Abstract
Sesame seedling-rot and wilt diseases are considered of the most important diseases that affect yield and seed quality of sesame plants.
Laboratory experiments were carried out to study the effect of five Trichoderma spp. isolates on the linear growth (LG) of M. phaseolina and F. oxysporum. The antagonistic effect of T. harzianum, T. viride and T. hamatum against the two fungi showed clear suppression in (LG) by T. harzianum isolates (Tl, T2, T3 and T4) for the isolates of M. phaseolina (Ml, M5, M8 and M10), respectively. Greenhouse experiments showed that all antagonistic fungi were significantly effective in controlling disease incidence caused by M. Phaseolina on survival and healthy plants. The highest percentage of healthy plants was produced by Trichoderma harzianum; T2, followed by T. hamatum T10. For disease incidence caused by F. oxysporum. The highest percentage of healthy plants was produced by Trichoderma hamatum, T10 followed by T. viride T5 and T. harzianum, T3 compared to control treatment.
