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

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.

The Potato mop-top virus causes tuber quality problems. Infection on tubers may be expressed as arcs or rings on the tuber surface, deep cracking and distortions to the skin that compromising tuber quality.

Additionally, avoiding PMTV or powdery scab-infected seed tubers and using cultivars that are insensitive to mop-top can help prevent this problem.
