Abstract

Greenhouse and field experiments were conducted to determine whether PRE-applied ethofumesate increased POST spray retention and weed control with glyphosate. In greenhouse studies, ethofumesate was applied PRE at rates from 0 to 224 g ai ha−1 followed by POST treatment with either water or glyphosate (840 g ae ha−1) to which a red dye had been added. Plants were immediately washed and spray retention determined spectrophotometrically. Common lambsquarters retained more glyphosate solution compared to water, regardless of PRE ethofumesate rate. Increasing the rate of PRE ethofumesate increased the POST spray retention of both water and glyphosate. PRE application of ethofumesate increased POST spray retention of water by 114% and glyphosate solution by 18% compared to no ethofumesate treatment as determined by nonlinear regression. Ethofumesate rates of 90 g ha−1 increased POST spray retention to at least 95% of the total observed response. In field studies, common lambsquarters, redroot pigweed, and hairy nightshade densities were all reduced by ethofumesate, although the duration of ethofumesate effect varied by species and ethofumesate application timing. PRE ethofumesate had no significant effect on hairy nightshade density until after POST glyphosate was applied, whereas common lambsquarters densities were most affected by PRE ethofumesate early in the season. Late-season redroot pigweed density was reduced by ethofumesate regardless of application timing.

Se realizaron experimentos de campo y de invernadero para determinar si ethofumesate aplicado PRE incrementó la retención de aplicaciones de glyphosate POST y el control de malezas. En los estudios de invernadero, ethofumesate fue aplicado PRE a dosis de 0 a 224 g ha−1 seguidos de tratamientos POST con agua o glyphosate (840 g ae ha−1) a los cuales se les había agregado un colorante rojo. Las plantas fueron lavadas inmediatamente y la retención fue determinada espectrofotométricamente. Chenopodium album retuvo más glyphosate al compararse con agua, sin importar la dosis PRE de ethofumesate. Al incrementarse la dosis PRE de ethofumesate se aumentó la retención de las aplicaciones POST de agua y glyphosate. La aplicación PRE de ethofumesate incrementó la retención de agua POST en 114% y la de glyphosate en 18% en comparación al tratamiento sin ethofumesate, como se determinó usando regresiones no lineales. Dosis menores a 90 g ha−1 de ethofumesate incrementaron la retención de aplicaciones POST al 95% del total de respuestas observadas. En los estudios de campo, las densidades de C. album, Amaranthus retroflexus y Solanum sarrachoides fueron todas reducidas por ethofumesate, aunque la duración del efecto de ethofumesate varió según la especie y el momento de aplicación de ethofumesate. Ethofumesate PRE no tuvo ningún efecto en la densidad de S. sarrachoides hasta después de que se aplicó glyphosate POST, mientras que las densidades de C. album se vieron más afectadas por ethofumesate PRE, temprano en la temporada. La densidad de A. retroflexus, tarde en la temporada, fue reducida por ethofumesate sin importar el momento de aplicación.
