Combating Rose Rosette: Pictorial Guide to Rose Rosette Disease Symptoms

Roses are highly valued in nurseries and landscape plantings for their fragrance and attractive flowers. Rose rosette is a serious disease of roses and early identification of the disease is critical for successful management.  This poster was developed to show the range of symptoms associated with rose rosette disease. Depending on the cultivar, the symptoms vary but may include witches’ broom (rosette), proliferation of prickles (thorns), stunting, cane dieback, leaf distortion or discoloration, and blossom blight.  This poster was prepared for display in county extension offices, retail centers, and nurseries to educate clients on rose rosette disease symptoms. Small images that are found in extension fact sheets are less useful since the images are small in size and image quality may be low.  Therefore, this poster has high quality, full-color, large images that can be used to assist in rose rosette disease diagnosis.
