First report of Globodera pallida in Bosnia and Herzegovina
A systematic survey for the presence of potato cyst nematodes (Globodera rostochiensis and G. pallida – both EPPO A2 List) was initiated in Bosnia and Herzegovina in 2011. Until 2012, only Globodera rostochiensis had been detected in Bosnia and Herzegovina. In autumn 2012, viable cysts were found in 2 soil samples originating from 1 field located in Rogatica (70 km east of Sarajevo). Morphological and molecular analysis confirmed the occurrence of G. pallida in these samples. More samples were collected from the other fields of the grower concerned, as well as from their surroundings, but no cysts were found in these additional samples. A more intensive sampling regime was implemented in the infested field (1.1 ha) and revealed a high infestation of 1 cyst per gram of soil in the infestation focus. The high infestation level and the use of farm-saved seed potatoes by the grower suggest that the introduction of G. pallida probably took place several years before via imports of infected seed potatoes. Phytosanitary measures were taken on the infested field (prohibition to grow potatoes for the next 6 years, continuing sampling).
The situation of Globodera pallida in Bosnia and Herzegovina can be described as follows: Present, first found in 2012 in 1 potato field, under official control.
