Abstract
Seed-borne fungi of bean are a serious problem worldwide causing damping-off and wilt diseases on common bean (Phaseolus vulgaris L.) plants. Several pathogenic fungal were isolated from seed samples collected from commercial markets in Egypt (Pronco, Nebraska, Giza 3, Giza 6 and Tema). Fusarium oxysporum and Fusarium solani were the common fungi isolated from seeds followed by Alternaria sp., Rhizoctonia solani, Helminthosporium sp. and Penicillium spp. Pathogenicity test indicated that, F. oxysporum and R. solani isolates were the most fungal isolates significantly induced damping off on bean plants. Bean seeds treated with peppermint oil caused a highly reduction in the infection and reduced fungal transmission from seeds to seedlings. Furthermore, vigor of bean seedlings raised from the treated seeds was better than that developed from the untreated ones which was reflected in the improved properties of the plant and increased the crop in the future.
