Our work is aimed at the identification of the integral parasitism (holoparasite) and the study of the genus of the plant named: (Cuscuta spp) in the north of Africa based on a discussion and a revision of all the studies that have been done on the plant in this region (Africa.) After adding the data, analyzing and comparing , we concluded that the plant (Cuscuta) is completely harmful and parasitic, and this parasitic phenomenon originated in North America., and it is for this reason that this kind of plant appeared in the north of Africa. Therefore, the damage of This parasitic plant can cause an imbalance in the physiological functions and wilting of neighboring plants. For the ways of combating this parasite, there are several, the most effective are chemical, preventive and active methods and the study of this plant is still limited and based on the threats of this parasite, on agricultural harvests and the discovery of other genera of this parasite at all times, which means that the fight against this harmful plant is still ongoing.
