Summary The broomrape ( Orobanche crenata Forsk) susceptibility to glyphosate applied on faba‐bean ( Vicia faba L.) as affected by the parasite growth stages at the time of application was studied under field conditions. Glyphosate treatments delayed O. crenata emergence. Single glyphosate application to faba‐bean infected with O. crenata predominantly at the stage (a) (small nodule) and (b) (nodules with initial vestigial roots) resulted in a moderate to low control. When the stages (c) (shoot bud already visible) or (d) (shoot and vestigial roots well developed) were the predominant stages, an excellent control was achieved with a single glyphosate application at 60 g ha −1 . Increased development stages, with the shoot emerged from the shoot bud, decreased its susceptibility to glyphosate.
