Stubby root nematode (SRN) represents an economically important group of nematodes belonging to the genera Trichodorus and Paratrichodorus. Stubby root nematodes often are found in light (sandy) soils and are more problematic when cool, wet soil conditions exist. For example, yield losses as high as 50 percent can be observed in cool and wet growing seasons.
More information about identifying SRN injury on sugar beet, management options, and soil sampling procedures for nematode analysis can be found in the fact sheet https://www.ag.ndsu.edu/pubs/plantsci/rowcrops/a1821.pdf.
