First report of Potato spindle tuber pospiviroid on tomato crops in New Zealand
Potato spindle tuber pospiviroid (PSTVd - EPPO A2 quarantine pest) is reported for the first time in New Zealand. The disease first came to the attention of the Ministry of Agriculture and Forestry in May 2000, when a tomato grower reported unusual symptoms. A survey on tomato crops was later carried out, and the presence of the viroid was confirmed in 3 sites in the North Island and 1 in the South Island. It is suspected that PSTVd was introduced through imported contaminated seeds. The situation of PSTVd in New Zealand can be described as follows: Present: found only on tomato crops in 3 sites in North Island and 1 site in South Island.
