Wow! Thanks so much for doing that. I'll be extremely interested in their response!

Please reach out to me when you get a reply.

No, Syngenta did not respond. I found that all Azoxystrobin sc labels state to mix only as much as you can use for one application - do not store the mixed product.
I did purchase the 16oz Azoxy 2SC from the ebay seller as he proved to my satisfaction that he had purchased a bulk quantity and that he couldn't use it all.
I'm doing some testing on application rates based on the label rate of .4oz mixed with 2 or 4 gallons of water, I'm calling the 2 gal. rate "full strength" and the 4 gal. mix is half strength.
For a 32oz spray bottle I added 3ml of the Azoxy 2SC and of course half strength only add 1.5ml.
I am testing both strengths currently in comparison with similarly sized vfts - treated vs non treated but this is the beginning of dormancy so not sure what will happen.
I do have bottles and pipettes that will work for mixing if someone wants a few ounces, but I want to confirm the application rates first. Feel free to check my math.

Definitely let me know how your experiment goes. So what, are you using the entirety of those spray bottles on your application?

Sure thing, should know something in a few weeks.

I mixed two 8oz test batches of the Azoxy 2SC, the first batch was half strength applied to one of two similarly sized Dragons Breath vft's for comparison. The second batch was full strength applied to one of two similarly sized pots of recently divided B52's and one of two similarly sized pots of recently divided SD Kronos vft's for comparison.

Since this is dormancy time, I'll be happy if the test plants just survive the Azoxy 2SC application any observed improvements I'll take as a win win.

Follow-up to my experiment done last fall.

The application was done during dormancy (mid-September) so not much happened; one plant showed some increased greening, none of the plants were harmed and I used both the 2- & 4-gallon rates on different plants and they all look fine today as Spring brings new growth.

I'll reapply three times during this growing season in April, June & August for a new test using the "full strength" two-gallon rate.

Hey Dan, how's progress on this going?

Nothing died! lol Spring growth coming on strong now, so I won't be able to judge leaf retention until later this Summer. Some plants that were really red under my led grow lights seem to be retaining their normal color that they would have under full sun.

I must say, I'm especially curious about how well this works as a fungicide in general.

Right now I still only have the Scott's, and rainy/humid season is coming here in Florida...

Actually treating a couple plants rn.

Still unsure about spending $40 on the heritage.

You ultimately only mix enough to use on the spot right? Or did you find it effective even when stored?

I really don't know as I have never had fungus, I have managed to rot a few rhizomes though.

It's been raining here a lot, just missed a tornado, but had hail, I put my remaining Scotts on the lawn last year.

Good luck!

It's pricey for sure.

Yes, I mix only enough for one application as recommended.

I wonder if you could mix a small amount of the granular form in peat and use as a top dressing?

I’m not completely sold on the concept, frankly. There is one guy on YT who is a big fan, but others I have seen state there is little/ no effect.

I think it's important to remember, even if azoxystrobin doesn't act like steroids and make your plant grow faster/better.

It is a valuable anti fungal that is relatively safe for the environment.

This whole thread really talks about how the granular may not work quite as we'd hope when it comes to proper application.

Hence we've been discussing the soluble form. Liquid azoxystrobin.
