What a great bunch of photos Jean. I had no idea that was canker. What exactly is canker? I thought that was winter damage.

Oh, I think I must look up Downy Mildew. I think that is what mine have.

Thanks Jean!

Hee, Patricia! That was funny!

Jean, thanks for posting the pictures--I usually can't tell the difference between regular blackspot, athracnose and cerospora. I better bookmark this.

Carla -

Downy mildew starts out purple and the leaves turn yellow practically overnight and drop. It generally starts at the top and works its way down. Blackspot works from the ground up.

Patricia - everything in this post was taken in my garden except the RRD pictures. I don't have to sneak anywhere to get pics of rampant disease. :-) Besides, we all know your garden is impeccable.

Thank you Jean. It is not Downy, I know that. It's either Anthracose or just BS. But it doesnn't look like BS. I have someone on the case. No doubt, your pictures are always a great help.

Yeah, it is about time again.

For those who are new to roses or just need a refresher, Jean posted these photos. Thank you again Jean!!!

What do Japanese beetles look like? I think I've got something where I planted my Graham Thomas, don't know if they came with the rose or were lurking in that spot, icky brown things, maybe the size of a dime.

Wow that is a great set of photos, really helpful.

Is canker a really bad one? What do you do to "fix" that problem?

cziga - the cure is pruners. As in remove it. A spray with fungacide afterwards is thought to be helpful. Canker is the major reason I grow ownroots - in my experience they are less susceptible and if infected suffer less damage.

That sounds easy enough. Every time I see a disease or problem of some sort, I start getting worried :) There are so many major things that can go wrong . . .

Subk on the rose forum was looking for a way to find Jean Harrison's threads - so I found this classic thread and bumped it from 2007. The other one I like is her list of No Spray roses which I'll also bump up.

You can do a search for recent threads using the search function w/in gardenweb or for older threads just do a google search, something like gardenweb antique rose jean (or whatever you're looking for). Someone may know a better way to find things, but this works okay.
