Any info on hydrogen peroxide?

I have seen studies showing that diluted hydrogen peroxide can help some crops germinate. Is this true for tomatoes?

I use it straight out of the bottle,especially for old tomato seeds.
They even have peroxide in spray type bottles to make the job easier.
I save tomato seeds on paper plates and just spray them when planting time comes.
When peroxide decomposes it changes to h2o anyway.

I use the stuff too, always. I spray my seeds and also when I sow the seeds, I moisten my soil with a mix of water and hydrogen peroxide. Not only helps with germination, but helps against any bad fungal spores that might be on outside of seeds.

It also kills fungus gnat eggs, good stuff all around! Cheap too!

3% diluted 2:1 makes an excellent preventative spray for fungal problems. I had black mold from having whiteflies, and peroxide killed that mold right away.
