"The sugar-beet nematode is one of the most serious of the beet pests. It appears to have been imported with some shipments of beet seed many years ago. It has been found widely scattered in four of the western sugar-beet States and probably exists in other States where beets have been grown for several years. The sugar-beet nematode is the cause of a great deal of loss to the beet grower through reduction of his tonnage, and of a corresponding amount of loss to the sugar producer through reduction of the output of sugar. This bulletin treats of the nature and distribution of the sugar-beet nematode, indicates the most probable means by which this pest is spread, and suggests preventive measures and practical means of control." -- p. 2
