Abstract

Winter wheat is the predominant crop in Oklahoma, but winter annual grasses are becoming increasingly difficult to control. Summer crop rotations have not been generally adopted; it was decided, therefore, to use winter canola in a crop rotation. However, very little is known about how well herbicides used in canola production will control the winter annual grasses found in Oklahoma wheat fields. Thus, an experiment was conducted at three sites, and repeated the following year, to determine the efficacy of trifluralin, quizalofop, clethodim, and glyphosate in canola production. The weeds evaluated in the experiment were Italian ryegrass, feral cereal rye, and volunteer wheat, along with two varieties of canola: a glyphosate-resistant variety and a conventional variety. All herbicides effectively controlled volunteer wheat. Feral cereal rye and Italian ryegrass varied in response to the herbicide treatments. Trifluralin followed by (fb) quizalofop and glyphosate fb glyphosate were effective on all target species across locations. Effective control of grass weeds was obtained in both conventional and glyphosate-resistant winter canola. Most herbicide treatments improved canola yield over the nontreated check. This experiment demonstrates that Oklahoma wheat producers can effectively rotate to canola to use other herbicides for control of problematic grassy weeds.

El trigo de invierno (Triticum aestivum) es el principal cultivo en Oklahoma, pero las gramíneas anuales de invierno se han vuelto cada vez más difíciles de controlar. Las rotaciones de cultivos en verano, en general no son comunes y por lo tanto, se tomó la decisión de utilizar canola (Brassica napus) de invierno como cultivo de rotación. Sin embargo, se sabe muy poco acerca de que tan bien los herbicidas usados en canola controlarían a las gramíneas anuales de invierno presentes en los campos de trigo de Oklahoma. Por esta razón, un experimento se implementó en tres sitios y se repitió el año siguiente para determinar la eficacia de trifluralina, quizalofop, clethodim y glifosato, en la producción de canola. La maleza evaluada en el experimento fue Lolium multiflorum, Secale cereale y T. aestivum, con dos variedades de canola, la resistente al glifosato y una variedad convencional. Todos los herbicidas controlaron efectivamente T. aestivum. S. cereale y L. multiflorum variaron en su respuesta a los herbicidas. Trifluralina seguido por (fb) quizalofop y glifosato fb glifosato fueron eficaces en todas la especies evaluadas en todos los sitios. Un efectivo control de la maleza de gramíneas se obtuvo en ambas canolas, la convencional y la tolerante al glifosato. La mayoría de los tratamientos con herbicidas mejoraron el rendimiento de la canola, en comparación al testigo no tratado. Este experimento demuestra que los productores de trigo de Oklahoma pueden rotar efectivamente a canola para utilizar otros herbicidas para el control de gramíneas problemáticas.
