Abstract
Potato, one of the most important vegetable crops, is feeding the growing global population. It has an enormous economic outlet however; fungal and bacterial pathogens associated with seed tuber cause huge losses in its production. Planting healthy seed potatoes is a key factor in maximizing the production of potatoes for consumption or processing. In this study, the presence of different pathogenic fungi and two pathogenic bacteria (Clavibacter michiganensis subsp. sepedonicus that cause ring rot of potato and Salmonella sp., (a notorious human pathogenic bacterium) in imported seed potato varieties (Asterix, Ultra and Karuda) and four local varieties (Asterix, Lady Rusetta, Qasur and Mozika) were determined. Among highly plant pathogenic fungi, Fusarium solani (8-23%) and Rhizoctonia solani (9-13%) were associated with imported tubers, while Fusarium oxysporum (12-20%) and, R. solani (8-17%) were isolated from local seed tubers. Clavibacter michiganensis subsp. sepedonicus and Salmonella spp., were detected in all potato tubers examined. Association of highly pathogenic fungi and bacteria with seed tubers is a serious issue and needs further investigation
