Abstract: Since the detection of Globodera rostochiensis in Belgium in 1946, few studies have been conducted on the spread of potato cyst nematodes (PCN). Some farmers use crop rotation and resistant varieties for the management of PCN, but lack information about the degree of field infestation and the pathotype present in their field. In a recent survey in the north of Belgium, PCN was found in 8.6% of 1320 fields that were sampled by taking 60 soil cores per hectare (about 2 kg of soil). Species identification of cysts of 60 fields showed that 56 were infested with G. rostochiensis, three contained G. pallida and one field was infested with both species. The survey will be expanded to other regions. A test for choice of cultivars, performed in closed containers, was optimised for pathotypes of G. rostochiensis and made available for farmers. The test will be adapted for G. pallida. Detection of cysts in fields needs improvement. Several infested fields were sampled intensively to measure the nematode distribution. The data will be used to simulate a typical distribution pattern for Belgian fields and develop an adequate sampling scheme.
