Pot experiments were designed to study the effect of three antagonistic fungi (Trichoderma harizianum, T. koningii and Trichorus spirales) and three organic amendments, German chamomile leaves (Matricaria chamomilla), garlic cloves (Allium sativum) and bakain leaves (Millia azederach) to control Orbanche crenata on faba bean plants. T. harizianum gave the best results in controlling O. crenata. It decreased the number and dry weight of Orobanche spikes. T.kaningii and T. spirales did not affect the growth of O. crenata on faba bean plants. Among the tested plants amendments garlic cloves gave the best result to control O. crenata. According to these results the authoress suggest that T. harizianum and garlic cloves could be used to minimize O. crenata plants on faba bean plants.
