I know that there is a way to remove the chance of virus spores( septoria)on seeds by exposing them to hot water, How long?? What Temperature??

The chance of the spores being on the seeds is very low in the first place - septoria lives soil and thrives in moist conditions. It really isn't necessary to try to sterilize the seeds. Solarizing the soil is a much better idea. Hot water tends to cook things, and a cooked seed is a dead one.
