The rose mosaic and rose rosette diseases may cause a variety of symptoms, including reduced plant vigor and flower quality. Early detection is essential to control.
Roses have been cultivated as an ornamental for 4,000 to 5,000 years and now are distributed worldwide. Rose virus and virus-like diseases occur wherever roses are grown. Since roses are vegetatively-propagated through budding or grafting, these pathogenic agents are easily spread during propagation. Infection by virus or virus-like agents may cause a wide variety of symptoms. These can range from latent, symptomless infections to mosaic leaf patterns and distortions, severely distorted canes, and finally, plant death. Virus-infected plants tend to be less vigorous and less likely to survive environmental stresses than healthy plants. In addition, virus diseases often detract from the rose's aesthetic quality.
