Please keep us updated!

I've been intermittently fooling around with azoxystrobin.

At this point I use it at least knowing it is an antifungal and definitely helps my plants in that way.

So really, whether or not it makes them grow better is just icing on the cake!

Glad you're interested! Right now there's not much to report other than that there's not much change in the plants.

I harvested all of the flower stalks but apart from that, there hasn't been much growth to speak of.

I think they're recovering from transplanting and adapting to the new growing conditions. I'll post some new pics tomorrow when the lights are back on.

Here's the latest pics. As you can see, apart from cutting off the flowerstalks there hasn't been much change.

I'll post more once there are new developments.

Keep us posted - to see this documented is very interesting!!!
Might help those of us following (me) if you add a note on each picture. example: Azoxystrobin day (7) and No Azoxystrobin day (7) or something similar........... please.

Took about three weeks or so before I really noticed any increase in the chlorophyll (greening) and growth rate after my last application of Azoxystrobin which I think "more or less" matches Jagasian's results in his 11 second video "SD KRONOS TIME LAPSE"

I didn't notice this until I had poured all of it out onto the plants and I'm concerned that it may have been a much higher concentration towards the end. There was visible white powder residue on the plants after the leaves dried out. I took the liberty of spraying with a small amount of plain rain water to get the residue off the leaves and flower stalks and that seemed to do the trick. The volume of rain water I used shouldn't affect the soil drench.

In the future, I'll have to make sure I keep the gallon jug agitated the entire time I'm pouring it to help prevent precipitation of the azoxystrobin.
I just emailed "Scotts" to ask if the azoxystrobin was water soluble and not a precipitating component of disease ex. I just applied 2.5 gallons to all of my plants and found it nearly impossible to agitate/pour the solution without some remaining undissolved residue in the jug or the cup I was using. So, if azoxystrobin is water soluble we don't need to worry about the residue since azoxystrobin is the only active ingredient listed.

Nice! Thanks Dan V. I'll be very interested to see what they say. It would have to be water soluble, right? I mean it's a granular product designed to be spread on lawns so I'd imagine it'd have to be dissolved by rain and absorbed by the plants roots.

I did a quick google search and found this ...

Solubility :Soluble in water (6 mg/l at 20° C), hexane (0.057 g/l at 20° C), methanol (20 g/l at 20° C), acetone (86 g/l at 20° C), and dichloromethane (400 g/l at 20° C).

Assuming Azoxystrobin is totally water soluble for our purposes and we don't need to be concerned with the residue which would clog a sprayer - I found this...

"Azoxystrobin can be applied as a foliar spray or a soil-treatment prior to planting, as it has a residual effect. It acts as a systemic fungicide which has curative, translaminar and preventative action".

Used as a foliar spray, Azoxystrobin might be absorbed faster than drenching the soil - maybe.

The official response (predictable) from Scotts: Scotts DiseaseEx Lawn Fungicide does not dissolve in water; this product is not meant to be used as a spray or in liquid applications of any kind. The product will not be effective if applied in this manner, and may clog or damage your applicator. We apologize for any inconvenience this may cause.
I think (my opinion only) the D-EX components that are used carry the Azoxystrobin in granular form break down and settle out leaving the Azoxystrobin in solution so I'm not going to worry about agitating the solution and try it as a foliar spray.

Azoxystrobin cured my rot, my "Dutch Delight's" crown rot that is, I think so anyway. As a last-ditch effort, I drenched this vft with Azoxystrobin and a month later new growth started to appear!

I tried this stuff a few years ago and it made ZERO difference in growth, root size or trap sturdiness. It may be good as a fungicide but IMHO has zero effect on growth, etc. All plants were grown outside in full all day Sun.

*UPDATE*

Today was the 2nd application of azoxystrobin and I thought I'd post my updates.

Here are pics of the two pots. I brought them outside to water them and so they could drain. The lighting is also better outdoors for pictures.

I've kept them under identical conditions and they've both put on good growth.

There is some greening evident in the azoxystrobin pot but it's not putting out any extra vigor that I can see. Maybe this will become evident later in the season, don't know.

I've been watering infrequently (maybe every 1-2 weeks) and will likely increase this to a dedicated once per week since the pots are looking a little dry. Please note that the pots are not sitting in standing water at any time so this may not be ideal conditions. Hopefully watering once per week will fix that. I will be watering both pots with pure rainwater for the normal watering schedule.

If you look closely, you'll be able to see the "Azoxy" tag that I've got in the pot receiving the azoxystrobin. The control pot has no label.

I haven't fed them at all yet since I've been waiting for every plant to have a viable trap. I should be able to start soon though. Once I start feeding them, I'll feed them all on the same schedule, maybe once per week.

Hope you enjoy and please let me know what you think!

Looking good, I see some growth and greening.
I found an older azoxystrobin post on the forum today and the "frequency" of application seemed to be the key to enhanced vft growth according to one of the contributors, but no details were given, I may try a two-week schedule on some seedlings or divisions to compare results.

That's a good point. Right now I water them with azoxy and then let them sit for at least week. In theory that should give them ample time to absorb and for the chemicals to take effect.

But with more waterings, they'd get more of the chemical. Hmmm ... maybe an experiment for another year.
