Other disinfectants that can be used on seeds -- up to the point of germination but not after -- include ordinary drugstore hydrogen peroxide solution (3%) diluted down anywhere from 2:1 to 10:1 or hypochlorite laundry bleach (sodium hypochlorite, ca 5%) diluted about 10:1 to 20:1 with tap water. The more dilute solutions can be used longer, when soaking seeds in disinfectants.
