First report of Globodera rostochiensis in Mallorca (Baleares, ES)

Potato (Solanum tuberosum) is one of the most important crops in the Islas Baleares (ES) covering 1,100 ha mainly around the city of Sa Pobla on the island of Mallorca. So far, only Globodera pallida (EPPO A2 List) was known to occur in the area of Sa Pobla*, where it can cause significant damage if not properly managed. In spring 2000, golden-coloured females were detected in several root samples of plant potatoes. From 2001 to 2003, soil and root samples were collected from 28 fields and analyzed (using the EPPO diagnostic protocol). Mixed populations of G. pallida and G. rostochiensis were found in 14 fields all around Sa Pobla, and G. pallida alone was detected in 2 fields. The proportion of G. rostochiensis in mixed populations was low, rarely exceeding 20%. According to the authors, this is the first report of G. rostochiensis in the Islas Baleares.

* The EPPO Secretariat had no previous data on the occurrence of G. pallida in Islas Baleares.
