Description

Potato cyst nematodes (Globodera rostochiensis and G. pallida) are among the most devastating pests of potato. Once contaminating a potato field they are difficult to control because the resting forms – cysts – can persist in soil for many years. Potato cyst nematodes occur in some potato production areas in Finland, but they have not been found in the High Grade seed potato production area. Root knot nematodes (Meloidogyne spp.), potato rot nematodes (Ditylenchus spp.) and the lesion nematode (Pratylenchus penetrans) are new threats to potato production in Europe. They do not form cysts, but they invade the tissue of potato tubers, stay alive in storage and can be transmitted in seed potatoes. The risk of their spread to Finland is of concern in the potato sector. This project will enhance the research capacity, especially DNA-based diagnostics, in detection of the new nematode species in Finland. Occurrence of the new nematode species in Finland will be surveyed and the races of potato cyst nematodes will be studied. Risk assessment will be done with all potato-infecting nematode species using the new FinnPRIO program optimized according to the local conditions, which allows focusing to the species with the highest risk and potential to cause economic damage. Distribution of the costs and benefits among actors of the potato value chain will be modelled and the most economical and motivating means to control potato nematodes in farms and the potato sector will be determined. Information will be made available to farmers and the whole potato sector.
