Extract

The history of the beet-strain of Heterodera schachtii in Germany, where it was first recognized in 1859, and its subsequent discovery in other beet-growing European countries and the United States of America, have already been described in some detail in a Memorandum published by the Imperial Bureau of Agricultural Parasitology. This Memorandum was published in 1931 with the object of emphasizing the potential danger of Heterodera schachtii to the sugar-beet industry, then comparatively newly established in Britain. Observations carried out in America are quoted, which strongly indicated that the eelworm was introduced into the United States by the use of seed imported from European countries where the infection was known to be intense and of long standing; this contention, however, does not yet appear to have been decisively proved. The danger of repeated beet cultivation, without regard to rotation of crops, was particularly emphasized with reference to the wide distribution of the potato-strain of H. schachtii in Britain, and such infections as were already known to occur on other host-plants were noted.
