Most of the important pathogens found on the seed coat will stay there no matter how long you store the seeds but it does depend on How you store your seeds I would think.
Asking about how long some pathogens can remain in the soil is a totally different question. For the common foliage fungal pathogens it can be up to 5 years but you can get around that by turning the soil over completely with a shovel, not with a tiller, so the spores are buried deeply and less likely to be involved with what's called splashback infection if they were closer to the surface,'
I also know that Fusarium infested soil is a problem and in some cases such soils stay infested.
Bacterial Canker is found in the endosperm of the seed, not on the seed coat.
