Sources and Pathways of Contamination of Potatoes by Soft Rot Erwinias in Scotland
Erwinia carotovora subsp. atroseptica (Eca) causes potato blackleg in the field in temperate climates and together with E. carotovora subsp. carotovora (Ecc) is commonly associated with tuber soft rot in the stored crop. Blackleg is a seed-borne disease and its development is affected by several factors, of which environmental conditions, especially wet soils, which favour growth of the bacteria, and the level of contamination of the seed tubers by Eca are the most important.
