The incidence of potato nematode, Globodera rostochiensis (Woll., 1923) Behrens, 1975, in Slovenia

Abstract

In frame of annual sanitary field inspection and in accordance with the existing legal rules, soil samples were taken in 1999 and inspected for the presence of potato and other cyst forming nematodes. A total of 133 fields with the surface of 371 hectares were inspected. Cysts of yellow potato cyst nematode, Globodera rostochiensis (Woll., 1923) Behrens, 1975, were extracted from samples taken in 1.6 hectare field in the area of the village of Libeliče, the region of Koroška, near the Slovene-Austrian border. Based on this find, an additional, more accurate (net sampling) soil sampling was performed on 10 hectares of fields from which 206 soil samples were taken. Potato nematode cysts were discovered in 48 samples taken from 3 neighbouring fields. A total of 1449 cysts of potato nematode were extracted, 1309 in the first field, 139 in the second and one in the third.
