New host plants of Potato T trichovirus
Ullucus tuberosus (ulluco), Oxalis tuberosa (oca) and Tropaeolum tuberosum (mashua) are reported as new host plants of Potato T trichovirus (EPPO A1 quarantine pest). These plants are Andean tuber crops which are often grown in small plots in association with potatoes in the Peruvian Highlands. The virus was isolated from leaves of naturally infected plants. Potato T trichovirus isolates from these new host plants and potato (Solanum tuberosum subsp. tuberosum x S. tuberosum subsp. andigena) were compared, using PCR and restriction enzyme digestions of the PCR product, and showed no variability.
