New Rose Rosette Virus Survey

21 March 2019

BGCI's IPSN network is presently carrying out a research project in collaboration with the UK’s Food and Environment Research Agency (Fera) to assess the distribution of Rose Rosette Virus  in botanic gardens and we are asking gardens to survey their Rose collections for symptoms of this disease.

Rose rosette virus (RRV) is an emerging risk to rose cultivation. RRV is a virus in the order Bunyavirales and genus Emaravirus, it is the causal agent of Rose rosette disease (RRD), it was described for the first time in the US and Canada in the 1940’s. Since then, RRV has spread throughout both countries. In 2017, the virus was found in India, the first finding outside North America. RRV is transmitted by grafting and by the mite Phyllocoptes fructiphilus. The mites are transported by the wind, by insects during pollination, and by contact with clothes or gardening tools. Current control measures include the eradication of infected plants.

See below for images of the symptoms of RRV.

If you would like any more information or observe any of these symptoms in your rose collections please get in touch at
