Abstract

Field studies were conducted in 2008 and 2009 near Crowley, LA to evaluate the addition of a herbicide with soil-residual activity in mixture with imazethapyr applied very early POST followed by an application of imazethapyr or imazamox 2 wk after the initial application. Weeds evaluated included red rice, barnyardgrass, and alligatorweed. Weed control with treatments including a herbicide with soil-residual activity was equivalent to or higher than imazethapyr applied alone followed by imazethapyr or imazamox. Yield and economical returns were maximized with quinclorac or penoxsulam mixed with imazethapyr followed by imazethapyr or imazamox. The addition of quinclorac or penoxsulam proved to be beneficial in a total weed management program.

En 2008 y 2009 se realizaron estudios de campo cerca de Crowley, Louisiana para evaluar la adición de un herbicida con actividad residual en el suelo, mezclado con imazethapyr aplicado en pos-emergencia muy temprana seguido de una aplicación de imazethapyr o imazamox dos semanas después de la aplicación inicial. Las malezas evaluadas incluyeron Oryza sativa, Echinochloa crus-galli y Althernanthera philoxeroides. El control de las malezas con tratamientos que incluyeron un herbicida con actividad residual en el suelo fue equivalente o mayor al obtenido con imazethapyr aplicado por sí solo seguido por imazethapyr o imazamox. El rendimiento y las utilidades netas se maximizaron con quinclorac o penoxsulam mezclado con imazethapyr seguido de imazethapyr o imazamox. La adición de quinclorac o penoxsulam probó ser benéfica en un programa integral de manejo de malezas.
