Identity Name: Potato Spindle Tuber
The potato spindle tuber disease occurs in the United States, Canada, Russia and South Africa. It causes quite severe losses and in some regions, it is one of the most destructive diseases of potatoes (solanum tuberosum). The Potato spindle tuber viroid (PSTVd) was the first viroid to be identified. Natural infections have also been seen in avocados and other solanaceous crops. It attacks all varieties, spreads rapidly, and often occurs in combination with virus diseases. It also attacks tomato but seems to be of little economic importance in that crop. So far PSTVd has not been detected in New Zealand potato crops, but it is possible that infection may occur if growers do not take care. With this in mind this broadsheet describes how they spread and can be controlled and damage and symptoms they cause in potatoes.

Famous quotes containing the word potato:
“The cold smell of potato mould, the squelch and slap
Of soggy peat, the curt cuts of an edge
Through living roots awaken in my head.
But I’ve no spade to follow men like them.”
—Seamus Heaney (b. 1939)
