| dc.description | Rice (Oryza sativa L.) is one of the most extensive crops in Ecuador, since it covers more than a third of the country's provisional product area. These weeds can be found between the limits of tolerance in rice production, since they cause direct and indirect damage due to the competition of light, water and nutrients in our crop. The objective of the research is to evaluate a mixture of post-emergence herbicides in rice cultivation. The investigation will be carried out in the area of Palmar, Babahoyo canton in the province of Los Ríos. The Ferón rice variety and treatments with herbicide mixtures (Fenoxaprop-p-ethyl), (Quinclorac + Cyhalofop-butyl), (Propanil), (2,4-D Amine + Picloram), (Pendimethalin) were used. The experimental design of complete randomized blocks was used, with 7 treatments, 4 repetitions, the comparisons of the means will be made with the Tukey test at 5% of statistical significance. For all statistical calculations, the Infostat and Excel computer tools will be used. Treatment 6 where the herbicides (Fenoxaprop – Ethyl) + (Quinclorac + Cyhalofop-butyl) + (Propanil) + (2,4-D Amine + Picloram) + (Pendimethalin) are mixed at doses of 700cc, 1lt, 1.5lt, 400cc, 2lt presented a greater control and efficiency when eliminating the populations that are regularly present in the rice crop at 40 days after planting with an average control of 95% and at 60 days it obtained an average of 100%. . | es_ES |

| dc.description.abstract | El arroz (Oryza sativa L.) es uno de los cultivos más extenso del Ecuador, ya que abarca más de la tercera parte del terreno de productos provisional del país. Estas malezas se pueden encontrar entre los límites de tolerancia en la producción de arroz, ya que provocan daños directos e indirectos por la competencia de luz, agua y nutrimentos en nuestro cultivo. El objetivo de la investigación es evaluar mezcla de herbicidas post emergentes en el cultivo de arroz. La investigación se llevará a cabo en la zona de Palmar, cantón Babahoyo en la provincia de Los Ríos. Se utilizó la variedad de arroz Ferón y los tratamientos con las mezclas de herbicidas (Fenoxaprop-p-etil), (Quinclorac + Cyhalofop-butyl), (Propanil), (2,4-D Amine + Picloram), (Pendimethalin). Se utilizó el diseño experimental de bloques completos al azar, con 7 tratamientos, 4 repeticiones, las comparaciones de las medias se efectuarán con la prueba de Tukey al 5% de significancia estadística. Para todos los cálculos estadísticos se utilizará la herramienta informática Infostat y Excel. El tratamiento 6 en donde se mezcla los herbicidas (Fenoxaprop – Ethyl) + (Quinclorac + Cyhalofop-butyl) + (Propanil) + (2,4-D Amine + Picloram) + (Pendimethalin) a dosis de 700cc, 1lt, 1.5lt, 400cc, 2lt presento un mayor control y eficacia al momento de eliminar las poblaciones que regularmente están presente en el cultivo de arroz a los 40 días después de la siembra con un control promedio de 95 % y a los 60 días obtuvo un promedio de 100 %. | es_ES |
