Publication North Dakota Fresh Market Potato Cultivar/Selection Trial Results for 2020
Potato cultivars or selections included in this report were selected from recently released cultivars, advancing selections with release potential (numbered lines progressing through the trial process), or cultivars that are new to the U.S. Standard potato cultivars used by growers served as checks. The agronomic data presented in Tables 1 and 2 were analyzed statistically. These analyses allow the reader to ascertain, at a predetermined level of confidence, if the differences observed among cultivars/selections are reliable, or if they might be due to error inherent in the experimental process.

Publication chemical/x-pdb Potato Tuber Viruses: Mop-top Management
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. Care must be taken not to infest fields with PMTV from known powdery scab and PMTV infected fields. Additionally, avoiding PMTV or powdery scab-infected seed tubers and using cultivars that are insensitive to mop-top can help prevent this problem.

Publication ECMAScript program Powdery Scab of Potatoes
Spongospora subterranea f. sp. subterranea (referred to as S. subterranea), the causal agent of powdery scab and root gall formation in potato, is a soil- and tuber-borne funguslike pathogen. S. subterranea first was reported in the U.S. in 1913. During this same year, the disease was found established in potato-growing states such as Maine, Florida, Minnesota and Oregon. To date, the pathogen can be found causing disease throughout the U.S., as well as several other potato-growing regions around the world.
