Sometimes you get seeds that are known to be infected with a fungus or virus. i got a notice of this from the USDA ARS-Grin seed bank with a few seeds and they were recommending soaking with TSP. Soaking with H2O2 will work as well if soaked overnight.
So no I just soak them all as a matter of course.
Potassium Nitrate, KNO3, Salt Petre is the only ingredient in Spectracide stump remover. You can get it in 1lb bottles at Lowes for $8.00 approx You only need to mix it at 1gr per 99mL of water. Why 99mL of water, you ask? 1mL of water weighs 1gr. So to make a 1% solution you need 1gr of KNO3 to 99gr-mL of H2O.
