In: Journal of Agricultural Research Tanta Univeristy 2002.v.28(1)Summary: Soil samples collected from the rhizosphere of healthy tomato and pepper plants resulted in isolation of 45 bacterial isolates and 12 fungal isolates exhibiting marked antifungal activity against Fusarium oxysporum f. sp. Lycopersici, Rhizoctonia solani. Fusarium solani, and Pythium aphanidermatum the causal fungi of wilt and root rot to tomato and pepper plants. These biocontrol agents belong to Bacillus spp., Pseudomonas spp. as bacterial antagonists as well as Actinomyctes isolates, while fungal isolates belonged to Trichoderma spp., Gliocladium spp., Myrothecium spp., Paecilomyces spp. and Geotrichum spp. Among these antifungal antagonists Trichoderma harzianum. Gliocladium virens, Pseudomonas fluorescens. Bacillus subtilis and an Actinomycete sp. proved to have high potential effect against the tested pathogens.
