Camellia yellow
mottle virus

Camellia yellow mottle virus affects only camellias and the leaves develop a bold mottled pattern of dark green and pale yellow. The disease appears to develop slowly within the bush, with initially only one or two branches showing infection. Viruses require vectors to spread them between plants and these are most frequently sap-sucking insects such as aphids, but the vector of this virus in camellias is unknown. There is no treatment other than prompt pruning out of infected branches. It appears to have little effect on vigour or flowering and is often tolerated, since it poses no threat to plants other than camellias.
