I know its completely off topic but i got a couple of what i think are pseudomonas crown rots recently (rot starting at the base of the crown and working its way through the lower leaves and up, instead of starting at the top and working its way down... roots fine).

And i sprayed them good with 6% H202. It stopped the rot flat in its tracks, and since then it has also stopped the occasional spot. So i recommend it for a quick fix leaf spot killer.

I myself have been using h2o2 for about a week as a prevention in the new growth where the pb joins the leaf ....My dixie hummingbird makes a very deep joit there and I put a drop of it in once in a while to kinda keep stuf boiled out of it and then use a qtip to dry it.

Does h2o2 burn tender growth and need flused out after use?

OH and by the way I feel its not of topic by far if at all ----thanks

Even though I brought up the "vehicles" or "vases" I don't actually know where one would get them. I do know that when the do a placebo study of any topical drug, they use the identical vehicle with and without the drug, so they have to be available somewhere- pharmaceutical supply houses maybe?
But if you try to buy supplies that way, you might get visited by the DEA, FBI or ATF- or all 3

That's bases, not vases.

Flushing it out is not absolutely necessary, since the reaction that causes the fizzing just leaves 2 byproducts: water and oxygen. I don't think it damages tender growth as it's frequently used to cure crown rot (so often new tender leaves) and the reaction lasts only a few seconds.

Interestingly, plants under attack by microorganisms who recognize that they are being attacked will naturally produce h2o2 as part of a defense strategy called hypersensitive response (which is initiated by salicylic acid signaling in the plant). The cells that were breached by the pathogen essentially self distruct through the production of radicals and h2o2, halting the pathogen infection.

So if I hadn't any hydrogen peroxide available, could I water them with weak soluble aspirin to stimulate this response?
