We attempted to detect and assess the pathogenic potentials of the mycoflora causing wilt and root rot in pepper and to screen the antagonistic potentials of two medicinal plant-derived Trichoderma species (Trichoderma atroviride T32 and Trichoderma sp. N97) against the more pathogenic fungal pathogens. The taxonomic characterization revealed that the Fusarium spp. (56.9%), constituted of F. oxysporium f. sp. capsici (47.1%) and F. solani (9.7%) was the most distributed. Axenic soil infestation with the recovered pathogens successfully induced root rot, leaves chlorosis and root rot, resulting in 52% and 68.92% root stunting in sweet and hot pepper, respectively. The bioagents produced up to 64% inhibition of pathogens’ mycelia growth in confrontation assay, presumably by antibiosis. The ethyl acetate-based extracts from the Trichoderma spp. (10 mg/ml) completely lysed the Fusarium conidia and chlamidospores. The tested bioagents are no doubt promising biological control candidates against pepper wilt and root rot pathogens.
