Abstract
Carrot plants with severe leaf reddening and stunting symptoms caused by carrot motley dwarf disease were observed in the South Island of New Zealand. Carrot red leaf virus (CtRLV), Carrot mottle mimic virus and CtRLV-associated RNA (CtRLVaRNA) were shown to be the components of the virus complex causing the disease. CtRLVaRNA is reported for the first time in New Zealand.
