The sugar beet cyst nematode (Heterodera schachtii) is a major parasite of sugar beets; however, a wide range of other nematodes can damage sugar beet. The most common are root knot nematodes (Meloidogyne incognita, M. javanica, M. arenaria, M. hapla and M. Chitwoodi), stubby root nematodes (Paratrichodorus or Trichodorus species) and the beet crown nematode (Ditylenchus dipsaci).

Sugar beet cyst nematodes

The sugar beet cyst nematode causes serious stand and yield reductions wherever sugar beets are grown. They were first identified in 1859 on sugar beets near Halle, Germany, by Professor Dr. H. Schacht, and were first observed in the United States in 1895. Today, H. schachtii is present in sugar beet-growing countries throughout the world and can be found wherever sugar beets are grown. This embraces Europe (from Spain to Finnland), Russia, Turkey, Israel, the United States, Canada, Australia, and South Africa.

Root-knot nematodes

Root knot nematodes (Meloidogyne incognita, M. javanica, M. arenaria, M. hapla, and M. Chitwoodi) occur in tropical and temperate climates.

Stubby root nematodes

Stubby root nematode (SRN) are mostly found in light/sandy soils and are more problematic under wet and cool soil conditions.
