The carrot (Daucus carota L.) plays important socio-economic role in Morocco. Recently, frequent attacks by the parasitic plant Orobanche crenata has been reported and the infestation is increasingly observed in recent years causing huge damages. The results of study show that the parasitic weed attacks reduced root weight, root length and root diameter in carrot.Average reduction was 19.98, 20.04 and 9.10%, respectively. Furthermore, O. crenata affects the end-quality of carrot roots. This causes total yield decrease resulting in significant economic losses and thus reducing growers incomes.Total yield losses dues to O. crenata infestation ranged from 21 to 27 t/ha corresponding to monetary values of about 2600 and 3400 USD ha−1. To overcome this situation, there is an urgent need for effective control methods to limitthe infestation and reduce the losses.
