Management of soft rot Pectobacteriaceae (SRP) is a challenge as there are no control agents available and no effective resistance present in commercial cultivars. In addition, many species of SRP have a broad host range and spread via rotten plant material takes place readily. In this chapter, the possibilities for disease management are outlined. Management is mainly based on seed certification to limit the risks of using infected planting material, and on hygiene and cultivation practices that reduce cross-contamination within and between seed lots. Balanced nutrition also supports the suppressiveness of crops against SRP. Experimental data show that inoculum in seed tubers can be reduced by thermotherapy and the use of biocides. Under controlled conditions, application of seed potatoes with biocontrol agents has showed promising results but few data are present on the efficacy of biocontrol in the field. Resistance in wild Solanum species against SRP has been found but to date no genes have been transferred to cultivars. However, new breeding technologies, such as CRISPR/CAS 9 and the use of true potato seed (TPS), will give us new perspectives on the generation of resistant cultivars.
