Phytophthora rubi is the principal cause of root rot in red raspberry. Originally classified as a variant of P. fragariae some now consider it a distinct species (t Veld 2007). This organism has been isolated from raspberries in Europe, North America (Wilcox, Scott et al. 1993), Chile (Wilcox and Latorre 2002) and other many countries around the world. It is best controlled through a combination of good management practices and use of resistant varieties. It is a significant cause of crop loss in poor draining soils.
