Crenate broomrape (Orobanche crenata) is a parasitic plant.
Orobanche infestations can be devastating to crops and remove otherwise productive land from effective use for very long periods of time. Crenate broomrape is well known as a major constraint for faba bean, vetches and lentil, being of importance also on other grain and forage legumes.
