Echinochloa species control in maize (Zea mays L.) with sulfonylurea herbicides applied alone and in mixtures with broadleaf herbicides

► Rimsulfuron, nicosulfuron, and foramsulfuron were evaluated on Echinochloa oryzoides and Echinochloa phyllopogon. ► Nicosulfuron provided the greatest control of both species irrespective of growth stage. ► Co-application with dicamba or MCPA provided lower efficacy than the single applications. ► Co-application with sulcotrione improved the efficacy of rimsulfuron and foramsulfuron. ► Co-application with mesotrione did not affect the efficacy of the sulfonylurea herbicides.
