Abstract

In the Pacific Northwest (PNW), feral rye is a predominant winter annual grass weed in the low-rainfall region where a winter wheat–summer fallow rotation has been practiced for more than 130 yr. Recently, producers began including winter canola in their rotation, which provides additional herbicide options to control feral rye. A 3-yr study was conducted in Washington to determine the efficacy of clethodim, quizalofop, and glyphosate on feral rye control and winter canola yield. During the first year of the study herbicides were applied in the spring, and they increased canola yield and decreased feral rye biomass, density, and seed production similarly when compared with the nontreated control. During the last 2 yr of the study, split applications of quizalofop and glyphosate were the most effective treatments for controlling rye (> 95%) and increasing canola yield. In general, clethodim was less effective than both quizalofop and glyphosate in controlling feral rye. Results from this study indicate that quizalofop in conventional or glyphosate-resistant winter canola and glyphosate in glyphosate-resistant winter canola can effectively control feral rye.

En el Pacífico Noroeste, el centeno silvestre es una gramínea anual de invierno, predominante en la región de baja precipitación donde la rotación de trigo de invierno-barbecho de verano ha sido practicada por más de 130 años. Recientemente, los productores empezaron a incluir colza en su rotación, la cual brinda opciones de herbicidas adicionales para el control de centeno silvestre. Se realizó un estudio durante 3 años en Washington para determinar la eficacia de clethodim, quizalofop, y glyphosate para el control de centeno silvestre y el efecto de estos sobre el rendimiento de la colza de invierno. Durante el primer año del estudio, se aplicaron herbicidas en la primavera, y estos aumentaron el rendimiento de la colza y disminuyeron la biomasa, la densidad, y la producción de semilla del centeno silvestre en forma similar al testigo sin tratamiento. Durante los últimos dos años del estudio, las aplicaciones divididas de quizalofop y glyphosate fueron los tratamientos más efectivos para el control de centeno silvestre (>95%) y para aumentar el rendimiento de la colza. En general, clethodim fue menos efectivo que quizalofop y glyphosate para el control de centeno silvestre. Los resultados del estudio indican que quizalofop en colza de invierno convencional o resistente a glyphosate, y glyphosate en colza de invierno resistente a glyphosate pueden ser efectivas para el control de centeno silvestre.
