*520  $aFree-living plant-parasitic nematodes (free-living PPN) appear to be an increasing problem inNorwegian agriculture and their efficient management is required. Methods of efficient nematodemanagement have been sought for personnel involved in farmer’s advisory and among farmers. Inorder to clarify the nematode situation in different agricultural crops a pilot project for surveyingfree-living PPN was conducted during the growing seasons 2016 and 2017.The Norwegian Agricultural Extension Service were involved in selecting major crops and selectedrepresentative areas for sampling. Complementary to the survey was that the samples should becollected form crops showing symptoms of nematode damage. Nematode damage occurs where largepopulations of nematoder are present in fields and shows as patches of poor plant growth.In total, 100 samples (soil and plant roots) were collected from 14 counties and 46 municipalities.The crops samples were potato (n=12), vegetables (n=37), strawberry (n=14) and cereals (n=37). Thesamples were brought to the nematode laboratory of NIBIO, and nematodes were extracted by theSeinhorst elutriator (Seinhorst 1988) and mounted on microscope slides for observation.Many species of free-living PPN were detected in association with damage across a number of cropsincluding potato, vegetables, strawberry and cereals.Certain nematode groups (stunt-, spiral-, root lesion-, pin nematodes) were present in all crops,while Longidorids and Trichodorids were present only in potato, vegetables and strawberry. Thesheath nematode Hemicycliophora occurred only in carrot.
