Hi Gerry,

I want to know this also. I have a lot with powdery mildew here.

Oh.. remember how we talked about dark colored/chocolate colored leaves? The ones that I have with this coloring are the ones that have the biggest amount of PM.

No blackspot here to speak of.

I know I have read on other forums that the more experienced hybridizers pull the weaklings and the diseased right away. I would guess their experience has shown them that the disease resistance does not get better. PM however I would think could be dependent on growing conditions.. outside vs inside a greenhouse?

Marleah,

I have also heard of the big breeders culling the bad roses from the start, but it is such a painfull process for the amateurs like you and I, wish I had enough space to plant them and see...maybe time for a new raised bed.

sigh...Gerry

Gerry,

How big are the seedlings?
You might give them a spraying with something and see if the "disease" resolves if they are hardy enough to stand it?

Have you checked the Rose Hybridizers Association website? They have a forum where a lot of rose breeders- some amateur and some a LOT more experienced post.

You can email me direct if you like and I can send you a link if needed
