I've never seen any kind of fungi on my 3 Theresa's, ever in all my rose growing years, she is probably the most disease resistant rose I have.

Are you getting lots of rain hot humid weather this year, is it overcrowded, are you overhead watering are all causes of PM?

Btw, Bugnet is pronounced "boo-nay" not "bug-net", lol, I've always pronounce her Bug-Net!

My TB bush is clean as well. Actually all of my roses are doing quite well. With the exception of Morden Ruby which is terrible with BS again this year and Folksinger which has mildew again.

At this time of the year, I do not worry about diseases on my roses. In the spring, I tend to spray. Although I didn't have to this year.

I guess I will simply not look at it close-up but only from the house where it looks very nice with its clusters of bright pink blooms.
Sharon, We have had hot drying winds pretty steadily the last few weeks. I never water overhead and if she is crowded it is only because from her own rapid growth. Here is a quote from Paul Barden's website which I also tried to no avail.
" Daily syringing of the foliage for a few minutes in the morning will eliminate mildew, as mildew cannot survive in a water-soaked environment. Believe me, it works, and is very appealing as an alternative to chemical sprays"
Thanks for your help.
