Witches' broom of rose, a killing graft- and mite-transmissible disease incited by an unidentified agent has increased rapidly in Kansas and Missouri during 19781982. The disease was also found in Arkansas and Oklahoma in 1982. Death of numerous cultivated rose hybrids has occurred in predominantly urban settings, but in rural areas, the disease is providing natural control of the noxious weed Rosa multiflora.
