I literally just bought some Cleary's 3336 last week, as I've had some fungus problems with a few plants and was getting a bit worried. I got the powdered version, though you can get the liquid. The powder mixed fine in water, no big deal, and I poured it on my plants, no problem. The warning label is enough to put the fear of God into you, however, so take care when using this stuff. I can't vouch for its effectiveness as I just started using it. Expensive stuff, however, though Ki was able to find a decent price for the powder.
