Powdery Mildew- Safe to harvest seeds?

Hello all, Its almost seed saving time, but my Zinnias have started to come down with powdery mildew. Im about to try the Milk Spray trick, but will the seeds be spore-filled? destined to spread mildew wherever they go?

I know fermentation is often done on tomato seeds to kill off pathogens, any treatments for these?
