Zerotol, to Z or Not to Z

Having both seen and known growers who use Zerotol to fight mold of all kinds, I'm very interested in trying it this year. Has anyone here used it? It is 'Organic', I'm looking for any info from growers that do use it, thanks!
PS I'm not affiliated with any commercial agency or product, just a grower seeking info.

It is a life saver, as an outdoor grower in Oklahoma! I have even used it as a wash at harvest and have not noticed any down side in any way. I feel confident using it at any point in flower, which is essential when you are trying to go a few extra days in cooler, wetter weather in the fall.

I know for tobacco we use a palm oil to control suckered. Same theory, acidic control.

How are you applying it and rolling it into your flower IPM, if you don't mind me asking? I saw it listed using a non ionic sticker spreader for foliar, wetting agent like yucca for drenches.

These 4 things listed (as well as all bio fungicides/ insecticides) are incompatible with tank mixing.

Biosafe, which makes Zerotol used to have an outdoor cannabis program listed on their site. I would tank mix Zerotol with Oxyphos and Azagard, 2 more of their products and apply every week or two. Until later in flower, then it was just Zerotol. I wish I could find that guide again. I'll do some more digging around on their website.

Zerotrol works I'm sure, but it's just h202 and acetic acid. You could always just include those separately in your IPM program too-I would sub in citric acid instead of acetic-the point is just to lower the leaf PH to make it inhospitable to pathogens, and h202 is dirt cheap.

From the manufacturer...

"The addition of the Peroxyacetic Acide (PAA) creates a powerful Activated Peroxygen Compound (APC) which has 10-12 times the oxidation potential of Hydrogen Peroxide. It would take 10-12 ounces of Hydrogen Peroxide to equal the killing strength in 1 ounce of ZeroTol. Next, BioSafe Systems' surfactants and buffering agents add stability to the highly reactive APC, allowing it to remain stable under high organic loading.

The benefit of this added stability is that ZeroTol is non-phytotoxic. Since Hydrogen Peroxide breaks down easily, the instability, combined with the large volume needed for effectiveness, can cause damage to plant material.

ZeroTol's superior killing power when compared to Hydrogen Peroxide was verified in the study Efficacy of Disinfectants Applied to Plant Production Surfaces by Dr. Warren Copes, USDA/ARS researcher. This study was published in the SNA Research Conference Report, Vol. 48, 2003, Pages 12-14 and can be viewed online"

I use zerotol 2.0 (not hc), azaguard, oxiphos, bioceres and sanidate 5.0 (for cleaning hard surfaces and disinfect my systems) from Biosafe in my commercial high pressure aeroponic operation and it's pretty amazing. I HAD pythium, fungus gnats and root aphids. I had everything under control within a week and now use the products as a religious IPM program. Works amazingly. A tad expensive at the beginning but well worth it.
