Abstract

A study was conducted in summer fallow fields near Davenport, WA, and Pendleton, OR, in 2007 and 2008 to evaluate the POST weed control efficacy of herbicide treatments applied with a light-activated, sensor-controlled (LASC) sprayer compared to the broadcast application of glyphosate. The LASC application of glyphosate alone (at all rates) and in mixture with pyrasulfotole plus bromoxynil or 2,4-D had weed control (≥ 88%) and dry weight (≤ 6% of control) similar to the broadcast application of glyphosate across locations and years. Tumble pigweed and prickly lettuce control with bromoxynil, 2,4-D, or carfentrazone plus dicamba, was 12 to 85% less than glyphosate applied alone with LASC or broadcast sprayer. Overall, none of the tested alternate herbicides was promising enough to replace glyphosate under present conditions.

En 2007 y 2008 se llevó al cabo un estudio en campos de barbecho en verano, cerca de Davenport, WA y Pendleton, OR, para evaluar la eficacia del control post-emergente de malezas con herbicidas aplicados con un aspersor controlado y activado por un sensor de luz en comparación con la aplicación de glifosato con un aspersor convencional. Las aplicaciones de glifosato solo (a todas las dosis) y mezclado con pyrasulfotole más bromoxynil o 2,4-D con el aspersor controlado y activado por un sensor de luz, obtuvieron un control de malezas (≥ 88%) y peso seco (≤ 6% del control) similar a la aplicación de glifosato con el aspersor convencional en todas las localidades y años. El control de Amaranthus albus y Lactuca serriola con bromoxynil, carfentrazone más dicamba o 2,4-D, fue 12 a 85% menor que con glifosato aplicado solo con el aspersor controlado y activado por un sensor de luz o el convencional. En general, ninguno de los herbicidas alternos probados fue lo suficientemente prometedor para reemplazar al glifosato bajo las condiciones actuales.
