Rose Rosette Disease: A New Disease of Roses in Florida

Figure 1. Clustering of small branches (witches’-broom)

Rose rosette disease is an incurable, destructive disease that affects both wild and cultivated roses. Over the past several decades, the disease has spread over much of the U.S., though it was first observed in Florida in 2013. This 6-page fact sheet describes the symptoms and diagnosis of the disease, as well as the cultural, chemical, and, possibly, biological controls that can minimize its spread. Written by Binoy Babu, Mathews L. Paret, Tim Schubert, Carlye Baker, Gary Knox, Fanny Iriarte, James Aldrich, Laura Ritchie, Carrie L. Harmon, and Svetlana Y. Folimonova, and published by the UF Department of Plant Pathology, May 2015.

Wildflowers Susceptible to Deer Damage in North Florida (WEC315/UW360)

Figure 2. Most deer browsing of wildflowers occurred at night.One sure way to prevent deer damage to your landscape is to choose plants that deer do not like to eat. Unfortunately deer foraging preferences vary geographically and studies conducted with captive deer aren’t always accurate. So UF/IFAS wildlife researchers investigated the foraging preference of wild white-tailed deer at two sites in Gadsden County with high deer densities for two years. Of 11 wildlfowers tested, four were very susceptible to browsing: fringeleaf tickseed, Florida tickseed, coastalplain tickseed, and orange coneflower. This 4-page fact sheet was written by Holly K. Ober, Lucas W. DeGroote, James H. Aldrich, Jefferey G. Norcini, and Gary W. Knox , and published by the UF Department of Wildlife Ecology and Conservation, December 2011.
