Rose rosette virus can cause major problems for nurseries, landscapers, and gardeners alike. The virus causes the plants to become undesirable and will eventually result in the death of the plant, which affects all segments of the rose industry as well as rosarians and home gardeners. The symptoms of disease on ornamental roses are a yellow mosaic pattern appearing on leaves, increased thorniness, abnormally shaped foliage and early production of lateral buds that make up the witches’ broom. This publication is intended for rose producers and serious rose gardeners interested in technical details of this virus and a mite that transmits it.

Some of the common thrips affecting landscape and nursery plants are described here.
