I sent some photos to Ioannis Tzanetakis who is in the department of plant pathology at the Univ of Arkansas, that is where they actually found the virus that causes rose rosette. This is the answer I got from him.

"The symptoms I see do not resemble rose rosette disease. I do not see any excessive thorniness on the plants and symptoms are not systemic. Have you checked for powdery mildew? The other alternative would be a phytoplasma."

Thank goodness. I have not seen any powdery mildew on the roses. Anybody know what phytoplasma is?
