The Old and the New: Two Needle Diseases of Spruce in North Dakota - F1680

Premature needle loss of spruce is the result of a variety of causes: improper planting, environmental stress, insect pests and disease. Rhizosphaera needle cast and stigmina needle cast are two of the most common diseases associated with spruce needle loss in North Dakota.

Pea Seed-borne Mosaic Virus (PSbMV) in Field Peas and Lentils - PP1704
Pea seed-borne mosaic virus (PSbMV) is an economically damaging viral pathogen of field peas and lentils that can cause significant losses in seed yield and quality, especially when infections occur before or during bloom. It has been observed on field peas and lentils in North Dakota and on field peas in Montana. PSbMV is distributed worldwide, and it presumably was introduced to North Dakota and Montana on seed imported from other regions.

Fusarium Yellows of Sugar Beet - PP1247
Fusarium yellows of sugarbeet was identified in the Red River Valley in a few fields between Moorhead, Minn., and Drayton, N.D., in 2002. Fusarium yellows is caused by the fungus Fusarium oxysporum f. sp. betae, although other Fusarium species can be involved as secondary invaders. The disease causes significant reduction in root yield and recoverable sucrose. In storage, the quality of infected roots may deteriorate more rapidly than in noninfected roots.
