Extract

Heterodera schachtii Schmidt, 1871, first discovered and studied by Schacht in 1859 was recognised as a parasite injurious to the sugar-beet by Ktihn in 1881. Subsequent to the discovery of its pathogenicity it has been studied by many observers both in Europe and in the United States where it was introduced about the beginning of the present century, and has now become established in the beet-growing areas of Utah and California. A detailed morphological account of the nematode was first given by Strubell, 1881, who carried out his observations on material obtained from sugar-beet. Other workers have supplemented Strubell's description in several minor respects and have also described the nematode as it occurs on other plant species.
