The recent discovery of rose rosette disease (RRD) in Florida threatens the State’s $20 million rose nursery industry as well as retail sales and landscape use. RRD is caused by rose rosette virus that is vectored by an eriophyid mite. Already widespread in the Upper South and northwards, this disease affects most rose species and cultivars. Symptoms include thorn and shoot proliferation (“witches’ brooms”), elongated reddened leaves, and distorted flower buds ultimately leading to plant death.
This workshop will review current knowledge about RRD, describe management strategies utilized in Tennessee and discuss potential options for breeding rose resistance to RRD.
