Abstract

Due to the limited availability of selective herbicides to control Sumatran fleabane after soybean emergence, it is essential to develop new options that provide effective control prior to planting. A new herbicide formulation containing diclosulam+halauxifen-methyl was evaluated for effectiveness at two Sumatran fleabane plant heights (5 to 10 cm, and 10 to 50 cm) and for soybean selectivity when applied at 7 or 3 d before planting. Combined results from the two sites showed that diclosulam+halauxifen, applied either alone or in a tank mixture with glyphosate, and the tank mixture of diclosulam+2,4-D amine+glyphosate are effective at all rates tested to control Sumatran fleabane in preplant applications. Crop response was observed with applications 7 days before planting at only one of the sites. A rate-dependent crop response was observed for pre-plant applications performed 3 days before soybean planting. However, crop yield was not significantly affected for either timing across all rates. All rates tested of diclosulam+halauxifen in this study were considered safe to soybean.

Debido a la limitada disponibilidad de herbicidas selectivos para el control de Conyza sumatrensis después de la emergencia de la soja, es esencial desarrollar nuevas opciones que brinden un control efectivo antes de la siembra. Una nueva formulación de herbicidas que contiene diclosulam+halauxifen-methyl fue evaluada para determinar su efectividad para el control de C. sumatrensis a dos alturas de planta (5 a 10 cm y 10 a 50 cm) y su selectividad en la soja, cuando se aplicó a 7 ó 3 d antes de la siembra. Los resultados combinados de dos sitios mostraron que diclosulam+halauxifen, aplicado solo o en mezclas en tanque con glyphosate, y la mezcla en tanque de diclosulam+2,4-D amine+glyphosate son tratamientos efectivos para el control de C. sumatrensis en aplicaciones en pre-siembra. Se observó una respuesta del cultivo con aplicaciones a 7 días antes de la siembra en solamente uno de los sitios. Una respuesta del cultivo dependiente de la dosis fue observada para aplicaciones en pre-siembra realizadas 3 días antes de la siembra de la soja. Sin embargo, el rendimiento del cultivo no fue afectado significativamente por ninguno de los momentos de aplicación al promediarse todas las dosis. Todas las dosis evaluadas de diclosulam+halauxifen en este estudio fueron consideradas seguras en la soja.
