After not being able to find the information I need, I did my own experiement and will share the results with everyone.

Q: Is Hydrogen Peroxide at 3% safe for leaves?

I found a male plant and decided to use it as my test subject.

I put 200 mL of 3% H2O2 in a sprayer and
very generously drenched the whole plant.
There was no visible "fizzing" of the H2O2 on plant
Ten minutes after application, plant was dry.

Now, let's see what happens

If you have an infection in your mouth. They require you to swish and gargle 3%. Spit not swallow.

Is it necessary for me to drink my own urine? Probably not, but it’s sterile and I like the taste.

But I love hp for all kinds of purposes in the lab. Kill insect larvae in the roots, spray to kill any mold on top of medium or pot, clean up tent after PM, I could go on.

Ive used it as a root drench in coco a few times to kill some stuff, i usually dilute it 4:1 with distilled water. Is this to say i might not have to dilute it?? I still get the fizzies even when it's diluted.

Great looking plants BTW

You can spray 3% into your mouth and be perf fine. If it is ok to put it in your mouth you can put it on the plant...to an extent haha.

Yes you can because humans have emzymes in their cells that prevent H202 from doing damage.
Plants, insects and molds do not have these emzymes and therefore H2O2 can damage them.

What is the difference in price between H2O2 and Chlorhexidine gluconate ?

My experiment was on leaves and not on roots.
To test if I can use it to kill powdery mildew or other things without harming plant.
Someone else will need to do an experiment with H2O2 for root usage.

You can thank God or Mother Nature since I am a minimalist - that is I do the basics

The problem with H2O2 is it is extremely fugitive to both water and light. That extra Oxygen molecule pops off almost immediately in the sun. So essentially of course it's not damaging them because you sprayed them with water. Last time I looked water won't kill much of any of our pests. That's why H2O2 comes in dark bottles.

I use Marrone Regalia. If you're organic it is too. It's from a Reynoutria sp. (I'm not organic).

About the only thing I use H2O2 for is a rescue when I've over watered a soil plant. (I have a Kaffir Lime that was in soil). Good luck and that plant is lovely looking.
