Abstract

Four field studies were conducted over a 3-yr period (2011 to 2013) to determine the tolerance of four soybean cultivars to pyroxasulfone (89 and 178 g ai ha−1), flumioxazin (71 and 142 g ai ha−1), and pyroxasulfone + flumioxazin (160 and 320 g ai ha−1) applied either preplant incorporated (PPI), PRE, or at the soybean cotyledon stage (COT). When pyroxasulfone + flumioxazin was applied at 160 and 320 g ai ha−1, at the cotyledon stage soybean yield was decreased by 9 and 14%, respectively. The only other treatment that decreased soybean yield was pyroxasulfone (178 g ai ha−1) applied PPI; yield was decreased by 6% despite minimal injury and dry biomass reductions observed during the season. Soybean tolerance to pyroxasulfone or flumioxazin applied alone was generally similar and injury was less than with pyroxasulfone + flumioxazin. Similarly, herbicides applied PPI and PRE were less injurious to soybean than the COT timing. Results suggest that soybean is tolerant to PPI and PRE applications of pyroxasulfone + flumioxazin but COT applications should be avoided.

Se realizaron cuatro estudios de campo durante un período de 3 años (2011 a 22013) para determinar la tolerancia de cuatro cultivares de soya a pyroxasulfone (89 y 178 g ai ha−1), flumioxazin (71 y 142 g ai ha−1), y pyroxasfulone + flumioxazin (160 y 320 g ai ha−1) aplicados ya sea incorporados en presiembra (PPI), PRE, o en el estado cotiledonal de la soya (COT). Cuando se aplicó pyroxasulfone + flumioxazin a 160 y 320 g ai ha−1 en el estado cotiledonal, el rendimiento de la soya se redujo en 9 y 14%, respectivamente. El único otro tratamiento que disminuyó el rendimiento de la soya fue pyroxasulfone (178 g ai ha−1) aplicado PPI, en el cual el rendimiento se redujo 6% a pesar de que el daño y reducciones de biomasa seca observados fueron mínimos durante la temporada de crecimiento. La tolerancia de la soya a pyroxasulfone o flumioxazin aplicados solos fue generalmente similar y el daño fue menor que con pyroxasulfone + flumioxazin. Similarmente, los herbicidas aplicados PPI y PRE fueron menos dañinos a la soya que al aplicarse COT. Los resultados sugieren que la soya es tolerante a aplicaciones PPI y PRE de pyroxasulfon + flumioxazin, pero las aplicaciones COT deberían ser evitadas.
