Rose Rosette Disease (RRD) is caused by the Rose Rosette Virus (RRV) and spread by eriophyid mite (Phyllocoptes fructiphilus),
Wild and ornamental rose species and cultivars are susceptible to this disease. And it has been spreading through much of the wild and cultivated rose population in the Midwestern, Southern, and Eastern United States.
According to the UF/IFAS EDIS Extension publication by Binoy, B. et al, there are many symptoms:
Clustering of small branches (witches’-brooms) (Figure 1). Excessive thorn proliferation (Figure 2). Unusual reddening of the leaves that does not disappear as the leaf matures. Rapid elongation of new shoots. Distorted leaf shapes. Distorted flower buds. Abnormal flower color. Leaf mosaic. Uneven thickening of stem. Distorted sprouting and dieback of shoots. Unusual development of leaves within the flower. Severe yellowing and stunting of plants.

Is There a Cure? There is NO cure for rose plants that exhibit symptoms of RRD. However, the disease may be prevented from spreading to healthy plants by using a combination of good cultural practices and effective management of mite populations.
