Abstract
Antagonism between biocontrol agents Trichoderma viride, T. harzianum and T. hamatum against three phytopathogenic fungi: Fusarium solani, F. oxysporum and F. dimerum which cause damping-off on sugar beet cultivars in Egypt. In vitro, percentage reduction of T. viride was more than the other fungi for the untreated with Fusarium solani and F. oxysporum, while Trichoderma hamatum was effective antagonist for the control of F. dimerum. In vivo, T. viride was the most antagonist effective for untreated with F. solani (85%) survival plants, while T. hamatum was the most antagonist effective for the control of F.oxysporumand F. dimerum (87.5, 82.5) %survival plants. This result shows that Trichoderma spp. are very effective biocontrol agents against Fusarium spp. involved in sugar beet damping-off.
