I've only used sulfur as a fungicide and dust stored tubers and such. I'd probably spread the seeds on some newspaper for about a week before storing them. Dust half and leave the others alone. I'd store them in separate envelopes in a cool dry location. Good luck.

Karyn -

Thank You.. makes such good sense.. Got to ask though: what effect will laying them out on newspaper have... drying them out some?

Thanks again --

Deb.

If that are not completely dried and you store them you risk mold again.

Spreading them on the newspaper will allow them to dry some more. Since there's mold there might be residual moisture. In all likelihood they probably are completely dry but I'd do it to be on the safe side.

It sounds as if laying them on newspaper, and experimenting with some powder sulfur (for 1/2 or part of them) are my choices.
Thank you, chena and karyn... I much appreciate your input -
