摘要：

Isolation trials from rotted sugar-beet roots collected in Egypt (Kafr El-Shikh governorate) yielded: Alternaria spp.; Mucor spp.; Fusarium spp., F. conglutinans, F. solani; Phoma (Pleospora) betae; Pythium debaryanum; Rhizoctonia solani; Sclerotium bataticola; Sclerotium rolfsii (the sclerotial state of Athelia rolfsii) and Trichoderma harzianum. All the isolated fungi were pathogenic except the antagonistic fungus, i.e. T. harzianum. The efficiency of Trichoderma as a biocontrol agent against fungi causing damping-off and root-rot was investigated in pot and field experiments. T. harzianum caused a great reduction in the infection level of damping-off and root-rot diseases, and resulted in increased root weight both in pot and field experiments during two successive growing seasons.
