Abstract

Potato spraing causing brown corky arcs and spots in tuber flesh, has become a severe constraint to potato production in Scandinavia. Field studies were carried out during 2005 - 2006 to appraise brassicaceous amendments against trichodorid nematodes, the vectors of tobacco rattle virus (TRV) that causes spraing disease. The trials were settled in a small grain-potato rotation fields in Central Sweden. Three cover crops, Caliente mustard (Sinapis alba and Brassica juncea blend, cv. Brandt 119), oil radish (Raphanus sativus, cv. Colonel) and arugula (Eruca sativa cv. Nemat) were tested and compared to a bare soil. The cover crops reduced nematode populations at all different locations although the suppression level differed among locations and cover crop species used. Substantial yield improvements were also recorded
