Abstract
The parasitic weed striga is a major pest of cereals in the northern Ethiopian highlands. Striga has been a pest in traditional cropping systems for many years (Richard and others 1982). However, because traditional cropping systems involved prolonged fallow, crop rotations and mixed cropping, the parasite populations were kept at tolerable levels (Ogborn 1987). With increasing demographic pressure, striga infestation has gradually increased and become a threat to food production in Ethiopia (Delft and Stroud 1992, Parker 1992, Sherif and Mulatu 1992). The low and erratic rainfall conditions found in the northern regions of Ethiopia have also contributed to increased striga incidence.
