how soon for fungicide?

charleney(8a PNW)April 30, 2014

Chamblees own-root babies should be coming today or tomorrow. It is too hot to plant today or tomorrow. I am good with new babies and do the water etc.
When and what shall I fungicide them ? I have Daconil, Sulphur and all-in-one. Shall I use any of them soon or when? I have 2 older roses that have a bit of blackspot, even though have sprayed with Daconil.
I know some of you will come up with the right answer. Thank You!

I also just found a tiny amount of advanced disease control!

It's all up to how much you personally want to use fungicide. I live in Black spot hell, I've tried and just cannot possibly go through the season without using fungicide. Daconil didn't work for me, and now I only use Bayer Advanced Garden Disease Control. The nice part about Bayer is it will stop Blackspot once it has started. This way I don't have to spray until I absolutely need to. Last week I saw some Blackspot on two roses so I sprayed those two, but have not done my others that are doing fine. I just watch them closely and start them on a spray program when I see it has started. Bayer has addittional formulas that combine with fertilizer, or insecticide. I prefer to get the one soley for disease as I don't want to kill my good bugs, and I can fertilize with better fertilizer cheaper. So you may want to begin a spray for your roses that are showing blackspot now and wait on your others. Some roses are more likely to get it than others.
