Resumen
La investigación se efectuó en el cantón Daule, provincia del Guayas. Objetivos: 1) determinar la combinación de herbicidas que presente la mejor eficacia para el control de malezas en el cultivo de arroz; y, 2) realizar un análisis económico de los tratamientos estudiados. Se utilizó la variedad de arroz INIAP-14. Los factores estudiados fueron: herbicidas graminicidas, y herbicidas hoja ancha y ciperáceas. Conclusiones: la menor población de Leptochloa filiformis se obtuvo con las combinaciones siguientes: Checker (350 g/ha) + Aura (750 mL/ha); Basagran M-60 (1 L/ha) + Aura; y, Ally (15g/ha) + Designee (100 mL/ha). La menor población de Echinochloa colonum se obtuvo con el tratamiento Aura + Ally. La mejor eficacia para el control de las malezas Ciperáceas y Clavos de agua la tuvo el tratamiento con Designee + Checker. Los tratamientos que lograron mayor rendimiento fueron Designee + Ally, seguido por el tratamiento Designee + Basagran M-60. El mayor beneficio neto se lo alcanzó con la combinación Designee + Ally.
The research was conducted in the canton Daule, Guayas province. Objectives: 1) determine the herbicide combination offering the best efficacy for weed control in rice cultivation; and 2) an economic analysis of the treatments studied. Rice variety INIAP-14 was used. The factors studied were: graminicides herbicides, and sedges and broad leaf herbicides. Conclusions: the population under Leptochloa filiformis was obtained with the following combinations: Checker (350 g / ha) + Aura (750 mL / ha); Basagran M-60 (1L / ha) + Aura; and Ally (15g / ha) + Designee (100 mL / ha). The population under Echinochloa colonum was obtained with the Aura + Ally treatment. The best effectiveness in controlling weeds and sedges nails water treatment had Designee + Checker. Treatments that higher yields were achieved Designee + Ally, followed by designee + Basagran M-60 treatment. The largest net profit it reached with the Designee + Ally combination.
