EIP Project KARTOZIK (bact. potato tuber wilt)

Through the synergy of the EIP-agri project „"Management of Bacterial potato tuber wilt for the preservation of potato cultivation and value creation through marketing and processing"(KARTOZIK) with the EIP project SIKAZIKA, an extensive coverage of the distribution area of bacterial potato tuber wilt is aimed at as well as the establishment of an impressive methodological competence for the plant material examination.

Background of the project KARTOZIK

A new disease known as "bacterial potato tuber wilt" is endangering potato cultivation in Hesse, Rhineland-Palatinate and Baden-Württemberg. The disease is caused by two bacterial pathogens, the proteobacterium Candidatus Arsenophonus phytopathogenicus and the Candidatus Phytoplasma solani , and is transmitted via the reed glasswing cicada (Pentastiridius leporinus ). The adult reed cicada flies from May to September. During this period, the female lays eggs in potatoes and sugar beet, where the nymphs develop. The symptoms on the potato caused by the disease are diverse and lead to significant crop losses in severe courses, up to complete failure.


Project objective

Together with farmers, companies from the upstream and downstream sectors and researchers, the aim is to find solutions with high practical relevance in order to preserve potato cultivation in Rhineland-Palatinate. The focus is on the processing potato and the late table potato, as these are particularly affected by the new disease and enable a year-round supply.


Project approach

The core of the project are field trials at six locations with

  • Regional determination of the number of cicadas
  • Exact trials to test the suitability of varieties

The project includes further work packages:

  • Strengthening the diagnostic and methodological competence of the public service
  • Storage trials with processing and late potatoes
  • Development of management options to reduce infestation
  • Investigation of infection, transmission and spread of the pathogens in potato cultivation

Project leader: Prof. Dr. Elmar Schulte-Geldermann

Project duration: 2024 – 2026

The KARTOZIK project is funded as part of the EULLE development programme with the participation of the European Union and the state of Rhineland-Palatinate, represented by the Ministry of Economic Affairs, Transport, Agriculture and Viticulture. The aim is to stimulate new solutions to problems that increase sustainability and efficiency in agriculture. Each project is managed by an Operational Group (OG). Farmers, scientists, consultants, NGOs and business partners work together in this group.
