Rose Rosette
(cause not confirmed): This disease has all the characteristics of a virus infection.
The disease agent is transmitted by a microscopic sized eriophyid mite. Symptoms
include distorted, small leaves, short internodes, red pigmentation of foliage
and excessive thorniness. Infected plants generally die within one year. Hybrid
tea roses are poor hosts for the mite. Rose rosette has not been identified in
landscape plantings in Texas but has been diagnosed in multiflora rose.
