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.

Carpenter bees can be a serious pest on outdoor structures made of wood, such as patios, decks, siding of homes, sheds, furniture, etc. The large carpenter bee is the most common species found in Georgia. While these bees are pollinators, mated females bore tunnels into wooden structures to raise their larvae. This tunneling causes substantial damage to wood, and sometimes even compromises the integrity of the structures they affect.
