Zyperiris, the odds were/are so bad with that many around. They are not aggressive which is a plus. I have a neighbor who is afraid of everything. Like if you have a tree she thinks it is going to fall on the house so she cuts it down! Has traps all over for rats, as if the neighborhood is infested, not. I don't thik she has a bug in her yard! When I moved into my house, ten years ago, she told me horror stories of Eucalyptus trees, branches breaking when kids are swinging, roots so shallow they fall over with no warning. My one giant tree is a Eucalyptus! ( I have always figured if something like that ever happens I have insurance! Not the kid falling from the swing, the tree falling down.haha) Can you imagine her hearing me almost daily out there "hah, I knew it(!), egg sacs", torch lighting, "now where are YOU hiding, I will find you...ahah! told you! I knew you were around here". Torch lights again..LOL I can't believe she hasn't said anything! I hope I am knocking down the population a bit for goodness sake! You know what they are like? Daddy long legs, everywhere! Except outside! Whew.

Those combo Bayer products aren't very efficient. You'd do better with a "real" fertilizer, and something else for fungal disease. OTOH, I believe that the best way to avoid fungal problems with roses is to plant roses that are not much troubled by fungal disease where you grow them. Gardening knowledge is really, really, local. I know there are folks in your area on the Antiques rose forum -- I bet there are some here, as well. They could give you the most accurate advice. Like Michael, I can't see enough of the symptoms to diagnose the disease. Blackspot is uncommon in my area -- but those speckles look awfully small for that. If you have access to a flatbed scanner, put a leaf in the scanner, and scan it, and we can get a really good look at it.

I think it's just an old spent bloom that needs dead heading. Botrytis would effect all the blooms not just the old ones. You'd see brown edges on all the petals even the tight buds. And the buds would probably not open all the way like the one on the right is. Different varieties will age in different ways. Some hang on to their petals and get the used kleenex look while others will simple drop all their petals.

The only thing I have seen similar to that is lace bugs on Azaleas. They suck the life out of leaves. I had to use a topical bug spray and an insecticide to get rid of them. But check with some local garden people in your area before you do anything.
