Potato Virus H found on tomato in China


During a field survey in Yunnan Province, China, in July 2023, tomato plants (Solanum lycopersicum) were reported to show leaf yellowing, leaf curling and abnormally shaped and coloured fruit. Molecular tests revealed this was caused by Carlavirus chisolani (Potato Virus H, PVH – EU A1 quarantine pest). Inoculation tests fulfilling Koch’s postulates confirmed that C. chisolani is pathogenic to S. lycopersicum. PVH was first described in 2014 on potato (Solanum tuberosum) (EPPO RS 2015/056).
