporum, preventing normal development and inhibiting its development by more than 50% and identified F. oxysporum as causative agents of tomato wilting and it was possible to differentiate the symptoms induced by each of these pathogens, which will allow a correct diagnosis of the organism causing the disease to be made, since the choice of a proper management method that can avoid severe damage to the crop. | es_ES |

| dc.description.abstract | El documento detalla sobre el manejo de la enfermedad Marchitez por Fusarium (Fusarium oxysporum f. sp. lycopersici) en el cultivo de tomate de mesa. El hongo Fusarium oxysporum f. sp provoca marchitez en la planta y muerte prematura del cultivo, causando pérdidas económicas a los agricultores. Entre las conclusiones se detalla que sembrar cultivares resistentes a enfermedades, a fin de bajar la incidencia en las plantaciones, provocadas por de Fusarium oxysporum f. sp.; la aplicación foliar de miel de abeja a las plántulas de tomate de cáscara favoreció la producción de frutos en presencia de Fusarium oxysporum. La combinación foliar de silicio y miel de abeja disminuyó la severidad de daño por Fusarium oxysporum; la naturaleza enzimática del efecto de F. oxysporumf. s p. lycopersici en tomate y indican que la reducción de la marchitez en las plantas resistentes podría deberse a la desactivación de las enzimas por efecto de las catequinas presentes en éstas; los principales modos de acción de los aislamientos de T. harzianum fueron parasitismo y competencia de nutrientes y espacio, ya que se desarrollaron rápidamente, superando el crecimiento de F. oxysporum, impidiendo el desarrollo normal e inhibiendo en más del 50% su desarrollo y se identificó a F. oxysporum como agentes causales del marchitamiento del tomate y se logró diferenciar la sintomatología inducida por cada uno de estos patógenos, la cual permitirá realizar un diagnóstico correcto del organismo causante de la enfermedad, pues de esto depende en mucho la elección de un método de manejo apropiado que pueda evitar daños severos al cultivo. | es_ES |
