| Abstract | ||||
| Sixteen pepper (Capsicum annuum L.) seed samples were collected from Alexandria markets and examined for the presence of seedborne fungi using the standard blotter and agar plate methods (ISTA, 1981). Observations revealed that Alternaria alternate; Aspergillus spp., Cladosporium herbarum, Colletotrichum capsici, Curvularia lunata, Fusarium oxysporum, F. semitectum, F. solani, Penicillium spp., Rhizopus sp., Rhizoctonia solani and Stemphyllium sp. were the most predominant fungi associated with pepper seeds. The standard blotter method was better than agar plate method as it detected 11 fungi compared to 8 fungi detected by the latter method. Pathogenicity tests revealed that some of the pepper seedborne fungi were capable to produce damping-off and wilt of the tested pepper cultivars. Seed infection levels of pepper with Fusarium oxysporum had significant effect on wilt incidence, for this reason it is recommended to use free seeds or with low infection levels to minimized wilt incidence. Culture filtrate either of Fusarium oxysporum or F. solani had reduced seed germination than that of F. semitectum. | ||||
