The sugar-beet nematode has now become of importance in Utah. It occurs in spots in practically all of the older beet-growing districts and in a few parts of the state in much larger areas. The intensity of infestation varies from mere traces to nearly complete occupation. One of the areas of severe infestation in Utah on a large area is in the Lewiston district, of northern Cache Valley. The survey here reported was undertaken in order to find the extent of nematode infestation in Cache Valley and the possibility of its control by ordinary cultural practices.
