Leaf-feeding Weevil in Sugar Beets

A leaf-feeding weevil, Tanymecus confusus, first was observed feeding on sugar beets in the southern portion of the Red River Valley (Richland County, N.D., and Wilkin County, Minn.) in 1975. The weevil has since caused problems for growers in southern Minnesota (Big Stone, Chippewa, Lac Qui Parle and Swift counties) in 1992 and 1997, and again in Richland County of North Dakota in 2004. A related species, Tanymecus palliatus , is an occasional pest of sugar beets in Europe. Feeding injury by adult Tanymecus confusus typically occurs in small areas within sugar beet fields. Damage is occasionally severe enough to require replanting.

Soybean Gall Midge and White-mold Gall Midge in Soybean

This publication describes two species of gall midges that infest soybeans. Soybean gall midge is an invasive and economic insect pest of soybeans that occurs in five Midwestern states (Iowa, Minnesota, Missouri, Nebraska and South Dakota). It does not occur in North Dakota yet. The white-mold gall midge is native to North America and is not economic insect pest of soybeans. Larvae of the white-mold gall midge can be found feeding on Sclerotinia white mold disease in stems and pods. This publication describes how to scout and identify the two species based on their location on plants, field symptoms and plant injury symptoms.

Stubby Root Nematode and Sampling in Sugar Beet

Stubby root nematode (SRN) represents an economically important group of nematodes belonging to the genera Trichodorus and Paratrichodorus. SRN often are found in light (sandy) soils and are more problematic when cool, wet soil conditions exist. For example, yield losses as high as 50 percent can be observed in cool and wet growing seasons.
