Abstract

A study was established to evaluate interactions between imazamox at 0 and 44 g ai ha−1 mixed with propanil at 0, 1,120, 2,240, 3,360, and 4,480 g ai ha−1 for the control of red rice and barnyardgrass. Blouin's Modified Colby's procedure was used to test for interactions. At 7 d after treatment (DAT), a synergistic response occurred for red rice treated with imazamox at 44 g ha−1 mixed with propanil at 3,360 and 4,480 g ha−1 by increasing expected control of 62% to an observed control of 67 and 75%, respectively, and the synergistic response continued across all evaluations through 49 DAT. No antagonism occurred for any imazamox plus propanil mixture for red rice control. An antagonistic response was shown for barnyardgrass control with imazamox at 44 g ha−1 mixed with any rate of propanil, at 7 DAT. However, imazamox plus propanil at 4,480 g ha−1 resulted in a neutral response at 14 through 49 DAT. Rice treated with imazamox plus propanil at 4,480 g ha−1 plus imazamox resulted in a yield of 6,640 kg ha−1. The synergistic response observed for red rice control with a mixture of imazamox plus propanil can benefit producers by increasing control of red rice, and this mixture contains two different modes of action that can be part of an overall resistance management strategy.

Se estableció un estudio para evaluar interacciones entre imazamox a 0 y 44 g ai ha−1 mezclado con propanil a 0, 1,120, 2,240, 3,360, y 4,480 g ai ha−1 para el control de arroz rojo y Echinochloa crus-galli. El procedimiento modificado Colby y Blouin fue usado para evaluar las interacciones. A 7 d después del tratamiento (DAT), ocurrió una respuesta sinérgica en el arroz rojo tratado con imazamox a 44 g ha−1 mezclado con propanil a 3,360 y 4, 480 g ha−1 al incrementarse el control esperado de 62% a un valor observado de 67 a 75%, respectivamente, y la respuesta sinérgica continuó en todas las evaluaciones hasta 49 DAT. No ocurrió antagonismo para ninguno de las mezclas de imazamox más propanil en el control de arroz rojo. Se demostró una respuesta antagónica en el control de E. crus-galli con imazamox a 44 g ha−1 en mezcla con cualquier dosis de propanil, a 7 DAT. Sin embargo, imazamox más propanil a 4,480 g ha−1 resultaron en una respuesta neutral entre 14 y 49 DAT. El arroz tratado con imazamox más propanil a 4,480 g ha−1 más imazamox resultó en un rendimiento de 6,640 kg ha−1. La respuesta sinérgica observada para el control de arroz rojo con una mezcla de imazamox más propanil puede beneficiar a los productores al incrementar el control del arroz rojo. Además, esta mezcla contiene dos modos de acción diferente que pueden ser parte de una estrategia general de manejo de resistencia a herbicidas.
