The assessment of phytosanitary risks from imported soil entails recovery or assay of soil‐borne organisms, determination of pathogenicity and consideration of potential distribution as affected by environmental factors. Results are presented of examinations of soil from imported plants for nematodes and other pests. Nematodes were much more abundant than other pest groups. Plant‐parasitic nematodes were more common in natural soils than in potting composts, and non‐indigenous species were apparently more frequent from non‐European than European sources. The chief nematode hazards for northern European countries may be from new «pathotypes» of Heterodera species and ectoparasitic dorylaimid genera that include virus vectors. Nematodes and other organisms from tropical areas can become glasshouse pests in cooler climates.
