I'm so jealous you have blooms! I'm weeks and weeks away from that.
Yellow leaves with green spots? Are the leaves dying and falling off, or just hanging around looking splotchy? Does it look anything like the right hand photo in the link below? I've never seen Rose Mosaic in real life, but I guess it's common in grafted roses. I think it eventually causes the plant to decline, but isn't a danger to surrounding plants...
Hopefully someone else will be along to give you more advice! Post some pictures if you can!

Best,

Here is a link that might be useful: spray burn vs. rose mosaic

Thank goodness my leaves don't look like rose mosaic !! I think I just sprayed when the weather got too hot and I saw the rust which is still there. Also I like to water just the bottoms but saw that old rust and watered the leaves which I thought had time to dry before the hot sun came up but not. I'm sure from the size and quality of the bloom that they will do just fine but hated to see all the yellow spotty leaves..

you probably have "Actionema Rosae" / "Diplocarpon rosae". It loves humidity, thus it is common in spring and autumn, rather than in the heat of (dry) summer.
Here products are mancozeb, myclobutanil, zineb, ziram, ferbam, maneb. But beside the funny names, they mostly use copper sulfate to fight it.
BTW: remove and burn diseased lieaves, or the fungus will happily spread.

Did it happen all of a sudden? Mine got that right after the bad heat wave we suffered a weekend or two ago. It was too early in the season for that extreme heat.

Hoove took the words from my lips ... Everyone around here seems to have this.
Roses are shedding foliage where they can, I think, in response to that untimely heat.

Also, many of our roses are markedly paler than their normal colors.
