Abstract

Field experiments were conducted in 2008, 2011, and 2012 to investigate the interaction between seeding system disturbance and PPI herbicides on rigid ryegrass control in wheat. Of the herbicides examined, prosulfocarb + S-metolachlor, and pyroxasulfone provided ≥ 70% control of rigid ryegrass, irrespective of seeding system. In contrast, trifluralin was the least-effective herbicide against rigid ryegrass and was particularly ineffective when used with single disc (10% control) relative to the triple-disc seeding system (80%) in 2012. Trifluralin consistently reduced wheat density when incorporated using single discs (46 to 59%) but not do so with the triple disc or double-shoot knife-point systems. Although there were large differences in crop establishment because of herbicide phytotoxicity, that did not always translate into large differences in yield because wheat was able to recover from reductions in plant density by increasing the spike number per plant. Pyroxasulfone caused no damage to wheat and appeared to be the most suitable PPI herbicide for use with single-disc seeding systems.

En 2008, 2011 y 2012, se realizaron experimentos de campo para investigar la interacción entre la perturbación causada por el sistema de siembra y el herbicida PPI en el control de Lolium rigidum en trigo. De los herbicidas examinados, prosulfocarb + S-metolachlor, y pyroxasulfone brindaron ≥70% de control de L. rigidum, independientemente del sistema de siembra. En contraste, trifluralin fue el herbicida menos efectivo contra L. rigidum, y fue particularmente inefectivo cuando se usó con el disco sencillo (10% de control) en relación con el sistema de triple-disco (80%) en 2012. Trifluralin redujo consistentemente la densidad del trigo cuando se incorporó usando discos sencillos (46 a 59%), pero esto no ocurrió con el triple-disco o con sistemas de doble cuchilla. Aunque hubo grandes diferencias en el establecimiento del cultivo debido a la fitotoxicidad de los herbicidas, esto no siempre se tradujo en grandes diferencias en rendimiento porque el trigo fue capaz de recuperarse de las reducciones en densidad de plantas al incrementar el número de espigas por planta. Pyroxasulfone no causó daño al trigo y pareció ser el herbicida PPI más adecuado para uso con sistemas de siembra de disco sencillo.
