A viral disease of potatoes characterized by curved lesions inside the tubers and rings or lesions on the leaves.‘Once growers have encountered spraing in a particular field, it will prove difficult to eradicate.’
- ‘Free-living nematodes are well known as the vectors of the tobacco rattle virus, causing spraing.’
- ‘Early data indicates that Markies has a good resistance to spraing caused by tobacco rattle virus, transmitted by free living nematodes.’
- ‘As the variety is susceptible to spraing and as the nematode is very likely to be present, it is prudent therefore to treat routinely.’
Early 16th century (originally Scots, denoting a brightly coloured stripe): apparently of Scandinavian origin; compare with Norwegian sprang ‘lace, fringe’.
