Thanks Trent.
I have already tried some h2o2 treatments, but not to the extent that you describe. If I try what you suggest, are you recommending a root soak with straight 3% h202, or a more dilute concentration? I dont want to risk burning the roots of an already stressed plant.
I have been treating with myco and other microbe innoculants. If I try any kind of anti fungal, I assume those will be nuked too. Thats actually one advantage I see in the h2o2 approach rather than other chems. The fact that it decomposes quickly into water means I can re-innoculate with beneficials right away.
Anyone else have good experiences with agressive h202 treatment like this?
Thanks.

When I did it, I used enough to completely drive all of the old stale water out of the pots. I had brought in my overwinters in the fall, waited until the last minute to haul them in before we had a hard frost, and it was raining. So they were SOAKED. That caused me lots of problems. The overwinters never used up the water in the pots, they wilted, they dropped leaves.. and then started getting fungus issues on top of all of that.
I went thermonuclear on them with H2O2. Figured it was a hail mary anyway, what the hell. In some of the 5 gallon pots I used as much as 5-6 quarts. I flushed out tons and tons of stinky water. The compacted soil bubbled back up and filled the pot. (It was pretty cool to watch). Just kept pouring and pouring the stuff in the soil until I ran out.
(Worth noting my wife and I cleaned out two dollar stores and the local walmart of H2O2 on this little adventure - I was dead set on trying to save those damn plants.)
The overwinters, within 2 days, sprung back to life and didn't have any further problems. Infected leaves eventually dropped off but the huge amounts of new growth was awesome.
I did the same thing on a smaller scale on in-the-dirt peppers in 2015 in an attempt to kill off septoria blight, that tomatoes had caught. THAT didn't work. Just wasted gallons of H2O2. I had to hand prune thousands of leaves until I got that septoria under control. Since it was in the soil, that pretty well ended me growing peppers or tomatoes again. I discontinued gardening for 3 years.. until I bought a farm..
Septoria showed up on the tomatoes my mother gave me as a birthday present, she'd got them at wal-mart. A week or so after they went in the dirt - everything else had been in for 2 weeks already - those tomatoes she got me started showing signs of septoria. Within another week, the tomatoes I grew from seed were showing signs. I tried cutting them back, eventually ripped the whole batch of them out of the ground, but it was too late. The peppers started showing it in an expanding radius from where those initial tomatoes went in the ground.
Since then I've vowed never to plant something I didn't grow from seed, myself.
ugh! Guess trial and error will lead to more experience for future! Maybe just use the straight promix until they get bigger and out of the 72 cells-->3" nursery pots? Thanks guys!
