The study was conducted on one season old vegetable seed, stored at room temperature at local seed dealer. Primarily, the samples were collected from Allama lqbal Town grain market which deals with the urban customers for fresh vegetable but circle of seed trade is expanded to adjacent districts. Initial isolations were made from 1% NaOCI treated and untreated seeds to distinguish between surface contaminants and seed borne fungi. According to ISTA standards 1996: seed health; (shape, size and 100 seeds uniformly weight), fungal association and performance; (cold test for germination, root shoot length, dry and fresh weight) were performed. Alternaria alternata, and Rhizopus sp. were isolated from treated and untreated stored seeds but the frequency of pathogens was less in treated seeds. Pathogens reduced germination, seedlings and growth rate of Spinach. As vegetables are important food stuff for daily use and not much work has been done regarding production technology of vegetable in Pakistan therefore, there is need for further studies in this dimension.
