Besides the advantages of soaking seeds to remove disease spores when starting them, Does anyone have any experience using Hydrogen Peroxide in other stages of the plants growth such as soil watering to promote oxygenation?

I have begun seed starting testing and now I'm testing the use of H2O2 in soil watering some of the new seedlings. Each morning after I water with it I can hear a slight fizzing sound coming from within the pot as the extra oxygen atom dissolves away from the water. So far the plants appear to be unaffected by its usage.

What dosage would be good to use in such applications?

Is H2O2 harmfull to mycorrhisal fungi?

I've used it to treat stem rot on a fruit.

In the past I used to treat PM with it but have now moved on to diluted 5% Peroxyacetic acid (hydrogen peroxide + vinegar)as it is supposed to be more effective it is also very cheap here as it has become widely used as a general farm disinfectant.

I also mixed it with milk to try treating PM leaves looked better.I found out after that H2O2 + Milk = Polymer (wiltpruf is a polymer).

Can't help you with the soil.

Here are some things I have found Russ, seems that some suggest that it might kill beneficial organisms in the soil though.

Russ,

I got a tip from Dr. Liggett earlier this year regarding the use of hydrogen peroxide.

He buys the high-powered stuff from beauty suppy places such as Sally's and cuts it down to around 6%. He then sprays the stem lightly with a fine mister and dusts it lightly with Captan without caking it in the end. I have yet to see a Liggett pumpkin with a stem defect of any kind.

He also suspends the main vine a couple of feet on either side of the stem with something very light such as panty hose to keep it straight and stress-free. As the pumpkin grows in height, he raises the main.

I was wondering more about if anyone had tried using it in irrigation water?

Russ - i've thought about it.

My main concern is having it oxidize off as soon as it hits the ground surface when it contacts the organic matter. I don't think it would do the roots any good in that case.

A few years ago I used calcium peroxide on one of my plants. I double dug, specifically trying to mix the powder in at least 6 inches deep. I had one of my best years then (2002), but I can't say that directly related to the peroxide.

I believe that a subterranean drip system would be the ideal delivery method. The O2 would then take more time to dissipate. You might even enjoy some anti-fungal effects.

I read an article sometime ago in one of the SNGPG newsletters about the chemical makeup of rain water.
The article said that rain contains Nitrogen and Hydrogen
Peroxide. I have wondered if a person could formulate pure rainwater what the benefit would be. And in peticular
how the and if the plants benefit frome the Hydorgen Peroxide....LB

I would think there is no such thing as pure rainwater. There is pure water, ie. distilled water, but as water falls, it is subjected to whatever is in the air around it, hence acid rain, etc.
