Host range and symptoms

Natural host range and symptoms

Symptoms mild mosaic or symptomless.
• Lamium album, L. purpureum, Marrubium peregrinum, M. vulgare - mild mosaic or symptomless.

Transmission

Transmitted by a vector; an insect; Cryptomyzus alboapicalis, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation.

Geographical distribution
