I'd like to see someone with an actual controlled experiment with dosed and non-dosed comparisons. Also, IMO the leaf color doesn't really indicate much. It's difficult to say whether a lighter or darker color is healthier for a plant. I mean if we never seen a plant before we might assume that red coloration means less healthy since the plant is technically stressed and spending energy on pigments that don't improve reproductive success.
That being said, Azoxyatrobin completely removed all mold from my pot of flower stalk cuttings. All the cuttings that didn't take were molding up and starting to spread from my cuttings that were still green, but after flooding my pots with Azoxyatrobin all the mold went away and never came back. I'm pretty satisfied with it in that regard.
I'll probably do another dose on my mature plants before dormancy. Last year I used Bayer 3-in-1 and it was a horrible experience since it made all my traps weirdly curved (see this post: post388370.html
) probably due to the Tebuconazole. I've since then used that on my cephs, but it also seems to do nothing at all against powdery mildew.
