Texas Gardening: Sick Phlox, 1 by sybram

I really need advice on this sick phlox. I spray with Bayer Advanced 3 in 1 Insect, Disease and Mite Control, although, because we've had such high winds I haven't been on a consistent schedule, though I try. This is the second year I've used the wire cage. I thought it might help keep the stalks from falling over when the flowers get so full and heavy. Now, I'm thinking maybe it holds the stalks too close, blocking sunlight from the middle and maybe providing a good fungal opportunity. Tell me if you think I'm all wet. BTW, the phlox will always get black spot(not sure, but looks like the same thing that gets on the rose bush), if I don't keep after it with spray, but I'm able to control it each year. Can't seem to help it this year.
