New pathotypes of the fungus Synchytrium endobioticum that causes potato wart disease were discovered in Sweden in 2017. In the same year, the root-knot nematode Meloidogyne chitwoodi was found and the following year the closely related species Meloidogyne fallax was detected. Following these outbreaks, SLU Risk Assessment of Plant Pests was requested to review the available scientific information relevant for the Swedish Board of Agriculture's decisions on management and control measures.

Read the reports here:

• Options to manage populations of Glododera pallida and G. rostochiensis – questions related to crop rotation, resistance of potato and pathotypes

• Meloidogyne chitwoodi, M. fallax and M. hapla – resistance of plants relevant in Swedish cropping systems

• Utlåtande om rotgallnematoden Meloidogyne chitwoodi och dess förmåga att överleva i vatten

• Synchytrium endobioticum – pathotypes, resistance of Solanum tuberosum and management

• Synchytrium endobioticum – utvärdering av metoden för bestämning av olika raser av potatiskräfta

SLU Risk assessment of plant pests conduct assessments in relation to risk management options upon request from the Swedish Board of Agriculture.
