Resumen
La presente investigación se desarrolló en el predio Eldelira, ubicada en la vía Daule-Santa Lucia, Rcto. Fátima, cantón Santa Lucia: Los objetivos específicos fueron: 1) Evaluar dos dosis de Trichoderma sp mas dos dosis del fungicida orgánico Timorex sobre la incidencia y severidad de patógenos en el cultivo de tomate; 2) Determinar el mejor tratamiento sobre la severidad de enfermedades en el cultivo de tomate y 3) Realizar el análisis de presupuesto parcial de los tratamientos.
Se empleó el diseño de bloques completamente al azar con seis repeticiones y cinco tratamientos, Los tratamientos fueron dos dosis de Trichoderma 1 y 1.5 L/ha más dos dosis de Timorex 1 y 1.5 L/ha y un testigo absoluto. Se evaluaron las siguientes variables: incidencia y severidad de enfermedad y se expreso en porcentaje, altura de planta (cm), rendimiento (kg/ha), número total de frutos/planta.
De acuerdo a los resultados obtenidos se concluyo: 1) que en los tratamientos de Trichoderma con 1 L/ha y 1.5 L/ha y Timorex 1 L/ha no presentaron incidencia de enfermedades. Los tratamientos de Timorex 1.5 L/ha y testigo absoluto presentaron incindencia de Ralstonia solanacearum en el cultivo de tomate cherry; 2) El mejor rendimiento fue con el tratamiento de Trichoderma 1 L/ha con 34206.35 kg/ha y 3) El análisis económico de los tratamientos indica que el tratamiento de Trichoderma 1 L/ha tuvo la mejor la tasa de retorno marginal con 5507.38%.
The present research was carried out in the Eldelira estate, located in the Daule-Santa Lucia road, Rcto. Fatima, canton Santa Lucia: The specific objectives were: 1) To evaluate two doses of Trichodermasp plus two doses of the organic fungicide Timorex on the incidence and severity of pathogens in the tomato crop; 2) Determine the best treatment on the severity of diseases in the tomato crop and 3) Carry out the partial budget analysis of the treatments. The treatments were two doses of Trichoderma 1 and 1.5 L / ha plus two doses of Timorex 1 and 1.5 L / ha and an absolute control. The following variables were evaluated: incidence and severity of disease and expressed as percentage, plant height (cm), yield (kg / ha), total number of fruits / plant. According to the results obtained, it was concluded: 1) that in the treatments of Trichoderma with 1 L / ha and 1.5 L / ha and Timorex 1 L / ha did not present disease incidence. The treatments of Timorex 1.5 L / ha and absolute control presented incineration of Ralstonia solanacearum in the cultivation of cherry tomato; 2) The best performance was with the treatment of Trichoderma 1 L / ha with 34206.35 kg / ha and 3) The economic analysis of the treatments indicated that the treatment of Trichoderma 1 L / ha had the best marginal return rate with 5507.38%.
